What is the primary purpose of cache memory?

• To store data permanently for the operating system.
• To increase the size of the hard drive.
• Improve CPU speed

• To manage network connections efficiently.

Which of the following is NOT a level in the memory hierarchy?

• Flash Memory

• Registers

• DRAMS

• Optical drive

What type of memory is DRAM primarily used for?

• Cache Memory

• Secondary Storage

• Main Memory

• Registers

Which of the following characteristics distinguishes SRAM from DRAM?

• SRAM is slower than DRAM

• SRAM does not require refreshing

• SRAM is less expensive

• SRAM has higher capacity

What does EEPROM stand for?

• Enhanced Erasable Programmable Memory
• Electrically Erasable and Programmable Read-Only Memory

• Erasable Electronic Read-Only Memory

Which characteristic is true for secondary storage devices?

• They typically offer larger capacity than primary memory

• They retain data even after power loss

• They are typically used for temporary data storage

• They are faster than hard drives

Temporal locality refers to:

• Accessing the same memory location within a short time period

• Accessing data from external storage devices
• Accessing data in a random manner
• Accessing the same memory location only once

What is one disadvantage of using DRAM?
