1. Attorney Client Privilege
The interesting part of the two matters I will be addressing here is that an individual almost has to
know prior to a suit being filed that litigation may occur. Discussions and written matter, all
correspondence, emails and documents exchanged between parties should be prepared with a
thought to potential litigation. Attorney Client Privilege and the Work Product Doctrine are two
separate and distinct issues and should be treated within the legal world as separate disclosures.
Attorney Client Privilege, which originated in Roman and canon law, has evolved into a recognized
judicial doctrine and is necessary in order to provide clients with access to effective, well informed
counsel. In Upjohn Co. v US the Supreme Court the Court ... Show more content on Helpwriting.net

Prior to a corporation or its employees taking action, it usually requires an informed legal advice.
Legal direction may be either taken or dismissed; the point is that in order to provide an informed
decision counsel and its direct reports are provided with confidential information. Counsel reviews
the confidential information and provides an opinion on the issue. This opinion may or may not
support the legality of a matter and the company may or may not act because of the information
provided, however, the confidentiality of the initial information provided, the attorney's thought
process, as well as all reasoning associated with this process needed to be retained as confidential.
Particularly when a corporation has in–house counsel, counsel may wear two hats. Not only is the
counsel required to provide legal information, some with expert business sense, is asked to provide
operational and directional advice. Corporate counsel usually holds more than one title; (in addition
to those of General Counsel, Corporate Counsel, Associate Corporate Counsel, etc.) they may also
hold the title of an Officer of the company (e.g. Executive Vice President, Senior Vice President,
Vice President, Secretary, etc.) Counsel needs to be able to separate these titles to ensure that the

In addition, it is advisable to have a performance budget. Performance budget determines the limit
on the page load speed and the size of the requests. It should address if there are more elements to
accommodate how to handle it.
Page Optimization
Minifying the elements
CSS, Images, and JS files are the core elements for the better performance. Minifying the CSS,
Images, and JS files will leads to huge performance improvement. E.g. if the website built on
WordPress framework, there would be many of number of CSS, Images, and JS files scattered
across various location. This would lead to more time to load in the devices.
However, by integrating all the files into one single location, user can feel better load time. It will
reduce the number of requests sent from client to browser.
Page Size
Also, size of the each request matters for the performance. Assume that if the end user bandwidth is
256KB per second, if the number requests' size is 1 MB then the load time will be at least 4 seconds.
If there is a poor network, then the load time will be more than 4 seconds. Therefore, it is ideal to
have minimum number of requests with less size.
Image format

5. Client Attorney Privilege : The Code Of Silence
Client attorney privilege is describes the code of silence that is a legally recognized right of the
client to tell his attorney anything and the attorney will can not disclose this privileged
communication.
However, in some cases it 's sad that you as the attorney have to refer to the code of silence in order
not to be disbarred. I know I would want to give that mother of the five years boy some closure and
stop the argany with the hopes that her five year old is still alive.
I also understand the reasoning behind not disclosing information about the child 's remains..
According Banks, 2013, because the boy is already dead and could not be help, however on the
other hand if the lawyer had discovered the boy alive and wounded but still alive , the lawyer would
have to say something to prevent any further harm to the child. Then this rule wouldn 't have apply.
Morally it 's not a good feeling on he attorney part about knowing that a child life has been taken
and the grieving mother still has hope that her child is still alive. More so the attorney knows the
facts about the child death and has to hold to the code of silences. Another fact is client privilege is a
right for the client not the attorney . This was put into place so a client can feel free to tell his
attorney anything and it not be used against him or her in a court of law.
Pollack , 2010, states that many lawyers believed that loyalty to the client is paramount to their
duties as a professional. This is

BENEFITS OF USING CLOUD COMPUTING IN E–LEARNING
One of the most interesting applications of cloud computing is educational cloud. The educational
cloud computing can focus the power of thousands of computers on one problem, allowing
researchers search and find models and make discoveries faster than ever. The universities can also
open their technology infrastructures to private, public sectors for research advancements. The
efficiencies of cloud computing can help universities keep pace with ever–growing resource
requirements and energy costs. Students expect their personal mobile devices to connect to campus
services for education. Faculty members are asking for efficient access and flexibility when
integrating technology into their classes. Researchers want instant access to high performance
computing services, without them responsibility of managing a large server and storage farm. The
role of cloud computing at university education should not be underestimated as it can provide
important gains in offering direct access to a wide range of different academic resources, research
applications and educational tools. Usually, E–learning systems are developed as distributed
applications, but not limited to. The architecture of an e–learning system, developed as a distributed
application, includes a client application, an application server and a database server, beside the
hardware to support it (client computer, communication infrastructure and servers).

