Body Computer: Summary

A computer is an electronic device that stores and processes data and is capable of operating other devices. The operation of the computer is divided into four basic functions: input, processing, storage, and output. Binary numbers are represented by the numbers 1 and 0. A transistor that operates as a relay is the basis of

Outputs

Once the computer’s programming instructs that a correction or adjustment must be made in the controlled system, an output signal is sent to an actuator. This involves translating the electronic signals into mechanical motion. An output driver is used within the computer to control the actuators. The circuit driver usually applies the ground circuit of

Information Processing

The air charge temperature (ACT) sensor input will be used as an example of how the computer processes information. If the air temperature is low, the air is denser and contains more oxygen per cubic foot. Warmer air is less dense and therefore contains less oxygen per cubic foot. The cold, dense air requires more

Computer Memory

The computer requires a means of storing both permanent and temporary memory. The memories contain many different locations. These locations can be compared to file folders in a filing cabinet, with each location containing one piece of information. An address is assigned to each memory location. This address may be compared to the lettering or

Microprocessor

FIGURE. Main components of the computer and the Microprocessor. The microprocessor is the brain of the computer. The microprocessor is constructed of thousands of transistors that are placed on a small chip. The microprocessor brings information into and out of the computer’s memory. Hie input information is processed in the microprocessor and checked against the

Analog and Digital Principles

Remembering the basics of electricity, voltage does not flow through a conductor; current flows and voltage is the pressure that “pushes” the current. However, voltage can be used as a signal; for example, difference in voltage levels, frequency of change, or switching from positive to negative values can be used as a signal. The computer

Computer Functions

A computer processes the physical conditions that represent information (data). Hie operation of the computer is divided into four basic functions: Input: A voltage signal sent from an input device. This device can be a sensor or a switch activated by the driver or technician. Processing: The computer uses the input information and compares it
