ComSci is surely an exciting subject. It
presents a lot of challenges our tests are difficult if you don’t study and the
project if you are a procrastinator. ComSci is only easy for those who are
prepared for it. And you know what, ComSci doesn’t like me. Yet.

This is not an ICT System. Why? It does not have a user. |

ICT SOFTWARE

Technology of Information
...or is it?
Some people may define Information Technology simply as the technology of information. Is it really just that?INFORMATION TECHNOLOGY
>>the technology of the production, storage, and communication of information using computers and microelectronics.INFORMATION AND COMMUNICATIONS TECHNOLOGY
>> refers to technologies that provide access to information through telecommunications.HOW DOES DATA BECOME INFORMATION?
1. INPUT (entering data into the computer or other device)2. PROCESS (manipulating the data into information that is understandable to the user)
3. OUTPUT (presenting the information to the user; it must have a context. It could be printed, displayed, heard or in another form)
4. FEEDBACK (it might be used to affect another input into the same system or a different system)
This is actually a cyclical process. The feedback may lead to another input.
