Key tools utilized, variable length subnet masking and route summarization are explained as well. Here choosing the appropriate routing protocol is
equally critical for a successful design. To implement different masks for the same major network it is necessary to have a routing protocol that
supports VLSM. Such routing protocols are called classless routing protocols. They carry the mask information along with the route advertisements
therefore allowing for the support of more than one mask. Several classless routing protocol examples include OSPF, RIP version 2, Cisco 's EIGRP,
BGP and IS–IS. We will deploy VLSM for this project. Use of a Class B address 172.17.0.0 is required to support a network that entails a total of 200
sites. The busiest LANs may support up to 100 hosts and there is a maximum projected total of 400 point–to–point WAN links. Hence there is a
requirement for 600 subnets with a maximum of 100 hosts on any subnet. Even with a Class B address there is insufficient address space to meet this
requirement without employing VLSM. When planning a VLSM solution you should start with the shortest mask in other words plan the subnets that
support the most hosts. This is typically the mask that will be used on most or all of the LAN segments. For our network design we propose using
200 LAN segments each supporting up to 100 hosts. While 7 host bits or a /25 subnet mask would meet this requirement, it is probably neater in terms

In time Hoffman became the organization's full time Chief Operations Officer, in other words the senior executive of PayPal in 2000. With this
position his responsibilities increased exponentially to the point where he oversaw managing payment infrastructure, business development, and
following the proper procedures with the legal system. Additionally, he was also responsible for strategy payment innovations, and customer service.
Because of his relentless hard work, Hoffman rose through the ranks and in time became the executive vice president of PayPal in 2002. Then Hoffman
turned his attention towards his original project, which was initially created for the purpose of an online dating site; however, Hoffman made some
revisions in the overall design of his project's architecture. Thus, Hoffman fulfilled his dream of becoming an entrepreneur by revolutionizing the world
of business through the transformation of SocialNet.com. The newly revised structure became known as LinkedIn, which was co–founded by Hoffman
and a few of his former colleagues and friends in 2002. The purpose of LinkedIn was to provide a means of communication between business experts
in order to compare confidential data in the workforce, thus building both trust and respectable reputations for

The Rise Of Personal Computers On The Workplace
The rise of personal computers in the workplace has been very dramatic since their general introduction many years ago. The computing industry is
unique in that it is continuously improving in a never ending effort for enhanced productivity and ultimate portability. From the first personal
computer, the space hogging IBM 610, to the random mix of smartphones, tablets, two–in–ones, laptops, and desktops of today, that mission continues
to refine and polish the idea of the personal computer in an effort to create and re–create the most versatile platform for getting things done. Since the
time of the now incredibly obsolete 610, IBM and many other companies have needed intense research, dramatic reorganizations, extreme designs,
and their subsequent successes and failures to find what will be the "next big thing" in the world of personal computers. As the devices and services
that people use change, so do the jobs of people who manage and service them. An excellent example of this process is in the work of Jon
Bjorkstrand, current Plant Systems and Network Administrator for ConAgra Foods. He is currently responsible for the network operations at two of
ConAgra's Lamb Weston plants, and supports operations at eighteen other ConAgra plants. Bjorkstrand began working for ConAgra at the R. D. Offutt
plant in Park Rapids, MN in 1996, where the current corporate I.T. group had instituted Novell NetWare servers. In his time at the company, he has

A List Of The Best Shopping Cart Software For E Commerce...
There are various types of e–commerce software, hosted, licensed, and Enterprise Resource Planning (ERP). The size of the e–commerce business is

server) is geared toward medium sized ecommerce shops, and hosted (where the software is hosted by the developer), is recommended for very small
or small businesses. I turned to Jasmine A.'s article "A list of the Best Shopping Cart Software for E–Commerce Websites" for details on each
ecommerce software option. Based on Jasmine's article I learned immediately that we could eliminate the hosted solution from the mix as Godiva.com
is not a small shop, and hosted solutions do not integrate well with other software. Additionally, the Godiva site requires customization of the shopping
cart's source code, which is not possible with the hosted option, and lastly, Godiva has more than five product types sold on the site. In considering the
licensed option, although you have control over the software and you are able to customize to a point, Rachel Andrew of Smashing Magazine.com
reminds us that many open–source licensed options force you to use their templates, additionally, they may force you to turn–on JavaScript in order for
the shopping cart to function properly. If you are able to update the script, when the licensed software is upgraded by the system, it may overwrite your

