What process occurs in the CPU when pressing the key for letter A?

When you press the key for the letter A, the CPU processes that input by converting the character into a format that can be understood and manipulated by the computer. This conversion involves transforming the letter A into its corresponding ASCII binary code. ASCII, which stands for American Standard Code for Information Interchange, assigns a unique binary number to each character. In the case of A, the ASCII code is 65, which is represented in binary form as 01000001.

This process is crucial for the computer to handle and display the letter A accurately, allowing it to be stored in memory, sent to output devices, or processed further in applications. The other choices do not correctly describe what occurs during the keypress: for instance, option about sending directly to the printer would not occur until after additional processing, and ignoring the letter is simply not a viable action when a key is pressed. The option about sending a signal to the GPU is unrelated to the immediate handling of keyboard input in this context.