An assumption that is intrinsic to a basic communication involves two parties, the server and the

administrator and has got control over all other clients who wish to join the network.
BRIEF OVERVIEW OF THE DESIGN: The Multicasting in java can be achieved by using the

to receive messages from each ... Show more content on Helpwriting.net ...
Once the user logs into the system with his/her credentials provided the server is started intitially
and is waiting for the clients, it starts storing all the actions performed in a log called the "Event log"
for the corresponding user session. It requires the user to run the Client login program every time of
a new user wants to connect. The message sent by user hits the server first and the user makes it
display on all the screen of all other users who are online. This is the main focus of our design and is
implemented using the threading. Also, if a user logs off, all other users of the group will be notified
of it and the logged off users loses access over the application. He has to login again to achieve a
connection with the system once again.
SPECIAL ASSUMPTIONS: 1) A user who wishes to login can successfully login with any name,
provided the password is '12345'. The system is designed in such a way for simplicity as this is not
the main focus of our design.
2) Any multiple number of the users can login with the same username, because the system treats
them as different individuals as each and every client is referenced by a unique id.
3) Once a user wishes to log off, he sends a "Goodbye" message and the server disconnects him
from the application and notifies to all other users currently connected.

25. Thesis Statement For The Attorney-Client Privilege
A. Historical Basis
The attorney–client privilege is the oldest of the evidentiary privileges with a history that can be
traced to Roman and canon law. Official references to the rule first appear in English decisions as
early as the late Sixteenth Century. In accordance with the justification for professional privileges in
general, the attorney–client privilege was thought to be essential to the establishment and
preservation of a relationship based on trust between attorney and client. This justification, however,
fell out of favor by the last quarter of the 18th century. The need to ascertain the truth for the ends of
justice was more urgent than the pledge of secrecy. Subsequently, a new justification was found to
sustain this pledge. ... Show more content on Helpwriting.net ...
The first of these characterizes the privilege as a tool of the powerful, a means of allowing the
wealthy to maintain a veil of secrecy around their activities so as to avoid loosening their
stranglehold on power and resources. The second describes the privilege as a way of enhancing the
image of the legal system. According to this view, by safeguarding certain communications between
clients and attorneys, the privilege prevents society from viewing courts as despotic juggernauts,
and prevents the emergence of information after the fact that might undermine the credibility of the
factfinding process.
The last few decades have witnessed extensive debate over the proper scope of the privilege. Much
of this debate is really a debate over the appropriate reasons to have such a privilege at all, since the
differing rationales suggest different formulations of the rule. Courts and commentators do agree
that the privilege should be defined in such a way as to shield no more information than necessary
from the eye of the factfinder. After all, the device "inevitably excludes potentially relevant
information from the consideration of the finder of fact," and thus has the potential to impair the

Securing Client/Server Transactions
The three basic ways that security is implemented in the area of client/server transaction. The first
area is firewalls. The basic idea of a firewall to monitor traffic from a trusted network ( a company's
internal network) to an untrusted network (such as the Internet). Firewalls fall into two categories,
"proxies" and "packet–filtering" firewalls. Packet–filtering determines whether a packet is allowed
or disallowed depending on the source of the packet and the contents of it. Packet–filtering also
looks at the source and destination ports, and to determine if a packet is part of an ongoing
conversation.

