Question 1

TCP

Answer 1

Transmisson Control Protocol is a core protocol of the Internet Protocol Suites which provides a reliable, ordered, error-checked delivery pf data between applications running on hosts communicating via an IP network.

Question 2

UDP

Answer 2

User Datagram Protocol is a simpler and faster protocol than TCP, it’s used to send data without guaranteeing delivery or order, making it ideal for applications like video-streaming or online gaming where speed is more important than reliability.

Question 3

Machine Learning

Answer 3

Machine Learning is an area of artificial intelligence which allows the computer to learn and make predictions based on data, improving as it is exposed to more information.

Question 4

Virtual Machine

Answer 4

Virtual Machine is a software which allows an operating system to run inside another operating system. The Virtual Machine is separated from the host operating system, both of them having they’re own virtual hardware and resources.

Question 16

Interpreted Language

Answer 16

Interpreted language executes the source code line-by-line by using an interpreter

Question 17

Compiled Language

Answer 17

Compiled Language converts the source code into machine code to run or intermediates code before executing using a compiler.

Question 18

Difference between Interpreted Language and Compiled Language

Answer 18

The difference between Interpreted Language and Compiled Language is the way they execute code; one by using an interpreter the other by converting source code into machine code or by utilizing a converter.
