What Is a Computer Network?

A computer network is a collection of interconnected devices, such as computers, servers, printers, and routers, that are linked together to facilitate communication and data sharing. These devices connect through a variety of mediums, including cables, wireless connections, and infrared signals, forming a network of digital connectivity and information sharing.

The primary purpose of a computer network is to allow devices to communicate and share resources with one another. This can include accessing shared files, printers, and internet connectivity. Networks can be interconnected, enabling communication and data sharing between different networks. Additionally, computer networks can be used to provide data backup and ensure system security, among other functions.

The components of a computer network typically include hardware such as network cards, switches, and routers, as well as software such as network protocols and operating systems. There are several types of computer networks, including Local Area Networks (LANs), Wide Area Networks (WANs), Metropolitan Area Networks (MANs), and Wireless Local Area Networks (WLANs), each with its own distinct features and applications.

Functions of Computer Networks

Computer networks serve various essential functions in modern organizations, enabling digital connectivity and enhancing productivity. Below we discuss the primary functions of computer networks:

Data Transmission

One of the primary functions of computer networks is data transmission. Networks enable users to send and receive data seamlessly, facilitating real-time communication and collaboration. With computer networks, individuals can share information, ideas, and resources from anywhere in the world, enhancing connectivity and knowledge sharing.

Resource Sharing

Computer networks enable the sharing of resources such as printers, scanners, and storage devices. Users can access and use these resources, regardless of their physical location, enhancing efficiency and productivity. Resource sharing also promotes cost-effectiveness, as organizations can make better use of their existing assets and avoid duplicating efforts.


Computer networks enable communication between individuals and teams, allowing them to share information and collaborate more effectively. With email, video conferencing, instant messaging, and other communication tools, computer networks facilitate efficient and timely communication, regardless of location.


Security is one of the most critical functions of computer networks. Networks provide a secure platform for storing and exchanging data, protecting it from unauthorized access and theft. With efficient security protocols and firewalls, computer networks ensure data privacy and confidentiality, preventing cyber threats and other security breaches.

Understanding the functions of computer networks is vital for individuals and organizations seeking to harness their full potential. By allowing data transmission, facilitating resource sharing and communication, and enhancing security, computer networks are integral to modern-day operations, allowing for digital connectivity and productivity.

Facilitating Digital Connectivity

Computing networks are crucial in enabling digital connectivity, playing a vital role in allowing users to access resources and share data seamlessly. With this technological ease comes a widespread impact on contemporary societies. The facilitation of digital data exchanges is ubiquitous – everything from email to video conferencing utilizes computer networks. In this section of the guide, we’ll explore the interconnectivity provided by computer networks, their contribution to digital connectivity and the way in which they currently impact modern society.

The connections that computer networks provide are transforming communication across single organizations and even globally. Digital connectivity has become increasingly important in the last few years, and organizations worldwide depend on it to communicate effectively.
