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
People would utilize this one more because if one disk would fail, the mirror image of that disk will be on another disk. 6. I would personally choose 0 due to the increase in the speed. 7. The hardware-based system manages the RAID subsystem independently from the host and presents to the host only a single disk per RAID array.
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
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.
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? a.
Answer: When the system has adequate room in RAM for OS applications and data, it does not need to access slower virtual memory on the hard drive as often, which generally makes for a faster system. Which tool on the Kingston Web site could you use to find Kingston modules for your system if you know the model number of your system’s motherboard? Answer: You could use the Memory Search tool. If you were planning to buy a new system, would you choose a motherboard that uses DIMMs or RIMMs? Why?
A user has opened a calculator application typed the numbers 123456789, and then done some math problem using this number. Which of the following determines, in part, what bits the computer stores in RAM to represent the number 123456789? viii. D: The binary equivalent of decimal 123456789. 8.
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.
This password is stored in _______. BIOS CMOS RAM* DDR RAM the CPU 8. (TCO 3) The term form factor in regards to a motherboard refers to the ______ layout of the components on the board physical logical proposed inverted 9. (TCO 9) When you first purchase a notebook, make sure you have a ____ CD containing the installed OS so you can recover from a failed hard drive development management diagnostic recovery 10.

· The ROM BIOS stores the first instruction, which is the instruction to run the power-on self-test (POST). · POST begins by checking the BIOS chip and then tests CMOS RAM. · POST checks the hardware devices (such as the video card), secondary storage devices, such as hard drives and floppy drives,
