History and Etymology for telecommunication International Scientific Vocabulary. Learn More About telecommunication. Every telecommunications network typically consists of three main network components: a data plane, a control plane, and a management plane. The core of all network design consists of seven layers: Physical, Data link, Network, Transport, Session, Presentation, and Application layer.

Gateways such as routers and bridges help solve the problem. Interconnection between two networks of the same type is accomplished by a relatively simple bridge , implemented in hardware and software. A router is a device that accepts messages in the format produced by one of the networks and translates them into the format used by the other. Organizations small and large use fast local area networks LANs to interconnect personal computers, and thus make a basic workgroup tool.

Local Area Network: Workplace for a Workgroup. A LAN interconnects computers within a single site, such as an office building, a manufacturing plan, or a corporate or university campus. Characteristics of a LAN include:.

Its scope is commonly measured in feet. Communication speeds are very high. Used as a local means of computing and communication among users in larger firms.

Are owned by the organization. Afford a sense of control and the flexibility to meet the demands of the end users. A LAN gives its users the following capabilities:. Users can share resources, such as a fast printer or a database. Users can collaborate by communicating over their LAN. This collaboration may be facilitated by groupware that runs on a LAN.

Users can access other networks within a firm or outside of it via bridges and routers. There are two principal LAN designs :. Peer-to-peer - peripherals are located at terminals and system administration is largely left up to the users. Server-based networks - shared resources are placed a dedicated server that manage a given resource on behalf of user workstations sharing the resource file server, printer server, gateway, optical disk server.

Most of the servers are dedicated to their task; using them as workstations degrades the performance of the net. A company with a large number of telephones from 50 to over 10, often elects to own a computer-based private branch exchange PBX , an electronic switchboard that interconnects its telephones and provides connections to the public network.

Characteristics of a PBX:. Gives a company control over the usage of its telephone system and offers a variety of features, such as call forwarding or voice messaging. Maybe employed as a switch for data communications. Many newer PBXs use digital technology, eliminating the need for modems, and perform conversions needed to ensure connectivity between various equipment and telecommunications links.

Easy to connect a new workstation to the net. Speeds of PBX-based networks are limited. An important current development in organizational computing is downsizing - moving from platforms based on mainframes and minicomputers to a microcomputing environment.

The processing of a given application is split up among a number of clients - serving individual users - and one or more servers - providing access to databases and doing most of the computing.

Main objective of a client is to provide a graphical user interface to a user. Main objective of a server is to provide shared services to clients. Two-Tier Architecture. Three-Tier Architecture. Characteristics of Two-Tier Architecture: [Figure 7. Client performs presentation services. It displays the GUI and runs the program that determines what happens when the user selects a menu option.

Server manages the accesses to the database. Clients send remote procedure calls to activate specific applications logic on a server. Characteristics of Three-Tier Architecture: [Figure 7. An application server runs most of the application logic, with the user workstation responsible for the display at the front end and the database server providing database servers at the back end. Objective is to distribute application so as to reduce the overall hardware costs while minimizing the network traffic.

Is attractive in terms of their acquisition price as related to their performance. Is moving computing control out of the data centers and into the end-user areas. Software is complex, and is expensive to maintain.

Generate significant traffic on the firm's backbone network that connects clients and servers. Wide area networks are the fundamental infrastructure of organizational computing.

These long-distance telecommunications networks employ a variety of equipment so that the expensive links may be used effectively. The offerings of common carriers and of providers of value-added services may be combined with private networks to create an overall organizational network. WANs include equipment that controls message transfer and makes it possible to share the links among a number of transfers.

A WAN has a powerful host computer. The host runs a system program, called a telecommunications monitor, which processes incoming messages, passing them to the appropriate application programs, and accepts outgoing messages from the applications in order to transmit them into the network. Front-End Processor. Relieves the host computer of most of the tasks involved in network control. Under the control of its own software, the front-end processor accepts messages coming from the network and routes outgoing messages to their destinations.

It performs the necessary code conversions, encrypts and decrypts secure messages, and performs error checking so that the host deals with Aclean messages. Cluster Controller. Manages several terminals, connecting them to a single telecommunications link, and performs communication tasks for them, such as screen formatting, code conversion, and error checking.

A cluster controller may also allow the terminals to share a high-speed printer and may handle electronic mail among the cluster terminals. Combines the data that terminals send to it over local low-speed links into a single stream. This stream is then transmitted over a high-speed telecommunications channel and is split by another multiplexor on the opposite end of the channel. Combines transmission from several slower terminals that operate in a burst mode into a single transmission stream that requires a link of lower speed than the sum of the speeds of all the terminals combined.

A concentrator stores messages from terminals and forwards them when warranted. Establishes connections between nodes that need to communicate. Include a variety of dumb terminals, with no processing capacity and intelligent terminals with processing capacity, such as personal computers.

Some network facilities are owned by user organizations, others can be leased by them, or simply used on a pay-as-you-go basis. Among the typical facilities owned by user firms are workstations, host computers, and front-end processors. The essential providers of telecommunications links and services are common carriers and the vendors of enhanced services on value-added networks.

These include:. Providers of value-added networks. Private lines and private networks. Are companies licensed by a country's government to provide telecommunications services to the public. The vast majority of common carriers provide telephone service. These carriers offer the use of a wide-area telecommunications infrastructure, that is, facilities for the transmission of voice and data messages. Common carriers offer a service called virtual private network where a user firm can purchase guaranteed access to facilities with specified capabilities, such as transmission speed and access points.
