UNIT 6 RESEARCH PAPER 1: NETWORK ATTACHED STORAGE NT 1110 WAYNE HOVIS PART 1

What is a NAS device?

A network-attached storage (NAS) device is a server that is dedicated to nothing more than file sharing. NAS does not provide any of the activities that a server in a server-centric system typically provides, such as email, authentication or file management. NAS allows more hard disk storage space to be added to a network that already utilizes servers without shutting them down for maintenance and upgrades. With a NAS device, storage is not an integral part of the server. Instead, in this storage-centric design, the server still handles all of the processing of data but a NAS device delivers the data to the user. A NAS device does not need to be located within the server but can exist anywhere in a LAN and can be made up of multiple networked NAS devices.

What is the speed of the network adapter available on a NAS device?

The speed is usually 1GB Ethernet connection but it can be changed to multiple Gb, 10Gb, fiber optic by adding a PCIe network card(s). It depends on the NAS device. Most newer ones will have Gigabit ethernet, very cheap or old ones may only be 100Mbit and high end ones may have 2 separate gigabit ethernet connections.

What is the capacity range?

Depending on the type and volume of content you plan to store, there's a choice of capacities available all the way up to huge multiple TB (Terabyte) versions. A 160GB capacity for example would be enough storage for around 40,000 average audio tracks or up to 200 hours of video content. If you'll be using your NAS device to store masses of content, including High Definition content, or indeed backing up multiple user's PCs, you'll need a bigger capacity.

...1970’s Dartmouth Basic- was created by John Kemeny and Thomas Kurtz on May 1, 1964. Basic stands for Beginners All-purpose Symbolic Instruction Code . The aims of the BASIC system were: to develop a system and language that was friendly, easy to learn and use, to introduce computing as an adjunct to other courses, to operate an open access policy (i-programmer.info, 2010). Pascal- was created by Niklaus Wirth in 1972. He wanted a language suitable for teaching but for teaching computer science. It is best described as a simplified version of Algol. It was simplified both to make it easier to learn and to make it easier to compile (i-programmer.info, 2010). C- Was created by Ken Thompson iin the form of B and tweaked by Dennis Ritchie and renamed C in the 1970’s. It was the original code Unix was written in. Its function was for ease of use (i-programmer.info, 2010). Forth- was created by Charles H Moore in the 1970’s. The motivation behind this language was for both interactive execution of commands and the ability to compile sequences of commands for later execution (i-programmer.info, 2010). PLEX (Programming Language for EXchanges)- was created by Goran Hemdahl at Ericsson in the 1970’s.

Unit 2 Research Paper 1

...Cindy Vargas GS 1140 Unit 2 Research Paper 1 The issue that I want to bring to the table is that our prisons in the United States are filling quickly with repeat offenders. If there was a way to rehabilitate the prisoners why not take it? It would appear from the research that I’ve done that our prison system is geared more towards punishment than rehabilitation. Throughout this paper I will discuss the program I think we need to help reduce the overcrowding of prisons and the return of previous criminals. The Department of Justice data shows that around 730 in every 100, 000 people are incarcerated in the U.S. We currently have 2.2 million people behind bars equal to the size of Houston, Tx. (Natasha Lennard, 2012). My proposition is to adopt the Israeli rehabilitation program into our justice system. Israel is a small country of a population at about 8 million people. This small country has 32 prisons and only estimated 18, 000 people incarcerated. Their recidivism of repeat offender rates are amongst the lowest in the word (Matt Lebovic, 2012). At Hermon prison in Galilee still has the same security measures that you expect from a prison. The way that they treat the inmates and the way the inmates interact with each other is what makes this program so special. The inmates aren’t called inmates they are called “residents”, they walk around the prison as if were a college campus. The unrestricted access to each other is what helps them integrate back into society.......

Network Topology Paper Assignment 1 Unit 3

...Network Topology Paper Assignment 1 Unit 3 Mr. Swailes The study of Network Topology recognizes 8 basic topologies * Point to point * Star * Bus * Mesh * Tree * Hybrid * Daisy chain * Ring Point to point- The simplest topology is the permanent link between two end points Star-in a local area network with a star topology. Each network host is connected to a central hub with a point-to-point connection to a central node called a hub or switch. Bus- In local area networks where Bus Topology is used, each computer is connected to a single Bus cable. A signal from the source travels in both directions to all machines connected on the Bus cable until it finds the intended recipient. If the machine address does not match the intended address for the data, the machine ignores it. However, if the data matches it is accepted. The bad part of this topology is that it has a single point of failure which is the cable and if this happens the whole network can shut down. Mesh-is a fully connected network in which each node is connected to each other. A fully connected network does not need to use switching or broadcasting. However its major disadvantage is that the number of connections grows with the number of nodes. It is extremely impractical for large networks. A two node network is technically a fully connected network. Tree-is a combination of a Bus and Star topology. It is arranged to look like a tree. The advantages are it is......

