Host Description

The term host is used in various contexts and areas with different meanings. In the Internet Protocol (TCP/IP) specification, it refers to any computer with full access to other two-way computers via the Internet.

A host has a unique IP address with its network number. For example, if you use the Point-to-Point Protocol to access your provider, you will have a public IP address during any connection to the Internet, and your computer will act as a Host during that connection.

Between all the computers used in a local network, your computer will be the Host between the computer you use and the workstation on which you communicate data.

Computers that companies host websites or computers used by individual users as Web Server are called a Host.

A hosting company that hosts and serves websites can also be called Host.

You can better understand what the term means with the example of naming the system containing the data as the host, and the computer where the user resides as the remote terminal.

The point to be noted here is that the term is completely different from the Client/Server relationship.

In operating systems, the term traditionally refers to a computer that provides service to computer terminals for multiple users, software, equipment to serve smaller or less capable devices that provide a service for teletypewriter or video terminals.

In addition, this term is used in a series of Request for Comments (RFC) documents that define ARPANET.

While ARPANET was being developed, networked computers were typically main port computer systems, which were accessible from terminals connected through serial ports.

These terminals cannot perform calculations on their own or host the software, so they are not considered to be Hosts.

Users using mainframes can request the same services from other machines connected to the network. In general, the host computer is all computer equipment that has an IP address and is connected with one or more computers.

Hosting is a service that many companies offer to their users or other companies. In short, users’ web pages and data are stored and served on company computers.

For example, it ensures that a web page is always available, even if it is not a PC connected to the creators.

Computers hosting this data can present data faster, best manage traffic, and generally improve the access of these pages/data for potential users.
