Chapter1 Computer & you• Computer & four basic operations that a

computer performs.• two main components of a computer

system: hardware and software.• Hardware & Motherboard & System Unit.• examples of the information processing

cycle in action.• Two major categories of computers:

individual & organization.

Chapter 1The Client/Server network. Spotlight1: Ethics

How to be a responsible computer user, The ten commandments.

Chapter 2 Inside System Unit• Data representation of computer – Binary

Numbers. (0 - 16) and Hexadecimal. • Understand the data transfer rate and data

storage. Difference between Byte and Bit.• Characters and Character Code. • Main components inside system unit and

their usages. (what’s inside that black box?)

• Motherboard.

Chapter2• CPU – Instruction, Instruction Set. Two main

parts: Control Unit & Algorithm Logic Unit(ALU)• Machine cycle: Instruction cycle & Execution

cycle. Fetch, Decode; Execute, Store. • Factors that determine microprocessor’s

performance.• System clock and Clock Speed. • Parallel processing & Multi-core processing.• Memory & various of memory– RAM; Virtual Memory, Cache Memory. Register. – ROM: BIOS, Power-on Self-test (POST)

Chapter 3 Input/output and Storage• Input device. • Keyboard. Key matrix & Character Map. • Output device. • Monitor & Printer• Monitors: soft copy; Types: CRT & LCD. How

to measure the size. What is Resolution. • Printer: hard copy. Two major types. • Storage: recording media.

Chapter 3 Input/output & storage• Memory Vs Storage. Store data temporarily or

permanently. • Hard disk: – the structure of hard disk. Platter, track, sector,

cluster.– Partitions of hard disk.

• Solid-state drive: Flash Drive; no moving parts; Non volatile.

• CD Drives:– Optical Storage device. – Pits and Land to represent the binary information.

Chapter 4 System Software• System software: Operating System, System

Utilities. • Operating System: Five basic functions. Why

computer need OS?• Starting the computer: – cold boot & warm boot. – Six steps of booting a system. What will happen?

• Managing memory. • Coordinates tasks: Interrupts & Interrupt

handlers; Device driver. • User interface; GUI, menu-driven, Command-line.

Chapter 4 System softwareThree categories of operating systems:

Stand-alone, Server OS & Embedded OS. Examples of these categories.

System utilities. Back up program. Scanning program for these bad sectors.Trouble shooting & safe mode.