Virtual Network : Virtual Private Network Essay
Today, the technology VPN (Virtual Private Network) has established strong recognition among IT people and every administrator is committed to
organize VPN–channels for employees working outside the office. Virtual Private Network is an association of individual machines, or virtual LAN
network, which ensures the integrity and security of data transmitting. It has the properties of a dedicated private network and allows data transfer
between two computers via an intermediate network such as Internet. VPN has a number of economic advantages over other methods of remote access.
Firstly, users can access the corporate network, without installing with its switched connection, thus eliminating the need to use modems. Secondly,
there is no need for the leased line, which helps to reduce a cost. The main reason that companies use secure VPN, is that they want to send "sensitive"
and / or confidential information over the Internet, without fear that someone will be able to intercept and read the transmitted data. Providers
implementing technology trusted VPN, interested in transferring data at a pre–specified routes through a network of one or more trusted providers.
Differences between trusted and secure VPN stand at the stage of defining requirements to the network. Secure VPN guarantee the confidentiality of
information transmitted, but not responsible for the transmission routes. Trusted VPN provides the necessary routing and delivery time, maintaining

Explain The Purpose Of An Operating System
Explain the purpose of an Operating System: Operating Systems manage hardware and provide services for application software; this means that it
makes it easier for users to interact with different software and hardware available on the computer. The most common operating systems are
Windows, Mac OS X, and Linux. While each OS is different, they all provide a graphical user interface GUI a GUI allows users to click and drag
objects with a mouse instead of entering text at a command line. Characteristics of an Operating System: Multi–User allows multiple users to use the
same computer at the same time or different times. The most common and most well known OS that use s multi–user is Windows 7. Multitasking is
performing more than one task at the same time, a task being a program. Multiprocessing is the support of more than one processor at the same time.
Applications in a multi–processing system are broken into smaller routines that run by themselves. Multithreading is the operating system process to
manage its use by more than one user at a time or manage multiple tasks by the same user without having the need of multiple copies of the program
running on the computer. GUI (Graphical User Interface) allows users to click and drag objects with a mouse instead of entering text at a command

drives, printers, plotters, software, etc. LANs are composed of various components performing specific tasks so each user can access shared
resources. Generally, every component in a network is called a node. Each node is further identified by the specific task it performs. A user's node is
called a terminal or a workstation. This can be a
"dumb" device, meaning it has no operating system, just a monitor and keyboard, or a "smart" node, meaning it can do it's own computing because of
an internal central processor.
A server is a node on the network that provides services to the users of that network. A server will manage hardware and software resources or
monitor the exchange of information through a network. Each server will respond to the requests of a user and provide a service, like printing a
document or retrieving a stored file. There are two basic types of servers: Dedicated and Non–dedicated. A dedicated server performs a specific task or
function all the time where as a non–dedicated server functions in other capacities. A network with servers that are strictly dedicated is called a
Client–Server Network.

A network where services are provided by user's

response to our request for customer support. Red Hat specifically states that it has 24/7 customer support. What that means is that twenty–four hours
and day seven days a week, Red Hat customer support is ready to provide their services. Ubuntu states that it offers profession support to its customers.
Novell also supports the use of Macs and their operation system (OS). Some of the advantages of selecting each vendor's product are similar and still
somewhat distinct. Red Hat in (For sap business,) states, "that is a responsive customer support, higher performance standards, collaborative
engineering for better products, and designed–in security." Customer support is a very important advantage. Higher performance standards are also an
important advantage. Higher performance means we will get what we paid for or more in our return. According to (Stevens, 2011) there are several

Chapter 4 – Describe the impact on users of migrating from a small single server–based network to a directory–based network with multiple servers in
different roles. Also describe the impact on network designers and administrators.
When you have a single server, users will have to login to their local machines via a local account. Any data that they would need access to onthe
network will need to be authenticated via a set of credentials on the server itself. The user in this case will be using two different set of credentials to
access all of their data. When you move into a directory–based network with multiple servers in different roles, things become very easy for both the
users and the administrators. The administrators will need to connect each computer to the domain that way the computer will become trusted and the
user accounts will be able to be authenticated by the domain controller. Both the local computer logins as well as access to all of the data on each and

type of authentication is used between the Windows 2000 Server and the NetWare servers? What network–centric directory structure, if any, is
currently being used?
When you are dealing with both a Windows 2000 server and a NetWare server you can authenticate via Kerberos. This would allow a very easy
transition for the future when the Novell servers are phased out. Another option that can be done is by setting up a radius server that can connect to the

Introduction
Technology has created new revenue streams via the Internet and e–commerce, new connections with clients and consumers at work, home, and by
mobile applications, and enables business to conduct commerce across the US and on a global scale (Munson, 2011). Office technologies have
advanced and have allowed business to advance to a point of doing business with global customers, not just their own areas. It has created a
communication standard that is faster and enables businesses to conduct business at faster levels than ever before. But with new technologies problems
also arise that need to be addressed.
Types of Information Technologies The most prominent example of information technology is the Internet with its World Wide Web component
(Blackhurst, 2002). The Internet has enabled businesses to set up website storefronts that enable consumers all over the globe to shop anywhere on the
web from anywhere they are. A customer in China can shop a website storefront in the US without going to the US to shop the business. Education
Resources Information Center (ERIC) enables search and location of educational literature on a given topic from most of the world. This enables
business to gain employee training materials that promotes the advancement of knowledged employees. Businesses can conduct training sessions at
reduced costs. Other common types of office technologies are the PDAs,

