Data Link Layer Fundamentals
The Data Link layer provides the means to exchange data over common local media. It performs two basic services:
- Allows higher layers to access the media using techniques such as framing.
- Controls how data is placed onto and received from the media using techniques such as media access control.
Layer 2 Terminology
- Frame: The Protocol Data Unit (PDU) of the Data Link layer.
- Node: A Layer 2 notation for network devices connected to a common medium.

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.
Potential Issues Leading to Low Normal Forms

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.
