A computer is an exclusive component that has enslaved man throughout the globe. People have come to a point that life would come to a standstill if there are no computers in this world. Everything is centered on the use of a computer and the internet. Computers are of various types from big to small screens, flat to round shaped screens etc. People have their own choice of computers whether laptop or desktop.
With the fast moving world today the laptop has found a very high position in the computer world, but this is meant only for light jobs like checking mail and making a few entries that are essential while being out of the house or office. But if people want to do heavy work then the desk-top is the ideal choice, especially in big offices where laborious jobs are required to be accomplished.
Top reasons why a desktop is the best
A few of the most well-known benefits of a desk top include first of all the price. Since the desktop computers are not portable their price is less, but they are stronger than the portable ones that are highly priced because of its portability. One does not have to seek the assistance of a service centre to replace a mouse, keyboard or monitor. But since the portable models have everything built in, it is mandatory that it is done by a professional repair assistant. Hence maintenance costs too are low with the desk-top.
Since the computer is sturdy and heavy they can be over ruled in case of a theft in the home, whereas the portable is the first attraction to an intruder. Since the portable ones are carried from place to place often the danger of it being dropped is high, unlike the desktop computer that remains stable in one place.
Over heating of a desktop-computer is ruled out since it has a lot of vents at the back of the monitor, whereas the portable one has just one vent at the back and the remaining are under the keyboard which is placed on a table, thus blocking the computer and resulting in over heating of the machine.
A desktop is definitely more useful than a laptop
A laptop is useful tool in many ways, especially when you are travelling and have a lot of urgent and important jobs to be accomplished, the desktop can never replace a laptop. But this does not always happen, or even if it does, if one is into a big business one would use the laptop and the mobile to leave messages to the office staff to do the pending jobs. The office staff would definitely use the desktop computer that is more economic and easy to handle. It is sturdier too and easily accessible.
A desktop computer is cheap, sturdy and long lasting with less to zero maintenance costs. If the user has an idea of using this exclusive machine properly it would prove to be the greatest asset. With a desktop computer at home children and home makers have a free access to do work on it without fear of it getting destroyed.
Children love to play computer games and surely no parent who is into business would lend the laptop to a child to play games. The desktop-computer is a ready and inviting appliance for the entire family.

In a perfect world no one would be able to infiltrate our home computers and mess with our lives, but this isn’t a perfect world. Every home computer needs to have home computer security measures installed to protect it. So don’t put it off any longer. Start doing some research so that you can choose the right home computer security for you.
What you need to Know about Home Computer Security
Statistics would surely prove that with the millions of people online every day, at least a handful of them are going to be hackers. Hackers are fiendish individuals who have computer abilities to access the computers of others and spread viruses which are a menace to the computer world. Viruses have done their job in eliminating crucial data and damaging computer hard drives all over the world. People can now fight back, however, by purchasing security systems for the computers they have in their homes.
There are two good ways to get home computer security. One is to buy it on CD-ROM which can be installed on your computer. The other way is to purchase it online and then download it into your PC.
Don’t be fooled by websites which offer you “free” security software. There’s bound to be an ulterior motive behind that offer. Besides, if you download their software you’ll also get a “free” load of spyware which will track your use of the internet without your knowledge.
When you install your computer security software, be sure to carefully set your preferences. Otherwise you may be installing firewalls which will block you from internet content you want to see.
For people who are still using dial-up internet connections, it will take a substantial amount of time to download home computer security software off of the internet. An option you have is to buy the CD-ROM, because it will download much faster. If you do decide to go with the internet download, you may want to wait and run it while you’re at work or sleeping so that it won’t interfere with your use of your computer.
Do some research into the features and prices of various home computer security packages which are available. You can also ask family and friends what they recommend. It won’t do to be too chap when buying software, because you need to have software you trust to protect your important computer files. No matter what you choose, you’ll always be glad you took steps to protect your home computer.
Computer icons are a modern software tool; they were introduced into the computing world in the late twentieth century. Icons are small pictures which appear on a computer screen and assist the user with programs and functions – they represent the various files, folders, applications and devices on a computer’s operating system. There are many different novelty computer icons and they are incredibly appealing – computer users would much rather be welcomed by a brightly coloured (and sometimes animated) icon that a boring blank screen with basic prompts.
