Registry Cleaners Why do you need one?

The registry is the place where your computer stores the configuration information about your computer and your installed programs so that your operating system can use them.

Maintaining the registry is an important step in keeping your computer healthy. Registry problems can include slow performance, computer crashing, and the annoyingh Microsoft Windows error messages.

If any of these describes you as a computer user:

- Has old drivers on their system that have not been removed.

- Installs or uninstalls software very often.

- Have third party programs running such as Spyware and Adware (you can't stop these from being installed)

- Remove software by deleting them from the Program Files folder.

- Installs or Uninstalls hardware.

Then you absolutely need to be repairing your Microsoft Windows registry regularly! All of the above leave traces in your registry that will only hurt your computer in the long run. If you don't clean your computer to fix your registry than you are going to be in a whole world of trouble.

Make sure that you backup your registry before you try to clean or fix anything. Most registry cleaners have registry backup automatically for you, but be sure to check them out. Remember, don't try to edit anything in the registry yourself unless you are very computer savvy.

Why do you need a registry cleaner? Registry cleaners are important because it protects your PC from harmful processes. Is your computer slowing down for no apparent reason?

Computer Networking Fundamentals

A computer network is a collection of two or more computers with communication between them through a medium. The communication medium can be through radio waves, wires, infrared, optical fibers etc.

Computer network is an integral part of our daily lives, with the most important reason being that of communication. The use of computer networking is to share resources like fax machines, printers, modems, files etc., and its other uses are database server, computer server, email, chat, internet etc. The computer to which the resources are attached is called the server and the other computers that access the resource are called clients. In peer-to-peer computer networks there are no servers.

The sharing of fax machines, printers, and modems amongst many computers and users reduce the operational cost. A database on a computer network is a very important application as it stores and runs many important data and jobs. Emails and chats can be used for instantaneous communication and sending of files on a computer network.

The computer networks are classified, depending upon the size, as Local Area Networks (LAN), Wide Area Networks (WAN), Metropolitan Area Networks (MAN) and Personal Area Networks (PAN). The topology (topology is the way the computer networks and network resources are connected) of the networking can be classified as Bus Network, Ring Network and Star Network.

The networking hardware basically consists of wiring, network cards and a hub. Computer network cards are required so that one computer can understand what the other computer is "talking". Network cards have a unique MAC address to identify computers on a computer network. Hubs connect all the computers in the network. Hubs can also be used to connect to other hubs to increase the size of the computer network. Two computers can be connected using Ethernet cards or phone lines or power lines for communication, with hardware kits available at roughly a cost of $100.

As the number of computers in an office or a home increases, so do the number of cables, so wireless networking is a viable solution. In wireless networking radio transreceivers or infrared signals are used to communicate between computers and devices. Examples of wireless networking include Wi-fi and Bluetooth technology, though there may be security issues involved in wireless networking. However there definitely is a stronger preference towards wireless networking nowadays among consumers.

Computer networks have added a new dimension to the 21st century. Today the cyber world is much faster and wider than the real world. This has all been made possible due to computer networks. Computer networks have revolutionized business, communication, travel, research, defense, society and almost all human endeavors. The evolution of computer networks has helped the technological revolution take a big leap forward.

Peer-to-Peer and File Sharing Services Market 2007 - 2011

This report provides an overview of the Peer-to-Peer and File Sharing application services market. It details the status of the market today, as well as the migration through various stages of service integration and unification. The report covers all of the major approaches to IP-based applications service development and provisioning currently in the marketplace.

Service providers are in the midst of a gradual evolution from circuit-switched infrastructures to IP-based packet-switched infrastructures. While much of this evolution to date has taken place in the transport and access parts of the network, there are now enhanced services that are being developed and refined. In particular, the architecture of—and market for—next-generation enhanced services is beginning to take shape.
