Hardware Lecture Notes

These flashcards serves as a valuable tool for exam preparation.

Motherboard

The core component of a computer where all devices interconnect.

Hardware

All the physical components of a computer, categorized as critical (essential for booting) or non-critical (functional but not essential for booting).

PCB (Printed Circuit Board)

A printed circuit board that supports components mechanically and facilitates electronic communication through conductive pathways.

Microprocessor

The main component in a computer that interprets instructions and processes data.

Cache Memory

A circuit that enhances performance by storing frequently accessed data for quicker retrieval.

Clock Speed

The rate at which a processor operates internally, determined by multiplying the FSB (Front Side Bus) speed by a specific ratio.

CPU Socket

A connector on the motherboard where the processor is installed, serving as an interface between the motherboard's circuitry and the microprocessor.

RAM (Random Access Memory)

Temporary storage that enables random access to information, facilitating quick data processing.

Expansion Slots

Interfaces that physically connect expansion devices to the motherboard, such as graphic cards and memory.

ROM BIOS

A small, non-volatile memory chip on a motherboard that contains firmware to start the computer and configure hardware settings.

POST (Power-On Self-Test)

Tests the hardware during system startup.

Power Supply

A power supply unit (PSU) supplies the energy needed.

ATX (Advanced Technology Extended)

A standard for PC design that ensures hardware compatibility.

Connectors (IDE, SATA)

Connects disk drives and peripherals; SATA is common.

Dual Channel

These technologies allow a system to access two memory modules simultaneously.

Monitor

Displays the processes occurring inside computers

HDMI and DVI

Used for High-Definition videos.

Overclock

A procedure of increasing CPU Speed.
