Session 15

We started learning area 02 which is the computer system. Computer system is a combination of components designed to process data and store files. There are 4 major hardware components:-

 i) Input - data and instruction that we enter into the computer system for processing. Example of input device: keyboard, mouse, etc
 ii) Output - data that has been processed into a useful form. For example, printer, speaker, etc
 iii) Processor - is like the human brain. Example: CPU
 iv) Storage - location of data, instruction and information that are held for future use. There are two types of storage. One is the primary and the other is secondary. The primary storage only holds data temporarily like the RAM. As for the secondary storage is considered permanent until data is deleted or removed. For example, thumbdrive, CD, DVD, etc
