Computer network is a collection of computing devices that are connected in different manners in order to communicate and share resources. The connections between computers in a network are made using physical wires or cables or through wireless, using radio waves, microwaves, satellite or infrared signals. The term node or host refers to any device on a network, the data transfer rate is the speed with which data is moved from one place on a network to another. Computer networks have opened up a new field in the world of computing called the client/server model.
File server is a computer that stores and manages files for multiple users on a network while web server is a computer dedicated to responding to requests (from the browser client) for web pages. The IIMT University, Meerut is rated among the best private university in Delhi-NCR providing free Wi-Fi services to the students and staff for research and innovation. We can divide the network into three types Local-area network (LAN), Metropolitan area network (MAN) and Wide area network (WAN). A network that connects a relatively small number of machines in a relatively close geographical area is called LAN.
A network that connects a large number of machines throughout the world is called WAN. A network that connects more numbers of machines than LAN and covers a area within a city/cities is called MAN. There are different configurations, called topologies, have been used to administer network. Ring topology is a configuration that connects all nodes in a closed loop on which messages travel in one direction, Star topology is a configuration that centers around one node to which all others are connected and through which all messages are sent, bus topology in which all nodes are connected to a single communication line that carries messages in both directions.
No single person or company owns the Internet or even controls it entirely. As a wide-area network, it is made up of many smaller networks. These smaller networks are often owned and managed by a person or organization. The Internet, then, is really defined by how connections can be made between these networks. The IIMT University, Meerut is rated among the best private university in Delhi NCR is providing best hostel accommodation to its students and staff inside the campus.
