A) First
B) Second
C) Third

2. Which of the following is a type of computer language?
A) High level
B) Low level
C) Both a and b
D) None of these

3. How much types of computers are?
A) 4
B) 3
C) 5
D) 6
Explanation: Computers are typically classified into three main types based on size and processing power: Supercomputers, Mainframes, and Microcomputers (PCs). Note: Some classification models use four types (adding Minicomputers), but three is a common, simplified modern classification.
4. C is which of the following language?
A) High level language
B) Assembly language

9. Which of the following is impact printer?
A) Line printer
B) Plotter
C) Laser printer
D) Ink jet printer

10. Which of the following is a volatile memory?
A) RAM
B) ROM
C) Both a and b
D) None of these
Explanation: RAM (Random Access Memory) is volatile, meaning it loses its stored data when the power is turned off. ROM (Read-Only Memory) is non-volatile.
