Extensible Markup Language (XML)

Extensible Markup Language (XML) is a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. XML is  much like HTML but HTML is designed to display data where as XML is designed to store and transport data. Tags in XML are not predefined as in HTML. We can define our own tags.

SAP-1(Simple as Possible-1) Computer Architecture Introduction

The Simple-As-Possible (SAP)-1 computer is a very basic model of a microprocessor explained by Albert Paul Malvino. The SAP-1 design contains the basic necessities for a functional Microprocessor. Its primary purpose is to develop a basic understanding of how a microprocessor works, interacts with memory and other parts of the system like input and output. The instruction set is very limited and is simple. The features in SAP-1 computer are: W bus – A single 8 bit bus for address and data transfer.  16 Bytes memory (RAM)  Registers are accumulator and B-register each of 8 bits.  Program counter – initializes from 0000 to 1111 during program execution.  Memory Address Register (MAR) to store memory addresses.  Adder/ Subtracter for addition and subtraction instructions.  A Control Unit  A Simple Output.  6 machine state reserved for each instruction  The instruction format of SAP-1 Computer is (XXXX) (XXXX) A Simple animation to demonstrate the working of SAP I:
