In this game, a server refers to a computer that can be connected to, accessed, and manipulated through the Terminal. All servers in the game are connected to each other to form a large, global network. To learn about how to navigate this network and connect to other servers, see the Terminal page.
Perhaps the most important property of a server to make note of is its RAM, which refers to how much memory is available on that machine. RAM is important because it is required to run Scripts. More RAM allows the user to run more powerful and complicated scripts as well as executing a script with more threads.
The free, scan-analyze, and analyze Terminal commands can be used to check how much RAM a server has.
A server is identified by its hostname. A hostname is a label assigned to a server. A hostname will usually give you a general idea of what the server is. For example, the company Nova Medical might have a server with the hostname “nova-med”.
Hostnames are unique. This means that if one server has the the hostname “some-server”, then no other server in the game can have that that hostname.
The player starts with a single server: his/her home computer. This server will have the hostname “home.” The player’s home computer is special for a variety of reasons:
1. The home computer’s RAM can be upgraded. This can be done by visiting certain locations in the World.
2. The home computer persists through Augmentation Installations. This means that you will not lose any RAM upgrades or Scripts on your home computer when you install Augmentations (you will however, lose programs and messages on your home computer).
The player can also purchase additional servers. This can be
done by visiting certain locations in the World, or it can be
done automatically through a script using the
Netscript Function. The advantage of purchased servers is that,
in terms of RAM, they are cheaper than upgrading your home
computer. The disadvantage is that your purchased servers
are lost when you install Augmentations.
