The Correct Answer is : IP address Explanation & Key Takeaways: • An Internet Protocol address (IP address) is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. e.g - The format of the IP address is 168.212.226.204 represents the 32- bit binary number. Important Notes: • Every web-capable device needs an IP (Internet Protocol) address to enable it to access the Internet. Without an IP address, computers wouldn't be able to communicate with each other. Every internet-capable device, from your computer to your smartphone, has its own unique identifying IP address. Some Important Notes: to remember about IP address are: • IP address stands for Internet Protocol address. • An IP address is a 32-bit number that is sub-divided into four bytes. • It is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. • There are two versions of IP address: IPv4 (32 bits) and IPv6 (128 bits). Related Concepts: e-mail address: • An email address identifies an email box to which messages are delivered. • An email address, such as john.smith@example.com, is made up of a local-part, the symbol @, and a domain, which may be a domain name or an IP address enclosed in brackets. MAC address: • A media access control address (MAC address) is a unique identifier assigned to a network interface controller (NIC) for use as a network address in communications within a network segment. • This use is common in most IEEE 802 networking technologies, including Ethernet, Wi-Fi, and Bluetooth. Memory address: • In computing, a memory address is a reference to a specific memory location used at various levels by software and hardware. • Memory addresses are fixed-length sequences of digits conventionally displayed and manipulated as unsigned integers.
