Dealing with Digital Disease

Written by Sean Felker

A virus is a program that replicates itself. It cannot exist on its own so it attaches to another program, usually an executable one.

A worm is like a virus—it also replicates itself. However, it can stand on its own and does not need another program to run.

It usually infects your computer’s networking features, which includes its internet connection.

Spyware and adware go hand-in-hand. Spyware is a kind of program which gathers information, specifically browsing habits. It tracks down what kind of sites you visit, andrepparttar adware will generate ads that fit with your interest whichrepparttar 147775 spyware based on information it gathered inrepparttar 147776 first place.

Malware is malicious software. It’s any program that is useless, or worse, destructive.

In spite of all their differences, they have one thing in common: they are out to give you headaches by rendering your computer unusable

To protect your computer as much as possible from being infected, here are four dangerous activities that you should avoid, or at least minimize

Opening email attachments: Do not open any email attachments if they aren’t scanned by antivirus software. Worms can spread through email, so even a friend can unwittingly send you one by way of an attachment.

Internet File-sharing In file-sharing viarepparttar 147778 internet, your computer is exposed and open to others it is communicating with. If other computers’ files can be transferred to yours,repparttar 147779 same thing can be said about a virus, ifrepparttar 147780 others are infected.

Downloading free software of questionable origins. Free software is free for a reason.

If you bothered to readrepparttar 147781 End User License Agreement (EULA) of a software you are installing—which you probably didn’t—you most likely will come upon a short and tiny clause saying that if you agree torepparttar 147782 terms, you are allowing advertisements to pop up on your screen, or other software to be installed in your system.

Laptops arerepparttar natural evolution inrepparttar 147745 ever changing world ofrepparttar 147746 computer. The improvement of technology has allowedrepparttar 147747 computer to shrink from being as big as a house, torepparttar 147748 size of book.

Their compactness, and portability makesrepparttar 147749 laptop particularly useful torepparttar 147750 professional,repparttar 147751 person onrepparttar 147752 go, andrepparttar 147753 student. However, laptops can get rather expensive so you should take care to choose a laptop withrepparttar 147754 right amount of features, but not so many that they needlessly inflaterepparttar 147755 price.

Here are 9 basic features that you should consider before you purchase your next laptop:

1. Weight and Size: When it comes to weight and size, you should consider thatrepparttar 147756 bigger a laptop is,repparttar 147757 heavier it is. A small enough size should be chosen, but not so small that it's uncomfortable. The smallerrepparttar 147758 laptop,repparttar 147759 more awkward it will be to type on that tiny keyboard.

2. Display: The display, or screen is directly tied in torepparttar 147760 size ofrepparttar 147761 laptop. You should chooserepparttar 147762 biggest display possible. Also, a decision has to be made between Active, and Passive Matrix.

Active Matrix is more expensive, but is recommended since pictures come out sharper and moving images play out smoother. Passive Matrix is cheaper, butrepparttar 147763 picture quality is not as good.

3. Batteries: There are 3 main types of Batteries. They are Li, NiMH, NiCad. What those letters stand for is not important. All you need to know is to always choose Li since they are higher quality, and provide a longer life. However, they are slightly more expensive. If one is strapped for money, then NiMH is acceptable. They're slightly cheaper, but must be recharged every hour or so. Under no circumstances should NiCad be chosen. They're extremely low quality, and have no staying power.

4. Hard-Drive: Most laptops start with at least 4.3 gigabytes, or GB, of hard drive space. However, you can get more hard-drive space if you think you’ll need it.

5. CD-DVD Drive: To be honest, a laptop doesn’t really need either one. But at least one should be added since most software comes in CD form nowadays. If you choose a DVD-ROM drive, then a CD-ROM drive won't be needed since a DVD-ROM drive can read CD-ROMs.
