Arkansas Computer Business Applications- Unit 1 Test

Explanation
The mouse is considered an input device because it allows the user to input commands and interact with the computer. It is used to move the cursor on the computer screen and select objects by clicking. The mouse sends signals to the computer, which then processes the input and performs the desired actions. Unlike the computer screen and printer, which are output devices, the mouse is specifically designed for input purposes, making it the correct answer in this context.

Explanation
The system unit is the correct answer because it refers to the main enclosure of a computer that houses the CPU, power supply, memory, and storage. It is responsible for housing and protecting the internal components of a computer and providing the necessary connections for them to function together. The operating system is a software that manages computer hardware and software resources, while the CPU is the central processing unit responsible for executing instructions and performing calculations.

Explanation
The given correct answer is "File type". This refers to the extension at the end of a file name, which indicates the application that was used to create the document. For example, a file with the extension ".doc" indicates that it was created using Microsoft Word, while a file with the extension ".xls" indicates that it was created using Microsoft Excel. The file type is important for identifying the appropriate application to open and work with the file.

Explanation
The given correct answer is application software because it refers to computer software that is designed to perform specific tasks or jobs for the user. Examples of application software include word processors, spreadsheets, databases, and graphics software. Operating systems and system software, on the other hand, are responsible for managing and controlling the computer's hardware and providing a platform for other software to run on.

Explanation
The given answer, "System software," is correct because it accurately describes the type of software responsible for the general operation of a computer system. System software includes the operating software, which controls the hardware and manages the resources of the computer, as well as utility software that assists in system maintenance and file management. It is different from application software, which is designed to perform specific tasks for the user.

Explanation
The given correct answer, "File management," accurately describes the program on a computer that allows the user to perform various tasks related to files, folders, and the file system. This program enables the user to create, edit, view, print, rename, copy, or delete files and folders, as well as manage the entire file system.

Explanation
A storage device refers to external hardware used to store and retrieve data. This includes devices such as disk drives, CD/DVD drives, flash drives, or tape drives. These devices are used to store data for later retrieval and are considered peripheral devices as they are not directly involved in the processing of data.

Explanation
The Central Processing Unit (CPU) is responsible for executing commands from both the computer's hardware and software. It is the principal computer chip that contains several processing components, which ultimately determine the computer's operating speed. Often referred to as the "brain" of a computer, the CPU plays a crucial role in processing and executing instructions, making it an essential component of any computer system.

Explanation
The given correct answer is "Input device" because it accurately describes the devices that are used to enter data into a computer. Input devices such as keyboards, microphones, scanners, flash drives, and mice allow users to input data or commands into the computer system. These devices enable the computer to receive and process information, making them essential for data entry and interaction with the computer.

Explanation
The feature "Save as" allows the user to change the attributes of a file, such as its location, file name, or file type, before saving it. This feature is useful when the user wants to create a new version of the file with different attributes without altering the original file. By selecting "Save as," the user can specify the desired changes and save the file with the new attributes.

Explanation
The term "logon" refers to the action of gaining access to a computer or a network by entering a username and password. It is commonly used interchangeably with "login" or "sign in." This process verifies the user's identity and allows them to access the system or network. The other options, "file" and "save," do not accurately describe the action of entering a username and password to gain access.

Explanation
The term "save" refers to the action of preserving data or information for future use. It typically involves storing the data in a file or a specific location so that it can be accessed and retrieved at a later time. This can be done in various ways such as saving a document, saving changes to a file, or saving data in a database. The term "store" can also be used interchangeably with "save" in this context, as they both imply the act of preserving data for later use.

Explanation
An output device is a device that allows the user to view or listen to the data that a computer processes. This includes devices such as a monitor, printer, headphones, or speakers. These devices receive information from the computer and present it in a format that can be easily understood by the user. Therefore, the correct answer is output device.

Explanation
The correct answer is "Memory" because computer chips that store data and programs while the computer is working are commonly referred to as RAM or Random Access Memory. This type of memory is volatile, meaning it loses its stored information when the power is turned off. Memory is crucial for the functioning of a computer as it allows for the quick access and retrieval of data and programs while the system is running.

Explanation
The operating system is a type of system software that acts as a "go-between" for computer hardware and other software. It provides a platform for different software applications to run on the computer and manages the resources of the system. The operating system handles tasks such as memory management, file management, device management, and scheduling processes. It also provides a user interface for interacting with the computer. In summary, the operating system facilitates communication and coordination between the hardware and software components of a computer system.

Explanation
The term "peripheral" refers to any additional hardware that is not essential for a computer to function, but enhances its capabilities. Examples of peripherals include scanners, webcams, and computer joysticks. These devices can be connected to a computer to provide input, output, or both, depending on their functionality. Therefore, the correct answer for this question is "Peripheral."
