OOPs stands for Object-Oriented Programming, a programming paradigm based on the concept of objects.
OOPs focuses on creating objects that contain data and methods to manipulate that data.
Encapsulation, inheritance, and polymorphism are key principles of OOPs.
Examples of OOP languages include Java, C++, and Python.
Attributes of a fan include size, speed, power source, noise level, and direction of rotation.
Size (e.g. diameter of blades)
Speed (e.g. rotations per minute)
Power source (e.g. electric, battery)
Noise level (e.g. decibels)
Direction of rotation (e.g. clockwise, counterclockwise)
Pipeline in ARM is a technique used to increase the performance of the processor by overlapping the execution of multiple instructions.
Pipeline allows multiple instructions to be processed simultaneously in different stages of execution.
It helps in reducing the overall execution time of a program.
ARM processors typically have a 3-stage pipeline, but some newer designs have more stages for better performance.

There are several algorithms used for classification, including decision trees, logistic regression, k-nearest neighbors, and support vector machines.
Decision trees: a tree-like model where each internal node represents a test on an attribute, each branch represents the outcome of the test, and each leaf node represents a class label
Logistic regression: a statistical method that uses a logistic function to model a...
Check if a tree is balanced by comparing the heights of its left and right subtrees.
Calculate the height of the left subtree and the height of the right subtree.
If the difference between the heights is greater than 1, the tree is not balanced.
Recursively check if both the left and right subtrees are balanced.
If both subtrees are balanced and the height difference is less than or equal to 1, the tree is balanced.
I am interested in various fields of computer science.

DMA stands for Direct Memory Access, a feature that allows hardware devices to transfer data to/from memory without involving the CPU.
DMA is used to offload data transfer tasks from the CPU, improving overall system performance.
Context switching is the process of saving and restoring the state of a CPU so that multiple processes can share the same CPU.
DMA and context switching are both important concepts in embedd...