Authentication can be performed with a user name and password, or with a piece of information
known as a "digital certificate". A digital certificate contains encryption parameters, which can be
used to uniquely identify a user or a host system. Verifying that an external party has not modified
data is known as "integrity checking". Integrity checking is done by applying a mathematical
algorithm, known as a "hash", to data before it's sent and computing the same hash when the data is
received. If the two hashes map to the same result, then the data hasn't been modified.
How do these areas affect client/server transaction? Client/server transaction deals with the
everyday transactions that people engage in on the Internet. With each transaction, personal
information is sent from client to vendor. The information has a tendency to be sensitive in nature
and not something shared with anyone except the vendor. Such information may include social
security numbers, credit card numbers, and possibly information for monthly bills (account numbers
and balances specifically). Businesses have to save–guard their customers in order for their
customers to feel secure in buying products and services from them. Businesses understand this
importance. Some businesses and development groups have evolved from the need to make business

MEMORANDUM ATTORNEY–CLIENT COMMUNICATION ATTORNEY WORK PRODUCT
TO: Ted Becker FROM: David F. Waserstein DATE: October 16th, 2016 RE: Risk of Exposing
Non–Testifying Consulting Expert ([Party X]) to Discovery or Deposition in [Party Y] Case
INTRODUCTION According to Fed. R. Civ. P. 26(b)(4)(D), a plaintiff cannot discover the facts
known, or opinions held by an expert if: (1) the expert was retained in anticipation of litigation; (2)
defendant does not intend to call a representative of the expert as a trial witness; and (3) plaintiff
cannot prove that exceptional circumstances compel discovery. Protecting trial preparation work of
each party is one of the main justifications for this rule prohibiting discovery and depositions of
non–testifying experts. Courts believe that the disclosure of the identities of a party's non–testifying
experts and consultants represents an unwarranted intrusion into the party's litigation strategy and
provides the opposing party with an unjust advantage. There are also four other commonly
articulated policy considerations underlying protecting the facts or opinions known by consulting
experts from discovery: (1) The "interest in allowing counsel to obtain the expert advice they need
in order properly to evaluate and present their clients' positions without fear that every consultation
with an expert may yield grist for the adversary's mill"; (2) The view that "each side should prepare

Mirror sites are valuable when the original site creates an excessive amount of traffic to support
single server. Mirror sites likewise expand the pace with which files or websites can be gotten to,
clients can download documents all the more rapidly from a server that is topographically closer to
them. For instance, if an occupied New York–based Web webpage sets up a mirror website in
England, clients in Europe can get to the mirror website quicker than the original site in New York.
Sites, for example, Netscape that offer duplicates or upgrades of famous programming regularly set
up mirror sites to handle the expansive request that a solitary site will most likely be unable to
handle. A huge number of people download file in the Server/Client model. The single most issue
for productive exchange is that servers typically have some control over the clients, for example,
limiting the permitted data transfer capacity for one IP addresses. However for a user that needs an

Shared hosting is empowered by separating up the storage room on a web server and assigning areas
to various clients to have their sites. Other than sharing the storage room, clients additionally share
the servers' assets, e.g. its memory and preparing power. The uplifting news, monetarily, is that
running and keeping up expenses are likewise shared, and this is the thing that makes shared hosting
the least expensive type of facilitating you can purchase. It is the most prominent shape and works
superbly well for generally sites. The price range of shared hosting depends from 5 dollars to 20

Thin Client Computer Lab Project
Introduction Computers are an integral part of 21st century life, and as such technology education is
recognized as part of the Illinois Learning Standards (ISBE, 2008). A computer lab is an efficient
way to deliver access to computers and the Internet to students. Traditional labs, like the one at
Dvorak Technology Academy, are populated with complete, standalone computer systems. In
network terms these are "fat clients", because each workstation is a complete system, with its own
memory and disk space and performing most if not ... Show more content on Helpwriting.net ...
A thin client lab will allow Dvorak to extend its financial resources by saving on new computer
resources and extending the life of existing assets. In addition, computer lab fat clients require
substantial maintenance to keep the systems in working order. While CPS's computer support
systems help with this task through programs like Deep Freeze, routine hardware maintenance as
well as software installs and updates not covered by CPS can be a significant drain on technology
coordinator resources. A thin client architecture can reduce the workload of the technology
coordinators by centralizing management and reducing the kinds of workstation maintenance that
needs to be done. Finally, thin client networks are very scaleable. If, in the future, web–based
applications or productivity applications require more processing power than is currently available
in the lab, additional servers can be added to the system to handle the added load instead of
upgrading all of the workstations. As classroom desktop computers are upgraded, the older
classroom machines can be used as additional workstations in the lab, or replace failing lab systems,
or deployed in a new lab.

