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.
