3. Write the function of CPU in short.
The main function of CPU in the computer is to
store and process by performing all the
mathematical and logical calculations with the
input data to provide the output data to the users,
thereby working on the computer.
The function of CPU in 4 Steps:
1. The CPU receives the data when the
computer inputs the data through input
devices such as a keyboard or mouse.
2. After this, the CPU process these input
data by performing calculations and
technical algorithm.
3. And then CPU provides the processed data
through output devices such as on
the monitor screen.
4. The CPU also stores the process data in the
form of a cache for future use.
How CPU (Central Processing Unit) Works?
Since creation and development, improvement of
the CPU, Fetch, Decode and Execute are the
fundamental functions of the CPU.
1. Fetching
As the word suggests, the first CPU receives
the instruction. That means the series of
binary numbers that are passed from RAM to
CPU.

Once the instruction is loaded into the CPU, it
needs to work out what the instruction means.
After which the process of decode begins with
the help of ALU (Arithmetic Logic Unit).
3. Executing
At last, decoded instructions are executed.
Finally, the computer has to carry out the
instruction during the execution step. This
could be many things, including loading data
from memory, storing data in memory, or
performing a calculation.
4. Explain Cookies and Trojan horse, CAD and
CAL.
 Cookies: HTTP cookies are small blocks of
data created by a web server while a user is
browsing a website and placed on the user's
computer or other device by the user's web
browser. Cookies are placed on the device
used to access a website, and more than one
cookie may be placed on a user's device
during a session.
 Trojan horse: A Trojan horse is any malware
that misleads users of its true intent.
Typically, the Trojan horse is hidden in an
innocent-looking email attachment or free
download. When the user clicks on the email
attachment or downloads the free program,
the malware that is hidden inside is
transferred to the user's computing device.
Once inside, the malicious code can execute
whatever task the attacker designed it to carry
out.
 CAD: Computer-aided design is the use of
computers to aid in the creation, modification,
analysis, or optimization of a design. This
software is used to increase the productivity
of the designer, improve the quality of design,
improve communications through
documentation, and to create a database for
manufacturing.
 CAL: Computer Aided Learning is an
integrative technology, which describes an
educational environment where a computer
program is used to assist the user in learning a
particular subject.
5. What is database? What is the use of database
in office administration?
A database is an organized collection of data, so
that it can be easily accessed and managed. You
can organize data into tables, rows, columns, and
index it to make it easier to find relevant
information.
Data are used by different people in different
departments for different reasons. Therefore, data
management must address the concept of shared
data. The DBMS facilitates:
 Interpretation and presentation of data in
useful formats by transforming raw data
into information.
 Distribution of data and information to the
right people at the right time.
 Data preservation and monitoring the data
usage for adequate periods of time.
 Control over data duplication and use, both
internally and externally.
6. Let your computer is connected to internet
through Ethernet. At some point, you have
found that there is no internet available in your
computer. How will you identify where the
problem occurs?
 The most basic thing to do is to check if the
Ethernet adapter is disabled and enable it:
 If the Ethernet network is enabled, but says
Unidentified network, you need to disable and
re-enable it. This is a very common
occurrence on Windows machines and the
solution is simple – go to Network
Connection, right click the Ethernet network,
click on Disable and then on Enable. It should
now see the wired connection and you should
gain access to the Internet.
 Check if the cable is broken or damaged.
