VERIFIED ANSWERS
Question 1
Register File
Correct Answer
A state element that consists of a set of registers that can be read and written by supplying a register number to be
accessed.
provides 1024 scalar 32-bit registers for up to 64 threads.
Question 2
machine language
Correct Answer
The language made up of binary-coded instructions that is used directly by the computer
Question 3
system software
Correct Answer
The set of programs that enables a computer's hardware devices and application software to work together; it includes
the operating system and utility programs.
Question 4
operating system
Correct Answer
(computer science) software that controls the execution of computer programs and may provide various services
Question 5
Assembly Language
Correct Answer
Programming language that has the same structure and set of commands as machine languages but allows programmers
to use symbolic representations of numeric machine code.

,Question 6
IBM 360/91
Correct Answer
Introduced many new concepts, including dynamic detection of memory hazards, generalized forwarding, and reservation
stations. Tomasulo's algorithm
The internal organization of the 360/91 shares many features with the Pentium III and Pentium 4, as well as with several
other microprocessors. One major difference was that there was no branch prediction in the 360/91 and hence no
speculation. Another major difference was that there was no commit unit, so once the instructions finished execution,
they updated the registers.
Question 7
Dynamic Random Access Memory (DRAM)
Correct Answer
Memory built as an integrated circuit; it provides random access to any location. Access times are 50 nanoseconds and
cost per gigabyte in 2012 was $5 to $10.
Multiple DRAMs are used together to contain the instructions and data of a program. In contrast to sequential access
memories, such as magnetic tapes, the RAM portion of the term DRAM means that memory accesses take basically the
same amount of time no matter what portion of the memory is read.
Modern DRAMS consist of rows in each bank
Question 8
frame buffering
Correct Answer
A portion of RAM containing a bitmap that drives a video display. It is a memory buffer containing a complete frame of
data.
The image to be represented onscreen is stored in the frame buffer, and the bit pattern per pixel is read out to the
graphics display at the refresh rate. The animation below shows a frame buffer with a simplified design of just 4 bits per
pixel.
Question 9
Datapath
Correct Answer
The component of the processor that performs arithmetic operations
Question 10
Control
Correct Answer
The component of the processor that commands the datapath, memory, and I/O devices according to the instructions of
the program.

,Question 11
Integrated circuit
Correct Answer
Also called a chip. A device combining dozens to millions of transistors.
Question 12
Central processor unit (CPU)
Correct Answer
Also called processor. The active part of the computer, which contains the datapath and control and which adds numbers,
tests numbers, signals I/O devices to activate, and so on.
Question 13
Static random access memory (SRAM)
Correct Answer
Also memory built as an integrated circuit, but faster and less dense than DRAM.
Question 14
Instruction set architecture
Correct Answer
Also called architecture. An abstract interface between the hardware and the lowest-level software that encompasses all
the information necessary to write a machine language program that will run correctly, including instructions, registers,
memory access, I/O, and so on.
Question 15
Application binary interface (ABI)
Correct Answer
The user portion of the instruction set plus the operating system interfaces used by application programmers. It defines a
standard for binary portability across computers.
Question 16
Volatile memory
Correct Answer
Storage, such as DRAM, that retains data only if it is receiving power.
Question 17
Nonvolatile Memory
Correct Answer
A form of memory that retains data even in the absence of a power source and that is used to store programs between
runs. A DVD disk is nonvolatile.

, Question 18
Magnetic disk
Correct Answer
Also called hard disk. A form of nonvolatile secondary memory composed of rotating platters coated with a magnetic
recording material. Because they are rotating mechanical devices, access times are about 5 to 20 milliseconds and cost
per gigabyte in 2012 was $0.05 to $0.10
Question 19
Main memory
Correct Answer
Also called primary memory. Memory used to hold programs while they are running; typically consists of DRAM in today's
computers.
Question 20
Secondary memory
Correct Answer
Nonvolatile memory used to store programs and data between runs; typically consists of flash memory in PMDs and
magnetic disks in servers.
Question 21
Flash memory
Correct Answer
A nonvolatile semiconductor memory. It is cheaper and slower than DRAM but more expensive per bit and faster than
magnetic disks. Access times are about 5 to 50 microseconds and cost per gigabyte in 2012 was $0.75 to $1.00.
Question 22
Single Instruction Single Data (SISD)
Correct Answer
A uniprocessor
Question 23
Multiple Instruction Multiple Data (MIMD)
Correct Answer
A multiprocessor.
Question 24
Single Program, Multiple Data Streams (SPMD)
Correct Answer
The conventional MIMD programming model, where a single program runs across all processors.
