Study Notes

Power Supply Installation

Connect the 8-pin PSU connector to the CPU power connector securely.

Memory (RAM) Installation

Open the clips on both ends of the RAM slot.
Align the RAM stick's notch with the mounting slot.
Firmly press the RAM into the slot until clips latch closed.
Repeat the process for additional RAM sticks.

Graphics Card Installation

Remove expansion slot covers from the rear of the case.
Insert the graphics card into a PCI slot on the motherboard, pressing down firmly.
Secure the card using screws.
Connect power from the PSU to the graphics card if required.

Storage Drive Installation

Mount storage drives into designated case bays using screws to secure them.
Connect the drive to the motherboard using a SATA cable.
Plug in the power cable from the PSU to the storage device.
Follow the same procedure for any additional storage drives.

Optical Drive Installation

Remove necessary front panels from the computer case for the optical drive.

Key Computer Components Overview

Hardware: Physical components used for input, processing, and output activities.
Instruction Time (I-time): Duration required for instruction making and decoding.
Execution Time (E-time): Duration to process and store results in memory.
Data Storage: Data storage is now compact; a single DVD holds 4.8 GB, compared to 90 million punch cards to match the same capacity.

Computer Characteristics

Speed: Capable of calculations at remarkable speeds, simulating millions of mathematicians.
Reliability: High reliability, errors usually result from human input, not machine failure.
Multitasking: Ability to perform multiple tasks simultaneously.
Diligence: Computers do not experience fatigue or boredom.
Accuracy: Rarely make mistakes; processing is precise.
Storage Capacity: Can manage vast amounts of data.

Types of Computers

Microcomputers: Small, versatile, and commonly used by individuals.
Mini Computers: More powerful than microcomputers, designed for multiple users.
Mainframe Computers: High-speed processing for managing large data for multiple users.
Super Computers: The most powerful, capable of processing trillions of instructions per second.

Computer Classifications by Functionality

Analog Computers: Use continuous physical phenomena to solve problems, measuring and interpreting data.
Digital Computers: Perform calculations and mathematical operations using binary digits (0s and 1s).
Hybrid Computers: Handle both digital and analog inputs and outputs.

Power Supply Unit (PSU)

Converts AC from the power outlet to usable DC for the computer components.

Peripheral Devices

Input Devices: Include keyboard, mouse, and microphone, used to enter data and instructions.
Output Devices: Include monitors, printers, and speakers, used to present processed data.
Storage Devices: Non-volatile storage like HDD retains data without power, unlike volatile RAM.

PC Assembly Guidelines

Use proper tools: screwdrivers, anti-static wrist strap, and a flat surface for assembly.
Ensure a clean, well-lit workspace to prevent damage to components.
Discharge static electricity by touching a metal surface before working on parts.
Always disconnect power and allow components to discharge before handling.
Avoid assembling individual parts like PSU or monitor in isolation, and handle sharp edges with care.
