Question:
Which one of the following is not I/O device ?
Which one of the following is not I/O device ?
Show Hint
Think of I/O devices as the "senses" of the computer (seeing, hearing, speaking), while Memory and the CPU are the "brain" itself.

The Correct Option is D
Solution and Explanation
Concept:
I/O (Input/Output) devices are hardware components used to communicate between a user and a computer. Input devices send data to the system, while output devices represent the results of processed data.
Step 1: Evaluate Input and Output options.
- Terminal: A terminal consists of a keyboard (input) and a monitor (output), making it a classic I/O device. - Printer: A printer is a primary output device that produces a hard copy of electronic data. - Disk: Hard disks or floppy disks are considered secondary storage/IO devices because data can be read from them (input) and written to them (output).
Step 2: Identify the non-I/O component.
Memory (specifically Primary Memory or RAM) is an internal component of the computer's central architecture. Its primary role is to hold data and instructions that the CPU is currently processing.
Step 3: Conclusion.
While data moves in and out of memory, it is classified as a storage/processing component rather than a peripheral I/O device used for external communication.

- Which of the following statements are correct?
A. In a skew-symmetric matrix, all diagonal elements are zero.
B. A square matrix is called a diagonal matrix if all its non-diagonal elements are one.
C. If the determinant of the matrix is zero, then the matrix is known as non-singular matrix.
D. The product of a matrix A and its adjoint is equal to unit matrix multiplied by the determinant A. Match LIST-I with LIST-II
LIST-I (Differential Equation)
(A) \(\frac{dy}{dx} = 2x(y-x^2+1)\)
(B) \(x\frac{dy}{dx} + 2(x^2+1)y=6\)
(C) \((x^2+1)\frac{dy}{dx} + 2xy = x \sin x\)
(D) \(x^3\frac{dy}{dx} + 2xy = 2x^2e^{x^2}\)
