Binary Code

Today in class we learnt the binary code. This was interesting because although it may look confusing it can be easy to learn once you get the hang of it.
When a computer stores data and instructions, they are processed using Binary code. This is a code that is made up of 0's and 1's. They are recorded as pulses of electric circuits.
1= Electric Pulse
0= No electric Pulse

A binary string of eight digits, for example, can represent any of 256 possible values, and can correspond to a variety of different symbols, letters or instructions. If the circuit is carrying an electric pulse to give a signal its a 1 if not then its a 0. This is the American Standard Code for Information Interchange.

The headings are;
256 128 64 32 16 8 4 2 1

If i were to work out the code for the capital letter F which = 70 i would do it like this;

256 128 64 32 16 8 4 2 1

0 0 1 0 0 0 1 1 0

This is because 64 + 4 + 2 = 70 therefore the code is 001000110

A table for the ASCII table can be found at http://www.asciitable.com/

Lifting the Lid DVD

Whiles watching the lifting the lid DVD, i recongnised that a computer is much like a city. Here are some of the things i learnt.

-It contains busses which transfer information.

-The computer sends messages using a binorary code which is made up of 1's and 0's.

-CPU stands for computer proccessing unit

-RAM stands for Random Access memory

-ROM stands for Read-only memory

-There are output and input devices. Input devices include;

• Mouse
• Keyboard

Output devices include;

• Computer Screen

Bored in the office.

Today is the 8th of Febuary 2010. I am sitting at work, enjoying a nice cup of coffee, thinking to myself why i am still here. As much i love making money, Brisbane is not the place for me. I aspire to do more as 2010 is a fresh start. But what? The questions still circles my mind.
