I'm guessing the answer is an intranet, based on the description.
However I don't feel qualified to go any deeper than that.
internal Network
If you have gigabit network cards in your PC the internal network will be faster.
Data storage outside (external) or inside (internal) the computer. The location of where the information (files, etc) on your computer system/network.
Internal network structure refers to the arrangement and organization of components within a network that facilitate communication and data exchange. This includes the layout of devices such as routers, switches, and servers, as well as the protocols and technologies used to connect them. A well-designed internal network structure enhances performance, improves security, and allows for efficient management and scalability. It can vary significantly based on the specific needs and size of an organization.
A private or subscription-based in-house network is often referred to as an "intranet." This type of network is designed for internal use within an organization, providing secure access to information, resources, and communication tools for employees. Intranets can facilitate collaboration and streamline workflows while ensuring data privacy and security.
The server you are referring to is known as a "DMZ" (Demilitarized Zone) server. It acts as a buffer zone between a company's internal secure network and the external internet, allowing for controlled access to services like web servers and email while protecting the internal network from potential threats. The DMZ is designed to limit exposure to vulnerabilities, ensuring that even if the DMZ is compromised, the internal network remains secure.
is an internal network that uses Internet technologies
A complex network of nerves is called a neural network or nervous system. This network is responsible for transmitting information throughout the body, coordinating various functions, and responding to internal and external stimuli.
An address that can only be used on the internal network
Direct access is designed to give the user of a computer direct access to their internal network over the internet, and is in many ways similar to VPN's.
First step to design a network is to prepare a layout . Then Protocols which are to be applied are decided. A network can be designed on Packet tracer (software) .
