Computer Network
Meaning and Types
2
What is a computer network?
A computer network can be defined as a set of
minimum two or more computers related to each
other for sharing sources as well as information.
A simplistic computer network may be constructed
handiest from computer systems while a
complicated computer network can be built from
numerous thousand computer systems.

Different types of network connections
Computer networks can simply be split down
customarily into topologies that are a method of
joining computer systems. There are different
types of computer networking. A collapsed ring is
usually the most commonplace topology today. This
is because of the realization of a network
compact known as the Ethernet. This particular
protocol or we can say compact tends to promote
the Internet, local area networks as well as wide
area networks.

What are network topologies?
Network topology can be understood as the layout
or design of a particular network. It also
represents varying nodes in a network that are
linked to each other and the way they tend to
communicate.

Star topology
A star topology can be defined as a design or
pattern of a network where a central node reaches
a cable to every pc on the network. On this
particular network community, the computer
systems are attached autonomously to the center
of the network. If in case, a cable is damaged,
the counter computer systems can easily perform
without any troubles. A star topology network
tends to require numerous cabling.

Advantages of star topology

• Swift performance with lesser nodes
• Lower network traffic
• Easy enhancement of hub
• Quite simple to troubleshoot
• Easy to setup

Bus topology
A bus topology can be described as another sort
of design wherein a single cable tends to combine
all other computers and the data supposed for the
closing node at the network need to run via each
linked computer. If a cable is damaged, all
computer systems related down the road cannot
attain the network.

Advantages of Bus Topology

• It is quite cost-friendly
• Simply be exercised and utilized in the small
  networks
• Simple to apprehend and understand
• Two cables can be joined together easily

9
Ring Topology
A quite parallel topology is known to be a ring.
In this particular design, the computers are
linked through a single cable only. This concept
in computer science holds a specific value.
However, the culmination nodes are connected to
each other.

Advantages of Ring Topology

• Conveying the network is not impacted with high
  range of
• Quite inexpensive to install as well as extend
