P1 - Identify the key features of event driven programming such as events, event loops and event handlers

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 very important to be able to run different applications on your phone or computer etc. so you can run multiple programs at the same time, it manages internal memory, it runs the input and output of attached devices like your phone or printer by transferring data. And lastly it also enables you to run more than 1 processor at the same time by dividing the program. So as you can see operating systems are very important to improve and be able to run your PC.

Microsoft has been the world leader with respects to computer Operating Systems Software, and has increasingly become more efficient and precise with each release. Microsoft released their first version of the Windows Software (November 20th, 1985). This operating system was an anomaly at the time, and has progressed to the point that it is used worldwide on most computers in the world. All of the leading competitors have used Windows as a benchmark and have either copied its features or expanded upon them.

SE applications are used in a wide range of activities, from industry to entertainment. Software applications improve user productivity and quality of life. Application software examples: office suites, video games, and the world wide web. System software examples: embedded systems and operating systems.

When looking at an Operating System one could often say that an Operating System is a large sum made up of small separate parts. Much like how Knuth describes computer science being the “wall of mini stones”. The Operating System, or the “OS” can be defined as “software that communicates with the hardware and allows other programs to run”. (TechTerms.com, 2012) The Operating System makes use of two modes known as User Mode and Kernel Mode in order to

This type of operating system is used in embedded computer systems. It is operated on PDAs with less autonomy. It is compact and efficient to design .

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.

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

An operating system (sometimes abbreviated as "OS") is the program that, after being initially loaded into the computer by a boot program, manages all the other programs in a computer. The other programs are called applications or application programs. The application programs make use of the operating system by making requests for services through a defined application program interface (API). In addition, users can interact directly with the operating system through a user interface such as a command language or a graphical user interface (GUI).

Windows is the most widely used Operating System in the world, It’s initial introduction was in 1981 as a command-line interface; the GUI (graphical user interface) was introduced in 1985 and has seen 26 different versions.

The operating system can be defined as a collection of written procedures, linked together into a single large executable binary program.

The computer is made up of many components and the operating system is just an interface between the user and the computer hardware. Software that runs on a computer must be designed to meet the requirements of the operating system and not exceed the hardware limitations to run effectively on a
