A computer network is a collection of independent computers that are connected to one another. Computers are seen as networked if they can share data. A physical link is established using cables, lasers, microwaves, fibre optics, and communication satellites.

What exactly do we understand by the word “autonomous”? Any network computer that is autonomous cannot compel another network computer to start, stop, or control itself. In other words, the computer works independently. Compared to a computer that has complete control over a sizable number of slaves, this is significantly different. This is not a computer network.
“Distributed computing” is a novel phrase that is strongly tied to networks. A user cannot see that there are several independent computers present in a distributed computer system, which is one way it differs from a computer network. The user can enter commands that the operating system will execute on a different machine. The task of the operating system is to select a free processor, find and transfer all required input files to that processor, and finally communicate the finished product to the user.

What is computer networking?
A network of connected computers that can communicate and share resources is known as a computer network. These networked devices use a set of rules called communications protocols to transmit data through wireless or physical technologies.
How does a computer network work?
Nodes and connections are the basic building blocks of computer networking. A network node could be data communication equipment (DCE), which comprises a modem, hub, or switch, or data terminal equipment (DTE), which contains two or more computers and printers. A link is the communication medium used to connect two nodes. Links can be physically present, such as cable wires or optical fibres, or they might be empty areas that wireless networks use.
Nodes in a working computer network adhere to the rules or protocols that outline how to transmit and receive electronic data over the links. The computer network architecture dictates the designs of these logical and physical components. It provides the standards for the network’s operating structure, physical components, protocols, and practises.
Objectives of Computer Network
Since the introduction of computer automation, computers have developed in every department. A few examples of tasks are managing cash and monitoring inventories and productivity. Initially, this computer is utilised to separate itself from other computers in the division. These provided the crucial computer assistance needed for the duties associated to the relevant department. The departments couldn’t communicate with one another. Therefore, the information was repeated everywhere it was needed. This added redundancy decreased data consistency and consumed more storage space.
In order to collect data and correlate information about the entire firm, it was ultimately agreed to link the computers in various departments. The following is a list of computer networks’ objectives.
- The purpose of a computer network is resource sharing. All network users should be able to access all software, data, and hardware, regardless of where those users and resources are physically located.
- High reliability is the second objective. In case of non-availability (due to hardware failure), the other copies of the files might be used because the files have been duplicated on two or more machines.
- Cost savings have been made possible by the computer configuration. Compared to large computers like mainframes, tiny computers offer a far superior price to performance ratio. Mainframe computers are around 10 times faster than microcomputers, but being thousands of times more expensive. Organizations have chosen to deploy linked microcomputers that are connected to mainframe computers as a result of this imbalance.
- Computer networks have made it possible to increase system performance as the workload increases (load balancing). When a mainframe was fully utilised, it was typically replaced with another huge mainframe computer at the expense of the user.
- Computers allow individuals who reside or work in various areas to collaborate on reports. As a result, when a user writes some documentation, he can upload it online and make it available for others to examine and comment on. As a result, computer networks are useful tools for communication.
- The resources of a computer network can only be accessed by authorised users. Users are verified using their user names and passwords. As a result, it is impossible to view the data without a working account. This raises the bar for safety.
