A camera sensor is a device that converts light into electrical signals to capture images. Sensors vary in size and are used in digital cameras, smartphones, and other imaging devices.

• Camera sensor converts light into electrical signals to capture images

• Common sensor sizes include full-frame, APS-C, Micro Four Thirds, and 1-inch sensors

• Used in digital cameras, smartphones, security cameras, and other imaging devices

A server is a computer or software that provides functionality or resources to other devices on a network. It differs from a PC in terms of its purpose and capabilities.

• A server is designed to provide services or resources to other devices on a network, such as hosting websites, storing files, or managing network traffic.

• Servers typically have more powerful hardware components, such as faster processors, more memory, and larger storage capacity, compared to a typical PC.

• Serve...read more

A mobile device connects to a network through wireless communication protocols like Wi-Fi, Bluetooth, or cellular data.

• Mobile device scans for available networks

• User selects a network and enters password if required

• Device sends a connection request to the network

• Network authenticates the device and assigns an IP address

• Device is now connected to the network and can access the internet

OSI layer is a networking model with 7 layers. Bandwidth refers to the maximum data transfer rate of a network or internet connection.

• OSI layer is a networking model that divides network communication into 7 layers.

• Each layer has specific functions and protocols to facilitate communication between devices.

• Bandwidth refers to the maximum rate at which data can be transferred over a network or internet connection.

• It is typically measured in bits per second (bps) or bytes per se...read more

Polymorphism is the ability of an object to take on many forms. It allows objects of different classes to be treated as the same type.

• Polymorphism is a fundamental concept in object-oriented programming.

• It allows a single interface to be used for different types of objects.

• Polymorphism can be achieved through method overriding and method overloading.

• Example: A shape class with different subclasses like circle, square, and triangle.

• Example: A print method that can accept diffe...read more

Optimizing website performance involves various techniques such as minimizing HTTP requests, optimizing images, using caching, and reducing server response time.

• Minimize HTTP requests by combining CSS and JavaScript files

• Optimize images by using the correct file format and size

• Utilize browser caching to store static resources locally

• Reduce server response time by optimizing code and database queries

Event Loop in Node.js is a mechanism that allows Node.js to perform non-blocking I/O operations.

• Event Loop is responsible for handling asynchronous operations in Node.js.

• It allows Node.js to perform multiple operations simultaneously without blocking the execution.

• Event Loop continuously checks the event queue for any pending tasks and executes them in a loop.

• Example: setTimeout() function in Node.js uses Event Loop to schedule the callback function after a specified delay.

SQL joins are used to combine rows from two or more tables based on a related column between them.

• Types of SQL joins include INNER JOIN, LEFT JOIN, RIGHT JOIN, and FULL JOIN.

• INNER JOIN returns rows when there is at least one match in both tables.

• LEFT JOIN returns all rows from the left table and the matched rows from the right table.

• RIGHT JOIN returns all rows from the right table and the matched rows from the left table.

• FULL JOIN returns rows when there is a match in one of ...read more

Common types of network topologies include bus, star, ring, mesh, and hybrid.

• Bus: all devices are connected to a central cable

• Star: all devices are connected to a central hub

• Ring: each device is connected to two other devices, forming a ring

• Mesh: each device is connected to every other device

• Hybrid: combination of two or more different topologies

Functional programming is a programming paradigm that treats computation as the evaluation of mathematical functions and avoids changing state and mutable data.

• Focuses on pure functions that do not have side effects

• Avoids mutable data and state changes

• Uses higher-order functions and function composition

• Supports recursion and immutability

• Examples include languages like Haskell, Scala, and Clojure

Intersection of linked list is finding the common node where two linked lists meet.

• Traverse both linked lists and find the lengths

• Align the longer list's head to match the length of the shorter list

• Iterate through both lists and compare nodes to find intersection

In my previous company, I focused on delivering tailored solutions to enhance client satisfaction and operational efficiency.

• Collaborated with cross-functional teams to identify client needs and develop customized solutions.

• Implemented a new CRM system that improved client tracking and communication, resulting in a 20% increase in client retention.

• Conducted regular training sessions for staff on new technologies and processes to ensure smooth adoption.
