6.1.1 - Identify the resources that need to be managed within a computer system. Flashcards
What is primary memory (RAM) and why is it important in a computer system?
Primary memory (RAM) is where data and programs are stored while running. If RAM is too limited, the system will rely on virtual memory more, affecting multitasking and program loading.
What is secondary storage and what happens if it’s too limited?
Secondary storage stores data when power is lost. If it is too limited, there is no place to save data, which could cause data loss and prevent the OS from using storage for virtual memory.
How does the processor’s speed and number of cores affect system performance?
A slower processor takes longer to perform tasks, while fewer cores limit the number of tasks done simultaneously, affecting multitasking and task completion times.
What is bandwidth and how does it affect data transmission in a system?
Bandwidth measures how much data can be sent at the same time. If bandwidth is too limited, data takes longer to move between points, delaying processing.
How does screen resolution affect a system’s display?
Screen resolution determines the number of pixels displayed. A low resolution leads to poor image quality and pixelated displays, although it reduces file size.
What is a sound processor and why is it important?
A sound processor handles sound reproduction, freeing up the CPU. Without one, the CPU must process sounds, slowing the system and reducing audio quality.
What is a graphics processor (GPU), and how does it affect system performance?
A GPU performs complex graphic tasks like 3D rendering. If the CPU has to handle graphics processing, it can slow down performance significantly.
What is cache, and how does it impact processing speed?
Cache stores instructions or data that the CPU is likely to request next from RAM. If too limited, the CPU has to wait for instructions, slowing down the system.
How does network connectivity affect system functionality?
Network connectivity allows a system to send and receive data. Limited connectivity options or speeds reduce how data can be transmitted and received.
