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.
