The Importance Of Wireless Router

Thanks to a device such as a wireless router you can create an Internet or computer network without any form of cabling. Most routers in the wireless category have LAN ports and a WAN port for the connection to a wide area network. This port helps the user filter all the routing functions. The wireless router sends signals that are decoded by the other wireless devices connected to the network. This means that the wireless router depends on radio waves for functioning.

It is a lot more convenient to connect devices without cables, not to mention that wireless technology tends to become cheaper too. The local traffic can be directed on the network using the wireless router alone, but for Internet access, a modem is required as well. The modem is usually pre-configured by the cable or DSL (digital subscriber line) Internet service provider. Your network will thus get connected to the world wide web through the wireless router.

One other type of Internet connection is possible if the wireless router also incorporates a modem. The connection of the appliances thus gets simpler when there are not so many devices to connect. The wireless router with built-in modem should support any type of Internet connection, cable or DSL. There may be just one type of Internet access available with some devices, consequently, you should check to make sure that there is a clear match.

The Institute of Electrical and Electronics Engineering (IEEE) regulates the broadcasting standards necessary for the functioning of any wireless router. You’ll find them expressed as the 802.11 standards. There is always a letter such as b, a, g, n and several others that follows this designation, and this letter stands for the protocol. The protocols differ depending on the signal strength and speed, thus, the stronger the signal, the better your network will function. With a quality wireless router, you won’t get performance drops or data errors when you move your laptop away from the router.

The best standards you should look for are 802.11g and 802.11n that operate at very high speeds. Also keep in mind that this protocol of the wireless router needs a match with that of every external portable wifi device or internal wireless card in the network computers.

Wireless Printer with Windows Vista OS

As the topic speaks for itself this article contains information regarding the use of wireless printers in Vista environment. Today we live in that world of mobility. All we need is not just a desk and a desktop to work with in an office cabin. The world has become mobile. Technologies have changed their trend of being wired to wireless. Previously we used wired telephone sets now its the mobile phones world. Postal service was the only way of communication in previous time now its just a few seconds to e-mail someone instead of waiting for days to get your letter delivered. Printers have become wireless these days. Using printers with windows Vista has several advantages.

As we know Windows Vista has changed many things to easily run an OS by a simple user. Vista has a UAC (User Account Control) system that has enabled user to do several tasks that could only be performed by the administrators previously. Installing printers is one of them. Using a wireless printer has many advantages including mobility of use as now you can sit anywhere in your office/home and print your document without actually going to the printer room and doing so. Its economical as now the use of a single hardware is enough to cater the demand of the whole office. No worries about detached cables from the printers. One printer could easily be managed and maintained instead of getting many technicians for several wired printers.
Before Installing A Wireless Printer:
There are several things that one should have in mind before installing a wireless printer. Installing a wireless printer means setting up of a wireless network first that includes a broadband/DSL connection, a wireless router that could establish communication between the users (computers) and the hardware (printers). There should be a LAN network present to use this wireless printer from anywhere in the building. And most importantly a wireless printer that has Wi-Fi enabled in it. So before we install a wireless printer we should be confident that our network is able to support a wireless communication.
How To Install A Wireless Printer?
As we know to install a wireless printer in Vista we need to add a printer first using control panel. Then we need to assign a port. The port should be a TCP/IP port. Then we need to give the IP address to the printer so that all the network computers could communicate to the printer. Then simply install the printer driver. If the driver is not in the recommended list then provide a CD for the driver to install. Now enjoy tour newly installed printer and have fun.

Using Wireless Networks To Increase Office Efficiency

Once you experience the efficiency that wireless networking brings to the office, you will wonder why it took you this long to ride this wave…radio wave that is.