The BL is running on a separate server, called the business logic tier, middle tier, or service tier.
Finally the DB is running on its own database server. Differences: Client–Server: cost (servers and
software can be expensive) server operating systems (a server and software work together; server
software is expensive; servers also add to the costs) implementation (sharing resources; network
cabling; servers kept in a secure room; central file management, central security administration; user
management and permissions, backup management) security and safety techniques to protect the
network from virus attacks, new products, and the use of new technologies (i.e., wireless
connections).
Client–server networks work best for larger setups, such as a full–scale office or school network ––
especially if the networks are likely to grow in size.
3–Tier Architecture: A 3–Tier usually puts something between the presentation and data store tire
such as a business logic tier.
3–Tier has a Middle part of stage to communicate with client to server, Where as in 2–Tier client

56. Attorney Client Privilege Case Study
In the United States, the doctrine of attorney–client privilege developed as a result of two major
influences: A treatise published by Professor John Wigmore, and the United States Supreme Court.1
Professor Wigmore published his elements of the attorney–client privilege and they are as follows: "
(1) Where legal advice of any kind is sought (2) from a professional legal advisor in his capacity as
such, (3) the communications relating to that purpose, (4) made in confidence, (5) by the client, (6)
are at his instance permanently protected (7) from disclosure by himself or by the legal advisor, (8)
except the protection be waived."2
The United States Supreme Court has also dramatically influenced the doctrine of attorney–client
privilege.3 The court's case law dealing with attorney–client privilege has largely reflected and
expanded upon Professor Wigmore's concepts.4 And from early on in the Supreme Court's history,
the Court recognized the importance of the attorney–client privilege5. For example, in 1876 the
Court described the policy behind the attorney–client privilege as one that allows a person to
"consult his legal advisor without being liable to have the interview made public."6 This policy

Virtualization vs Client Server Architecture
1. Virtualization
The term virtualization is the separation of a resource or request for a service from the underlying
physical delivery of that service.
a. Virtualization Overview
Virtualization allows converting one physical server into multiple virtual machines (VM) where
each of the virtual machines (VM) will operate as a unique physical device. The VMs are capable of
running their own Operating System (OS) and working independently. This allows the administrator
to create enough virtual servers to use all of the physical machines processing power. Figure 1

Virtualization Advantages and Drawbacks
Let us now check the advantages and disadvantages of Virtualization.
a. Advantages
i. Hardware Abstraction: The service vendors create clusters of hardware consisting of storage,
compute resources like CPU and Memory, networks etc., at a preferred location or at different
locations, and then use virtualization techniques to provide access to these clusters. The customer
can ask for the required capacity which can provided immediately. ii. Scalability: Hardware can be
added to the existing setup anytime. Ina client server setup, whenever hardware was added, there
was always downtime associated to it. This is a major benefit that virtualization brings, because if
the requirements is increasing at a rapid rate, then adding the required hardware can actually keep
up without downtime. iii. Consolidation of Workloads: In a client server setup, most physical boxes
are incredibly under–used because of software limitations or usage capacity. But with Virtualization,
resource utilization can be increased by performing load balancing algorithms as the workloads can

