Domain 1.0: Network Technologies
Domain 1.1: Common Networking Protocols
TCP - TCP breaks data into manageable packets and tracks information such as source and destination of packets. It is able to reroute packets and is responsible for guaranteed delivery of the data. IP - This is a connectionless protocol, which means that a session is not created before sending data. IP is responsible for addressing and routing of packets between computers. It does not guarantee delivery and does not give acknowledgement of packets that are lost or sent out of order as this is the responsibility of higher layer protocols such as TCP. UDP - A connectionless, datagram service that provides an unreliable, best-effort delivery. ICMP - Internet Control Message Protocol enables systems on a TCP/IP network to share status and error information such as with the use of PING and TRACERT utilities. SMTP - Used to reliably send and receive mail over the Internet. FTP - File transfer protocol is used for transferring files between remote systems. Must resolve host name to IP address to establish communication. It is connection oriented (i.e.…...

...publisher (CANdiensten, Nieuwpoortkade 25, 1055 RX Amsterdam, The Netherlands). ISBN 90-804652-2-4 Preface In September 1997 Insightful (formerly known as MathSoft) released S-PLUS 4 for Windows, which added a complete new graphical user interface to the existing S-PLUS programming environment. It allowed non-programming minded users to access the advanced visualization techniques and modern analysis methods of S-PLUS. As a result, S-PLUS has gained enormous popularity over the past years among applied statisticians and data analysts. Over the last three years the content of this book has been used for introductory courses on S-PLUS. This book is aimed at people who are (completely) new to S-PLUS. It covers the graphical user interface of S-PLUS and introduces the underlying S language. The main goal of this book is to get you started and the best way to do that is to use this book interactively during an S-PLUS session. After reading this book you should be able to import data into the system, do some data manipulation and data cleaning. Furthermore, you should be able to visualize your data, apply statistical functions to your data, enter basic S-PLUS commands and write functions. The first edition of this book appeared in 1999, it was aimed at users of S-PLUS 2000. This edition is updated for S-PLUS 6 (see Appendix C for a list of new features). Chapters 8 and 9 about the S language have been restructured and extended. Throughout the book more examples are given,......

Member, Organization, Employee MOE is a decision making filter used by A.P. in handling members’ loans when they get into financial trouble. This new approach has moved the strategy of the Credit Union from collecting payments (until 2002, performance was measured according to financials) to building relationships based on trust with the members. The stakeholders team at Affinity Plus has pushed the concept of members-first deeply throughout the organization, empowering employees to put member-owners’ interests ahead of either the organization’s interests or their own interests: what is best for customer is best for all. The system is very effective in delivering value to customers. CU is embarking on creating solutions for its members who are delinquent and financially troubled, instead of focusing on collecting payments by calling early or even sometimes aggressively. From the standpoint of CU, those members are solely in ill-health financially at the time of borrowing and their situation will recuperate in due course once they find a solution to help its member. At the end, customer will benefit from settling his delinquency by the help of his trusted CU. 2. In your view, is MOE likely to be effective in creating value for Affinity Plus?

...TYPES OF COMPUTER NETWORKS Maninder Kaur professormaninder@gmail.com What is Network? • A network consists of two or more computers that are linked in order to share resources (such as printers and CDs), exchange files, or allow electronic communications. • The computers on a network may be linked through cables, telephone lines, radio waves, satellites, or infrared light beams. Different Types of Networks • Depending upon the geographical area covered by a network, it is classified as: – Local Area Network (LAN) – Metropolitan Area Network (MAN) – Wide Area Network (WAN) – Personal Area Network (PAN) Local Area Network (LAN) • A LAN is a network that is used for communicating among computer devices, usually within an office building or home. • LAN’s enable the sharing of resources such as files or hardware devices that may be needed by multiple users • • Is limited in size, typically spanning a few hundred meters, and no more than a mile • Is fast, with speeds from 10 Mbps to 10 Gbps • Requires little wiring, typically a single cable connecting to each device • Has lower cost compared to MAN’s or WAN’s Local Area Network (LAN) • LAN’s can be either wired or wireless. Twisted pair, coax or fibre optic cable can be used in wired LAN’s. • Every LAN uses a protocol – a set of rules that governs how packets are configured and transmitted. • Nodes in a LAN are linked together with a certain topology. These topologies include: – Bus – Ring –......

