An operating system is one of an important system that should have inside a computer. It contains instructions that coordinate all the activities among the computer hardware resources. Without an operating system, all of the computers cannot be used or started. The role of the operating system is to manage the software and hardware so that easy to control all of the activities depending on what the programs need (Curt Franklin, 2000).
Next, there are four basic functions of the operating system. Memory management takes part in main memory which is Random Acess Memory (RAM). It retains the space of the main memory and checks whether it is valid and legal for the memory space request. The memory manager also can track the usage of memory by sections.
Besides, processor management is also essential managers of the operating system. Basically, it tracks the processor status that takes part of allocating Central Processor Unit (CPU). The main responsibilities of processor manager managed by Job Scheduler and Processor Scheduler. The Job Scheduler handles the jobs as they enter the system while the Processor Scheduler manages each process within the jobs.
Furthermore, device management supervises all of the resources such as I\O (input and output)

So, the best things about Android because it uses the open-source platform and easy to access the Google Applications. Then, everyone can afford an Android mobile phone because the price is not expensive. In contrast, Android has a low security and fakes app might be installed inside the mobile phone to take our information from unknown resources. It also has a complex layout and animations that hard to code into it. Moving on to iOS, it has an excellent User Interface (UI) and generates less heat than Android but if iPhone malfunction, the repair cost must be expensive. Last but not least, it's not flexible for others because it only supports iOS
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.
As the OS control controls over all actions of computer so it is able to supply the detail or the elements that is needed by software to run from the hardware interface. Then it is acts as a resource manager as it is important component of a computer which controls all the components of the computer system. When the hardware provides the basic computing resources, the application program routine define the ways in which these resources are used to solve the computing problems of the users and the operating system controls and coordinate the use of hardware among the various application programs for the various users. It also handles storage management by controlling the storage management. Either than that, it is enables user to perform various tasks such as creating directories and files, copying and moving files, renaming files and deleting files. Then it keeps track of the exact location of files o hard drive through specific type of file system. The system tools are used to monitor computer performance, debug problems, or maintain parts of the system. A set of libraries or functions which programs may use to perform specific tasks especially relating to interfacing with computer system components. Despite that it provides a set of reusable system
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:
The primary functions of the management process consist of planning and strategizing, organizing, leading and controlling. The planning process helps
The operating system is the set of instructions that direct the computer to accomplish specific tasks such as document production and spreadsheet calculations.
An operating system is a network of software that acts as the manager for all hardware and software on your computer.
Operating System is a main computer program that communicates with the hardware to help the computer run.
If we explore opinions from Android users and iPhone users, you’ll find that they are very fond of the phone that they possess. In most cases, people either love having an Android or they love having an iPhone. Except, this is all based on the software of each phone, for they have major similarities and differences.
The (OS) operating system is the best example of system software. An operating system manages a computer’s hardware and software and provides sources for computer programs. Most application programs require an operating system to function. There are numerous operating systems (OS) one may choose to install on their computer. Each OS will have different looks and functions that differ from the others. Windows 10 is a popular OS that is used widely around The United States. System software and application programs are the two main types of system software.
An Operating System is the software that manages the sharing of the resources, processes system data and user input, and responds by allocating and managing tasks and internal system resources as a service to users and programs of the system (UzEE, 2007).
The operating system can be defined as a collection of written procedures, linked together into a single large executable binary program.
[1] The low-level software that manages the hardware resources of a computer in an efficient manner and schedule different tasks is known as an OS (operating system) of a computer. Without an OS a computer is not able to do anything and it is useless. Main hardware components of an operating system are;
An operating system (OS) is a software program that enables the computer hardware to communicate and operate with the computer software. OS is the software that supports a computer 's basic functions, such as scheduling tasks, executing applications, and controlling peripherals. It is a program that acts as an interface between the user and the computer hardware and controls the execution of all kinds of programs in computer/computer devices. The users of the computer interact with the system and application software which are installed and function in OS. Likewise for the hardware such as Keyboard, printers, mouse, CPU, registers, disks, monitors, RAM and other I/O devices to be functional they need an operating system in which their systems are embedded (fig. 1 shows the interaction)
An operating system (OS) is system software that manages computer hardware and software resources and provides common services for computer programs. The operating system is a component of the system software in a computer system. Every general-purpose computer must have an operating system to run other programs and applications. Operating systems perform basic tasks, such as recognizing input from the keyboard, sending output to the display screen, keeping track of files and directories on the disk, and controlling peripheral devices such as disk drives and printers.
An operating system is an interface between a user and the hardware of a computer. It is just a set of software that manages computer hardware and controls the operations on the computer. Operating system is the base of the application programs because they cannot contact the hardware directly. It does not do any work itself; it just provides an environment in which the other programs on a computer can run. Therefore, when a user enters or sends a command the operating system makes sure that the command is executed or not, if not it displays a message explaining the error. Without operating system a computer is of no use it is just a metal block.
