DIALOGUE
Anton: What is the purpose of using computers on board the car?
Vlad: You see. As I know computer is used to advance the engine operation as well as the performance of other units.
A.: What components does the on-board computer consist of?
V.: It consists of two components. One is the hardware and the other is the software.
A.: What is hardware?
V.: The computer hardware uses a Central Processing Unit (CPU) which is referred to as a microprocessor.
A.: What is software?
V.: The computer software on a car carries a program. The program tells the computer what to do and when to do it.
A.: And where is the program stored?
V.: It is stored in a permanent memory which is called Read Only Memory (ROM).
A.: And what is Programmable Read Only Memory (PROM)? What is the difference between ROM and PROM?
V.: In case the memory becomes defective PROM can be readily removed and replaced, while ROM cannot.
A.: And what is RAM?
V.: RAM is Random Access Memory (main memory), which can be accessed without going through a specific sequence. The technician interfaces with RAM whenever trouble codes are accessed.
A.: Thanks a lot for your explanation.
V.: You are welcome. See you later.
A.: Goodbye.
