The correct answer is: B. Bit map terminal
A bit map terminal is a type of computer terminal that displays text and graphics as a series of dots, or pixels. Each pixel can be either on or off, which allows for a wide range of possible images to be displayed.
A character map terminal, on the other hand, displays text as a series of characters, each of which is represented by a unique code. This type of terminal is less versatile than a bit map terminal, as it cannot display graphics.
An RS-232 C terminal is a type of serial communication device that uses the RS-232 C protocol to communicate with a computer. This protocol is used to transmit data between two devices, such as a computer and a modem.
Therefore, the only type of terminal that displays the screen as an array of pixels is a bit map terminal.
