computer with PC or MS DOS and a hard disk. If your computer does not have a hard disk, then this is the wrong manual for you; DOS is very easy only if you. Microsoft® MS-DOS®. Reference. HP Series / Computers. HP Part Number Flin- HEWLETT. ~~. PACKARD. Hewlett-Packard. DISK OPERATING SYSTEM (DOS) is a system software, which is closely As DOS was written by Microsoft Corporation, usually it is called MS-DOS. IBM has.

Memory Management 1. Mention that to run a second job, the user must close or pause the first file before opening the second.

Point out that the Memory Manager uses a first-fit memory allocation scheme in early DOS versions because it is the most efficient strategy in a single-user environment. Point out that Version 1. Discuss the two factors that determine the amount of memory each application program actually owns. Using examples such as those provided on page , explain that two programs cannot be run at the same time in MS-DOS. Explain the task performed by a Memory Manager when a program that is already running needs more memory.

Be sure to mention that the shrinking and expanding of memory allocation during execution can be done only from programs written in either assembly language or C. Discuss briefly the memory block allocation schemes used in different versions of MS- DOS, including first-fit, best-fit, and last-fit.

Use Tables Discuss the consequences of a broken list. Note the characteristics of well-designed and poorly designed programs in terms of memory block allocation. Explain how two contiguous free memory blocks are immediately merged into one block and linked to a list.

Processor Management 1. Explain that the Processor Manager has the relatively simple task of allocating the processor to the resident job when it is ready for execution. Process Management 1.

Remind students that MS-DOS was designed for a single-user, single-task environment, and therefore does not support reentrant code, which is the basis for multitasking. Explain that there is no interleaving in MS-DOS systems, so there is no need for sophisticated algorithms or policies to determine which job will run next or for how long.

Multitasking is an illusion handled by the synchronization of tasks using interrupt handlers. It allows a parent Tip program to go to sleep while the child runs along on its own.

These programs look and feel like multitasking operations because they retain their memory area and run executable programs, but they are not both in the running state at the same time. The synchronization between the parent and child tasks is handled through interrupt handlers.

List three types of interrupts: internal hardware interrupts, external hardware interrupts, and software interrupts. Explain how these are created and whether or not they can be modified. Provide examples of these interrupt handlers. Discuss the tasks performed by the CPU when it encounters an interrupt. Point out that the CPU uses the eight-bit number placed on the system bus by the interrupting device to get the address of the appropriate interrupt handler.

Device Management 1.

Discuss various features such as the following: it handles requests on a first-come, first-served basis; it does not support reordering requests; etc. Quick Quiz 1 1.

Which of the following contains the routines needed to interface with disk drives? BIOS b. DOS Kernel c.

COM d. Choose all that apply. Two programs cannot be run at the same time. The amount of memory each application program actually owns does not depend on the size of the TPA. Answer: a and c 3. Answer: True File Management 1. Point out that although sequential files can have either variable-length or fixed-length records, direct and indexed sequential files can only have fixed-length records.

Filename Conventions 1. Make sure students clearly understand the difference between the relative name and absolute name of a file, and when each is used. Be sure to point out that DOS is not case sensitive, so filenames and commands can be entered in uppercase, lowercase, or a combination of both.

Managing Files 1. Point out that the earliest versions of MS-DOS kept every file in a single directory, which makes the file retrieval process slow and cumbersome. Microsoft implemented a hierarchical directory structure in Version 2.

Discuss the concepts of formatting into byte sectors, cylinders, and clusters in the MS-DOS operating system. Outline the information contained in each of these areas. Use the examples shown in Figure BAT file.

Understanding Operating Systems, Fifth Edition 14 -8 6. The FAT links every sector for each file. Use the example shown in Figure Discuss several other features of file management, such as how MS-DOS looks at data in a disk file as a continuous string of bytes, supports noncontiguous file storage, and dynamically allocates disk space to a file.

Point out that security features are not built into MS-DOS, and that data is kept secure by keeping the computer physically locked up or by removing the disks and keeping them in a safe place. More precisely, the information propagates not only in 1 direction usually the time for 1D systems but in 2 or more directions. If you are familiar to view systems as transfer functions, here are simple examples to help you understand the differences between a 2D and a 1D system: If you are familiar with the state-space approach: Why study nD systems?

Well, firstly because it is mathematically challenging and don't we all love challenges!?

Note that nD systems are part of the class of infinite dimensional systems. This in turns implies several difficulties whilst dealing with nD systems the first one is that there are an infinite number of 'poles' to the system from the example given below, all the points such that. The second one is that the initial conditions are given by an infinite number of points or functions in the continuous case which in turn creates several problems when dealing with stability.

But that's not all, if you like surprises, then nD systems are for you as well. Goodman in a famous paper published in showed that contrary to the 1D case, the numerator can influence the stability of the system because of the existence of what he called nonessential singularity of the second kind math stuff…. And finally, the underlying ring functions of 2 or more variables does not have a division algorithm and a lot of usual concept for 1D systems stems from this fact.

Specific solutions are therefore needed for nD systems. The second point we would like to make is more about the physics.

Many physical processes have a clear nD structures and it makes sense to model and study them as part of the multidimensional framework.

Usual applications found in the literature are: Repetitive systems such as metal rolling or long-wall coal cutting Iterative learning control fishing everyday and getting better everyday Image processing and the use of nD digital filters.MOVE:- It is an external command which is used to move or transfer files from one location to another.

REM:- It is used to mark on command for not execution.
