Aneprom is a programmable read only memory. It can be reprogrammed many times. Takes ultraviolet rays to erase the EPROM usually minutes However on sun light ultra Violet emission will take years to completely erase it.To program the chip one pin is raised to a hi voltage and whatever data 1/0 on the input will be burned into it where it is determined by the address line. So data will be burned at whatever address is selected. This data will remain embedded until again erased.

by using a suitable diagram, explain the one of the operation in microwave energy sources except Guinn Diode.
The best way to do this is to find the diagrams. Do a quick image search to find the information that you need.
ELCB means Earth Leakage Circuit Breaker -- it is used to trip the Circuit breaker if any leakage fault occured means
Some Integrated circuits are chips that can be programmed to customiise them to a particular requirement laid down by the designer.They are now in many forms Some can be electrically programmed with binary data in the form of Hexadecimal notation or machine code. This is known as an EPROM Some newer chips can be programmed via an interpreter in a high level language.These are the new universal chips known as PICS. These have taken over as single chip controllers of microwave ovens and washing machines for example.Software can be erased and upgraded as the product develops and this is done electrically rather than having to use Ultra Violet light as in the EPROM. The chips are supplied by the manufacturer in an unprogrammed state and they are then usually placed into a PROM programmer and 'blown' by the programmer according to the binary data you have asked it to load. The programmed chip is checked and then placed into a socket on it's circuit board and is able to direct the operation of a microprocessor. PICS are treated the same way and then slotted into the target board but can be reprogrammed in situ if a software upgrade is necessary.

EPROM stands for Erasable Programmable Read Only Memory.
Cannot be universally answered, it depends on the current EPROM. It might be empty as well.
Permanent
its impossible
The advantages were "accumulative", so a history of the development of ROM is best to explain them: First came ROM - Read-Only Memory. Unlike RAM, ROM could not be written to but had the advantage that it was non-volatile which means its contents are permanently there, they do not disappear when power is removed. But the contents were put there in the factory, you could not "program" the contents yourself. Then came PROM - Programmable ROM. With PROM you could, if you owned a programming machine or "programmer", set the contents of the PROM yourself, one time, before your put it in the electronic circuit board. Next came EPROM - Eraseable PROM - with EPROM if you needed too you could take the EPROM out of the circuit board, put it in an EPROM eraser to reset the contents, and then program it again in the programmer. The EPROM eraser was a small box that the EPROM was placed inside. When the box was turned on ultra-violet light shined into the EPROM thorough a small "window" on the top of each EPROM, erasing the contents. Finally came EEPROM or E2PROM - Electronically Erasable PROM. With EEPROM you didn't need the eraser or the programmer! The EEPROM can be programmed, again and again while it is on the circuit board, by sending a sequence of signals to certain pins on the device.

CMOS, EEPROM and EPROM
Power On Self Test instructions are part of the BIOS that is stored in EPROM. Some of the parameters used by the EPROM are stored in the BIOS CMOS chip.
