MS-DOS

Henry rifle.

The MSBACKUP program in DOS receives its settings from the setup file. This setup file features a .set extension and is created after you make file selections and configure backup settings.

While most people today would probably think MS-DOS is something really complicated and hard to use, it is based upon simple concepts, and day to day use is extremely simple, once the initial system is set up. To launch a program, all you need to do is type its name. The program will then launch. Depending on the program, it may have all of the other features you'd expect to find in a more modern GUI. The hardest aspect of MS-DOS is probably memory management, but this is not something a typical user needs to fiddle with too much.

An operating system provides an interface between the hardware and the user. It allows us to use computers without having to know how to program them.

MS-DOS and most clones do not include a web browser in their core utilities. There are a few web browsers available for MS-DOS, but setting up and installing a packet driver for a network card in DOS is only slightly less difficult than cutting off your arm with a toothpick. The web browsers available also don't render most modern web pages correctly, and the performance is abysmal.

it creats a backup point in the computer when the operating system is currepted or at time of destroy your computer.

1.) in preemptive scheduling we prempt the currently executing process,

in non preemptive scheduling we allow the current process to finish its CPU burst time...

2.) in preemptive scheduling the process is forcibly sent to waiting state when a process with higher priority comes to CPU,

in non preeemptive scheduling the process at running state can not be forced to leave the CPU until it completes........

it means the model number , which is mentioned on the name tag on the motor top or on the side , depending on where the manufacturer puts it.

No need for a batch file, the following commands will do it:

CD folder

FOR /F %i IN (files.txt) DO DEL %i /P /F /S

The CD command sets the current folder. All deletions will occur in the specified folder and its sub-folders.

The files.txt file must be a list of file names (wildcards permitted) with one file name per line. If this file does not reside in the current folder you must specify the fully-qualified path or the relative path (relative to the current folder).

The FOR loop essentially executes the DEL command for each file in files.txt. The DEL command line switches are:

/P (prompt for confirmation before deleting each file)

/F (force delete read-only files)

/S (recurse through sub-folders of the current folder).

To suppress prompting, remove /P but add /Q (quiet mode) to suppress prompting on global wildcards. For more help on this, enter DEL /? at the command prompt. For more help on the FOr command, type FOR /? at the command prompt.

If used in a command script (.cmd) or batch file (.bat), replace %i with %%i. The only real advantage of using a batch file (other than to save a bit of typing) is that you can also pass the root folder and the file containing your file list as parameters (identified by %1, %2, etc).

You can't technically open MS DOS in notepad, but you can make files that MS DOS can use in notepad. For instance, you can create SYS, INI, BAT and others in notepad to make the computer do something, but MS DOS it self is dead. DOS will never die because of what it stands for. "Disk Operating System" You need a disk to run anything. Your hard drive is nothing more than a bunch of high tech cds spinning your files around.

MS-DOS is only capable of single-tasking without the use of rather complex TSRs. It also supports only a single user, has no access controls, no memory protection, and by default can only address 640 KB of RAM.

Batch: Jobs with similar needs are batched together and run through the computer as a group, by an operator or automatic job sequencer. Performance is increased by attempting to keep CPU and I/O devices busy at all times through buffering, off-line operation, spooling, and multiprogramming.

Well,the basic input/output system (BIOS) on a computer is a simple yet important program on a personal computer (PC) that helps the computer properly boot and run an operating system (OS) during startup. BIOS drivers are typically used in reference to the program itself, and how the program runs and interacts with other devices on the computer. The BIOS drivers on a computer are saved on a small battery located on the motherboard and allow for the proper initialization and startup of a computer when powered on.

In computing, a device driver or software driver is a computer program allowing higher-level computer programs to interact with a hardware device.

i have a metal sleeve over each spark plug wire at the motor.....cant get the wire out to get to the plugs?? how do i get the wire off the plug??

The difference is that competing processes in an operating system compete for resources. Cooperating processes share resources, and some even work together to complete the same task.

"msg" command might help. It pops up a message box on the users PC. C:/> msg <user_name> "Hello" "msg" command might help. It pops up a message box on the users PC. C:/> msg <user_name> "Hello"

They both allow us to execute commands.

Type in the notepad window "COMMAND", save it as "whatever.bat" (remember to select all files) then click on whatever.bat

The librarian's command is "shh!" ( or be quiet)!!!!!!!

Windows 2000, XP, and Vista do not have a "DOS mode." To start Windows 95 and 98 in MS-DOS mode, press F8 when the splash screen appears. Then select "Start computer in MS-DOS mode" from the list.

echo 127.0.0.1 insertdomainnamehere>>C:\Windows\System32\drivers\etc\hosts

Make sure you run command prompt as an administrator and check that the hosts file (in this folder: C:\Windows\System32\drivers\etc) is not marked for read-only.

it reads only text - based commands ( CUI )

it allows only one user to run a same program as another user at a same time

Macintosh!

For windows, windows 95
