ROM or the read only memory is basically a memory chip that stores instructions and data on permanent basis and don't even require power to work. The contents are written on the chip during the time of its manufacturing and cannot be changed thereafter. ROM is very important as far as the concept of handheld computing is concerned because in majority of the handhelds the operating system not only sometimes gets stored but executed in them too. In a typical desktop, OS is stored on its hard drive and get loaded into main memory when we boot up. This creates the need of upgrading handheld's operating system and replacing the contents of ROM each time we boot up.
