Be it a project, a small business, a large enterprise or a corporate, no single person is capable enough to handle everything in the best way possible. The success of a company or a project is basically the success of the team behind it, who all work together towards the same goal. So, is the case with computers. When more than one computers combine or are connected to share created resources, processes, etc., they form a computer network. These connected computers are then liable to share software modules like ‘team viewer’ for file sharing, hardware resources like printer sharing, as well as easy document-sharing (input or output) on the whole. The major advantages derived by an enterprise through these networks are:
SHARING OF RESOURCES: First and foremost advantage of networks is that it allows resource sharing, hardware as well as software. Thus, work does not gets stopped at any time due to unavailability of a particular resource. It thus, also helps in saving precious time.
COST-EFFECTIVENESS: Since, one resource is shared by many workstations on a network, it proves to be very cost-effective overall for an enterprise as they are required to invest only in a minimum number of software and hardware only.
OPTION OF TOOLS AVAILABLE: A network enables sharing of resources. Thus, if a particular employee requires a particular tool not installed on his computer, he may access it through the network.
MAKE OF THE WORKSTATION: Companies like Microsoft, Hp, Asus, etc. develop different kinds of machines. A network provides employees to choose a device from the network that shall be most suited to their job type.
SENSITIVE INFORMATION: All companies consist of their own records, their own set of employee-tasks and projects in progress, which is generally confidential. If this information is stored in personal computers of employees, they may take them as well when they leave. Thus, networking enables storage of data on company-owned centralized servers.
INSTANT ACCESS TO ALL INFORMATION: A company may create its own personal ease intranet. It shall enable easy access of company information by employees worldwide with of access through the intranet network.
Thus, a company incorporating any software or hardware for their employees should ensure that they enable network integration for their optimum usage.
There exist basically 3 types of Networks, wherein the computers and separate hardware’s attached to the network are called ‘nodes’:
• Peer-to-Peer Network: In this kind of network, personal computers are mutually connected to share resources. They thus, do their own processing and prodce their own set of output.
• Client-Server: This kind of network is the most effective in Intel-based computers wherein, a central server, like the mainframe does all the processing and light client interface workstations only provide the output.
• Thin Client-server network: This network type is the most used in businesses and is a cross between the other two types of network. Here the main processing is done by the central server, but small computing and interface development is undertaken by the client-end.
Networks in a company may be cabled (by a physical Ethernet wire) or may be wireless (managed by radio waves transmission) in nature. As per the manner in which the various computers are connected clearly describes the network topology:
• Star Topology- in this type of network there is one central node or computer. It extends separate cables to all other nodes.
Pros:- Fault in one cable connection does not affect the other sites of the network.
Cons:- This wire system involves a lot of cabling
• Bus Topology:- In this network, like a series connection of electricity one cable connect all. Every information goes to the last node.
Pros:- The system involves minimalistic cabling.
Cons:- If the cable breaks at a point in the system the whole system comes down.
• Ring Topology :- In this system one cable connects all the nodes in series but every node is also connected to one another
Pros:- The information is passed on to several nodes until the destination is reached
Cons:- A broken node may may create issues for some information or command sharing.
• Mesh Topology :- This complex network system is the most used one in the companies today, here each node is physically connected to every other node parts of the system may have thin or thick meshed topology as per requirements. Complex meshed topologies are generally the backbone of telecommunication companies.
Pros:- Fault tolerant and not prone to bottle necks
Cons:- Usually a complex network
• Wireless Topology:- In these times of internet where all connectivity is being done through radio waves businesses and their network have also gone wireless they generally inculcate specific radio frequencies to transmit data under their various area network. The various kinds of these networks that span different areas include:
LAN: Local Area Network, generally spans a small area like an office building. It requires login in the network by a dedicated username and password. These networks are managed by an individual or a department. They are nowadays mostly dependent on wi-fi transfer technology.
WAN: Wide Area Networks span greater physical areas. ‘Internet’ in itself is the world’s largest WAN. It allows access of information globally without cables.
Metropolitan Area Networks, Campus area Networks, System Area Networks are all examples of kinds of WAN’s.
Different kinds of organizations require different kinds of networks and different networks require different kinds of computer systems. For example: a freelancer setup may require personal computers only, but with an access to a company WAN. Similarly a small company may make-do with a client server computer system organization with a cabled mesh technology of the network. Whereas, huge corporate may require thin-client servers with huge intranet’s. You just need to ensure the network-enabling depth of each of your resource.
