Module 4. The Central Processing Unit
(CPU)
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 -
answertwo parts: the control unit (CU) and the arithmetic logic unit (ALU).
The control unit does as its name indicates— - answerit 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 - answerthe 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 - answerthe 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
- answerthe processing speed. For example, having multiple processors working
simultaneously will increase processing output even with a slower clock speed.
the amount of RAM available to store data as it is being processed can - answeraffect
the responsiveness, as can the wiring of electrical circuits.
Indicate which of the following is an accurate statement about the CPU. - answerThe
CPU interprets and executes programs.
Responsiveness of a PC will rely on all of the following components except: -
answerWhether the CPU has a CU. Because all CPU's have a CU.
