What is the full form of RAM?
- A.
  
  Read only memory
- B.
  
  Right only memory
- C.
  
  Random access memory
Correct Answer
C. Random access memory

Explanation
RAM stands for Random Access Memory. It is a type of computer memory that allows data to be accessed randomly, meaning any byte of memory can be accessed without touching the preceding bytes. This makes it faster and more efficient compared to other types of memory like read-only memory (ROM) or write-only memory (WOM). RAM is used by the computer's operating system, software applications, and data that is currently being processed or used by the computer.

The "COMPOSE" button is used to start writing a new email, and the "ATTACHMENT" button is used to add attachments to the email.

A.L.U. PERFORMS ONLY FUNCTIONS.
- A.
  
  LOGICAL
- B.
  
  ARITHMATIC
- C.
  
  ARITHMATIC AND LOGICAL FUNCTIONS
Correct Answer
C. ARITHMATIC AND LOGICAL FUNCTIONS

Explanation
The correct answer is "ARITHMATIC AND LOGICAL FUNCTIONS". An Arithmetic Logic Unit (ALU) is a digital circuit that performs arithmetic and logical operations on input data. It is a fundamental component of the central processing unit (CPU) in a computer. The ALU can perform arithmetic operations such as addition, subtraction, multiplication, and division, as well as logical operations such as AND, OR, NOT, and XOR. Therefore, the statement "ALU performs only functions" is incorrect, as the ALU performs both arithmetic and logical functions.

Explanation
Mozilla Firefox is not a search engine. It is a web browser that allows users to access the internet and search for information using various search engines like Google or Yahoo. While Google and Yahoo are search engines that provide users with search results based on their queries, Mozilla Firefox is simply a tool that allows users to navigate the internet and access different websites.
