Types of Single User Operating System

It can classify into two parts:

1. Single Task Operating System

In this, only one user can perform a task at a time. This operating system specially designs for cordless phones and two-way messaging devices. Some functions, such as printing a document and downloading images and videos, are performed after the idea is provided.

Some examples of operating systems are MS-DOS, Palm OS, etc.

Advantages:

  • Use less memory space.
  • It is profitable.

Disadvantages:

  • It is capable of performing only one task at a time.
  • It is less optimized.

2. Multitasking Operating System

The multitasking operating system specially develops for one user, but that single user can simultaneously perform multiple tasks. Some examples include typing any text while browsing the Internet and downloading images while watching movies, etc.

Examples of operating systems: Windows, Linux, Mac O / S

Advantage :

  • A time saver.
  • High productivity in less time.
  • Less memory use for multitasking.

Disadvantages:

  • I need more space.
  • It has more complexity.

Features of Single User Operating System

  • It has no security.
  • It does not use MMU.
  • And also, it does not use a planning process for I / O.
  • Use less planning for users.
  • It only intends for single use.
  • It is not designed for multiple tasks at the same time.

Advantages of the Single User Operating System

It has several advantages, such as:

  1. It allows such an interface in which only one user works simultaneously, and another user cannot interrupt processing.
  2. Therefore, this operating system does not need to support the overhead of requests from multiple users.
  3. Multiple resources do not use in a single operating system, so they are less complex. For this reason, this operating system is only required for simple maintenance and debugging.
  4. Due to the lower overhead of sending requests per user, both hardware and software. Therefore, they are no longer likely to harm them.
  5. Due to the unique user interface, this operating system only allows tasks to run at a time. Therefore, the user concentrates on a single charge instead of multiple tasks.

Disadvantages of the Single User Operating System

There are some limitations of it. Describe each below:

  • And also, it cannot perform multiple tasks simultaneously, so the processor waits for execution until a job completes.
  • This system cannot optimize CPU, memory, and disk I / O to the optimum level due to high CPU sleep group demand.
  • He is slow.
  • It has a high response time.
  • And also, it uses high downtime.

Difference Between Single User Operating System and Multi User Operating System

single user operating system

It is a system in which only one user at a time can access the computer system. A multi-user operating system is a scheme that lets multiple users access a computer system at the same time.

The difference between a single-user and a multi-user operating system is detailed below:

CHARACTERISTICS  SINGLE-USER OPERATING SYSTEM  MULTI-USER OPERATING SYSTEM
Definition It is a scheme in which only one operator can access the processer system at a time. It is a scheme that lets more than one operator access a computer system at one time.
Super User  A superuser gets all the powers of maintaining the system and making changes to ensure the system runs smoothly. Superuser does not exist when it comes to a multi-user operating system as each entity controls its working.
 Complexity  It is humble. It is complex.
Performance  Only one task at one time gets achieved.   Schedules different tasks for presentation at any rate
Example  Windows, Apple Mac OS  UNIX, Linux, and also Mainframes

Conclusion

It is also known as the “single-task operating system,” specially designed for personal computers.

It allows only one user to access your personal computer at a time, but it can support multiple profiles at any given time. And also, it is used in official work and other environments as well. Therefore, this operating system is not required to support memory protection, fire protection, and system security.
