What we have learnt
- PCs have diversified into desktops, laptops, and supercomputers.
- Memory types include primary (RAM and ROM) and secondary storage devices.
- RAM is volatile, while ROM is non-volatile.
Key Concepts
- -- Personal Computer (PC)
- A stand-alone microcomputer used for a variety of applications including document processing, gaming, and graphic design.
- -- Random Access Memory (RAM)
- A type of computer memory that is used to store data and program instructions temporarily while the computer is on.
- -- ReadOnly Memory (ROM)
- A type of non-volatile memory that contains instructions that can only be read, not written to.
- -- Supercomputer
- The fastest type of computer, used primarily for tasks requiring extensive computation power, such as weather forecasting and scientific simulations.
