...Network Basics Server- system that responds to requests across a computer network to provide a network service. AW server is the server, the software and the data they generate. Client- computer that receives services from a server. AW server install a client in PCs that accesses the AW server Node- any addressable location on a network; can be a phone, printer, monitor, a CT, AW server. How many nodes are you going to connect? Meaning how many connections are you going to have to the network- as in if the doctor, a nurse and tech want it they are already connected into the network. We connect one and that is the server for AW. Mixed mode networks, meaning different nodes connected. Main line of connection in the network is the backbone. NIC (network interface card) card, card needed for networking without it you can’t connect to the network; give a MAC address specific address for that node. It is physically configured on the node. Some customers will not give you the info you need until they get the MAC address- how do you get it? You have the FE do it at install. Servers have multiple NIC cards, “redundancy” Hand FE the IP info the FE before install. Software- must be configured Protocol- how do I communicate with you (IT uses this a lot). Need to know to talk to each other you need an IP address (internet protocol address) subnet mask, and default gateway. IP- connect to the network on a unique address Subnet mask- lets you group like computers together...

The Ethernet and PPP in data transfer. There are different methods for the effective transfer of data between different nodes. Ethernet and Point-to-point protocol are two of them. Ether net can be defined as a family of computer networking technology used for local area networks (LAN). The functioning of Ethernet is based on a set of coding system which allows the coding violations to mark the frame boundaries. It also defines the network layer interfaces to the physical interconnects. There are several important features and advantages for the Ethernet; but there are some disadvantages too. One of the disadvantages is - it will not operate on wide variety of media, which includes the async serial ports which are usually used with the dial up modems and synchronous telecom services. Using Ethernet, only on synchronous links, it will be able to use 100BASE-TX 4B/5B or 1000BASE- X 8B/10B encoding for making an Ethernet-like serial implication. And the result of this will be less efficient too. Point-to point protocol is a commonly used data link protocol for establishing direct connection...

...PROBABILITY (module 4 & 5) Probability for a discrete variable Probability for a discrete variable=chance of the discrete variable taking on a particular value, expressed as a percentage These can be estimated by experiments or observations, called empirical probability. Explained in excel Probability Distribution: A Tabulated view of the uncertain behavior of a discrete random variable Cumulative Distribution: Another Tabulated view of the uncertain behavior of a discrete random variable Expectation of a variable: A weighted average taking into account the probability. Difference between DV and Random Variable. ***We control a decision variable, and so we can stop being uncertain about it any time we want to make the decision. Random variables are used in decision-analysis models only to represent quantities that we do not know and cannot control.

...issue with wireless laptops connected to the corporate network, it presents a situation where a hacker could sit in the parking lot and receive information through laptops and other devices, or break in using the wireless card-equipped with this wireless connectivity option. In order to test the strength of most wired and wireless networks the intrusion detection system was implemented. This is a software application that monitors the network activity for malicious activity or privacy violations. The way this works, is that the incidents get reported to a management station. The two different types of intrusion detection system are (NIDS) network based and (HIDS) Host based intrusion detection systems. The next step in security would be to assign a (IDPS) Intrusion detection and prevention system. When applied this tracks and monitors the system being used for hazardous or malicious activity. The purpose is to log and keep track of any activity that may seem like a malicious act in any way. There are plenty of ways to ensure that you have your wireless...

...CHAPTER I Project Title Proposed Computer Virtualization of NEUST-Gabaldon Computer Laboratory Using Thin-Client Network Project Description NEUST-Gabaldon Campus (Formerly Sabani Estate Agricultural College) established their computer laboratory on 2011 which help the students of College and High School for their computer subjects (Office Productivity). Since then, the computer laboratory has its computer administrator in presence of Mr. Jefrain M. Padre, although there was computer network architecture in the campus there were times that the computer had some troubles including the System Unit and its operating system. So, the researchers decided to make a proposal entitled “Proposed Computer Virtualization of NEUST-Gabaldon Computer Laboratory Using Thin-Client Network”. The proposed project used virtualization for it was essentially lets one computer do the job of multiple computers, by sharing the resources of a single computer across multiple environments. Using an Ncomputing M300 (thin-client) series connection of network it was possible for the entire project. Thoroughly, the entire project covered up network of computer using this device (Ncomputing M300 series) to connect through a server in a series type of network. Also, using a server with a high specification it will then try to run at least one programming language that can be used by the Bachelor of Science in Information Technology students of Gabaldon Campus.

...Answers to Review Questions 1. Name and discuss the different levels of data abstraction as defined by ANSI/SPARC. Conceptual Located at the abstraction apex, the conceptual model represents a global view of the data. It forms the basis of the conceptual schema, which provides a relatively easily understood bird's-eye view of the data environment. Since the conceptual model focuses on the main data objects and avoids detail, it exhibits both software and hardware independence. The most widely used conceptual model is the Entity Relationship (E-R) model, which yields the basic database blueprint. Internal The internal model represents the adaptation of the conceptual model to a specific DBMS. Basically, the internal model requires the database designer to match the conceptual model's characteristics and constraints to those of the selected hierarchical, network, or relational DBMS. Therefore, although it is still hardware-independent, it is software-dependent. External The external model represents the applications programmer's view of the data environment. Its use requires that the modeler subdivide a universal set of requirements and constraints into functional modules, each represented by its own external model. (The modules correspond to business units such as production, sales, personnel, and so on.) Each external model is represented by its own external schema. Each business unit is thus represented by an external model that includes that unit's entities...

...Ch08.qxd 10/28/04 2:54 PM Page 181 Psychological measurements: their uses and misuses 8 ‘Measure all that can be measured and render measurable all that defies measurement.’ Galileo Galilei ‘Not everything that counts can be counted, and not everything that can be counted counts.’ Albert Einstein The words ‘test’ and ‘measurement’, as used in psychology, are misleading because of the implied similarity to scientific measurements and medical tests. Conventional psychological testing is quite different from scientific measurements in natural sciences. What is accomplished by the application of psychological measurement is an estimation of a psychological construct. Psychological tests and measurements of personality, intelligence, attitude and motivation are fundamentally different from quantitative measurements in physical sciences such as height, weight and blood urea. Paul Kline, one of the foremost exponents of psychometric theory clarifies the issue as follows: ‘There are no units of [psychological] measurement and no true zeros. Whatever psychological measurement is, it is not scientific measurement as defined in natural sciences ... If we consider what is meant by intelligence or extraversion, just for example, it is by no means clear what units of measurement might be used or what the true zero may mean. This problem applies to the majority of psychological concepts and variables’ (Kline, 2000). Besides, it is often mistakenly believed...
