The document discusses different types of network topologies including point-to-point, bus, star, ring, mesh, tree and hybrid. It provides details on point-to-point, bus and star topologies. Point-to-point topology connects two computers directly in close proximity. Bus topology uses one main cable that connects all nodes and if it breaks the whole network fails. Star topology connects each computer to a central hub allowing for easier troubleshooting than bus topology.

Concept of data communication and Network TypesToufiqueAhmed13
This slide design for specially beginners. after successful completion of this slide, you will be familiar about basic concept of data communication and Network types. you can find basic concept of all about Communication.
A network is a set of devices (often referred to as nodes) connected by communication links. A node can be a computer, printer, or any other device capable of sending and/or receiving data generated by other nodes on the network.
“Computer network’’ to mean a collection of autonomous computers interconnected by a single technology. Two computers are said to be interconnected if they are able to exchange information.
The connection need not be via a copper wire; fiber optics, microwaves, infrared, and communication satellites can also be used.
Networks come in many sizes, shapes and forms, as we will see later. They are usually connected together to make larger networks, with the Internet being the most well- known example of a network of networks.
There is considerable confusion in the literature between a computer network and a distributed system. The key distinction is that in a distributed system, a collection of independent computers appears to its users as a single coherent system. Usually, it has a single model or paradigm that it presents to the users. Often a layer of software on top of the operating system, called middleware, is responsible for implementing this model. A well-known example of a distributed system is the World Wide Web. It runs on top of the Internet and presents a model in which everything looks like a document (Web page).
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.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Network Topology
1. Network Topology
Computers in a network have to be connected in some logical manner. The layout pattern of the
interconnections between computers in a network is called network topology. You can think of
topology as the virtual shape or structure of the network. Network topology is also referred to as
'network architecture.'
Devices on the network are referred to as 'nodes.' The most common nodes are computers and
peripheral devices. Network topology is illustrated by showing these nodes and their connections
using cables. There are a number of different types of network topologies, including point-to-
point, bus, star, ring, mesh, tree and hybrid. Let's review these main types.
Point-to-Point
Point-to-point topology is the simplest of all the network topologies. The network consists of a
direct link between two computers. This is faster and more reliable than other types of
connections since there is a direct connection. The disadvantage is that it can only be used for
small areas where computers are in close proximity.
Bus
Bus topology uses one main cable to which all nodes are directly connected. The main cable acts
as a backbone for the network. One of the computers in the network typically acts as the
computer server. The first advantage of bus topology is that it is easy to connect a computer or
peripheral device. The second advantage is that the cable requirements are relatively small,
resulting in lower cost.
One of the disadvantages is that if the main cable breaks, the entire network goes down. This
type of network is also difficult to troubleshoot. For these reasons, this type of topology is not
used for large networks, such as those covering an entire building.
Star
In star topology, each computer is connected to a central hub using a point-to-point connection.
The central hub can be a computer server that manages the network, or it can be a much simpler
device that only makes the connections between computers over the network possible.
2. Transmission mode refers to the mechanism of transferring of data between two devices
connected over a network. It is also called Communication Mode. These modes direct the
direction of flow of information. There are three types of transmission modes. They are:
1. Simplex Mode
2. Half duplex Mode
3. Full duplex Mode
4. Simplex Mode
n this type of transmission mode, data can be sent only in one direction i.e. communication is
unidirectional. We cannot send a message back to the sender. Unidirectional communication is
done in Simplex Systems where we just need to send a command/signal, and do not expect any
response back.
Examples of simplex Mode are loudspeakers, television broadcasting, television and remote,
keyboard and monitor etc.
Half duplex
Half-duplex datatransmissionmeansthatdatacan be transmittedinbothdirectionsona signal carrier,
but notat the same time.
Full duplex
In full duplex system we can send data in both the directions as it is bidirectional at the same
time in other words, data can be sent in both directions simultaneously.
Example of Full Duplex is a Telephone Network in which there is communication between two
persons by a telephone line, using which both can talk and listen at the same time.
3. Data communication is a process of transferring data electronically from one place to another.
Data can be transferred by using different medium. The basic components of data
communications are as follows:
1. Message
2. Sender
3. Receiver
4. Medium/ communication channel
5. Encoder and decoder
6. protocol

3. Receiver:
The device that receives the data that was sent by the Sender is the Receiver. A receiver can again be a
computer, cell phone, video camera and so on.
4. Transmission medium:

the Sender. Receiver receives the data at one end of this path and the sender sentfrom another endof
the path. Transmission medium could be like twisted-pair cable, coaxial cable, fiber-optic cable etc.

1. Personal Area Network (PAN)
The smallest and most basic type of network, a PAN is made up of a wireless modem, a
computer or two, phones, printers, tablets, etc., and revolves around one person in one building.
These types of networks are typically found in small offices or residences, and are managed by
one person or organization from a single device.
2. Local Area Network (LAN)
We’re confident that you’ve heard of these types of networks before – LANs are the most
frequently discussed networks, one of the most common, one of the most original and one of the
simplest types of networks. LANs connect groups of computers and low-voltage devices together
across short distances (within a building or between a group of two or three buildings in close
5. proximity to each other) to share information and resources. Enterprises typically manage and
maintain LANs.
6. Wide Area Network (WAN)
Slightly more complex than a LAN, a WAN connects computers together across longer physical
distances. This allows computers and low-voltage devices to be remotely connected to each other
over one large network to communicate even when they’re miles apart.
E mail
Electronicmail (email or e-mail) isa method of exchangingmessages("mail")betweenpeople using
electronicdevices.Inventedby RayTomlinson,email firstenteredlimiteduse inthe 1960s and by the
mid-1970s had takenthe formnow recognizedasemail.Email operatesacross computernetworks,
whichtodayis primarilythe Internet.Some earlyemail systemsrequiredthe authorandthe recipientto
bothbe online atthe same time,incommonwith instantmessaging.Today'semailsystemsare based
on a store-and-forwardmodel.
ftp
File Transfer Protocol, is an Internet utility software used to uploaded and download files. It
gives access to directories or folders on remote computers and allows software, data and text
files to be transfer between different kinds of computers. FTP works on the basis of same
principle as that of Client/ Server. FTP “Client” is a program running on your computer that
enables you to communicate with remote computers.
telnet is a protocol used on the Internet or local area network to provide a bidirectional
interactive text-oriented communication facility using a virtual terminal connection. User data is
interspersed in-band with Telnet control information in an 8-bit byte oriented data connection
over the Transmission Control Protocol (TCP).
Telnet was developed in 1969 beginning with RFC 15, extended in RFC 855, and standardized
as Internet Engineering Task Force (IETF) Internet Standard STD 8, one of the first Internet
standards. The name stands for "teletype network".[1
