...TCP/IP LAN Plan CheckPoint An IPv6 address is 128 bits compared to the IPv4, which is only 32 bits. The subnet mask of an IP address, defines the network portions and which part is the host portion. Each of the three class IP addresses have a range, which cannot be routed across the internet. Since the IP address 172.19.243.254 falls in the range of the class B 172.16 to 172.31 ranges it cannot be routed across the internet. Computers to communicate on a TCP/IP logical network they must have an IP address. An IP address is unique to the devices on a network providing the network ID and the host ID there for, for a computer to talk to another computer within a logical network they both must have an network ID and a host ID. Reallocating bits from the host ID to a network ID one must remember subnets take the power of 2, meaning to create 16 subnets one must reallocate 4 bits to the 2 power (2x2=4x2=8x2=16). A class C network address is 255.255.255.0, leaving the last octet for identification of subnets. 32 subnets equals 6 bits, converted to binary provides a 11111100 binary bit pattern with the sixth 1 representing the 32nds place. The binary bit pattern 11111100 is equal to (128+64+32+16+8+4) 252, which is a subnet mask of 255.255.255.252. To assign address to 62 hosts one must use the formula 2n-2 with n representing the number of host bits. 62 host is (2*2=4*2=8*2=16*2=32*2=64-2=62) 6 host bits. Why subnet, the ability to break up large networks in...

...layers over multiple physical tiers. This can make a very good impact on your application by Improving performance (sometimes), scalability and fault tolerance. The maintenance of your application is easier because of the low coupling between layers. Adding more functionality to your application is made easier. Layers make your application more testable. Building a well formed layers makes the orientation in your application easier. Having your application not layered means that you have to deal with all security threats in one place which is very difficult. Having your application distributed to layers makes it much easier for design and implement Without a good deployment plan it is not trivial to distribute your layers over multiple physical tiers in distributed computing. You need to plan ahead your layers when you create a distributed application. 3. What is a protocol and why would one be used?

...Darrel Smith IT255 11/29/2011 Research Assignment 2 A sound security plan is the first step towards a multi-layer defense. To develop a plan, the company must access its most important assets; identify vulnerabilities as well as the infrastructure and technology most appropriate for mitigating risk, then implement a strategy for putting the plan in action. Emails are prime examples. It has become a critical business communications tool and is also a primary conduit for malicious code. Protecting emails against viruses, worms, spam, Trojan horses, phishing attacks and other threats requires a variety of security technologies. These antivirus and antispyware software, content filtering, and firewalls. Such security technologies must be installed at various levels of the infrastructure-such as the gateway, mail servers and desktop or laptop. This way, threats that may bypass one level are dealt with at another. In addition, layering security helps mitigate the risk of an employee who disables protection on his or her desktop. The gateway serves as an entry and exit point to the company network. By installing a security solution such as antivirus and content filtering at this tier, mass-mailer worms are scanned and deleted and spam is moved to quarantines. Mail servers should also be equipped with security. These systems receive, send, and store email, and an email security solution work together with the email program to provide a greater degree of protection against...

...Individual Final Project NTC/362 Fundamentals of Networking Dean McIntyre 2 The Patton-Fuller Community Hospital looks to upgrade their Information Technology (IT) capability beginning with their networks. The characteristics, components, and topology are evaluated to properly identify the needs for the new network design. The plan includes converting to a Wireless Local Area Network otherwise known as (WLAN), installing a Voice over Internet Protocol otherwise known as (VoIP), and design a Wide Area Network (WAN). The plan also includes the hospital maintaining all Macintosh® computers. Administration/Clinical Overview * The administrative departments run off of a 1000 Base-T Ethernet provided by a CAT 6 cable which is also the entire hospital’s network backbone. Clinical department networks however are provided by a 1000 Base-F Ethernet provided by a single mode fiber. The clinics feed into a Cisco Catalyste 3560 Switch as the network bridge that links the two together. All workstations are Apple iMAC or MAC Pros with the executive management, senior managers, and the data center workstations as having a wireless communication card installed. * IT Data Center * The data center is comprised of the hospital HIS system. The mainframe of the HIS is connected by a 4 gigabit fiber link to a 10 terabyte Network Area Storage (NAS) device. The data center’s workstations are all Apple iMACs that run a MAC OS X from a remote desktop. Virtualization...

...Terminology Video Conferencing Standards and Terminology. There is an ever increasing number of standards, terminologies and buzz-words used within the video conferencing industry that can make understanding what is both available and compatible a minefield. We have the H.300's, the G.700's, the T.120's and the H.460's, not to mention ISDN, LAN, WAN, ADSL, VPN and POTS all mixed with NTSC, PAL and CIF. To complicate matters more, we also have to deal with the forthcoming media-enabled 3G mobile phone and how this links in with existing systems. This document explains what these standards, terminologies and buzz-words mean, how they relate to the various communications infrastructures of video conferencing and how they relate to each other. It is assumed that the reader has a general knowledge of Video Conferencing systems. However, the following technical papers are available to provide more information: * How do I choose a Video Conferencing system? * H.323 Terminals, Gatekeepers, Gateways & MCUs. * Global Dialling Scheme (GDS) for Schools VideoConferencing. * H.323 Dial Plan and Service Codes used by Gatekeepers etc. * IP Ports and Protocols used by H.323 Devices. * Cost Efficient ISDN Conferencing, including Multipoint Access. * H.221 Framing used in ISDN Conferences.

...on the ARPANET to over 300,000 computers on many interconnected networks. As ARPANET grew to include more computers, researchers realized the need for each connected computer to conform the same set of rules. The Network Control Protocol (NCP) was developed as the first collection of rules for formatting, ordering, and error-checking data sent across a network. Vincent Cerf, who is often referred to as the Father of the Internet, along with his colleague Robert Kahn, developed the Transmission Control Protocol and the Internet Protocol (referred to by their combined acronym TCP/IP), which are still used today. The Transmission Control Protocol (TCP) includes rules that computers on a network use to establish and break connections. The Internet Protocol (IP) includes rules for routing individual data packets. The term Internet was first used in 1974 in an article written by Cerf and Kahn about the TCP protocol. The open architecture philosophy ensured that each...