Wireless networking uses radio waves to transmit and receive information from each computers wireless adapter (or NIC ) through an access point, simply called a wireless router, and several computers can share a single wireless router. In effect, wireless networking means office efficiency in the form of:

1. Organization. You will no longer have cables running through the walls, ceilings and floors even though everyone shares the Internet/local area network (LAN) connection and all network peripherals, such as network attached storage (NAS), IP Cam and printer. This creates a neat and organized space in which to work.
2. Flexibility. If you move or change your office arrangement, all you need to do is move the wireless router and the computers with you. No more downtime days to schedule, and no technicians needed because of the easy setup.
3. Scalability. You can add new computers effortlessly and expand the existing wireless network simply adding multiple repeaters.
4. Productivity. Wireless networking offers speed and with speed comes increased output. In fact, the latest 802.11n wireless router offers a speed capability of up to 300 megabits per second (Mbps), and wireless speeds will only continue to improve.
5. Mobility. Regardless of location, you can provide real time access to information for all users in your organization as well as increased services not provided by wired networks, like video conferencing.

All these efficiencies will bring you cost savings in the long run, which can make wireless networking a smart business decision.

Many different ways servers can be utilized to enhance computer performance

As a computer user, you will come across various terminologies the meanings of which you might not know or understand. It is therefore worth your while to have even a brief understanding of these terms so that you will be able to improve your knowledge of computers and their functions. There are various peripheral that can used to enhance the performance of your computer and one of them is the server computer. In order to host a server program on any computer you need one with a high processing speed and additional memory.

This is because the server computer is the one that will be handling the various requests from other computers in its network and as such require special operating systems and extra features to be able to handle all the tasks. Because of this, the price of a server computer is higher than that of a normal computer but is a very useful device to have for use in various programs.

One of them is for the purpose of using one printer that is connected to multiple computers. In order for the printer to share the various print commands issued by the computers in the network, it must have a print server installed. In the present day and age where everything is turning wireless, the better option is to buy a wireless print server that can be connected to an existing network which is then connected to the USB port of the printer. Another advantage of the wireless printer server is that you can use the computer from any location to issue the command for your print job which can save a lot of time as well as money.

You can also eliminate your computer storage problems by getting yourself a NAS server which is the best solution to keeping all your files easily accessible but not crowding your internal or external hard drive. How many times have you wondered whether you should get rid of certain files, music or photos because you thought they were limiting the memory in your computer? By having a NAS server you will be able to get hold of anything you have stored in it and avoid having to make hard copies of all your documents.

The remote access server can help you to get to your files from a remote location. If for instance you dial into a network from a remote location through a modem to a remote access server, you will be allowed access to your files once the authentication process is completed. This will make it possible for you to gain access to whatever you have stored in the computer in the same way as you would when connected to LAN.

When talking about servers, one cannot forget the load balancing server which is found to be very useful for website owners. Especially in the case of popular websites, it’s very difficult for visitors to access them 24/7 because of too much traffic making the servers crash. But having a load balancing server means the other servers are utilized in a balanced way so that one particular server does not get overloaded with incoming traffic. A load balancing server will be helpful in more ways than one to increase the performance of the servers that host such popular websites.

Computer Networking

The basic concept of computer networking is having two or more computers connected together sharing information. The information shared can be files, printers, and programs. The size of a computer network largely depends on the user’s needs. If you are building a home network, then you will likely have one to three computers networked. In a large office, you may have as many as 100 or 200 computers networked together.

Types of Networks
There are different ways to perform computer networking. Wireless networks, or WLAN/WWAN, uses wireless technology to network computers together. This type of computer networking is becoming more popular for the home user. Using a router and a host computer, you can connect multiple computers in your house to the network. If one of those is a laptop, it’s possible to take that computer from room to room as you work. Local area networks, or LAN, are smaller networked areas. Local area networks usually have higher data transfer rates, and do not require special telecommunications services. Wide area networks, or WAN, connects a large group of computers together. These networks are typically designed for one organization’s use. Metropolitan area networks, or MAN, are networks that usually span the size of a city. They use fiber optic cables and are usually wireless. ATMs use metropolitan computer networking.

The OSI model, or Open Systems Interconnection Reference Model, is a type of computer networking that uses layered communication. The seven layers are arranged from bottom to top as: physical, data-link, network, transport, session, presentation, and application. The OSI Model was too complicated to be useful in today’s computer world. Even so, it is still often referenced by IT professionals when they are describing computer networking or network applications.

