The advanced server versions, like Windows Small Business Server 2003 R2 enable the user to handle the accounts and passwords, allow or limit the access to shared resources, automatically support the data and access the business information remotely. For example, a file server is a machine that maintains files and allows clients or users to upload and download files from it. Similarly, a web server hosts websites and allows users to access these websites. Clients mainly include computers, printers, faxes or other devices that can be connected to the server. By using a server, one can securely share files and resources like fax machines and printers. Hence, with a server network, employees can access the Internet or company e-mail simultaneously.

Besides, they hamper the security of important documents stored in your system and crash your system’s RAM (Random Access Memory). Signs such as an extremely slow system, abrupt reboots, blue error screens, a lot of undefined and random errors, and a large number of pop up windows opening simultaneously, indicate a possible virus or a spyware attack!

Cloud Computing for Small Businesses

The entire tech world seems to be floating on the clouds these days. Nope, we aren’t talking about a sudden boom in this field where everyone’s riding on a high. Instead, we’re talking about the new rage in the industry, cloud computing. This new technological breakthrough has ushered in a sea change in the way the IT sector works, and is an absolute blessing for small start-ups.

Web Container Vs. Web Server

Though it started out as a pure information resource, freely accessible to people all over the globe, the world wide web has evolved to offer much more today. As opposed to the passive information repository it was before, now Internet offers many services ranging from online banking, social networking, email, e-shopping, video sharing, online auctions to multiplayer gaming and much more, which are all made possible due to the advances in web technologies.

All these services are enabled by web servers, which host the pages and handle all the client queries. Associated technologies like web containers are used to extend server functionality and provide additional services through usage of Java servlets. In this Buzzle article, I present a web container vs web server comparison which clarifies the differences between these two commonly used web technologies.

What is a Web Server?
The whole TCP/IP (Transmission Control Protocol / Internet Protocol) based Internet architecture is based on a ‘Client-Server’ model. Every time you type in a web site address in your browser, a query is sent to the web server, hosting the pages.

How an ISP Actually Works

ISP stands for Internet Service Provider. These are the agencies that help you connect your computer to the Internet. The first cross-country link through the Internet was established in 1970. But, till date there are many people who are not aware of the working of the world wide web. The answer is the ISP, which connects you to the Internet.
What is an ISP?
As mentioned above, ISPs are agencies that provide access to the Internet. They can be either privately owned, i.e., by an individual, or they can be group owned, i.e., by a group of individuals/community. The Internet is a huge network, formed by the interconnection of many small and big networks throughout the world. There is a mind-boggling quantity of data on the Internet, but it would have been pointless if we didn’t have access to all this information. ISPs are the agencies that bridge this gap between us users, and the Internet. They provide the technology that is necessary for us to be able to access this information, as well add information and data on the Internet.

A simple analogy should make the concept easier to follow. Imagine you are in a huge mall where

Computer Hardware Repair and Maintenance

What is computer hardware? Hardware components like the monitor, keyboard, CPU (Central Processing Unit), mouse, and other I/O (Input-Output) devices constitute a computer. The working of the monitor, keyboard, mouse, and I/O devices depends largely upon the CPU. Due to some minor causes, like loose connections or dust saturation, any of them can stop functioning.

Faults occurring in the CPU are most hazardous, as it has a very complicated structure. The CPU is an assembly of the motherboard, hard disk drive (HDD), random access memory (RAM), compact disc-read only memory (CD-ROM) drive, and the floppy drive. Unless you are well-acquainted with the CPU hardware, it is extremely difficult to pinpoint exactly where the fault has occurred. If any one of these components fail to perform, there are a few repair tips that can be followed. In order to view the circuitry inside the CPU, its casing has to be removed.

The entire functioning of the computer depends on this component. The processor chipset, that performs all the logical operations of the PC, is embedded in the motherboard. Ribbon cables, power supply, CPU, and RAM are the things to be checked first on the motherboard. Check if any of the
