Information systems (clep)

word processor - electronic device or computer software application, that performs the task of composition, editing, formatting, and sometimes printing of documents. spread sheet - an interactive computer application program for organization, analysis and storage of data in tabular form presentation program - presentation program is a software package used to display information in the form of a slide show FTP(file transfer protocol) - standard network protocol used to transfer computer files from one host to another host over a TCP-based network, such as the Internet. EDI(electric data interchange) - an electronic communication method that provides standards for exchanging data via any electronic means software development methodology - a division of software development work into distinct phases (or stages) containing activities with the intent of better planning and management "batch" processing - processed when a certain amount if items is reached, or when a certain period has passed. real time processing - processed right away transaction processing - processed right away, can cancel unlike real time encryption - conversion of electronic data into another dorm, used for security purposes information system - an integrated set of components for collecting, storing, and processing data and for delivering information, knowledge, and digital products. professional support system - offer the facilities needed to perform tasks specific to a given profession. For example, automotive engineers use computer-aided engineering (CAE) software collaboration support system - the main objectives of collaboration systems are to facilitate communication and teamwork among the members of an organization and across organizations knowledge management system - provide a means to assemble and act on the knowledge accumulated throughout an organization processing - the thinking performed by the computer, the calculations, the comparisons and decisions. 1 byte= - 8 bits(256 possible combinations) 1 bit= - one one or off position unicode - uses 16 bits, for windows nt and recent browsers ASCII - code sets of 7, used in unix and DOS/windows-based computers parity - way for computer to check for errors, parity varies from even to odd. adding or subtracting a bit. CPU - central processing unit main memory - stores the commands the CPU executes and the results machine cycle - fetch, decode,execute,store. MHz - megahertz 1MHz=1 million cycles megabyte - 1000000 bytes GHz - gigahertz= 1billion cycles RAM - random access memory, what the computer uses as Main Memory. Memory speed measures the time it takes to move data in or out of memory WAN - wide area network, spans over a large geographical distance LAN - local area network, span as far as schools, residence.. etc operating system - a computer program that conducts the communication between the various pieces of hardware (like the motherboard with its processor, the video card, sound card, and printer) and the programs you are running. malware - what you need protection from, viruses, spam. etc modular programming - software design technique that emphasizes separating the functionality of a program into independent, interchangeable modules, such that each contains everything necessary to execute only one aspect of the desired functionality. database - a collection of data that you want to manage, rearrange, and add to later. flat database - earliest and simplest database (spread sheets) relational database - more advanced and efficient database
