Module 4: The Central Processing Unit
(CPU) Question and answers correctly
solved 2025
This is the component that does the computer's main work of accepting data
and converting it to information. The processor carries out the instructions of a
computer program. It is often referred to as the "chip." The CPU (or processor)
consists of - correct answer two parts: the control unit (CU) and the arithmetic
logic unit (ALU).
The control unit does as its name indicates— - correct answer it retrieves the
instructions and the raw data that is input, and coordinates or controls the
sending of those instructions and data to the ALU.
The ALU does - correct answer the actual processing of the data, from
mathematical calculations and logical operations (comparing values that can
be numeric or alphabetical) to conversion of keyboard text entry to output
display on your screen. Most PCs now come with multiple CPUs installed to
increase the speed at which the data can be converted to information.
When multiple CPUs are included together - correct answer the processing
unit is referred to as a multi-core processor. Today's PCs often come with
quad-core processing units. Contemporary PCs typically include multiple
CPUs (2, 4, or even 6 or more) to increase the processing speed.
The system clock is another important component related to the CPU. The
system clock controls the speed at which instructions are processed.
Processing speed is listed in terms of megahertz (MHz, millions of processes
per second) or gigahertz (GHz, billions of processes per second), although
today's PCs have processing speeds in GHz only. The GHz rating and
number of processors working simultaneously in the CPU influence - correct
answer the processing speed. For example, having multiple processors
