Explanation:
A plotter is the best printer for printing large drawings such as architectural blueprints because it uses pens to draw continuous lines, allowing for precise and accurate printing of detailed designs. Unlike other printers, a plotter can handle large paper sizes and produce high-quality prints with sharp lines and fine details, making it the ideal choice for printing large-scale technical drawings.
Explanation:
UNIX is the correct answer because it is an operating system that is commonly used on mainframe computers. Mainframes are large, powerful computers that are used by organizations for critical applications and large-scale data processing. UNIX is known for its stability, security, and scalability, making it a popular choice for mainframe systems. It provides robust features and capabilities that are necessary for handling the complex and demanding requirements of mainframe computing.
Explanation:
When you type a character on your keyboard while working with a spreadsheet program, the operating system is the first to be notified that a key has been pressed. It then passes this information to the spreadsheet program. This allows the program to register the keystroke and perform the appropriate action, such as entering data into a cell or executing a command. The operating system acts as an intermediary between the keyboard input and the spreadsheet program, facilitating communication between the two.
Explanation:
Mozilla Firefox is a web browser, not an email program. While it does have some email capabilities, such as the ability to access webmail services, it is primarily used for browsing the internet and does not have the full range of features that dedicated email programs like Microsoft Outlook, Eudora, and Lotus CC have.

Explanation:
A spreadsheet program is best suited for performing calculations and analyzing data because it allows users to organize data in rows and columns, perform mathematical calculations, create formulas, and generate graphs and charts. It provides a structured and efficient way to input, manipulate, and analyze numerical data, making it ideal for tasks such as budgeting, financial analysis, and data analysis. Word processing programs are more focused on creating and editing text documents, while database programs are designed for storing and managing large amounts of data. Presentation programs are used for creating slideshows and visual presentations.
Explanation:
The correct answer is DOS because the picture likely shows the command prompt interface of the DOS operating system. DOS, which stands for Disk Operating System, was a popular operating system in the early days of personal computers. It featured a command-line interface where users could enter commands to perform tasks. The picture may show the characteristic black screen with white or green text that was common in DOS.

To find the size of a folder, you can display the folder's properties. This will provide information about the folder, including its size. By right-clicking on the folder and selecting "Properties," a window will open displaying various details about the folder, such as the size in bytes or kilobytes. This method allows you to easily determine the size of a folder without having to open it or change any view settings.
Explanation:
Airline ticket reservation systems typically handle a large volume of transactions and require significant processing power, storage, and network capabilities. These systems manage bookings, seat availability, flight schedules, passenger information, and other critical data for multiple flights and airlines. Due to the scale and complexity of these operations, a mainframe or a robust server infrastructure is often used to support the demands of the airline industry. This allows for efficient processing, reliability, and the ability to handle concurrent requests from various users and locations.
Explanation:

Explanation:
When you buy a new computer, it is most likely pre-installed with the operating system. The operating system is the software that manages the computer's hardware and software resources, allowing other programs to run on the computer. It provides a user interface and enables the user to interact with the computer. Without an operating system, the computer would not be able to function properly and other programs like a database program, accounting program, or spreadsheet program would not be able to run. Therefore, the operating system is an essential component that is typically pre-installed on a new computer.
