IT Vocab 3 Flashcards
A numbering system that uses sixteen digits, 0 through 9, and A through F
Hexadecimal system
A numbering system that uses ten digits, 0 through 9
Decimal System
An early computing machine that used punched cards and metal pins. It was used to compile the 1890 US Census
Hollerith’s Tabulating Machine
Information that a computer returns to a user such as images on a screen, sounds from speakers, and printed pages
Output
A discipline that is dedicated to meeting the computer needs of a business, schools, governments and other organizations
Information Technology
The study of computers and computing concepts. In practice, deals with creating software and using computers to solve problems
Computer science
The smallest unit of digital information, represented by a 1 or 0
Bit
A numbering system that uses two digits, 0 and 1.
Binary system
An international 16-bit encoding standard that accommodates character sets from multiple languages, with each letter, digit, or symbol being assigned a unique numeric value
Unicode
The fastest, most powerful computers that exist at a given time. These computers have processing capabilities designed to solve problems that are too complex for regular computers. They play vital roles in the advancement of national defense, science, and social change
Supercomputers
The saving of information on memory chips, discs, or other storage media by a computer for later use
Storage
A group of eight bits joined together
Byte
A physical signal, such as text, numbers, graphics, or sound, interpreted by converting it into binary numbers
Digital Data
A system for making digital resources publicly available over the internet using a web browser that paved the way for email, chatrooms, and social media sites
World Wide Web
Personal behavior that build responsibility and trust
Ethics
The representation of text by assigning a unique binary code to each character
Encoded text
A discipline that involves collecting and utilizing data to help organizations know what information they need, how to generate it, and how to turn it into meaningful decisions
Information systems
A mobile phone that functions as a computer and allows users to access the internet
Smartphone
The operations performed by a computer to retrieve, transform or classify information
Processing
The measurement in bytes of the volume that a storage device can contain
Storage space
a field of study that looks at how computers and other kinds of technology interact with humans
Human-computer interaction
The representation of integers using a group of bytes. Normally, one bit in one of the bytes represents the sign, 1 for negative and 0 for positive. The remaining 31 bits are used to encode the number itself using binary digits
Encoded integers
a smaller, faster, cheaper, and a more durable electronic device that replaced mechanical relays, which were slow and tended to wear down over time
transistor
Information that a user physically enters into a computer by pressing a key on a keyboard, clicking a mouse, tapping a touch screen, pushing a button on a game controller, speaking into a microphone, etc..
Input
An electronic device that allowed entire computers to be built into a single board, replacing modules for each part of the computer. Microchips paved the way for personal computer ownership
Microchip
Pronounced “ask-ee” and short for American Standard Code for Information Interchange, the most common format for text files in computers on the internet where each character is represented by a unique 7-bit binary code
ASCII
