Computer network is defined as set of computer system and hardware devices of computer that are connected together for sharing the resources. It is also termed as data network. It deals with the various topics viz. Cryptographic Security, Client Server Model, Application Layer Protocols, LAN, Wireless and Cellular Network, Packet Switching, Network Management, Protocol Layer and Service Models, Datagram Protocol, and many more.
Computer network is used to connect the users of a computer following the defined parameters. Computers are linked together to create a network via modems or cables. Few functions of the Computer Networks are as follows:
- Enable numerous users to share a single hardware device.
- Permits file sharing over network
- Enable sharing of OS and software on remote systems.
- Provide ease of communication via instant messaging, email, etc.
- Multipoint connection
- Point-to-Point connection
OSI model plays an important role. OSI defined as Open System Interconnection and involves the seven main layers.
TCP/IP model is the major concept that involved in the computer network which means Transmission Control Protocol and Internet Protocol. Protocols determine the movement of data between the source and destination. Current internet architecture uses the TCP/IP model also. Various features of this model are listed as:
- Allow users to add machines with network easily.
- Provide support for a flexible architecture.
Moreover, a communication network in which information is transmitted as IR and optical signals is termed as Optical Network. This network transmits information in the form of light pulses by using plastic or glass optical fiber. Most common optical protocol standards which used in optical networking are SONET and Synchronous Digital Hierarchy. Optical networks offer the best transmission capacity as compared to other networks.
The method of blending various available resources into a single virtual network is termed as Network virtualization. It treats all services of the network as a single group of resources. Network virtualization is used to determine the various things such as grid computing, storage virtualization and network management.

Computer network provides effective solution in an enterprise. It facilitates communication through email, conferencing etc. and enables multiple users to share a single device. It allows sharing of software on remote systems by making information easier to access and maintain among network users. File sharing is another characteristic of this network.
A computer network is a connected series of various computer systems which are also termed as nodes of a network. They can be connected via cabling or wirelessly. In this way, it becomes a multipurpose connection which shares resources like file servers, printers and access to internet.
Topology is a way to connect computers in a network which makes a perfect computer network. Various protocols and network languages supports different type of networks. Some of the topologies are given below:
- BUS Topology
- RING Topology
- STAR Topology
- MESH Topology
- TREE Topology
- HYBRID Topology
