Q & A

What is the main topic of today's lesson?

The main topic of the lesson is about 'Peripheral Input and Output Devices,' specifically focusing on output devices such as printers and scanners.

Why is it important to share tasks and materials in the group?

It is important to share tasks and materials in the group to ensure everyone stays informed and can participate in the learning process. Sharing also promotes collaboration and accountability among students.

What are the different types of printers mentioned in the script?

The script mentions three types of printers: dot-matrix, inkjet, and laser jet printers.

How has printer connectivity evolved over time?

Printer connectivity has evolved from using parallel ports to USB ports. The latest printers now mostly use USB connections, replacing the older parallel port systems.

What is the function of a printer?

A printer is an output device that is used to print documents and images that are created on a computer or laptop.

What are the key differences between dot-matrix, inkjet, and laser jet printers?

Dot-matrix printers use impact printing to create dots on paper, inkjet printers use liquid ink sprayed onto the paper, and laser jet printers use a laser to form text and images by fusing toner to paper.

How do you install a printer to a computer?

To install a printer, first connect the printer's cable (either parallel or USB) to the computer. Then, make sure the printer is powered on and follow the installation prompts to complete the setup.

What is the function of a scanner in the context of the lesson?

A scanner is an output device that captures physical documents or images and converts them into digital formats, such as text, documents, or images, which can be edited and stored on a computer.

How has the use of scanners changed with modern technology?

Scanners have become more integrated into other devices like printers, and many smartphones now have apps that can scan documents, making the need for standalone scanners less common.

What was the main advantage of older scanners compared to modern alternatives?

Older scanners were standalone devices that required physical connections to a computer, often via parallel or USB ports. However, modern smartphones and all-in-one printer devices now offer similar functionality with greater convenience and portability.
