Application software
System Software – it is designed to run a computer’s hardware and application software, and make the computer system
available for use. It serves as the interface between hardware, application software, and the user.
– a software that controls and coordinates the computer hardware devices and runs other software and applications on a computer. It is the main part of system software and a computer will not function without it.
– a software program that is designed to control a particular hardware device that is attached to a computer.
– a type of system software that helps set up, analyze, configure, strengthen, maintain a computer and performs a very specific task (e.g. antivirus software, backup software, memory tester, screen saver, etc.). Hardware (the physical parts of a computer), software (the programs that can be run on a computer) and the Operating System that allows software and hardware to communicate: TheSchoolRun's Billy Rebecchi explains what your child learns in KS1 and KS2 computing and how you can develop their understanding at home. What are software, hardware and Operating Systems?There are very clear differences between software, hardware and an operating system that are important to understand when learning about computer science. When discussing software we are mainly talking about programs that can be run on a computer. Hardware is the physical parts of a computer, such as the processor, memory modules and the screen. The Operating System is often described as a translator; it translates the language of the hardware (binary numbers) into the language of the software (written programs) and then displays it in a way that humans can understand (text, images and sound). How do children learn about hardware?In KS1 the very basic hardware components of a computer are introduced:

In KS2 children are introduced to slightly more complicated parts of a computer:
Although there are lots of devices that meet the criteria above, in primary years your child will only learn about a small number of them. There is no
set list of devices that are learned about, however they will generally be the ones in this table: An example of an activity that may be run at both KS1 and KS2 would be to have the physical devices from the table above laid out on a table. In corners of the room or on multi-coloured boxes a teacher may place labels for inputs, outputs, processing devices and storage. The students will then have to look at each physical device, select what it is and the device's function and finally decide which category it belongs to. How do children learn about software?In KS1 software is described to your child as being a ‘set of instructions run by a computer’. Your child may understand that programming is linked to software, as when they write basic programs for a turtle robot they are effectively writing software for it. However software is an abstract concept and can be very difficult for a young child to understand, as there is no concrete way to look at it; it doesn’t really exist. Whilst we can write a computer program and print the code onto pieces of paper, this would not be of any use to us, as without running the code on a piece of hardware it doesn’t actually do anything. The code written for software, whilst extremely valuable to whoever wrote it, is completely useless until run on a computer. In other words, software isn't the code it's written in but the result of having that code running on our computer, asking for input and showing output to the screen. This is an exceedingly difficult concept, so until KS2 children's understanding of software is not developed much further than a description and some examples. Even at KS2, the idea does not go much beyond this, but as long as students are learning about software hand in hand with algorithms and programming, then the foundation knowledge required to understand what software is starts to develop. Whilst there are no set tasks that can be used to teach students about software, as students start to write more and more code their understanding of software being something they can build and hardware being something that is a physical object will develop naturally and will be
reiterated multiple times by teachers throughout their early computing. How do children learn about Operating Systems in KS1?An operating system (OS) is generally described as a translator, however it is actually a very large and complicated piece of software. Its main job is to allow communication between the different parts of a computer. At KS1 level your child will be introduced to the concept of the OS through reference to the UI (User Interface). The UI is what allows us to communicate with a computer by showing us information and giving us things to click. If we want to go on the Internet then by clicking on the Internet Explorer icon the OS will load the browser for us and show it on screen. When you click inside the Internet Explorer window the OS tells the program, allowing it to then calculate what it should do next. When the program makes changes it then asks the OS to show these changes on the screen. This is introduced very simply at KS1 level through a series of tasks that will have your child perform basic functions on the computer, such as loading programs and using menus. Discussion will be had regarding what is happening when you click on something on screen and questions will be asked such as “How does the program know where your mouse is?” and “What tells the computer when you have pressed a key on the keyboard?” How do children learn about Operating Systems in KS2?At KS2 this learning will be taken further and the concept of the OS being a translator will be introduced more thoroughly. An example of an OS learning activity at KS2 would be to have students stand up at the front of the class and be given a role. For example, one student could draw a picture, one student could provide pieces of paper, one student could be a communicator and one student could be a middleman for the other three.
In this example there are a few analogies that we can use: • The middleman is the Operating System. They communicate with all the other members of the team (components of the computer) and deal with all requests and communication. • The communicator is our input device. In a computer they could be the mouse, receiving a request to start drawing on the screen. • The piece of paper is our output. In a computer this could be the screen. When the middleman asks whether there is paper available this could be the OS checking that there is nothing else on screen. • The drawer is our software. This handles the input from the user and produces an output to the screen. Hardware, software and the OS: what kids learn in each year groupPlease note that the following guidelines for what is taught in each primary year is for guidance only and may not be representative of the way computing is taught at your child’s school.

3 Year 4 Year 5 Year 6 What is the operating system of a computer called?An operating system (OS) is the program that, after being initially loaded into the computer by a boot program, manages all of the other application programs in a computer. The application programs make use of the operating system by making requests for services through a defined application program interface (API).
How the operating system works with the computer's hardware and software?The operating system (OS) manages all of the software and hardware on the computer. It performs basic tasks such as file, memory and process management, handling input and output, and controlling peripheral devices such as disk drives and printers.
What is an operating system how is it related to computer hardware?Operating System, as name suggests, is simply a system software runs on computer that manages all application programs in computer and provide interface among user and hardware. Computer Hardware consists of physical parts of computer. Operating System is a translator between computer user and hardware.
What is the operating system and system type running on your computer?To find out which version of Windows your device is running, press the Windows logo key key + R, type winver in the Open box, and then select OK.