By setting up a computer network at home, or in your office, you can give multiple users access to files on the host computer. It’s also possible to have users able to share files between their computers. Printers and programs can also be shared among users on a computer network.

This is just a small view into the world of computer networking. Setting up a computer network in your home has never been easier. Today’s technology makes it possible with just a few simple steps.

Telecommunications Processors

Telecommunications processors such as modems, multiplexers, bridges, front-end processors, and other devices perform a variety of support functions between the terminals and computers in a telecommunications network. Let’s take a look at some of these devices and their functions.

Modems. Modems are the most common type of communications processor. They convert the digital signals from a computer or transmission terminal at one end of a communications link into analog frequencies, which can be transmitted over ordinary telephone lines.

A modem at the other end of the communications line converts the transmitted data back into digital form at a receiving terminal. This process is known as modulation and demodulation, and the word modem is a combined abbreviation of those two words.

Modems come in several forms, including small stand-alone units, plug-in circuit boards, and micro electric modem chips. Many modems also support a variety of telecommunications interface functions, such as transmission error control, automatic dialing and answering, and a faxing capability.

Modems are used because ordinary telephone networks were primarily designed to handle continuous analog signals (electromagnetic frequencies), such as those generated by the human, voice over the telephone.

Since data from computers are in digital form (voltage pulses), devices are necessary to convert digital signals into appropriate analog transmission frequencies and vice versa.

However, digital communications networks that transmit only digital signals and do not need analog/digital conversion are becoming commonplace. Since most modems also perform a variety of telecommunications support functions, modems may still be needed in digital networks.

Multiplexers. A multiplexer is a communications processor that allows a single communications channel to carry simultaneous data transmissions from many terminals. Thus, a single communications line can be shared by several terminals.

Typically, a multiplexer merges the transmissions of several terminals at one end of a communications channel, while a similar unit separates the individual transmissions at the receiving end.

This is accomplished in two basic ways. In frequency division multiplexing (FDM), a multiplexer effectively divides a high-speed channel into multiple slow speed channels. In time division multiplexing (TDM), the multiplexer divides the time each terminal can use high-speed line into very short time slots, or time frames.

The most advanced and popular type of multiplexer is the statistical time division multiplexer, most commonly referred to as a statistical multiplexer. Instead of giving all terminals equal time slots, it dynamically allocates time slots only to active terminals according to priorities assigned by a telecommunications manager.

Internetwork Processors. As we have previously mentioned, many local area networks are interconnected by internetwork processors such as bridges, routers, hubs, or gateways to other LANs or wide area networks. A bridge is a communications processor that connects two similar LANs, that is, LANs based on the same network standards or protocols.

A router is a communications processor that connects LANs to networks based on different protocols. A hub is a port switching communications processor. Advanced versions of hubs provide automatic switching among connections called ports for shares access to a network’s resources.

LAN workstations, servers, printers, and other LAN resources are connected to ports, as are bridges and routers provided by the hub to other LANs and WANs. Networks that use different communications architectures are interconnected by using a communications processor called a gateway.

All these devices are essential to providing connectivity and easy access between the multiple LANs within an organization and the wide area networks communications channel. In many cases, star networks take the form of hierarchical networks.

In hierarchical networks, a large headquarters computer at the top of the company’s hierarchy is connected to medium-size computers at the divisional level, which are connected to small computers at the departmental or work group level. A variation of the ring network is the mesh network.

This uses direct communications lines to connect some or all of the computers in the ring to each other. Another variation is the tree network, which joins several bus networks together.

In most cases, distributed processing systems use a combination of star, ring, and bus approaches. Obviously, the star network is more centralized, while ring and bus networks have a more decentralized approach. However, this is not always the case.

For example, the central computer in a star configuration may be acting only as a switch, or message-switching computer, that handles the data communications between autonomous local computers.

Star, ring, and bus networks differ in their performances, reliabilities, and costs. A pure star network is considered less reliable than a ring network, since the other computers in the star are heavily dependent on the central host computer.