Apple claimed to have invented the icon in the early eighties but this is untrue. Rather, a group of programmers at Xerox developed the world’s first commercial interface using icons in the 1970′s. The concept behind the computer icon is a rather simple one: the icon (or symbol) represents a particular feature of a program and what that program does. For example, the folder icon on a desktop represents a place to store files and a notepad icon represents the folder where notes are kept. Other common examples are an icon depicting a picture of the world for Google Earth, and a picture of a bin with a recycling symbol on the front to access … yes, you guessed it … the recycle bin! These icons may be found on the desktop and in the main toolbar of your computer.
Although Xerox invented the concept of the icon, Microsoft quickly took up the idea and incorporated the computer icon as an integral part of their Windows program. Perhaps the biggest advantage of introducing icons to Windows has been the user-friendly element: people feel much more at ease clicking on an icon to access the program they want, rather than having to type in confusing commands or follow tedious prompts. This is especially true for novice users.
Since the inception of the computer icon, the world has gone icon crazy. This is true of the usual icon which represents the many functions and programs on a computer, but the phenomenon of social networking has made a new type of icon extremely popular. These include ‘smileys’ and the ‘emoticons’ that people often use on blogs and social networking sites to demonstrate their mood. There are thousands of sites on the internet offering visitors the chance to download the many different types of computer icon for free. Some sites even have downloadable programs which allow users to design their own icons.
A computer icon is made up of tiny pixels, and they range in size from 16 x 16 pixels to 128 x 128 pixels. Some advanced machines can feature icons up to 512 x 512 pixels in size, but icon size depends on graphical output device – when this is small, the icon is small. People with poor eyesight may need to adjust the pixel settings of a computer icon to suit their visual needs.
There is no doubt that the computer icon has grown massively along with technology, and today an icon can represent anything as specified by a user.
What time is it in Los Angeles? With just a few taps on the keyboard or maybe even a click of the mouse, we could easily find out what time it is in any part of the world. The emergence of the computer age has paved the way for different software like the network time protocol (NTP), which can synchronize with a wide array of public servers that are available online.
Unfortunately, even with the advances of technology, our computers still have their limitations. They can easily be shut down by blackouts and power failures. Even worse, they can hang or crash because of a system glitch or a virus. In fact, they are prone to catching viruses that make them useless and dysfunctional even though we have already installed a lot of anti-virus software just to make sure that we don’t lose our important files. We even need to back up everything that we have worked on just to make sure we don’t lose them after a major reformatting. Having another way to tell the time in other time zones is just as important as backing up your files.
If All Else Fails, Go Back to Basics
When the miracles of the computer age let you down, world time zone clocks can save the day. Most world time zone clocks have a revolving dial that can be set to tell the time anywhere in the world. Some digital clocks can be set to show the time in any part of the world.
By using world time zone clocks that do not need internet connection to function, there is no more need to worry about server problems. As long as the world time zone clock’s power supply is checked and replenished regularly, there is no danger of missing phone meetings and important deals because the time has stopped in the office.
Not Just A Time Piece
World time zone clocks do not just tell time, they can serve as perfect additions to any workplace. By getting the right piece, one can accentuate his office, giving it a more professional and elegant touch. A computer can never take the place of a beautiful glass world time zone clock with a satin rose base. With a time piece such as world time zone clock, the designs can be limitless and can beat a uniformly shaped computer any time of the day. In fact, some world time zone clocks even come with an eight-digit calculator and an FM radio with a telescoping antenna.
The Best Traveling Companion
Unlike bulky computers, world time zone clocks can be taken out of the office. Because most of them are very compact and can easily fit a person’s palm, they can easily be slipped into a purse or suitcase. Also, unlike portable computers, there is no need to look for wi-fi sites or wait for it to log on. Sometimes, going back to basics can make things less complicated

Other tools within the suite will run a check of sub-systems, network card information, and other components while looking for unsavory characters in the form viruses, malware, spyware and so forth.
A registry cleaner is a common PC diagnostic software program; some consider it essential to any user no matter what level their expertise. A registry plays a key supporting role to the Windows operating system. It serves as a container for data that the hardware and software installed on the computer need to operate seamlessly together.
On occasion, nefarious bits of unwelcome data will try and hide in the registry, causing havoc in the form of error boxes, system freezes and outright crashes. A registry cleaner will stop at nothing to track down the violating data and dispense with it to make it safe again for your PC to resume its normal operating speeds.
