Answer: Central Processing Unit (CPU)

Step by step solution

Understanding the CPU function

The missing term we are looking for is the Central Processing Unit (CPU). The CPU is the primary component of a computer system that is responsible for carrying out instructions and performing operations. It's often referred to as the "brain" of the computer.

Fetching Instructions

The first function of the CPU is to fetch instructions. The CPU fetches instructions from the memory, which contains programs and data that the CPU will process. The instructions are fetched one at a time and brought to the CPU for processing.

Carrying out Operations

The second function of the CPU is to carry out the operations commanded by the instructions. Once an instruction is fetched, the CPU decodes it and determines which operation to perform. The CPU then performs the required operation on the given data, following the instruction's command.

Producing Outcomes or Resultant Information

The final function of the CPU is to produce an outcome or resultant information. After carrying out the operation, the CPU produces a result, which it either stores back in the memory or uses as input for the next instruction. So, the complete sentence would be: "The job of the Central Processing Unit (CPU) is to fetch instructions, carry out the operations commanded by the instructions, and produce some outcome or resultant information."
