Solution
Internet backbone may be defined by the principal data routes between large, strategically
interconnected computer networks and core routers on the Internet. These data routes are hosted
by commercial, government, academic and other high-capacity network centers, the Internet
exchange points and network access points, that exchange Internet traffic between the countries,
continents and across the oceans. Internet service providers, often Tier 1 networks, participate in
Internet backbone traffic by privately negotiated interconnection agreements, primarily governed
by the principle of settlement-free peering.
The first packet-switched computer network was the NPL network, followed closely by the
ARPANET. The latter used a backbone of routers called Interface Message Processors. Both the
NPL and ARPANET networks were interconnected in 1973, while other packet-switched
computer networks began to proliferate in the 1970s, eventually adopting TCP/IP protocols or
being replaced by newer networks. The National Science Foundation created NSFNET in 1986
by funding six networking sites using 56kbit/s interconnecting links and peering to the
ARPANET. In 1987, this new network was upgraded to 1.5Mbit/s T1 links for thirteen sites.
These sites included regional networks that in turn connected over 170 other networks. IBM,
MCI and Merit upgraded the backbone to 45Mbit/s bandwidth (T3) in 1991. The combination of
the ARPANET and NSFNET became known as the Internet. Within a few years, the dominance
of the NSFNet backbone led to the decommissioning of the redundant ARPANET infrastructure
in 1990.
The largest providers, known as tier 1 providers, have such comprehensive networks that they
never purchase transit agreements from other providers. As of 2014 there are six tier 1 providers
in the telecommunications industry. Current Tier 1 carriers include Level 3 Communications,
Telia Carrier, NTT, Cogent, GTT, and Tata Communications.
A computer network is a group of computers that use a set of common communication protocols over digital interconnections for the purpose of sharing resources located on or provided by the network nodes.
Lesson 10_ History of computer networks and the Internet.pdfraufkhalid104
The telephone network uses circuit switching to transmit information from sender to receiver – voice is transmitted at a constant speed between sender and receiver. In the early 1960s, because of the increasing importance of computers (while the cost of a computer was huge) and the advent of multitasking computers, people began to consider the problem of how to to connect computers together for sharing between users in different geographical areas.

Introduction
In the early days of computing, computers were seen as devices
for making calculations, storing data, and automating business
processes. However, as the devices evolved, it became apparent that
many of the functions of telecommunications could be integrated
into the computer. During the 1980s, many organizations began

combining their once-separate telecommunications and
information systems departments into an Information Technology
(IT) department. This ability for computers to communicate with
one another and to facilitate communication between individuals
and groups has had a major impact on the growth of computing over
the past several decades.
Computer networking began in the 1960s with the birth of the
Internet. However, while the Internet and web were evolving,
corporate networking was also taking shape in the form of local
area networks and client-server computing. The Internet went
commercial in 1994 as technologies began to pervade all areas of the
organization. Today it would be unthinkable to have a computer that
did not include communications capabilities. This chapter reviews
the different technologies that have been put in place to enable this
communications revolution.
A Brief History of the Internet
In the Beginning: ARPANET
The story of the Internet, and networking in general, can be traced
back to the late 1950s. The United States was in the depths of the
Cold War with the USSR as each nation closely watched the other
to determine which would gain a military or intelligence advantage.
In 1957, the Soviets surprised the U.S. with the launch of Sputnik,
propelling us into the space age. In response to Sputnik, the U.S.
Government created the Advanced Research Projects Agency
(ARPA), whose initial role was to ensure that the U.S. was not
surprised again. It was from ARPA, now called DARPA
((Defense Advanced Research Projects Agency), that the Internet
first sprang.

http://history.nasa.gov/sputnik
ARPA was the center of computing research in the 1960s, but
there was just one problem. Many of the computers could not
communicate with each other. In 1968 ARPA sent out a request
for proposals for a communication technology that would allow
different computers located around the country to be integrated
together into one network. Twelve companies responded to the
request, and a company named Bolt, Beranek, and Newman (BBN)
won the contract. They immediately b.

Are silenced genes associated with high or low levels of DNA methyla.pdfomarionmatzmcwill497
Are silenced genes associated with high or low levels of DNA methylation?
Solution
1.Genes are silenced by methylation(adding methyl groups). Gene silencing is the process of
turning off genes,so that it will not produce proteins through translation process.
2. Gene silencing is done by adding methyl groups to the genes. So that gene is inactive.
So we conclude that silenced genes associated with high methylation. Because when gene is
methylated only then silencing of gene occurs..

