Many phones today come with the answering machine already built in. When a caller leaves a message, the voice becomes a stream of bytes. Inside the answering machine, there is a microcontroller that digitizes the message the caller left. An analog-to-digital converter makes the voice digital. The digital answering machine uses solid state memory storage. The digitalized message is stored in low-power RAM (Random Access Memory).

When a message is left on an answering machine and digitized into bytes of data, it is stored at a specific address in RAM. When the owner plays back his messages, the microcontroller reads the bytes from RAM and sends them through a digital-to-analog converter. Then the owner of the answering machine hears the caller's voice and message through the speakers. When the owner deletes a message, other messages are still available and will be played in order. This is because RAM is a high-speed memory device. The microcontroller moves up the other messages into freed-up space when a previous message is deleted.

Kazuo Hashimoto invented the digital answering machine in 1983. It was called the Automatic Digital Telephone Answering Device. An answering machine is also commonly referred to as an answerphone or telephone answering device (TAD). The owner records a greeting that is played when the answering machine answers a phone call, and the answering machine can be set to answer after a certain number of rings. Another common feature of digital answering machines is that the owner can remotely check his messages by calling home and keying in a code.

How does the work done a machine compare to the work done by a machine?

The work done by a machine is the output energy provided by the machine in an intended task, while the work done on a machine is the input energy required to operate the machine. The work done by the machine should ideally be greater than the work done on the machine to ensure efficiency.


What is work done on a machine called?

The work done on a machine is called input work or mechanical work. It refers to the energy transferred to the machine to operate it and perform tasks.


If the input work on a machine the machine has blank efficiency?

If the input work is processed by a machine and no output work is produced, the machine is considered to have zero efficiency. This means that the machine is not effectively converting input work into useful output work.


How does input work and out put work affect the efficiency of a simple machine?

Input work is the work done on a machine, while output work is the work done by the machine. Efficiency of a simple machine is calculated as the ratio of output work to input work. The efficiency of a simple machine is high when the output work is close to the input work, indicating that the machine is converting most of the input work into useful output work.
