How Computers Came to Life

By the way let me first answer the trick question:

The Williams-Kilburn Tube could successfully store 2048 bits! Apparently that was a lot at that time! Not that much now a days, but during those times it was a great accomplishment!

Now to the things that I learnt today...

• Usually all the cool technology that we use today like internet or computers are usually developed be the military. I believe because they have a lot of money and since national defence is a big issue they can spend a lots of millions on new projects. Want to read more read what I dug up about the computer and the internet.
• In the old days the first computer was Eniac which was the size of the room that worked on wiring. Everytime you had wanted to do something with the computer you have to rewire it again. It had 500, 000 solder joints so maintaining it was also a big thing. So only the military ( you have three guesses to choose which military, and the first two don't count, hehe!) of United States could afford to maintain it.
• Older computers never had a memory until it was invented later using the The Williams-Kilburn Tube for in built memory.
• The main people behind the computer were: instead of me typing it all here just visit this link! A timeline of the History of the computer
• The ENIAC was used to do complex calculations for the military.
• For more information on the ENIAC please visit http://ftp.arl.mil/~mike/comphist/eniac-story.html
  

Oh yeah and MR.C if you are reading this please tell me if I am right or wrong. I would also appreciate if you give me some feedback on my blog!

Will be adding more to this post as I uncover more information.
And another good source is this website that I found that explains all about Eckerts discoveries etc.

My very own podcast!

Well I have some good news, I'm going to be starting my
very own weekly podcast. Speaking of podcasts we saw a movie or a video
podcast by these people. Here are a few key things that I found out about
podcasts.

Want to know more about podcasts take a look at this article I dug up!It's from feedvurner wich explains all about Podcasting!

• You need good hardware


• You need programs like either Adobe Audition or Audacity to make your podcast all
  the more better

Well you can use stuff like sound recorder a tool that comes as default with
xp and other windows versions but it isn't as clear! So I guess other programs
aer the best way togo.

Some things that we should keep in mind while creating a mp3

• while converting the normal wav file to mp3 using codecs use something
  like a 64 bit, so that it doesn't distort!


• Always use the mono channel so that the sound is clear in all types of
  broadcasts


• Normalize the sound so that all the sound is of the same volume.


• Always convert it into mp3 because this way you have more compression
  level and you don't have huge file sizes. Big file sizes might result in no
  downloads of the podcast.

That's right I'm going to be starting my very own
podcast. Infact I've completed a preview podcast of what my podcast is going to
be of, but is going to be a while though until I release it though. So until
then keep checking back later. If you have any suggestion of what I could
include on my podcast then please e-mail me @ beyondteck@gmail.com

Will be adding more to this post later

Podcasting and communications

There are a lot of thing you can do on the internet, it's not just for e-mail and browsing through sites. There is a lot more to it too. I have assembled a list of stuff that you can do on the internet here.

Here are some interesting facts for you!

for networking you need hubs and switches, lots of types of networks

• LAN-Stands for Local Area Network, the computers are connected either wirelessly or using category 5 cable or a RJ 45 cable. The computer can also be connected using 802.11 aor b or g.
  
  
  
  
• WAN-Wide Area Network the network that is more wider, consisting of more lan. The largest wide area network right now is the... you guessed it the internet. This is because it consists of a network.
  

Things that I learnt about RSS

• It stands for really simple syndication
• You get updated information all the time
• It comes to you you don't go to it
• All you need to do is suscribe to the feed

Things that I learnt about Podcast

• Podcast is like a radio show with no commercials
• Podcast is a thing that is like broadcasting on the internet
• You can subscribe to podcasts
• podcasts keep you updated

To manage podcasts a good software is i-Tunes.


I personally for podcasts like i-tunes a lot, mainly because of how it looks(only thing I don't like is the scroll bars looka a bit wierd). I find that anything that apple makes has a really cool look to it unlike other software. Somehow the preview of the i-tunes lured me into downloading it and why now. It's free and it's got the cool mac style styling(i love mac style!) I wish there was a default setting already installed in my computer that would enable me to dress up my windows like mac (you can do that but you need to download some software and patches and so on)

Because I like the mac styling soo much I use firefox in firefox you can dress up the browse to look like a mac browse(too bad you can change the buttons and all that just the elements of the browser can be changed)

Will be adding more to this post as soon as I finish seeing the video of how to create your own podcast. I have a feeling that I'm going to be making my very own pedcas and my audioblog pretty soon.

