Internet Research or Library Research

...Internet Research or Library Research Abstract Does internet research promote laziness or does it save time? Judith Levine’s article I Surf, Therefore I Am would suggest that the internet is full of garbage and is a useless tool. While reading books, magazines, and newspapers are still available they do come at a cost. However, in the right hands the internet can be a treasure chest full of valuable information. Internet Research or Library Research Where do you go when you have a research paper due? Do you spend countless hours at the neighborhood library combing through endless rows of dusty books or do you go to your personal computer, open up the internet and go to your trusty internet search engine? Like most people today, I would prefer spending my research time at home surfing the World Wide Web for my results. Not only is this a better use of my time as I am sure is the case for many other students, but unlike those that live in large cities I do not have local access to a state of the art library facility. In addition to the internet providing information literally at your fingertips, it also provides instant access to needed information. Unlike Levine, many people do not have access to library facilities as well provided for as the NY Science, Industry, & Business Library. Like myself, there are many who live in small towns with libraries that very frequently do not have the latest best sellers never mind them having adequate material required......

Unit 6 Nt1110 Memory Cost

...Donshay Clark 7-22-13 NT1110 Unit 6 Analysis 2: Memory Cost 1. Your OS will use the hard drive as a "swap file" or virtual memory, if your PC runs out of RAM while you are working away. Using your hard drive as memory causes a serious performance hit, as hard drives are slower than RAM. You must have enough memory, adding more does not help if you are not doing anything that needs more memory. Today, a modern PC and a modern OS need about 4 gigs to achieve this for most standard users. You want enough RAM so the OS doesn't start using the hard drive as memory. 2. The user with the three 200 GB hard disks has the advantage, because he can utilize all three disks simultaneously, while the other one can only use that single disk. The user with the three disks will probably be able to do more, faster. 3. A typical home computer user would require RAID technology if they use their computer as a home office and have data that is invaluable or irreplaceable. The option is becoming more popular because of the speed increase, and or data reliability you achieve when you set RAID up. A typical business user would use RAID to provide data redundancy, fault tolerance, increased capacity, and increased performance. Data redundancy protects the data from hard drive failures. This benefit is good for companies or individuals that have critical or important data to protect, or just anyone that's paranoid about losing data. Fault tolerance goes hand in hand with......

...NT1110 Unit 4 Research Paper Student NT1110 Abstract Components and technology of today’s computer motherboards. This paper will give a brief description of chipsets, Motherboard bus’s, & Component Integration. NT1110 Unit 4 Research Paper The chipset on today’s computers is responsible for managing the flow of information between the CPU, Memory, & the Peripherals. Chipsets are usually deigned to work with a specific family of microprocessor such as Intel or AMD. Mother board Buses can be broken down into two different types, the first type is the internal bus. The internal bus is easily recognized by the gold lines of wire that run throughout the motherboard. The external buses are the slots filled with pins on the motherboard. Both types of bus are basically the lines of communication for the mother boar. There are six major types of external buses on a common motherboard, only a few of these are found on the mother board of a home PC, they are PCI, AGP, USB, & IDE. The external Buses connect to the Internal bus via the pins in there Appropriate slots, those pins transfer the information from the external buses to the internal bus and then to the final destination. The final topic of this paper is component Integration, component integration has eliminated the need for individual component hard ware and the heat they produce. The elimination of those two things has enabled the manufacturers to reduce the size of today’s computers enabling the......

Unit 5 Assignment 1: Video Summary 3 Cpus Nt1110

...Fredrick Donaldson Nov.5, 2014 NT1110 Unit 5 Assignment 1 Video Summary 3 CPUs In today’s market there are 2 main manufacturers of CPUs: Intel and AMD. There are also some smaller competitors that manufacture CPUs, but they tend to come and go. The way a CPU is organized varies, but here are the basics: The motherboard system bus carries information into and out of the CPU. When the system bus enters the CPU, it’s called a Front side bus. The Front side bus usually uses a 64-bit wide data path. On the side of the CPU you will find a controller. A controller manages the basic functions of the CPU, and controls communication between the motherboard and other components within the CPU. These other components includes one or more ALUs and internal cache. An ALU (Arithmetic Logic Unit), is responsible for solving complex calculations. Having multiple ALUs in a single processor is what gave the early Pentiums their multi-processing capabilities. Communication between the controllers and the ALU uses a 32-bit wide internal data bus. The bus system that supports communication between the cache, the ALU, and the controllers is referred to as the backside bus. The most important thing a person needs to know about a processor is the speed at which it processes information; (CPU speed). There are several ways to gauge CPU speeds. This may sound like an advantage, but oftentimes, these multiple ways are misleading. The speeds differ inside and outside the processor. Internally...

