A computer is an electronic device that receives data, follows instructions, and produces results. Data means information such as words, numbers, pictures, and sound.
Hardware means the physical parts that people can touch, including the screen, keyboard, processor, memory, and storage drive. Software means the programs and instructions that control the hardware.
A computer works through four basic actions: input, processing, storage, and output. A student may type a question, use a program to answer it, save the work, and read the result on the screen.
The processor carries out instructions like a worker following a set of steps. Memory holds information in current use, while storage keeps files for later. An operating system manages the hardware and allows users to open programs.
Students use a computer to research topics, write assignments, attend lessons, create presentations, and organize schoolwork. They can also draw, edit videos, read, and practise new skills.
Safe use includes creating strong passwords, avoiding suspicious links, protecting private information, and checking online claims before sharing them. Students should also respect copyright, which protects a creator's original work.
