Study Notes
- RAM (Random Access Memory) is a type of memory chip used in computers for short-term data storage while the PC is switched on, allowing for quick access to data.
- There are different types of computer memory, such as primary memory (RAM and ROM) used for processing data and secondary memory (offline memory like hard disks) used for storage.
- Hard disks are large storage devices inside computers that hold a significant amount of information, with fast access speeds compared to floppy disks.
- The main memory in a computer consists of memory cells with unique addresses where data is stored in binary digits (bits), and the capacity is measured in kilobytes (KB) or megabytes (MB).
- Computers are composed of four major components: Input units (like mouse and keyboard), Central Processing Unit (CPU) which controls operations, Secondary Storage for permanent data storage, and Output Units for transferring data to devices like printers and monitors.
Explore the concept of Random Access Memory (RAM) in computers, how it functions as a temporary storage allowing quick access to data during the PC's operation, and its differences from hard disks. Learn about the various types and sizes of memory based on different motherboard specifications.
