This document provides an overview of microprocessors including their definition, importance, components, registers, types, and applications. A microprocessor is an integrated circuit capable of carrying out computer program instructions by receiving, interpreting, and executing actions. It is important because it allows devices to have many functions by communicating with other parts like displays. A microprocessor contains millions of transistors on a small silicon chip and includes components like a control unit, arithmetic logic unit, and registers for temporary storage. Common types include PowerPC and Alpha. Microprocessors are used in general applications like personal computers as well as special applications like instrumentation, control systems, and communication devices.

3. What is a Microprocessor?
• Microprocessors are integrated electrical
circuits that are capable of carrying out the
instructions of a computer software
application or program. These electrical
circuits receive instructions from the
application or program, interpret these
instructions and execute an action or set of
actions, based upon what the instructions
call for.

5. Why Is a Microprocessor Important?
A device that uses a microprocessor is normally •
capable of many functions, such as word
processing, calculation, and communication via
Internet or telephone. However, for the device to
work properly, the microprocessor itself has to
communicate with other parts of the device. For
example, a microprocessor would need to
communicate with the video display to control the
output data that a program may produce.
Therefore, a microprocessor would act as device's
"brain" in that it transmits, receives and interprets
the data needed to operate a device.

• CPU etched on a chip
• Chip size is ¼ x ¼ inch
• Composed of silicon
• Contains millions of transistors
– Electronic switches that can allow
current to pass through
9. How many microprocessor in the
computer?
PCs have dual-core central processors •
(CPU). That's one chip with two complete
microprocessors on it, both sharing one
path to memory and peripherals.
