Netbooks are little computers that are receiving big attention these days. Netbooks are actually mini-notebook computers with limited applications. They are designed to extremely portable, allowing internet use while out about (hence the "net" in netbook).
A netbook has a screen size of twelve inches or smaller and is very light-weight, generally less than three pounds. These energy-efficient mini-computers are perfect for email, chat, Web surfing or even movie watching. Most designs out now run Windows XP or Linux operating systems and are not intended for extensive data storage or complicated programs like Photoshop or 3D games. However, at less than $400 they may offer the perfect solution for consumers who want the newest gadget at a reasonable price.
It is the price that is posing a problem for manufacturers. It was likely that the netbook was created to complement the notebook computer; a consumer would want both to serve different purposes. But as the economy has gotten tougher, people are buying the cheaper netbooks at a faster rate. "... the low price tag that makes them such a hit these days means less revenue and profit for PC makers than what their full-size counterparts produce," said tech columnist Dan Zehr.
Last fall, of the top-selling laptops on Amazonover half of them were netbooks. An analysis on Barrons.com noted netbooks "could dent Macbook sales." This was particularly true during the back-to-school and holiday shopping periods. Of course, sales of iPhones and Blackberries are not being impacted in the same way as notebook computer sales, as they hold a different niche in the market.
So are netbooks worth the hype? That depends. If a consumer is looking for a powerful machine to be able to perform typing-heavy applications on-the-go, he would be better served sticking with a laptop computer. John New, senior manager for global product marketing at Dell Inc., said the netbooks work nicely for portable entertainment, but they are not intended for creating content or long periods of use.
That may be the netbooks biggest problem. While they offer a longer, more in depth Web experience than a smart phone, it is considerably shorter than a laptop computer with a larger battery capacity. The netbook allows use between 30 and 45 minutes, which is significantly less than most plane rides.
If the little computer with the little price tag does prove too irresistible to pass up, there are a few things to consider when purchasing a netbook. First, the price is budget friendly, but the consumer should make sure the netbook is user friendly for his individual computer needs. It's not a great price if it sits unused. There are choices on operating systems, so the consumer should make sure they understand how to use what they are getting. Finally, try several out to make sure screen and keyboard size make for comfortable use.
Also, as PC manufactures and retailers are adjusting for the netbooks popularity they are offering deals with notebooks and netbooks packaged together. They are not exactly on par with two for one deals, but it may be the best deal in the long run.

When it comes to buying computer hardware and components you need to know what are buying. In other words, don't just spend money so you can get something in your hands. Instead, make sure you know exactly what you are getting, how much it costs, and what else is available in the same price range. You may learn that your first choice is not the one that you want to stick with.
When you buy computer hardware and components online you have the ability to read reviews before making a final decision. This is very important because a review can sway you in one direction or the next.
For instance, a positive review on an LCD computer monitor may be all you need to make a decision to buy. But what if you read a bad review? In this case, you will probably want to continue your search to ensure that you don’t waste your money on something that is not what you are hoping for.
Remember, price does not always matter when buying computer hardware and components. You may think that spending more money on a particular piece of equipment is a good idea, but this is not always true. Higher priced products often times offer better value, but don’t get caught up in this way of thinking. You need to research every option, regardless of price.
If you don’t know what you are buying you should hold off for the time being. When it comes to shopping for computer hardware and components you cannot afford to make a mistake. You want your money to work for you, and you can do this by purchasing the product that offers the best value.

