Computer Systems Organization - Memory

  1. These are sequential number of locations inside the memory, each of which are a specific number of bits wide.
    Address Locations
  2. (T/F) The more number of bits per location affects the speed at which data can be moved from one location to another in a computer system.
    True
  3. (T/F) In general, the more bits per location the faster data can be transferred.   Each memory location is referred to as an address, and generally expressed in hexadecimal notation (using base 16 numbers).
    True
  4. The processor selects a specific address in memory by placing the address on the _________
    address bus
  5. The total number of address locations which can be accessed by the processor is known as its ___________.
    physical address space
  6. This refers to how long it takes the processor to read or write to a specific memory location within a chip.
    Access Time
  7. This refers to whether or not the contents of the memory is lost when power is turned off.
    Votality
  8. A type of computer memory that can be accessed randomly; that is, any byte of memory can be accessed without touching the preceding bytes.
    Random Access Memory
  9. ______ is the most common type of memory found in computers and other devices, such as printers.
    RAM
  10. It loses its data once the power is removed, so it is a volatile memory
    RAM
  11. A type of physical memory used in most personal computers.
    Dynamic RAM (DRAM)
  12. The term _______ indicates that the memory must be constantly _________ (reenergized) or it will lose its contents.
    dynamic and refreshed
  13. a type of memory that is faster and more reliable than the more common DRAM (dynamic RAM).
    Static RAM (SRAM)
  14. The term _______ is derived from the fact that it doesn't need to be refreshed like dynamic RAM.
    static
  15. A _______ is one of a small set of data holding places that are part of a computer processor .
    register
  16. A ______ may hold a computer instruction , a storage address, or any kind of data (such as a bit sequence or individual characters).
    register
  17. (T/F) Some instructions specify registers as part of the instruction.
    True
  18. A special high-speed storage mechanism. It can be either a reserved section of main memory or an independent high-speed storage device.
    Cache
  19. Fast and small compared to main memory; acts as a buffer between the CPU and main memory: it contains the most recent used memory locations (address and contents are recorded here)
    Cache
  20. ______ stores data using virtual addresses
    Logical cache (virtual cache)
  21. _______ stores data using main memory physical addresses
    Physical cache
  22. Every address reference goes first to the cache; if the desired address is found there, then it is called a ________
    cache hit
  23. A ________ occurs when the address is not found.
    cache miss
  24. ________ refers to the reuse of specific data, and/or resources, within a relatively small time duration.
    Temporal locality
  25. (T/F) Most software exhibits temporal locality of access, meaning that it is likely that same address will be used again soon
    True
  26. ________ refers to the use of data elements within relatively close storage locations.
    Spatial locality
  27. When the update must be generated to the main memory as well as to the cache
    Write-through
  28. When the update is generated only to the cache, that will propagate it to the main memory at a latter time
    Write-back
