Computer Science - Mock Exam
Solutions
CPU (Central Processing Unit) - ANS-The key component of a computer system, which
contains the circuitry necessary to interpret and execute program instructions
GPU (graphics processing unit) - ANS-Specialized processor that helps the CPU by
taking over all of the 3-D rendering duties.
Random Acces Memory (RAM) - ANS-a type of memory that can be read from and
written to by the processor and other devices. Ram memory is volatile.
ROM - ANS-Computer memory chips containing permanent or semi-permanent data.
Unlike RAM, this is non-volatile; even after you turn off your computer, the contents will
remain.
Pipelining - ANS-A technique that breaks an instruction into smaller steps that can be
overlapped
Solid-state storage (SSD) - ANS-much faster than traditional magnetic storage because
it stores information using nonvolatile electronic circuits
Magnetic Hard Drive - ANS-One of two technologies used by hard drives where data is
