The hardware components and structure,wires and other elements that contains the room IT7 within the building of CICT,and the software,protocols and the data travel along the wires are the combination known as Local Area Network or LAN.
The following is a list and brief description of the standards and cabling components for the room IT7.
Standards
The EIA/TIA (Telecommunications Industries Association) wiring standards provide guidelines for the network wiring of buildings.The Electronic Industries Alliance (EIA, until 1997 Electronic Industries Association) is a trade organization composed as an alliance of trade associations for electronics manufacturers in the United States. Those associations in turn govern sectors of EIA standards activity.An organization that sets standards for technology industries. TIA (Telecommunications Industries Association) represents providers of communications and information technology products and services for the global marketplace through its core competencies in standards development, domestic and international advocacy, market development and trade promotion programs. The association makes possible the convergence of new communications networks while working for a competitive and innovative market environment. TIA strives to further its 700 members' business opportunities and to promote economic growth and the betterment of humanity through improved communications.
Topology
Star networks are one of the most common computer network topologies. In its simplest form, a star network consists of one central switch, hub or computer, which acts as a conduit to transmit messages. Thus, the hub and leaf nodes, and the transmission lines between them, form a graph with the topology of a star. If the central node is passive, the originating node must be able to tolerate the reception of an echo of its own transmission, delayed by the two-way transmission time (i.e. to and from the central node) plus any delay generated in the central node. An active star network has an active central node that usually has the means to prevent echo-related problems.
The star topology reduces the chance of network failure by connecting all of the systems to a central node. When applied to a bus-based network, this central hub rebroadcasts all transmissions received from any peripheral node to all peripheral nodes on the network, sometimes including the originating node. All peripheral nodes may thus communicate with all others by transmitting to, and receiving from, the central node only. The failure of a transmission line linking any peripheral node to the central node will result in the isolation of that peripheral node from all others, but the rest of the systems will be unaffected.
Passing of Data Packet through unnecessary nodes is prevented by this topology. At most 3 devices and 2 links are involved in any communication between any two devices which are part of this topology. This topology induces a huge overhead on the central hub, however if the central hub has adequate capacity, then very high network utilization by one device in the network does not affect the other devices in the network.
Telecommunications Closet
Telecommunication closet will be located near the center of the CICT bulding.Also known as wiring closet.One on each floor (typically, depending on the floor space and special requirements number may vary).Standards complaint connecting hardware should be used.Specifications about short cables (patch chords) are made.In large office buildings, there will be centralized equipment rooms to house servers, hubs, modems etc.It is the central interconnection point for network cabling.Main cross connections are specified here.

Categories of Wire
There are several categories of wire recognized in the EIA/TIA standards. Category 6 wire - four-pair, unshielded twisted pair (UTP) - is the cable of choice because of its 1000 Mbps capability. The network software and hardware other than the cables will determine the actual network speed.
Electrical wiring in general refers to insulated conductors used to carry electricity and associated devices. This article describes general aspects of electrical wiring as used to provide power in buildings and structures, commonly referred to as building wiring. This article is intended to describe common features of electrical wiring that should apply worldwide.
Connectors
All wire cable connectors (jacks and plugs) in the room IT7 Lan installation should be RJ-45 Category 6 connectors.Although used for a variety of purposes, the RJ-45 connector is probably most commonly used for 10Base-T and 100Base-TX Ethernet connections.
