The document discusses the basic components and functions of a computer system. It explains that computers use binary digits or bits to store and process data. It then describes the central hardware components including the CPU that directs operations, and common input devices like keyboards and output devices like monitors. It also outlines different types of computer memory and storage, as well as the roles of software programs and operating systems.

• COMPUTER MEMORY IS MEASURED IN
KILOBYTES(1000), MEGABYTES(1 M),
GIGABYTES(1B), AND TERABYTES(1T)

3. COMPUTER HARDWARE
• REFERS TO PERMANENT PARTS OF A
COMPUTER
• PARTS INCLUDE A CENTRAL PROCESSING
UNIT(CPU), INPUT DEVICE, AND OUTPUT
DEVICE

4. CENTRAL PROCESSING UNIT (CPU)
• DIRECTS THE OPERATION OF THE
COMPUTER, PERFORMS OPERATIONS AND
CALCULATIONS, AND DIRECTS THE STORAGE
AND RETRIEVAL OF INFORMATION

5. INPUT DEVICES
• SENDS DATA TO THE CPU
• EXAMPLES: KEYBOARD, MOUSE, GAMEPAD,
SCANNER, MICROPHONE

6. OUTPUT DEVICES
• PRESENTS DATA FROM THE COMPUTER
• EXAMPLE: MONITOR, SPEAKERS, AND
PRINTERS

7. • Random Access Memory (RAM) – temporary
storage area for data while the computer is
operating.
• Read Only Memory (ROM) – information the
computer needs to operate properly

8. • Used to store information
• Examples: hard drive, floppy disk, cds

9. -instructions that directs the computer hardware to
perform operations
• Two kinds:
– Operating System – set of basic instructions to
keep a computer remaining
– Application Software – grouped by their
function, a particular task a computer can carry
out

10. Computer Programming
• Uses computer language and converts input
information into instruction for the computer
