Question 1 Explanation: 
→ A real-time operating system (RTOS) is any operating system (OS) intended to serve real-time applications that process data as it comes in, typically without buffer delays.
→ Processing time requirements (including any OS delay) are measured in tenths of seconds or shorter increments of time.
→ A real time system is a time bound system which has well defined fixed time constraints
→ A multitasking operating system like Unix is poor at real-time tasks. The scheduler gives the highest priority to jobs with the lowest demand on the computer, so there is no way to ensure that a time-critical job will have access to enough resources.
Question 2
Remote computing system involves the use of time sharing systems and :
A
Real time processing
B
Batch processing
C
Multiprocessing
D
All of the above

Question 2 Explanation: 
→ Remote computing system involves the use of time sharing systems and Batch processing.
→ Batch processing in which an input device is located at a distance from the main installation and has access to a computer through a communication link.
Question 3
If you want to execute more than one program at a time, the systems software that are used must be capable of :
A
word processing
B
virtual memory
C
compiling
D
multitasking

Question 3 Explanation: 
→ Multitasking does not require parallel execution of multiple tasks at exactly the same time.
→ Multitasking allows more than one task to advance over a given period of time.
→ Even on multiprocessor computers, multitasking allows many more tasks to be run than there are CPUs.
Question 4
Remote Computing Service involves the use of time sharing and _______.
A
multi-processing
B
interactive processing
C
batch processing
D
real-time processing

Question 4 Explanation: 
Remote Computing Service involves the use of time sharing and batch processing.
Question 5
An example of a distributed OS is :
A
Amoeba
B
UNIX
C
MS-DOS
D
MULTICS

Question 5 Explanation: 
Amoeba is a distributed operating system developed by Andrew S. Tanenbaum and others at the Vrije Universiteit Amsterdam.
Question 6
In which of the following, ready to execute processes must be present in RAM ?
A
multiprocessing
B
multiprogramming
C
multitasking
D
in all of the above

Question 6 Explanation: 
Multiprocessing, multiprogramming and multitasking is ready to execute processes must be present in RAM.
