Computer Networking Solutions For Small Businesses

Many terms of the computer networking fundamentals for small businesses have come from the physical world of transportation. Some examples of such terms are ports, hubs, bridge, switching and routing. However, this simile is not unjustified because networks have same importance regarding the boom of the information era, as the transportation to the industrial era. Both computer networks and transportation system require very sound infrastructure.

Computer Networking is connecting the Computers: Most fundamental form of computer networking goes back to connecting any two electronic equipments for the transfer of data between them. Third equipment only helps the communication of data. However, connecting a printer to computer simply with the help of a USB cable is not called a network. It will be a part of the network if connected with router or switch. Advent of Internet has forced the most of the companies to think about the computer networking. No matter how small business you are running, you need to have computer-networking facilities for publicity, email and online marketing of your products and services. If you do not have a well-established network of computer, your competitors will leave you behind in contacting the prospective customers.

The Biggest Advantage is File Sharing: File sharing is perhaps the most talked about component of the computer networking fundamentals. File sharing is simply centralized grouping and organization of data files on a network server. Availability of all the data files at one place makes managing documents and data easier. Furthermore, you can also avoid the inconvenience caused by the inconsistant scheme of work among the different departments of the business. The newer versions of the network operating systems give tremendous control to the administrator. He is in complete control whether a person can get access to a particular file or not.

Sharing of Printers Saves Both Time and Money: Second important component of the computer networking fundamentals for small businesses is printer sharing. It saves a lot of money and time that you would have spent on the purchasing and maintenance of printers. The printers connected to the computer network have more features than those connected to single computers.

Email: One should also learn the importance of email to get the full understanding of computer networking fundamentals for small businesses. Group email facilitates fast and effective communication among the employees. Small business can also improve their scheduling, task assignment and contact management with the help of group or internal email. Moreover, in-house communication of documents is better than faxing because group emails are less expensive easier and unbelievably fast.

Computer Networking - How It Works

Computer networking is a process of sharing data and shared resources between two or more connected computers. The shared resources can include printer, Fax modem, Hard disk, CD - DVD Rom, Database and the data files. A computer network can be divided into a small or local area network, a networking between computers in a building of a office (LAN), medium sized network (MAN), a network between two offices in a city and Wide network (WAN) a network between the computers, one is locally and the other can be thousands of miles away in any other country of the world.
WAN connectivity is achieved by a network device known as “Router”. The internet is the world’s largest WAN network, where millions of computers from all over the globe and connected with each other.
Networking is the practice of linking two or more computers or devices with each other. The connectivity can be wired or wireless. A computer network can be categorized in different ways, depends on the geographical area as mentioned above.
There are two main types of the computer network client-server and peer to peer. In the client server computing, a computer plays a major role known as server, where the files, data in the form of web pages, docs or spread sheet files, video, database & resources are placed.
All the other computers in the client/server network are called clients and they get the data from the server. In the peer to peer network all the computers play the same role and no computer act as a centralized server. In the major businesses around the world client-server network model is in major use.
A network topology defines the structure, design or layout of a network. There are different topologies like bus, ring, star, mesh, hybrid etc. The star topology is most commonly used network topology. In the star topology, all the computers in the network are connected with a centralized device such as hub or switch. Thus forms a star like structure. If the hubs/switch fails to work for any reason then all the connectivity and communication between the computers of a network will be halted.
In the network, a common communication language is used by the computers and the network devices and this language is known as protocols. The most commonly used and popular protocols on the internet and in the home and other networks is called TCP/IP. TCP/IP is not a singleprotocol but it is a suite of several protocols.
A network can be a wired or wireless and TCP/IP protocol can work both in types of network.
A data flow in a computer network can be divided into seven logical layers called OSI layersmodel that was developed by Intel and Xerox Corporation and was standardized by ISO.
1. Application layer
2. Presentation layer
3. Session layer
4. Transport layer
5. Network layer
6. Data Link layer
a. Media access control sub-layer
b. Logical link control sub-layer
7. Physical layer.
A network can be divided into different scales and ranges and it depends on the requirement of the network and the geographical location. Computer Network can be divided into Local Area Network, Personal Area Network, Campus Area Network, Wireless Local Area Network,Metropolitan Area Network and Wide Area Network.
There are several network connection methods like HomePNA, Power line communication, Ethernet and Wifi connection method.A network can also be categorized into several different types based on the services it provides like Server farms, Storage area networks, Value control networks, Value-Added networks,SOHO network, Wireless network and Jungle networks.

Networking With A Router

Using a router on broadband and/or wireless home networks
A network router is a small electronic device that allows you build a home network simply. The home router serves as the core or "centerpiece" of the network to which computers, printers and other devices can be connected. Networking with a router helps you to (for example):

share files between computers
share an Internet connection between computers
share a printer
connect your game console or other home entertainment equipment to the Internet
Routers are not necessarily required to build a network. For example, you can connect two computers directly to each other with just a cable (or without wires in some cases). Home routers offer convenience and easier maintenance as your network grows.

Choosing a Network Router
You can choose from among several different types of home network router products.

The two most common types in popular usage are the 802.11b and 802.11g WiFi models. 802.11g is the newer technology, but 802.11b routers often can do the job for an even lower cost.

Installing a Network Router

Network routers receive their power from an ordinary home electrical socket. When powered on, lights (LEDs) signify the unit is operating.

Network routers must be carefully configured when they are first installed. Like computers and other devices on the home network, routers must be set up with IP addresses. Routers also offer optional (but strongly recommended) security features.

Routers contain built-in software to enable setup. You access this software through your Web browser on any computer connected to the router.