Cool Downloads

My list of cool downloads:

This is where I put things info about things that I've downloaded or have heard about, which could be useful.

Good Downloads

• Google web Accelerator

Have I tried it out myself?
Yes, even though I have high speed it worked! I found that a page that took 2 seconds to load now loads a coupe of milliseconds faster, but anyways it's worth it I think.

My review of this product: If you have any sort of connection this boosts your page loading speed. It makes your pages load seconds faster. If you have a slow internet connection and want to speed it up this is the way to go. Now you can get extensions like faster fox for firefox (even though it firefox is a bit faster than Microsoft Internet Explorer) but I didn't hear good reviews about it so I didn't venture into downloading that.

• Mozilla firefox

Have I tried it out myself?
Yes, I use the 1.5 beta version (but it is under testing stage still so it has a few bugs)

My review of this product:

Mozilla has come up with this cool product called Mozilla FireFox for windows and mac. Basically it is a web browser that is a better version of netscape navigator and internet explorer put together. But the good thing that I like in it are:

• Faster
• Customizable look so you can dress it up how you want it
• it has cool addons (mozilla calls it extensions)
  
• Most of all anybody can creat a component for Firefox so people come up with genious ideas of how to make a browser better and you can download that extension. Sort of like wikepedia it's always updated.
  

• Winamp Player

Have I tried it out myself?
Nope

My review of this product:
Well until I try it out all I can say is that it looks cooool!

• iTunes

Have I tried it out myself?
Yes, I use the latest windows version which is iTunes 5.0.1.4

My review of this product:
It is really good in the graphics area but not so good in the file managing area. You need to get the hang of it for a while until you can use it properly. If you have any other files like WMA or anything else it converts it to mpeg4. so it you want to keep it in it's original format you can't play it iTunes. But what its good in though is podcasts and all that kind of stuff, as it is easier to manage it.

• Google Talk
  

Have I tried it out myself?
Yes, I use the latest windows version.

My review of this product:
Simple yet good. Almost every thing that google makes is always simple. It has no adds. And tell you when you have an e-mail etc. The best thing about this is that you get to us the Internet Call feature. Google talk has the best call clarity which is better than any other internet messenger that I've used! It is also a really short download.
Cons: Yes unfortunately it does have some minus points. Biggest problem is that no one has it unlike msn messenger and all that. It does not have display pictures or avatars. It does not have e-moticons. Doesn't have custom skins. And you don't have a lot of customization. But I presume that pretty soon google is going to add this and Google talk is still in the beta stages.

Well that's all the reviews I have for now but I'll make sure I update this list regularly. Another thing is that don't take my word for it this is just what I think but I know other people who have faced serious problems and don't like this product. This post is only to inform you about the latest stuff!

All about networking

Today we talked a lot about networking so I have postd all my notes over here.

802.11g is fater than 802.11b

b has a shorter range but is good if you don't want anybody to steal your wireless signals.
g is faster and has more range and is good if you want better info.

Problem with routers is that anybody ca view information that is sent even though it is encrypted. The good thing is that a router is a good firewall because hackers cant clearly reach our computer because the connection is though the router.

Networking , devices and memory!

Networking , devices and memory!

Memory is volatile (temporary).
Bios: Short for Basic Input Output System. This stores the program of what it has to do, previous processes and processes it has to do. When we boot the computer( startup the computer) we see the bios part. Interisting tip, my teacher says that if you press delete when you boot the computer it takes you to the set up.

Now to the memory part.
There are many kinds of RAM available like:
SIMM (the older one): Single In-line Memory Module

(will be writing more on this later)

Picture of SIMM RAM ( taken from answers.com) click on link to access it.
DIMM: Dual In-Line Memory Module
Picture of SIMM RAM ( taken from answers.com) click on link to access it.

