Study Notes
Computer Hardware and Components
- The Central Processing Unit (CPU) is considered the "brain" of the computer.
- Random Access Memory (RAM) stores data temporarily while the computer is running.
- A Hard Disk Drive (HDD) or Solid-State Drive (SSD) stores the computer's operating system, software programs, and user data even when the computer is turned off.
- A Power Supply Unit (PSU) provides power to the other components in a computer, converting AC power to DC power.
- A Motherboard connects and allows communication between different computer components.
- A Graphics Card (GPU) processes and renders graphics for display.
- A Network Interface Card (NIC) connects a computer to a network.
Memory and Storage
- RAM is volatile memory that loses its data when the power is turned off.
- ROM is non-volatile memory that retains its data even when the power is turned off.
- Cache Memory is a small, fast memory that stores frequently-used data.
- HDD uses spinning disks to store data, while SSD uses memory chips.
- SSD is faster but more expensive than HDD.
Ports and Connectors
- USB is a type of computer port used for connecting peripherals.
- HDMI is a type of port used for transmitting video and audio signals.
- Ethernet is a type of port used for connecting to a network.
- Fiber Optic is a type of connector used for transmitting data at high speeds over long distances.
- RCA is a type of connector used for carrying video and audio signals.
Computer Cases and Power Supply
- A Full-Size Tower case provides room for expansion and is commonly found in the corporate environment.
- A Compact Tower case provides limited room for expansion.
- A Power Supply Unit (PSU) provides power to the other components in a computer, converting AC power to DC power.
Cooling Systems
- A Heat Sink is used to cool computer components.
- Active Cooling uses power to operate and typically involves fans or pumps to dissipate heat.
BIOS and UEFI
- BIOS (Basic Input/Output System) provides the firmware for initializing hardware during the boot process.
- UEFI (Unified Extensible Firmware Interface) is a replacement for BIOS, providing improved performance and security features.
Miscellaneous
- Hyper-Threading is a feature that enhances CPU performance by allowing multiple threads to run simultaneously.
- A UPS (Uninterruptible Power Supply) prevents damage to the computer during a power surge or outage and provides backup power.
- A KVM Switch allows multiple computers to share a single keyboard, mouse, and monitor.
