Content Accuracy rating: 5 Although some data is old (since the text is from 2011), the content is accurate. Computer Network • A computer network or data network is a telecommunications network that allows computers to exchange data. One common form of data communications is the Internet. A network's bandwidth is the number of bits that can be transmitted over the network in a certain period of time. List the different types of network devices used in a network. The Basic Fundamental Of Networking Layer The Application layer is the topmost layer of the TCP and IP protocol suite in Networking. Network Topology: The layout arrangement of the different devices in a network. A protocol defines a set of rules that govern how computers talk to each other.Ethernet and Wi-Fi are Data link protocols that are responsible for framing data on the media (cable or wireless).They can be used for carrying higher level protocols (IP etc)..Ethernet and Wi-Fi use a physical level address know as the MAC address which is 48 bits.EUI 64 addresses are MAC addresses with 64 bits will replace MAC addresses on IPV6, 6LoWPAN, ZigBee and other new network protocols. Describe network communication principles like TCP/IP, DNS, and ports. See your article appearing on the GeeksforGeeks main page and help other Geeks. Network performance is measured by bandwidth and latency. These connections allow devices in a network to communicate and share information and resources. Socket: The unique combination of IP address and Port number together are termed as Socket. Other related concepts DNS Server: DNS stands for Domain Name system. Closed system: A system which is not connected to the network and can’t be communicated with. A PC uses parallel data transmission technology to transmit the data between its internal parts while the media that provides connectivity between different PCs uses serial data transmission technology.
