The notebook computer’s main battery is not the same with its smaller battery which all computers have to backup the BIOS configuration or run the computer clock. The notebook… Read more
Wireless communication methods and services have evolved rapidly in the recent times and are vastly being adopted in various communication networks. Since the advent of wireless media and their application, their efficiency has resulted in an explosion in wireless networking giving rise to more reliable, cheaper and easy-to-use services. These growth trends are likely to continue in the coming times and expectantly at an even greater pace. To give a perspective, most countries throughout the world experience a cellular subscription increase of almost 40% every year. This increasing demand itself guarantees that wireless networking is a robust data and information… Read more
Typically a network is a collection of devices that are communicating which each other. The communicating devices do not necessarily have to be computers only. The activity of communicating or conveying information between different computers or similar computing systems relies heavily on the science of computer networking. Many fields of study make use of this intelligent and advanced branch of computer engineering. It encompasses many mother fields that are concerned with the technology of electronic communication. This linking employs the use of a variety of communication media depending on their inherent properties and characteristics and also the purpose and the… Read more
When computer networks first evolved, their usage was limited primarily to universities and medium sized organizations or companies. The basic purpose was to enhance the research facilities in an institute or very basic electronic communication such as e-mail or to share certain common devices in a network such as printers, fax machines etc. This limited exposure did not render these networks highly probable to network attacks and confidential data to be stolen and hence did not require any special security measures and procedures. With the boom in network industry, where the average count of its consumers has gone from a… Read more
Many a times network administrators experience problems of computers not connecting to the network and other similar problems. To resolve such issues it becomes necessary to troubleshoot the network and find the cause and appropriate solutions. Basic network troubleshooting involves determining whether the network card is connected properly or not. You can easily check this by taking a look at the LEDs where the network cable is attached to your computer. These LEDs indicate whether the cable has been connected properly or not. A network card with a stable green light is usually a representative of a properly connected cable…. Read more
If you are using a wireless service then it is crucially important to use encryption methods and other protection providing soft-wares to prevent hackers on from the outside internet world to break into your network and gain access to your confidential information. Even if your router is equipped with a built-in firewall, it is still recommended that the user should install software firewalls on the computers themselves for added security. Moreover, if you wish to keep your internet traffic private and secure then always ensure that your computer’s firewall is turned on before you log on. Also ensure that windows… Read more
