Need for Networking
Networking the computers is becoming a basic need of today’s world. Some of the main reasons
to connect the devices into networking are:
Sharing of Resources: The primary goal of computer networking is to share resources, such
as printers, scanners, modems, etc. This enables efficient use of resources and reduces the
need for duplicate equipment or software. For example, several PCs can be connected to a
single printer.
Communication: Networking facilitates communication between individuals and groups
through email, instant messaging, video conferencing, and other communication tools. This
promotes real-time interaction, and enables remote collaboration among geographically
dispersed teams.
Cost Effective: Individually licenced copies of many popular software programs can be costly.
Storing the software on a file server and then making it available to the other computers
connected to it will be cost-effective.
Security: Implementing security measures such as firewalls, encryption, and access controls is
essential for protecting data, systems, and networks from unauthorised access, attacks, and
breaches. Centralised security management and monitoring can effectively shield the data
away from online threats.
DIFFERENT TYPES OF NETWORKS
There are different kinds of computer networks that work in different ways. Networks can be
as small as a home or office network, connecting a few devices, or as large as the Internet,
which connects millions of devices all across the globe. Connections between computers on the
network can be either wired or wireless.
Some of the common types of networks are:
Personal Area Network (PAN): A PAN is a network that connects devices within the personal
range of an individual, such as smartphones, tablets, laptops, and wearable devices. Bluetooth
and infrared are common technologies used for PANs.
