The operating system is an essential component of the system software in a computer system. 3) C.P.U-(central processing unit) is the hardware within a computer that carries out the instructions of a computer program by performing the basic arithmetical, logical, and input/output operations of the system. 4) KB-(kilobyte) is a multiple of the unit byte for digital information. The SI prefix kilo- means 1000. 5) MB- (megabyte) is a multiple of the unit byte for digital information.
RAID 1 –Mirrored set- Creates an exact copy of data on two or more disks c. RAID 5 –Striped set- Parity uses blocked level striping with parity data distributed across all disks in the RAID array. d. RAID 6 –Blocked striped-uses dual parity, crates 2 parity blocks for each data block, handles two disk failures. 4. Why is RAID 0 of any use if it offers no redundancy? RAID 0 gives more storage capacity in that data is spread across multiple.
Memory Management Requirements Your Name POS 355 Date Due Instructor Name Memory Management Memory Management is used to optimize a systems performance through the use of control, coordination, and assignment of blocks of memory used for multiple processes. It is handled through hardware, operating system (OS), programs, and applications. The main goal is to maximize performance. (Rouse, 2012) Memory Management has five basic requirements; 1. Relocation is executing processes separately from physical memory and is handled through paging, partitioning, or segmentation.
(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?
(Choose two answers.) a. Used for short-term memory b. Used for long-term memory c. Used to process data d. Connects to the CPU over a bus using a cable e. Is installed onto the motherboard 5. This chapter describes the concepts behind how a CPU reads the contents from RAM.
While everyone doesn’t have a connection, there are more devices than people and servers to serve content. 5. How long do you think it will take before the IPv4 addresses are completely exhausted? All IPv4 addresses have been allocated to companies. While they have not been assigned to customers they will soon.
2. Chkdsk 3. Disk Defragmenter 4. Configure the paging file 5. Describe, enable, and configure ReadyBoost 6.
Research Process and Terminology Paper Kelli Love CJA/334 July 5, 2015 Greg Moore Research Process and Terminology Paper Every field has its own research process and to be a successful researcher you have to use applied research when working in the criminal justice field. There are some terms in research that apply specifically to the criminal justice field and without this knowledge it will be hard to accomplish your job effectively. The paper focuses on the different terms used, what is research and how it works in the criminal justice field. Terminology The research processed can be categorized as either basic or applied. Basic research looks at the cause, effect and nature of things.
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.
