Question 1

In ____ language, if we insert or delete an instruction, all memory addresses following that instruction will change.
A) assembly
B) machine
C) low-level programming
D) high-level programming

Accepted Answer

In machine language, if we insert or delete an instruction, all memory addresses following that instruction will change because machine language instructions are directly executed by the CPU and any change in the instruction sequence will affect the subsequent memory addresses.

Question 2

The conversion of symbolic op codes such as LOAD, ADD, and SUBTRACT to binary makes use of a structure called the ____.
A) op code table
B) assembler
C) loader
D) library

Accepted Answer

The conversion of symbolic op codes to binary is usually done through an op code table, which lists each opcode and its corresponding binary code. The assembler reads this table and converts each symbolic opcode to its binary equivalent during the assembly process. The other options mentioned (loader and library) are not directly involved in the conversion of op codes to binary.

Question 3

A(n) ____ operation involves the comparison of values and the subsequent use of the outcome to decide what to do next.
A) iterative
B) conditional
C) sequential
D) transformer

Accepted Answer

A conditional operation involves the comparison of values and making a decision based on the outcome. Iterative operations involve repeating a set of instructions multiple times, sequential operations involve executing instructions in a linear order, and transformer operations involve changing or manipulating values in some way.

Question 4

____ operation codes are restricted to be used in the operating system or other system software.
A) Privileged
B) User
C) Specialized
D) System

Accepted Answer

Privileged operation codes are only accessible to the operating system or other system software, whereas user-level operation codes are available to application programs. Specialized and system operation codes are not widely recognized terms in computer science.

Question 5

The set of services and resources created by the system software and seen by the user is called a(n) ____ machine.
A) naked
B) virtual
C) assembler
D) Von Neumann

Accepted Answer

A virtual machine provides an interface to the user that abstracts the underlying hardware and system software, making it appear as though the user is interacting with a completely independent system.

Question 6

After all the fields of an assembly language instruction have been translated into binary, the newly built machine language instruction and the address of where it is to be loaded are written out to a file called the ____ file.
A) table
B) source
C) data
D) object

Accepted Answer

The newly built machine language instruction and the address of where it is to be loaded are written out to a file called the object file. This file contains the binary code and linking information that can be loaded into memory and executed by the computer. The other options mentioned (table, source, and data) do not accurately describe the purpose or content of this file.

Question 7

A program written in assembly language is called the ____ program.
A) virtual
B) object
C) data
D) source

Accepted Answer

A program written in assembly language is referred to as the source program. This is because it is the original code written by the programmer, which will later be translated into machine code by an assembler.

Question 8

A(n) ____ invokes a service of the assembler.
A) compiler
B) pseudo-op
C) loader
D) operation

Accepted Answer

Pseudo-ops are instructions in assembly language that direct the assembler to perform certain tasks, such as defining variables and setting program attributes. They do not correspond to machine instructions, but rather invoke services of the assembler. Therefore, a pseudo-op fits the given definition.

The other choices do not fit the definition. A compiler generates executable code from source code, but it is not a service of the assembler. A loader loads executable code into memory for execution, but it does not invoke services of the assembler. An operation is a fundamental instruction that can be executed by a processor, but it is not a service of the assembler.

Question 9

A machine language program is called the ____ program.
A) source
B) object
C) data
D) virtual

Accepted Answer

A machine language program is converted to object code, which is the binary representation of the machine language instructions, before it can be executed by the computer. Therefore, the program in machine language is called the object program.

Question 10

____, such as text editors, are sometimes organized into collections called program libraries.
A) Programming tools
B) Office tools
C) Packages
D) Utilities

Accepted Answer

The answer of ____, such as text editors, are sometimes...

Question 11

System software acts as a(n) ____ between the users and the hardware.
A) translator
B) intermediary
C) tester
D) security agent

Accepted Answer

System software acts as an intermediary between the users and the hardware, translating the user's commands into a language that the hardware understands and vice versa. It also provides a platform for other software applications to run on top of. System software is responsible for managing and controlling the hardware, providing essential services like memory management, device drivers, and security.

Question 12

Icons displayed on the screen are selected with a mouse and a button using a technique called ____.
A) windows interface
B) point-and-click
C) panel interface
D) command line

Accepted Answer

Point-and-click is the technique used to select icons displayed on the screen with a mouse and a button. The other options listed are not specific to this action.

Question 13

Translators for ____ are called compilers.
A) assembly language
B) machine language
C) low-level languages
D) high-level languages

Accepted Answer

Translators for high-level languages are called compilers. High-level languages are usually written in a way that is easier for humans to read and write, while still being able to be translated into machine code that computers can understand. Examples of high-level languages include Java, Python, and C++.

Question 14

A ____-generation operating system will typically be a parallel processing operating system that can efficiently manage computer systems containing tens, hundreds, or even thousands of processors.
A) second
B) third
C) fourth
D) fifth

Accepted Answer

Fifth-generation operating systems are designed to efficiently manage parallel processing and the complexities of computer systems with a large number of processors, aligning with the advancements in computing technology and the need for handling extensive computational tasks simultaneously.

Question 15

In assembly language, a(n) ____ is a name, followed by a colon, placed at the beginning of an instruction.
A) op code mnemonic
B) comment
C) address field
D) label

Accepted Answer

A label is a name followed by a colon, used in assembly language to mark a location in memory or a target within the code for branching or jumping instructions. It is not an op code mnemonic, a comment or an address field.

Question 16

The ____ problem-solving cycle involves inputting code to an assembler, translating it to machine language, loading it into a Von Neumann computer, and executing to produce answers to the problem.
A) Von Neumann
B) modern
C) algorithmic
D) conditional

Accepted Answer

The answer of The ____ problem-solving cycle involves inputting code...

Question 17

The ____ hides from the user the messy details of underlying hardware.
A) interface
B) operating system
C) system software
D) machine code

Accepted Answer

An interface is a layer between the user and the underlying hardware, which allows the user to interact with the hardware without needing to understand the underlying details. The interface abstracts away the complexity of the hardware, presenting a simpler and more user-friendly interface. This can include graphical user interfaces (GUIs), command-line interfaces (CLIs), or application programming interfaces (APIs). The other options (operating system, system software, and machine code) may also play a role in hiding details of the hardware, but interface is the most general and encompassing term.

Question 18

C++ and Java are examples of ____ languages.
A) low-level programming
B) high-level programming
C) machine
D) assembly

Accepted Answer

C++ and Java are both high-level programming languages, meaning they have a higher level of abstraction from machine language and are designed to be easier for humans to write and understand code in. Low-level programming languages like machine language and assembly are closer to the machine's language and are more difficult to read and write.

Question 19

A Von Neumann computer without any helpful user-oriented features is called a(n) ____ machine.
