A USB flash drive is a data storage device that includes flash memory with an integratedUniversal Serial Bus (USB) interface. USB flash drives are typically removable and rewritable‚ and physically much smaller than a floppy disk. Most weigh less than 30 g.[1] As of September 2011 drives of 256 gigabytes (GB) are available‚[2] Storage capacities as large as 2 terabytesare planned‚ with steady improvements in size and price per capacity expected.[3] Some allow up to 100‚000 write/erase cycles‚ depending

Parallel Computing In India Introduction to Parallel Computing Traditionally‚ software has been written for serial computation: • To be run on a single computer having a single Central Processing Unit (CPU); • A problem is broken into a discrete series of instructions. • Instructions are executed one after another. • Only one instruction may execute at any moment in time. In the simplest sense‚ parallel computing is the simultaneous use of multiple compute resources to solve

ABSTRACT A Java Ring is a finger ring that contains a small microprocessor with built-in capabilities for the user‚ a sort of smart card that is wearable on a finger. Sun Micro system s Java Ring was introduced at their Java One Conference in 1998 and‚ instead of a gemstone‚ contained an inexpensive microprocessor in a stainless-steel iButton running a Java virtual machine and preloaded with applets (little application programs). The rings
