Define each of the following (Explain – what are they and what do they do.)
1. Personal Computers: Are designed for single person use and can do many things.
2. Central Processing Unit (CPU): The main processor of the computer. Almost all instructions go through the CPU.

8. Software: All the programs, files, and apps in the computer that tells the transistors what to do.
9. Processors: They interpret the instructions from the software. It is the BRAINS of the operations or computer.
10. Hertz: It is what measures the speed of a computer. It is how many instructions a computer can execute per second. 11. Input Devices: (Put examples and definition) Examples: Keyboards and Mice; they allow us to interact with the software and computer.
12. Motherboard: (V+FYI) it holds all the main components in place.
13. Operating System: It is the Master Program – it manages the interaction between hardware and software.
14. Malware: A “malicious software” it can damage your computer.
15. Output devices: (Put examples and definition) Examples: Monitors and printers; show us what the software is up to.
16. USB: (FYI): Stands for Universal Serial Bus – A port used to connect devices like keyboards and flash drives to a computer.
