1. A computer or microchip, comprising: a master controlling microprocessor and firmware of the computer or microchip, an internal hardware firewall located between a protected portion of the computer or microchip that is protected by the internal hardware firewall and a network portion of the computer or microchip, the network portion having a connection for a network of computers including the World Wide Web and/or the Internet; the internal hardware firewall denies access to at least the protected portion of the computer or microchip from the network; and network communications devices located in the network portion of the computer or microchip; and one or more or at least two or four or eight or 16 or 32 or 64 or 128 or 256 or 512 or 1024 microprocessors or processing units, each with associated random access memory (RAM), that are not network communications devices, wherein the one or more microprocessors or processing units and random access memory (RAM) are located in the network portion of the computer or microchip and are separate from the internal hardware firewall; and wherein a location of the internal hardware firewall permits unrestricted access by the network of computers to the network portion of the computer or microchip so that processing operations other than network communications and firewall operations conducted by the computer or microchip with the network of computers are executed by one or more of the microprocessors or processing units and random access memory (RAM) in the network portion of the computer or microchip: and wherein the master controlling microprocessor and at least a part of the firmware are located in the protected portion of the computer or microchip and the master controlling microprocessor has preemptive control of the one or more microprocessors or processing units and associated random access memory (RAM) in the network portion of the computer or microchip, and the preemptive control including erasure of at least a part of the random access memory (RAM) associated with at least one of the one or more microprocessors or processing units in the network portion of the computer or microchip prior to use of the network portion of the computer or microchip by a user or operating system of the computer or microchip.
