ITT Technical Institute ITT Technical Institute Nathaniel Anderson Nathaniel Anderson Unit 8 Short Answer 4.1 Unit 8 Short Answer 4.1 Title: Differentiating Between File Systems Differentiate between File Allocation Table (FAT) 32 and New Technology File System (NFTS). The differences between FAT32 and NFTS is that NFTS is more robust and effective simple because of its advanced features and functionalities. FAT, in general, comprises of overly simplistic data structures, hence making operations more time consuming. NFTS functionalities are far more-over powering since it makes use of advanced data structures to improve reliability, disk space utilization and overall performance. * When it comes to large USB flash drives, the FAT32 file system is the intended primarily used.
Exercise 7.2.1 A dedicated leased line is one of the more expensive solutions to WAN connections, but it provides an always-on connection between two locations. This is incorporated into the local networks at both ends by adding a specialized router to each LAN. What are the benefits of using a dedicated leased line? What are the limitations of using a dedicated leased line? * The benefits are price it’s cheaper than owning a whole WAN.
d. (A) Used for short-term memory. e. (E) Is installed into the motherboard 5. This chapter describes the concepts behind how a CPU reads the contents from RAM. Which of the following is true about the process of read data, as described in the chapter? f. (A) The CPU tells the RAM which address holds the data that the CPU wants to read 6.
The more RAM a computer has, the greater the overall performance. Think of RAM as a human memory, the more things it can remember at once, the more things it can process quickly at the same time. In terms of enhancing graphical images, having more RAM would mean you could open larger file sizes into the software, whilst still running the program at a high, constant speed. Having 2gb of RAM would limit you to only being able to have up to 2gb of access memory. Adobe Photoshop requires at least 2gb to just run, so having anything else open at all would result in your computer running at extremely slow speeds or even crashing.
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.
Also we know that more processes running on your computer will in general mean less CPU’s horsepower available for other tasks. This means you should first have a look at the running services on your computer and determine if they are really necessary. For example is it really necessary that your TomTomHOMEService used for ejecting TOMTOM devices runs automatically or can you may be set it’s start up type to manual in the Windows 7 in Control Panel > System and Security > Administrative Tools > Services list? A less obvious factor which can affect your computer’s performance is the fragmentation on the hard disk drive, making it more difficult for the system to build up the data it needs to run you applications in memory if the composite data are scattered all over the hard disk drive. In the System Section under the Control Panel in Windows 7 is a section called “Check the Windows Experience Index” which is a nice step up from the situation

Final Exam Chapter 6 1. Parity is used with RAM for ______________. Answer: Error Checking 2. What type of RAM does not need to be refreshed? Answer: Static Ram 3.
W1A1 Megan Murphy Herzing University Personal computers consist of a main processing unit, the keyboard, mouse, RAM, hard disk, DVD drive, and monitor to make it functional. The keyboard is used to input your words, information, and commands into the computer. The mouse is used to navigate around the screen. RAM or random access memory is a memory component. RAM is used for temporary storage of data and that data erased after exiting software or rebooting or turning off the computer.
