Description
On an Ethernet switching network, redundant links are used to implement link backup and enhance network reliability. However, the use of redundant links may produce loops, leading to broadcast storms and an unstable MAC address table. As a result, communication on the network may deteriorate or even be interrupted. To prevent loops, IEEE introduced the Spanning Tree Protocol (STP).
Devices running STP exchange STP Bridge Protocol Data Units (BPDUs) to discover loops on the network and block appropriate ports. This enables a ring topology to be trimmed into a loop-free tree topology, preventing infinite looping of packets and ensuring packet processing capabilities of devices.
IEEE introduced the Rapid Spanning Tree Protocol (RSTP) to improve the network
convergence speed.

Liquefaction of Gases
Liquefaction of Gases – Critical Phenomenon
A gas can be liquefied by lowering the temperature and increasing the pressure. At lower temperature, the gas molecules lose kinetic energy. The slow moving molecules then aggregate due to intermolecular attractions between them and are converted into liquid. The increase of pressure - The gas molecules come closer by compression and coalesce to form the liquid.

Valence Bond theory (with hybridization)
A view of chemical bonding in which bonds arise from the overlap of atomic orbitals on two atoms to give a bonding orbital of electrons localized between the bonded atoms. Basic Principle: A covalent bond forms when the orbitals of two atoms overlap and the overlap region, which is between the nuclei, is occupied by a pair of electrons.

Basic Electronics
A normal P-N junction diode is usually fabricated by adjusting the P-type and N-type semiconductors on a single semiconductor crystal. The characteristics of a junction diode demonstrate that it is designed largely for operating in the forward direction. Applying a large amount of forward bias causes greater forward current with a small value of forward voltage.

Fundamentals of Programming
Programming is the art of writing computer instructions in a language that the computer can interpret and/or understand. In this topic, we shall look at some basic definitions and introduce some basic concepts in programming.
Definition 1. A computer is an electronic machine that accepts data as its input, process these data based on some instructions to produce information as it output. These instructions that guide a computer on how to process the data is what we refer to as a program.

CLIENT/SERVER COMPUTING
Client/Server is a term used to describe a computing
model for the development of computerized systems.
This model is based on the distribution of functions
between two types of independent and autonomous
processors: servers and clients. A client is any process
that requests specific services from server processes.

HIV-Human Immune Virus
This is a virus that causes AIDS and is passed from person to person through body fluids, particularly blood, semen and breast milk .After a person has been infected, the virus starts breaking down their immune system .After sometime the immune system is so weak that they become susceptive to a variety of illness

INTER-PROCESS COMMUNICATION OR PROCESS SYNCHRONIZATION
Concurrent access to shared data may result in data
inconsistency. Maintaining data consistency requires mechanisms to ensure the orderly execution of cooperating processes. Suppose that we wanted to provide a solution to the consumer-producer problem that fills all the buffers.
