How many fields does a database have?
Modern databases do not have a preset number of fields. Rather, the data architect determines the needed tables and number of fields per table and declares that to the database software. Fields can--with some restrictions--also be added and removed later as needed. That said, each database application does have a maximum limit on the number of fields per table and the number of tables per database, which information has to come from the database manufacturer. But those limits are usually vastly greater than anyone might want. It is part of a computer and it has many fields.

In a peer to peer network only the central host computer supplies the resources the other computers request resources from this host?
No - a peer to peer network means that every device (even a standalone server) has the same authority in the network. Each device can choose to share resources with other devices in the network. In such a network there really isn't a 'central host' computer, unless you put a file or print or database service on a server that the other devices might want access to.

What is the main computer that connects the other computers?
Strictly speaking, no computer 'controls' a network. You will have different devices that do different jobs on a network. Some examples : You might have a DOMAIN CONTROLLER on a Microsoft network that authenticates users of the network (allows users to login and use the network resources). You might have ROUTERS that 'control' what data gets in and out of a network based upon its configuration and which network data might get forwarded to as necessary. You might have SWITCHES that 'control' what data gets sent to which computer based upon an IP address' host bits. You might have a GATEWAY that 'controls' what data passes in and out of a company's internal network onto an external network (such as the Internet) If you want a simple answer then it's probably that a SERVER 'controls' a client-server network.
