Boolean Algebra and its Types

Introduction to Boolean Algebra Boolean algebra was developed by George Boole in 1854. He developed an algebra that was used for designing logic circuits in computer system. According to George Boole symbols can be used to represent the structure of logic in computer arithmetic. It also deals with law or rules that’s why it is also known as laws of Boolean algebra. It is used to simplify Boolean expressions which represent combinational logic circuits in computer system. The law of Boolean algebra is used to reduce and simplify a complex Boolean expression and reduce the number of gates required. The variables used in Boolean algebra have truth values such as true and false and logic values such as logic 0 and logic 1. It used with binary operation such as multiplication (.), addition (+) and unary operation (‘) . There are various types of laws of Boolean...

Logic Family and its types

Introduction to Logic family In logic family the switching characteristics of the semiconductor device such as diode, CMOS, transistor and MOSFET all are involve in the operation of digital circuit. There are various types of digital circuit are combined in a single chip or integrated circuit known as digital Integrated circuits or Digital Ics. The Digital Integrated circuits are required to make digital system or whole system. The term Integrated circuits means electronic circuit constructed on a single chip by use of such type of semiconductor devices and group of circuit give specific circuit called logic family. The Integrated circuit has small size and it is more reliable, inexpensive than other circuits.  Logic family is defined in one line that circuit arrangement or configuration of circuit element in a special manner is called logic family. Types of Logic Family The logic family can be classified...

Memory Management and its Technique

Definition of Memory Management The term Memory management means managing computer memory. In other words it provides a way to keep track of allocate portions of memory to programs at their request, and freeing it for reuse when no longer needed. It is the functionality of an operating system which handles or manages primary memory and check how much memory is required to be allocated to processes. It also keep track of some memory gets freed or unallocated and correspondingly it updates the status. It provides protection by using two registers, a base register and a limit register. The base register is used to hold the smallest legal physical memory address. The limit register is used to specifies the size of the range. For example, if the base register holds 30000 and the limit register is 120900, then the program can legally access all addresses from 30000 through...
