486: An older CPU that was constructed at the beginning of the Windows 95 revolution. This CPU works great if you are running MS-DOS or Windows 3.1. In general, this is one of the things that should be considered when purchasing a computer.
Hard Disk Drive (HDD): This is the internal magnetic storage device housed inside the computer case. These come in a variety of sizes, measured in how many bits of information they can contain. A bit of information equals either zero (0) or one (1). To a computer, this is equivalent to turning a light switch off (0) or on (1). Computers operate on bits in groups of 8, called a byte. Every byte contains 8 bits. Bits and bytes can be stored magnetically on material that resembles cassette or 8-track recording tape. The magnetic material stores information as sequences of the digits "0" and "1" (hence the name digital storage). Since it takes many bytes to store such things as letters, words, and sentences, the amount of information that a Hard Drive can store is measured in multiples of 1000-bytes, 1,000,000 bytes, or 1,000,000,000 bytes. Terms such as kilobyte (1000 bytes or 1KB), megabyte (1,000,000 bytes or 1MB), and gigabyte (1,000,000,000 bytes or 1GB) have evolved to represent these storage capacities. When you purchase a computer, get as large a Hard Drive as you can afford. The standard in 1998 was between 4GB and 8GB. The Hard Disk Drive is often referred to as the "C:" drive
