This document provides an overview of key concepts in computer networks and communication. It defines what a network is, discusses the need for networking and sharing of resources, and outlines the evolution of early networks like ARPANET and NSFNET into the modern Internet. It also covers network topologies, transmission media, switching techniques, common network devices, and communication protocols.
A computer network is defined as the interconnection of two or more computers. It is done to enable the computers to communicate and share available resources.

Transmission media (data communication)Pritom Chaki
Transmission media is the material pathway that connects computers, different kinds of devices and people on a network. It can be compared to a superhighway carrying lots of information. Transmission media uses cables or electromagnetic signals to transmit data.

Types of protocol
Transmission control protocol (TCP)
internet protocol (IP)
Hyper text transfer protocol (HTTP)
Simple mail transfer protocol (SMTP)
File transfer protocol (FTP)
Layers
protocol:-A protocol is a set of rules for the exchange of data between a terminal and computer or between two computers. Think of protocol as a sort of recommunication agreement about the form in which a message or data is to be sent and receipt is to be acknowledge.
transmission control protocol(TCP):-This protocol ensures the delivery of information packets across network.
internet protocol (IP):-This important protocol is responsible for providing logical addressing called IP address to route information between networks.
hyper text transfer protocol (HTTP):- This protocol is used to access, send and receive Hypertext Markup Language (HTML) files on the Internet.
simple mail transfer protocol(SMTP):-This protocol is used for transferring email between computers.
file transfer protocol(FTP):-FTP is responsible for allowing file to be copied between devices.
layers:-In computer programming, layering is the organization of programming into separate functional components that interact in some sequential and hierarchical way, with each layer usually having an interface only to the layer above it and the layer below it.

Network Plus study guide.
Covers the basic with point form answers and easy to remember.
Those who hold a Network+ certification may improve their chances of landing a job in the networking industry or increasing salary in their existing position. A Network+ also can be used to partially satisfy some prerequisites of more advanced IT certifications. For example, it qualifies as one of part of the elective exam requirement of the Microsoft Certified Systems Administrator (MCSA) certification.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

36. Star topology A star topology is designed with each node (file server, workstations, and peripherals) connected directly to a central network hub or concentrator Data on a star network passes through the hub or concentrator before continuing to its destination. The hub or concentrator manages and controls all functions of the network. It also acts as a repeater for the data flow.
