designed to help the user keep hard disk space clean and efficient.

DISK MANAGEMENT UTILITIES

How well did you know this?

Not at all

Perfectly

moves data around on the disk so that small empty spaces are eliminated and data and programs are relocated to better use the available space.

DEFRAGMENTER

These programs can also compress data to free up disk space, partition a disk so that the user has more control over where different types of information are stored, and clean up disks by eliminating unnecessary data and information.

DISK MANAGEMENT UTILITIES

serve to help the users back up their data.

BACKUP UTILITIES

The computer owner may not have a backup copy of illegally downloaded programs.

ILLEGAL OR PIRATE PROGRAMS

A better choice is to back up one’s data

EXTERNAL (REMOVABLE) HARD DRIVE ONLINE BACKUP LOCATION

computer programs that either blank the monitor screen or fill it with constantly moving images when the user is away from the computer but does not turn it (and the monitor) completely off.

SCREEN SAVERS

CRT

CATHODE RAY TUBE

sometimes do require users to log back into their computer to turn off the screen saver, and those do have a security function.

SCREEN SAVERS

activate automatically if the computer does not receive any input from the user for a preset time period.

SCREEN SAVERS

it compresses information in files to be archived and then stores them in a compressed form in some long-term storage device.

ARCHIVAL SOFTWARE

The compression can sharply reduce the size of a large file such that it can be made small enough to e-mail to another person or location.

ARCHIVAL SOFTWARE

These programs are used by program developers to support their programming work or to run their programs.

PROGRAMMING ENVIRONMENT SUPPORT

usage refers to a set of very specific rules about words, word usage, and word order in order of a computer language.

SYNTAX

must be exactly correct for a computer to correctly interpret the code and run the program. Problems with either the logic or syntax will cause the program to fail, or perform incorrectly.

SYNTAX

includes all the various programs people use to do work, process data, play games, communicate with others, and watch videos and multimedia programs on a computer.

APPLICATION SOFTWARE

written in a particular programming language. Then the program is “compiled” (or translated) into machine language so the computer can understand the instructions and execute the program.

APPLICATION PROGRAMS

The most useful program in application software packages

WORD PROCESSING PROGRAM

an interdisciplinary field primarily concerned with the analysis, collection, classification, manipulation, storage, retrieval, movement, dissemination, and use of information

INFORMATION SCIENCE

It is concerned with technologies, strategies, and methodologies for getting the right information to people when it is needed without people getting overwhelmed with irrelevant and unwanted information.

INFORMATICS SCIENCE

in information science analysis include optimality, performance, complexity, and structure.

KEY THEMES

may refer to almost any variable that is measured on a numerical scale, such as cost, time (e.g., time to answer patient call lights), workload, etc.

OPTIMALITY

is typically considered in the context of the average performance of the information system over a series of communication instances.

PERFORMANCE

is a reality with the enormous masses of data and information generated, collected, stored, and retrieved.

COMPLEXITY

means developing a system for ordering and cataloging the data and information, particularly in a database.

STRUCTURE

a means of communicating with the computer.

PROGRAMMING LANGUAGES

can understand is binary or machine language.

CPU

is the true language of the computer. Any program must be translated into machine language before the computer can execute it.

MACHINE LANGUAGE

consists only of the binary numbers 1 and 0, representing the ON and OFF electrical impulses. All data—numbers, letters, and symbols—are represented by combinations of binary digits.

MACHINE LANGUAGE

machine dependent, which means that each model of computer has its own unique machine language.

MACHINE LANGUAGES

far more like the English language, but it is still very close to machine language.

ASSEMBLER LANGUAGE

still used a great deal by system programmers and whenever application programmers wish to manipulate functions at the machine level.

ASSEMBLER LANGUAGE

include procedural languages and were the beginning of the second level in programming languages.

THIRD-GENERATION LANGUAGES

require the programmer to specify both what the computer is to do and the procedure for how to do it.

PROCEDURAL LANGUAGES

offers powerful tools to support database management systems; this is particularly useful in any setting in which many users have to access the same databases at the same time.

MASSACHUSETTS GENERAL HOSPITAL UTILITY MULTI-PROGRAMMING SYSTEM (MUMPS)

developed by Sun Microsystems to be a relatively simple language that would provide portability across differing computer platforms and the security needed for use on a huge, public network like the Internet.

JAVA

critical for any serious Web developer.

JAVA PROGRAMMING SKILLS

As the popularity of GUI technology grew, several languages were developed to facilitate program development in

GRAPHICS-BASED ENVIRONMENTS

These programs and their cousins marketed by other companies have been used for a variety of applications, especially those that allow users to interact with electronic companies through the Internet.

VISUAL PROGRAMMING LANGUAGES

Another way to categorize programs is whether they were designed to work sequentially or concurrently

CONCURRENT AND DISTRIBUTED LANGUAGES

year where dual-core processors became available

2000

Program languages designed to take advantage of multiple processors

CONCURRENT LANGUAGES

Closely associated with the need to run multiple parts of a program at the same time is the need to accommodate multiple users at the same time.

MULTITHREADING

specialized application programs that require more involvement of the user in directing the program to do the necessary work.

FOURTH-GENERATION LANGUAGES

a statistical analysis program, the user enters a command (from a menu of commands) that tells the computer to compute a chi-square statistic on a particular set of numbers provided to the program.

STATISTICAL PACKAGE FOR SOCIAL SCIENCES (SPSS))

An important Fourth-Generation language

STRUCTURES QUERY LANGUAGE (SQL)

language designed for management and query operations on a relational database. It does far more than simply allow users to query a database. It also supports data insert, data definition, database schema creation, update and delete, and data modification.

STRUCTURES QUERY LANGUAGE (SQL)

Fifth-generation or third-level languages are called

NATURAL LANGUAGAES

which any user could give understandable commands to the computer in his or her own word style and accent, is being performed at the beginning of the twenty-first century.

NATURAL LANGUAGE RECOGNITION

clearly in the future of personal computing. The great difficulty is, of course, how to reliably translate natural, spoken human language into a language the computer can understand.

NATURAL LANGUAGE SYSTEMS

whereby the grammar of each word in the sentence is analyzed. It attempts to recognize the action described and the object of the action.

SEMANTIC ANALYSIS

An exciting application of natural language processing

BIOMEDICAL TEXT MINING

Strictly speaking, text formatters are not true programming languages. They are used to format content, original text, for visual display in a system.

TEXT FORMATTING LANGUAGES

most famous text formatting languages

HYPERTEXT MARKUP LANGUAGE (HTML)

used to format text for the World Wide Web and is one of the older formatting languages.

HTML

The most common package sold with computers

STANDARD OFFICE PACKAGE

presented a challenge to the computer software industry. A program sold to one customer can be installed on a very large number of machines. This practice obviously seriously harms the profitability of software development.

PROTECTING OWNERSHIP RIGHTS IN SOFTWARE

a multipurpose program, designed to support many applications in hospitals and their associated clinics.

HOSPITAL INFORMATION SYSTEM (HIS)

systems that help with patient tracking,

ADMISSION DISCHARGE TRANSFER

software, supplies inventory systems through which nurses charge IVs, dressings, and other supplies used in patient care, and laboratory systems that are used to order laboratory tests and report the results.

MEDICATION ADMINISTRATION RECORD (MAR)
