This article describes how to use the Windows XP Encrypting File System (EFS) feature to store files in an encrypted format on your hard disk. Encryption is the process of converting data into a format that cannot be read by others. You can use EFS to automatically encrypt your data when it is stored on the hard disk. The Encrypting File System (EFS) is a file system driver that provides filesystem-level encryption in Microsoft Windows (2000 and later) operating systems, except Windows XP Home Edition, Windows Vista Basic, and Windows Vista Home Premium. The technology enables files to be transparently encrypted on NTFS file systems to protect confidential data from attackers with physical access to the computer.

One of the most widely used network topologies (and the one most often used in medium to large Local Area Networks) is the bus network. A bus network uses a cable to which are attached all the network devices, either directly or through a junction box of some sort. Each device uses a transceiver to connect to the backbone. The manner of attachment depends on the type of bus network, the protocol in use, and the speed of the network. The main cable that is used to connect all the devices is called the backbone. Each end of the backbone (also called a bus) is terminated with a block of resistors or similar electrical device. Most large TCP/IP networks used by Linux are bus topologies.

In recent years, Microsoft has taken a pummeling in the Web server business. At one time, IIS and Windows NT Server 4.0 was the most popular commercial Web server platform; today, Windows 2000 Server and Windows Server 2003 are fighting against a wave of free and inexpensive versions of the Linux operating system and Apache Web server software. Microsoft argues that such servers don’t come with the support that a multi-billion dollar company like Microsoft can provide; fans of Linux/Apache solutions say, "Who cares?" As a result, Microsoft has worked hard to provide a lower-cost version of Windows that’s optimized to be a high-speed Web server. Although lower-cost certainly doesn’t beat free, it does help close the gap and make potential buyers look at the additional features IIS offers, as well as the support Microsoft can provide. Microsoft’s lower-cost Web server solution is Windows Server 2003, Web Edition.

Whether it’s because you have made a call using a mobile phone, received a message on your pager, checked your email from a PDA or even just seen an advert related to it, we have all come across a wireless data or voice network!If a user, application or company wishes to make data portable, mobile and accessible then wireless networking is the answer. A wireless networking system would rid of the downtime you would normally have in a wired network due to cable problems. It would also save time and money due to the fact that you would spare the expense of installing a lot of cables. Also, if a client computer needs to relocate to another part of the office then all you need to do is move the machine with the wireless network card.
