Question 1

In Phase 5 of the SDLC,if parts of the new system are introduced at different times,this is what type of system conversion plan?
A) parallel implementation
B) direct implementation
C) phased implementation
D) pilot implementation

Accepted Answer

Phased implementation involves introducing parts of the new system at different times. This approach allows for a gradual transition and reduces the risk of disrupting operations. Option A, parallel implementation, involves running the old and new systems simultaneously, which can be costly and time-consuming. Option B, direct implementation, involves immediately replacing the old system with the new one, which can be risky and may lead to disruptions. Option D, pilot implementation, involves introducing the new system in a limited area or group before implementing it company-wide, which is not the same as introducing parts of the system at different times.

Question 2

In structured programming,________ determine the logical sequence in which computer program instructions are executed.
A) prototypes
B) control structures
C) algorithms
D) program flowcharts

Accepted Answer

Control structures determine the logical sequence in which computer program instructions are executed. Prototypes describe the structure of a function or method, algorithms are step-by-step instructions for solving a problem, and program flowcharts are visual representations of the logical flow of a program. However, control structures are specifically designed to control the flow of program execution.

Question 3

A(n)________ is a formula or set of steps for solving a particular problem.
A) prototype
B) algorithm
C) hierarchy chart
D) flowchart

Accepted Answer

An algorithm is a set of steps or rules that are followed to complete a task or solve a problem. It is a precise and logical process that takes inputs and produces outputs. The other choices are not specific to problem-solving methods. A prototype is a preliminary model or sample. A hierarchy chart shows the relationships among different elements of a system. A flowchart is a visualization tool that shows the steps or processes in a sequence.

Question 4

When you are designing a program,a hierarchy chart shows ________.
A) the flow of logic in a program
B) which programmers are assigned to code various modules of the program
C) the overall purpose of the program and identifies the modules needed to achieve that purpose and the relationship among them
D) the flow of data through a program

Accepted Answer

A hierarchy chart shows the overall purpose of the program and identifies the modules needed to achieve that purpose and the relationship among them. It provides a visual representation of the organization and structure of the program, and helps in understanding how the different modules are related to each other. It does not show the flow of logic or data through the program, and does not assign programmers to code specific modules.

Question 5

An IF-THEN-ELSE structure is also known as a(n)________.
A) test structure
B) iterative structure
C) selection control structure
D) sequence control structure

Accepted Answer

The IF-THEN-ELSE structure is a selection control structure as it allows the program to make decisions based on whether certain conditions are true or false. It is commonly used in programming to determine which block of code should be executed based on a given condition being met or not.

Question 6

________ consists of translating the logic requirements from pseudocode or flowcharts into a programming language.
A) Structuring
B) Coding
C) Charting
D) Documenting

Accepted Answer

Coding involves the actual implementation of the logic requirements into a programming language. Pseudocode and flowcharts are just tools used to plan and design the program, but the actual coding is what turns those plans into a functioning program.

Question 7

Locating and removing all errors from a computer program is called ________.
A) desk-checking
B) debugging
C) real-world testing
D) syntax testing

Accepted Answer

Debugging is the process of finding and resolving errors in software programs.

Question 8

What is the first thing a programmer should consider when defining a problem?
A) study the feasibility of implementing the program
B) clarify program objectives and users
C) specify the input
D) document the analysis

Accepted Answer

Before starting to solve a problem, a programmer must be clear about the objectives of the program and the users. This will help to define the problem more accurately and create a solution that better meets the needs of the users. The other options (study feasibility, specify input, document analysis) are important steps in the problem-solving process, but they should come after defining the objectives and users.

Question 9

A ________ is a list of instructions that the computer must follow to process data into information.
A) system
B) prototype
C) program
D) flow diagram

Accepted Answer

A program is a set of instructions that tells the computer what to do. It is the fundamental component of software, and without it, the computer would not be able to process data and produce meaningful output. A system is a collection of subsystems or components that work together to achieve a common goal, while a prototype is an early version of a product or process that is used to test and refine it. A flow diagram is a visual representation of the steps involved in a process or system, and may be used to design or communicate how a program should work, but it is not the same as a program itself.

Question 10

Large programs are broken down into manageable pieces,or processing steps,that are made up of logically related program statements called ________.
A) algorithms
B) structures
C) modules
D) sections

Accepted Answer

Modules are commonly used to break down large programs into smaller, more manageable pieces. They are made up of program statements that are logically related and can be executed as a single unit. Algorithms are a set of steps used to solve a problem, structures are used to store and organize data, and sections is not a commonly used term in programming.

