Study Notes

CPU (Central Processing Unit) Fundamentals

The CPU executes instructions and performs calculations, serving as the primary component for processing tasks in a computer.
Key components of CPU architecture include the ALU (Arithmetic Logic Unit), Control Unit, and Cache Memory. The Hard Disk Drive is not part of this architecture.
The CPU's clock speed directly affects how fast it processes instructions, serving as a critical performance metric.

Overclocking and BIOS/UEFI

Overclocking involves running a CPU at a higher clock speed than it is rated for, enhancing performance but potentially causing overheating.
BIOS/UEFI settings are stored in a CMOS battery located on the motherboard, allowing for system configuration.

Memory Types and Functions

Volatile memory like RAM is used temporarily to hold data while a computer is operational, contrasting with non-volatile memory types such as ROM.
Cache memory serves as a fast, temporary storage medium between the CPU and RAM, speeding up access to frequently used data.

Storage Devices

Hard Disk Drives (HDD) utilize spinning magnetic disks to read and write data, while Solid-State Drives (SSD) are known for their faster access and transfer speeds.
SSDs offer superior performance compared to HDDs, despite generally having less storage capacity and being more expensive.

Motherboard and Chipset

The motherboard's chipset controls data flow between the CPU, RAM, and other components, playing a crucial role in overall system performance.
Power supply units (PSU) convert electrical energy into the appropriate voltage and current needed for computer components.

Networking and Connectivity

Network Interface Cards (NIC) connect computers to networks, facilitating communication between devices.
Ethernet ports are primarily used for wired network connections, while monitors typically connect through HDMI or other display ports.

Expansion Cards

Graphics cards enhance a computer's ability to render high-quality graphics and are essential for gaming and design tasks.
Sound cards improve audio input/output quality, providing better sound experience for users.

Power and Storage Expansion

A 24-pin ATX connector supplies power to a motherboard, ensuring proper voltage for operation.
Flash drives are portable USB storage devices, making data transfer convenient and accessible.
