CPU ,memory,hard disk, display,mailboard
The above is partially correct. The question is actually 40+ years old and was asked of me in an engineering class back in 1968. Back then it was 'What are the 5 parts of a computer.'
Technically s computer does NOT need storage, aka a hard drive or a floppy etc to be a computer. It also doesn't need a display nor a mailboard. How mailboard got here I don't know.
It needs:
CPU (for processing commands)
Input (from a keyboard, or a floppy, a hard drive etc to input both commands and data)
Output ( to a monitor, a printer, magnetic tape, paper tape, punch cards etc)
Memory ( the place an actual program and or data that the CPU uses MUST reside)
The 5th item I alluded to is the Arithmetic Processor. The CPU proocesses the commands while the Arithmetic Processor manipulates the data to add, subtract, multiply and divide. In today's computers (post-1985) the CPU and the Arithmetic Processor are on the same chip. Previously, for those who remember the Z80 and the 8080 processors, for more "computing power" you could install an Aritmetic Processor to upgrade the PC and give the built-in arithemtic processor more capability.
it becomes communication system through networking......
The meaning of police patrol operation with police communication system is to keep an open line of communication between the station and the patrol officer. This is done through radio contact.

Typical hazards that threaten the normal operation of a computer system can range anywhere from having a virus to power outages.

The common way of communication in disaster management is the emergency communication system. This computer-based system supports one-way and two-way communication for emergency messages.
