Server Monitor

Sometimes you are in a need of monitoring the status of your web applications. Simple Server Monitor is a solution for this problem. It is powerful, of low cost and user-friendly server monitoring program that can continually monitor the status of your servers and web applications. When it detects any network uptime losses, then it can alert you with many methods. These alerting methods can be one of the following:

Simple Server Monitor can alert you with pop-up messages, e-mail / cell phone alerts, desktop audible alerts and external application launch. You can also perform its settings in a manner that you want. When you are using the alarming methods, then you can also stay connected with networks and servers from all over the world. In this way you can be aware of maintaining server uptime without losing your mobility. Here uptime deals with the availability of the network. If a website is designed for the purpose of providing continuous service to its customers and clients throughout the world, then its uptime should be higher. If the uptime of any website is higher, then it is more successful in the internet marketplace.

If any website has lower uptime, then it can refuse hundreds or even thousands of visitors. If you want to increase the website reliability then it is necessary that you should monitor the server uptime. Simple Server Monitor also gives the following benefits:

It provides you up-to-the-minute network monitoring. Its performance charts monitors the server operation. Simple Server Monitor has better testing as compared with a server ping. It can be connected to a service and logs on. It provides unlimited e-mail support and free minor updates.

What is LAN, WLAN, WAN, MAN, SAN, CAN, PAN and GAN ?

Computer networks are bunch of interconnected PC or computers that facilitate the exchange of data or some other purposeful work. The first computer network to be designed was the "Advanced Research Projects Agency Network" (ARPANET) for the United States Department of Defense in the late 1960s and early 1970s. From then on, numerous new network technologies have been developed.

Computer networks can be classified into different types based on their scale of operation. They include:
  • LAN: Local Area Networks cover a small physical area, like a home, office, or a small group of buildings, such as a school or airport.

  • WLAN: Wireless Local Area Networks enable users to move around within a larger coverage area, but still be wirelessly connected to the network.

  • WAN: Wide Area Networks cover a broad area, like communication links that cross metropolitan, regional, or national boundaries. The Internet is the best example of a WAN.

  • MAN: Metropolitan Area Networks are very large networks that cover an entire city.

  • SAN: Storage Area Networks help attach remote computer storage devices, such as disk arrays, tape libraries, and optical jukeboxes, to servers in such a manner that that they appear to be locally attached to the operating system.

  • CAN: Controller Area Networks allow micro controllers and devices to communicate with each other without a host computer.

  • PAN: Personal Area Networks are used for communication among various devices, such as telephones, personal digital assistants, fax machines, and printers, that are located close to a single user.

  • GAN: Global Area Networks support mobile communications across an arbitrary number of wireless LANs and satellite coverage areas.

  • INTERNETWORK: Internetworking is the process of connecting two or more distinct computer networks or network segments through a common routing technology.

Computer networks are an integral part of our lives. It is only because of networking that telephones, televisions, radios, and the Internet are at our fingertips.
