Functions Of A Operating System

Operating Systems are complex pieces of software that are designed for powerful hardware, easily capable of running many programs at once, the prioritize hardware task requests known as ‘system calls’ and allocate them memory space or processing time as needed.

The Operating system is one most important parts of anything that runs on technology. It manages the computers memory and processes the information for the software and hardware. There is different operation system for pc, tablets, smart cars, and smartphones.

A computers operating system (OS) is the core of the computer and is more than just software. The OS controls the computer’s memory and processes as well as its hardware and software. It is the brain of the computer. Software applications on the other hand perform a certain task. Ex. Google Chrome provides internet and Adobe allows PDF files to be read (among other things). The OS is what makes all of these applications work successfully and accomplish whatever the application is designed to accomplish.

Operating systems are vital to the use of computers, they tell the machine what it is, what language, where the programs are, when things are stored, how to do things, the instruction codes to do everything. The system is in charge of security such as ensuring that unauthorised users do not access the system. There are many types of operating systems, a few are listed below:

Windows has the option to change its background and also font size for those who are visually impaired, another notable function is the ability to increase icon size to make it much easier to see and read.

BIOS (Basic Input Output System): BIOS set up the computer and boot the operating system it also handles the system setup process including driver loading.

i) Disk : file server, virtual disk server, feature on interest server and so on

Identifying and describing key features of operating systems and common application software as they relate to the management of information.

Files and folders are unorganised as it does not have a particular share drive therefore it is hard to locate files and is stored on individuals’ computer.

The display and readability features of windows operating system are mainly designed to adjust the size of items on the screen. The display and readability features consist of different options such as font style, icon size, screen resolution, high contrast schemes and Microsoft Magnifier.

In addition, the Operating System allows the use of

The operating system is the set of instructions that direct the computer to accomplish specific tasks such as document production and spreadsheet calculations.

There are advantages and disadvantages of Linux operating system. The first advantages of Linux operating system is it is free to obtain [3]. Unlike Microsoft, Linux distribution can be installed on more than one computer without any cost charged [3]. Besides that, Linux can run perfect on old computers and enable users to browse the Internet, email, play games, create and edit documents and others [3]. In security aspect, Linux is much stronger than Windows. This is because Linux uses smart authorization management [5], which requires user to authorize any action that might harm their computer by entering the password [5]. By this way, users are less likely to be tricked into installing malware and running virus programs [5]. In addition, if user faces any technical problem, they can visit any of the Linux online forums and post the

This paper will discuss three main operating systems, Windows, Linux, and OS X. All three of these operating systems have features which are unique unto themselves. Although there may be arguments as to which one of these three operating systems is better it really all comes down to what features are needed for each user. This paper will describe the features that each of these operating systems has to offer.

Because Mac is a BSD-style operating system, it is also a multi-user operating system. However, since Mac is more of a desktop OS, it is not common to see many users accessing the system at the same time. In spite of this, the process management in Mac is very similar to Linux because they are both UNIX-based operating systems. One key difference is that with Mac most people would modify and control processes from with the GUI and most users would modify the processes using ps on Linux.
