ROM- Read only memory is a storage media used in computers as well as in many electronic devices. Unlike RAM the data stored in ROM cannot be modified and hence it is used to deal out firmware. Firmware is nothing but software which doesn’t need regular updates.
ROM stores data which cannot be modified but modern day ROMs such as EPROM and EEPROM can be wiped out and reenter data for multiple times. Even though the data here can be erased and reentered they too are called as ROM because the reprogramming process is generally slow and not frequent.
Five basic types of ROM are ROM, PROM, EPROM, EEPROM, and FLASH MEMORY. Each one of them has matchless characteristics, but also two things in common. The data stored here is not removed when power is off and unlike RAM, the data in the chip is either unchangeable or it can be changed through special operation.

The hot topic that is being discussed among people nowadays is about the environment. What are the industries doing to stop pollution, more pollution created by the growing technologies and about paper recycling are the points that people generally talk about. We people have to find solution regarding these environmental issues to lead a life without any problem.
The three main source of pollution are water, air, and waste pollution. The one that is most dangerous and affect human health directly is air pollution. The countries with more population are generally affected by this air pollution. It is caused by the factory emanation and by the auto emissions.
The auto emissions can be reduced by searching for alternative fuels. The alternative fuel that is available currently is electricity which can be used in the form of solar energy. The pollution caused by the air, totally damages the human ecosystem and so steps have to be taken as early as possible to stop this issue.