Nt1110 Unit 7 Research Paper 1 Uefi Bios.Docx

...Unit 7 Research Paper 1: UEFI BIOS 1. UEFI BIOS - is a specification that defines a software interface between the operating system(s) and the platform's firmware. In the mid 90s Intel was creating a new processor architecture that was 64-bit, but wasn't backwards-compatible with the old x86. This architecture was the Itanium 64. Because the IA-64 only supports 64-bit instructions, the PC BIOS couldn't be used, therefore Intel developed the EFI specification. Later on this specification was managed (and still is) by the UEFI board, an association of several companies such as AMD, Microsoft, Intel, Apple and so on. History - UEFI is actually an extension of the original Extensible Firmware Interface developed by Intel. They developed this new hardware and software interface system when they launched the ill-fated Itanium or IA64 server processor lineup. Because of its advanced architecture and the limitations of the existing BIOS systems, they wanted to develop a new method for handing off the hardware to the operating system that would allow for greater flexibility. Because the Itanium wasn't a huge success, the EFI standards also languished for many years. In 2005, the Unified EFI Forum was established between a number of major corporations that would expand upon the original specifications developed by Intel to produce a new standard for updating the hardware and software interface. This includes companies such as AMD, Apple, Dell, HP, IBM, Intel, Lenovo and Microsoft...

...Unit 6 Research Paper 1 Network Attached Storage ITT Tech Network attached storage (NAS) is basically a server that acts as hard drive that’s attached to a network. This connection to a network allows anyone who is also connected to the network the ability to access the hard drive. The NAS come in many sizes and different capabilities. The network connection that the NAS uses can be almost any that are available. The standard Ethernet connection is the most common connection by there are also systems that use a wireless connection or even a fiber optic connection for extremely fast transfer speeds. The storage of NAS systems can vary greatly. There are consumer models with a fixed amount of storage, and then the professional versions that have the capacity of many terabytes that can be upgraded when new drives become available. With the numerous amount of drives the chance of corrupted data and errors is always a possibility. With this possibility manufacturers have included the ability to arrange the drive into a RAID. The different RAID configurations allow users the protection from errors and data loss at the expense of storage space. NAS, unlike normal servers, do not require a keyboard, mouse, or monitor. They are usually managed from a remote terminal accessed via the NAS network connection. Some NAS systems use a web browser interface that uses the user’s web browser to interact with the NAS. Other systems use software that the manufacturer......

...Unit 10 Research Exercise Josue Tagle ITT Technical Institute NT-1110 1-What exactly is electrostatic discharge (ESD)? Electrostatic discharge (ESD) is the sudden flow of electricity between two electrically charged objects caused by contact, an electrical short or dielectric breakdown. A buildup of static electricity can be caused by tribocharging or by electrostatic induction. The ESD occurs when differently-charged objects are brought close together or when the dielectric between them breaks down, often creating a visible spark. 2-Perform the following research about the CompTIA’s Six Steps to troubleshooting, explain EACH step in DETAIL: Step 1: Identify the Problem In this first step you already know that there is a problem; now you have to identify exactly what it is. This means gathering information. You do this in a few ways: Step 2: Establish a Theory of Probable In step 2 you theorize as to what the most likely cause of the problem is. Start with the most probable or obvious cause. For example, if a computer won’t turn on, your theory of probable cause would be that the computer is not plugged in! This step differs from other troubleshooting processes in that you are not making a list of causes but instead are choosing one probable cause as a starting point. In this step you also need to define whether it is a hardware- or software-related issue. Step 3: Test the Theory to Determine In step 3 take your theory from step 2 and test it.......

I made it through the first 14 years of my education thumbing through library card files and magazine reference books. In my mind, a big stack of books and articles was the only sign of thorough research. I feared Internet research for the same reason that my mother hated microwave ovens (at least until she had the chance to use one). The Internet was a strange, foreign world to me. Like my mother and her microwaves, I feared it because I did not understand it. However, my mother has learned to love her microwave, and becomes testy if for some reason she can't use it. Maybe there's hope for me, after all. I did possess a smattering of knowledge about the Internet. My feeble attempts to locate long-lost friends yielded an awareness of some sites called "Yahoo!", "Excite!" and "Lycos!". I knew that if I typed in a word or two, then clicked on the word "Search", that a listing of references would pop up. Attached to these references were some obscure foreign hieroglyphics that usually started out with something like "http:\\%$@@!!"

Unit 3 Research Assignment 1

...Unit 3 Research Assignment 1 Exploring Reverse Engineering Reverse engineering can be viewed as the process of analyzing a system to: 1. Identify the system's components and their interrelationships 2. Create representations of the system in another form or a higher level of abstraction 3. Create the physical representation of that system. Reverse engineering is very common in such diverse fields as software engineering, entertainment, automotive, consumer products, microchips, chemicals, electronics, and mechanical designs. For example, when a new machine comes to market, competing manufacturers may buy one machine and disassemble it to learn how it was built and how it works. A chemical company may use reverse engineering to defeat a patent on a competitor's manufacturing process. In civil engineering, bridge and building designs are copied from past successes so there will be less chance of catastrophic failure. In software engineering, good source code is often a variation of other good source code. Reverse engineering enables the duplication of an existing part by capturing the component's physical dimensions, features, and material properties. Before attempting reverse engineering, a well-planned life-cycle analysis and cost/benefit analysis should be conducted to justify the reverse engineering projects. Reverse engineering is typically cost effective only if the items to be reverse engineered reflect a high investment or will be reproduced in large......