With a blow count of 14 the density of the soil is Select one 15e bitery dense. SC. Medium
Solution
solution-
if blow count is between 4 to 10 then the soil is loose, if blow count is between 10 to 30 then it
will be medium dense and if it is between 30 and 50 then it will be dense and greater than 50
means soil is very dense.
Here no of blow count is 14 it means soil is medium dense.Hence option c is correct.

Solution
1: Since lagging strand is discontinuously synthesized in form of Okazaki fragments, RNA
primer serve to form primer for synthesis of each of these fragments. So, RNA primer should be
located adjacent to the DNA pol at lagging strand.
2: DNA pol alpha serve to form RNA/DNA primers for lagging strand synthesis. These primers
are then exptended by DNA pol delta. At lagging strand, only DNA pol alpha is shown..

5. What are the properties of water? Describe each property being sure to include the following
terms: hydrophobic, hydrophilic, evaporation, cohesion, adhesion, capillarity, solvent, solute,
and solution.
Solution
(1)
Ionic bonds result when complete transfer of valence electron(s) between atoms
Example: NaCl, KCl
Covalent bonds result when valence electrons are shared between atoms.
Polar covalent bonding is a type of chemical bond where a pair of electrons is unequally shared
between two atoms: Example: HCl,
Nonpolar covalent bonds are a type of chemical bond where two atoms share a pair of electrons
with each other. Example: CCl3, H2
A hydrogen bond is the attractive force between the hydrogen attached to an electronegative
atom of one molecule and an electronegative atom of a different molecule
Example: Hydrogen bonding occurs between electronegative oxygen of water with hydrogens of
other water molecules..

NEED HELP ON C HOMEWORK
Introduction: Programmers for a Better Tomorrow
Programmers for a Better Tomorrow is an organization dedicated to helping charities, medical
societies, and scholarship organizations manage various tasks so that they can focus on making
the world a better place! They have asked you and your classmates to help them develop some
new programs to benefit their organizations.
Problem: Food Bank Management (foodbank.c)
Programmers for a Better Tomorrow is now in partnership with a local Food Bank which
distributes food items to people in need. People come in to a Food Bank and make their
donations, and others might come in to make a request for any food item they want.
A Food Bank Management Program is used to keep track of the stock the Food Bank has (i.e.,
the donations), keep a record of requests that come in, fulfilling requests and printing the status
report which consists of the amount of stock present in the food bank and the requests that are
not yet fulfilled.
The program will require you to make at least one array. You may choose to make multiple one-
dimensional arrays: one to serve as a Donations Table and one to serve as a Request Table. The
index of the array will represent the inventory type. The value in the array will represent the
amount present or needed of that type.
You may, instead, choose to combine these to two arrays into a single two-dimensional array.
There are 5 inventory types:
Protein
Dairy
Grains
Vegetables
Fruits
Your program should allow the user the following options:
Enter a Donation
Enter a Request
Fulfill Requests
Print status report
Exit
Option 1:
Ask the user for the inventory type and amount of the donation to be made. When the donation
has been added to the donations table, the program should notify the user by printing out
“Donation Added”.
Option 2:
Ask the user for the inventory type and amount of the request to be made. When the request has
been added to the requests table, the program should notify the user by printing out “Request
Added”.
Option 3:
Check each type of inventory in the Request Table.
For each item that has a value in the request table, check to see if there is inventory of the same
type in the donations table.
If there are no donations of that type, print “ requests cannot be fulfilled.” Replace with the
correct inventory type (Dairy, Fruit, etc.).
If there is some inventory in the donations table, but not enough to process all requests, print “
requests will be partially fulfilled”. Reduce both the donation and request amounts based on how
much of the request was able to be fulfilled. Replace with the correct inventory type (Dairy,
Fruit, etc.).
If there is enough inventory to fulfill the request, print “type x> requests will be fulfilled.”
Reduce the appropriate amount from the Donations Table and remove the amount from the
Request Table. Replace with the correct inventory type (Dairy, Fruit, etc.).
Option 4:
Print both tables, indicating which is for donations a.

