Computer Networking is simply a group of computers that are connected to each other in some way for the purpose of communicating to each other. Computer Networking has existed for about 50 years, with the first computer network developed in the 1960s
A computer network, or data network, is a digital telecommunications network which allows nodes to share resources. In computer networks, computing devices exchange data with each other using connections (data links) between nodes. These data links are established over cable media such as wires or optic cables, or wireless media such as Wi-Fi.
Why companies use network?
A computer network, or data network, is a digital networkers networks, computing devices exchange data with each other using connections (data links) between nodes. These data links are established over cable media such as wires or optic cables, or wireless media such as Wi-Fi. Now these days the use of network is more. People use network for his resources. Some people use network for communication and entertainment. Use of network people connects with world. The more use of network is Local area network (LAN) connects your company’s computer for share and exchange a variety of information.
Advantage of network:
If you need to store a file on another computer. A network makes it easy for everyone to access the file and prevents people from creating different version.
You should know that it’s vital to back up your computer data regularly. A network makes it easier to back up all of your companies data on off side server, a set tape, CDs, or other backup systems (of course another aspect of data protection is data security.
Companies are used network for sharing information. Information sharing is the main function of the company. People use to transfer there file from one company to other.
Communication and collaboration:
Communication is also important part of network. Peoples use communication for communicate with other companies or peoples. In company people use network to communicate with other companies for his resources or profit. In a larger office, you can use e-mail and instant messaging tools to communicate quickly and to store messages for future reference.
If you use a computer, chances are you also use a printer. With a network, several computers can share the same printer. Although you might need a more expensive printer to handle the added workload, it’s still cheaper to use a network printer than to connect a separate printer to every computer in your office.
A variety of scheduling software is available that makes it possible to arrange meetings without constantly checking everyone’s schedules. This software usually includes other helpful features, such as shared address books and to-do lists.
Having your own network allows greater mobility while maintaining the same level of productivity. With remote access in place, users are able to access the same files, data, and messages even when they’re not in the office. This access can even be given to mobile handheld devices.
You should know by now that it’s vital to back up your computer data regularly. A network makes it easier to back up all of your company’s data on an offsite server, a set of tapes, CDs, or other backup systems
With a motivated group of business owners comes an abundance of opportunities! There are always lots of opportunities that come from networking and in fact this is where the benefits of business networking are huge.
Raising your profile:
Being visible and getting noticed is a big benefit of networking. Make sure you regularly attend business and social events that will help to get your face known. You can then help to build your reputation as a knowledgeable, reliable and supportive person by offering useful information or tips to people who need it. You are also more likely to get more leads and referrals as you will be the one that pops into their head when they need what you offer.
By regularly networking, and pushing yourself to talk to people you don’t know, you will get increased confidence the more you do this. This is really important as a business owner, because your business growth is very dependent on talking to people and making connections.
Disadvantage of network
Not all networking leads to successful business relationships. For every networked contact that develops into a mutually beneficial transaction, there are many others that lead nowhere. Because of this, the resources that are used in networking, including management and employee hours, computer equipment and telephone bills, need to be taken into account in their totality when determining the net value of networking.
Competition for Employees:
While most businesses can benefit from close relationships with other businesses, these interactions are not always purely beneficial. If you employ individuals who are less than satisfied with your working conditions, remuneration or other elements of your workplace, they may be lured away by your competition. The more networking that is engaged in by business owners and their employees, the more opportunity there is for this type of inter-corporate employee piracy.
In the world of business, time is indeed money. The cultivation of network contacts within your own company and throughout the business world requires a great deal of time, particularly when it involves personal relationships, socializing and the development of interpersonal trust. Unlike the world outside of business, all of these things need to be weighed against their profitability and usefulness for the success of the company. In many cases, networking is transformed into mere socializing and ends up doing little to promote either the business objectives of management or the job security of employees.
Social Networking and Employees:
Social networking sites have become a dominant force on the Internet. For managers of workplaces in which employees have access to the Internet, this can become a potential problem. Particularly in cases where employees are unmotivated and lack a commitment to the work they are doing for the company, personal networking objectives may take precedence over work responsibilities. Unfortunately, there is no simple solution to this problem since the Internet has become so central to business activities, and a company would be crippled if it denied its employees online access.
Considering the large number of people using a computer network and sharing files and resources, your security would normally be at risk. As you can see, there are illegal activities on a network, especially on the web, which you need to be aware and careful of.
Dependent on computers:
Since this technology’s process mostly involves the use of computers, people have been relying on these machines rather than exerting some physical effort, which can be bad health wise.
Computer networking involves a process that is operated using computers, so people will be relying more of computer work, instead of exerting an effort for their tasks at hand. Aside from this, they will be dependent on the main file server, which means that, if it breaks down, the system would become useless, making users idle.
Computer viruses and malware:
There would be instances that stored files are corrupt due to computer viruses. Thus, network administrators should conduct regular check-ups on the system, and the stored files at the same time.
For a computer network to work efficiently and optimally, it requires high technical skills and know-how of its operations and administration. A person just having basic skills cannot do this job. Take note that the responsibility to handle such a system is high, as allotting permissions and passwords can be daunting. Similarly, network configuration and connection is very tedious and cannot be done by an average technician who does not have advanced knowledge.
Though computer networks are said to be an inexpensive system when it is already running, its initial set up cost can still be high depending on the number of computers to be connected. Expensive devices, such as routers, switches, hubs, etc., can add up to the cost. Aside from these, it would also need network interface cards (NICs) for workstations in case they are not built in.
Edges of networking:
Edge device is a device which provides an entry point into enterprise or service provider core networks. Examples include routers, routing switches, integrated access devices(IADs), multiplexers, and a variety of metropolitan area network (MAN) and wide area network (WAN) access devices. Edge devices also provide connections into carrier and service provider networks. A network located on the periphery of a centralized network. The edge network feeds the central, or core, network.
The network provided by a content delivery service provider that duplicates Internet content on many servers around the world. See CDSP.
Points of networking:
Switches are the foundation of most business networks. A switch acts as a controller, connecting computers, printers, and servers to a network in a building or a campus.Switches allow devices on your network to communicate with each other, as well as with other networks, creating a network of shared resources.
There are two basic types of switches to choose from as part of your networking basics: managed and unmanaged.
• An unmanaged switch works out of the box but can’t be configured. Home-networking equipment typically offers unmanaged switches.
• A managed switch can be configured. You can monitor and adjust a managed switch locally or remotely, giving you greater control over network traffic and access.
Routers connect multiple networks together. They also connect computers on those networks to the Internet. Routers enable all networked computers to share a single Internet connection, which saves money. A router acts a dispatcher. It analyzes data being sent across a network, chooses the best route for data to travel, and sends it on its way.
An access point* allows devices to connect to the wireless network without cables. A wireless network makes it easy to bring new devices online and provides flexible support to mobile workers.
An access point acts like an amplifier for your network. While a router provides the bandwidth, an access point extends that bandwidth so that the network can support many devices, and those devices can access the network from farther away.
