Ram=RAMDOM Access Memory, example your memory ram stick/s when you turn off or reset your PC everything stored there will be lose because it only keep temporal information while is on.
Rom= READ Only Memory, example your Hard Drive, here is where you store all your info for a later use if you want and once stored the PC can be shut down and you still will have everything if you saved it when you turn back on your PC.

Random Access Memory (RAM) can have some of your own information saved to it. Read-Only Memory (ROM) cannot have any information saved to it as it has its own information. For example: CD - ROM

When buying a computer should you be concerned about ROM or RAM?
When purchasing a computer, you need only be concerned with the RAM. All computers have ROM, but for the most part, the type or amount of it will make no impact on any aspect of the computer's operation. Since no applications you run are going to rely on ROM for storage, that leaves only RAM.
What are the main differences between ROM and RAM?
RAM is random access memory which can be written to and read. ROM is read only memory which is programmed to do a specific job, it can not be edited after it has been burnt ROM-- When viewing on a computer, Read Only Memory is information you can read and cannot click or cannot make it operable. It is not accessible. RAM--When viewing on a computer, Random Access Memory is information you can access and you can click and you can make it operable. It is accessible.
What are the examples of internal memory?

Did any PCs works without hard drive?
yes,the early PC's like oric1 and zx spectrum worked on what was called ROM and ram, the ROM was the operating system and the ram held the information for your program. data was saved on cassette tapes because usually when the machine was turned off anything in the ram dissappeared.
Where and why ROM and RAM is used?
ROM (Read-only memory) is storage used in the older computers. It can not be modified or changed in any way. It is mainly used to distribute firmware. RAM (Random-access memory) is a form of storage data, which most modern computers use. RAM can be bought in strips and slot into computers circuit boards.
How much RAM and ROM?
This laptop comes equipped with 2 GB of PC1066 DDR2 RAM. As for ROM, that's hard to say; you'd have to add-up the SRAM modules off each of its individual components and whatever disk is in the optical drive. The answer doesn't have any bearing on performance or ability, however, since by definition, ROM is read-only.
What is the definition and difference between ram rom and cache memory?
ROM (read only memory): It is the part of memory in which the data or the software related to the hardware is stored which is not to be changed frequently..Athought the EPROM and EEPROM available now in the market have the ability to be changed easily..RAM (Random Access Memory): It is the part of memory in which the data can be accesed fast and at random and the continuous movement of the storage is not necessary. like CD and dvds.. it is fast but the volatile since the data stored in it is erased after the system is powered off.Cache memory: It is the part of memory in which the data from different intermediate calculations or processes is stored where the original data is expensive to fetch...
Will ROM be erased if you lose power?
ROM, is Read Only Memory. It is a secure chip on which the manufacturers have burned data the computer needs in order to boot up the Operating System. It is not affected on losing power. RAM, on the other-hand, is Random Access Memory, and is very volatile, losing any data held in memory on powering down.
