• Identify the node to be deleted

• Update the previous node's next pointer to point to the next node

• Update the next node's previous pointer to point to the previous node

• Free the memory occupied by the node

Fourier transform is a mathematical technique that transforms a signal from time domain to frequency domain.

• It is used in signal processing to analyze and filter signals

• It is used in image processing to extract features and compress images

• It is used in audio processing to remove noise and enhance sound quality

• It is used in cryptography to encrypt and decrypt data

• It is used in quantum mechanics to describe the behavior of particles

• It is used in many other fields such as financ...read more

Filters are used to sort, group, or limit data based on specific criteria.

• Filters are used to refine data by selecting specific criteria.

• They can be used to sort data in ascending or descending order.

• Filters can also be used to group data based on specific attributes.

• They can be used to limit the amount of data displayed.

• Examples of filters include date range filters, category filters, and search filters.

Code to print linked list reversely

• Traverse the linked list and push each node into a stack

• Pop each node from the stack and print its value

A microprocessor is a small electronic chip that serves as the central processing unit (CPU) of a computer.

• It is responsible for executing instructions and performing calculations in a computer.

• It is made up of millions of transistors that work together to process data.

• Examples include Intel's Pentium and AMD's Ryzen processors.

• It is the brain of a computer and determines its processing power.

• It is found in a variety of devices, including smartphones, tablets, and cars.

The latest processor is the Intel Core i9-11900K.

• The Intel Core i9-11900K was released in March 2021.

• It has a base clock speed of 3.5 GHz and a boost clock speed of 5.3 GHz.

• It has 8 cores and 16 threads.

• It uses the LGA 1200 socket and is compatible with Intel 500-series motherboards.

Pin diagram of 8086 microprocessor.

• 8086 has a 40-pin dual in-line package (DIP).

• Pins are grouped into power supply, data bus, address bus, control and status signals.

• Pin 1 is at the top left corner and pin 40 is at the bottom right corner.

• Examples of pins: A0-A15 (address bus), D0-D15 (data bus), RD (read), WR (write), CLK (clock).

FSK stands for Frequency Shift Keying, a digital modulation technique used in communication systems.

• FSK is a form of frequency modulation where the frequency of the carrier signal is shifted between two or more frequencies to represent digital data.

• It is commonly used in applications such as radio broadcasting, wireless data transmission, and RFID systems.

• In FSK, the amplitude and phase of the carrier signal remain constant while the frequency changes.

• FSK can be binary or mul...read more
