CIS 505 Week 3 Discussion 1
IPv6 (Internet Protocol version 6) is a set
of specifications from the Internet Engineering Task Force (IETF) that’s
essentially an upgrade of IP version 4 (IPv4). IP addresses for IPv6 are
128 bits and IPv4 are 32 bits. IPv6 was designed with security in mind
while IPv4 had no security. Both the IPv6 and IPv4 define network layer
protocol and how data is sent from one computer to another computer over
packet-switched networks such as the Internet. IPv6 contains addressing
and control information to route packets for the next generation
Internet. Network address translation (NAT) is eliminated which caused
several networking problems. This age of video/audio, interactive games or
e-commerce needs the capabilities that IPv6 brings. QoS is a set of service
requirements to deliver performance guarantee while transporting traffic over
the network which used in the IPv6.
IPv6 is stronger in security for mobile
devices because each device gets a reliable IP address which permits businesses
to outline a security policy for each device that will apply wherever that
device is used. A higher level of data protection due to encryption being
mandatory. IPv6 built to have encryption from the start to finish.
An issue with IPv6 would be the switching of IP addresses for possible
hackers. This makes it difficult to track and trace criminals

Fat server places more function on the server
while the fat client does the opposite. Fat servers are groupware,
transactions, and the web server. Databases and file servers are examples
of fat clients. Distributed objects can be either. In most scenarios, the
client machines in a fat server based client / server environment are thin
clients. That is, they have very insufficient processing capabilities and
principally rely on the fat server. Transaction and object servers encapsulate
the database. Fat servers try to minimize network interchanges by
creating more abstract levels of service. These applications are easier
to manage and deploy on the network because most of the code runs on servers.
Fat clients are used for decision support and
personal software. The more traditional form of client/server is fat
clients. Versatility and possibilities for generating front-end tools
that let end-users create their own applications. Fat clients can work
independently; the functioning is smooth as there is no load on the server.
Software licensing costs are decreasing as a result of which thick clients seem
to be becoming more popular.
An intranet is a private computer network
that operates within an organization and facilitates internal communication and
information sharing with the same technology used by the internet. The
major difference is that an intranet is confined to an organization, while the
Internet is a public network that operates between organizations.
The Internet serves businesses by creating
opportunities for networking, information retrieval, communications, marketing,
and sales. The internet is used by companies as a tool to sell products
to consumers all around the globe. Companies such as eBay or Amazon are
online stores that sell various of products. Companies can also use the
Internet for internal communications and other electronic activities, which
many small businesses do in lieu of developing their own networks.
Pros of an Intranet are increased employee
productivity, allows for greater collaboration, provides a social networking
platform, simplifies decision making, streamlined data management. Cons
are one’s company could be at risk without a strong security foundation,
time-consuming and expensive, and can be counterproductive.
The Internet is an accessible, unrestricted
space, while an intranet is created to be a secret space. An intranet may be
obtainable from the Internet, but as a precept, it’s guarded by a password and
open only to employees or other approved users. If we execute a single
interspersed system, we only need one developer organization. From within a
business, an intranet server may react much more swiftly than a regular Web
site. This is because the unrestricted Internet is at the tolerance of passage
spikes, server failures and other obstacles that may impede the network. Within
an organization, however, users have much more bandwidth and network hardware may
be more stable. This makes it simpler to serve high-bandwidth content, such as
audio and video, over an intranet.