PC diagnostic software can be worth every penny spent, especially if it saves you from a complete and total system failure. All it takes is just one time for this to happen for you to start sweating bullets wondering if you’ve lost everything you’ve been working on. It’s software that is for the most part easy to use and can tell you a lot about how you’re system is operating and what you might want to do so that runs better. Talk to you fellow PC users and see what they use for their diagnostics. And read reviews online. That will make it easy to choose the software that’s right for you.

Directories, in computer science parlance, are the listings of files, documents, and other directories within a file system. Most people think of directories as electronic folders that contain various files.
A directory is one of the first concepts anyone learning computers encounters aside from files. He or she soon learns that these files are all contained in a listing called the directory.
Who could forget the early DOS days when the command of choice was “dir c:\”?
A directory contained inside another directory is called a subdirectory of that directory. Together, the directories form a hierarchy, or tree structure. Organization of file systems into such makes for a more organized hierarchy.
It allows the files to be grouped according to the owner’s desire, and presents a more organized alternative to just having all the files dumped into one listing.
Microsoft Windows and the Mac OS use folders to represent directories. This helps the user to visualize the directory as a folder that contains many papers and documents. The papers and documents represent files in the system.
With this tree hierarchy Windows and MacOS supports, one cannot just simply access a file from any point. He or she must access the file using a path.
For example, if the user is currently browing folder x, the only files he or she can access are the files listed in that folder. To access files found in folder y, the user must traverse the path from one directory to its subdirectory until he or she finally accesses the folder or directory that contains the file needed.
Historically, and even on some modern embedded devices, the file systems either do not support directories at all or only have a flat directory structure. This means subdirectories are not allowed.
There is only a group of top-level directories that containing files. This is similar to just having one directory for all your files.
The topmost directory in a file system is called the root directory. These directories contain other directories that are fittingly called subdirectories. The subdirectories may also contain subdirectories. This can go on and on indefinitely.
Depending on how an operating system supports directories, filenames in a directory can be viewed and ordered in various ways. They can be viewed and sorted alphabetically, by date, by size, or as icons in a graphical user interface.
The word directory is also used in computing and telephony with a different sense: a central repository of information related to management of a computer or a network of computers.
This includes data on applications, hosts, users, network devices, security credentials and more. This kind of directory, as opposed to a conventional database, is heavily optimized for easy reading.
Everybody who uses computers uses directories. Only, he or she may not notice it, or may not be aware of how this concept works. Most people make the most out of the directory concept by using it to organize their files.
Think that every person that has been to high school knows what ‘the’ Trojan Horse is. It’s a really big wooden horse that the Greeks used to infiltrate the city in the Trojan War. They stuffed some men inside the horse, so when the Trojans would take it in their city, they could come out and wreck the place. Well, in the computer world, a Trojan Horse does exactly the same thing. That probably explains the name.
A Trojan Horse is a small application that is formed out of two parts, a client and a server. The client is being used by the attacker to gain access to the computer. The server is installed on your computer (usually without you knowing it), if you open an infected file. When the server is successfully installed anybody can gain access to your hard drive with a simple program. Unfortunately, this program is so simple, that every person can use it and this makes the chance of getting hacked only bigger.
Now you might ask yourself, how the owner of the client knows if you installed the program on your computer. This can be tracked with your IP. Your IP is a unique number that you receive from your Internet Provider that marks your internet connection. Any person with a Trojan Horse client can search for your IP and find your computer. That person doesn’t even have to be the same as the one you downloaded the Trojan from.
A Trojan horse can do a lot of funny stuff (for the hacker), but it can also do serious damage to your computer. Your DVD-drive could be opening for no reason, a couple times in a row. If you’re talking the microphone, the hacker knows exactly what you are saying. The hacker can play audio files, view images, send messages to the victim, delete files, block the keyboard and a lot more! If you really have a bad person on your tail, you’re system can be completely dead in a matter of minutes.
Now what can you do to prevent that you get a Trojan Horse? Well, the best thing you can do is having a decent Anti-virus program installed. If you download a Trojan Horse by accident, the program should notify you and delete it. On the other hand, preventing that you get a Trojan Horse is better than deleting it afterwords. You just need to be careful what you download to your hard drive. If you don’t know where the file comes from or who the owner is, don’t open it. A really famous way of spreading trojan horses is through email attachments. If you open it, you’re already too late. Just make sure that you know the person that sent you the email before you open it.
The conclusion of this article is that you have to be really careful with what program or file you open on your system. Check if you really know the source of it and if your trust it. To be absolutely sure you don’t get infected, install a decent Anti-virus.
