Chapter 4, Problem 3WE
Explanation of Solution
Real-time
- It is a multiprogramming system that aims at executing real time applications.
- This operating system immediately responds to the given input. The task in this system is completed within a specified period of time.
- This OS is a time-sharing system which is based on clock interrupts.
- This operating system execute the process by using priority.
- Once a high priority process arrives into the system, low priority process preempted to support the high priority process.
- There are two types in the real-time operating system:
- Soft real-time operating system:
- In this operating system, a process might not be performed in given limit. This type is able to cross the limit without damaging the given machine.
- Example for this type is multimedia transmission and reception.
- Hard real-time operating system:
- In this operating system, a process should be executes in given limit...
- Soft real-time operating system:
Explanation of Solution
Difference between real-time and non-real-time operating system:
The difference between the real-time and non-real-time operating system is given below:
| Real-time operating system | Non-real-time operating system |
| This operating system is deterministic. | This operating system is not deterministic. |
| It is time sensitive. | It is time insensitive. |
| It can’t use virtual memory. | It can use concept of virtual memory. |
| It is mostly used in the embedded application. | It is mostly used in the desktop and personal computer... |
Explanation of Solution
Three situations are needed for real-time operating system:
The three situations in the real-time operating system are ATM machine, aircrafts and medical equipment’s.
- Reasons for ATM machine using real-time operating system:
- People can quickly access their account.
- People can also withdrawal amount from the ATM machine at any time and within seconds.
- Reasons for aircrafts using real-time operating system:
- Aircrafts use real-time system for the passenger’s safety...

The assignment here is to write an app using a database named CIT321 with a collection named
students; we will provide a CSV file of the data. You need to use Vue.js to display 2 pages. You should
know that this assignment is similar, all too similar in fact, to the cars4sale2 example in the lecture notes
for Vue.js 2. You should study that program first. If you figure out cars4sale2, then program 6 will be
extremely straightforward. It is not my intent do drop a ton of new material here in the last few days of
class.
The database contains 51 documents. The first rows of the CSV file look like this:
