What does Bubble Sort do in an unsorted list?

Bubble Sort compares adjacent items and switches their places until the list is sorted.

How does Merge Sort function?

Merge Sort divides the list in half until the size is 1, then compares and sorts the list.

What is Binary Search used for?

Binary Search finds the position of a target value within a sorted array by halving the search interval.

What is the difference between Linear Search and Binary Search?

Linear Search checks each item one by one, while Binary Search is more efficient but requires a sorted list.

What does it mean to traverse a string?

String traversal means to loop through each character in a string.

What is an Array in data structures?

An Array is a collection of elements of the same data type.

What is a Record in data structures?

A Record contains fields of different data types that are related, such as name, age, and gender.

What characterizes a Function in programming?

A Function always returns a value to the main program.

What is a Run-time error?

A run-time error occurs during program execution and is the hardest to spot.

How does an Arithmetic Shift differ from a Logic Shift?

An Arithmetic Shift is used with signed numbers and keeps the leftmost bit unchanged, while a Logic Shift replaces blank spaces with zeros.

What does ASCII stand for?

ASCII stands for American Standard Code for Information Interchange.

What is Virtual Memory?

Virtual Memory is used when RAM is full, allowing the operating system to swap unused programs to the hard disk.

What is the clock speed in relation to processor performance?

Clock speed refers to the number of cycles per second that a processor can execute.

What is the difference between RAM and ROM?

RAM is volatile and loses data when powered off, while ROM is non-volatile and stores permanent data.

What is a Client-server network?

A Client-server network has at least one server that provides services to client computers.

What is the function of the Internet Protocol (IP)?

The Internet Protocol (IP) governs how data is transmitted over a network.

What is File Transfer Protocol (FTP)?

FTP is a protocol that defines how files are transmitted between computers.

How do Mobile Networks 4G and 5G differ?

4G offers increased data transmission speed, while 5G provides smarter, faster connectivity with lower latency.

What is the function of DNS in the internet?

DNS translates domain names to IP addresses so that computers can locate each other on the Internet.

What is DNA computing?

DNA computing uses molecules of DNA to process information, enabling parallel processing for complex problem-solving.

How does Quantum computing differ from traditional computing?

Quantum computing uses qubits that can exist in multiple states simultaneously, allowing faster processing.

What is Nanotechnology?

Nanotechnology involves building machines and circuits at the atomic and molecular level, leading to highly efficient processing.
