eight great ideas in computer architecture
a binary representation of machine instructions
Machine language
a class of computers with the highest performance and cost, they are configured as servers and typically cost tens to hundreds of millions of dollars
supercomputer
A command that computer hardware understands and obey
Instruction
a computer designed for use by an individual usually incorporating a graphics display, a keyboard, and a mouse
personal computer
a computer inside another device used for running one predetermined application or collection of software
embedded computer
a computer used for running larger programs for multiple users, often simultaneously, and typically accessed only via a network
server
a display technology using a thin layer of liquid polymers that can be used to transmit or block light according to whether a charge is applied
Liquid crystal display
a form of memory that retains data even in the absence of a power source and that is used to store programs between runs
Nonvolatile memory
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
Magnetic disk
a liquid crystal display using a transistor to control the transmission of light at each individual pixel
Active-matrix display
a mechanism that conveys the result of a computation to a user, such as a display, or to another computer
Output device
a mechanism through which the computer is fed information, such as a keyboard
Input device
a microprocessor containing multiple processors (“cores”) in a single integrated circuit
multicore microprocessor
a nonvolatile semiconductor
Flash memory
a portable language such as C, C++, Java or visual basic that is comprised of words and algebraic notation that can be translated by a compiler into assembly language
High-level programming language
a program that translates a symbolic version of instructions into the binary version
Assembler
a program that translates high-level language statements into assembly language
compiler
a small, fast memory that acts as a buffer for a slower, larger memory
Cache memory
a symbolic representation of machine instructions
Assembling language
Also called a called a chip. A device combining dozens to millions of transistors
Integrated circuit
also called a 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.
Central processor unit (CPU)
also memory built as an integrated circuit but faster and less dense than DRAM
Static random access memory (SRAM)
