Multi User Operating System: Examples, Types, Advantages, & Features!!

-

Multi user operating system is a special operating system that allows to the multiple users on different computers or nodes to get access a single system along with one operating system. So, now here we will explain about what is multi use operating system and its examples, types, working, and working; involving with various advantages and disadvantages of multi user operating system without getting any hassle.

What is Multi User Operating System

Definition – A multi user operating system allows to permission of multiple users for accessing the single machine at a time. All different users can access that system running operating system with the help of several terminals, which are connected in networking form. Here, we will explain of multi user OS in detail.

Multi-User-Operating-System 

Main objective of designing of Multi user OS is used to time sharing and batch processing on mainframe system. Now these days, this multi user operating system is used in the large organization, government sector, educational system such as large scale university, and mostly used in the servers side like as Ubunto Server or Windows Server. These servers grant the permission of multiple users to accessing the operating system, kernel, and hardware simultaneously.

Component of Multi User Operating System

There are four types are software components of multi user OS. Below explain each one.

Kernel

Multi user operating system uses the Kernel component in low level, and it is written in the low level language. This component is embedded in the main memory of computer system, and it can interface directly with H/W of system.

Device Handler

Main goal of device handler is to provide the all requests on entire device request queue pool. Device handler is designed individually for every input and output devices. Device handler works as continuous cycle mode, and firstly it discards the Input/output request block from queue side.

Spooler

Spooler stands for “Simultaneous Peripheral Output On Line”. Spooler executes the all computing process, and it provides the output at same time. Several output devices use the spooling, for example printer.

User Interface 

User interface is the communication medium in between the users and all functions of software an hardware. Main objective of using user interface is to create simple environment for all users for using the computer system.

Types of Multi User Operating System

There are three different types of multi user OS with classification, and here we will describe each one:

Distributed Systems

In this, entire system is distributed in the network form, and every terminal is connected with each other with high speed buses or telephone line. In the distributed system, any user can access of system’s resources from anyone terminal of distributed system.

Time-Sliced Systems

In this type of system, small time duration is allotted to every task. CPU time is divided into small time slices, and one time slice is assigned to each user, and this time slices are very short duration. They use the mainframe system at concurrently.

Multiprocessor System

This system involves the multiple processors, and it helps to improve the performance of entire system. If, in this system one processor gets fails then other processor has to responsible for completing of its assigned task.

How to Work Multi User Operating System

The multi user system contains the single master system. This master system can be accessed by all users anywhere and anytime on network, and they can open own local view of system. This local view is also known as “working model”.

All users can make any updating, deletion, and create new file on their working model at local area, but this working model will not show to another users until they save own working model to master system.

Features and Characteristics of Multi User Operating System

There are some features and uses of multi user operating system.

Multi Tasking – Multi user O/S is capable to perform couple of tasks at concurrently, and multiple programs can be run on this operating system at a same time.

Resource Sharing – In the multi user operating system, several peripheral can be shared such as printers, fax m/c, plotters, and hard drives etc. Due to this feature, users can share own documents. In this system, tiny time slice of CPU time is allotted to all users.

Background Processing – In which, if given instructions are not processed, and then they perform their tasks in the background as well as other programs are interacting with system in the current time.

Advantages of Multi User OS

  • Multi user operating system is very useful in offices or library, because it can be handled printing jobs with effective manner.
  • Multiple users can access same copy of document on one computer system. For example, if some PPT file is stored in the one computer, then other user can watch this PPT on other terminals.
  • Multi user O/S is used in the ticket reservation system.
  • Multi user O/S is also used in the some functionality of Airlines.
  • Entire system does not get halt, if one computer gets fails in own network system.
  • All company’s managers also can use the multi user operating system for searching manufacturing records, because this record is stored in one system but staff no bound on one computer, they can access other terminals those records.

Disadvantage of Multi User OS

If, virus attacks on one computer, then this virus spreads on entire network system simultaneously, and finally all computer system can get fails.

All information of computer is shared publicly, so your private data is shared on the entire network.

 If you are having an issue with installing a printer or getting other issues dealing with a printer or printer setup on the computer, try this troubleshooter.  If a step doesn't apply, skip to next step  1. Turn computer off  2. Turn printer off 3. Disconnect power to printer for 2 minutes  4. Turn printer back on  5. Wait one minute  6. Make sure all connections are good  7. If your printer has both parallel and USB connectors, only have one of the two connected and not both. The USB is faster. (most new systems do not have parallel connections)  8. Turn computer back on  9. Make sure the printer has ink  10. Is the printer networked? If so is it connected to the network via computer or router. If it is connected via a computer and the computer is off, the other systems will not see it.  11. Make sure the dependencies to the print spool is started  12.

RESISTOR TESTING

1- Visual inspection: Checks for missing or any burning on resistance.   2- Using Digital Multimeter: You can check the resistor resistance by selecting the ohm range in the digital multimeter, If the resistor is in circuit, you will generally have to remove the resistor so you are testing only the resistor value and not the other components in the circuit.   Connect test probes across the two points of the resistor as shown in the photo, polarity isn’t important, value of resistance shown is 9.86 kΩ. Note: All resistors have a specific tolerance rating. The tolerance rating is marked by a color band on the end of the resistor’s body, normally the band is gold indicating 5 % tolerance. If the tolerance band is silver, then the rating is 10 %. How to test SMD Resistors: Because of the small size of SMD resistors, there is often not room for the traditional color band code to be printed on them. Therefore, new resistor SMD codes were developed. The most commonly seen codes are the three

IP Address: internet protocol

   What is an IP address?     An IP (Internet Protocol) address is a unique numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication.     It serves two main functions: identifying the host or network interface and providing the location of the device in the network. Types of IP addresses:     IPv4: This is the most common type of IP address used today. It consists of four sets of numbers separated by periods (e.g., 192.168.0.1). IPv4 allows for approximately 4.3 billion unique addresses.     IPv6: With the increasing number of connected devices, IPv6 was introduced to address the depletion of IPv4 addresses. It uses eight sets of numbers separated by colons (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334). IPv6 provides a significantly larger address space. How IP addresses work:     When a device wants to communicate with another device over the internet, it needs to know the destination device's IP ad
