| Windows 98 and Windows 2000 both support DOS commands in order to | address compatibility issues related with older applications |
| DOS is a collection of programs and commands used to | control the overall computer operation in a disk-based system. |
| three distinct sections that make up the disk operating system (DOS) | Boot files, File management files, Utility files |
| Utility files | Enables the user to manage system resources, troubleshoot the system, and configure the system settings |
| File management files | Enables the system to manage the data that it holds. |
| Boot files | Used during the boot process (that is, start-up). |
| DOS programs usually work in the | background |
| the disk operating system is responsible for | finding and organizing data and applications on the disk. |
| All generations of Windows to date support DOS commands for | backward compatibility with older applications. |
| DOS is a command | line operating system |
| DOS can only run | one program at a time |
| DOS can only run | small programs and has memory limitations |
| DOS is an essential tool for IT professionals and is used | extensively for troubleshooting |
| The way that programs and data are stored on a disk is set up much like a | filing cabinet |
| In DOS, they are called files and are grouped together in | directories |
| Directories can be nested inside other | directories |
| A simple block of logically related data that is given a single name and treated as a single unit | file |
| File Allocation Table (FAT) | A record of the location of every directory, subdirectory, and file found on a disk. |
| In DOS, filenames can be up to | eight characters with an extension of three characters |
| Separated from the main portion of the filename by a period that identifies what type of file it is | file extension |
| a set of parameters that describe a file | files attributes |
| conceal important files and keep them from being seen and possibly tampered with by unauthorized users | Hidden files |
| Hiding a file makes it | invisible to a standard DOS directory listing |
| command to see a hidden file | C:\>dir /ah |
| The main directory | root directory |
| In MS-DOS, a graphical representation of the disk drive's directory organization is called a | directory tree |
| The first hard drive in most computer systems is labeled | C |
| The root of the C drive is represented by | C:\ |
| format for specifying the path to a file | C:\directory name\subdirectory name\filename |
| back slash | \ |