Nt-1110 Unit 6 Research Paper

...Matt Bristow NT-1110 Unit 6 Research Paper NAS Devices NAS is an acronym for Network-Attached Storage. It is basically a file-level computer built for data storage connected to a computer network providing data access to any computer connected to that network. The speed for any particular NAS device varies from 1 gigabit all the way up to 10 gigabits depending on what upgrades a pc has such as an upgraded network cards. The capacity range for NAS devices also depend solely on the budget set forth. It can be a low range system with 500 gigabytes, all the way up to a wallet-busting 16 terabytes. The fault tolerances when set at RAID 10 are the most stable since more devices can fail while protecting against any potential data loss. The advantages of an NAS device are that since it is a dedicated file storage device, accessing said data is a lot faster than typical in-pc hard drives. Another advantage would be the amount of storage you're capable of having. It far outpaces pc's in storage capabilities because all it is built for is storage. For a family with a lot of pictures or videos, the advantages are that any computer connected to the NAS device can access them. It's a library for any media/documents/or anything else you can think of that can be accessed at any time by any pc connected to it. They might be pricey for a casual pc user but when dealing with multiple pc's connected to a single network, an NAS device would be the perfect option when space becomes an issue...

Unit 6 Research Paper 1 Network Attached Storage

...NT1110 July 31, 2013 Unit 6 Research Paper 1: Network Attached Storage A network-attached storage (NAS) device is a self-contained computer that is connected to a network. A NAS contains its own operating system that handles the function of data storage, file system, and the access to the files but doesn’t include a monitor, keyboard or other devices. NAS is dedicated for file sharing and allows more hard disk storage space and doesn’t need upgrades. The available speed of a NAS device varies but the usual speeds are 1 GB Ethernet connection however it can be changed to a multiple of GB and fiber optic by adding a PCIe network card(s). The capacity range also varies because there is no real limit to the NAS for example a board with six SATA ports can be replicated to allow thirty drives to be attached and up to 72TB of storage. There is fault tolerance (RAID) built into a NAS device if set up correctly RAID 50 is fairly stable, RAID 10 has been advertised as one of the best set ups because more drives can fail at one time without having data loss. A NAS device over all has its advantages it is great for file sharing and keeping all your files safe. So in a house where children and parents all have their own computer with pictures and videos it benefits them to have a NAS device where they can just store all those files and not worry about if one computer goes down all the files go along with the computer. http://technicallyeasy.net/2008/06/what-is-nas-device/......

Unit 6 Research Paper Network Attached Storage

...Jonathan Bowden October 27, 2014 NT1114 Unit 6 Research Paper Network Attached Storage A Network Attached Storage device is like having an at-home cloud. It allows all the computers in a household to access the same massive storage device. Since NAS devices start at 2 TB of data, they can hold everything your family is going to need. If a single computer gets damaged and you are using a NAS device, you don’t have to worry about all of your data being lost. The computer is broken, but all of your home videos and pictures are safe and sound on your NAS device. There really are no limits to Network Attached Storage. With 1 GB Ethernet you can transmit just about everything you want as fast as you’re going to need it. You could also use a 10GB fiber optic cable too if you really wanted to. I guess the only real limit would be on a wireless network where you would be limited to the speed of your wi-fi connection. The capacity range of a NAS device is really only limited to the size of hard drives. A board with six SATA ports can be replicated to allow for 30 drives to be attached, if 3 TB drives are used in RAID 50 that would be 72 TB of storage, or approximately 72,000 full length movies. So you are going to be able to put as much memory on the NAS device as you’re going to need. It will only be a matter of cost that will limit you. And since RAID is very stable, there’s nothing really to be afraid of using this kind of storage. As for whether or not a......

Is there any fault tolerance (such as RAID) build into a NAS device? Are management features available? These are the questions I have to answer for this paper. So, here are my results starting with the first question. What is a NAS device? Network Attached Storage is a storage device connected to a network that allows storage and retrieval of data from a centralized location for authorized network users and heterogeneous clients. Seems to me that a NAS is like a WIFI version of an external hard drive. Though, if needing more room, you can add another to the one you already have. What is the speed of the network adapter available on a NAS device? NAS device doesn’t require much processing power. The largest bottleneck in performance will most likely be the network itself. Most home networks will use wired fast Ethernet (100 Megabits/sec), wired gigabit Ethernet (1000 Megabits/sec), wireless g (54 Megabits/sec), or wireless n (248 Megabits/second). What is the capacity range? Depending on the type and volume of content you plan to store, there's a choice of capacities available all the way up to huge multiple TB (Terabyte) versions.

...Unit 2: Research Paper 1 GS1140 The speed limit is 65 mph and I’m at a stand-still! Why must this happen every morning and afternoon? Traffic will always be an ongoing problem. The more the population grows, the more congested our roads get with more vehicles. Besides leaving hours before traffic starts to avoid traffic jams there has to be another solution. Some solutions include: employee parking cash-out, tolls for single use carpool lanes, and tolls during high peak hours on freeways. An employee cash-out can reduce the amount of vehicles on the road by giving an incentive not to drive (Bullokk, 2011). Companies would give a certain amount each month to the employee who participates in the program. Through data mining, the decrease in the demand of parking can be obtained. The information needed to gather this would be: the number off employees in the program, the financial incentive amount, and the amount of time the incentives were given at separate but equal intervals (Bullock, 2011). A decrease in cars on the road would limit the amount of traffic on the road and also free up precious parking space. Tolls for single use carpool lanes will also benefit in decreasing traffic. The carpool lane is mostly always free of traffic during rush hours which is good for carpoolers, but also counter intuitive. The carpool lane turns into a wasted lane if people are not taking advantage of carpooling. Sensors can be placed in cars to automatically charge the fare for...
