Operating System (OS) - ANSWER//Software used to control the computer and its
peripheral equipment.
Input Device - ANSWER//device used to insert data into a computer or other device (ex:
keyboard, mouse, microphone, scanner, voice recognition)
Output Device - ANSWER//device that projects images, gives sound, and basically
gives out the info from the computer so the user can obtain it (ex: monitor, printer,
projector, speakers)
Binary Code - ANSWER//Groupings of 1's and 0's that makes information that a
computer can understand.
Hardware - ANSWER//Physical elements of a computing systems (printer, circuit
boards, wires, keyboard, etc)
Machine Language - ANSWER//Programs written in binary code
High-level language - ANSWER//easier for humans to understand
Interpreter - ANSWER//translates source code into machine code one line at a time
Binary Number System - ANSWER//Base2
Decimal Number System - ANSWER//Base10
Octal Number System - ANSWER//Base8
Hexadecimal Number System - ANSWER//Base16
Hard Drive - ANSWER//Storage device that stores digitally encoded data on rapidly
rotating rigid disks with magnetic surfaces. The device is either permanently installed
within the computer case or can be portable
, Motherboard - ANSWER//Printed circuit board on which the CPU, RAM chips and other
electronic circuit elements of a digital computer are frequently located.
RAM - ANSWER//Random Access Memory - temporary place to store material that
works quickly. erased when computer turns off. Volatile.
Power Supply - ANSWER//A device that provides power to a computer.
Wireless Network - ANSWER//Any type of computer network that is not connected by
cables of any kind.
ROM - ANSWER//Read Only Memory-Data stored in ROM can only be modified slowly,
with difficulty, or not at all, so it is mainly used to store firmware
Firmware - ANSWER//permanent software programmed into a read-only memory.
algorithm - ANSWER//A list of steps to finish a task. A set of instructions performed with
or without a computer. For example, the collection of steps to make a peanut butter and
jelly sandwich is an algorithm.
analysis - ANSWER//process of automatically analyzing the behavior of computer
programs for things like correctness, robustness, or safety
bandwidth - ANSWER//a data transmission rate
BIOS - ANSWER//Basic Input Output System - special firmware stored in a chip on your
computer's motherboard. First program that runs every time you turn on computer.
bitmap - ANSWER//image represented as two-dimensional array of brightness values
for pixels
Boolean - ANSWER//of or relating to a combinatorial system devised by George Boole
that combines propositions with the logical operators AND and OR and IF THEN and
EXCEPT and NOT
cloaking - ANSWER//a technique to deliver content on a Web page to a search engine
in such a way that different content than what is delivered to a regular human user
appears on the search engine. Goal is to boost a website's search engine rank on
certain keywords
CMOS - ANSWER//short for Complementary Metal-Oxide Semiconductor; an on-board,
battery powered semiconductor chip inside computers that stores information. When
you make changes to your BIOS configuration, the settings are not stored on the BIOS
chip itself. Instead, they are stored on a CMOS.
