technology allowing input of data from satellites.
clarity of images; resolution is a reference to the number of pixels, and a higher number of pixels (higher density) creates a clearer image).
size of monitor, indicated in inches (measured diagonally).
used for customizing Internet Web pages.
permanent or long-term storage of data outside the computer's CPU; referred to as nonvolatile because the contents are not erased when the computer power is turned off.
a subsection of a magnetic disk, used as part of the address to identify the location of stored data; a disk is divided into pie-shaped wedges, and an individual track within a wedge forms one sector.
a type of report in which only a part of the needed information can be predicted and designed in advance.
the originator of a message being communicated.
data is retrieved in serial order, or the order in which it was stored; data stored on magnetic tape must be retrieved or accessed sequentially.
use of one path to transmit bits of data.
execution of instructions one at a time; inefficient and no longer used, after being replaced by concurrent processing.
a communications channel over which data transmission travels in one direction only.
using multiple processors to provide the capability of processing more than one task at a given moment; multiprocessing and parallel processing are forms of simultaneous processing.
a card onto which data can be stored, allowing the card to be used for many purposes, such as for identification or for monetary transactions.
on-screen picture representing a specific function; selecting the picture activates the function (e.g., the user selects a printer icon to activate a printing activity).
concerns about the quality of human life.
instructions or programs for computer hardware.
Speech or voice recognition unit
technology that allows input to a computer system through use of the human voice.
software designed primarily for numeric activities and containing vertical columns and horizontal rows into which data is entered, somewhat like an accountant's worksheet.
upper-management decisions that involve long-range planning and consideration of external as well as internal factors.
a type of report that contains standard business information and can be designed in advance.
very high-capability, high-cost computer, used primarily for complex calculations such as those in research projects.
sequence of activities and groups involved in the overall process of delivering products and services to a customer.
transmission of a block of characters at a time rather than one character at a time.
related elements working together to achieve a goal.
software that serves as an intermediary between the hardware and the application software and people using the application software (e.g., by translating application commands into machine language and by providing on-screen information in a format that can be understood by humans).
