Is a set of equipment and software connected to each other by means of physical devices that send and recieve data. It has the purpose of sharing information, resources, offering services and ensuring reliability.

A client is a device with access to resources in another computer known as server usually through a computer network

What is a server

rcesarabc — 2025-09-16 14:25:36 UTC

A server is a hardware device or software program that processes requests from clients over a network and provides responses. It operates within the client-server model, where the server offers services, and the client consumes them. Servers are essential for hosting websites, managing emails, storing files, and running applications.

Servers can be hardware-based, such as powerful physical machines designed to handle multiple requests, or software-based, like programs (e.g., Apache or Nginx) that perform server functions.

ARPANET stands for Advanced Research Projects Agency Network. It was the first wide-area packet-switched network with distributed control and one of the first computer networks to implement the TCP/IP protocol suite. Both technologies became the technical foundation of the Internet.

What is an DNS

A Domain Name Server (DNS) is a fundamental component of the internet infrastructure that translates human-readable domain names (like www.example.com) into numerical IP addresses (such as 192.0.2.1) that computers use to locate each other on the internet. This process is akin to a phonebook for the internet, allowing users to access websites using easy-to-remember names instead of complex numerical addresses.

What is an IP address

An Internet Protocol (IP) address is a unique numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. It serves two main functions: identifying the host or network interface and providing the location of the host in the network, thus enabling the establishment of a path to that host.
