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 1 The 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 software Three 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.
