[U115]Use Of Personal Computer

by Marco Maseko, Mar

With the onslaught of computer hackers, scammers, and viruses that are prevalent around the Internet, it is important to know how and why you should install a firewall. Defense from malicious data harming your computer is provided by a firewall. With one, you can avoid dangerous attacks that can wipe out your data or steal personal information.

Determine the type of firewall required by your computer as there are a wide variety available. Chances are that your firewall is already set up and ready to be used if you have a computer that came installed with the Microsoft XP or Vista operating system. You must check that it is turned on and working properly.

If you have one of the earlier operating systems, you will need to purchase your own software. Even with Microsoft XP, you may still want to purchase separate firewall software since the XP version doesn't get great reviews.

There are many products available, including as the most popular - Norton, AVG, and McAfee and you can either visit a store that sells computer software or download a firewall product through the Internet. Prices vary depending on sophistication of the software, but there are also plenty of low cost versions available, even from the big name companies.

You need to take a few things into consideration prior to installing your firewall. The program must not stop you using the functions that you need, such as file and printing sharing. This is normally done during installation but can also be done later by using the documentation provided to change the settings.

Firewalls can limit access to certain parts of the Internet. If you use a local area network or a router this may happen, so you should be aware how you connect. Secured networks are particularly difficult to access when you have a firewall installed. If you work from home or connect to a company computer, you need to coordinate with the IT department in your company before installing a firewall since they may have specific instructions concerning how to configure its settings so you are still able to connect to them.

Don't be surprised but buying a laptop can be even harder than buying a desktop computer. In fact, buying a computer is very straightforward. Laptops, however, are very personal stuff because it's something that you will carry around with you and sometimes act as more than just a computer for you to work on. They become a companion! That's why finding and selecting the right laptop can be very tricky.

Hard core computer gamers or people who will use their laptops for designing or video production may need more help than just reading about buying laptops. For conventional laptop users, here's something for you to digest.

The price for laptops varies drastically from brand to brand. Some laptops can cost $500 while some laptops can cost you $6,000. Some entry-level (meaning basic laptops) can be bought for between $600 and $900. If you grab a laptop off eBay or other rebate or drop shipping websites, you might get a mid-range laptop for far less than that.

Even for basic laptop users, the description and specifications for the laptop is very, very important. If you're not sure, check around and ask your friends for advice on how to buy a good laptop for the lowest price possible. You should be getting a laptop that comes with AT LEAST 512 megabytes of memory. The size of the memory ensures that your laptop can run multiple programs smoothly. As for hard drive, invest in as big a hard drive for your laptop as you can afford. Another thing that you may have to look out before you invest in the laptop is to find out how many USB ports that the laptop has. Most laptops come with at least 2 USB ports, the more the better. If you use a camera or thumb drive (disk key), this is where you insert the cable – the USB ports. You don't want to have to remove the USB cable for your printer and mouse every time you try to save pictures from your camera to your laptop! Some laptops come with slots for camera memory cards, for instance, your compact flash cards.

If you're keen on getting a Windows based laptop, the security of your laptop should be at the top of your priority lists. Windows SP2 XP should be ideal because it comes with antispam, antispyware, antipopups and antivirus programs. Some laptop retailers may offer you cheap or free programs that you can install into the laptop as a second layer protection to your laptop.

Other factors to take into account when shopping for laptops are the screen size, the life of the battery, the processor of the laptop, screen and keyboard, wi-fi networking, size and weight of the laptop.
