14 Questions
What is the unit of transfer for internal memory?
256 bits
In some systems, what is the addressable unit?
Word
What is the size of a word typically equal to?
Instruction length
What is the relationship between the length in bits A of an address and the number N of addressable units?
$2^A = N$
For external memory, data are often transferred in what units?
Blocks
What architecture has a wide variety of instruction lengths and a word size of 32 bits?
Intel x86
Which type of memory is organized into units of data called records and requires access in a specific linear sequence?
Sequential access
What type of memory has a unique physical location-based address for each block or record and involves access to reach a general vicinity plus sequential searching, counting, or waiting to reach the final location?
Direct access
What type of memory enables making a comparison of desired bit locations within a word for a specified match and retrieves a word based on a portion of its contents rather than its address?
Associative access
Which memory type requires passing and rejecting each intermediate record to move from its current location to the desired location, leading to highly variable access time for an arbitrary record?
Sequential access
Which type of memory has a unique, physically wired-in addressing mechanism for each addressable location, allowing constant and independent access time?
Random access
Which memory type involves direct access to reach a general vicinity plus sequential searching, counting, or waiting to reach the final location, resulting in variable access time?
Direct access
What type of memory allows for selecting any location at random and directly addressing it with constant and independent access time?
Random access
Which memory type retrieves a word based on a portion of its contents rather than its address and allows making comparisons of desired bit locations within a word for a specified match?
Associative access
