Virtual Private Network (VPN)
Virtual Private Network (VPN) A VPN or a Virtual Private Network is a dedicated communications channel which is streamlined using another network. A VPN is useful for companies which need their own space on the internet. For example a business community that needs to secure its own network on the internet and wants to carry out various business activities within this environment can use a VPN. The VPN operates on a different and more complicated topology than a point to point network. Also VPN dos not stress on security features and rather the network on which it is based may…Print Servers
Print Servers Print server is a server or advice that is used to connect many printers of a network to it. Using the print server any computer on the network can give a print command to the server and the print server will get the job done accordingly. Usually a print server is configured on a computer that is running windows operating system. The main use of print server is in large offices where many people are giving print commands from their computers simultaneously. A printer by itself that is connected to the network without the print server cannot process…Web Server
Web Server A web server can be a program or the computer itself which receives the requests from various other browsers and responds to those requests. These requests are all HTTP requests that are being sent for some HTTP documents. There are two kinds of web servers available. The web server program and the web server computer are two different devices. A web server computer accepts larger amount of requests and is usually used to receive many requests at a time. It is a public computer present on the internet. The web server program is software program that runs on…Home Networking
Home Networking Home networks are creating the modern day offices at home for individuals who prefer to stay at home while working. For domestic usage the home networks found no uses as most people could afford only one computer. However there are families that find one computer is not enough for them to do everything. People read emails; many women set up home based business, their children might want the computer for school work. With the increase in usage of computer by all the members of a family, the need for more than one computer is evident. When there is…Network Topology
Network Topology There are two levels in a network topology and there are five kinds of network topologies. The networks can be connected at two levels, the physical and the other is logical. A topology basically defines how the network has to be designed and provides a structure to the network. The five different kinds of topologies are • Bus • Ring • Star • Tree • Mesh Bus Topology The bus topology is a series of nodes which are all connected to a backbone. Bus networks typically work well for smaller networks and use Ethernet cables for networking. It…Network Management
Network Management Network management is the method of managing the tools that belong to a network and maintaining, administering all the systems that are connected in the network. For one to be able to efficiently manage a network that person should be a qualified network administrator and should have in depth knowledge of the functionalities of the network and different topologies of network. There are two aspects in any network, one is the logical aspect and the other is the physical level. The network administrator should be good at both the logical and the physical aspects to be able…Network Designs
Network Designs While designing a network many factors have to be taken into consideration like the area to be covered, capacity of data that has to be handled and even security issues. However when it comes to networks there are LANS or the Local Area Networks and WAN the Wide Area Networks. These are the two major types of networks which are further subdivided into topologies. Any of the topology has to be based on one of the two kinds of network. Topologies A topology means the layout of the network and in what way the nodes or the computers…Bus Topology
Bus Topology From the name of the network itself many inferences of the network can be derived. A bus topology in more technical terms means that it is a method of transmission on networks that uses a common vehicle for transmissions and thus it is categorized as shared communication. Imagine a bus picking up various people from one stop and dropping of people as it travels and then picking a few more. That is what happens in a bus network exactly. However in a Bus topology only one device is allowed to transmit at a given point of time. The…Asynchronous Transfer Mode (ATM) Switching
Asynchronous Transfer Mode (ATM) Switching The Asynchronous Transfer mode or more popularly known as ATM is actually a part of the International Telecom Standards. Using the ATM protocols information can be sent and received in small secure cells. However for ATM connections to work there should be a constant connection. The ATM technology has found a large usage in cell switching and technologies that use multi-plexing. Also the benefits of using ATM technologies are that you can have a fixed bandwidth from 1 MBPS to Gigabytes. ATM Devices Functionality There are two components in an ATM device, one is the…Bluetooth Technology Models and Future
This article discusses about various Bluetooth Technology Models & Application in the market and Bluetooth in Future. Bluetooth Technology Models & Applications HomeRF like Bluetooth is a specification for connectivity and mobility in a home-like environment. HomeRF Working Group has developed a specification for wireless communications in the home called the Shared Wireless Access Protocol (SWAP). The Federal Aviation Administration (FAA) and other aviation regulatory bodies worldwide are currently reviewing the use of Bluetooth products on private and commercial aircraft. In the U.S. the FAA is the governing body to grant approval for Bluetooth product use on aircraft; therefore, we…Bluetooth Vs 802.11b Wireless LANs
This article discusses about the differences between Bluetooth and 802.11b Wireless LANs, Co-existence of Bluetooth & Wi-Fi and Advantages & Disadvantages. 1) Bluetooth has lower distance range (less than 30 feet) than 802.11b (up to 200 feet). Therefore, you would need many more access points to cover the same area of an office. Simple mathematics will show that you may need as many as 20-50 times the number of access points 2) Bluetooth has generally lower speed than that of 802.11b wireless LANs. 3) Bluetooth components (chips and radios) and device adapters are cheaper than wireless LAN components and adapters. 4)…How Bluetooth Technology works?
This is the first article on the Bluetooth Technology by Nupur Mittal. Bluetooth is a high-speed, low-power microwave wireless link technology, designed to connect phones, laptops, PDAs and other portable equipment together with little or no work by the user. Connective convenience Unlike infra-red, Bluetooth does not require line-of-sight positioning of connected units. The technology uses modifications of existing wireless LAN techniques but is most notable for its small size and low cost. The current prototype circuits are contained on a circuit board 0.9cm square, with a much smaller single chip version in development. The cost of the device is…What is Bluetooth Technology
This is the first article on the Bluetooth Technology by Nupur Mittal. Blue tooth has been regarded as a new wave in the IT sector from the day of its origin. Blue tooth is continuing its success story. Toshiba introduced blue tooth in September 2000 to consumers for $ 199. The new technology is supported by SIG (Special Interest Group). SIG founded in 1998 consists of 2000 members who have access to the Blue tooth specifications (information needed to make a blue tooth product). The SIG works to promote the Blue tooth technology and consists of members like IBM, Intel,…
