Study Notes

Discovering Computers: An Introduction

Computers are used to process data.
The system unit houses electronic components for data processing.

Computer System Block Diagram

A computer system comprises input, processing, storage, and output.
The central processing unit (CPU) performs calculations and controls other components.
Input devices send data to the CPU.
Output devices display data processed by the CPU.
Storage holds data and instructions.

Von Neumann Architecture

The Von Neumann architecture describes a computer's components and their connections.
The CPU, memory, and input/output (I/O) components interact through buses.
Data bus, address bus, and control bus transmit data.
The CPU (Central Processing Unit) is connected directly to memory through these buses.

Bus

A bus is an electrical pathway for data transfer between components.
Local bus connects the CPU to memory.
Expansion bus connects the CPU to peripherals.
Bus clock speed measures the rate of data movement between locations.
Bus width measures the amount of data moved simultaneously on a bus.

The System Unit

The system unit is a case that houses computer components.
Common components include processor, memory, adapter cards (sound card, video card), drive bays, and power supply.
The motherboard is the main circuit board.
It contains adapter cards, processor chips, and memory chips.

The Motherboard

The motherboard is the main circuit board in a computer.
It contains many components including:
- Adapter cards (sound cards, video cards)
- Processor chips (CPU)
- Memory chips

System Components

Northbridge chips interact with the CPU and RAM (Random Access Memory).
Southbridge chips manage input/output (I/O) devices.
Bus architecture (like FSB, PCI express, USB) connects components and devices.

Chip

A chip is a small piece of semiconductor material.
It has integrated circuits etched on it, designed to carry electrical currents.
Chips are packaged for circuit board attachment.

Processor (CPU)

The CPU interprets instructions and executes them.
The control unit handles instruction processing.
The arithmetic logic unit (ALU) performs arithmetic and logical operations.
Regulators: The CPU has several registers to hold data and instructions temporarily.

Machine Cycle

A machine cycle involves four steps: Fetch, Decode, Execute, and Store.

Pipelining

Pipelining allows instructions to be fetched and processed concurrently.
It speeds up processing time in the CPU.

System Clock

The system clock controls all computer operations.
It generates regular pulses.
The pace is measured in clock cycles/second.
Clock speed is a measure of the clock's operation pace.

Processor Selection

Processor speed, measured in GHz, impacts the computer’s performance.
Faster processors, like those from Intel, are expensive.

Heat Management

Heat sinks, heat pipes, and liquid cooling systems manage processor heat.
These components dissipate excess heat.

Parallel Processing

Parallel processing utilizes multiple processors.
It significantly speeds up tasks.
Efficiently dividing up tasks to different processors is a critical factor.

Data Representation

Computers represent data digitally, using binary system.
A single bit is either 0 or 1.
A byte consists of 8 bits.

Byte

A byte is a grouping of 8 bits.
It can represent 256 different values.
It's used to store characters, numbers, punctuation, etc.
Data is represented by particular combinations of bits.

Coding Systems

ASCII, EBCDIC, and Unicode are common coding systems

Letter to Binary Conversion

Inputting a letter triggers a binary code in memory.
This binary code represents the input character.
Then, the binary code is displayed on the computer screen in the corresponding character format.
