Factors that Affect Performance
CPU, motherboard, RAM and storage devices affect the overall performance of a
computer because all of these components must interact as a system, and a system is
only as efficient as its weakest component.

Recognizing Input/Output Devices Pg 60
Peripheral devices add functionality to the computer, and can generally be classified as input
devices, or output devices. Input or output (I/O) devices enable communication between the user
and the computer.

Understanding How it Works Together
ROM-BIOS chips are responsible for starting your computer, checking system memory,
and loading the operating system
loads the operating system from the hard drive
the operating system is loaded into RAM
When the computer loads the operating system, it passes control over to it
Software application programs are stored on the hard disk drive
When you start an application, the computer loads a copy of the program’s instructions
into RAM
- What is the place on your computer where the operating system, application programs and data in current use are stored temporarily (ie as long as the computer is running) for quick access by the computer’s microprocessor? a. Hard drive b. Read Only Memory (ROM) c. Diskette or floppy disk drive d. Random Access Memory (RAM) e. Flash drive f. External hard drive
- What types of storage media can be damaged by magnets? a. Optical Storage (CDs and DVDs) b. Hard Drives c. Diskettes d. Flash Drives e. Solid State Drives f. Backup Tape
