Jhs 1 & 2 ICT Quiz

When files are deleted from a computer, they are not permanently removed from the system. Instead, they are moved to the Recycle Bin, which acts as a temporary storage for deleted files. The Recycle Bin allows users to easily restore deleted files if needed or permanently delete them from the system. Therefore, the correct answer is Recycle Bin.

Files are typically organized and stored in folders. Folders provide a way to group related files together and create a hierarchical structure for organizing and accessing files on a computer or storage system. Folders allow for better organization and easier navigation of files, making it easier to locate and manage specific files when needed.

The system unit is where the components that process data are located. This includes the CPU, memory, motherboard, and other internal components. The system unit is responsible for executing instructions, performing calculations, and managing data storage. Input devices, such as keyboards and mice, are used to input data into the system unit, while output devices, such as monitors and printers, are used to display or print the processed data. However, the actual processing of data occurs within the system unit itself.

A disk content that is recorded at the time of manufacture and that cannot be changed or erased by the user is referred to as read-only. This means that the user is only able to read the information on the disk but cannot modify or delete it. The content is permanently stored and cannot be altered, providing a level of security and protection for the data.

A CD-RW can be written to, meaning that data can be added, modified, or deleted from the disc multiple times. On the other hand, a CD-ROM can only be read from, meaning that it can only be used to retrieve data that has been previously written onto it. This fundamental difference in functionality is what sets them apart.

Text formatting refers to the process of adjusting the appearance of text on a page. It includes various elements such as font style, size, color, alignment, and spacing. Text formatting allows for the manipulation of text to enhance readability and convey meaning effectively. This term encompasses the overall visual presentation of words on a page, ensuring that they are visually appealing and easily comprehensible to the reader.

The subject line of an email describes the contents of the message. This line provides a brief summary or title of the email, giving the recipient an idea of what the email is about before they open it. The subject line helps the recipient prioritize and organize their emails, making it easier for them to find and respond to important messages.

Embedded computers are specially designed computer chips that reside inside other devices, such as your car or your electronic thermostat. These computers are built to perform specific tasks and are integrated into the device they are designed for. They are typically small in size, low in power consumption, and have limited capabilities compared to general-purpose computers. Embedded computers are commonly used in various industries, including automotive, healthcare, and consumer electronics, to provide dedicated functionality and control within the device they are embedded in.

A comprehensive software system that builds, maintains, and provides access to a database is known as a DBMS (Database Management System). This system is responsible for organizing and storing data efficiently, as well as handling tasks such as data retrieval, data manipulation, and data security. It acts as an interface between the users and the database, allowing them to interact with the data in a controlled and structured manner. Therefore, DBMS is the correct answer in this case.

The control unit is responsible for accessing and decoding program instructions in the CPU. It coordinates the flow of data among various system components, ensuring that instructions are executed in the correct order. The control unit acts as the "brain" of the CPU, managing the overall operation of the computer system. It communicates with other parts of the CPU, such as the ALU, to carry out instructions and perform calculations. The motherboard, ALU, and megahertz are not specifically responsible for accessing and decoding program instructions or coordinating data flow, making them incorrect choices.
