Cool Websites – Wolframalpha

This website is really cool, it makes homework so easy. It does complex math and gets accurate facts in an instant. So useful for daily homework. Bad thing is, you need to know how to type in commands to use it. If Google incorporate this into it’s engine, it would be 1 step closer to perfection. Let’s stop the chattering and on with the link.

File sizes – bits bytes

Do you want to know why when you buy a 320GB hard drive, your computer only reports it as 298 GB? Here is the reason why.

Bits bytes heard of it? You may, you may not.
1 bit is a digit in binary, the possible numbers of a bit is either

1 or 0
also means
on or off
also means
5volts or 0volt
also means
electrical flow or no electrical flow 

Sense of scale :
8 bits(b) = 1 Byte
1 kilobyte(kB) = 1024 Bytes
1 Megabyte(MB) = 1024 kiloBytes
1 Gigabyte(GB) = 1024 Megabyte
1 Terrabyte(TB) = 1024 Gigabyte
1 Terrabyte(TB) = 8,796,093,022,208 bits

Why 1 kilobyte is equal to 1024 bytes? This is because of this is way that computer counts(binary 1 or 0). In short, its 2^10.

This means its  2x2x2x2x2x2x2x2x2x2 = 1024.

Hard drive(HDD) manufactures count 1 kilobyte as 1000bytes not 1024 bytes. When you buy a 320 GB HDD, you are getting 320000000000 bytes but since computer counts 1kilo as 1024 it would only appear as 298.023223876953125 GB

This also applies to USB flash drive, RAM etc.

Guide to file types

File types are just extensions to a file name. A dot followed by three letters/numbers or a combination of both.
Eg. picture.jpg

picture is the file name
.jpg is the file type

File type tells the computer what software to open it with, it only do this one specific thing, it does not tell what file is this.

For example

.jpg .png .gif will tell the computer to open it with Microsoft picture viewer(XP) / Microsoft photo gallery(Vista)

.doc .ppt will tell the computer to open it with MS word and MS powerpoint respectively.

You may ask why I can’t see these in my computer, that is because Microsoft hid the file type by default. To unhide it, follow these instructions.

1. Press start and go to control panel.

2. If you something like these (XP/Vista) look at the left bar and click classic view.

3. Click folder options.

4. Under the view tab search for Hide extensions for known file types and untick it.
5. Press OK
 
You should be able to see the file types now.
WARNING:You will need to retain the file type when renaming the file.

Note : Changing the file type DOES NOT change the file’s data.
