Solutions
S1. Ans. (a)
Sol. Cache Memory has shortest access time. Cache memory, also called CPU memory, is random access memory (RAM) that a computer microprocessor can access more quickly than it can access regular RAM.
S2. Ans.(a)
Sol. An address bus is a computer bus architecture used to transfer data between devices that are identified by the hardware address of the physical memory (the physical address), which is stored in the form of binary numbers to enable the data bus to access memory storage.
S3.Ans. (b)
S4. Ans. (a)
S5. Ans. (a)
Sol. Memory is the place where data can be stored and later retrieved. Memory can be of classified into register, cache, main memory, etc.
S6. Ans.(a)
S7. Ans.(c)
Sol. PROM or programmable ROM (programmable read-only memory) is a computer memory chip that can be programmed once after it is created. Once the PROM is programmed, the information written is permanent and cannot be erased or deleted.
S8. Ans. (b)
Sol. ROM is non-volatile memory, meaning that it stores data both while the power is on and when the power is switched off. Unless ROM gets erased, it never forgets data.
S9. Ans. (c)
Sol. ROM is non-volatile memory, meaning that it stores data both while the power is on and when the power is switched off. Unless ROM gets erased, it never forgets data.
S10. Ans.(c)
S11.Ans.(c)
Sol. stored data in secondary storage is not deleted when power turns off.
S12. Ans. (b)
S13.Ans.(a)
Sol. Cache memory, also called CPU memory, is random access memory (RAM) that a computer microprocessor can access more quickly than it can access regular RAM. This memory is typically integrated directly with the CPU chip or placed on a separate chip that has a separate bus interconnect with the CPU.
S14. Ans. (d)
S15. Ans.(d)
Sol. Read-only memory (ROM) is a type of storage medium that permanently stores data on personal computers (PCs) and other electronic devices.