(will be writing more on this later)


Hard drive parts :
Actuator Arm this is the part that reads the magnetic code.
Disk platter: The metal disk that revolves around
So what a hard drive does is ti spins around at high speeds and that's when tha actuator arm reads information, writes info etc.

How a cd (compact disk) works:
A cd has what is called pits and lands. If you look at shiny side of the cd you are going to realize that there are sort of lines on the cd (tip look near the edges) that stand out. These are the pits and lands. The pits are the parts that are burned(a cd burner creats pits and lands and puts infor in cd) and the lands are the parts that are flat. So when that laser in the cd drive (yes there is apparently a laser in the cd drive) goes over the spninning cd it can see reflictive parts and non reflective parts. Again we have two stages that the computer can recognize just like the binary code.

How a cd-rw (compact disk re-writable) works:
Well it works the same as the cd but just that the material that is used to create the cd can be melted again into a flat piece and you can use it again and again and again.

Interesing about cd's: If you have ever heard that never touch the shiny part of the disk then well, it's right. But did you know that touching or scratching the top side of the disk is also equally bad. Because this is the side that contains the thing that is like foil so if you damage it the cd is useless. Why is this? Because it ruins the reflictive quality of the cd. This means that no info can be stored. So you can harm cd's by scratching them or leaving finger prints. But you can't damage them using magnets unlike floppys.
CD's also contain more info usually 700MB. DVD's or digital videos, Blue Ray disks etc are the same as cd's but the have their pits and land closer.

Keyboard:
Even wonder how the information gets sent to the cpu?
Actually what happens is this:
There are two milar films with a circuit embidded into them. When we press a key the two milar films touch each other at one point, thus connecting the circuit and sending the signal to the cpu.

Mouse:
A mouse with a ball:
When a mouse turns there is a gear near the notch when the ball moves the gear moves and turns. This movement is detected by a a optical beam.
Laser mouses. More expensive and uses laser to move the cursor. (I will be adding more on this post later on.)

Networking!

Networking is a way of connecting computers. Usually a category 5 cable is used. RJ45 or the ethernet cable is used commonly. This cable looks just like a phone cable but is more thick and the plug is bigger. It has 8 wires in it twisted together in pairs. The telephone wire is called RJ11.
We also use 802.11 technology more commonly known as WI-FI (the short form of Wireless Fidility). This is a networking technology that connects computers using radio waves.

Interesting facts of today:

did you ever know that a previous processors work at 3 volts. I don't know about processors today though I'll have to look that up.
Did you know that AMD stood for Advanced Micro Devices. This is the company that produces microchips, justl like Intel.

Bits and Bites!

This post talks about well...Bits and Bites (well bytes actually), which I actually find quite interesting. It's fascinating to know how much numbers your computer is processing, and how cool it is because it is made up of such complex parts and how smart it is. Then again, we invented the computer (yes they didn't pop out of the sky) so I guess humans are smarter than computers...

So to review the three basic things on a computer are input, output, storage and processing.
Magnetic media is usually used for the storage devices. But cd's use pits and lands to send data. And another thing to remember is computers have only two stages on and off. You can't have a light bulb half off so there are only two stages.
Now to the bits and bytes part.
To store data the computer uses patterns. Also to process data actually the computer uses patterns. These paterns are ofcourse made of 1 and 0 because that's the only thing a computer can understand.
In binary something like 0 is a bit. A single digit is always a bit, if the code is just single then it would be a single digit code. If the code is two digits like 01 then it is a two digit code.
In binary language there are 8 digit codes all made up of 1 and 0.
8 bits make up a byte. So we can say 8 bits = 1 byte.
1026 bytes makes a kilobyte.


Interesting facts
Floppy disk id made up of milar. In floppy disks because it is magnetic media S=1 and N=0 because a magnet too has only two states. So if you want to ruin a floppy disk what is reccomended is take a magnet and bring it over the floppy disk. What this does it changes the polariity of the magnets which causes the code to get all mixed up so the computer cannot read it.. Even if the floppy is locked (you can lock a floppy so that yuo cannot erase any files until you unlock it) this is going to work. Hard disk is made up of metal.

How to write the code!

