Chapter 2 Flashcards
All computers, including desktop and notebook microcomputers, midrange systems, mainframes, and supercomputers, are made up of the same six basic components. Which of the following lists is entirely made up of some of these basic components?
control unit, memory, and output
Which of the following is not an example of a computer output device?
MICR reader
Which method of input can recognize characters from typed, printed, or handwritten material?
OCR
Which of the following is not an advantage of secondary storage devices compared to main memory?
fast speed
DASD refers to:
direct access storage device.
Machine language is the form of a computer program that the control unit of the computer has been built to understand. In general, a machine language instruction consists of two parts, which are:
operation code and address(es).
Evaluating how well various computers will handle an organization’s workload by running a representative set of real jobs on the different machines is called:
benchmarking
Which type of computer is often used for numerically intensive scientific calculations or to act as an extremely large Web server?
supercomputers
Which type of computer serves as the heart of the computing systems for many, perhaps most, major corporations and government agencies? This type of computer system also can act as a large Web server, as a server in a client/server application, and has the widest range of available applications.
mainframes
Which of the following computer storage devices is not an example of a direct access storage device?
magnetic tape drive
In the 2000s, a new way of handling multiple servers in a computing center became popular, in which multiple server modules are housed in a single chassis, saving space in the computing center, reducing the required cabling, and improving system management. What are these servers called?
blade servers
Assembly language programs are converted to machine language using an assembler. The resulting machine language program is called a(n) ________ program.
A) source
object
The language translator program which translates an entire 3GL or 4GL program into machine language before any of the program is executed is called a(an):
compiler
What are the two major categories of computer software?
applications software and support software
Which of the following is an example of applications software?
inventory record-keeping programs
spreadsheet packages
word-processing software
The collection of applications programs commonly used by office workers–including word processing, spreadsheets, electronic mail, presentation graphics, and so on–are referred to as ________ software
personal productivity
Each response below lists two operating systems in common use today. In which response are both of the operating systems listed open systems?
Linux and UNIX
On large computers, the operating system switches back and forth among multiple programs stored in memory in order to overlap input and output operations with processing time; the purpose of this switching is to maximize the work done by the CPU. What is this concept of switching among multiple programs in memory called?
multiprogramming
The following are benefits associated with the procedural language COBOL
The language resembles English.
It is standardized.
It is relatively easy to learn.
HTML uses ________ placed within a document to tell the Web browser how to display various elements on a Web page.
tags
A 4 GL, nonprocedural language–often provided with the database management system–which is used to retrieve data from a database is called a ________ language.
query
Which of the following is an example of communications interface software that is used to transfer files from one computer system to another?
FTP
The CPU is made up of two components, the control unit and memory.
FALSE: It is made up of the control unit and the arithmetic/logic unit.
The stored-program concept allows users to specify a list of operations that can be carried out at electronic speeds, rather than waiting for the user to specify each operation separately.
TRUE
Encapsulation is one of the important features of objects (in object-oriented programming) in which a subclass inherits the properties, methods, and events of the class to which it belongs.
FALSE
Explanation: The statement above is the definition of inheritance, not encapsulation.
