Everything you do on your computer will rely on both hardware and software. For example, right now you may be viewing this lesson in a web browser software and using your mouse hardware to click from page to page.
As you learn about different types of computers, ask yourself about the differences in their hardware. As you progress through this tutorial, you'll see that different types of computers also often use different types of software. When most people hear the word computer , they think of a personal computer such as a desktop or laptop.
However, computers come in many shapes and sizes, and they perform many different functions in our daily lives. When you withdraw cash from an ATM, scan groceries at the store, or use a calculator, you're using a type of computer. Many people use desktop computers at work, home, and school. Software is a process of preparing program through instructions and data. General computers made with following types of components in hardware. Central Processing Unit maintains three kinds of activities to store the data and processing data with several kinds of operations.
PU is major part to the computer that tells about the computer to perform which task for every time. Memory is one part that store data, programs and etc. It categorized into several types those can work at special purpose.
Devices which is useful to provide input data to the computer that will be processed to provide output from other devices. Input devices give input to the computers. After process the data of input the proper output will release to the users from output devices.
It maintain above list of hardware and software components. It can be defined as a small that range up to the limited pounds. It is useful to the word processing, accounting, desktop, database management applications and etc. Number of home users use this software for play games and learn anything from internet easily. It designs forengineering applications SDLC and various kinds of applications with moderate power and graphic technologies. Computers can also store data for later uses in appropriate storage devices, and retrieve whenever it is necessary.
Modern computers are electronic devices used for a variety of purposes ranging from browsing the web, writing documents, editing videos, creating applications, playing video games, etc. They are designed to execute applications and provide a variety of solutions by combining integrated hardware and software components.
The earliest digital electronic device that could be defined as the first modern computer is the Colossus. The device used 2, vacuum tubes to perform multiple boolean logical operations to decode encrypted data. Modern computers come in all shapes and sizes to perform a broad range of different functions. Although the first ones that come to mind are desktop and laptop computers, many other less-assuming devices — such as grocery scanners, ATMs, and smart TVs — are computers as well.
The diffusion of smartphones, game consoles, wearables, and smart appliances made computers much more readily available in our daily life. A computer is made up of multiple parts and components that facilitate user functionality. Physical structure that houses a computer's processor, memory, storage, communication ports and peripheral devices.
Each of these components called devices have a different purpose, which may be either accepting inputs, storing data or sending outputs. For example, a mouse and a microphone are input devices used to record user activities and transform them into data that is transmitted to the system unit.
