In IP-based virtual computer networks, virtual routing and forwarding works as a transport protocol between multiple instances of a forwarding table. This is an extremely powerful forwarding technology with many benefits. The main benefit is that it allows you to have multiple copies of the same network routed through the same router. You can have different IP addresses for each instance of the virtual networking. You can setup the virtual networking at a local area network (LAN), a wide area network (WAN) or a subnet. In virtual routing and forwarding, one instance of the virtual forwarding software creates in-bound traffic…

What is computer network programming? This is a question many have asked before. Network programming refers to the set of computer programming languages and codes that are used in computer network architecture and its supporting hardware. Network programming can include any or all of the following: IP (Internet protocol), PCMCIA (PCI/IDE over USB), IKE (Internet Key Exchange), PXE ( packet switch eXchange ), SMART (standards for performing authentication and identification), and JOSE (standards for talking to servers). Computer network programming is used extensively in the creation of networks and related computer software packages. Networks in businesses and organizations are vital…

What is network topology? Network topology is a graphical description of the logical and physical configuration of the components of a network. Network topology describes the way in which the nodes and links of a network are physically arranged to correspond to each other. It is an important study in computer network technology. Network topology refers to various types of physical topologies, which include logical arrangement. The logical arrangement describes how various nodes are connected to one another. In the logical arrangement, all the devices are connected to all the other devices and they form a hierarchy. A number of…

What is a Proxy Server? A proxy server acts as an intermediary between your computer or wireless device and the Internet. It makes requests to websites, different servers, and applications on the web for you. Often this is done for free using a free proxy server for WIFI (Wireless Internet Connection).   What is a Virtual Private Network? A VPN is also known as a virtual private network. This is a group of computers or devices that are within the same physical network but have been partitioned. Within a VPN the computers can be networked or set up as if…

In many circles, what is network peering and why is it important? Network peering is when an ISP allows traffic from another company on the same network to move freely through their network without paying a charge for the use of bandwidth. The term "peer-to-peer" is an informal jargon that describes this type of transaction. It is comparable to an Internet phone service where you make calls to another Internet phone line. Peer to peer also refers to a type of computer networking. Why is it important to me? The cost of long-distance telephone calls has reached all-time high levels.…

A network operations center sometimes called a "full service" network Operations Center (NOC), is one or more places from which network management and monitoring, or overall network administration, is performed over a single computer, telecommunications, or satellite network. A Network Operations Center (NOC) houses one or more computers with terminals designed to support network management and monitoring. The primary use of a NOC is to centrally manage a large system of computers. A smaller version of a network operations center is sometimes referred to as an office monitoring center. There are several kinds of NOCs. There are central NOCs that…

What is network tracking? Network monitoring is the process of studying network activity and its characteristics to identify new network vulnerabilities before they are exploited. It can also be used for detecting network abuse and hackers. Most companies now use network monitoring systems for detecting network threats, determining network availability, and fault management. Thus, network monitoring is the backbone of the IT environment. How does network monitoring work? The network monitoring system monitors the traffic that moves through the network. Network traffic consists of communication between network and the host, clients connecting to the host, and other activities like server…

What exactly is network monitoring? Network monitoring is an IT activity that involves watching network elements and endpoints for their functionality, availability, and operation. In addition, it includes notifying network managers if there are problems with their services and monitoring different network layers. There are also times when network monitoring is used for security purposes. For instance, it is used to detect any hacking attempts on networks. Benefits of network monitoring There are several benefits of network monitoring. One is for business owners to keep track of their networks. By having this kind of service, they will be able to…

What is a network interface? Network Interface Card ( NIC ) is a physical device, which is incorporated in a computer, provided by a PCI slot, which connects the computer to external peripherals such as printer, scanner or camera through bus interfaces to the mother board. There are four types of Network Interface controllers: Simplex, LXO, ISA and PCMCIA. They differ in their modes of operation and their configuration and security features. The most widely used type is Simplex. It is found on all new computers and used as their point-to-point adapter. Network interface cards also use standard Ethernet standards…

What is bandwidth capacity? Bandwidth capacity is the total amount of data that can be transferred through your internet service. How much data are you using on your internet service plan today? There is a way to find out this information so you can make a determination on what your current bandwidth capacity is. How to find this number is quite easy. Simply go to the internet service provider's website and check the current bandwidth rates and maximum allowed bits per second. On the measurement results page, there is usually a SIZE column. This will tell you the number of…
