Microprocessor Registers, AGP, and CardBus Explained
AGP (Accelerated Graphics Port)
AGP (Accelerated Graphics Port) included three performance-enhancing features:
- Pipelined memory read/write operations.
- Demultiplexing of the data and address bus.
- Increased speed up to 100 MHz (providing a throughput over 800 MB/s, more than four times that of PCI).
CardBus Interface
CardBus devices are 32-bit and based on the 33 MHz PCI bus (unlike PC Cards, which can be 16 or 32-bit). CardBus includes bus mastering, enabling communication between the controller and connected

Normalization
Normalization consists of evaluating and correcting table structures to minimize data redundancies, reducing data anomalies, and assigning attributes to tables based on determinants. It involves applying formal normal forms (1NF, 2NF, 3NF). Higher normal forms (NF) are generally preferred over lower normal forms.
Normalization is best performed early in the overall design process, for example, when designing a new database structure.

Java Code Examples
Matrix Operations
import java.util.Scanner;
// Class for matrix operations
class MatrixOperations {
// Addition of two matrices
public static int[][] addMatrices(int[][] matrix1, int[][] matrix2) {
int rows = matrix1.length;
int cols = matrix1[0].length;
int[][] result = new int[rows][cols];
for (int i = 0; i < rows; i++) {
for (int j = 0; j < cols; j++) {
result[i][j] = matrix1[
Microprocessor Systems: Architecture and Components
Microprocessor System
A microprocessor system is the core of a computer. It is formed by a microprocessor: an integrated circuit that contains all the elements of the Central Processing Unit (CPU). Its functions are:
- Executes arithmetic instructions contained in the programs.
- Performs arithmetic and logical operations necessary for data processing.
- Centralizes control of the machine and exchanges data with main memory.
There are 4 different models of Microprocessors: Intelligence, ANP, and AIM.

Types of Communications
If a link between two nodes can be selected for communication in both directions (but alternatively), the link is bidirectional. If it is set in one direction and under the terms of a node, it will be one-way (incoming or outgoing).
- If a user node wants to communicate with another user and it also belongs to the node, the switching system has to make the connection of both. This communication is called local communication.
- If the user wishes to establish communication with another
