IT 101 Chapter One – Flashcards

Knowing what computers can and can't do; how they can and can't benefit you; when you can solve a computer problem on your own or require assistance

Describes any technology that helps to produce, manipulate, store, communicate, and/or disseminate information

A programmable multiuse machine that accepts data--raw facts and figures--and processes, or manipulates, it into information we can use

Consists of electromagnetic devices and systems for communicating over long distances

Using a computer or some other information device, connected through a network, to access information and services from another computer or information device

A communications system connecting two or more computers; the Internet is the largest such network

Messages transmitted over a computer network, most often the Internet

The name given to online education programs

Computer depictions of humans

Medical care delivered via telecommunications

Automatic devices that perform fjunctions ordinarily performed by human beings

Something is created, simulated, or carried on by means of a computer or a computer network - but that it is almost real

Transferring data from a remote computer to one's own computer

Encompasses not only the online world and the internet in particular but also the whole wired and wireless world of communication in general

A worldwide computer network that connects hundreds of thousands of smaller networks. These networks link educational, commercial nonprofit, and military entities, as well as individuals

An interconnected system of the internet computers (servers) that support specifically formatted documents in multimedia form

High-capacity machines with thousands of processors that can perform more than several trillion calculations per second

Molecule-sized nanostructures are used to create tiny machines for holding data or performing tasks

Water or air cooled computers that cost $5000 - $5 million and vary in size from small, to medium, to large depending on their use

Has a display screen and a keyboard and can input and output data but cannot by itself process data

Expensive, powerful personal computers usually used for complex scientific, mathematical, and engineering calculations and for computer-aided design and computer-aided manufacturing

Cost $500 to over $5,000, can fit next to a desk or on a desktop or can be carried around

Connects usually by special cable, a group of desktop PCs and other devices, such as printers, in an office or a building

The original style of microcomputers who's case or main housing sits on a desk, with keyboard in front and monitor (screen) often on top

Microcomputers whose case sits as a "tower," often on the floor beside a desk, thus freeing up desk surface space

Lightweight portable computers with built-in monitor, keyboard, heart test drive, cd/dvd drive, battery, and AC adapter that can be plugged into an electrical outlet; they weigh anywhere from 1.8 to 12 pounds

Mini-notebooks low cost, lightweight, small computers with functions designed for basic tasks, such as web searching, email, and word processing

A combination of smartphone and laptop computer with wireless connections

Smaller than notebook and netbook computers but larger and more powerful than PDA's and cell phones. Multimedia devices for consumers and business professionals

Combine personal organization tools - schedule planners, address books, to-do list - with the ability in some cases to send email and faxes

Electronic devices that can download eBooks, digital versions of regular books, articles, and magazines from various suppliers

The tiny specialized microprocessor installed in "smart" appliances and automobiles

A server is a central computer that holds collections of data (databases) and programs for connecting or supplying services to PCs, work stations, and other devices, which are called clients. These clients are linked by a wired or wireless network.

Consists of the raw facts and figures that are processed into information

Data that has been summarized or otherwise manipulated for use in decision making

Consists of all the machinery and equipment in a computer system

Consist of all the electronic instructions that tell the computer how to perform a task

Whatever is put in to a computer system

The manipulation a computer does to transform data into information

The internal computer circuitry (chips) that temporarily holds data waiting to be processed

The device and media that store data or information permanently

Whatever is output from the computer system the results of processing, usually information

An input device that converts letters, numbers, and other characters into electrical signals readable by the processor

A nonkeyboard input device that is used to manipulate objects viewed on the computer display screen

The box that houses the processor chip, the memory chips, and the motherboard with power supply, as well as some secondary storage devices

A tiny piece of silicon that contains millions of miniature electronic circuits

Represent primary storage, or temporary storage; they hold data before processing and information after processing, before it is sent along to an output or storage device

The main circuit board in the computer

For expanding the PCs capabilities - which gave you places to plug an additional circuit

A storage device that stores billions of characters of data on a non removable disk latter

A storage device that uses laser technology to read data from optical disks

Consist of devices that translate information processed by the computer into a form that humans can understand

Any component or piece of equipment that expands a computer input, storage, and output capabilities

Converts the processors output information into a video signal that can be sent through a cable to the monitor

Enhances the computer sound generating capabilities by allowing sounds to be output through speakers

The display device that takes the electrical signals from the video card and forms an image using points of colored light on the screen

The devices. Play sound transmitted as electrical signals from the sound card

An output device that produces text and graphics on paper

A device that sends and receives beta over telephone lines, or wirelessly via a network, to and from computers

Helps the computer perform essential operating tasks and enables the application software to run

Enables you to perform specific tasks - solve problems, perform work, or entertain yourself

The master control program that runs the computer

A small device used as a gateway to transfer electrical signals along predetermined paths (circuts)

Entire collections of electrical circuits or pathways that are now etched on tiny squares (chips) of silicon half the size of your thumbnail

A natural elements found in sand. in pure form, it is the base material for computer processing devices

The communication of computers to one another by communication line in order to provide online information access and/or the sharing of peripheral devices

Two way communication; the user can respond to information he or she receives and modify what a computer

Technology that presents information in more than one medium - such as text, pictures, video, sound, and animation - in a single integrated communication

The combining of several industries through various devices that exchange data in the format used by computers

Instead of storing your software and or data on your own PC or your own companies computers, you store it on servers on the Internet

A set of moral values or principles that govern the conduct of an individual or group
