- The Network Computer (or NC) was a diskless desktop computer device made by Oracle Corporation from about 1996 to 2000. The devices were designed and manufactured by an alliance, which included Sun Microsystems, IBM, and others. The devices were designed with minimum specifications, based on the Network Computer Reference Profile.

Computer networking was influenced by a wide array of technology developments and historical milestones. In the late 1950s, a network of computers was built for the U.S. military Semi-Automatic Ground Environment (SAGE) radar system using the Bell 101 modem. It was the first commercial modem for computers, released by AT&T Corporation in 1958.

One large network of communication technology would be difficult to implement. As a result, we split up various components of the network into smaller modules or layers. The standard model of a network is the Open Systems Interconnection (OSI) model set by the International Organization Standard (ISO). Other network models exist, though they are al...
OSI (Open Systems Interconnection) is a 7-layer network model specified by ISO (International Organization for Standardization) norm and is widely used all around the world. The concept of a seven-layer model was provided by the work of Charles Bachman, Honeywell information Services. Various aspects of OSI design evolved from experiences with the ...
Latency, incorrectly called ping, is a value that measures how much time packets need to travel to their destination. It is measured in miliseconds (ms). The tool that measures latency is called ping, commonly using special ICMPpackets which are smaller than standard data packets so they do not weight the network by their presence. 1. Immediate latency is measured every X seconds and immediately displayed. Its value constantly changes due to the natural properties of packet-switching network...
Capacity is a measure of transfer capacity of a network and is measured in bits per second (bps or b/s), today commonly Mbps or Mb/s. It shows us how many data units are transferred each second. At present, the average bandwidthis far higher than is necessary and it is not a limiting factor in most cases. 1. Uplinkis how much bandwidth is used for transferring data from user to server (usually lower for end users). 2. Downlinkis how much bandwidth is used for transferring data from server to...
Broadcast is a special transmission that is not meant for a single device but is addressed to all devices in specific network. It is mostly used to automatically issue IP addresses to devices by a DHCP server and to create an ARPtable that maps the network and speeds up the traffic.

- Clients and servers
Computer network programming involves writing computer programs that enable processes to communicate with each other across a computer network.
Very generally, most of communications can be divided into connection-oriented, and connectionless. Whether a communication is connection-oriented or connectionless, is defined by the communication protocol, and not by application programming interface. Examples of the connection-oriented protocols include Transmission Control Protocol and Sequence...
For connection-oriented communications, communication parties usually have different roles. One party is usually waiting for incoming connections; this party is usually referred to as "server". Another party is the one which initiates connection; this party is usually referred to as "client". For connectionless communications, one party is usually ...
