networks in general

Common networking terms and their definitions

Networking: variety of computers (2 or more) coupled along to share resources

Network Interface Card: additionally referred to as Associate in Nursing LAN card, or NIC card. The NIC is maybe the foremost common part of any network. it's the part that gives the association between a computers internal bus and therefore the network media or cabling

Hub: A physical device that is a central association purpose for many network devices. At its simplest level a hub is nothing over a multi-port repeater. The hub can repeat what it receives on one port to all or any its alternative ports.

Routing: A perform of the network that involves moving information through a network. information passes through many network segments mistreatment routers that choose the trail the information takes.

Router: sometimes a physical device that connects 2 networks and permits information to be sent and received between them. A router can verify the simplest path for the information to require from its supply to its destination.

Category five RJ-45 cable: typically referred to as CAT-5 cabling. it's the foremost unremarkably used kind of network cable. it's wont to connect the NIC to a hub, router, and varied alternative network devices.

Network Protocols: Computers and devices on a network need to communicate with one another. A protocol could be a predefined set of rules that dictate however the computers and devices communicate and exchange information over a network.

TCP/IP: this can be a sort of network protocol. It combines the Transmission management Protocol (TCP) and therefore the web Protocol (IP). this can be the protocol most ordinarily utilized in Windows primarily based networks. it's additionally the quality protocol used for communications over the net. it absolutely was originally developed by the Department of Defense.

IP Address: this can be Associate in Nursing address employed by the net Protocol to spot a laptop or device’s location on the network. This variety is typically assigned to a laptop by the net Service supplier (ISP) or by the network administrator.

DHCP: This word form stands for Dynamic Host Configuration Protocol. it's a protocol used on a TCP/IP network to send the shopper configuration information, together with the information processing address, subnet mask, gateway, and DNS configuration, to the computers or purchasers on the network. It essentially mechanically provides configuration information to the computers on a TCP/IP network. employing a DCHP configuration save times by eliminating the requirement to manually assembleevery laptop on the network.

DNS: word form that stands for name Service. it's a service utilized in TCP/IP networks that interprets host names to information processing addresses. the most important use of DNS is that the web itself. ISP’s use what area unit referred to as DNS servers to translate internet addresses to their actual information processing or network addresses. as an example once World Wide Web.winbookcorp.com is accessed by an internet browser, the DNS server can translate the location name to the particular network address.