These programs detect when keystroke input is being directed to another location besides the
currently targeted window. Most programs will send an alert when such activity is detected
providing a means for early detection and removal before sensitive data is obtained.
For the actual attack that took place there are changes that need to be performed on both the client's
side as well as the server's side. These changes involve limiting the quantities of request either side
can make. For the client's I would recommend a firewall placed between them and the server which
would be configured to limit the amount of requests to be made to any outside source and either
notify and administrator or outright blocking additional requests beyond the threshold.
The same implementation should be made for the server as well. In the server's case the firewall
placed between it and any client should limit the quantity of connection from a source IP. The
unfortunate side of this, and why the client firewall be implemented, is that many clients can be
located behind one source IP address. This means that the server's firewall configuration needs to be
more lenient the the client firewall.
In addition to adding a firewall, the server itself should only allow a certain amount of it's CPU,
memory, and available bandwidth to processing these requests. The reason for this is that the
remaining resource availability allows for an administrator to gain access and

by finding the arithmetic mean. This is the average of the last 5 years. The standard deviation was
then found by using the standard deviation functions in excel. As we can see, these three allocations
have the highest rate of returns of all the available allocations. These allocations also have very high
standard deviations, which make them more risky than any of the other allocations. These are a good
example high risk, high reward. You can from the chart that four years ago these stock options were
very good and then 2 years actually had a negative return. These 3 options would be very good for
someone with a high–risk tolerance and someone who is looking to make a big return and knows
things can go wrong. Both Client 1 and Client 2 will be great candidates for some of these
allocations. The rest of the allocations available to these clients are listed below, along with their

Abstract
Prior to 1994, student registration at Newcastle University involved students being registered in a
single place, where they would present a form which had previously been filled in by the student
and their department. After registration this information was then transferred to a computerised
format. The University decided that the entire registration process was to be computerised for the
Autumn of ... Show more content on Helpwriting.net ...
The high availability requirement implies that the computerised registration system must be able to
tolerate a 'reasonable' number of machine and network related failures, and the consistency
requirement implies that the integrity of stored data (student records) must be maintained in the
presence of concurrent access from users and the types of failures just mentioned. It was expected
that most human errors, such as incorrectly inputting data, would be detected by the system as they
occurred, but some "off–line" data manipulation would be necessary for errors which had not been
foreseen. Tolerance against catastrophic failures (such as complete electrical power failure, or a fire
destroying much of the University infrastructure) although desirable, was not considered within the
remit of the registration system. A solution that would require the University buying and installing
specialist fault–tolerant computing systems, such as Tandem [1] or Stratus [2] was not considered
economically feasible. The only option worth exploring was exploiting the University 's existing
computing resources. Like most other universities, Newcastle has hundreds of networked computers
(Unix workstations, PCs, Macs) scattered throughout the campus. A solution that could make use of
these resources and achieve availability by deploying software–implemented fault–tolerance
techniques certainly looked attractive.

85. Designing A Client Server Application
Abstract–Distributed multiprocessor operating systems is a course that involves exploring new
concepts in the field of operating systems and its internals. This course clearly elaborates the
concepts of operating systems, distributed systems and internals and how are they utilized. It clearly
explains how multiprocessors in operating systems are used in today's world. The course also
involves a four phase project to create a client server application that demonstrates the usage and
application of various concepts like reentrancy, synchronization, etc. operating systems. The project
clearly introduces us to the concepts of distributed memories, remote procedure calls, shared
memory, concurrency, etc. thereby leveraging our knowledge and ... Show more content on

and how can they be applied. As we all know, semaphores can be defined as the variables whose
access are completely dependent on the wait and signal operations that are performed and are also
termed as P and V [1]. It clearly explained the concepts of producer–consumer problems, reader–
writers problems and also helped realizing the potential situations where the problem could actually
arise and also taught the ways in which we could solve these problems. Reentrancy is another key
concept that plays a key role in multiprocessor operating systems. It is under normal cases that
multiple interrupts do occur in a system sometimes. At this point of time, we face certain situations
where some of the functions need to be called back after the interrupt is handled, on the other hand
similarly few of the other functions can be left unhandled [2]. This however depends on the
particular situation that we need during the execution. Hence, calling a function back after the
sudden interruption of its execution is called reentrancy [2]. Similarly, if the function is said to have
an undefined behavior when it is called after an interrupt occurred, then it is said to be non–reentrant
function [2]. This project helped us to implement functions which can be reentrant.
The project has been implemented in four different phases, where each phase acts as an input to the
others.
