JiniArchitecture Overview
Jim Waldo
A Jini system is a Javacentric distributed system designed for simplicity,
flexibility, and federation. The Jini architecture provides mechanisms for machines
or programs to enter into a federation where each machine o

Introduction:
Although binary data is the most efficient
storage scheme; every bit pattern represents a
unique, valid value. However, some applications

Subtraction with complement is done
with binary numbers in a similar way.

Points to remember
When using Booth's Algorithm:
You will need twice as many bits in your
product as you have in your original two
operands.
The leftmost bit of your operands (both
your multiplicand and multiplier) is a SIGN

Bezier Curves
Bezier curves are used in computer graphics to produce parametric curves which
appear reasonably smooth at all scales
The cubic Bezier curve require four sample points, the
