Writing-5 "Operating system"

“Operating system” (essay-5)

I’m going to explain the basics of an operating system. Every general-purpose computer must have an operating system to run other programs and applications. It’s the chief program that manages all of the hardware and software. It has control of every process, file, section of memory and device. It is very important as it works as a middleman making sure both hardware and software interact correctly.

There are four essential managers of very operating system and they all together like a team to get jobs compeleted. The operating system works as their boss and makes sure they are all working in harmony.

·         The File manager is a type of software that manages data files in a computer system. It has limited capabilities and is designed to manage individual or group files, such as special office documents and records. It may display report details, like owner, creation date, state of completion and similar features useful in an office environment.

·         The Memory manager  is the function responsible for managing the computer's primary memory. The memory management function keeps track of the status of each memory location, either allocated or free. It determines how memory is allocated among competing processes, deciding which gets memory, when they receive it, and how much they are allowed. 

·         The Process manager  is an integral part of any modern-day operating system (OS). The OS must allocate resources to processes, enable processes to share and exchange information, protect the resources of each process from other processes and enable synchronization among processes.

·         The Device manager is a feature of Microsoft Windows that detects and lists hardware devices and their status information. Device Manager is available in Microsoft Windows 95, 98, ME, 2000, 2003, XP, Vista, 7, 8, and 10.

·         Network management is the process of administering and managing the computer networks of one or many organisations. Various services provided by network managers include fault analysis, performance management, provisioning of network and network devices.

Every desktop computer, tablet, and smartphone includes an operating system that provides basic functionality for the device. Common desktop operating systems include Windows,  MAC OS, Linux and Unix. While each OS is different, most provide a graphical user interface, or GUI, that includes a desktop and the ability to manage files and folders. 

1.      Windows Operating Systems is a family of operating systems for personal and business computers. Windows dominates the personal computer world, offering a graphical user interface (GUI), virtual memory management, multitasking, and support for many peripheral devices.

2.      Mac Operating System is the official name of the Apple Macintosh operating system. Mac OS features a graphical user interface (GUI) that utilizes windows, icons, and all applications that run on a Macintosh computer have a similar user interface.

3.      Linux Operating System is a freely distributed open source operating system that runs on a number of hardware platforms. The Linux kernel was developed mainly by Linus Torvalds and it is based on Unix.

Finally, An operating system is a program that acts as an interface between the user and the computer hardware and controls the execution of all kinds of programs. This is the most important program that runs on a computer.  It also allows you to communicate with the computer without knowing how to speak the computer's language. Without an operating system, a computer is useless.
