Q.1 Define CPU. What are the three sub units of CPU? Explain each.
Answer: - CPU: - A central processing unit (CPU) (formerly also referred to as a central processor unit is
the hardware within a computer that carries out the instructions of a computer program by performing
the basic arithmetical, logical, and input/output operations of the system. The term has been in use in
the computer industry at least since the early 1960s.The form, design, and implementation of CPUs have
changed over the course of their history, but their fundamental operation remains much the same.
A computer can have more
Q.2 Differentiate between integrated Circuits and microprocessors.
Answer:- The Integrated Circuit (also known as IC, chip or microchip) placed the previously separated
Transistors, resistors, capacitors and wiring circuitry onto a single chip made of semiconductor material
(either Silicon or Germanium). The Integrated Circuit greatly shrunk the size and cost of making
electronics and impacted the future designs of all computers and other electronics.

2. Computers today are dominated by two major microprocessor companies namely Intel and AMD, the
latest offerings of microprocessors available from Intel for example contains billions of transistors and
as a comparison the Intel 4004 chip from 1971
Q.3 What is the significance of Processor mode? Explain three types of processor modes.
Answer: - significance of Processor mode:- Processor modes refer to the various ways that the
processor creates an operating environment for itself. Specifically, the processor mode controls how the
processor sees and manages the system memory and the tasks that use it. There are three different
modes of operation that resulted from the evolution of the PC from its humble beginnings with the Intel
8088 chip.
Real Mode:
Q.4 Explain the features of a mouse and a track ball
Answer: - A trackball is a pointing device consisting of a ball held by a socket containing sensors to
detect a rotation of the ball about two axes—like an upside-down mouse with an exposed protruding
ball. The user rolls the ball with the thumb, fingers, or the palm of the hand to move a pointer.
Compared with a mouse, a trackball has no limits on
Q.5 What is data communication? Explain different Data Transmission methods.
Answer:- Data communication refers to the exchange of data between a source and a receiver. Data
communication is said to be local if communicating devices are in the same building or a similarly
restricted geographical area. The meanings of source and receiver are very simple. The device that
transmits the data is known as source and the device that receives the transmitted data is known as
receiver. Data communication aims at the transfer of data and maintenance of the data during the
process but not the actual generation of the
Q.6 What is an IP address? Describe the classes of IP addresses.
Answer:- An Internet Protocol address (IP address) is a numerical label assigned to each device (e.g.,
computer, printer) participating in a computer network that uses the Internet Protocol for
communication.[1] An IP address serves two principal functions: host or network interface identification
and location addressing. Its role has been characterized as follows: "A name indicates what we seek. An
address indicates where it is. A route indicates how to
