Performance of a reliable storage subsystem for a centralized database system was studied by simulation. The reliable storage subsystem studied consists of three redundant disk units that are updated one at a time from a consistent database state to another consistent database state, Thus, even if a central processor and/or...
A digital computer is characterized by the instruction set it executes. Each machine instruction is a bit pattern which is to be interpreted by the central processing unit CPU. The traditional way to interpret a machine instruction is to use random hardware. A contemporary approach is to install a program...
