History of Mobile Computing

Friday, July 16th, 2010

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. But, one thing is for sure, if you provide your computer with the proper protection, the detection and removal of these menaces would be no sweat. To aid you on this goal, it is important for you to be able to identify the types of antivirus software and how you can maximize its function.

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.

After knowing such details, it is up to you to choose the proper gadgets that you would need to protect or supplement the protection for your computer. It is hoped that the information you get from this article can help you decide which antivirus firewall software program to use for your computer..
