The significance of networks as integral part of the explanation of entrepreneurial accomplishment is widely accredited. Ethernet, wireless LAN, WAN, MAN, ADSL, cable modem and dialup are common access networks, but have significantly diverse characteristics. Fast and accurate taxonomy of access network type can perk up protocol or application performance drastically. In this paper I make a distinction between large and small business enterprises on basis of network structural design. This distinction is introduced as a contingency in the way networks contribute to the capability of the industries to ascertain opportunities, to acquire resources, and to achieve authenticity.
1. INTRODUCTION
The network of an enterprise plays a significant role in the search for latest opportunities and the
quest for resources. In this paper I’m interested in comparing network architecture of two organization and their usage features.
I will research extensively in order to find the best possible network for:
? A small business or a medium sized office
? A large business
2. NETWORK DEFINITION:
Information system executed with a group of interconnected nodes. Computers on a network are called nodes. There are several diverse ways to network computers together. There are numerous types of computer networks, including:
? Local-area networks (LANs): The computers are physically close together (in the same building).
? Wide-area networks (WANs): The computers are farther apart and are linked by telephone lines or radio waves.
3. NETWORK RELATIONSHIP TYPES
The term network relationship refers to two different concepts concerning how one computer utilizes computer resources of another computer over a network.
Two fundamental types of network relationships exist:
? Peer-to-peer
? Client/server
These two types of network association describe the very configuration of a network. For instance, a peer-to-peer network is to a great extent similar to a company run by decentralised management philosophy, where decisions are made locally and resources are managed according to the primarily urgent requirements. A client/server network is further like a company that works on centralised management, where decisions are made in a central site by a rather small group of individuals. Circumstances exist where both peer-to-peer and client/server relationships are suitable and several networks have features of both kinds contained in them.
Both types of networks necessitate a physical network link between the computers and the same network protocols are to be used. There is no differentiation amid the two types of network association at this point. The disparity transpires when you extend the shared network resources around to entire computers on the network or employ a centralised network server(s).
4. NETWORK STRUCTURE IN SMALL ORGANIZATION
LAN: Local Area Network (LAN) is a computer network that spans a reasonably small area. Most LANs are restricted to a sole building or group of buildings. Most LANs connect workstations and personal computers. Each node (individual computer ) in a LAN has its own CPU with which it executes programs, but it also is capable to access data and devices everywhere on the LAN. This means that several users can share high-priced devices, such as laser printers and at the same time data as well. Users can also utilize the LAN to communicate with each other. This distinctive characteristic on a wired LAN offers unbounded bandwidth on the network by allocating a separate broadband connection to be connected to each Complex Broadband Router on the network.
5. NETWORK DESIGN IN LARGE ORGANIZATION:
WAN: Wide Area Network (WAN) is a computer network that envelops a broad area (i.e., every network whose communications links cross metropolitan, regional, or national borders). Or, a network that uses routers and public communications links. Compared with personal area networks (PANs), local area networks (LANs), campus area networks (CANs), or metropolitan area networks (MANs) which are typically restricted to a room, building, campus or specific metropolitan area (e.g., a city) correspondingly. The major and most recognized illustration of a WAN is the Internet.
WANs are built to offer communication key for organisations or people who require exchanging digital information involving two places. The chief function of a WAN is to provide consistent, swift and secure communication among two or more places through small delays and at low costs. WANs facilitate an organisation to have one fundamental network amid all its departments and offices, even if they are not all in the identical environment.
WANs are used to connect LANs and other types of networks simultaneously, so that users and computers at one place can communicate with users and computers at other locations. Many WANs are designed for one specific organization and are personal. Others, built by Internet service providers, supply connections from an organization’s LAN to the Internet. WANs are often built via leased lines. At every end of the leased line, a router connects to the LAN on one side and a hub within the WAN on the other. Leased lines can be incredibly costly. As a substitute of using leased lines, WANs can also be built using less expensive circuit switching or packet switching techniques. Network protocols including TCP/IP send transport and addressing tasks. Protocols together with Packet over SONET/SDH, MPLS, ATM and Frame relay are frequently used by service providers to distribute the links that are used in WANs. X.25 was an significant early on WAN protocol, and is well thought-out to be the “grandfather” of Frame Relay as countless of the basic protocols and functions of X.25 are still in use today (with upgrades) by Frame Relay.
