Operating System
Linux Operating System, Operating System Basic Question. A Linux operating system is a system software that acts as an intermediary between the user and the computer hardware. The purpose of a Linux operating system is to provide an environment so that a user can execute the program in a convenient way and efficiently. |
| Operating System |
The computer has no existence of itself. This is just a group of hardware such as a keyboard, monitor, CPU etc. The operating system establishes a connection between all the hardware. Due to the operating system, the user does not need to keep the information on different parts of the computer, as well as the user can do all his work without stress.
The operating system records the status of each resource of the computer system and also decides when and for how long the computer resources will be controlled. The Operating system is the first program that is loaded into the computer's memory after the computer is switched on.

1- Features Of Operating System:-
(A)- Multi-Tasking:-
Interactive control in more than one process kept in memory is known as multi-tasking. Before deleting the control from a program, its former condition is secured, when control comes on this program, the program stays in its former state. In multitasking, the user feels like all the work is going on simultaneously.
(B)- Multi-Processing:-
For more than one work execution at one time, more than one CPU is present on the system. This technique is called multi-processing. Multi-processing system has been built keeping in mind the multi-processor system. Therefore, due to the availability of more than one processor, the input-output and processing are coordinated between the three functions. The system using more than one CPU of the same type is known as the symmetric multi-processor system.
(C)- Memory Management:-
Programs and statistics have to be stored in memory before executing. Most operating systems provide more than one program to stay in memory at one time. The operating system determines that the memory being used does not overwrite the memory used when the program is exhausted.
(D)- Multi-Programming:-
Multi-programming is the process of operating more than two processes at one time. Based on special techniques, CPU It is decided by which of these programs to run the program. At the same time, the CPU When a program runs, the output division receives the result of the completed program from CPU, and the input division uses any other program as. Enters CPU In this process, all the components of the CPU are fully engaged.(E)- Distributed:-
Distributed working framework deals with a gathering of particular Computers and influences them to have all the earmarks of being a solitary Computer. The advancement of organized Computers that could be connected and speak with each other offered to ascend to appropriated figuring. Circulated calculations square measure done on in way over one machine. At the point when Computers in a gathering work in participation, they frame a conveyed framework.(F)- Real-Time:-
The process of the real-time operating system is very fast, the real-time operating system is used when the computer is being controlled by a certain work. The result of this type of experiment is immediately received. And this result is immediately used in its calculations. The process to be controlled when needed can be changed. Through this technique, the work of the computer is consistently taking data, calculating them, arranging them in memory, and giving directions based on the results of the calculation.
(G)- Security Management:-
The operating system installs data security and integrity. That is, the operating system keeps different programs and data in such a way that they can not interfere with each other. Apart from this, The Operating system prevents data from being deleted by the wrong user.
2- Basics of Popular Operating Systems:-
- (Windows, Linux, Mac OS)
(A)- Windows:-
Windows is a working operating system planned by Microsoft. The working operating system is the thing that enables you to utilize a Computer. Windows comes preloaded on most new computers which makes it the most prevalent working operating system in the world. Windows makes it conceivable to finish a wide range of regular errands on your Computer. For instance, you can utilize Windows to peruse the Internet, browse your website, tune in to songs, play favorite games, alter advanced photographs thus substantially more. Windows is likewise utilized as a part of numerous workplaces since it gives you access to profitability devices, for example, timetables, word processors, and excel.(B)- Linux:-
Linux is a multiuser multitasking operating system. The Linux operating system was created by Linus Benedict Torvalds in 1991. He posted data about his task on a newsgroup for Computer understudies and software engineers and got support and help from volunteers who prevailing with regards to making a total and practical portion. Linux is Unix-like, however, was produced with no Unix code, dissimilar to BSD and its variations., Linux is an open source operating system that can allow Linux to access without any permissions. Despite the fact that assessments propose that Linux is utilized on just 4.72% of all "work area" (PC) Computers, it has been generally embraced for use in servers and implanted frameworks, for example, PDAs. Linux has superseded Unix on numerous stages and is utilized on most supercomputers including the main 385. Huge numbers of similar Computers are likewise on Green500 (yet in the diverse request), and Linux keeps running on the best 10. Linux is additionally usually utilized on other little vitality effective Computers, for example, cell phones and smartwatches. The Linux part is utilized as a part of some prevalent circulations, Debian, for example, Red Hat, Linux Mint, Ubuntu, and Google's Android, Chrome operating system, and Chromium operating system.(C)- Mac OS:-
Mac OS is the working system software(OS) that powers each Macbook. Mac OS, the working operating system created by the American computer organization Apple Inc. The OS was acquainted in 1984 with run the organization's Macintosh line of computers.
It gives you a chance to do things you basically can't with other computers That is on the grounds that it's outlined particularly for the equipment it keeps running on and the other way around. macintosh OS accompanies a whole suite of flawlessly designed apps. It works as an inseparable unit with iCloud to keep photographs, archives, and another stuff breakthrough on devices. It influences your Mac to work like enchantment with your iPhone. Furthermore, it's been developed starting from the earliest stage protection and security in mind.
