Study Notes

Computer Systems

Computers consist of core units: CPU, motherboard, and power supply, with peripherals being any additional connected devices.
Common peripherals include mouse, keyboard, monitor, RAM, DVD-ROM, microphone, webcam, and printer, enhancing computing capabilities.

Types and Categories of Peripherals

Input Devices: Send data to the computer; examples include mice and microphones.
Output Devices: Receive information from the computer; examples include speakers and standard monitors.
Input/Output/Storage Devices: Perform both functions, such as external drives.

Computer Memory

Primary Memory: Consists of RAM (volatile) and ROM (non-volatile) crucial for operation.
Secondary Memory: Includes hard drives and optical media; used for long-term data storage.
SSDs offer high speed, while Hard Disk Drives provide more storage capacity.

Processor Functions

A processor executes calculations and basic instructions passed from the operating system.
CPU and microprocessor are terms often used interchangeably, though they are distinct from the Graphics Processing Unit (GPU).

Threads in Processors

Threads are virtual components that divide CPU cores into multiple virtual cores; dual-core CPUs can have up to four threads.
Application examples include loading processes that utilize separate threads for smooth functioning.

BIOS Access

BIOS can be accessed during boot-up using designated hotkeys.
Process includes turning off the computer, powering it on, and immediately pressing the identified hotkey.

PC Connection Interfaces

USB is the dominant interface for ease of use and compatibility.
Other interfaces include PCIe for internal connections and various video connectors such as VGA and HDMI.

RAID Configurations

RAID 0: Performance-focused, interleaves data across multiple drives but has no failure protection.
RAID 1: Provides fault tolerance by mirroring data on two drives; high reliability but requires double the storage.
RAID 5: Combines speed and fault tolerance by distributing parity across drives; common in reliable setups.
RAID 6: Offers enhanced reliability over RAID 5 through additional parity computations.

GPU Basics

GPUs handle rendering of images, videos, and animations, allowing the CPU to focus on other tasks.
There are integrated (sharing memory with the CPU) and dedicated GPUs, each designed for different performance needs.
