The short-term memory of a computer is known as A: RAM (Random Access Memory). RAM is volatile memory, meaning it temporarily stores data that the CPU (Central Processing Unit) is actively using or needs quick access to. This allows for rapid reading and writing of data, crucial for the computer's operational speed and multitasking capabilities. However, all data stored in RAM is lost when the computer is powered off.
B: ROM (Read-Only Memory) stores permanent, non-volatile instructions essential for booting the computer. C: Floppy disks are outdated, external, non-volatile storage. D: Hard Disk drives provide long-term, non-volatile storage for the operating system, applications, and user files, not for active, temporary processing data.
