System Software ( Os )

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:

The program by its self is just instructions writing in code where a process is an active program which has been executed. The CPU executes one instruction at a time until the process completes.

The processor (otherwise known as CPU) is the very soul and performance core of the computer system; it is what allows the operating system and other software applications to-run. Every program demands dedication from the processor to decode commands that are then actionedinside the CPU to make them work.When a program is running, the CPU has to make every command work consistently one after the other. However, modern processors have the power to process commands side by side. This means that the quicker the commands are executed, the quicker the program responds to the user. Central Processing Units (CPUs) play an important role when it comes to maintaining

The processor (CPU) is essentially the brain of a computer system. The role of the CPU is mainly to process everything from basic instructions to complex function. The well known measure of the CPU is clock speed and it is measured in MHz or GHz. The different manufacturers of the CPU are Texas Instruments, Intel Corp, Centaur Technology etc..

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

A multiprogramming is used to keep the CPU busy most of the time, i.e. increase utilization of system CPU. This is due to the fact that multiprogramming is performed by job scheduling, i.e. with the subset of all the jobs kept in memory. Thus when CPU has to wait, then OS switches to another job for keeping CPU busy.

Multiprocessor (having more than one processor) refers to a system with two or more processors or CPUs. Multiprocessing (supporting multiple processes) refers to a system that can process one or more tasks at a time.

What is an Operating System (OS) a person may ask? Having an operating system, helps to control applications that run on the software and hardware that are on any user’s computer. These applications are set within a layered appearance, just as a hierarchy looks like. This is how it looks:

On personal computers, there are two main types of software: operating systems, and applications software. Application software is a program designed to complete a specific purpose under control from a user. Application software is specialized, as in it perform a specific task. For example, Microsoft Word is a word processor, and is used for typing. Windows explorer is used to browse saved files, and does that job well.

5. When the processing is complete the CPU reloads the previously suspended program’s registers/commands/data, and processing continues from where it left off.

When you start a pc with an OS, it allows you to do projects like:

Operating systems, (“OS”) are the management programs of a computer. First it is booted into the computer by a boot program, and then it manages all other programs on the computer. These other programs are called applications, and they utilize an operating system by making requests for process service power through an API, or application program interface. Users then interact directly with an operating system through a graphical user interface or command language.
