D. 64 bits per quadruple word. 4. Which of the following answers are true about random- access memory (RAM) as it is normally used inside a personal computer? A. Used for short term memory.
b. The CPU reads all RAM sequentially, beginning with the first byte, until it happens to read the byte that the CPU wanted to read. c. The smallest unit of data that RAM supplies back to the CPU is 1 bit. d. The CPU must first find the file in the file system before reading the data. 6.
RAID 0 gives more storage capacity in that data is spread across multiple. 5. Why do you think that RAID 1 can be the most expensive? Why would people utilize it if it’s so costly? Its disk overhead requires all of its drives to be running.
UNIT 1 ASSIGNMENT 1 1) R.A.M- Stands for (random access memory). This is a type of computer memory that can be accessed randomly. RAM is the most common type of memory found in computers and other devices. 2) O.S.-(operating system) is a collection of software that manages computer hardware resources and provides common services for computer programs. The operating system is an essential component of the system software in a computer system.
Another advantage is Portability. Linux is a generic operating system that can run on different types of hardware from different manufacturers. This allows it to be used in embedded computers as well as microprocessors-based systems and mainframes as well. A third advantage of Linux is its security. Because it is logical based rather than being tied to the hardware, everything is file based, which makes it more secure.
(Choose two answers.) a. Used for short-term memory e. Is installed onto 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?

Which of the following statements is not true of file processing systems? a.|the records in one file relate to the records in other files| b.|they have redundant data| c.|they isolate data| d.|maintenance tasks consume additional time| ____ 15. Which statement does not apply to the database approach? a.|it requires less memory than file processing systems| b.|it increases the data’s integrity| c.|programs are easier and faster to develop than with a file processing system| d.|it allows nontechnical users to access and maintain data| ____ 16. Which of the following DBMSs will run only on a server or mainframe?
RAM is used for temporary storage of data and that data erased after exiting software or rebooting or turning off the computer. Hard disk is permanent storage device for the computer. (Ingberg, 2009) DVD drive is another component that is important for you to install software or store data to a CD or DVD disk. (Ingberg, 2009) There are different types of hardware. There is the
Bhavik Patel POS-355 Week 1 Assignment File Management Paper Memory management is the process to controlling and coordinating computer memory. Memory management is located in the hardware of the operating systems, programs, and the applications of the computer. Memory management is involved different ways in the computer. In hardware, memory management is used in RAM disk, memory cache and solid-state hard drives (SSD). In operating systems, memory management is used to block individual memory change user’s demand.
