There are three distinct disadvantages to a laptop, however:
A laptop tends to be substantially more expensive than a comparable desktop model;
The largest monitor size available on any laptop today is about 17» (most computer monitors today are 19»);
(3) Laptop computers are easily stolen, and are popular with thieves.
Storage Media
Storage media is the most important element of your I.T. system, for this is where all your vital information – text files, spreadsheets, graphics, etc. – will reside. You’ll probably be keeping some of it on your computer’s hard drive, but it’s a very good idea to make sure that anything and everything you work on is backed up in a second and preferably third location.
Today, the best – and most widely used media – are rewritable CDs and DVDs. The media itself is relatively inexpensive, and most new computers are equipped with either a CD or DVD writer. Even if your PC lacks this accessory, external (plug-in) DVD writers can be obtained for as little as $50 new. The media itself is also inexpensive. Rewritable DVDs cost about $1.50 each in packs of 15, and offer a whopping 4.7 gigabytes of data storage. Compare this to the old 3.5» floppy disks commonly used ten years ago. These generally cost about $1 each and only furnished about 1 megabyte of data storage – roughly.00025% of a $1.50 DVD-RW.
That said, the 3.5» floppy is far from dead and gone. Many people still use them, and there’s a lot of information on them. Therefore, if your computer has no floppy disk drive, you’ll want to get an external drive, which can be purchased at any department or office supply store for about $30.
One other popular type of storage media from the past that’s still fairly common is the zip disk. If you’ve never seen one of these, they look like a 3.5» floppy on steroids, and are usually gray. Depending on the type, they hold either 100 MB or 250 MB of data. Again, these drives are easy to find and are available for under $100. (Note:
