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.

How To Design Network Server

Network server is a most important component of a computer network because the entire computer network is administered, controlled and managed through it. Before designing a network server for your organization, you should have the adequate knowledge about the following things.

Server Processor

Processor is a heart of the CPU. It processes all the commands, instructions and commands and execute them to perform certain actions. Pentium processors are very reliable in performance and speed and trend is growing to use the multiprocessor servers to share the load on each processor. If one processor fails to work due to any reason, there is no effect on the other processor in the same server so it’s a wise decision of the network administrators to use the multiprocessor server for company’s network.

Hard Disk

Hard disks are used to store all the data in permanently. Hard disk is a mechanical device and while selecting the hard disk you should consider the S.M.A.R.T (Smart Monitoring and Reporting Technology). This technology monitors the hard drives and predicts the any failure in the hard drivers. Today, most of the server providers provide hot swap disk drives, this means that if one there is any error occurred in the hard drives, it can be replaced with the other hard drives while the server is in the working mode.

Clustering

In a clustering environment, two or more servers operate as a single server and the failure of the one server does not affect on the other servers. Clustered environment has the benefits such as high performance, reliability and load balancing.

Memory Performance

While selecting the physical memory for the server it should be considered the memory support Error Correcting Code technology. ECC technology fixes and repairs any single bit errors and report the multi bit errors. High memory is very vital for the server for its best performance, speed and continuous work.

Power Supply

Most of the computers come with the multi power supplies. This means in case of failure of the one power supply, does not affect on the other power supply in the same computer and in this way computer works normally. Multi power supplies are hot swappable like the hard disks i.e. faulty power supplies can be replaced with the new ones while the server is in the working mode.

UPS

UPS or uninterrupted power supply are very important in a network environment because a sudden jerk of the electricity may cause of the hard drives or mother boards of the server as well as the other computers in the network. A UPS normally provide a backup of 3-4 hours and during that time server and other computers can be setup and the files or other data can be saved.

Cooling Fans

The cooling system inside the server is provided by the cooling fans. Cooling fans pull the cool air inside the server and through out the heat from the server. The failure of the cooling fan results in the automatic shutdown of the server due to the high buildup of the heat. Many vendors of the computer systems are providing the hot swappable cooling fans.

Computer Monitoring Hardware

There is a specially designed adapter to monitor the performance of the different parts of the hardware of the computer. This adapter can also be controlled by a modem remotely.

Computer Monitoring Software

Different computer monitoring software is available in the market and their main purpose is to monitor the performance of the server and the client computers.

Data Server Location

Network server should be placed in a dust free, cooling capable and clean environment and only the authorized users should be allowed to enter in the server room.

Hopefully my above mentioned tips will help you building a better server for your computer network

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.
