Miss Lewis's 6th Grade Computer Retake Test

The correct answer is "saves its pictures on its memory card." This statement accurately describes one of the main functions of a digital camera. When a picture is taken, it is stored and saved on the camera's memory card, allowing the user to view and transfer the images later. This is a common feature found in most digital cameras and is widely known and accepted by the public. The other options given in the question are incorrect and do not accurately describe a digital camera's function or public acceptance.

A reboot refers to the action of restarting a computer after it freezes. This process helps to resolve any issues or errors that may have caused the computer to freeze in the first place. By restarting the computer, it clears the system's memory and allows it to start fresh, often resolving the freezing problem.

The correct answer is "when you type in your name and password". This is because logging on typically requires entering a username (name) and password to access a system or platform securely. The other options mentioned, such as cutting down a tree to make paper or entering personal information like address and phone number, do not align with the concept of logging on.

A password is a secret code used to log on to a computer. It is a security measure that ensures only authorized individuals can access the computer and its contents. By requiring users to enter a password, the computer system can verify their identity and grant them access to their personal files, applications, and settings. This helps protect sensitive information and prevent unauthorized access to the computer system.

The correct answer is "a computer that stands upright." This answer is correct because a tower is a type of computer that is designed to be placed in a vertical position. It is a common form factor for desktop computers, where the main components such as the motherboard, CPU, and storage drives are housed in a tall, rectangular case that stands upright on a desk or floor. This distinguishes it from other types of computers such as laptops or all-in-one computers, which have different form factors and designs.

A workstation is a single computer. This means that it refers to a computer system that consists of a single unit, including the hardware components and software programs, designed to be used by a single user at a time. It is not a central computer that saves files and programs, nor does it refer to the name of items that can be added to a computer. Additionally, it is not a portable device that can store data files and be used on another computer.

The correct answer is "an international group of computer networks connected to each other". This answer accurately describes what the internet is - a global network of interconnected computers and networks that allows for the exchange of information and communication between users worldwide.

ROM stands for Read-Only Memory. It is a type of computer memory that retains its stored data even when the computer is powered off or restarted. Unlike random-access memory (RAM), which is volatile and loses its data when the computer is turned off, ROM is non-volatile and retains its data permanently. ROM is typically used to store firmware or software instructions that are essential for the computer's operation. Therefore, the correct answer is "the memory that is NOT lost when you turn off the computer."

The firmware is a type of software that is embedded in a device's hardware. It acts as a bridge between the hardware and software, facilitating communication and coordination between the two. It provides the necessary instructions and protocols for the hardware components to interact with the software and vice versa. This allows the hardware to function properly and enables the software to utilize the hardware resources effectively.

Peripheral devices are items that can be connected to a computer to enhance its functionality or provide additional features. Examples of peripheral devices include printers, scanners, keyboards, mice, and external storage devices. These devices are not part of the central processing unit (CPU) or the main computer system, but they can be added or connected to the computer to perform specific tasks or provide input/output capabilities.

Traffic refers to the amount of data that is being transmitted over a network at a given time. It includes all the data packets that are being sent and received by devices connected to the network. This can include various types of data such as text, images, videos, etc. Monitoring network traffic is important for managing and optimizing network performance, as well as identifying any potential issues or bottlenecks.

The correct answer is "the instructions that tell your computer what to do." This answer accurately describes software as the set of instructions that directs the computer's operations and enables it to perform specific tasks. Software includes programs, applications, and operating systems that are installed on a computer to provide functionality and allow users to interact with the hardware. It is distinct from hardware components or peripherals that can be added to a computer system.

The Dvorak keyboard is an alternate keyboard layout that was developed as an alternative to the traditional QWERTY layout. It was designed to increase typing efficiency and reduce finger movement by placing the most commonly used letters on the home row. However, despite its potential benefits, the Dvorak keyboard was never widely accepted by the public and remains a niche option for typists.

The internal hard drive is the main storage area on a computer, where data files and programs are saved. It is measured in gigabytes, indicating its storage capacity. This is different from the other options provided, which include the central computer that saves files and programs (which is not specific to the internal hard drive), the ability to carry data files to use on another computer, and items that can be added to the computer such as a printer or scanner.

Random access memory (RAM) is a type of computer memory that is used for temporary storage when you open software or run programs. It allows the computer to quickly access and store data that is actively being used. However, unlike permanent storage devices such as hard drives, RAM is volatile, meaning that its contents are erased when the computer is shut off. Therefore, it is not suitable for saving data files in a way that can be carried and used on another computer. Additionally, RAM is not a central computer or an external item that can be added to the computer.

A floppy disk is a portable storage device made of bendable metal that is used to save data files. It is designed to be easily carried and can be used in different computers for transferring or accessing the saved data.

A file server is the central computer that saves files and programs. This means that it acts as a central storage location for data files and software programs that can be accessed by multiple users on a network. It allows for easy sharing and collaboration of files and ensures that data is securely stored and backed up.

The Qwerty keyboard is a keyboard created to slow down typists so the keys wouldn't jam. This keyboard layout was designed in the 19th century for mechanical typewriters. The placement of keys was intentionally arranged to prevent commonly used letters from being close together, reducing the likelihood of jamming. While the Qwerty layout is still widely used today, its original purpose of preventing jamming is no longer relevant with modern computer keyboards.

The correct answer is "all of these" because hardware refers to all the physical components of a computer system that can be seen and touched. This includes devices like printers, keyboards, monitors, and all other visible parts of the computer.

The given correct answer is "all of these." This means that a network can refer to a group of computers connected together, a computer lab in our school, a situation where a class all share one printer, and a scenario where it allows computers to talk to each other, like email. In other words, a network can encompass all these different aspects and functionalities.

The homerow is the place where you rest your fingers while typing. It consists of the keys asdf jkl; on a QWERTY keyboard layout. These keys are strategically placed to provide a comfortable and efficient typing experience. Additionally, they are the least used keys of the alphabet, which can slow down typists who are not familiar with touch typing. Therefore, the correct answer is that the homerow includes all of these aspects.