Just like we use a number system the code also uses a number system. We (humans, hehe) use the base 10 number system but a computer uses the binary system. so here is how we do it in binary.

All about Processor!

These post contains some complex (if you are a beginner of course) notes about Processors, that might be a little helpful for you if you want to know more about how the processor works.

Here is a picture of a processor that I happened to have. It's an intel processor I believe. Click on it to expand. (for your information no computers were harmed to get this cpu) And by the way sorry for the wierd picturs I had digital camera problems while I tried to take them! For more pictures visit http://upload.wikimedia.org/wikipedia/en/f/f2/CPU_with_pins.jpg

Processors are also known as Microprocessors and CPU's. Visit how stuff works, wikipedia for more details.
CPU is the most well known microprocessor.
What a processor is and how a processor works:

A processor is like the brain of the computer that is a "complete computation engine".

The processor of the computer is made up of silicon on which transistors making up the microprocessor are carved or etched. A chip can contain countless transistors.
There are a lot things that make one type of processor diferent from another one.

Here are some the things that judge the quality of the processor.
Transistors- The first processors had about 6ooo transistors.

Processors now a days have about 125, 000, 000 transistors.

Microns- This is the size of the smallest wire in the chip. A human hair is about100 microns!!!!! The old ones had about 6 microns.Microns on a CPU today 0.09 microns!

Clock Speed- Old computers had about 2 Megahertz clock speed.

Computers have processors that clock up to 3.5 gigaherts.

Data width- This is the width of the ALU. The ALU stands for Arithmetic/ Logic unit. The unit that is responsible for the all the calculations.

MIPS- This stands for Millions of instuction per second. So this helps to tell us how fast the CPU is. Computers today can process about 7000 millions of instructions per second.

The microprocessor takes all the descisions. So it can also jump to a new set of instructions based on the descisions.

the things that a microprocessor has:
Adress Bus: this bus sends an address to the memory.
Data bus: Sends or recieves data form the memory.
RD (read) and WR(write) line: Tells memory whether it wants to set or get and addressed location.
Clock line: Lets a clock pulse sequence to to the processor.
Reset line: Resets the program counter to zero. This line can also restart the function
Instructions that change the program counter: Jumps
Program counter: It is a number that identifies the location of a sequence.
What are wire lines: Wire lines are lines of wires that are clustered together.
Cache: The amount of memory that is inbuilt with the processor. The bigger the cache the better the processor.

the processor is also connected to the RAM (randon access memory) and ROM(read only memory)

A microprocessor can perform a lot of instrustions. It microprocessor works on a set of instructions with the assembly language! Since it can perform so many instructions the chip tends to get heated us so computers have a fan to cool it off.
How does it perform those instructions you ask?
Well, what it does is it looks up the sequence of ones and zeroes in its memory through the program counter (see definitoin of program counter above) of course. Then when it identifies the sequence the CPU knows what to do next.The instruction or input we give would be pressing the a key. Then the code is sent to the cpu through the keyboard. The cpu looks it us and then sends a signal to the monitor to display the a!
That's a lot of processing.
The processor uses pins (sometimes) to connect to the mother board. This is how it completes the channel of processes. Like the processor above.

Thigs that a microprocessor takes care of and when the microprocessor goes to work.

Now that you know everything about the cpu or the processor of a computer. I have put together some facts that are interesting and will help you realize how good modern day computers are.
Speed- A computer today can do about a billion cycles per second if it has only one ghz of memory. Usually a computer has about 2 or so ghz 2,000,000,000 of cycles (sorry if I skip some zeros the number is just too big to remember) . AMD Athlons and P4's can go upto 3.06 Ghz!

All information on this post is taken from:
howstuffworks.com- How stuff works
en.wikipedia.org- Wikipedia the free encyclopedia with over 726, 000 articles.
The picture of the processor belongs to me!! (and incase you are wondering, no computers were harmed to get that chip)

Basics of the computer

Basically a computer is a device that allows us to put input and get the output. One of oldest example of the computer is an abacus. It is and was used to calculate math. It works with beads (more on the abacus later). Of course it doesn't work on electricity or anything but if you put input you can get the output.

