Study Notes

Computer Operations

Four fundamental operations: Input, Processing, Storage, and Output.
Input: Data entry into the computer system.
Processing: Execution of instructions from programs using the CPU.
Storage: Retaining data for future access, involving RAM and hard drives.
Output: Delivery of processed data to users through displays, printers, etc.

CPU

Central Processing Unit (CPU) functions as the computer's "brain."
Executes computer program instructions via arithmetic, logical, control, and I/O operations.
Faster CPUs directly correlate with quicker execution times for tasks.

Upgrading PC Specifications

Upgrade feasibility varies based on computer design and components.
Desktop computers tend to have higher upgrade potential compared to laptops.

GPU

Graphics Processing Unit (GPU) handles rendering and displaying images, videos, and animations.
Essential for gaming, video editing, and other graphics-intensive applications.

Computer Operations

Computer operations consist of four main functions: input, processing, storage, and output.

CPU

The Central Processing Unit (CPU) acts as the brain of the computer, executing program instructions.
It performs essential operations:
- Arithmetic: Basic mathematical calculations.
- Logical: Decision-making operations (e.g., comparisons).
- Control: Directing the sequence of operations.
- Input/Output: Handling communication with external devices.
Performance is largely dependent on CPU speed; a faster CPU results in quicker program execution.

Upgrading a PC

Upgrading a PC varies by its design and components; some systems allow for easier modifications than others.
Desktop computers generally provide greater flexibility for future upgrades compared to laptops.

GPU

The Graphics Processing Unit (GPU), or Graphics Card, is critical for rendering graphics, videos, and animations on a display.
It enhances visual performance, making it vital for gaming and graphic design applications.
