...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...

...An Analysis of Linux Scalability to Many Cores Silas Boyd-Wickizer, Austin T. Clements, Yandong Mao, Aleksey Pesterev, M. Frans Kaashoek, Robert Morris, and Nickolai Zeldovich MIT CSAIL A BSTRACT This paper analyzes the scalability of seven system applications (Exim, memcached, Apache, PostgreSQL, gmake, Psearchy, and MapReduce) running on Linux on a 48core computer. Except for gmake, all applications trigger scalability bottlenecks inside a recent Linux kernel. Using mostly standard parallel programming techniques— this paper introduces one new technique, sloppy counters—these bottlenecks can be removed from the kernel or avoided by changing the applications slightly. Modifying the kernel required in total 3002 lines of code changes. A speculative conclusion from this analysis is that there is no scalability reason to give up on traditional operating system organizations just yet. but the other applications scale poorly, performing much less work per core with 48 cores than with one core. We attempt to understand and fix the scalability problems, by modifying either the applications or the Linux kernel. We then iterate, since fixing one scalability problem usually exposes further ones. The end result for each application is either good scalability on 48 cores, or attribution of non-scalability to a hard-to-fix problem with the application, the Linux kernel, or the underlying hardware. The analysis of whether the kernel design is compatible with scaling rests on the extent to which...

...DESIGN AND ANALYSIS OF A CHASSIS FOR A 60 TON PAY LOAD Abstract: As the chassis frame forms the backbone of a heavy vehicle, its principal function is to safely carry the maximum load for all designed operating conditions. To achieve a satisfactory performance, the construction of a chassis is the result of careful design and rigorous testing. Various manufacturers have individual design concepts and different methods of achieving the desired performance standards for the complete chassis, not all chassis components are interchangeable between various makes and models of vehicles. So, there is no standard design for chassis frame. Even though start with the chassis frame design start with selection of the section for side rails and cross members. In this paper we have designed a chassis for storage cum resting fixture. Storage cum resting fixture is a structure of length 11000mm & width 2300mm, used to store cylindrical specimens of various sizes and weights in horizontal configuration. The storage cum resting fixture is used to carry the propellant stored in the cylindrical specimens. The trolley fixture should be designed for a maximum pay load of 60 tons. The Objective of my project is to design a chassis for a pay load of 60 Tons. The design process involves manual design calculations, 3d modeling using UNIGRAPHICS software and analysis to validate the design. Ansys package has been implemented to perform the structural analysis. ...

...Journal of Economic Geography Advance Access published June 22, 2005 Journal of Economic Geography (2005) Page 1 of 30 doi:10.1093/jeg/lbi001 Video games production networks: value capture, power relations and embeddedness Jennifer Johns* Abstract This paper has two main aims. Firstly to conceptualize the production networks of the video games industry through an examination of its evolution into a multi-million dollar industry. Secondly, to use the video games industry to demonstrate the utility of Global Production Network approaches to understanding the geographically uneven impacts of globalization processes. In particular, three key notions of value, power and embeddedness are used to reveal the most powerful actors in the production network, how they maintain and exercise their power, and how the organization of production is manipulated as a result. It is argued that while hardware production is organized by console manufacturers using truly global sourcing strategies, the production of software is far more complex. In fact, software production networks are bounded within three major economic regions: Western Europe, North America and Asia Pacific. This paper seeks to explain how and why this has occurred.

Concordia is mid-sized bank based out of California that has a wide area network consisting of 125 branch offices spread out through California and the surrounding states. Concordia has implemented a project to get out of the information technology area so that they can focus on their core principles of the banking industry. Concordia preferred to leave the technical part of their infrastructure to the experts. The executives decided that outsourcing their infrastructure to a managed service provider, who specializes in wide area network management, will help the company reduce costs and help keep their environment current on technology trends. The outsourcing of Concordia’s infrastructure can cover many aspects, including servers,...

...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.

...NT 1210 M1 Case studies # 9 Dear Mr. Sheehan: I would like to thank you for agreement regarding my recommendations to the company about deploying a SAN at each branch office, since each office uses data, audio, video and graphic files that are shared by staff at each location. The SAN may incorporate NAS devices which we have evaluated with different vendors. As we conducted a further research in order to provide you with more detail specifications on SAN and NAS solutions, we were able to come up with the following information design in a form of questions and answers. What is required to implement a SAN and /or NAS? Storage-area networks (SANs) are composed of computers and remote storage devices. The computers are typically connected to the remote storage devices using SCSI over Fibre Channel (see Figure 1). Other implementations of SAN exist, but this is the most common. In a SAN, all the storage appears local, just as if the remote disk were directly connected to the computer and physically located inside the computer chassis. Network-attached storage (NAS) devices appear to the user as a remote drive letter or are named remote storage device. Typically, the operating system employs a protocol such as Network File System (NFS) or Common Internet File System (CIFS) to discover, log in, and transfer content to and from a storage device. NFS and CIFS both communicate over Ethernet. The user typically enters a username and password, and then is granted access to a particular...
