Again, the capacity range varies for some people have built 40 TB machines and some only have 2TB. With port replication and add-on hard drive controller cards there is hardly a limit on size. As far as fault tolerance, raid 50 is fairly stable if set up correctly, raid 10 is thought to be one of the best setups since more drives can fail at one time without data loss. NAS can be used for sharing files among multiple users / computers. It can also act as an external backup device if needed, thus by using a NAS you can easily get additional or extra storage for all your networked computers which can be quite cost effective in the long run and many NAS devices allow you to add additional space for more storage (Kumar) Now days there are so many different devices being used in our homes from all sorts of mobile devices to a range of gaming devices.
Power saving: both types of computers can hibernate or sleep when not being used. Components: the internal components of a desktop computer are not designed of low power operation. This includes the CPU, which is Vulnerability: both types of computers are vulnerable to malicious code if not properly protected. Communications: Notebooks computers typically have infrared port and built-in video cameras and microphones, whereas these devices are add-nos for desktop computers.

CIS 105 Week 3 DQS CIS 105 DQ 1 There are a variety of computers available, from the smallest computer in a domestic device to the supercomputers used in industry. Despite the different uses for computers, they all have basics elements in common—each computer system involves hardware, software, data, and users. Think about the role of each component of your home or work computer: How do the components of your computer system interact within the system? What improvements or additions to your system do you think would benefit you or make the system more user-friendly?
Memory Management Phillip Schepok POS/355 August 18, 2014 Paul Rouk Memory Management Computers are everywhere. The daily lives of the human population are constantly in use of a computer, or some sort of electronic equipment that is ran from some sort of technological computer. People may not realize that everyday things that help us live our daily lives are surrounded by electronics or computers. The alarm clock to wake you up in the morning, the coffee maker with a timer, the microwave to warm your oatmeal, the television, the automobile, the cellular phone, and the desktop or laptop computer all plays an important factor in our livelihood. To have these working computer electronics one must realize there must be some program to make these products work.
List the six common types of computers available. Mainframe, Server, Desktop, Workstation, Laptop, Handheld 6. Explain what servers are and what they are used for. Servers are high performance computers used in business or other organizations to provide services to many end users. They are used to serve files, programs, web pages, and documents to multiple users.
A word processor may also refer to a stand-alone computer unit similar to a typewriter, but frequently including technological advancements such as a screen, advanced formatting and printing options, and the ability to save documents onto memory cards or diskettes. Word processors almost invariably allowed the user to choose between standard typing and word processing modes by way of a switch. Such word processors should not be confused with an electric typewriter shows the graphical user interface of the Microsoft Word
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.
When dealing with main memory in a computer system you will find that most of the time it is going to be organized in a very linear fashion because this is the easiest way for it to handle tasks that it has. The same can be said of secondary memory as well; however, programs operate in a different way. Programs are broken into pieces called modules that can be referenced in many different orders depending on what has most recently occurred in a program. The order in which modules are called up can even change from one time a program is used to the next. Through the use of logical organization and segmentation an OS and computer hardware can effectively deal with user programs and data in the form of modules, gaining a number of advantages when it comes to memory management requirements (Stallings, 2012).
Think about this when trying to figure where the roles go, It's easier to keep track of FSMO roles if you host them on fewer computers. Place roles on domain controllers that are can be accessed by the computers that need access to a
NTFS file system is used to support larger hard drives and is better for security. You’re able to encrypt and permissions that restrict access by unauthorized users. FAT 32 system files lack the security that NFTS provides. FAT32 allows any user that accesses the machine to view any files without restrictions. FAT32 file systems have a limited amount of disk size.
