Computer Science Quiz

A router is a hardware device used in networking, not software. Operating systems, compilers, and spreadsheets are all software applications.

HTTP is the protocol used for transferring hypertext requests and information on the World Wide Web.

JavaScript is a widely-used language in web development, particularly for client-side scripting to create dynamic, interactive web pages.

Open-source software allows anyone to inspect, modify, and distribute the source code, typically under a license that promotes collaboration.

A stack follows the LIFO principle, where the last element added is the first one to be removed.

MySQL is an example of an RDBMS, which organizes data into tables that can be related to one another

An operating system acts as an intermediary between the computer hardware and application software, managing resources such as memory, processing power, and storage.

Merge Sort has a time complexity of O(n log n), making it more efficient for large datasets compared to bubble sort, insertion sort, and selection sort, which have O(n^2) time complexities.

MongoDB is a NoSQL database, which stores data in a non-relational format, often as key-value pairs, documents, or graphs, making it suitable for unstructured data.

Git is a version control system that tracks changes in source code, allowing multiple developers to collaborate and manage different versions of the codebase.

A compiler translates code written in high-level programming languages into machine code or intermediate code, which can be executed by a computer.

A linked list allows for dynamic memory allocation and doesn't require a fixed size, whereas an array has a predefined size that must be known in advance.

O(n^2) is considered quadratic time complexity, indicating that the time required grows proportionally to the square of the size of the input.

HTTPS (HyperText Transfer Protocol Secure) is an extension of HTTP that uses encryption protocols like SSL/TLS to ensure secure communication over the internet.

A deadlock occurs when two or more processes are waiting for each other to release resources, causing all of them to remain stuck indefinitely.

A primary key is used to uniquely identify each record in a table, ensuring that no two records have the same primary key value.
