Networking Concepts Quiz

A security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules.

A network where all devices are connected to a central hub or switch.

The protocol used for transmitting web pages. Its secure version, HTTPS, encrypts data for secure communication.

A network device that amplifies and retransmits signals to extend the range of a network.

A device that converts digital data into analog signals for transmission over telephone lines and vice versa, providing internet access.

A network where devices are connected in a ring. Data flows in one direction, and while it ensures efficient data transmission, a failure in the ring can disrupt the entire network.

A protocol used to send and receive emails over the internet.

An organized collection of data, typically stored and accessed electronically from a computer system.

A type of database structure that stores data in tables, allowing relationships between different data items using keys.

A standardized language used to manage and manipulate relational databases, including operations like querying, updating, and deleting data.

A structured approach to software development, involving planning, analysis, design, implementation, testing, and maintenance.

The stage in SDLC where system requirements are gathered and analyzed to ensure the software meets user needs.

The tendency of a project's scope to expand beyond its original objectives, often due to adding new features or requirements.

A development approach that follows a well-defined and linear sequence, like the Waterfall model.

An iterative and collaborative approach to software development where requirements and solutions evolve through cross-functional teamwork.

A combination of development and operations practices to automate software development, testing, and deployment.

A device used to filter and forward traffic between two network segments, improving performance and dividing traffic.

A system for managing relational databases, where data is stored in tables that are related to each other using keys.

A method of transitioning from an old system to a new one, where both systems operate simultaneously for a period of time.

A basic visual representation of a website's layout, showing the structure and navigation without detailed design.

A unique string of numbers assigned to devices connected to the internet, used to identify and locate them.

A type of bar chart used in project management to visually represent the timeline of tasks and activities in a project.

A service that allows individuals or organizations to publish their website on the internet.

A programming language used to create dynamic and interactive effects within web browsers.

A base-2 numeral system that represents values using only two symbols: 0 and 1. These two symbols correspond to the two possible states of an electronic circuit (off and on), making binary the language of computers.

Development and operations practices aimed at shortening the systems development life cycle and providing continuous delivery of high-quality software.

A security testing method used to identify vulnerabilities in a system by simulating attacks.

In computers, data is stored, processed, and transmitted in binary form. Each binary digit (bit) can represent two possible states: 0: Off, false, or no current. 1: On, true, or current.

To convert from binary to decimal, take each bit (starting from the right), multiply it by its corresponding power of 2, and then sum the results.

Unlike the decimal system (base-10), which uses 10 digits (0-9), binary relies on just two symbols to represent all numeric values.

A binary digit, represented as 0 or 1. In electrical terms, 1 is 'high voltage' (on) and 0 is 'low voltage' (off).

In the binary system, each position in a number represents a power of 2. This is similar to how in the decimal system, each position represents a power of 10.

To convert a binary number to decimal, multiply each bit by its corresponding power of 2 and then sum the results.

To convert a decimal number to binary, repeatedly divide the decimal number by 2, recording the quotient and remainder at each step. The binary number is formed by reading the remainders from bottom to top.

Adding binary numbers is similar to decimal addition, but the carry-over happens when the sum reaches 2 (10_2).

Subtracting in binary is similar to decimal subtraction, involving borrowing from higher place values when the subtracted bit is larger. This is achieved by 'borrowing' a 1 from the next higher place value.

Multiplying and dividing binary numbers are similar to decimal operations, but simpler due to the limited digits 0 and 1.

A group of 8 bits. A byte represents a single character, like a letter or number.

Larger units of data storage, such as kilobytes (kB), megabytes (MB), gigabytes (GB), terabytes (TB), petabytes (PB).
