Computer Buying Tips


Deciding whether to buy a Mac or a PC should be based on two main points: your budget and whether the computer is primarily for business or pleasure. Both types of computers are excellent for specifictasks, although if you are planning to go to work and bring your computer with you, you may need to consider what types of computers your coworkers will have to make it easier to swap files or compare notes. Here a few basic tips on how to choose the right computer for you.
Budget
There’s no debate—Macs are far more expensive than PCs. If money is a big issue for you, you’ll want to buy a PC. However, Macs aren’t overpriced. Unlike PCs, each computer is designed for maximum efficiency in both processing speed and ease of use. While PCs frequently crash and are vulnerable to spyware and viruses, Macs resist most viral attacks and operate at a consistently high standard with virtually no technical issues. If you can afford it, a Mac isan excellent investment which will work foryou for years.
Business
While Macs have always been the preferred computer of graphic designers and other creative individuals, for most corporate office work, PCs have long been favored over Macs. For this reason, PCs still dominate in most business settings.
Up until a few years ago, the major software designed for business suites, like the Microsoft Suite, was designed chiefly forPCs. However, the popularity of other Apple products such as the iPod and iPad has started to change the way Macs are perceived in the larger corporate world. Most business software now has versions available for both Macs and PCs. Because of their heftier price tag, Macs still have a long way to go in making a dent in the corporateworld, although in terms of functionality they perform just as well as a PC.
Graphically, Macs have richer displays and a Linux based operating system that makes them ideal for manipulating complex information such as layered graphical displays. Photoshop was initially designed for the Mac. If you are buying a computer for use in a professionally creative setting, your coworkers will likely also be using Macs.
Programming
Computer programmers are evenly split on whether Macs or PCs make better programming tools. The truth is, it comes down to a matter of personal preference. Macs developed a comprehensive suite of developer tools with their OS 10 which, if used properly, can help you get to the moon. PCs have always been oriented toward programming; in fact, the DOS/Windows interface was developed mainly as a way to stay competitive with the user friendly Mac interface. However, many programmers have complained that Macs are slower than PCs when it comes down to executing large amounts of freshlyprogrammed code.
Personal Use
If you enjoy playing video games in your spare time, buying a PC is probably the best choice. This is partly because PCs are easier to hook up to auxiliary equipment like television sets or other devices. Although USB ports are evenly distributed between Macs and PC, the higher data transfer portals of a Mac do not always adapt easily to most conventional televisions, making it difficult to quickly relay information between the two devices, whereas the higher data transfer portals of a PC are usually very adaptable to auxiliary devices.
If, on the other hand, you prefer to design or develop creative projects in your personal time, Macs are a much better choice. Because Apple has invested so muchtime in making the user interface incredibly easy to use, spending time creating music or drawing or editing movies becomes less about the computer and more about the activity; you forget you are using a computer, and can instead focus on the act of creation. PCs have a more rigid approach;it’s hard to forget that you’re on a computer.
Cloud Computing and the Future of Virtualization
Of course, with the tech community excited about the potential of cloud computing, computer memory is going to become less of an issue, with flexibility, mobility, and processing speed becoming increasingly important when making purchasing decisions. Mac’s suite of mobile devices are far better adapted to shifting between different geographical areas while also offering enough functionality to make themviable business tools. However, for now youshould buy the computer that best suits your needs, and plan on the inevitable: no matter what you buy now, in a few years it will be completely outdated anyway!

How to Protect Your Computer From Viruses


With millions of computer users browsing the web at any given time, there are plenty of targets for malicious coders. While computer experts don’t always know why coders choose to build harmful computer programs, the fact is that it happens all the time. Computer viruses can steal personal information, interfere with normal operations, attract spam and even shut down your computer’s hard drive. Protecting your computer is critical for browsing success.
Start With the Basics
Most computer systems come with security features already in place. For example, the Windows operating system is packaged with Microsoft Windows Security Center. When you first open, boot up and register anew computer, you should make sure that this program is functioning. It will give basic protection against spyware, viruses and malware. In addition, a basic firewall is built into this program, providing additional protection and stops for potentially harmful programs. Upon activation, don’t be surprised if your security system needs immediate updating. Software that protects your computer needs regular and consistent updating to stay useful. Viruses are constantly being generated and the several-month lag between when your computer was made and when you first started using it can mean that the database the security systemis loaded with is severely out-of-date.
Upgrade to Meet Your Needs
Many people operate computers for a long time with only basic protection in place. However, heavy computer users or those who have risky browsing habits can sometimes benefit from upgrading their virus, spyware and malware protection, as well as using a fuller-featured firewall; this is especially important if you use a networked computer system. Basic or free virus protection will still scan and update for viruses. Paid programs, however, offer more features, including ease-of-use and convenience features. The most important thing is to verify the publisher and make sure you are getting what is promised. Mostwell-known virus protection programs, such as AVG and Norton Security, have reviews available to help you make your choice.
Learn About Spyware Risks
Spyware creates risks that many computer users are not aware of. If you are only protecting against viruses, you could be leaving your computer open to damage. Most people are familiar with spyware that initiates and attracts annoying ad programs. Spyware, however, can be much more malicious as well. Your shopping habits can be tracked by spyware. While notexactly harmful, some people consider this a breach of privacy. The worst spyware programs interfere with normal operations and can even track what you type, sending personal information to people who want to steal your identity. Some spyware redirects your browser to different web addresses, increasing your risks of virus infection and fraud.
How Viruses Work
The main difference between spyware and viruses is how they are spread. A virus reproduces itself and attaches to any document that the computer sends, while spyware can be stored as a cookie or tracking code. A virus is most often found traveling with a piece of computer software, such as a document, picture or piece of music. When dealing with email, it is necessary to open an attachment to become infected, indicating that, in most cases, the computer user must somehow invite the malicious software to replicate ontheir system. Of course, most people have no idea it is there or what is happening. Some of the sneakiest and most harmful viruses actually masquerade as virus protection software, making them extremely hard to detect. Because of this, it’s crucial to be familiar with your particular virus protection program and know what it looks like and what the normal scripts and prompts are during operation. Viruses do some of the same things that spyware does; they just accomplish it differently. An active virus can steal personal information, generate ads or shut down your system, including the very virus protection programs that can fix the issue.
Take Steps For Protection
Like anything, the best way to protect against viruses is to be educated. Become familiar with what malicious software may look like. If you get an email or are asked todownload a file that you don’t recognize or looks suspicious, do your homework. Research virus protection, spyware, malware and firewall programs and use them to their fullest capacity. Set the software to update and scan automatically to make sure that the system is constantly monitored. In addition, regularly check on the databases published by various virus protection services; many will provide lists of symptoms and risks, as well as the standard way the file gains access for no cost to the public.