Our understanding of genetic inheritance and the function of DNA i.pdfomarionmatzmcwill497
Our understanding of genetic inheritance and the function of DNA in producing the
characteristics of the individual have been developing for more than 150 years. Consider our
current state of knowledge. Link genetic characteristics to DNA structure. Explain how DNA
through the process of protein synthesis is responsible for the ultimate expression of the
characteristics in the organism. Describe how interference in protein synthesis can result in
disruption of cellular and bodily processes? How does the significance of one class of proteins,
the enzymes, relate to the importance of proper nutrition throughout life?

Solution
1.The gene encoding the production of protein is transcribed into the gene language required for
the next stage which is RNA. The RNA is then transcribed into protein for protection or the
function assigned. This is a simple illustration of how DNA can regulate expression of
characteristics.There are 2 parts to this process:translation and transcription.The gene for a
particular trait undergoes a process called transcription. This is a process in which the language
of the body\'s make-up is transcribed from one cell language to another (DNA to RNA) which
the body will recognize in order to carry out the next process. The next process is the translation
of the information from RNA to the actual product, which is the protein. Specific proteins play
specific roles so the body synthesizes the specific protein for the specific job at the specific time.
2.Errors in protein synthesis disrupt cellular fitness, cause disease phenotypes, and shape gene
and genome evolution.errors in protein synthesis reduce organism fitness: disruption of
translational fidelity with common antibiotics such as streptomycin and kanamycin kills bacteria;
cells with impaired translational proofreading ability display altered morphologies and suffer
severe fitness defects, as do cells with elevated rates of transcription errors in an essential gene;
defects in translational fidelity and in protein folding cause disease phenotypes in mouse
models.Synthesis and degradation of non-functional proteins may also be costly without being
obviously harmful. Ribosomal throughput dedicated to a polypeptide that will ultimately fail to
function represents an opportunity cost, particularly for fast-growing organisms. Expression of

Please Explain. Compute the worst case time complexity of the following algorithm. for i = n to
2n do for j = i - n to n do print (i, j).
Solution
for i=n to 2n do
for j=i-n to n do
print (i, j)
Here we have two loops:
1. outer for loop: runs for i=n to 2n : n times
2. inner for loop:
for each value of i, it run :
0 to n
1 to n
2 to n
.......
.......
n-1 to n
n to n
So, T(n): n + (n-1) + (n-2)+ .......+1
= n(n+1)/2

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

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.

Conduct research on Internet BackboneInternet infrastructure by sel.pdf
1. Conduct research on Internet Backbone/Internet infrastructure by selecting a Tier-1 network
(such as ATT, Verizon, Comcast, Level 3), an IXP, or a submarine communication cable;
studying its history, current status, map, provided services, and/or wellknown customers. More
Information is better!
Solution
Internet backbone may be defined by the principal data routes between large, strategically
interconnected computer networks and core routers on the Internet. These data routes are hosted
by commercial, government, academic and other high-capacity network centers, the Internet
exchange points and network access points, that exchange Internet traffic between the countries,
continents and across the oceans. Internet service providers, often Tier 1 networks, participate in
Internet backbone traffic by privately negotiated interconnection agreements, primarily governed
by the principle of settlement-free peering.
The first packet-switched computer network was the NPL network, followed closely by the
ARPANET. The latter used a backbone of routers called Interface Message Processors. Both the
NPL and ARPANET networks were interconnected in 1973, while other packet-switched
computer networks began to proliferate in the 1970s, eventually adopting TCP/IP protocols or
being replaced by newer networks. The National Science Foundation created NSFNET in 1986
by funding six networking sites using 56kbit/s interconnecting links and peering to the
ARPANET. In 1987, this new network was upgraded to 1.5Mbit/s T1 links for thirteen sites.
These sites included regional networks that in turn connected over 170 other networks. IBM,
MCI and Merit upgraded the backbone to 45Mbit/s bandwidth (T3) in 1991. The combination of
the ARPANET and NSFNET became known as the Internet. Within a few years, the dominance
of the NSFNet backbone led to the decommissioning of the redundant ARPANET infrastructure
in 1990.
The largest providers, known as tier 1 providers, have such comprehensive networks that they
never purchase transit agreements from other providers. As of 2014 there are six tier 1 providers
in the telecommunications industry. Current Tier 1 carriers include Level 3 Communications,
Telia Carrier, NTT, Cogent, GTT, and Tata Communications
