Config. Sys commands

CONFIG.SYS is a text file containing Disk Operating System command that tells the operating system how the computer is initially set up. CONFIG.SYS commands specify memory device driver and programs that control hardware devices; enable or disable system features; and set limits on system resources. CONFIG.SYS loads at startup before the autoexec.bat (automatic execute.batch program) file. Because CONFIG.SYS is a text file, it is editable in any text-editing program. The following are common commands in a CONFIG.SYS file:

· FILES=: This command tells the operating system how many files can be open at a time. By default, the setting is eight but most change it to between 20 and 40.

· BUFFERS=: The buffer are 528-byte areas in the RAM used for reading and writing to the hard drive. By default, the setting is 15. If you increase the buffer value ([´vælju:] - значение), reading and writing to the hard drive is faster. If it is too low, reading and writing to the hard drive is slower and may cause ((to) cause [kɔ:z] – вызывать, причинять) problems when the computer needs to execute tasks that require a lot of memory. It is common to set the buffers between 20 or 30.

· DEVICE=: This command loads drivers, commonly for the mouse and CD-ROM drive. Usually a command is automatically added to CONFIG.SYS when a device driver is installed.

· SHELL=: This command tells DOS where to look for its command interpreter, or COMMAND.COM file, and how much memory to set aside for DOS to use to execute commands.

· LASTDRIVE=: This command tells DOS the last drive letter that has been assigned.

Beginning with Windows 95, the commands in CONFIG.SYS are performed by the IO.SYS (input/output system configuration) file instead. Because older hardware devices need the CONFIG.SYS file, a blank CONFIG.SYS is still installed on computers that use Windows 95/98.

Any changes made to the CONFIG.SYS file may cause your operating system to fail when you boot it up. It is recommended not to change or add commands unless you are given explicit instructions about what command to add and how to type it.

Ex.6 Agree or disagree:

1. CONFIG.SYS is a text file containing Disk Operating System command that tells the operating system how the computer is initially installed.

2. CONFIG.SYS commands specify memory device driver and programs that control software devices.

3. CONFIG.SYS commands do not set limits on system resources.

4. If you increase the buffer value, reading and writing to the hard drive is slower.

5. DEVICE command boots drivers, commonly for the mouse and CD-ROM drive.

6. SHELL command tells DOS where to search for its command interpreter.

7. You can change or add commands without any particular instructions about what command to add and how to type it.
