LESSON 6 Knowledge Assessment Matching: Complete the following exercise by matching the terms with their corresponding definitions. 1. __G___ switched fabric 2. __D___ VDS hardware provider 3. __F___ disk duplexing 4.
5. Describe how a dynamic disk is organized. Page 109 A dynamic disk is organized as a single partition that occupy the entire disk. 6. Describe how raid 1 works and its advantages/disadvantages?
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 the data. Alternatively, if the data matches the machine address, the data is accepted. Since the bus topology consists of only one wire, it is rather inexpensive to implement when compared to other topologies. However, the low cost of implementing the technology is offset by the high cost of managing the network.
MAUs are easy to install and troubleshoot. However, MAUs are more expensive than hubs and switches. In addition, compatible hardware, cables, and NICs are also expensive and not readily available (Ciccarelli, et al 2013). The maximum amount of bandwidth a MAU can support is 16Mbps (Ciccarelli, et al 2013). MAUs can only operate at 4Mbps or 16Mbps which means that you cannot connect a 4Mbps MAU to a 16Mbps MAU (Ciccarelli, et al
Even in regular hard drives can do 80 MBPS. Even in regular hard drives can do 80MBPS, so in theory you could see a bottleneck here, but in practice you probably will be fine. Some disadvantages are a lot of them are external and will use lots of power and because of this it can overload the Power Supply and potentially ruin the Power Supply or the PC may not even start until things are
To use federated search, you must download or create XML files for specific sites called search connectors. 5. The only operating system edition that you can upgrade in place to Windows 7 Professional is Windows 7 Ultimate. 6. Upgrading a computer running Windows 7 starter to Windows 7 ultimate using Windows Anytime Upgrade requires------------------ megabytes of additional hard disk space.
Windows has a Virtual memory manager (VMM) and avoids allocating all the memory until it is absolutely necessary. Windows does prefetching, which is moving pages from the disk to the main memory before it is even needed. Pages that are not needed in the memory are stored into a system called Page file until further need. With the Linux operating system, the files are organized already into the hard drive. This will give speed to Linux and provide for faster
One difference between BIOS and CMOS is that CMOS is written in random access memory (RAM). That is why CMOS is not permanent and may be edited by the user. A battery is required to keep the CMOS configuration settings when the PC is powered down. If the battery becomes low the system tray clock will begin to loos time. If it dies completely or is removed you will get a checksum error during boot up and the process will stop.
+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.
Why is RAID 0 0f any use if it offers no redundancy? Performance is fast with additional storage. 5. Why do you think that RAID 1 can be most expensive? Why would people use it if it’s so costly?
