Question 1

A bit that is turned off is represented by the value -1.

Accepted Answer

A bit that is turned off is represented by the value 0, not -1.

Question 2

Programs are commonly referred to as
A) system software
B) software
C) application software
D) utility programs

Accepted Answer

Programs are generally referred to as software, which encompasses both system software and application software.

Question 3

Which of the following is considered to be the world's first programmable electronic computer?
A) IBM
B) Dell
C) ENIAC
D) Gateway

Accepted Answer

ENIAC (Electronic Numerical Integrator And Computer) is considered to be the world's first programmable electronic computer, developed between 1943 and 1945 by John Mauchly and J. Presper Eckert at the University of Pennsylvania. IBM, Dell, and Gateway are all computer companies, but none of them developed the first programmable electronic computer.

Question 4

Which of the following is not a microprocessor manufacturing company?
A) Intel
B) Dell
C) AMD
D) Motorola

Accepted Answer

Dell is a computer manufacturing company, not a microprocessor manufacturing company. Intel, AMD, and Motorola are all companies that produce microprocessors.

Question 5

The CPU understands instructions written in a binary machine language.

Accepted Answer

The CPU only understands instructions written in machine language, which is represented in binary (0s and 1s).

Question 6

A software developer is the person with the training to design,create,and test computer programs.

Accepted Answer

A software developer is responsible for designing, creating, and testing computer programs. They typically have a strong background in programming, software engineering, and computer science.

Question 7

All programs are normally stored in ROM and are loaded into RAM as needed for processing.

Accepted Answer

Programs are typically stored in a storage medium, such as a hard drive or flash drive, rather than ROM. They are loaded from the storage medium into RAM for processing.

Question 8

RAM is a volatile memory used for temporary storage while a program is running.

Accepted Answer

RAM (Random Access Memory) is a volatile memory that holds data and instructions that are currently in use by the computer's programs and operating system. It is volatile which means that its content is lost when the power is turned off.

Question 9

Where does a computer store a program and the data that the program is working with while the program is running?
A) in main memory
B) in the CPU
C) in secondary storage
D) in the microprocessor

Accepted Answer

A computer stores both the program and the data that the program is working with in main memory (also known as RAM). The CPU retrieves instructions and data from main memory to execute the program. Secondary storage (such as hard drives or flash drives) is used for long-term storage of programs and data when they are not currently in use. The microprocessor is a component of the CPU and is not where programs or data are stored.

Question 10

The Python language uses a compiler which is a program that both translates and executes the instructions in a high-level language.

Accepted Answer

The Python language uses an interpreter, not a compiler, which executes the instructions in the high-level language directly without translating them into machine language first.

Question 11

The process known as the __________ cycle is used by the CPU to execute instructions in a program.
A) decode-fetch-execute
B) decode-execute-fetch
C) fetch-decode-execute
D) fetch-execute-decode

Accepted Answer

The fetch-decode-execute cycle is the correct order in which the CPU performs operations. First, it fetches the instruction from memory, then decodes the instruction to determine what action needs to be performed, and finally executes the instruction. This cycle repeats until the program is complete.

Question 12

The encoding technique used to store negative numbers in the computer's memory is called
A) Unicode
B) ASCII
C) floating-point notation
D) two's complement

Accepted Answer

The most commonly used method for storing negative numbers in memory is two's complement. This technique involves flipping all the bits of the positive number and adding 1 to the result. This results in a binary value that represents the negative number. Two's complement is preferred over other methods like sign-magnitude notation and ones' complement due to its simplicity and ease of implementation in hardware. Unicode and ASCII are encoding techniques used for representing characters, while floating-point notation is used for representing decimal numbers.

Question 13

Which language is referred to as a low-level language?
A) C++
B) Assembly language
C) Java
D) Python

Accepted Answer

Assembly language is considered a low-level language because it is closer to machine language and allows the programmer to directly manipulate the computer's hardware, unlike higher-level languages like C++, Java, and Python which are more abstract.

Question 14

The main reason to use secondary storage is to hold data for long periods of time,even when the power supply to the computer is turned off.

Accepted Answer

Secondary storage devices like hard drives, solid state drives, and flash drives are designed to store data for extended periods of time, even when the computer is turned off. This is in contrast to primary storage (RAM), which is volatile and only holds data while powered on.

Question 15

IDLE is an alternative method to using a text editor to write,execute,and test a Python program.

Accepted Answer

IDLE is an Integrated Development Environment (IDE) for Python which allows users to write, execute and test code without the need for a separate text editor.

Question 16

What type of volatile memory is usually used only for temporary storage while running a program?
A) ROM
B) TMM
C) RAM
D) TVM

Accepted Answer

RAM (Random Access Memory) is a type of volatile memory that is used for temporary storage while running a program. It allows the computer to quickly access data that is needed to perform tasks, but the data is lost when the computer is powered off or restarted. ROM (Read-Only Memory) is non-volatile memory that retains its data even when the computer is turned off, and is mainly used to store firmware or permanent system instructions. TMM and TVM are not commonly used memory acronyms, and are not relevant to this question.

Question 17

The instruction set for a microprocessor is unique and is typically understood only by the microprocessors of the same brand.

Accepted Answer

The instruction set for a microprocessor is specific to the brand and model of the microprocessor, and may not be compatible with other brands or models. Therefore, the instruction set for a microprocessor is unique and can only be interpreted by microprocessors of the same brand.

Question 18

The following is an example of an instruction written in which computer language?
10110000
A) Assembly language
B) Java
C) machine language
D) C#

Accepted Answer

The given instruction is written in machine language, which is the lowest-level programming language that directly communicates with the computer's hardware. It consists of binary code (0s and 1s) that represent the machine instructions for the processor to execute. Assembly language is a low-level language that translates directly into machine language, but it uses symbolic names instead of binary code for instructions and registers. Java and C# are high-level programming languages that require a compiler to translate into machine code.

Question 19

Which computer language uses short words known as mnemonics for writing programs?
A) Assembly
B) Java
C) Pascal
D) Visual Basic

Accepted Answer

Assembly language uses short words known as mnemonics to represent instructions, making it easier for programmers to write programs for specific hardware architectures.

Question 20

A computer is a single device that performs different types of tasks for its users.

Accepted Answer

The answer of A computer is a single device that...
