Input Components: Examples: Keyboards Microphones Webcams Scanners and etc. Storage devices such as Hard disks and CDs/DVDs. Processing Components: CPU (Central Processing Unit) CPU is the computers main processing component. Executes instructions from the computer's programs. Modern computers are composed of two or more cores and are commonly called multicores. Greater the number of cores, better the overall performance. Output components: Examples: Monitors Printers Speakers and etc. Storage Components: The more storage computer has, the better the pe...
