- Q2. Binary search tree algorithm
- Ans.
Binary search tree is a data structure where each node has at most two children, with left child smaller and right child larger.
Nodes are arranged in a hierarchical order based on their values.
Searching, insertion, and deletion operations are efficient due to the binary search property.
Example: In a binary search tree, left child of a node has a value less than the node and right child has a value greater than the node

Basic questions based on aptitude, English and reasoning
(5 Questions)
- Q1. What is frequencyand explain it ?
- Ans.
Frequency is the number of cycles per second in a periodic waveform.
Frequency is measured in Hertz (Hz).
It determines the pitch of a sound wave.
Higher frequency means higher pitch and vice versa.
Frequency is used in various fields like electronics, physics, and communication.
Example: The frequency of a radio station is 98.5 MHz.
- Q2. What is wavelength and explain it?
- Ans.
Wavelength is the distance between two consecutive peaks or troughs of a wave.
Wavelength is measured in meters or nanometers.
It determines the color of light and sound frequency.
Shorter wavelengths have higher energy than longer wavelengths.
Examples include the wavelength of visible light, radio waves, and X-rays.
- Q3. Relationship between wavelength and frequency
- Ans.
Wavelength and frequency are inversely proportional to each other.
Wavelength is the distance between two consecutive peaks or troughs of a wave.
Frequency is the number of waves passing through a point in one second.
The higher the frequency, the shorter the wavelength.
The lower the frequency, the longer the wavelength.
The relationship between wavelength and frequency is described by the equation: wavelength = speed of l...
- Q4. What is pulse code modulation
- Ans.
Pulse code modulation is a digital representation of analog signals.
PCM is used to convert analog signals into digital signals.
It involves sampling the analog signal at regular intervals and quantizing the amplitude of each sample.
The resulting digital signal can be transmitted or stored more efficiently than the original analog signal.
PCM is commonly used in audio and video recording and transmission.
It is also used i

- Q1. Questions based on resume
- Q2. Digital Circuits , how do they work ?
- Ans.
Digital circuits are electronic circuits that operate using digital signals (0s and 1s) to perform logical operations.
Digital circuits use logic gates to process binary information.
They can perform operations such as AND, OR, NOT, and XOR.
These circuits are the building blocks of computers and other digital devices.
Examples of digital circuits include flip-flops, registers, and arithmetic logic units.
- Q3. How do Logic gates work ?
- Ans.
Logic gates are electronic devices that perform logical operations based on input signals.
Logic gates take input signals and produce an output signal based on a specific logic function.
They can perform operations such as AND, OR, NOT, NAND, NOR, XOR, and XNOR.
For example, an AND gate outputs a high signal only when both input signals are high.
A NOT gate inverts the input signal, producing a high output when the input i...