Network

...Network Attached Device Network-attached storage (NAS) is a dedicated hard disk storage device that is set up with its own network address and provides file-based data storage services to other devices on the network. It is attached to a local area network and assigned an IP address, allowing both application programming and files to be served faster because they are not competing for processor resources. NAS devices are usually configured with a web browser and do not have a keyboard or display. Consists of hard disk storage, including multi-disk RAID systems and can usually handle a number of network protocols, including Microsoft's Internetwork Packet Exchange and NetBEUI, Novell's Netware Internetwork Packet Exchange, and Sun Microsystems' Network File System. (Rouse, 2013) NAS devices speed is typically one gigabit Ethernet connection but this can be changed to multiple gigabit, 10 gigabit, fiber optic by adding a pci-e network card(s). Older parts can be used which may be limited to 10/100 megabit. If you need an exact answer for speed, simply look at the wiki on gigabit. The capacity range varies, people have built 40 TB (terabyte) machines and other just have 2TB. With port replication and add on hard drive controller cards there is hardly a limit on size. A board with 6 SATA ports can be replicated (1 to 5 port) allowing for 30 drives to be attached, if 3TB drives were used in raid 50 that would be 72TB of storage. As far as fault tolerance, raid 50...

Wireless Networks & Network Security

...Wireless Networks & Network Security ISSC 340 Professor Vijay Venkatesh James Lange 08/13/2013 Wireless Networks are somewhat new technology in comparison to the know-how that makes them possible. The knowledge regarding wireless technology goes back about 200 years. One of the first individuals deserving recognition for today’s wireless networks is a scientist, inventor and politician named Benjamin Franklin. In 1747 he had built a model that showed how electricity could move through the air unaided by any type of wiring. In the early 1750’s Mr. Franklin started experimenting with electricity and the rest is history. Franklin was under the belief that lightening was an electrical current. So with the famous kite and key experiment he proved to himself and others that he was right. His fascination with electricity led him to later experiments with an electrical tube given to him by a friend. A second individual that played a part in today’s wireless technology is Hans Christian Oersted. In 1819 he had found that a compass needle had movement if it was presented with electrical current. This relationship between the needle and the electricity is an essential part of electromagnetism. It is said that this discovery by Oersted happened completely by chance. While preparing for one of his lectures he was setting up some of his equipment. The compass and battery were in close proximity to each other and the needle moved from magnetic north whenever the switch to......

...INTRODUCTION The term MANET (Mobile Adhoc Network)refers to a multihop packet based wireless network composed of a set of mobile nodes that can communicate and move at the same time , without using any kind of fixed wired infrastructure. MNET are actually self organizing and adaptive networks that can be formed and deformed on-the-fly without the need of any centralized administration. As for other packet data networks, one –to-one communication in a MANET is achieved by unicast routing each single packet. Routing in MANET is challenging due to the constraints existing on the transmission bandwidth battery power and CPU time and the requirement to cope with the frequent topological changes resulting from the mobility of the nodes. Nodes of a MANET cooperate in the task of routing packets to destination nodes since each node of the network is able to communicate only with those nodes located within its transmission radius R, while the source and destination nodes can be located at a distance much higher than R. A first attempt to cope with the mobility is to use the specific techniques aimed to tailoring the conventional routing protocols to the mobile environment while preserving their nature. For this reason the protocol designed around such techniques are referred to as table-driven or proactive protocols. To guarantee that routing tables are up to date and reflect the actual network topology, nodes running a protocol......
