Parallel ports usually used for connecting printers, computers, and other devices that required high bandwidth. The port is also used for interconnection between interior components of the devices. Parallel ports can be transmitted simultaneously over multiple wires. Theoretically parallel port is eight-time faster than a serial port. The serial port sends one bit while at […]
A serial port allows a PC or network devices to transmit or receive data one bit at a time. A serial interface is the oldest types of an interface that was also used to connect printers and external modems to a PC at that time. Modern serial ports are used in scientific instruments such as […]
VPN is the abbreviation of a virtual private network. A VPN technology creates a safe and encrypted connection over an unsecured network, such as the internet. It extends a private network using a public network such as the internet. A virtual private network is using virtual connection known as VPN tunnels instead of using a […]
Cellular networks are the type of wireless WAN technologies. Cellular networks provide service to connect users and remote locations where no other WAN access technologies available. Millions of users use there Smartphone and tablets to email, surf the web, download apps, and watch videos. We can easily connect the computers, laptop including routers with the […]
Wireless internet uses wireless connectivity via radio waves instead of wires on a personnel computer, laptop, smartphone etc. Initial wireless technologies lack the high speed of broadband internet connection e.g cable and DSL, but the latest wireless technologies cover the gap. Wireless Internet service providers (WISP) typically provide wireless internet services to home users and organizations. The […]
Network and Internet Access through Cable TV is a type of broadband internet access that uses the resources of the television cable system. It provides network edge connectivity from the internet service provider (ISP) to an end-user of the internet services in the same way as DSL and fiber to the home (FTTH) provides. Cable […]
VSAT is the abbreviation of Very small aperture terminal. It is important WAN technology for both home user and organization; they needed connectivity in remote areas where there is no possibility of fiber optic, copper cable and microwave. It is the solution that creates a private WAN using satellite communications. A VSAT contains is a […]
MPLS is the abbreviations of Multiprotocol Label Switching. It is a WAN protocol that sends data from one router to another router, based on short path labels rather than IP network addresses. It was created in 1994 to 1999 as an alternative to Internet Protocol (IP) routing. It was the more effective alternative to multilayer switching […]
Ethernet was initially considered not suitable as a WAN access technology because of the maximum cable length supported was only up to a kilometre. However, newer Ethernet standards with fiber optic have made Ethernet an important WAN option. For example, the IEEE 1000BASE-ZX standard supports up to 70 km of distance. Ethernet WAN provides high-bandwidth […]
ATM is the abbreviation of Asynchronous Transfer Mode. It is using time-division multiplexing (TDM) for data communications. It is capable of transferring voice, video, and data through private and public networks. ATM is working on a cell-based architecture in place of frame-based architecture. The size of the Asynchronous Transfer Mode cell is fixed to 53 […]
