 Computer viruses have been a sad reality for many years. The first PC virus was more of an accident than anything else, but it was a gateway to much larger endeavors all done in the name of destabilizing computers. The Macintosh computer was one of the first machines to feature a graphical interface and supported by proprietary software . Though these viruses are not as prevalent nor as damaging as PC viruses, as more people switch to Mac, its operating system has become a target for viruses as well. A Mac Virus? Let's take a look at a few of the different Mac viruses out there. In 1994, the INIT-29-B virus was born. This was a virus that could alter applications and system files. It would cause programs to crash at random though there was no specific control over the programs it would affect. Though it was limited, it could certainly be very annoying. July of 1995 saw a virus that would affect HyperCard stacks. While it would not affect your system files, it would spread to ...

 What will not or cannot be delivered via technology and PCs? Buying and selling are established. So, too, even enlightenment and awareness. It might seem far-fetched, but how far are we from touch, taste and smell over the web ? In fact there's already a means to convey human touch via the web - well, a form of it anyway. And we live in an age in which the entire ' Encyclopedia Gallactica' is available for an overwhelming number of individuals to browse, on their schedule and at the touch of their hand. That has never, ever been the case in before... All of the accumulated knowledge - not just of the human race, but of the entire universe for all we know - is available in some form online. (There's some ambiguity around that: turns out it depends on who is looking, and exactly what 'knowledge' they're looking for.) But up to now computer architecture evolved along a path that made it a "dramatic dialog" to use. HAL would have been a step in th...

 Technology has changed everything - even a small desktop PC has become more swift and durable as compare to the old ones. The communication and mobile technology has also brought a huge change in this whole world and we can say that the whole world as become a global image. Well, there are a lot of devices that we can discuss here but only because of less time I would like to discuss the history and classification of a computer along with its types. If we through the history of this electronic device then there was a time when this device was very huge and bulk in size. It also requires a lot of room and extra air conditioning to operate such type of devices. Now, these bulky devices have become more efficient and essential that it has become quite difficult for a common man to survive without these devices either it is a phone or a computing device. Below, few important categories of computer are mentioned along with their merits and demerits. Fast Super Computers: This type...

 The advent of the computer age may suggest a further step in the evolutionary process. The control of more and more of the natural world by our species indicates that we may be approaching the limit to further advances in this regard. The further advance of mans domination now resides in the increased development of his mind. But, this part of the evolutionary process, the advance in mans ability to think, has been aided by; and now may be surpassed by, the recent advances in computer technology. Now, our dependence on these machines has become total, as they are being incorporated more and more into the activities of our daily lives. The even more recent development of the internet has extended the evolutionary horizon even more dramatically, as all people in different regions of the world are becoming more and more involved with each other by communication over the internet . This computer involvement in daily living may be the evolutionary advance of the future, as the t...

 We live in a world of computers . Whether we like it or not, computers are here to stay and are going to be around long after you and I are long gone. I remember when I first started playing on the computer . Do you? I didn't know anything about them. Computers are one of those things where the more you doodle with them, the more you learn. Granted they can be intimidating at first, but the longer that you plug away at them, the better you'll get. (Just like anything else I suppose.) I started learning about computers late. My little cousins knew more about them than I did. What a shame. If I knew that computers would be that important as I grew older in life, I would of taken the time to learn more about them. For anyone out there that doesn't know much about computers , I recommend trying to learn as much as you can. I'm not saying be a computer expert or anything like that. Just learn the basics, Like sending an e-mail , basic typing, copy and paste, etc. When e...

The Web is a collection of interconnected documents and other resources, linked by hyperlinks and URLs. The Hypertext Transfer Protocol (HTTP) is the application layer protocol that links and provides access to the files, documents and other resources of the World Wide Web. The Web is a way of accessing information over the medium of the Internet. Web services, which use HTTP to allow applications to communicate in order to exchange business logic, use the Web to share information. Web documents also contain graphics, sounds, text and video. Compared to encyclopedias and traditional libraries, the World Wide Web has enabled a sudden and extreme decentralization of information and data. Many individuals and some companies and groups have adopted the use of "Web logs" or blogs , which are largely used as easily-updatable online diaries. Browsers Even before the World Wide Web, there were search engines that attempted to organize the Internet . As the Web grew, search engines...

