An internal storage consisting of arrays of small rings of magnetic material called ferrite is Magnetic core.

A magnetic core is a piece of magnetic material with a high magnetic permeability used to confine and guide magnetic fields in electrical, electromechanical and magnetic devices such as electromagnets, transformers, electric motors, generators, inductors, magnetic recording heads, and magnetic assemblies.

To set a register or computer to the all-zero state is Reset

A processor register (CPU register) is one of a small set of data holding places that are part of the computer processor. A register may hold an instruction, a storage address, or any kind of data (such as a bit sequence or individual characters). Some instructions specify registers as part of the instruction.

Many CPUs now have general purpose registers (GPRs), which may contain both data and memory addresses. Registers vary in both number and size, depending on the CPU architecture. Some processors have 8 registers while others have 16, 32, or more. For many years, registers were 32-bit, but now many are 64-bit in size.

Reliability refers to the ability with which the computers remain functional to serve the user. Computer systems are well-adopted to performing repetitive operations. They are immune to tiredness, boredom or fatigue.

An adder in which the bits of the operands are added one after another is Serial adder.

Serial binary adder. The serial binary adder or bit-serial adder is a digital circuit that performs binary addition bit by bit. The serial full adder has three single-bit inputs for the numbers to be added and the carry in. ... The carry-in signal is the previously calculated carry-out signal.