Reliability and Uptime
Network reliability is the ability of a network to maintain or restore an acceptable level of performance during network failures by application various
restoration techniques and prevention of service outages from network failures by applying preventative techniques. (Network Survivability, 2001).
Computing the reliability of a network is quite difficult; therefore estimation by means of simulation is a popular choice for determining network
reliability.
System Response Time
System response time is the interval between the instant a request is entered which requires a response from a remote networked node and the
instant that response is received. Most of the network nodes on the system are Pentium II PC's with Windows 98 operating systems. There is one
Pentium III Windows NT server located at Del Mar and La Jolla. Del Mar and La Jolla employ the use of one print server at each location, while the
Encinitas location does not.
The 56K modem between sites severely impacts the system response time for Kudler's network nodes. Information that is traveling across sites at that
low of a speed means that response times are going to be rather lengthy. The

A small business server handles under 50 users and an enterprise server 50 or more. Novell Netware, Windows NT, and other scalable server solutions
will handle various numbers of small business user loads. At a certain point a business will require an enterprise server product. This OS will be
capable of handling massive user traffic and provide a total solution: a comprehensive set of software tools that will allow a business to be run using
computers. An enterprise OS will be run on a minicomputer such as the HP9000 or a super–microcomputer with large data processing capacity like a
multi–processor Alpha Chip–based machine. Enterprise computing is a term describing a set of software tools with a network OS at its core.
Enterprise computing provides not only a place to store and share files but everything required for a business to gather and manipulate information

Today's enterprise networks are more and more likely to be Windows based or at the very least have large Windows components coexisting with other
network operating systems (NOS) such as the many UNIX/Linux variants, or Novell's NetWare. Since the time that Microsoft began offering Windows
NT Server version 3.51 through today's Windows 2003 Server and its upcoming successor, codenamed "Longhorn", the job of centralized network
authentication and administration has been built around Microsoft's domain network architecture.

The implementation of Microsoft's Active Directory can also assist in actually reducing the number of domains used in a given Microsoft based
network. In the more recent implementations of Microsoft's domain model, all network objects such as computers, printers, users, groups, Microsoft
Exchange mail accounts and other related network components are all stored in Microsoft's Active Directory (DiNicolo, 2004, p. 24–25). Active
Directory can minimize the number of domains required as compared to past Microsoft domain architecture examples by providing a central
repository for network authentication and administration which is capable of replicating its data to other domain controllers within the network using
the process known as multimaster replication (DiNicolo, 2004, p 25). This process allows a domain controller to replicate its Active Directory
database to other domain controllers within the network. This process also enables users at other locations within the network to authenticate and use
the same network resources as other users who are physically closer to the primary domain. In addition, the Dcpromo wizard allows for other Windows
2003 servers within the network to be promoted to the status of

two key business features: information contributions, to be provided by the

Computer Networking, The Transport Layer Of The Internet...
In computer networking, the transport layer is a conceptual division of methods in the layered architecture of protocols in the network stack in the
Internet Protocol Suite and the Open Systems Interconnection (OSI). The protocols of the layer provide host–to–host communication services for
applications. It provides services such as connection–oriented data stream support, reliability, flow control, and multiplexing.
1.1Protocols:
This list shows some protocols that are commonly placed in the transport layers of the Internet protocol suite, the OSI protocol suite, NetWare 's IPX
/SPX, AppleTalk, and Fibre Channel.
ATP, AppleTalk Transaction Protocol
CUDP, Cyclic UDP
DCCP, Datagram Congestion Control Protocol
FCP, Fibre Channel Protocol
IL, IL Protocol
MPTCP, Multipath TCP
RDP, Reliable Datagram Protocol
RUDP, Reliable User Datagram Protocol
SCTP, Stream Control Transmission Protocol
SPX, Sequenced Packet Exchange
SST, Structured Stream Transport
TCP,Transmission Control Protocol
UDP, User Datagram Protocol
UDP–Lite
ВµTP, Micro Transport Protocol
1.2Comparison of OSI transport protocols
ISO/IEC 8073/ITU–T Recommendation X.224, "Information Technology – Open Systems Interconnection – Protocol for providing the
connection–mode transport service", defines five classes of connection–mode transport protocols designated class 0 (TP0) to class 4 (TP4). Class 0
contains no error recovery, and was designed for use on network layers that provide
