Cheap and Fast Software An Introduction to Shareware Visit any computer store today and you'll find what seems like miles and miles of software on sale. Certainly enticing buys, there are a few problems with buying software off the shelves. On the shelf, software - otherwise known as "commercial software" - can be expensive, and incompatible, and outdated when compared to what's available online. The commands in a program are pretty useless unless they have some data to act on so programmers either give the programs some data to work with (list of names or numbers for example) or they make the program generate it's own data. Sometimes, the data comes from an outside source like the Internet or the computer that the program runs on. You could make a batch file that loads up your favorite websites at once for example, or you could make a batch file that fills your desktop with the most important applications for the day. To do so only requires a little knowledge about the locations of these applications. Let's say that every day we need to load up the Yahoo web browser, Microsoft Word, and then the calculator that comes with Windows. Venturing off the beaten path with lessor-known brands is again, an adventure for those who have more experience with computers. Although those better-known brands may be a tad bit more expensive, the computer novice will appreciate the comfort in purchasing a computer from a business that has a long record of building quality products, and that has the funds available for fulfilling returns, trades, servicing, and warranties. So even though your co-worker may have emailed a funny video, it's no more safe to open than a video downloaded from a complete stranger. Be safe and scan each and every file you download from the Internet or receive through email regardless of where it came from. 4. Create a barrier between your computer and prying eyes. The easiest and cheapest method uses an Ethernet connection, which requires a series of network cards, a cable for each computer, and a router. The network card is similar to the old modems we used in the past to connect to the Internet, however in a home network, it's used to communicate with every computer that's connected to it.
