The goals of computer network are:
- Communication:
The main goal of computer networking is to enable communication between
different devices. This allows users to share information and collaborate
with one another, regardless of their physical location.
- Resource-sharing:
Computer networks also make it possible to share resources such as
printers, storage devices, and applications. This allows multiple users to
access and utilize the same resources, increasing efficiency and reducing
costs.
- Connectivity:
Networking also allows devices to connect to the internet, which provides
access to vast amount of information and resources. This includes being
able to connect to other computers and networks, access remote servers and
cloud services, and use internet-based applications and services.
- Security:
With the increase in connectivity, securing the network and the data that
travels through it is increasingly important. Firewalls, intrusion
detection systems, and other security measures are used to protect
networks from unauthorized access and attacks.
- Scalability:
Another goal of networking is to design the network in such a way that it
can grow and adapt to changing needs and requirements. This includes the
ability to add new devices and users, and to upgrade hardware and software
as necessary.
- High
availability: Many organizations depend on the network for their day to
day operations, so high availability is also a key goal for many networks.
This can include features such as failover and redundancy, to ensure that
the network remains available even in case of hardware or software
failure.
