Horizontal scaling involves adding more machines to distribute load, while vertical scaling involves increasing the power of existing machines.

• Horizontal scaling adds more machines to handle increased load

• Vertical scaling increases the power of existing machines

• Horizontal scaling is more cost-effective and easier to implement

• Examples of horizontal scaling include adding more servers to a cluster

• Examples of vertical scaling include upgrading a server's CPU or RAM

Various programming languages are used in web development, each with its own strengths and purposes.

• HTML

Caching in web development involves storing copies of files or data in a temporary location to reduce load times and improve performance.

• Caching helps reduce server load by serving cached content instead of generating it from scratch.

• Common types of caching include browser caching, server-side caching, and database caching.

• Examples of caching techniques include using HTTP headers to control browser caching, implementing a content delivery network (CDN) for static assets, and ...read more

Binary search algorithm is a divide and conquer algorithm that searches for a target value within a sorted array.

• Binary search compares the target value to the middle element of the array and eliminates half of the remaining elements based on the comparison.

• Time complexity of binary search is O(log n) where n is the number of elements in the array.

• Example: Searching for the value 7 in the sorted array [1, 3, 5, 7, 9, 11] would take 3 comparisons in binary search.

Testing is the process of evaluating a system or application to find defects or bugs, while debugging is the process of identifying and fixing those defects.

• Testing involves executing the system or application to identify defects or bugs.

• Debugging involves identifying and fixing the defects found during testing.

• Testing is done by testers, while debugging is usually done by developers.

• Examples of testing include unit testing, integration testing, and user acceptance testing.

• Ex...read more

Data structure is a way of organizing and storing data in a computer so that it can be accessed and used efficiently. Algorithms are step-by-step procedures for solving problems.

• Data structure refers to the way data is organized and stored in a computer system.

• Algorithms are step-by-step procedures for solving problems or performing tasks.

• Examples of data structures include arrays, linked lists, trees, and graphs.

Database partitioning is the process of splitting a large database into smaller, more manageable parts.

• Improves performance by distributing data across multiple servers or disks

• Helps with scalability and maintenance

• Types include horizontal partitioning (rows) and vertical partitioning (columns)

• Example: Partitioning a customer database by region to improve query performance
