Question 1

The basic commands that a computer performs are ____,and performance of arithmetic and logical operations.
A) input, file, list
B) output, folder, storage
C) input, output, storage
D) storage, directory, log

Accepted Answer

The basic commands that a computer performs are input, output, and storage. Input refers to data or commands being entered into the computer, output refers to data or results being displayed or produced by the computer, and storage refers to the computer's ability to store and retrieve data. Additionally, computers perform arithmetic and logical operations as part of their basic functionality. Options A, B, and D do not accurately represent these basic commands.

Question 2

The devices that the computer uses to display results are called ____ devices.
A) exit
B) entry
C) output
D) input

Accepted Answer

Output devices are used to display the results generated by the computer. Exit refers to leaving a program or shut down, entry refers to inputting data into the computer, and input devices are used to input data into the computer.

Question 3

The device that stores information permanently (unless the device becomes unusable or you change the information by rewriting it)is called primary storage.

Accepted Answer

The device that stores information permanently is called secondary storage, not primary storage. Primary storage refers to the temporary storage area that holds data and instructions while the computer is running.

Question 4

To develop a program to solve a problem,you start by analyzing the problem.

Accepted Answer

It is necessary to analyze the problem before developing a program, in order to understand the requirements and constraints of the problem and determine the best approach for solving it.

Question 5

Several categories of computers exist,such as ____.
A) microframe, midframe, and miniframe
B) midsize, microframe, and mainframe
C) mainsize, midsize, and microsize
D) mainframe, midsize, and micro

Accepted Answer

The three categories of computers are indeed mainframe, midsize, and micro, as they each represent different sizes and capacities of computing power. A micro computer is a small, typically personal computer designed for individual use, while a midsize computer is larger and meant for more industrial or commercial applications. A mainframe computer is even larger still, designed for heavy-duty computing tasks and able to handle vast amounts of data and users simultaneously.

Question 6

The ____ is the brain of the computer and the single most expensive piece of hardware in your personal computer.
A) MM
B) ROM
C) RAM
D) CPU

Accepted Answer

The CPU (Central Processing Unit) is the brain of the computer and is responsible for executing instructions. It is also the most expensive piece of hardware in a personal computer. MM (Memory Module) refers to the physical memory modules that are inserted into the motherboard to provide additional memory. ROM (Read-Only Memory) refers to a type of memory that is non-volatile and typically used for storing the computer's BIOS. RAM (Random Access Memory) is a type of volatile memory used by the CPU to temporarily store data and instructions during operation.

Question 7

Main memory is an ordered sequence of items,called ____.
A) pixels
B) registers
C) memory cells
D) addresses

Accepted Answer

Memory cells are the units of storage in main memory. Pixels are units of display on a screen and registers are small bits of memory within the CPU. Addresses are used to locate memory cells, but they are not themselves items in main memory.

Question 8

When the power is switched off,everything in ____ is lost.
A) main memory
B) secondary storage
C) hard disks
D) floppy disks

Accepted Answer

When the power is switched off, everything in the main memory is lost. Main memory, also known as RAM (Random Access Memory), is a volatile storage device that stores data temporarily while a program is running. Once the power is turned off, the data is lost because it was not saved to a non-volatile storage device like a hard disk or a solid-state drive. Secondary storage devices like hard disks and floppy disks are non-volatile and can retain data even when the power is turned off.

Question 9

When you compile your program,the compiler identifies the logic errors and suggests how to correct them.

Accepted Answer

The compiler can identify syntax errors (incorrect use of programming language elements), but not logic errors (errors in the design or logic of the program). It is up to the programmer to identify and correct logic errors.

Question 10

The devices that feed data and programs into computers are called output devices.

Accepted Answer

Output devices are devices that receive data and information from computers, whereas input devices are devices that feed data and programs into computers.

Question 11

Main memory is directly connected to the CPU.

Accepted Answer

Main memory, also known as RAM, is directly connected to the CPU through a memory bus (or system bus) in order to provide fast access to data and instructions.

Question 12

The command that does the linking on Visual C++ 2010 Express and Visual Studio 2010 is Make or Remake.

Accepted Answer

The command that does the linking on Visual C++ 2010 Express and Visual Studio 2010 is actually "Link". "Make" and "Remake" are not valid commands for linking.

Question 13

____ programs perform a specific task.
A) Application
B) System
C) Operating
D) Service

Accepted Answer

Application programs are designed to perform specific tasks such as word processing, creating presentations, editing photos, or browsing the internet. System programs, on the other hand, are designed to manage and control the hardware and software resources of the computer system. Operating systems (C) are a type of system program, while services (D) are specialized programs that provide specific functionality to other programs or users.

Question 14

The devices that feed data and programs into computers are called ____ devices.
A) entry
B) input
C) output
D) secondary

Accepted Answer

Input devices are used to feed data and instructions into a computer for processing. Examples of input devices include keyboards, mice, scanners, and cameras.

Question 15

When the computer is turned off,everything in secondary memory is lost.

Accepted Answer

Secondary memory (such as hard drives and solid-state drives) is non-volatile memory, which means that it retains data even when the computer is turned off. Primary memory (such as RAM) is volatile memory and loses its data when the computer is turned off.

Question 16

Information stored in main memory must be transferred to some other device for permanent storage.

Accepted Answer

Main memory is volatile, meaning it loses its contents when power is turned off or in case of a crash. Therefore, any important or permanent data needs to be transferred to nonvolatile storage, such as hard disk drives, solid-state drives, or optical disks.

Question 17

The basic commands that a computer performs are input (get data),output (display result),storage,and performance of arithmetic and logical operations.

Accepted Answer

This statement is true. Input involves getting data from a user or another device, output involves displaying results to the user, storage involves saving data to a device, and arithmetic and logical operations involve calculating and manipulating data. These are the basic commands that computers perform.

Question 18

Main memory is called ____.
A) read only memory
B) random access memory
C) read and write memory
D) random read only memory

Accepted Answer

Main memory is also known as random access memory (RAM), which allows quick access to data stored within the computer for processing. The other options are not accurate descriptions of main memory.

Question 19

The ____ monitors the overall activity of the computer and provides services.
A) central processing unit
B) operating system
C) arithmetic logic unit
D) control unit

Accepted Answer

The operating system is responsible for managing the overall activity of the computer and providing services to applications and users. The CPU (central processing unit) consists of the arithmetic logic unit and control unit, which are responsible for executing instructions and managing the flow of data within the computer, but do not provide services to applications or users directly.

Question 20

C++ programs have always been portable from one compiler to another.

Accepted Answer

C++ programs may not be portable from one compiler to another due to differences in implementation of the language and libraries used by the compilers.
