Do I Really Need to Use Antivirus Software?
When you are choosing antivirus software, you may have narrowed it down to a few programs, but you aren’t sure which ones you should pick. If so, there are a few features of the antivirus programs that you should look at and compare to help with your antivirus decision.
One thing that may be helpful when picking between several antivirus software programs is looking for consumer websites. Typically these websites have already done the reviews of the antivirus software for you, and can show you how various components rate. The only problem with online antivirus comparisons is that the programs you are looking for may not be in their comparison, which leaves you back at square one.
Due to this, you may have to do your own comparison of the antivirus programs, so there are a few things you want to watch and check for with the antivirus programs. You likely will want to load up their websites and find the feature pages for that antivirus, and compare based on that.
Updates – Will the antivirus software do its own updates automatically? You need your software to be current at all times, as there are always new viruses being released on the Internet. If you cannot have it automatically update at least once a day, then you do not want that particular software.
Scanning Capabilities – Will the antivirus software scan everything you need it to? Can it scan incoming and out going email for viruses, scan files you are downloading, as well as websites you are browsing? If the antivirus program cannot do these, then you are going to want to look for another antivirus program.
Licenses – How many computers can you install the antivirus program on? With more households running more than one computer, this can be an important factor in deciding on a program. You want to make sure that any software you purchase can be installed on more than one machine, as it can get pricey to purchase multiple versions of any antivirus program.
Usage – Another big thing when looking at antivirus program is what you use your computer for. If you just do some browsing, email or games, you likely won’t be too at risk for viruses. But, you will still need an antivirus program of some sort, just maybe not as robust or powerful as other antivirus programs out there. If in the future you decide to change your Internet habits, you will want to re-evaluate if your antivirus is still able to handle your needs.
If you haven’t already gotten some sort of antivirus software, you need to take care of that right now! Antivirus software is not an option anymore; it is a requirement when you are on the internet. When you get a new computer, one of the very first things you should be doing is getting your antivirus software set up, even before you start checking email or anything else! You never know where a virus is hiding!
How To Select The Best Printer For Your Needs
There are a couple of things you need to first understand before you purchase a printer. They include;
1. Whether it is LaserJet or Inkjet.
Both LaserJet and Inkjet printers have advantages and disadvantages.
Inkjet printers are cheaper to buy than LaserJet printers. They also have very good quality print outs. However, the cost of maintaining an Inkjet printer is very high. Also, Inkjet printers make a lot of noise while printing and are slower than LaserJet printers.
LaserJet printers are expensive when buying but very cheap to maintain. Their print quality is very high and they make less noise when printing. They print faster than Inkjet printers.
2. All-In-One or Print-only.
The next thing you need to consider is whether you just want a print-only device or you need to scan copy fax and print.
Print-only printers are cheaper than All-In-One printers. However, they have limited functionality.
On the other hand, All-In-One printers have scanners, copiers and printers all put in one device. They are a little bit more expensive but very handy especially in an office setting. All-In-One printers also save space as they contain three different devices in one.
Some All-In-One printers have fax. When getting an All-In-One, always confirm if it has fax as not all of them have fax. In most cases All-In-Ones that have fax are more expensive.
3. Print Or Scan Quality.
Various aspects of print and scan qualities can be compared between different models. Print resolution is usually measured in dots per inch (DPI). The higher the number of dots per inch the better the printer.
Inexpensive inkjet models usually generate black-only prints at least as high as 600×600 DPI. Color models, meanwhile usually start as high as 4800×1200. Laser jets, meanwhile, typically produce
1200×1200 DPI or better black-only prints and 1200×600 or better color prints.
Scan quality is measured using both bit-rate and DPI measurements. If scanning is an important feature,
seek an all-in-one device that offers optical scan resolutions of at least 600×1200 DPI and at least a 24-
bit scan rate. Again, higher numbers are better (a scanner that boasts 36- or 48-bit technology will
produce even higher-quality scans).
Be sure to consider the differences between an inline scanner, in which 8.5-inch x 11-inch pages are
easily scanned by passing them through a sheet feeder, and a flat-bed scanner, in which odd-size
documents can be easily scanned just by placing them on the glass. In environments where multiplepage documents will frequently be scanned, ensure you select a model that boasts an automatic feed
tray.
4. Network Capabilities.
The days where parallel cables where used to connect printers to computers are long gone. In fact, most laptops nowadays do not even have parallel ports. Most printers nowadays are connected to computers via USB cables.
Many printers now boast integrated wireless LAN connectivity. Other models feature embedded network interface cards, making it possible to connect printers to a local area network via a
standard wired Ethernet cable, and thereby usable by multiple PCs simultaneously. Still others feature integrated Bluetooth support, which makes it possible for laptop users (among others) with Bluetooth functionality to print wirelessly without the requirement that a local area network even be present.
When reviewing a printer or multifunction device purchase, be sure to consider your organizations needs. If multiple users will need to access the printer or all-in-ones scanning functions, network-equipped models can eliminate the need to purchase multiple units or configure a single PC to host print services for other systems. If many users access the
local area network wirelessly, be sure to consider a printer model that also includes WLAN connectivity.
