Study Notes
Computer System Suitability Evaluation
- System Specifications: A set of requirements for a device, either hardware or software. Includes processing speed, memory, storage, software, and input/output. Crucial to check compatibility before purchase.
-
CPU (Central Processing Unit): The "brain" of the computer, responsible for data processing.
- CPU Speed: Measures how fast instructions are executed (Hertz, MHz, GHz); faster clock speeds allow more instructions per second.
- CPU Type: Determines suitability for specific applications; major manufacturers (Intel, AMD) produce various processor types. Intel processors often more expensive but potentially less heat-producing compared to AMD.
Memory (RAM)
- Memory Capacity: Measured in Gigabytes (GB). Larger capacity means more programs can operate simultaneously. Most modern PCs have at least 2GB.
- Memory Type: SDRAM (Synchronous Dynamic RAM) is common, DDR (Double Data Rate) SDRAM being a faster variation. RDRAM, used in high-performance systems, is faster but more expensive.
- Word Size: Most PCs have 32-bit or 64-bit word sizes, determining the amount of data the CPU can process at once.
- Memory Speed: Measured in MHz, indicates how quickly the processor accesses memory. Most modern PCs have at least 400 MHz.
Secondary Storage (Hard Drive)
- Storage Capacity: Measured in Gigabytes (GB) and Terabytes (TB). More space means larger information storage. Modern PC hard drives range from 120GB to 2TB.
- Speed: Measured in Revolutions Per Minute (RPM); faster drives transfer data quicker.
Software
- System requirements: Consider software compatibility; check if the software needs specific performance capabilities from the hardware.
Input/Output Devices
- Various input/output devices affect use cases. Consider the specific needs of the task, i.e., graphic design or video editing.
Overall Suitability Evaluation
- Evaluate system specifications against the intended computer task's demands. Assess processing speed, memory, storage capacity and other requirements for each task. Compare different hardware specifications based on task requirements.