Digital computers work on electricity (for now atleast). They to allow you to put input and get output. But these computers work on electricity so the only thing it can understand is on and off because electricity only has two states on and off.
A digital computer uses binary language/system. Which is on and off.
In the binary language on is represented by 1 and off by 0.
So on=1 off=0.
Combination of this one and zero makes a set of instructions.

When the computer processes anything the info has to go though a channel of processes in order to give us the output.

Now since the two basic things about computers are input and output. There are also devices that are known as input devices and output devices.
Input device- Put data into the computer
Examples of input devices
- Keyboard
- Mouse
- Trackball
- Digital camera
-Touch screen monitor (even though the monitor is considered out put device a touch screen isn't)

Output device display the data from the computer after being "processed"
Examples of output devices
- Monitor
- Printer
Etc.

There are two types of storage dynamic storage and long-term storage.
Dynamic storage is only there when you need it then it gets erased and long term storage stay there (there refers to the storage device) until you delete it.

E-mail and how it works

Okay this post is for the people who found my previous post a little boring. Brace yourself, because this is for the advanced people (kind of) And In this post I talk about the keyterms in e-mail and protocols and all that kind of stuff... it's useful knowledge to know.

Here are the notes I made on September 13th. My teacher finally got to complete his lesson today so I have added the rest of the stuff in this post!

First of all my teacher handed out my first project which is to find details of specific parts of a computer and do a presentation on it. The details that I found out are stored in this location of the beyond-teck website - .

Now to the notes, which I always put in point form (because it is easy to remember)

Things about e-mail

• There are various folders in your e-mail account
  
  These folders are usually - Compose mail, Inbox, Starred (in g-mail), Sent mail, Drafts, All Mail, Spam, Deleted items, Contacts and the folder that you create.
• Compose mail: This is the place where you go to e-mail someone.
• Inbox: This is the place where all the incoming mail is stored.
• Starred: This is the place where the e-mails that are important for you can be stored.
• Sent Mail: This is where all the messages you have sent is stored.
• Drafts: This is where the messages that are to be sent are stored. To store messages in draft there is usually a button such as Save Draft to do that.
• All mail: This is where all mail messages are stored.
• Spam: This is where unnecessary junk mail is stored. These mails are often related to some commercial purpose. The word Spam comes from a company called Hormel Foods which has a product named that right SPAM. It is a canned meat made largely from pork. For more information go to spam.com Sometimes this folder is also called junk mail.
• Spam is like some of the comments on this page. It has links to various sites. Which makes it kind of like and advertisement.
• Deleted Items: This is where all the deleted items are stored.
• Contacts: This is where you put e-mail addresses of people so that you don't forget. You can add other information too in this section along with the e-mal address of that person.
• Folders that you create: If you want a organized mailbox then my be you should have some of your own folders so that you can sort your mail. For example you can create a later folder in which you can put all the letters that you are going to read later.
• Every account there is always a place where you can change the setting of how you get the e-mail etc.

There are two types of ways with which you can send and receive e-mail.

The first type is web based e-mail account. All the mail is stored in webservers. You read and write e-mail through the internet or webpages. This way you can read all your messages from any computer in any corner of the world.

The second type is e-mail clients also known as mail user agents (MUA). In e-mail client all the mail is downloaded onto your computer. The e-mail client is a software that uses protocols. A protocol (in computing of course) is a convention or standard that controls or enables the connection, communication and data transfer. The e-mail clients use POP3 and IMAP. Due to the fact that a server hosts a your e-mail service you can change the setting for your client to save a copy on the server. You can access this copy form anywhere if your mail service has a website in which you can log onto. The POP3 protocol is to download e-mail but the SMTP protocol is used to send e-mail.

Acronyms of the day:

POP3: Stands for Post Office Protocol 3. This is used to retrieve e-mail from a mail server.

IMAP:Internet Message Access Protocol. This too is used to retrieve e-mail from a mail server.

IMAP4: Internet Message Access Protocol4. This too is used to retrieve e-mail from a mail server.

MIME: Multipurpose Internet Mail Extensions. A specefication for formatting Non ACSII messages so that they can be transferred over the internet.

