Shareware is the online access platform where you can get to try different software for free and then buy the one that best suits you. You do not need to walk to a store, buy boxed software, then get it home, try it on your computer and find that it is incompatible! Imagine the degree of dissatisfaction! Worst, most stores won’t even take it back if the only problem that you have is incompatibility. You are supposed to know that before you buy the software.

Not many people avail of the facilities that shareware offers, but frankly speaking it is one of the best options available for those who require constant upgrades and latest versions of their favorite programs. It has its niche follower base, but the truth is most people are not aware of its many advantages. Why is shareware better than commercial software purchase? Let’s see:

It is cheap. A package of spreadsheet, word processor, and database can cost you anywhere between $15 to maximum $100 in shareware while in commercial shops the whole package will cost you upwards of $200 and the Microsoft Office suite would cost you almost the same.

It can be purchased easily. Once you are at the appropriate shareware site, you can download the version that you need for free and test it easily on your computer. If you decide to buy it just use your credit card and buy it online immediately.

It is latest. The software versions available through shareware are latest. If in the commercial shops you are getting version 3.0, then in shareware you will get version 5.0 already available for testing and download.

It can be tried. You can try shareware software before actually letting go off your moolah! This in my opinion is the best advantage of shareware. No commercial shop will take back your opened box of software for the reason that it is not compatible. There is no knowing either before you try a certain software, whether it is compatible with your operating system or not.

Shareware is available online. Search for the software that your are looking for in Yahoo or Google and the results will take you to one Shareware website or the other. You will also get shareware site links in different online forums on software usability and functioning. Many authors of software and independent programmers provide shareware links in their individual websites as well.

Firewalls are network systems that block out unknown programs and internet processes from entering the system that is protected. It prevents any unknown user or program from accessing the system and therefore is not like Antivirus software. Antivirus software detects and removes programs that are infecting the system while the firewall only blocks anything from accessing the system that is being protected.

Firewall software is the first line of defense you have for your computer against viruses and users. It blocks out potential hackers and prevents them from accessing and retrieving any information from your PC. Identity theft is a very common problem nowadays and important information can get stolen from your system if you do not have the right protection. A firewall filters out information that is coming into your home network and only allows known users or programs to get through it. This is what an inbound firewall does.

If a hacker does manage to get past your firewall, you can get firewall software that prevents that hacker from taking information out of your network system. This is an outbound firewall and is your last line of defense against hackers.

Although, security software developers are now starting to come out with antivirus firewall software which combines the benefits of antivirus and firewall software together. It protects you from unknown users or programs as well as detects and removes programs that are slowing down and negatively affecting your computer. Antivirus firewall software is what we the recommend for security protection software.

The fascinating world of mobile computing has only been around since the 1990s. Since then, devices that have been developed for mobile computing have taken over the wireless industry. This new type of communication is a very powerful tool for both businesses and personal use. Mobile computing is defined as the ability to use technology that is not physically connected to any static network. This actually used to mean radio transmitters that operated on a stable base, usually with the help of large antennas. 2 way radios used by police officers were also considered mobile technology but now, it means people can connect wirelessly to the internet or to a private network almost anywhere. As long as a person has one of the devices capable of wirelessly accessing the internet, they are participating in mobile computing. Chances are, you have done it with a laptop computer or a personal digital assistant or PDA.

These days, most laptops and personal digital assistants all have wireless cards or Bluetooth interfaces built into them for convenient mobile internet access. Mobile solutions are right under everyone’s nose these days, and connectivity has never been easier. Other common tools for mobile computing include devices like global positioning systems and smart phones like the Cingular Blackberry. Tons of PDA software development has been going on in the past five years simply because companies have been trying hard to make PDA technology more available to the general public. These days, software companies almost make more software for PDAs and smart phones than for actual desktops.

Pocket PCs are another way to conveniently access the internet on the fly. Everyone has probably heard of the Palm Pilot. While they were the pioneers of the pocket pc, many other companies such as Dell, HP, and Toshiba have all delved into the market. Pocket PC software has also become much easier to use. Most Palms use the familiar Windows interface, allowing the general public to access the internet via the usual Internet Explorer or other ISPs. Also, people can easily download useful software, including games, Media editing tools, organization tools, and even electronic books.

Computer viruses are collectively referred to as malware or malicious ware. The set includes Trojan horses, spyware, adware, boot viruses, program viruses, rootkits and many more. Each varies in the places that it targets and the extent of damage it can cause. The process of removing and recovering from attacks of these viruses also differ.

You can set automatic scanning at the date and time that you wish to. This allows detection and elimination of the presence of viruses in unwanted disk, drives, files and folders.

Another type is the memory resident disk scanner. It is placed and allowed to run in the background. This pro-actively helps you to prevent entry of viruses as it scans websites, programs, files that you have recently visited or opened. It acts like a sweeper tracking your recent and current activities and making sure that they are safe and virus-free.

Behavior-based detection disk scanner is the third type of antivirus software. As the name suggests, it detects unusual behaviors and occurrences in your computer. This bars viruses from hiding other viruses and hard drives from being illegally reformatted.

The fourth type would be the start-up scanners. They are automatically run by the computer when it starts to boot. It scans disk boot sectors and critical system files. This type of antivirus software aims to scan and clean off the computer with viruses before the computer boots up.

The last type of anti-virus software is the inoculation disk scanner. This detects the changes and distortions that the viruses do to your computer files, folders, programs and system applications. It constantly checks for unwanted obliteration of any part of your computer.

The first thing to do for proper maintenance is to dust your machine from time to time. Dust is a problem because in many computer’s it will get inside on the components and block the vents. This is not good for your machine. Get a can of compressed air and use it to dust out your computer. This is best done when the computer is not plugged in and is detached from the battery.

Heat is the biggest killer of most hardware. Dusting your computer will help it cool off more efficiently and stay cooler. Take extra precautions to make sure you keep the computer cool. For a laptop be sure to get a cooler pad if the computer runs a bit hot. With your desktop don’t make the huge mistake of pushing your computer against the wall completely. This blocks the vents and adds extra heat.

Be sure that you shut down your computer properly. While you might think this is just a software issue, it’s actually related to hardware. When the computer is suddenly shut off, the internal components can have problems. Always do your best to go through a normal shut down.

Transport your machine carefully. If you are taking your computer from place to place, especially a laptop, get a bag that protects and fits the computer so there is limited shaking which can impact hardware performance especially a hard drive.

Always make sure you are plugged into a power strip. This is the best thing you can do to maintain your hardware long term. One power surge can ruin your computer completely.
