Study Notes

Input and Output Devices

Input devices transmit data to the computer and are one-way, such as a mouse and microphone, which send cursor movement and audio data respectively.
Output devices receive data from the computer and do not send data back, including speakers that output sound and standard monitors that display information.
Touchscreen monitors can function as both input and output devices.

Memory Types

Computer memory is crucial for operations and is classified into primary (RAM and ROM) and secondary memory (e.g., hard drive, CD).
Random Access Memory (RAM) is volatile (data cleared when power off), while Read-Only Memory (ROM) is non-volatile (retains data).

Accessing BIOS

BIOS can be accessed using specific hotkeys during boot-up, such as F1, F2, F10, F12, or DEL, depending on the manufacturer.
For Windows 10, access BIOS through advanced start menu settings if startup is too quick.
Older systems may require pressing hotkeys before the Windows logo appears.

Connection Interfaces

USB is the predominant PC connection interface due to compatibility and user-friendliness.
PCIe (PCI Express) serves as an internal bus for fast communication.
Various external connections include IEEE 1394, eSATA, HDMI, and VGA.
NFC technology allows passive devices to transmit data without power; active NFC devices can send and receive data.

Serial and Parallel Interfaces

SATA (Serial Advanced Technology Attachment) enables faster data transfer between motherboard and storage compared to PATA (Parallel ATA), providing higher speeds and reduced interference.

Bluetooth Device Pairing

To pair a Bluetooth device, it must be turned on and discoverable.
Follow the path: Start > Settings > Bluetooth & devices > Add device > Bluetooth, then follow on-screen instructions.

RAID (Redundant Array of Independent Disks)

RAID enhances performance and provides fault tolerance using two or more drives.
RAID 0 uses striping for performance; however, it lacks failure safeguards.
RAID 1 mirrors data across drives for high reliability, requiring double the number of drives.
RAID 5 stripes data with distributed parity for speed and fault tolerance, while RAID 6 offers greater reliability with additional parity computation.
RAID 10 combines features of RAID 1 and RAID 0 for optimal safety and performance.

GPU Basics

GPUs (Graphics Processing Units) are essential for rendering graphics and animations in PCs.
Integrated GPUs share memory with the CPU, whereas discrete GPUs have their own dedicated memory (VRAM).
GPU capabilities extend beyond gaming into fields like AI, content creation, and high-performance computing, where they accelerate 3D graphics rendering and complex computations.

Machine Language

Machine language is a low-level binary code that computers can directly understand, also called machine code or object code.
All programming languages, including Swift and C++, ultimately compile into machine language for execution on a computer.
