《建设工程委托监理合同（示范文本)》规定，实施监理工作过程中的额外工作是指（)。A．承包人的原因施工

There are two common types of disk drives: a hard disk drive (sometimes called a fixed disk drive) and a diskette drive (sometime called a floppy disk drive).(47)(Some models might not have a hard disk drive. ) With a hard disk, your computer can store large amounts of information (called files) in one convenient place. Using a hard disk, your computer can save and retrieve information much faster than with a diskette drive.(48).

Each disk drive has a letter assigned to it, so you can tell your computer where to find information.(49)If you have a hard disk drive, it is called drive C.

If your computer has a hard disk drive, drive C, then you can store your operating system and other programs on the hard disk.(50)If your programs and information files (data files) are well organized, then your computer can find and retrieve the information much faster. Check your operating system documentation for information about how to set a directory.

If your computer has no hard disk, then you must use the diskette drive to load your programs and to store your information. Your operating system and application program documentation have information about using disk disk drives and making program diskettes and data diskettes.

(46)

A. For example, if your computer has two diskette drives, one is called drive A, the other is called drive B.

B. The hard disk drive is built into your computer.

C. The key to using your hard disk effectively is the way you store your information.

D. The 5.25-inch diskette is thin and flexible.

E. The AAA computer comes with a diskette that uses 3.5-inch diskettes.

F. A diskette drive uses a removable diskette, which has less storage space than a hard disk.
