Time sharing: Time sharing operating system was developed when computer systems were very expensive and shared by multiuser at the same time. This operating system enables the multi-users to share the particular system resources at the same time. In this technique, each and every task of the user is given specific time and the system restricts the execution of each task or job to only one interval at a time which assist the system to perform all the tasks smoothly without being interrupted. This operating system uses CPU scheduling and multiprogramming technology to offer each user small portion of time to perform their operation. Multitasking : As the name implies the term multitasking means several task is being processed at the same time. This technique contains common processing resources like a CPU and this resource is shared by each task or process. Practically, it is very difficult for a computer with single CPU to process more than one task at the same time this is when multitasking operating system becomes handy. It uses scheduling techniques that decide which task should be a running task and when the other tasks in queue should be performed. This operating system performs these operations with the help of a signal or interrupter which indicates CPU to keep the current task aside and save the present status in the buffer and return to another task.

Program Plan Intro

Time sharing:

Time sharing operating system was developed when computer systems were very expensive and shared by multiuser at the same time.

This operating system enables the multi-users to share the particular system resources at the same time.

In this technique, each and every task of the user is given specific time and the system restricts the execution of each task or job to only one interval at a time which assist the system to perform all the tasks smoothly without being interrupted.

This operating system uses CPU scheduling and multiprogramming technology to offer each user small portion of time to perform their operation.

Multitasking:

As the name implies the term multitasking means several task is being processed at the same time. This technique contains common processing resources like a CPU and this resource is shared by each task or process. Practically, it is very difficult for a computer with single CPU to process more than one task at the same time this is when multitasking operating system becomes handy.

It uses scheduling techniques that decide which task should be a running task and when the other tasks in queue should be performed.

This operating system performs these operations with the help of a signal or interrupter which indicates CPU to keep the current task aside and save the present status in the buffer and return to another task.

Assume that a string of name & surname is saved in S. The alphabetical characters in S can be in lowercase and/or uppercase letters. Name and surname are assumed to be separated by a space character and the string ends with a full stop "." character. Write an assembly language program that will copy the name to NAME in lowercase and the surname to SNAME in uppercase letters. Assume that name and/or surname cannot exceed 20 characters. The program should be general and work with every possible string with name & surname. However, you can consider the data segment definition given below in your program. .DATA S DB 'Mahmoud Obaid." NAME DB 20 DUP(?) SNAME DB 20 DUP(?) Hint: Uppercase characters are ordered between 'A' (41H) and 'Z' (5AH) and lowercase characters are ordered between 'a' (61H) and 'z' (7AH) in the in the ASCII Code table. For lowercase letters, bit 5 (d5) of the ASCII code is 1 where for uppercase letters it is 0. For example, Letter 'h' Binary ASCII 01101000 68H 'H'…
