  Computer Network: A computer network is a group of computers and other devices connected together to share information and resources. Computer networking is the process of connecting computers and other devices together so they can communicate and share information. It's like creating a web of linked devices that can talk to each other. Benefits of Networking Resource Sharing: Imagine you have one printer and several computers. Instead of each computer needing its own printer, they can all share one through the network. This saves money and makes life easier. Communication: Think of email, chat apps, or video calls. These are all made possible by networks that connect computers and allow them to exchange messages quickly. Data Management: Instead of saving files on each individual computer, you can store them on a central server. This makes it easier to manage, back up, and access data from any device in the network. Scalability: Networks can grow with your needs. If you ad...

                                                                           Operating System (OS) An Operating System (OS) is a software that acts as an interface between computer hardware components and the user. Every computer system must have at least one operating system to run other programs.​ An operating system (OS) is software that acts as a bridge between computer hardware and the user. It manages hardware resources and provides essential services and a user interface, enabling other software and applications to run efficiently. Examples include Windows, macOS, Linux, and Android.   History of operating system  1940s-1950s: Early Days No formal OS existed; programs were run directly on hardware. The first rudimentary "operating systems" like GMOS (General Motors Operating System) ma...

  Common Operating Machine Purposely Used for Technological and Educational Research A computer is an electronic machine that can be programmed to store, process, and retrieve data, performing tasks such as calculations, logical operations, and running applications Core Definition A computer is a programmable device that accepts input, processes it, produces output, and stores results. Modern computers are digital and electronic, capable of running programs that automate tasks. The term originally referred to humans who performed calculations, but shifted to machines as technology advanced Types of Computers Supercomputers → Extremely powerful, used for scientific simulations. Mainframes → Handle large-scale business data processing. Desktops/Laptops → Personal computing devices. Smartphones/Tablets → Portable computers with touch interfaces. Embedded Systems → Specialized computers inside appliances, cars, and medical devices. Importance of Computers Automation : Speeds up...
