This presentation contains why we need sub netting, how we do sub netting, CIDR, Subnet mask, Subnet mask value, Class A Sub netting, Class B Sub netting, Class C Sub netting.
IP Addressing and Subnetting
1. Write the default Masks for the Class A, Class B and Class C IP addresses.
2. How we can distinguish Class A, Class B, Class C, Class D and Class E IP addresses from each other. Write the range of first octet in decimal and Binary for all the 5 IP address classes.
3. Write the default subnet Masks for the following IP addresses:
4. Write down the three available ranges for assigning Private IP addresses recommended by IANA (Internet Assigned Number Authority).
5. A broadcast address is the one that addresses to all the hosts in any network. State that to create a broadcast address, all the bits of network ID portion or all the bits of host ID portion are set to 1? Write down the broadcast addresses of the networks to which the following IP addresses belong, write network addresses and ranges of their valid IP address too. (No subnetting).
6. Subnet Mask or Custom mask tells us that how many bits are used for Subnet ID portion and how many for host ID portion. Identify how many bits are used for sub netting in the following IP address using its subnet mask:
7. Extract the Network Addresses of the given IP addresses in question number 8, using the subnet masks given with them. (Remember that ANDing the IP address with the Mask extracts the network address from the given IP address).
8. Suppose you have a class C Network 208.94.115.0. Your task is to design a subnet scheme so that we can create 16 Network segments (subnets) within this Network. Each subnet should support 10-14 hosts.
9. Suppose you have a class C Network 220.94.115.0. Your task is to design a subnet scheme so that we can create 28 Network segments (subnets) within this Network. Each subnet should support hosts as given below.
• 2 Network Segment support 30 Hosts
• 4 Network Segment support 14 Hosts
• 8 Network Segment support 6 Hosts
• 14 Network Segment support 2 Hosts

An IP addresses an identifier for a particular machine on a particular network.
IP stands for Internet Protocol.
IP works at network layer of OSI model.
The network portion of the IP Address is allocated by the internet service provider(ISP) under authority of the Internet Assigned Number Authority(IANA).
There are two main types of IP Addresses.
IPv4
IPv6
Which section of the IP Addresses represent the network and which section represent the machine will depend on what ‘class’ of the ip address is assigned to a network.
Without IP Address devices on different networks will not be able to communicate.
Every device needs an IP address in order to communicate(connect) to the internet.
This presentation gives a brief description about IP Address (Internet protocol address), Classes of IPv4. And also included, what is IPv4 and what is IPv6.

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 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.

2. What is ip address?
❏ An IP Address is an identifier for a particular
machine on a particular network. It is part of a
scheme to identify computers on the internet.
❏ Ip address are also referred to as IP number and
internet address.
❏ The network portion of the IP address is
allocated to internet service providers (ISP) by
the InterNIC, under the authority of the internet
assigned number authority (IANA).
❏ ISP’s then assign the host portion of the IP
address to the machines on the networks that
they operate. 2
3. Which section of the IP address
represent the network & which
sections represents the machine
will depend on what “class” of IP
address is assigned to a network.

QUESTIONS?
5. IPV4
❏ It is 32 bit number represented in 4
decimal number where each decimal
number is of 8bit (octet) is separated by a
dot(.)
❏ Thus representation known as doted
decimal representation. IP address
consists of 2 components the network id
and the host id.
6. IPV4
❏ Network id:-it is the number assigned
to a network in the internet. Host id:- it
represents the id assigned to a host in
the network.
❏ IPv4 allows 232 (4294967296) unique
address which section of IP address
show the network id & which section
show the machine or host id depend on
the class network. 6
