What is d use of ROM in computer?
I know dt ROM is used during BootUp bt I wana to HUB memebers to plz give short explanative description?
Secondly,I want to ask that If there is no Rom in computer dn what will happen?
ROM- Read Only Memory. The CPU cannot easily write information into ROM, it is generally programmed upon manufacture with particular data. A program will be stored on ROM, the CPU will read ROM and carry out tasks dictated by the data it reads.
Think of it as making a meal in the kitchen. You're ROM (Hard Drive) would be the cabinet in this scenario. Sure it holds a lot, but it takes a while to get to. Ram is like your counter, you may not be able to store as much crap there, but it's a lot faster to get to.
Let's say you wanna make some food (or do an action on your computer), first you take out of the cabinets (the HD is read) then it's loaded into the RAM (Random Access Memory) which is a lot faster to get to, then it will be processed.
If you had no ROM on your computer technically it wouldn't boot up, it wouldn't even post. Your harddrive is rom, but technically the CMOS has ROM on it as well, which stores the BIOS data.

I find when I try and read a Hub from my iPhone, it won't load. I wonder if that is because the Hub is too long, or has too many photos. I give up until I can get to my computer.Seems I read (or maybe dreamed) our Hubs should be shorter to be easier to load from a mobile phone.Any...
