Which type of computer is a large, powerful and expensive one that can support many users at one time, store vast amounts of data, and perform many tasks at the same time?

Question

Given below are two statements.
Assertion (A):
For a random variable \(X\), if \(x=0,1,2,\ldots\) and \[ P(X=x)=k\frac{\lambda^x}{x!}, \] then for it to be a probability mass function, \(k=e^{-\lambda}\).
Reason (R):
In a probability distribution, the sum of all probabilities must be \(1\).

Answer 1

Step 1: Computer Types
- Personal Computer: Compact, for single users.
- Mini Computer: Medium-sized, supports limited users.
- Micro Computer: Small, microprocessor-based computer.
- Mainframe Computer: Large, powerful; supports many users and massive data storage.

Step 2: Identification
The description corresponds to a Mainframe Computer.