If it fails, there is no backup processing and communications capability, and the local computers will be cut off from the corporate headquarters and from each other. Therefore, it is essential that the host computer be highly reliable. Having some type of multiprocessor architecture to provide a fault tolerant capability is a common solution.

Star network variations are common because they can support the chain-of-command and hierarchical structures of most organizations. Ring and bus networks are most common in local area networks. Ring networks are considered more reliable and less costly for the type of communications in such networks. If one computer in the ring goes down, the other computers can continue to process their own work as well as to communicate with each other.

Types Of Telecommunications Networks

ETKjide Area Networks. Telecommunications networks covering a large geographic area are called remote networks, long-distance networks, or, more popularly, wide area networks (WANs).

Networks that cover a large city or metropolitan area (metropolitan area networks) can also be included in this category. Such large networks have become a necessity for carrying out the day-to-day activities of many business and government organizations and their end users.

Thus, WANs are used by manufacturing firms, banks, retailers, distributors, transportation companies, and government agencies to transmit and receive information among their employees, customers, suppliers, and other organizations across cities, regions, countries, or the world.

Local Area Networks. Local area networks (LANs) connect computers and other information processing devices within a limited physical area, such as an office, a building, manufacturing plant, or other work site.

LANs have become commonplace in many organizations for providing telecommunications network capabilities that link end users in offices, departments, and other work groups.

LANs use a variety of telecommunications media, such as ordinary telephone wiring, coaxial cable, or even wireless radio systems to interconnect microcomputer workstations and computer peripherals. To communicate over the network, each PC must have a circuit board installed called a network interface card.

Most LANs use a powerful microcomputer having a large hard disk capacity, called a file server or network server that contains a network operating system program that controls telecommunications and the use of network resources.

LANs allow end users in a work group to communicate electronically; share hardware, software, and data resources; and pool their efforts when working on group projects.

For example, a project team of end users whose microcomputer workstations are interconnected by a LAN can send each other electronic mail messages and share the use of laser printers and hard magnetic disk units, copies of electronic spreadsheets or word processing documents, and project databases.

LANs have thus become a more popular alternative for end user and work group computing than the use of terminals connected to larger computers.

Internetworks. Most local area networks are eventually connected to other LANs or wide area networks. That’s because end users need to communicate with the workstations of colleagues on other LAN’s, or to access the computing resources and databases at other company locations or at other organizations.

This frequently takes the form of client-server networks, where end user microcomputer workstations (clients are connected to LAN servers and interconnected to other LANs and their servers, or to WANs and their mainframe super servers).

Local area networks rely on internetwork processors, such as bridges, routers, hubs, or gateways, to make internetworking connections to other LANs and wide area networks.

The goal of such internetwork architectures is to create a seamless “network of networks” within each organization and between organizations that have business relationships.

such networks are designed to be open systems, whose connectivity provides easy access and interoperability among its interconnected workstations, computers, computer-based devices databases, and other networks.

The Internet. The Internet is the largest “network of networks” today. The Internet (the Net) is a rapidly growing global web of thousands of business, educational, and research networks connecting millions of computers and their users in over 100 countries to each other.

The Internet evolved from a research and development network (ARPANET) established in 1969 by the U. S. Defense Department to enable corporate, academic, and government researchers to communicate with E-mail and share data and computing resources.

The Net doesn’t have a central computer system or telecommunications center. Instead each message sent has an address code so any computer in the network can forward it to its destination.

The Internet doesn’t have a headquarters or governing body. The Internet society in Reston, Virginia, is a volunteer group of individual and corporate members who promote use of the Internet and the development of new communications standards or protocols.

These common standards are the key to the free flow of messages among the widely different computers and networks in the system.

The most popular Internet application is E-mail. Internet E-mail is fast, faster than many public networks. Messages usually arrive in seconds or a few minutes, anywhere in the world. And Internet E-mail messages can take the form of data, text, fax, and video files.

The Internet also supports bulletin board systems formed by thousands of special interest groups. Anyone can post messages on thousands of topics for interested users to read. Other popular applications include accessing files and databases from libraries and thousands of organizations, logging on to other computers in the network, and holding real-time conversations with other Internet users.
