Application software is any software added to the system that enables the user to perform a task. For example, a word processor allows the user to type a document and a browser allows the user to view web pages.
Hardware and software Computer systems consist of hardware and software. Hardware is the physical components of a computer. This is taken care of by the compiler which converts written code into binary 1s and 0s once the program follows a defined set of rules or the syntax.
These 1s and 0s are simply the voltage levels which establish the control over all the electric circuits. For example, consider a simple LED bulb connected to a battery supply and a small switch.
The bulb glows and gets turned OFF because of the variation in voltage levels in these instances. This is how voltage levels control the LED bulb. This works fine until this mechanism actually is able to operate as per your requirement. In case of computers, the entire hardware is supplied varying voltages due to which different components get activated at the same or different time instances and achieve a particular task.
Year 1 The basic parts of a computer are introduced and a definition of software is given. Year 2 The difference between input and output devices are learned and the OS is explained graphically. Year 4 Processing devices will be linked to using the OS and students will learn about how parts of the computer communicate.
Year 5 The concept of software will be revised through discussion and practice of programming techniques. Year 6 Students will tie their understanding together to be able to describe parts of a computer, what they do and how they communicate. Need help? How to videos Why join? What are hardware, software and Operating Systems? 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.

For example, a mouse has a position on the screen and is able to tell the computer when a button is clicked and which button is clicked.
A keyboard is able to send key presses to the computer. Outputs are any devices that are able to show information to the user. Good examples of these are the screen, which shows the user text and images, and headphones, which are able to play sounds for the user to listen to. You either go in an address called a URL, which stands for Uniform Resource Locator , or click on an address you've saved already. In each case, the computer now knows what you desire to do it.
The searching software then goes out to discover that address, initial stage for other hardware strategy, such as a modem, when it wants them. If it is able to discover the right address, the browser will then inform your computer to propel the information from the web side over the phone cable to your computer.
