A guest may refer to any of the following:
1. An account that enables a user to gain very limited access to a computer. Although some computer operating systems have default guest accounts, many times this account has to be set up manually by the administrator before it can be accessed.
Unless you plan on having unauthorized users on your computer or network, it is recommended that the guest accounts be disabled to prevent any potential security risks. This account or username is commonly one of the first accounts a potential hacker may try if he or she is unable to gain access to a higher account.
2. Users visiting Computer Hope who are not registered on the Computer Hope forum are considered guests. If you do not want to be identified as a Guest in the Computer Hope chat, either create a free account on the forum or register with the IRC nickserv and identify when logging into the chat.