Computer viruses are executable programs that replicate essential software and destroys or pilfer data.
It is difficult to trace viruses until after it destroys software and data. Computer software becomes corrupted and document files erased from the system. The virus infects other computers and networks, resulting in software failure. Viruses also lead to software inconsistency, breakdowns and information loss.
Apart from virus problems, internet users face the risk of bogus ideas and dubious websites. Computer users are cheated through auction, online business and lottery schemes, credit card and identity theft. Virus types capable of infecting computers are classified below:
>> File infecting virus: that attaches itself to files and alters executable software.
>> Boot-sector virus: Boot sector software, available with executable instructions, works immediately after switching on the system. This virus destroys boot-sector data; therefore the system collapses.
>> Master boot-sector virus: works similar to boot-sector virus and attaches itself to removable disks, networks and hard-disks.
>> Polypartite virus: Program software and boot area infection are traits of this virus. Both boot-sector and programs should be removed.
>> Macro virus: attaches itself to user-created documents with software like MS-Word.
>> Trojan Horse virus: steals or corrupts files from computer. It spreads through email or software downloads.
>> Worm: replicates individually with worm-infected documents.
>> Virus Hoax: are threatening emails to frighten users about viruses and malware.
>> Metamorphic and Polymorphic codes: This virus alters its signatures and frequently mutates, making it unrecognizable. Brain or Ashar is supposedly the earliest virus in computer.
The internet and floppies were responsible for the spread of viruses.
Many software developers for piracy protection created and spread viruses on duplication. Adware is often spyware or shareware and, on installation, intrudes into the user’s privacy by displaying downloaded ads automatically. If the advertisement should be removed, the user must purchase the licensed software version.
Antivirus software is used in computer systems to eradicate viruses. The scanner identifies viruses with the help of virus signature files. The software distinguishes and removes memory, boot-sector and macro viruses, often deleting or quarantining infected files.
When viruses attack the computer, data and software backup, curtails the harassment and tension caused due to loss of vital data. Normally recovery from virus attack is possible after backup restoration. Floppies, CDs and pen-drives spread viruses. Hence ensure that you utilize scanned storage devices.
Regularly scan emails with updated antivirus software. Firewall software prevents internet viruses and spyware from accessing confidential data. Firewall downloads and antivirus signature file downloads keep the computer virus-free.

USB (Universal Serial Bus) is a low cost interface connection. It is now the most common computer connection with many device such as keyboards, printers and digital cameras using it as standar.
As the number of compatible devices has grown the need to easily access them has also increased. This has meant many users now need to expand and extend the USB connectivity of their laptop or desktop computer.
Expanding allows devices to be shared, split and accessed by more than one computer or enabling a computer to connect to multiple USB devices at the same time. Expanding overcomes the problems of the limited number of USB ports often supplied with modern computers, especially smaller laptops and netbooks.
Extending increases the distance USB signals can be sent so a computer doesn’t have to be closely situated to the peripheral. This combats one of USB’s major limitations in that the standard maximum recommend length for a USB cable is 5m due to performance restrictions.
However, for some applications for example interactive whiteboard installations, 5m is not always enough so signals need to be extended.The most common method of expanding USB is through the use of simple USB hubs. Hubs allow multiple USB peripherals to be connected to one USB port. Hubs in turn connect to a host computer transmitting all connecting signals to it.
The problem of port congestion is then solved as hubs generally have anything from 2 to 8 ports. Hubs are commonly free standing but are also built into devices such as monitors. USB switches expand peripheral connectivity by allowing them to be shared with multiple computers.
They are a cost effective solution especially useful for devices which need to be accessed by more than one computer, such as printers. They eliminate the need for duplicate devices and multiple cables. Switches alternate between computers as the users decide who has access to the equipment at that particular time.
USB sharing hubs combine the functionality of both a hub and a switch and can serve multiple USB devices between a number of computers at the same time. Just like switches, sharing hubs are ideal for larger, more expensive equipment that needs to be accessed by more than one person at a time, but with the capability that allows users to do this simultaneously.
As with expanding, extending USB can also be achieved using a number of methods. A simple way of extending USB is by using extension cables. USB extension cables are useful for extending devices over shorter distances and typically max out at around 3m in length. The ‘plug and play’ capability of extension cables makes them a simple and easy to use solution. They work with both smaller and larger devices such as card readers and printers. USB extension cables are ideal for use with wirelss dongles or with products that have built-in USB cables.
A simple, cost effective way to extend USB over very long distances is by using Cat.5 USB Extenders. As their name implies, these devices use standard Cat.5 Ethernet patch cable to make the long distance connection.
A transmitter is connected to a computer via its USB port while a receiver connects to the USB peripheral at the opposite end. The two units are then connected using Cat.5 cable. Commonly used with devices such as interactive whiteboards, extenders are a great solution for connecting devices further away from a host computer than an extension cable would allow.
Distances of up to 50m can be achieved; however, USB 2.0 is not usually supported so devices are limited to USB 1.1 performance of up to 11Mbps. Cat.5 USB Extenders are probably the cheapest and easiest solution for connecting a USB device and host computer over great distances.
Perhaps the ultimate form of USB extension is USB over IP servers which allow USB devices to be connected to a network. Equipment such as a standard USB printer can be transformed into a shared network device as the server provides an interface between the device and a network. It simply connects the device to a network via Ethernet so the device can be used by anyone on the network wherever they are in the world!
