Unit 2 Flashcards
Computers have led to a third revolution for civilization, with the blank taking its place alongside the agricultural and the industrial revolutions.
information revolution
A computer designed for use by an individual, usually incorporating a graphics display, a keyboard, and a mouse.
Personal computer (PC)
A computer used for running larger programs for multiple users, often simultaneously, and typically accessed only via a network.
Server
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 computer inside another device used for running one predetermined application or collection of software.
Embedded computer
Many embedded processors are designed using blank, a version of a processor written in a hardware description language, such as Verilog or VHDL
processor cores
Blank are small wireless devices to connect to the Internet; they rely on batteries for power, and software is installed by downloading apps. Conventional examples are smart phones and tablets.
Personal mobile devices (PMDs)
Blank refers to large collections of servers that provide services over the Internet; some providers rent dynamically varying numbers of servers as a utility.
Cloud computing
Taking over from the conventional server is Cloud Computing, which relies upon giant datacenters that are now known as blank
Warehouse Scale Computers (WSCs)
Blank delivers software and data as a service over the Internet, usually via a thin program such as a browser that runs on local client devices, instead of binary code that must be installed, and runs wholly on that device. Examples include web search and social networking.
Software as a Service (SaaS)
A microprocessor containing multiple processors (“cores”) in a single integrated circuit.
Multicore microprocessor
Originally 1,099,511,627,776 (2^40) bytes, although communications and secondary storage systems developers started using the term to mean 1,000,000,000,000 (10^12) bytes
Terabyte (TB)
To reduce confusion, we now use the term blank for 2^40 bytes, defining terabyte (TB) to mean 10^12 bytes.
