Study Notes
Computer Components and Systems
-
Processor (CPU): The "brain" of the computer; it interprets and executes instructions from hardware and software, receiving input, processing it, and providing output.
-
Arithmetic Logic Unit (ALU): Performs mathematical and logical operations (addition, subtraction, comparisons).
-
Control Unit (CU): Reads and interprets instructions, manages data flow, and coordinates other parts to ensure tasks are executed correctly.
-
Memory (RAM): The computer's immediate memory, holding data the processor is actively using. It is volatile (data lost when the computer turns off). More RAM allows for better multitasking.
-
Storage (Secondary Memory): Long-term data storage, retaining information even when the computer is off. Includes:
- Hard Disk Drives (HDDs): Traditional storage with spinning disks; cost-effective but slower.
- Solid State Drives (SSDs): Faster and more reliable than HDDs, using flash memory; more expensive but faster.
- External Drives: HDD or SSD connected externally, useful for backups and file transfers.
- Memory Cards/USB Drives: Compact for moving and sharing files.
Hardware and Software Selection
-
Functionality: Consider the tasks you need to perform to select appropriate hardware and software. Gamers need powerful processors and graphics cards; graphic designers need high-resolution screens and design programs.
-
Cost: Set a budget. High-end hardware (like new processors) and some software can be expensive.
- Hardware cost variations: Prices differ significantly between components. Top-tier parts are more expensive but offer more performance.
-
Speed: Important for how quickly the computer starts up, loads programs, and processes tasks. Speed is tied to the processor, RAM, and storage type. SSDs are significantly faster than HDDs.
- Software speed considerations: Software can vary in speed based on its programming and resource demands. Some software performs well on less powerful computers; others require more power.
-
Durability: Quality hardware and well-maintained software ensures reliable performance over time. SSDs are more durable than HDDs due to no moving parts.
