Hard disk drive is the mechanism that reads and writes data on a hard disk. Hard disk drive has many inflexible platters (discs) coated with magnetic material. Read/write heads can record computer data on these discs. A typical hard disk rotates at 3,600 revolutions per minute, and the read/write heads ride over the surface of the disk on a cushion of air 25 micron deep. Hard disk drives (HDDs) for PCs generally have seek times of about 12 milliseconds or less. Hard disk drives are sometimes called Winchester drives. Winchester is the name of one of the first popular hard disk drive technologies developed by IBM in 1973.

Under MS-DOS 3.20 you can create and access names for many different types of devices - just as if they are physical disk drives installed in your system. The devices you can access as disks are:
- internal floppy-disk drives
- external floppy-disk drives
- additional drive identifiers for floppy-disk drives, defined by DRIVER.SYS
- hard-disk drives of many different sizes
- RAM disks created in the computer’s memory
- directories that  have  been given logical  drive names using SUBST

Microprocessor is a silicon chip that contains a CPU. The terms microprocessor and CPU are used interchangeably. At the heart of all personal computers sits a microprocessor.
Microprocessors have basic characteristics:
Computational bandwidth: The number of bits processed in a single instruction.
Speed: Given in megahertz (MHz), the speed determines how many instructions per second the processor can execute.

Hard disks can be divided into one to four separate sections, called partitions. Partitions separate your hard disk into individual areas, and each partition may contain a different operating system.
To prepare your hard disk for the MS-DOS operating system, you must create a partition for MS-DOS, called a DOS partition. You can create a DOS partition on your hard disk by using a menudriven utility called fdisk. You must use fdisk if you want to do one of the following:
- Create a primary MS-DOS partition
- Create an extended DOS partition
- Change the active partition
- Delete a DOS partition
- Display partition information
- Review or modify the configuration of another hard disk on your computer

FILINK is a utility that moves data or program files between two Epson computers joined by a cable. Transferring files this way overcomes the difficulties of mismatched disk formats or conflicting operating systems.
All you need are cable connection between the RS-232C ports of the two machines and a FILINK program running on each. Epson’s FILINK is compatible with Epson equipment, but not with other machines and software you may use.

The names of your files are kept in a directory on each disk. The directory also contains information on the sizes of the files, and the dates they were created and updated.
If you want to know what files are on your disk, you can use the DIR command. This command tells MS-DOS to display all the files in a specific directory on a disk. For example, if your MS-DOS disks are in drive A and you use the DIR command, the directory display would look similar to this:
Volume in drive A is DOS 3-3
