80286 The needs of a multitasking/multiuser operating system include environment preservation during task switches‚ operating system and user protection‚ and virtual memory management. The Intel 80286 was the first 8086 family processor designed to make implementation of these features relatively easy. The 80286 was used as the CPU in the IBM PC/AT and its clones‚ in the IBM PS/2 Model 50‚ and in the IBM PS/1. As you can see in the block diagram in Figure 5.2‚ an 80286 contains four separate

Simulation model in MATLAB Following is the methodology of simulation of the QAM modulator in MATLAB‚ 1) Generation of random binary sequence‚ this is the input which is to be modulated. 2) Assigning group of 4 bits to each 16-QAM constellation symbol per the Gray mapping 3) Addition of white Gaussian Noise 4) Demodulation of 16-QAM symbols Upon reception of the signal‚ the demodulator

C H A P T E R I ALL ABOUT Java.lang PACKAGE Discussions String A String is a series of characters‚ example [‘h’‚’e’‚’l’‚’l’‚’o’]. In Java‚ string is an object. The Java platform has String class to create and manipulate strings in a Java application. To create a string‚ write String remark = “This is it!”; In the above statement‚ “This is it!” is a string literal‚ a series of characters. This string literal is assigned to a String object named remark. The string literal

be held as either a character‚ an integer or even a real. If any calculations are going to take place on the value then it should be held as either an integer or a real. If the calculation will never result in it being extremely large or gaining decimal places then an integer should be used. 4. Boolean A boolean can only be one of two values‚ either true or false. A boolean only really needs one bit (an eighth of a byte) to hold true (1) or false (0) but strangely‚ Visual Basic uses two bytes

Boolean Functions - Computer Organization (IT 25) BOOLEAN FUNCTIONS A Boolean function consists of a binary variable denoting the function‚ an equals sign and an algebraic expressions formed by using binary variables the constants 0 and 1‚ the logic operation symbols‚ and parentheses. For a given value of the binary variables‚ Boolean function can be equal to either 1 or 0. Example: F = X + Y’Z The two parts of the expression X and Y’Z‚ are called terms of the function F.