ACSII: American Standart Code for Information Interchange. This is a code uses numbers to represent normal characters (english characters). The numbers range from 0 to 127.

SMTP: Simple Mail Transfer Protocol. A protocol that is used to send e-mail messages between servers.

MUA: Mail user agents

UCE: unsolicited commercial e-mail

Some things that you need to know about e-mail:

Since e-mail doesn't have emotions because it is just text it can be dangerous and can cause serious misunderstandings.

Also there are many companies that are out there to take your e-mail address and spam you. See Spam explanation above for more details. Also there are some bots that search for e-mail address so that when they get your e-mail address they put your e-mial address in their database so that they can send you spam.

One of the ways to not have spam in your inbox is have many e-mail addresses. So when ever you sign up for newsletters and all that it goes to your e-mail address that is created for that purpose. So this ways your e-mail address with all the important mail is safe.

E-mail

E-mail has now become a big part of our lives and in order to understand how to use that better I've added this post. And yes it's also a part of my notes... you probably know all this stuff but here it is anyways.

The first text box in a web based e-mail client or an e-mail client is always is always the TO: box.
In this box we need to type in the e-mail address of the person to whom we are going to send the e-mail to.
Then comes the CC textbox or the Carbon Copy text box. This is where we type in the name of the people who you want to send copies of the letter to.
The name originates form the carbon used in typewriters. They put carbon sheet ni between two papers so that when the hammer hits the paper it also imprints the same thing on the other paper which is behing the carbon paper. This is called the Carbon Copy.
Then BCC or Blind Carbon Copy
If you want to send an e-mail to a person but do not want him to know who else got the same e-mail then their e-mail address goes here.

Here's some stuff that I dug up myself:

• E-mail is short for electronic mail.
• It is the transmission of text messages and files over a network (usually the internet!)

That's all I could find for now. Will be adding more later to this post.

Still anxiously waiting for my teacher to complete his lesson...

Computers and Computer Parts

Here are some tips that are going to make you a better shopper! Well at least it is going to educate you more about computers. Along with that you are going to learn a few tips about computers and computer parts... well you know them all probably but anyways, it's my homework from business class for today :(

• Always know that a businessperson's job is to sell!
• No matter what he tells you his intention is to sell his product.
  
  
  In order to sell his products he is going to make sure that he hides all the bad stuff and only shows you the best his product has to offer.
• Always research on web sites like Futureshop before you go ahead and purchase something.
  
• Before going to the store do some research!
  

Things that I learnt about computers:

• Processor Type: The brand of the processor like AMD or Intel. Intel is the most popular though. The processor is also called as the CPU or the central processing unit. It works with other devices to perform tasks
  
• Processor Speed: The speed of the processor, or how fast it is. This is usually measured in Megahertz (MHz) or Gigahertz (GHz). The higher the speed the faster the performance is. 1 Ghz is 1000 Mhz
  
• RAM: Random Access Memory. Computers short-term memory.
  
• Hard drive: The bigger the hard drive size the more files we can store. Storage capacity is measured in, GB (gigabytes).
  
• Optical Drives: Drives such as CD drives are known as optical drives because they use lasers to read and write data.
  
• A CD-RW drive can read and write most common types of CD formats

Who am I?

I'm an IT enthusiast currently pursuing high school college in the uber beautiful city of Toronto, Canada. I'm addicted to computers and the Internet.

Enable live bookmarks

To stay updated Mozilla Firefox has this excellent feature called "Live bookmarks". This is a feature that utilizes the RSS feed or Atom feed, however this is easier because you can visit the page right from your browser without any external site of software.

To add a Live Bookmark, just follow these steps and in no time you'll find that you have a lot of live bookmarks.

1. First click on the orange icon in the address bar



2. When you do that a screen will pop up like this one


Here you can specify the name of the bookmark and which folder to create it in.
After you are done just click on okay and you are done!

To access the Bookmarks go to the Bookmark toolbar. There you will see the Beyond Teck folder(or the folder you stored it in) in Bookmarks menu. Then hover over the option that says "Beyond-Teck!" and you can see my recent posts.
