IB Computer Science - Topic 6 Latest
Exam Questions And Already Passed
Answers.
Resources to manage - Answer Primary memory
Secondary storage
Processor speed
Bandwidth
Screen resolution
Sound processor
Graphics processor
Network connectivity
Primary memory - Answer Where all data/programs currently being processed are kept
Effect when primary memory is too limited - Answer Need to use secondary memory = slower
Virtual memory problem = can't load data
Secondary storage - Answer permanent storage memory not directly connected to the processor;
also called backing store or auxiliary storage
Effect when secondary storage is too limited - Answer No place to save work
Limits storage amount
Can also prevent the OS from using storage as virtual memory if RAM fills up
Processor speed - Answer The speed, or frequency, (in MHz) at which the Central Processing Unit (CPU)
in a computer operates.
Measured in MIPS or clock rate.
, Effect when processor speed is too limited - Answer Takes longer to perform tasks
Effect of bandwidth is too limited - Answer Movement of data is longer and entirety of data
Bandwidth - Answer The rate at which data travels from Primary memory to the CPU and back.
Expressed in millions of bits per second (Mb/s).
Screen resolution - Answer The number of pixels that make up a display. Expressed using two numbers,
Width x Height.
Effect when screen resolution is too limited - Answer Poorer quality images = harder for user to see
correctly
Sound processor - Answer Facilitates the input, the processing, and output of audio signals.
Today, it is mostly integrated within the motherboard, but can be separate.
Effect when sound processor is too limited - Answer Slows down the overall system;
Sound quality of inputs and outputs suffer.
Graphics processor - Answer Efficiently process and manipulate graphic and image data. Reduces stress
on CPU for these types of tasks.
Effect when graphics processor is too limited - Answer Takes longer to display graphics;
Graphics and images can appear lower quality;
Overall system performance suffers;
Cache - Answer A small high-speed memory in the CPU that holds information that is often used
increasing processing speed
