The hardware-based system manages the RAID subsystem independently from the host and presents to the host only a single disk per RAID array. Software RAID implements the various RAID levels in the kernel disk (block device) code. It offers the cheapest possible solution, as expensive disk controller cards or hot-swap chassis are not required. Software RAID also works with cheaper IDE disks as well as SCSI disks. With today’s fast CPUs, Software RAID performance can excel
* 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.
D. The binary equivalent to 123456789 8. Which of the following is not a feature of a file system that might be used with a hard disk drive? A.An actuator arm 9. Which of the following are some of the important features supplies by files as defined by a computer OS? (Choose three answers.)A.
List and describe in detail four advantages of Linux. The four advantages of Linux include: a) Affordability, Linux has open source software,meaning that there are no license fees. b) Portability, Linux is a generic operating system that can run on different types of operating systems from different companies. c) Security because it is logical based and everything is file based. d) Multiple users, it can run multiple tasks with many different users at the same time.
Acceptable Use Policy is (UAP) is a written document based on agreement between or among the users of computer in a community for a common good. They also have to promise that they will not violate those rules. This document stipulates on the use including the malpractices or unacceptable uses and the consequences for non-compliance. UAP is mostly used when one is registering intranet. The users may include internet providers for example in a university, school, business or corporations.
More computers cannot be added to the system if there is already 10 users. [pic] Picture shows an example of a peer-to-peer system, as you can see the devices are linked to each other and have no server inbtween them. Peer-to-peer can be in a foam of bus topology, ring topology, mesh topology, star topology and p2p can be a tree topology. The difference between the 2
a. All user devices, wired and wireless, can be up to 100 meters away, but no farther. b. All Ethernet user devices can be up to 100 meters away (but no farther), while WLAN devices can typically be farther away than 100 meters. c. All Ethernet user devices can be up to 100 meters away (but no farther), while WLAN devices must typically be closer than 100 meters.
Timing – synchronization between devices that are communicating so that they each know when the patterns start and end. If one of these elements is not present than communication cannot be established between devices and information cannot be transmitted. Exercise 2.1.2 Characteristics of a modern computer that allow this type of integration is advancement in circuitry that allow it to be installed on the computer as one device or unit. Exercise 2.1.3 Other network services available for installation are UPnP user interface and TCP/IP services Exercise 2.1.4 Since there are no physical connections everything can be done wirelessly. Exercise 2.1.5 The types of connections that are available are wired connection, wireless connection, and dial-up connection.
Copy-on-write data sharing is a feature that is designed yo conserve memory on a terminsal server. 5. A printer is generally not considered to be a component of a terminal. 6. The Remote Desktop Protocol does not carry applicataion data between a terminal server and a client.
Online Social Networks (OSNs) is to give users the capability to manage the messages posted on their own private space to avoid that unwanted content is displayed. A system allowing OSN users to have a direct control on the messages posted on their walls. A flexible rule-based system, that allows users to modify the filtering criteria to be applied to their walls. Machine Learning-based flexible classifier automatically labeling messages in support of content-based filtering. User can post neutral or acceptable content to their private wall.
