environment in great detail. Thus‚ a sensor network can be described as a collection of sensor nodes which co-ordinate to perform some specific action. Unlike traditional networks‚ sensor networks depend on dense deployment and co-ordination to carry out their tasks. Previously‚ sensor networks consisted of small number of sensor nodes that were wired to a central processing station. However‚ nowadays‚ the focus is more on wireless‚ distributed‚ sensing nodes. But‚ why distributed‚ wireless sensing? When

Ethernet Hubs An Ethernet hub is also called a multiport repeater. A repeater is a device that amplifies a signal as it passes through it‚ to counteract the effects of attenuation.

Network attached storage is a computer data storage connected to a computer network providing access to a group of clients. This allows you to share files among multiple computers. Some of the benefits to this is that is has faster data access‚ easier administration‚ and a simpler configuration. NAS contains one or more hard drives often arranged in redundant storage containers or RAID. A typical speed of the network adapter is 1 GB depending on the NAS and if you are building one.

Network Address Translation Design and Implementation Abstract—This is the final report for a research project covering network address translation (NAT). Research topics include: the history and necessity for NAT‚ overall design‚ implementation‚ the different types‚ and examples of its use. Keywords—NAT; networking; project; research Necessity IP addresses were originally designed to be globally unique. In an IP network‚ each computer is allocated a unique IP address. In the current

After designing a network‚ there are some tools that will be needed to help monitor network bandwidth and traffic. Monitoring these two areas of a network can provide a network engineer with information about how much bandwidth the company actually needs. This can help to save the company money‚ because they will know exactly how much bandwidth to buy from their ISP. Monitoring network traffic is just as important as monitoring bandwidth‚ if can help to prevent degrading application performance.

LANs: Local Area Networks Local Area Networks also called LANs have been a major player in industrialization of computers. In the past 20 or so years the worlds industry has be invaded with new computer technology. It has made such an impact on the way we do business that it has become essential with an ever-growing need for improvement. LANs give an employer the ability to share information between computers with a simple relatively inexpensive system of network cards and software. It also
