week 2

It was week 1, Earlier the first class of computer internet, we met our respected lecturer was Mr. Azamuddin and introduce the subject to us. Later on we did Ice-breaking session and got to know each other. In this week, we have learnt what is computer all about and the operation procedure. We also have learnt the decimal, binary, octal and Hexadecimal Number Systems, the computation methods as well.

Later, we learned the five generation of computer from 1970 till now. How computer has changed over years . The computer architecture and categories of computer are also very important knowledge for me. Here is one of the example is the Super computer.

Moreover, we also learnt the system unit components, which are

Ø   Processor                                                

Ø  Memory module

Ø  Expansion cards

Ø  Sound card

Ø  Modem card

Ø  Video card

Ø  Network interface card

Ø   Ports and Connectors

At the same time, we have been taught about the CPU components. Control Unit (CU) acts like the supervisor seeing that things are done in proper fashion. The control unit determines the sequence in which computer programs and instructions are executed. Things like processing of programs stored in the main memory, interpretation of the instructions and issuing of signals for other units of the computer to execute them. It also acts as a switch board operator when several users access the computer simultaneously. Thereby it coordinates the activities of computer’s peripheral equipment as they perform the input and output. Therefore it is the manager of all operations. 

Registers, Main Memory, Volatility, Random Access Memory and Read Only Memory, are all important elements of a computer.

We also have learnt the concept of  input and output device in the end of the week.