 Internet sources differ in the kinds of information that are important for retrieval, and the model for each type of source reflects the information needed to retrieve that source. The Internet is a worldwide , publicly accessible network of interconnected computer networks that transmit data by packet switching using the standard Internet Protocol (IP). The Internet is a collection of inter connected computer networks, linked by copper wires, fiber-optic cables, wireless connections, etc. Web The World Wide Web is merely a service accessible via the Internet, along with many other services including e-mail, file sharing, and others described below. The Internet consists of the computers and networks that can handle Internet Protocol data packets. Over the course of the decade, the Internet successfully accommodated the majority of previously existing public computer networks. During the 1990s, it was estimated that the Internet grew by 100% per year, with a brief period of ex...

 What astounds me about the Internet is how it never ceases to surprise . Every now and again, and it seems more now than again, a web site or Internet application comes along and rocks the inter-web. A long time ago, Google came along and changed the face of search forever. The people behind these applications seldom anticipate the effect of their application on the rest of the world. I doubt that Bil Gates thought Windows would become the operating system it is at the moment. Sergey and Larry didn't thing Google would become the king of search and price of advertising on the Internet. Steve Jobs tried to conquer the world with the iPod, and to a large degree he has succeeded. What he built to support the iPod had become a powerhouse all in it's self. iTunes, has now been rated the third largest music seller in the world. They sell more music than Amazon . The reality of an Internet application is that when the developers put everything they can into it, to make it the be...

 Wireless security is an essential aspect of any wireless network. It is of great concern because wireless networks are highly prone to accidental security threats. A wireless signal can easily be detected by someone who is near to the wireless network and is equipped with the right receiver. Whether the wireless network is meant for home use or office use, security of this type of network is always going to be a major concern. Wireless networks are required to be secured completely. Sometimes security lapses occur accidentally. Somebody working on his/her laptop at a place within the range of our wireless network might receive the signals on his laptop accidentally or it can be done intentionally by the use of a receiver. Most organizations do not realize that how unsecured these wireless connections are for their organization if there is not wireless security in place. If the wireless connection is left open and unsecured, the important information which was meant for private ...

 s I was saying, the higher you are on search engines the more money you make. So, how will we accomplish that? Google has Google's LSI - Latent Semantic Indexing.... So we need to know how to make LSI work for us. A few years ago people could manipulate their position on search engines by method known as "Keyword Stuffing". They would "stuff" their websites with keywords while trying to discover perfect keyword density that would give their site a top ten ranking. Today, Google has developed more advanced algorithms , and only a few of Google's engineers know how they work. You will find various SEO (search engine optimization) tips on the net saying that you need to put your keywords in the title of your web page, in title of the post in tags...but even that nor a lots of visitors doesn't guarantee you higher position in search engines. Trough advanced algorithms and word association Google is able to tell if a page with a word "mouse" i...

  Linux OS was first created by a student from the University of Helsinki in Finland. The creator's name was Linus Torvalds and he had an interest which turned into a passion for Minix, a small Unix application which was later developed into a system that surpassed the Minix standards . He started working on the minix in 1991 and worked heavily until 1994 when the first version of Linux kernal 1.0 was released. This Linux kernal sets the foundation to which the OS of Linux is formed. Hundreds of organization s and companies today have hired individuals and used them to release versions of operating systems using Linux kernal. Linux's functioning, features and adaptation have made Linux and Windows OS's are excellent alternatives to other OS's. IBM and other giant companies around the world support Linux and its ongoing work after a decade from its initial release. The OS is incorporated into microchips using a proces s called "embedding" and is increasing t...

 Though electronic gadgets are extremely useful, they are not free from their share of shortcomings. One of the biggest shortcoming of gadgets like iPods is the fact that it has to be regularly charged. This is exactly the reason that such devices come with their own chargers. It is extremely important, because in most of the cases, iPods are not compatible to iPod mains charger of any other manufacturer. The importance of iPod mains charger as such can easily be understood. Imagine a situation when your iPod is out of charge and you don't have an iPod charger with you.
