Study Notes

Smartphone Applications and Threads

Smartphone apps utilize threads for efficient operation, with one thread managing the loading spinner and another rendering the graphical user interface (GUI).
The number of threads a CPU can support varies by physical CPU model, impacting app performance.
Threads enable multitasking, allowing users to perform concurrent operations like browsing the web while listening to music.

BIOS Configuration

BIOS (Basic Input/Output System) is firmware stored in nonvolatile memory (ROM/flash) and is the first program executed upon powering a computer.
BIOS performs hardware identification, configuration, testing, and connection to the operating system through a process known as booting.
Key functions of BIOS include Power-On Self-Test (POST).

Bluetooth Device Pairing Procedure

Ensure Bluetooth device is powered on and discoverable according to its manufacturer's instructions.
On a Windows PC, navigate to Settings > Bluetooth & devices > Add device > Bluetooth to initiate pairing.
Follow on-screen instructions to complete the pairing; devices typically reconnect automatically when within range.

RAID (Redundant Array of Independent Disks)

RAID encompasses disk subsystems that enhance performance and fault tolerance using multiple drives and a RAID controller.
RAID configurations can be hardware-based (using controllers) or software-based (less common due to speed limitations).
Common RAID types:
- RAID 0: Performance-driven striping with no redundancy.
- RAID 1: Mirroring for fault tolerance, requiring twice the number of drives.
- RAID 3 & 4: Striped data across multiple drives, using parity for data protection.
- RAID 5: Combines speed and fault tolerance with distributed parity.
- RAID 6: Similar to RAID 5 but offers enhanced reliability with additional parity computations.

GPU Basics

Graphics Processing Units (GPUs) are essential for rendering images, video, and animations in computing.
Two types of GPUs exist:
- Integrated GPUs: Built into the CPU, sharing memory with it.
- Discrete GPUs: Standalone cards with dedicated video memory (VRAM).
GPUs excel in parallel processing, beneficial for gaming, content creation, and AI applications.

Machine Language

Machine language is a low-level language consisting of binary numbers, representing the only language understood by computers.
Commonly referred to as machine code or object code, it forms the basis for all programming languages, like Swift and C++.
Programs in higher-level languages are translated into machine language before execution.

Compilation Process

Compiler: A program that translates high-level source code into machine code, bytecode, or other programming languages.
Translates entire code at once, creating tokens and checking semantics before execution.
May require multiple passes and can accumulate errors through the process.

Interpreters vs Compilers

An interpreter translates high-level language into machine language, processing code statement by statement.
Unlike compilers, interpreters halt execution upon encountering errors, reporting them immediately.

Assemblers

An assembler converts assembly language into machine code, producing an object file with machine instructions for execution.
Facilitates software and application development by allowing interaction with computer hardware architecture.
