Lab 7.2 Is a DIMM or RIMM more expensive, given that both hold the same amount of memory? Why do you think the price varies? Answer: A RIMM is more expensive because RAMBUS holds patent rights to the technology, and the manufacturer must pay royalties to RAMBUS. Summarize why adding RAM offers a performance advantage. Answer: When the system has adequate room in RAM for OS applications and data, it does not need to access slower virtual memory on the hard drive as often, which generally makes for a faster system.
It depends on why I need the RAID. If had a type of high traffic situation I would use, RAID 0 with a high speed situation, and I would use RAID 1 if I needed high availability. 7. What is the difference between software RAID and hardware RAID? Hardware RAID requires specialized hardware to handle the drives and is more reliable compared to software RAID.
* When it comes to large USB flash drives, the FAT32 file system is the intended primarily used. The reason that FAT is used is because FAT can be used on both operating systems, Windows and iOS, and NFTS cannot be used on non-window systems. * Which file system provides support for larger hard drives and better security in the form of encryption and permissions that restrict access by unauthorized users? NFTS is the required file system for large hard drives, because you are able to give it better security than the FAT. With FAT and if you are using Windows 7 then your files can be read unlike the NTFS.
RAID would be used whenever there is a need to manage multiple hard drives. 3. RAID 0 (also known as a stripe set or striped volume) splits data evenly across two or more disks (striped), without parity information and with speed as the intended goal. RAID 1 consists of an exact copy (or mirror) of a set of data on two or more disks; a classic RAID 1 mirrored pair contains two disks. RAID 5 consists of block-level striping with distributed parity.
Which of the following is NOT one of them? a. Directory Services c. Network Services b. Infrastructure Services d. Application Services ____ 8. Distributing server roles among several computers has several distinct advantages, including which of the following? a. fault tolerance c. resource allocation b. scalability d. all of the above ____ 9. What capability of the File Services role consists of two role services that allow administrators to create a virtual directory tree consisting of folders stored on different servers and to maintain duplicate copies of that information?
With an information-centric storage system the information can be shared amongst different departments and areas and also helps to prevent duplication, while providing better redundancy and reliability with dynamic systems that can be repaired and upgraded without the downtime on a server-centric storage system. 3. What are the attributes of big data? Research and prepare a presentation on big data analytics. Big data is any data that isn’t able to be handled by commonly accepted methods of data processing, whether it is database management systems, processing and search

To clean up files on your hard drive: 1) Choose Start Control Panel System and Security. The Administrative Tools window appears.2) Click Defragment Your Hard Drive. The Disk Defragmenter dialog box appears.3) Click the Analyze Disk button. This step checks whether your disk requires defragmenting. A drive with 10 percent or more fragmentation should be defragmented.4) When the analysis is complete, click the Defragment Disk button.
What is LVM? What advantages does LVM have over traditional partitions? It allows you to manage logical volumes in a single partition, but more importantly, it allows you to shrink or expand them while the system is up and running. 8. What is a mount point?
