Answer: (C) CRT monitor
Answer: (C) CRT monitor
A CRT (Cathode Ray Tube) monitor is a type of display technology that was widely used in older computer systems and televisions. They are characterized by their bulky, heavy design, which resembles traditional TV sets. These monitors use an electron gun to project a beam onto a phosphorescent screen, creating images. Due to their size and weight, CRT monitors are typically used with non-portable computer systems (desktops) and are not suitable for laptops or other mobile devices. Modern display technologies like LCD, LED, and OLED monitors are much thinner, lighter, and more energy-efficient.

The options listed are related to character encoding schemes, which are methods of representing text characters in computers. ASCII (American Standard Code for Information Interchange) is a widely used character encoding standard that represents text in computers, telecommunications equipment, and other devices. BCD (Binary-Coded Decimal) is a method of encoding decimal numbers where each decimal digit is represented by its own binary sequence. While primarily for numbers, it's a form of data representation or "code." EBCDIC (Extended Binary Coded Decimal Interchange Code) is another character encoding standard, primarily used on IBM mainframe operating systems.

Answer: (C) HTML
HTML (HyperText Markup Language) is the fundamental language used to create the structure and content of a web page. While CSS is essential for styling and JavaScript adds interactivity, HTML is the core language that defines the basic building blocks of a website, such as headings, paragraphs, images, and links. Without HTML, you wouldn't have a web page to style or add interactivity to.
