## How does the binary search algorithm work?

Binary search is an efficient algorithm for finding an item from a sorted list of items. It works by **repeatedly dividing in half the portion of the list that could contain the item, until you’ve narrowed down the possible locations to just one**.

## What is CPU scheduling in operating system?

CPU Scheduling is **a process that allows one process to use the CPU while another process is delayed (in standby) due to unavailability of any resources such as I / O etc, thus making full use of the CPU**. The purpose of CPU Scheduling is to make the system more efficient, faster, and fairer.

## What is deterministic modeling in operating system?

Deterministic modeling is **one type of analytic evaluation**. This method evaluates a specific algorithm by comparing the efficiencies of different algorithms on a specific, predetermined workload.

## How do you debug a machine learning model?

Debugging steps in the software world

**Inspect the system thoroughly to find it**. Analyze the Error: Analyze the code to identify more issues and estimate the risk that the error creates. Prove the Analysis: Work with automated tests, after analyzing the bug you might find a few more errors in the application.

## What is the difference between artificial intelligence and machine learning?

An “intelligent” computer uses AI to think like a human and perform tasks on its own. **Machine learning is how a computer system develops its intelligence**. One way to train a computer to mimic human reasoning is to use a neural network, which is a series of algorithms that are modeled after the human brain.

## What does an algorithm need?

In the most general sense, an algorithm is **a series of instructions telling a computer how to transform a set of facts about the world into useful information**. The facts are data, and the useful information is knowledge for people, instructions for machines or input for yet another algorithm.

## How many types of algorithm are there?

There are **seven** different types of programming algorithms: Sort algorithms. Search algorithms. Hashing.

## What is pseudo code in Python?

Pseudocode is **a way of expressing an algorithm without conforming to specific syntax rules**. By learning to read and write pseudocode, you can easily communicate ideas and concepts to other programmers, even though they may be using completely different languages.
