3. Computer Network
A computer network is a set of devices connected through links. A node can be
computer, printer, or any other device capable of sending or receiving the data.
The links connecting the nodes are known as communication channels.
•Computer Network is a group of computers connected with each other
through wires, optical fibres or optical links so that various devices can interact
with each other through a network.
•The aim of the computer network is the sharing of resources among various
devices.
•In the case of computer network technology, there are several types of
networks that vary from simple to complex level.

4. Components Of Computer Network
Computer network components are the major parts which are needed
to install the software. Some important network components
are NIC, switch, cable, hub, router, and modem. Depending on the type
of network that we need to install, some network components can also
be removed. For example, the wireless network does not require a
cable.

5. NIC
•NIC stands for network interface card.
•NIC is a hardware component used to connect a computer with another
computer onto a network
•It can support a transfer rate of 10,100 to 1000 Mb/s.
•The MAC address or physical address is encoded on the network card chip
which is assigned by the IEEE to identify a network card uniquely. The MAC
address is stored in the PROM (Programmable read-only memory).

6. Graduate Record Examinations
Value of Using GRE Scores
Scores Support Institutions' Efforts to Identify Which Applicants Are
Academically Prepared for Graduate-level Study.
Scores Provide a Common, Objective Measure to Help Programs Compare
Applicants from Different Backgrounds.
Important Considerations
The Scores Do Not and Cannot Offer Insight Into All of the Qualities that Are
Important In Predicting Academic Success or In Confirming Undergraduate
Achievement.
The Scores Need to Be Interpreted Carefully Because, Like All Tests, They Are
Not Exact Measures.
