As it has been mentioned above that networking involves the sharing of information this means file sharing in the organizations is Inch-operated.
This means memorandums; performance failures, presentations and any written Information Including media files that are Important can reach everyone who Is concerned and not having anyone left out. This is done to minimize rescheduling of meetings, missing of deadlines Just because information could not be efficiently shared raising organizational costs.The enabling of file sharing also applies to multiple but authorized personnel, which nameless unethical behaviors In the organization would information end up in the wrong hands. A business organization is known as a social entity where good and services are offered to satisfy customer needs while generating profits to achieve business goals.
Profits can generally be generated by minimizing costs In the business and channeling those finances towards other investments.Computer networking reduces costs incurred in setting up hardware for example a networked printer; there will be no need to set up a lot of expensive printers, storage expenses are also minimized by installing particular software once which can store up humongous amount of data In one location and making it available across all connected computers. Afore mounded It battles with geographical distances, saving on time and allowing decisions to be made quicker. For example a team of experts who are working on a project and at the end have to make a report on It.The rest of the team members do not have to Walt for days neither to see the final draft nor to make amendments, the networking makes It easy to get access it regardless of where they are.
Computer networks also are a source of backup and come in very handy when one system shuts down in the middle of operations there is a certainty of continuity and not putting the business on hold and Interrupting of the flow of the business. For example organizations such as banks. The service might be slow but it does not come to a halt.The collaborations between companies can be implemented which is a powerful source for growth for organizations and how activities are carried out if two or more companies decide to connect their networks.
If one Is a supplier and the other Is a customer delivery of new stock can be communicated easily and thereby making operations easier and the obtaining of new stock in the market faster. Network topologies are ways In which the elements of a network are mapped, physical and logical arrangements of network nodes (www. Technophobe. Com) .
A node as defined by (compartmenting. About. Com/odd/itinformatontechnology/defer_node) as 1 OFF The three topologies that are going to being discussion are the bus topology, ring topology and the star topology. The bus topology consists of all the stations connected to a single cable with terminators at the end of each end. The cable is known as a trunk or back bone cable as shown in the diagram and it connects to every computer or workstation, printer and are all connected in one line.
All the transmissions must pass through each device before reaching final destination.Photo credits: www. Basis. Com/bus_topology_images. Com The terminal acts as a source for absorbing signals when they reach the end of the cable as it travel along the back bone cable. This means the bus topology does not have signal bounce, thus information is retained within the network.
It is a preferable network topology because it has been found to be easy to connect to the different nodes because of its single line characteristic which makes setting up not complicated and easy to repair be there any fault found.As compared to other topologies like the star and the mesh system it requires less cable and is ideal to small networks that plan to stay small. In as much as it maybe ideal because it represents what most organization would want - cutting down costs or incurred of few costs, it also can be a hindrance to flow of businesses. A failure of a device does not necessarily affect the others but the failure information does affect the whole system, thereby shutting it down.
The inability of one device affecting other devices makes error detection hard because network is represented as flawless . Alt also esquires two terminals which need to fixed at each end of network and has a limited size because of the cable length this leads to a great disadvantage as to how many nodes can be connected on one bus. The ring topology is when a host machine is connected to two other computers and not more and the structure is in a circular like form. The flow of information flows in that same way.If information has to travel from one machine to another which is not directly connected to it, it still has to pass through all the other devices before reaching the final destination and in this case a new device can be added to the ring by adding a cable.

Com Although the ring system is not usually used by organizations the upside of it is that there is no central server that is needed since information exchanged between two nodes will still be communicated to the other entire nodes at the same time.Devices can be added because the ring topology can handle load unlike the bus network, at the same time devices can also be removed. The traveling of the data is high speed and it is less costly to set up compared to a star topology. Most organizations do not adapt to it because the failure of a node affects the whole network because one is unconnected to two other nodes which are also connected to a pair.
This means there always have to be system check ups and repairs for all the nodes in the connection.There might not be a limit as to how many nodes are connected but as the number increases the slower the speed of the flow of information because the information still has to pass through all the nodes that are in the network, therefore it can be concluded that a change made either by adding or removing always affects the rest arrangement that all nodes are individually connected to a central point for example switch, and they are connected in a star-like setup the central being in the middle, (Dry.Adhered Shanghai, Computer Networks CASES). The hub is where the signals are transmitted and received. Organizations with the telephone system use this network system. This is the kind of topology I would recommend the organization to use.

This indicates the speed through which information is passed. Errors can be attended to early because they are detected easier because of the isolation of the different devices from each other, and save organization from incurring losses by prolonging repairing process. If the organization is a bank it will also be ideal because a failure of a devices does not affect the others therefore normal business activities can still continue. Businesses operating on a large scale are at an advantage.
