If users connect to the system by rote via dial-up line(e.g. from home), access should be restricted by a dial-up access control. Dial-up access controls prevent unauthorized acces from remote users that attempt to access a secured environment. These controls range from dialback controls to remove user authentication. Dial-back controls are used over dial-up telecommunication lines.

Internet Goes Rural?

Satellite internet can be a convenient way to access the World Wide Web from a remote location. Cable internet, DSL and other wired internet services are usually limited to more densely populated areas. Chances are that if a satellite television service works in an area then a satellite internet provider can be found to provide service in the area. There must be a direct line to the southern sky in order for the satellite to get a signal. This allows those in more rural areas to access the internet at faster speeds than traditional internet services that are available. In some cases, even a cell phone will not work in a remote area even though satellite internet and television services will. Like satellite television services, satellite internet reception is dependent on the weather. Heavy snow and rain can impede the signal, as can trees and branches. Most internet providers will offer several different plans to choose from depending on usage requirements and budget. The plans are tailored to the heavy users as well as the lighter internet users. Like most internet services, satellite internet providers have limitations on the amount of bandwidth that can be used in a certain timeframe. This limitation is dependent upon the plan that is chosen. If for some reason the limit is exceeded then the satellite internet provider will put a cap on your speed until it resets. This is called the fair access policy. This policy sets a cap on those who use huge amounts of bandwidth. Some satellite internet providers will provide a free download period for those that need it. This time is usually at off peak time periods as to not interfere with other users service. Satellite internet provides much faster download speed than traditional dialup services. Photos, music and videos can be downloaded in a fraction of the time that dialup allows. Finding a satellite internet provider may be necessary for a user that uploads or downloads a large amount of photos or videos.


What is the difference between the lan wan man?

Local area networkA local area network (LAN) is a network that connects computers and devices in a limited geographical area such as home, school, computer laboratory, office building, or closely positioned group of buildings. Each computer or device on the network is a node. Current wired LANs are most likely to be based on Ethernet technology, although new standards like ITU-T G.hn also provide a way to create a wired LAN using existing home wires (coaxial cables, phone lines and power lines).[2] Typical library network, in a branching tree topology and controlled access to resourcesAll interconnected devices must understand the network layer (layer 3), because they are handling multiple subnets (the different colors). Those inside the library, which have only 10/100 Mbit/s Ethernet connections to the user device and a Gigabit Ethernet connection to the central router, could be called "layer 3 switches" because they only have Ethernet interfaces and must understand IP. It would be more correct to call them access routers, where the router at the top is a distribution router that connects to the Internet and academic networks' customer access routers.The defining characteristics of LANs, in contrast to WANs (Wide Area Networks), include their higher data transfer rates, smaller geographic range, and no need for leased telecommunication lines. Current Ethernet or other IEEE 802.3 LAN technologies operate at speeds up to 10 Gbit/s. This is the data transfer rate. IEEE has projects investigating the standardization of 40 and 100 Gbit/s.[3]Personal area networkA personal area network (PAN) is a computer network used for communication among computer and different information technological devices close to one person. Some examples of devices that are used in a PAN are personal computers, printers, fax machines, telephones, PDAs, scanners, and even video game consoles. A PAN may include wired and wireless devices. The reach of a PAN typically extends to 10 meters.[4] A wired PAN is usually constructed with USB and Firewire connections while technologies such as Bluetooth and infrared communication typically form a wireless PAN.Home area networkA home area network (HAN) is a residential LAN which is used for communication between digital devices typically deployed in the home, usually a small number of personal computers and accessories, such as printers and mobile computing devices. An important function is the sharing of Internet access, often a broadband service through a CATV or Digital Subscriber Line (DSL) provider. It can also be referred as an office area network (OAN).Wide area networkA wide area network (WAN) is a computer network that covers a large geographic area such as a city, country, or spans even intercontinental distances, using a communications channel that combines many types of media such as telephone lines, cables, and air waves. A WAN often uses transmission facilities provided by common carriers, such as telephone companies. WAN technologies generally function at the lower three layers of the OSI reference model: the physical layer, the data link layer, and the network layer. Campus networkA campus network is a computer network made up of an interconnection of local area networks (LAN's) within a limited geographical area. The networking equipments (switches, routers) and transmission media (optical fiber, copper plant, Cat5 cabling etc.) are almost entirely owned (by the campus tenant / owner: an enterprise, university, government etc.).In the case of a university campus-based campus network, the network is likely to link a variety of campus buildings including; academic departments, the university library and student residence halls.Metropolitan area networkA Metropolitan area network is a large computer network that usually spans a city or a large campus. Sample EPN made of Frame relay WAN connections and dialup remote access.Sample VPN used to interconnect 3 offices and remote usersEnterprise private networkAn enterprise private network is a network build by an enterprise to interconnect various company sites, e.g., production sites, head offices, remote offices, shops, in order to share computer resources.Virtual private networkA virtual private network (VPN) is a computer network in which some of the links between nodes are carried by open connections or virtual circuits in some larger network (e.g., the Internet) instead of by physical wires. The data link layer protocols of the virtual network are said to be tunneled through the larger network when this is the case. One common application is secure communications through the public Internet, but a VPN need not have explicit security features, such as authentication or content encryption. VPNs, for example, can be used to separate the traffic of different user communities over an underlying network with strong security features.VPN may have best-effort performance, or may have a defined service level agreement (SLA) between the VPN customer and the VPN service provider. Generally, a VPN has a topology more complex than point-to-point.
