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.
Running Head: DATABASE ANALYSIS PAPER Database Analysis Paper Michael Corey Ingalls CIS/205 University of Phoenix What Is a Database? Databases are designed to offer an organized mechanism for storing, managing and retrieving information. They do so through the use of tables. If you’re familiar with spreadsheets like Microsoft Excel, you’re probably already accustomed to storing data in tabular form. It’s not much of a stretch to make the leap from spreadsheets to databases.
Unit 2. Assignment 1. Disk Redundancy Research 1. RAID (originally redundant array of inexpensive disks; now commonly redundant array of independent disks) 2. RAID would be used whenever there is a need to manage multiple hard drives.
+CIS305b Test #1 True/False Indicate whether the statement is true or false. F 1. Redundancy wastes space because you are storing the same data in more than one place. T 2. Sharing data is one advantage of database processing.
Crystal Choy Mktg 129 Spring 2015 Case Analysis #1 Autobytel.com Class Analysis The traditional car buying process is that customers will go into a dealership and then the car salesperson and the buyer would be negotiating face-to-face when it comes to purchasing a car. Autobytel took a different approach when it came to selling cars compared to the traditional buying process by offering a website where potential consumers would shop for the automobile online. What is different about this website is that consumers are able to access information about the cars and the prices compared to all the dealerships around the area. Autobytel.com used to be the top of the online referral business in the market. This website was the first online service provided for buyers to shop for cars online so that they do not have to deal with the problems and hassles that arises that traditional buyers would usually deal with when they are at the dealership.
ATM uses fixed size packets (53 bytes) for data communication; frame relay uses variable packet sizes depending on the type of information to be sent. Both information blocks have a header in addition to data block and transfer is connection oriented. Frame Relay is used to connect Local Area Networks (LAN) and it is not implemented within a single area network contrast to ATM where data transfers are within a single LAN. ATM is designed to be convenient for hardware implementation and therefore, cost is higher compared to frame relay, which is software controlled. Therefore frame relay is less expensive and upgrading is easier.
Fault tolerance lessens interruptions in productivity, and it also decreases the chance of data loss. Yes the NAS device is built with Fault Tolerance. Yes there are management features for the person who buys the NAS device is sent with a remote capable of handling the device. A user would more likely need to use this device if they are wanting to share local storage. There are three NAS Devices that are used, The high market Enterprise NAS which is driven by businesses that need to store a huge amount of files, the midmarket NAS is required to accommodate businesses that have several hundred terabytes of data then there is the low end market NAS that is aimed at small businesses and homes users who require local share storage.
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?
The hard disk works sort of like a record: the record (platter) spins on a “spindle” and the arm moves to different sections on the record to read or write to it. By changing the polarity of sections of the record information, stored in binary form. Looking past the mechanical differences, long-term memory serves a similar purpose in computers and humans. Computer hard drives are slow in reading and writing, not unlike human memories, for human memory takes longer to access older memory, computer memory (hard drives) can store unlimited amounts of information for years. Human memories are more changeable than hard drive data,
So pretty much small networks can just be built using just the layer 2 devices and most corporate networks would have to have a mix of layer 2-7. The reason why small networks just use layer 2 is because products are cheap and its and easy way of providing connectivity to small workgroups. Multi-level switches are more expensive and complicated to setup and deploy. All of layer 7 switching is pretty much the SI to make forwarding decisions about HTTP traffic using your information in the URL.. So pretty much dealing with your cookies and websites you visited.
