Question 1

Computer programmers often refer to memory addresses using hexadecimal notation.

Accepted Answer

True, hexadecimal notation is commonly used to represent memory addresses in computer programming. Hexadecimal notation uses a base of 16, which can represent values from 0 to 15 with digits 0-9 and letters A-F.

Question 2

Variable names may not begin with a digit,although usually they may contain digits.

Accepted Answer

Variable names in most programming languages cannot begin with a digit, although they may contain digits as part of the name. For example, "myVariable" is a valid name, but "1stVariable" is not.

Question 3

A magic number is a named constant whose meaning is not immediately apparent.

Accepted Answer

A magic number is an unnamed constant whose meaning is not immediately apparent, often hardcoded directly into the code without explanation.

Question 4

The language translation software that converts a programmer's statements to binary form is called a ____.
A) processor
B) compiler
C) translator
D) central processing unit

Accepted Answer

A compiler is specifically designed to translate high-level programming statements into machine-level code or binary form that a computer can understand and execute. A processor and a central processing unit are hardware components that execute instructions, whereas a translator is a more general term that can refer to any type of program or tool that translates one language to another.

Question 5

To use a computer program,you must first load it into the computer's ____.
A) memory
B) monitor
C) disk
D) software

Accepted Answer

Loading a program into the computer's memory, also known as Random Access Memory or RAM, allows the computer to execute the program's instructions. The disk is where programs are stored, but they must be loaded into memory to run. The monitor is the screen that displays the program once it's running. Software is a general term that encompasses programs, but it is not where the program is loaded.

Question 6

No matter which programming language a computer programmer uses,the language has rules governing its word usage and punctuation.

Accepted Answer

All programming languages have their own set of syntax rules that govern the way code is written and executed, including rules for word usage, punctuation, and overall syntax structure.

Question 7

____ are instruction sets written by programmers.
A) Tests
B) Outputs
C) Programs
D) Inputs

Accepted Answer

Programs are sets of instructions written by programmers to direct a computer to perform specific tasks. Tests are used to check if a program works correctly, outputs are data generated by a program, and inputs are data entered into a program by a user.

Question 8

A(n)____ is the sequence of steps necessary to solve any problem.
A) algorithm
B) pseudocode list
C) rhythm
D) problem statement

Accepted Answer

An algorithm is a sequence of steps that outlines how to solve a problem. It serves as a roadmap or set of instructions for finding a solution to a given problem. Pseudocode is a type of informal code that helps programmers develop an algorithm, but it is not the same as an algorithm itself. Rhythm refers to a strong, regular pattern of movement or sound, and has no relevance to problem-solving. A problem statement is a description of a problem or challenge that needs to be addressed, but it is not a sequence of steps for solving that problem.

Question 9

____ are the two major components of any computer system.
A) Input and output
B) Monitors and printers
C) Keyboards and mice
D) Hardware and software

Accepted Answer

Hardware and software are the two major components of any computer system. Hardware includes physical components such as the central processing unit (CPU), memory, storage devices, and input/output devices. Software includes programs and applications that instruct the hardware to perform specific tasks. Without both hardware and software, a computer system cannot function properly. Input devices like keyboards and mice, and output devices like monitors and printers are important components but fall under the hardware category.

Question 10

External storage is needed to run a program but it is volatile.

Accepted Answer

External storage, such as hard drives or USB drives, is non-volatile, meaning it retains data even when the power is turned off. Volatile storage, on the other hand, refers to temporary memory such as RAM.

Question 11

When you declare variables,you have the option of assigning initial values to them.

Accepted Answer

When declaring variables, you can choose to initialize them by assigning an initial value.

Question 12

Each programming language uses a piece of software to translate programming language statements into ____.
A) logic
B) syntax
C) object code
D) semantic code

Accepted Answer

The process of translating programming language statements into machine language is known as compilation, and the result of this process is object code, which can be executed by the computer. Therefore, the correct option is C. Logic and semantic code are related to the programming language itself, and syntax refers to the rules that dictate the structure and format of programming language statements.

Question 13

The ____ of a language are the rules that govern word usage and punctuation.
A) semantics
B) structure
C) syntax
D) logic

Accepted Answer

Syntax refers to the rules that govern the structure of sentences, including word order, punctuation, and grammatical structures. Semantics refers to the meanings of words and how they are used in sentences. Logic refers to the principles of reasoning and argumentation. Therefore, the best choice is syntax.

Question 14

In arithmetic statements,the rules of precedence can be overridden using parentheses.

Accepted Answer

The use of parentheses can change the order of operations in arithmetic statements, allowing for a different evaluation than following the rules of precedence alone.

Question 15

A program that is free of syntax errors will produce the correct results.

Accepted Answer

A program that is free of syntax errors may still produce incorrect results due to logical errors in the code or other factors such as incorrect input or incorrect implementation of algorithms. Syntax errors only indicate errors in the structure and formatting of the code.

Question 16

The programmer's job can be broken down into five development steps.

Accepted Answer

The number of development steps in a programmer's job can vary depending on the methodology or framework being used, such as Agile, Waterfall, or others. There is no universally fixed number of steps.

Question 17

____ comprises the programs you use to manage your computer,including operating systems such as Windows,Linux,or UNIX.
A) System software
B) Hardware
C) Application software
D) Processing software

Accepted Answer

System software includes operating systems, device drivers, utilities, and other programs that manage computer hardware and provide basic functionality for other software to run. Windows, Linux, and UNIX are all examples of operating systems included in system software.

Question 18

Word-processing programs,spreadsheets,payroll and inventory programs,and even games are considered to be ____.
A) application software
B) system software
C) low-level programming languages
D) high-level programming languages

Accepted Answer

Word-processing programs, spreadsheets, payroll and inventory programs, and even games are all examples of application software. System software, on the other hand, refers to programs that manage computer hardware and provide functionalities essential to the operation of a computer system. Low-level programming languages are used to write operating systems and device drivers, while high-level programming languages are used to develop application software.

Question 19

____ is the process of walking through a program's logic on paper before you actually write the program.
A) Bench-checking
B) Bench-testing
C) Desk-checking
D) Desk-testing

Accepted Answer

Desk-checking is the process of reviewing a program's logic on paper before actually writing the code. This is typically done to catch any errors or inefficiencies before the code is written and tested. Bench-checking and bench-testing both involve testing a program after it has been written, while desk-testing is not a commonly used term in programming.

Question 20

It is more common for uninitialized variables to have an a valid default value assigned to them,than it is for them to contain an unknown,or garbage value.

Accepted Answer

Uninitialized variables can contain unknown or garbage values if they are not explicitly initialized. It is good programming practice to assign a default value to all variables to avoid unpredictable behavior in the code.
