ISYS 363 SFSU EXAM QUESTIONS & DETAILED ANSWERS
ALREADY GRADED A+
Alpha testing - CORRECT ANSWER >>>testing an incomplete or early version of the system
Beta testing - CORRECT ANSWER >>>testing a complete and stable system by end users
Artificial intelligence - CORRECT ANSWER >>>A field in which the computer system takes on
the characteristics of human intelligence ex. Neural Networks, Natural Language Processing
Batch Processing - CORRECT ANSWER >>>A form of data processing whereby business
transactions are accumulated over a period of time and pared for processing as a single unit or
batch
real time processing vs. Batch - CORRECT ANSWER >>>Batch processing requires separate
programs for input, process and output. An example is payroll and billing systems. In contrast,
real time data processing involves a continual input, process and output of data. Data must be
processed in a small time period (or near real time).
Best practices (in ERP software) - CORRECT ANSWER >>>The most efficient and effective ways to
complete a business process
Bit - CORRECT ANSWER >>>A bit is the basic unit of information in computing and digital
communications. A bit can have only one of two values: 0 or 1.
Byte - CORRECT ANSWER >>>8 bits that together represent a single character of data

,Bug, patch, update, upgrade (software)
- Why is software not error free - CORRECT ANSWER >>>Always going to be bugs even if they fix
some through software updates
Business Intelligence - CORRECT ANSWER >>>The process of gathering enough of the right
information in a timely manner and usable form and analyzing it to have a positive impact on
business strategy, tactics, or operations
Circuit Switched network - CORRECT ANSWER >>>A network that sets up a circuit between the
sender and receiver before any communications can occur; this circuit is maintained for the
duration of the communication and cannot be used to support any other communications until
the circuit is released and anew connection is set up
Client/Server Architecture - CORRECT ANSWER >>>an approach to computing wherein multiple
computer platforms are dedicated to special functions, such as a database management,
printing, communication, and program execution
Cloud Computing
Software as a Service (benefits/risk) - CORRECT ANSWER >>>- A computing environment where
software and storage are provided as an Internet service and are accessed with a Web browser
-(SaaS)
Competitive Advantage
(Porter's five forces model) - CORRECT ANSWER >>>A significant and ideally long-term benefit
to a company over its competition
Porter's five forces model - CORRECT ANSWER >>>1. Buyer power
2. supplier power
2|Page
, 3. threat of substitute products or services
4. threat of new entrants
5. rivalry among existing competitors
Computer based info systems - CORRECT ANSWER >>>A single set of hardware, software
databases, telecommunications, people, and procedures that are configured to collect,
manipulate, store, and process data into information
Computer Networks - CORRECT ANSWER >>>The communications media, devices, and software
needed to connect two or more computer systems or device
Computer Programs - CORRECT ANSWER >>>Sequences of instructions for the computer
Operating System - CORRECT ANSWER >>>- A set of computer programs that controls the
computer hardware and acts as an interface with applications
Applications - CORRECT ANSWER >>>-Application software (an application) is a set of computer
programs designed to permit the user to perform a group of coordinated functions, tasks, or
activities. Application software cannot run on itself but is dependent on system software to
execute.
Operating System vs Applications - CORRECT ANSWER >>>Application software is the software
that you install onto your Operating System
Computer Security - CORRECT ANSWER >>>security applied to computing devices such as
computers and smartphones, as well as computer networks such as private and public
networks, including the whole Internet.
