12.
Which of the following printers consists of a steel band on which characters are embossed?
Correct Answer
C. Chain printer
Explanation
A chain printer consists of a steel band on which characters are embossed. This band, known as the chain, contains the characters that need to be printed. As the chain rotates, the embossed characters strike an inked ribbon, transferring the ink onto the paper, thus creating the printed output. This mechanism allows for fast and reliable printing, making chain printers suitable for high-volume printing tasks. In contrast, line printers use a line of type to print characters, and drum printers use a rotating drum with characters engraved on its surface. None of these printers use a steel band with embossed characters.

The language in which data is represented in terms of dens and zeros and programs can be executed directly by the computer is called __________.
Correct Answer
D. Machine language
Explanation
Machine language is the correct answer because it refers to the language in which data is represented using binary code, consisting of ones and zeros. Programs written in machine language can be executed directly by the computer's hardware. Assembly language is a low-level language that uses mnemonic codes to represent machine language instructions. High-level languages are more user-friendly and require a compiler or interpreter to convert the code into machine language. Binary coded language is not a commonly used term in computer science.

The variables that can have values in the form of a sequence of characters and are represented by an alphabet and a '&' sign at the end is called _________.
Correct Answer
C. String variable
Explanation
A string variable is a type of variable that can hold a sequence of characters. It is represented by an alphabet and an '&' sign at the end. This type of variable is used to store textual data such as names, sentences, or any other combination of characters. It is different from numeric values or characters, as it can store a sequence of characters rather than just a single character or a numerical value. Therefore, the correct answer is string variable.
