A drive that has no moving parts with nonvolatile flash memory. Similar to USB flash drives.
Magnetic Hard Drive
A drive which has one, two, or more platters, or disks, that stack together and spin in unison inside a sealed metal housing that contains firmware to control reading and writing data to the drive and to communicate with the motherboard.
The top and bottom of each disk have a __________ that moves across the disk surface as all the disk rotate on a spindle.
Windows Vista technology that supports a hybrid drive is called ___________.
Track and sector markings are written to a hard drive before it leaves the factory in a process called _____________.
A single hard drive that works independently of other hard drives.
The one bootable partition.
During this process, you specify the size of the partition and what file system it will use.
Primary Partition (Volume or Simple Volume)
This volume is assigned a drive letter (such as drive C: or D:) and is formatted using a file system.
The overall structure on OS uses to name, store, and organize files on a drive.
The smallest unit of space on a disk for storing a file and is made up of one or more sectors.
One of four partitions that can be divided into one or more logical drives.
A drive assigned a drive letter (such as G:)
File Allocation Table (FAT)
A table on a hard drive or floppy disk that tracks how space on a disk is used to store files. It has storage limitations concerning hard drive size, volume size, and file size.
New Technology File System (NTFS)
A file system designed to provide greater security and to support more storage capacity than the FAT32 file system.
Parallel ATA (PATA), Serial ATA (SATA), and SCSI
The three current methods used by internal hard drives.
American National Standards Institute
S.M.A.R.T. (Self Monitoring Analysis and Reporting Technology
A system BIOS feature that monitors hard drive performance, disk spin up time, temperature, distance between the head and the disk, and other mechanical activities of the drive in order to predict when the drive is likely to fail.
Also called the EIDE (Enhanced IDE) standard, allows for one or two IDE connectors on a motherboard, each using a 40-pin data cable.
An EIDE drive such as a CD or DVD drive must follow the ____________ standard in order to connect to a system using an IDE connector.
80-Pin conductor IDE cable
A cable with 40 pins and 80 wires. Forty wires are used for communication and data, and an additional 40 ground wires reduce crosstalk on the cable.
Direct Memory Access (DMA)
_____ transfers data directly from the drive to memory without involving the CPU.
Programmed Input/Output Transfer (PIO)
_____ mode involves the CPU and is slower than DMA mode.
Serial ATA (SATA)
These interfaces are much faster than PATA interfaces and are used by all types of drives, including hard drives, CD, DVD, Blu-ray, and tape drives.
Hot-Swapping or Hot-Plugging
With this, you can connect and disconnect a drive while the system is running.
Each device on the bus is assigned a number from 0 to 15 called the _______, by means of DIP switches, dials on the device, or software settings.
SCSI ID 7
The host adapter is assigned SCSI ID ___, which has the highest priority over all other devices.
Logical Unit Number (LUN)
A number assigned to a logical device (such as a tray in a CD changer) that is part of a physical SCSI device, which is assigned a SCSI ID.
To reduce the amount of electrical "noise," or interference, on a SCSI cable, each end of the SCSI chain has a __________.
A type of SCSI technology where you can connect up to 126 devices together on a single Fibre Channel bus.
RAID (Redundant Array of Inexpensive Disks)
Technology that configures two or more hard drives to work together as an array of drives.
A computer's ability to respond to a fault or catastrophe, such as a hardware failure or power outage, so that data is not lost.
This RAID number uses space from two or more physical disks to increase the disk space available for a single volume.
This RAID number is a type of drive imaging. It duplicates data on one drive to another drive and is used for fault tolerance.
This RAID number stripes data across three or more drives and uses parity checking, so that if one drive fails, the other drives can re-create the data stored on the failed drive. (Data is NOT duplicated)
Two hard drives are configured as a single volume. Data is written to the first drive, and when it is full, the data continues to be written to the second drive.
Boot Sector (Boot Record)
The first sector on the disk. Contains the information about how the disk is organized and the file system used.
Floppy drives are always formatted using this system.
After a floppy drive is installed, you must configure the drive in ______ setup.
Other name for FireWire
UART (Universal Asynchronous Receiver)
The controller logic on a motherboard that manages serial ports.
Standard Parallel Port (SPP); Enhanced Parallel Port (EPP); and Extended Capabilities Port (ECP).
Parallel ports fall into one of these 3 categories
