The CPU (Central Processing Unit) is the "brain" of the computer, responsible for executing instructions. It performs this task through a repetitive cycle: Fetch, Decode, Execute. This cycle repeats continuously, allowing the CPU to process a large number of instructions in a short period, enabling the computer to perform tasks and run programs.

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: (B) Samuel Morse
Samuel Morse, an American painter, philanthropist, and inventor, developed Morse Code in 1835. Morse Code is a set of sounds that correspond to letters of the alphabet. In 1838, Morse and his friend Alfred Vail developed the system of dots and dashes that became known as Morse Code.
Morse Code assigns letters and numbers a set of dots and dashes based on their frequency of use. The first telegraph message was sent on May 24, 1844 from Washington, DC to Baltimore. The message was "What hath God wrought!".
