NT 1230 Client Server Networking Unit 2 Assignment 1 Disk Redundancy Research Unit 2 Assignment 1 Disk Redundancy Research 1. What does RAID stand for? Redundant array of independent disks 2. When would you use RAID? RAID’s are useful in large file servers, transaction of application servers, where data accessibility is critical, and fault tolerance is required.
Next tool on our list is the disk defragmenter tool. This tool moves the clusters of a hard drive to make one continuous cluster. When a program is deleted off of a machine is fragments the harddrive leaving the clusters in different parts of the harddrive when a defrag is ran it takes all the fragmented clusters and makes them all one. You can run this manually by performing the following steps. Click Start, and then click Computer.
Exercise 7.2.1 A dedicated leased line is one of the more expensive solutions to WAN connections, but it provides an always-on connection between two locations. This is incorporated into the local networks at both ends by adding a specialized router to each LAN. What are the benefits of using a dedicated leased line? What are the limitations of using a dedicated leased line? * The benefits are price it’s cheaper than owning a whole WAN.
Technically RAM does not have an influence on the processor performance, but it does have an influence on how much processes or technically instructions that processor can read. So a greater amount of RAM memory means that more instructions fit into that memory and therefore, bigger programs can be loaded at once. (Computer) Allowing the operating system to work with a multitasking concept, where we can run multiple programs at once. To explain how it works, you have 128MB of RAM on your computer and you need to load up multiple programs that are 512MB. That means you would have slowness as it has to load a piece of that program, then it has to refresh, then load up the rest of the program.
Which of the following statements is not true of file processing systems? a.|the records in one file relate to the records in other files| b.|they have redundant data| c.|they isolate data| d.|maintenance tasks consume additional time| ____ 15. Which statement does not apply to the database approach? a.|it requires less memory than file processing systems| b.|it increases the data’s integrity| c.|programs are easier and faster to develop than with a file processing system| d.|it allows nontechnical users to access and maintain data| ____ 16. Which of the following DBMSs will run only on a server or mainframe?
Fiber cabling is growing very fast due to how much more efficient it is than copper cabling. Fiber, for one, has a greater bandwidth. Single mode cables offer the most bandwidth but you have the option of the single mode, 62.5 or 50 micron multimode cables. In addition to that, fiber can carry more information than the copper. Fiber can also carry over a longer distance with low attenuation.
In today's world, MAC is becoming more of a trend among people, they are cool and fast machines. MAC is a great computer, if you can afford them. Macs are extremely expensive, and you can honestly do less with them. You get more bang for your buck choosing a PC, and they are less expensive. With PC, you have a better gaming computer, video and audio editing, and 3D editing.
MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question. 1) A good definition for a database is: 1) _______ A) A text file with values delimited by commas B) A collection of related data C) A card catalogue D) A piece of software for managing databases 2) Redundancy refers to what database condition? 2) _______ A) All data is stored in tables B) You have more than one database devoted to the same thing C) The same data is recorded in more than one place in the same database D) A primary key is repeated in another table as a foreign key 3) Which best defines the function of a primary key? 3) _______ A) It uniquely identifies each record B) It is always a number C) It unlocks the data in a table D) It is the first field in a table 4) What best describes the function of a foreign key?
NT1110 Computer Structure and Logic Chapter 6: Memory and Storage 1. A computer storage location that allows information to be stored and accessed quickly from random locations within the DRAM (Dynamic Random Access Memory) on a memory module. 2. A page file is stored on the computer hard drive that is used as a temporary location to store information that is not currently being used by the computer RAM. 3.
Unit 6 Research Paper Frederick The NAS Device NAS is often manufactured as a a specialized computer built from the ground up for storing and serving files, more than the general computer that we use for our own purposes. In 2010 the popularity of the NAS Device started to really hit off for transferring data from one computer to another. The awesome thing about the NAS devices is that it doesn’t limit storage usage to a single computing device. 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. The capacity range for the most updates NAS device is the QNAP Turbo NAS TS-470.