Question 11

In programming,the incorrect use of control structures causes ________.
A) logic errors
B) syntax errors
C) run-time errors
D) debug errors

Accepted Answer

Incorrect use of control structures can cause logic errors, where the program runs but does not produce the expected output. Syntax errors refer to errors in the code syntax and result in the program not being able to compile or run. Run-time errors refer to errors that occur while the program is running, such as a divide-by-zero error or accessing an invalid memory location. Debug errors are not a common term used in programming and do not accurately describe the type of error caused by incorrect use of control structures.

Question 12

Typographical errors and / or incorrect use of the programming language are referred to as ________.
A) logic errors
B) syntax errors
C) run-time errors
D) bugs

Accepted Answer

Syntax errors refer to errors that occur when the programmer uses incorrect syntax or structure in their code. This can include typos or using the wrong programming language constructs. Logic errors refer to errors in the program's logic, such as when the program runs but doesn't produce the expected output. Run-time errors refer to errors that occur during program execution, such as when a variable is assigned an invalid value. Bugs is a general term that can refer to any errors or issues in the program.

Question 13

Adjusting and improving the system by having system audits and periodic evaluations and making changes based on new conditions is called systems ________.
A) development
B) maintenance
C) analysis
D) design

Accepted Answer

Systems maintenance involves making modifications and improvements to an existing system to optimize its performance and ensure it remains up-to-date with changing conditions. System audits and periodic evaluations are key components of maintenance activities, as they allow for the identification of areas that require improvement and inform decision-making around necessary changes. Systems development refers to the creation of entirely new systems, while systems analysis involves the detailed study of an existing system to understand how it works and how it can be improved. Systems design involves the creation of plans for building new systems or modifying existing ones.

Question 14

Which of these is the first step in programming?
A) document the program
B) code the program
C) design the program
D) clarify / define the problem

Accepted Answer

The first step in programming is to clarify and define the problem that needs to be solved by the program. This involves understanding the problem requirements, constraints, and inputs/outputs that the program needs to handle. Only after a clear understanding of the problem is obtained, can one move on to designing and coding the program.

Question 15

Which of these would NOT appear as a symbol on a program flowchart?
A) data type
B) decision
C) input / output
D) process

Accepted Answer

Data type is not represented as a symbol on a program flowchart. It is a concept used in programming languages to define the type of data that can be stored in a variable or used as a parameter in a function. The symbols on a program flowchart are used to represent the different elements of a program, such as decision points, input/output operations, and processing steps.

Question 16

A narrative that uses normal human-language statements to describe the logic and processing flow of a program is called ________.
A) a hierarchy chart
B) a flowchart
C) pseudocode
D) a prototype

Accepted Answer

Pseudocode is a method of representing a program's logic and processing flow using plain language statements that can be easily understood by humans. It serves as an intermediate step between the initial problem statement and the actual code implementation. Hierarchy charts and flowcharts are graphical representations of a program's processing flow, while a prototype is a preliminary version of a program or product. However, none of these directly use plain language statements to describe the logic and flow of the program. Therefore, the best choice in this case is C) pseudocode.

Question 17

All these are control structures used in structured programming EXCEPT ________.
A) iteration
B) selection
C) sequence
D) stop

Accepted Answer

"Stop" is not a control structure used in structured programming. The three main control structures are iteration (loops), selection (if-else statements), and sequence (executing instructions in order).

Question 18

________ involves reading a program to make sure that it is error-free and that the logic works.
A) Desk checking
B) Debugging
C) Beta testing
D) Compiling

Accepted Answer

Desk checking involves manually reviewing a program's code to detect any errors or logical flaws before it is compiled or run. Debugging involves identifying and correcting errors in a program after it has been tested. Beta testing involves releasing a program to a group of users for testing and feedback. Compiling involves translating source code into machine code that can be executed by a computer.

Question 19

The connector on a flowchart that shows movement to or from another part of the program and connects one symbol to another is represented by the ________ symbol.
A) circle
B) square
C) diamond
D) arrow

Accepted Answer

The circle symbol is used as a connector in flowcharts to show movement to or from another part of the program, connecting one symbol to another.

Question 20

A programmer must follow the rules for coding a particular programming language.These rules are called ________.
A) pseudocode
B) iteration
C) syntax
D) documentation

Accepted Answer

Syntax refers to the rules and structure of a programming language that a programmer must follow in order to write correct code. Pseudocode is a type of informal language used to plan out algorithms before writing actual code. Iteration refers to the process of repeating a set of instructions, often in a loop. Documentation refers to the written explanation of a program's code and functionality.
