Integrated Office Systems.
Word processing, data processing, image processing, voice processing, photo type settings,
micro graphics, Fasci mail, Tele Text, LAN, PABX, etc. are part of an integrated office system.
Integrated work station is the major component of integrated office.
Integrated work station performs all kinds of functions like Word processing, data processing,
image processing, voice processing, electronic mail, photo type settings, micro graphics, Fasci
mail, Tele Text, LAN, PABX etc. The communication net works act as the glue that binds the
components of the integreated office systems.
Disk Oerating System (DOS)
The operating system(OS) is the first program that must be loaded into the memory of your PC
before you can use it for any application. You can start your computer wuth DOS or some other
operating system such as Windows.
Internal and External DOS commands
There are two types of DOS commands. Internal and External. The Internal commands are
those commands that are automatically loaded in the memory of your PC when DOS is liaded.
They are built into the operating system as part of a file called CMMAND COM. These
commands can be used without the need of any DOS file or diskette. The internal commands
are simple and are used for common tasks such as copying, renaming or erasing files,
displaying a list of files in a diskette, creating and changing directories, changing the current
date in your PC etc.
Eg:
CLS COPY DEL DATE TIME PATH DIR PAUSE CD RD MD VOL VER
On the other hand, the, the external commands are used for relatively complex jobs such as
copying the entire diskette, formatting a diskette, comparing or joining files, sorting text etc.
External commands are executable program files in the disk storage. To execute an external
DOS command the corresponding program file must be available in the computer. These files
usually have. COM OR EXE as the filename extension.
Eg:
ATTRIB LABEL LABEL BACKUP CHKDSK MORE FIND SYS FORMAT PRINT
TREE DELTREE charecters in lengh
Files
A file is simply a collection of information that you store on the secondary storage. Each file
must have a unique name. However two files can share the same name provided that they are
ondifferent disks, or in different directories.
The file name has two parts: the filename itsrlf and an extention. File name is the base
name of the file itself. In DOS, this part of the file name must be between one and eight
charecters in length. File Extension of the file, which is optional and hence can be from zero to
three characters.
Eg:STUDENT DOC
STUDENT is the file name and DOC is the file name extension

Copying a File
The COPY Command is used with the following syntax.
COPY<Source filename> <Destination filename>
