Keywords

💡Computer System

A computer system refers to the combination of hardware, software, and users that work together to perform data processing tasks. In the video, the concept of a computer system is central to understanding how computers operate, as it highlights the collaboration between different components such as hardware (physical devices), software (programs), and the user. The system is explained as a crucial aspect of digital technology that enables various activities in our daily lives.

💡Hardware

Hardware refers to the physical components of a computer that can be touched and seen, such as the CPU, RAM, mouse, and hard disk. The video explains hardware as one of the essential parts of a computer system, necessary for the machine to function. Without hardware, the computer would be a non-functional device. Hardware is compared to the human body, which needs a soul (software) to be functional.

💡Software

Software is the non-physical component of a computer, consisting of programs and codes that instruct the hardware on how to perform specific tasks. The video emphasizes the importance of software as the 'soul' of the computer, enabling it to perform its functions.
