Which of the following answers best describes how a hard disk drive physically writes a binary 0 or 1?C. changing the disk’s surface 12. Which of the following answers are true about an internal hard disk drive (HDD) as it is normally used inside a personal computer (choose 2) B. used for long-term memory, D. connects to the CPU over a bus using a cable
Used for short term memory. 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?
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.
(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?
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.
8) U.S.B. - (Universal Serial Bus) is an industry standard developed in the mid-1990s that defines the cables, connectors and communications protocols used in a bus for connection, communication, and power supply between computers and electronic devices. 9) H.D.D.-(Hard disk drive) is a data storage device used for storing and retrieving digital information using rapidly rotating disks coated with magnetic material. HDD retains its data even when powered off. Data is read in a random-access manner, meaning individual blocks of data can be stored or retrieved in any order rather than
NT1110 Computer Structure and Logic Chapter 6: Memory and Storage 1. A computer storage location that allows information to be stored and accessed quickly from random locations within the DRAM (Dynamic Random Access Memory) on a memory module. 2. A page file is stored on the computer hard drive that is used as a temporary location to store information that is not currently being used by the computer RAM. 3.
It still uses a small battery incase there is a power outage and still uses volatile RAM. Has the size of the CMOS memory increased, decreased, or stayed the same? The size of the CMOS memory has also pretty much stayed the same because there is no need to increase the size. There was never any need to store more than 512 bytes in the memory as it holds the absolute basic boot settings for the system. The typical size is still 512 bytes currently.
Which of the following is true about the process of read data, as described in the chapter? The CPU tells the RAM which address holds the data that the CPU wants to read. 8. Which of the following is not a feature of a file system that might use with a hard disk drive? An actuator arm 13.
3. Provide a comparison table showing the similarities and differences between desktop and notebook computers. Task1: Here are the functions of the each component in the Von Neumann model of the computer Component Function Control unit The control unit will manage the process of moving date and program that data. In modern computers this memory is RAM. Arithmetic logic Unit This part of the architecture is solely involved with carrying out calculations upon the date.
