Bubble sort is a simple sorting algorithm that repeatedly steps through the list, compares adjacent elements and swaps them if they are in the wrong order.

• Bubble sort has a time complexity of O(n^2)

• It is not efficient for large datasets

• It is easy to implement and understand

• Example: [5, 3, 8, 4, 2] -> [2, 3, 4, 5, 8]

JavaScript cannot be embedded directly in CSS, but can be used in conjunction with CSS to manipulate styles dynamically.

• JavaScript can be used to dynamically change CSS properties of elements on a webpage

• This can be achieved by selecting the element using JavaScript and then modifying its style properties

Static keyword is used to preserve the value of a variable between function calls.

• Static variables are initialized only once and retain their value between function calls.

• They are useful in situations where we need to maintain state across function calls.

• Static keyword can also be used to limit the scope of a variable to a single file.

• Memory loss refers to the inability to remember things, it is not related to the stat...read more

A pointer is a variable that stores the memory address of another variable. It is used to manipulate data indirectly.

• Pointers are used to dynamically allocate memory

• Pointers are used to pass arguments by reference

Adhoc network is a decentralized wireless network formed by devices communicating directly with each other.

• No central access point

• Devices communicate directly with each other

• Can be formed temporarily

• Used in emergency situations or in areas with no existing network infrastructure

3G and 4G are mobile network technologies. G stands for generation.

• 3G provides faster data transfer rates than 2G, while 4G provides even faster rates than 3G.

• 4G also supports advanced features like VoLTE and carrier aggregation.

• G stands for generation and refers to the evolution of mobile network technology.

• 5G is the latest generation of mobile network technology, offering even faster speeds and lower latency.
