Weighing in at a sturdy 397 g, the first ever Communicator was driven by an Intel 24 MHz i386 CPU. Running on the GEOS 3.0 operating system, it had a mere 8 MB of memory: Half of which was used for apps, 2 MB for program memory and 2 MB for user data. While these specs might not sound very impressive, in its day the Nokia 9000 Communicator was the best unisex could get. This is probably why it was used by Val Kilmer when he played <a href="http://www.youtube.com/watch?v=F4JOxijD1ts" style="color: #336699; word-wrap: break-word;" target="_blank">Simon Templar</a> in the 1997 remake of The Saint.</span></span></span></div><div align="left" style="background-color: white; color: #444444; font-family: OpenSansRegular; font-size: 14px; line-height: 21px; word-wrap: break-word;"><span style="font-family: Arial; word-wrap: break-word;"><span style="font-size: small; word-wrap: break-word;"><span style="color: black; word-wrap: break-word;"><br style="word-wrap: break-word;" /></span></span></span></div><div align="left" style="background-color: white; color: #444444; font-family: OpenSansRegular; font-size: 14px; line-height: 21px; word-wrap: break-word;"><div align="center" style="word-wrap: break-word;"><ignore_js_op style="word-wrap: break-word;"><img aid="279962" file="data/attachment/forum/201502/15/005307mij7hj7ab5jktl7s.jpg.thumb.jpg" id="aimg_279962" initialized="true" inpost="1" src="http://en.miui.com/data/attachment/forum/201502/15/005307mij7hj7ab5jktl7s.jpg.thumb.jpg" style="cursor: pointer; word-wrap: break-word;" zoomfile="data/attachment/forum/201502/15/005307mij7hj7ab5jktl7s.jpg" /></ignore_js_op></div></div><div align="left" style="background-color: white; color: #444444; font-family: OpenSansRegular; font-size: 14px; line-height: 21px; word-wrap: break-word;"><span style="font-family: Arial; word-wrap: break-word;"><span style="font-size: small; word-wrap: break-word;"><span style="color: black; word-wrap: break-word;"><br style="word-wrap: break-word;" /></span></span></span></div><div align="left" style="background-color: white; color: #444444; font-family: OpenSansRegular; font-size: 14px; line-height: 21px; word-wrap: break-word;"><div align="left" style="word-wrap: break-word;"><div align="left" style="word-wrap: break-word;"><span style="font-family: Arial; word-wrap: break-word;"><span style="font-size: small; word-wrap: break-word;"><span style="color: red; word-wrap: break-word;"><span style="font-weight: 700; word-wrap: break-word;">Q3- What is </span><span style="font-weight: 700; word-wrap: break-word;">difference between 32-bit processors and 64-bit processors</span><span style="font-weight: 700; word-wrap: break-word;">?</span></span></span></span></div><br style="word-wrap: break-word;" /><div align="left" style="word-wrap: break-word;"><span style="font-family: Arial; word-wrap: break-word;"><span style="font-size: small; word-wrap: break-word;"><span style="font-weight: 700; word-wrap: break-word;"><span style="color: black; word-wrap: break-word;">Ans</span>- <span style="color: black; word-wrap: break-word;"></span></span><span style="color: black; word-wrap: break-word;">A major difference between 32-bit processors and 64-bitprocessors is the maximum amount of</span><span style="color: black; word-wrap: break-word;">memory (RAM) that is supported. 32-bit computers support a maximum of 3-4GB of memory, whereas a 64-bit computer can support memory amounts over 4GB.

For example, a dual-core chip may look like a single CPU chip, but it actually has two physical central processing units on the chip.</span></span></span></div><div align="left" style="word-wrap: break-word;"><span style="font-family: Arial; word-wrap: break-word;"><span style="font-size: small; word-wrap: break-word;"><span style="color: black; word-wrap: break-word;">Additional central processing units allow a computer to do multiple things at once.
