A pendrive cannot act as ram. RAM's memory is volatile and directly connected to the motherboard. A pendrive can only act as physical memory.
Add more, you cannot not speed it up, but you can improve it by adding RAM memory.
rom (Read only Memory)
it means that the memory cannot be earased
ROM: Read Only Memory, Memory that can only be read, it cannot be rewritten. RAM: Random Access Memory, it's a kind of memory that can be read and rewritten many times, it loses its information when it loses power.
Your Hard Disk is where programs and data are stored for later retrieval ( excluding virtual memory) . If a program is in execution it has to be loaded in the memory (by memory I mean the RAM), So your Java Heap has to be in the RAM and cannot reside on the Hard disk.
the function of a memory ram is to store memory that can be accessed later on.
RAM or 'memory'
RAM can be edited/modified many times, while ROM usually cannot be modified. Some ROM can be changed slightly, or reset by exposure to UV light. but most of ROM has to be sent back to the factory if there is an error with it's contents.
You most likely have an integrated video card. Integrated video cards do not have their own memory, and use system memory (RAM) for video. Your video card is using 32MB of your ram. On most computers you can change the amount available to video by logging into bios and changing video memory amount.
RAM is one of the memory... it is non volatile memory...
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.
