Hardware chapter 7 and 8 part 1

A simple problem of replacing a bad memory module can become a complex research project if you don't nave a good grasp of current and past memory technologies
Systems using RIMMs are still being used.
Mixing unbuffered memory with buffered or registered memory will work but is not recommended.
Most often, placing memory on the motherboard and updating the BIOS manually is all that is necessary for installation
For most SIMMs, the module slides into the slot at an angle.
A hard disk drive (HDD) , most often called a hard drive, comes in two sizes for personal computers; the 1.8" size is used for laptop computers and the 2.5" size is used for desktops.
Almost all hard drives sold today for desktop computers are magnetic hard drives.
Solid state hard drives cost more and are less rugged than magnetic hard drives.
If you are replacing a floppy drive, you must inform BIOS setup by accessing setup and changing the drive type.
Hardware problems usually show up at POST, unless there is physical damage to an are of the hard drive that is not accessed during POST.
_____ memory temporarily holds data and instructions as the CPU processes them.
Random access
RAM is divided into two categories, _____.
_______ is used for a memory cache and is contained within the processor housing.
_____ loses its data rapidly, and the memory controller must refresh it several thousand times a second.
dynamic RAM
RAM on motherboards today is stored on ____.
Laptops use smaller versions of a DIMM called _____
A _______ gets it name because it has independent pins on opposite sides of the module.
DIMMs intended to be used in server must be extremely reliable and use an error-checking technology.
If the number of bits is not an odd number for odd parity or an even number for even parity, a ___ error occurs.
A Rambus memory module is called
SIMMs are rated by speed, measured in ____
When windows does not have adequate memory to perform an operation, it gives a _____ error or its slows down to a painful crawl.
Insufficient Memroy.
To upgrade memory means to add more ___ to a computer.
To use System Information, in the Vista Start Search box or the Windows XP Run box, type ____ and press Enter
In the table found in the motherboard manual, a chip on a RIMM module is called a ____.
Higher-quality memory modules have ____ installed to reduce heat and help the module last longer.
heat sinks
If the chip's surface is dull or matted, or you can scratch off the markings with a fingernail or knife, suspect that the chip has been ____.
re marked
For ____ modules, small clips latch into place on each side of the slot to hold the module in the slot.
For RIMM modules, install the RIMMs beginning with bank ____.
When installing the RIMM, ____ on the edge of the RIMM module will help you orient it correctly in the socket.
In Windows, memory errors can cause frequent ____ errors.
general protection fault
A ____ drive 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.
magnetic hard
The top and bottom of each disk of a magnetic hard drive have a(n) ____ that moves across the disk surface as all the disks rotate on a spindle.
read/write head
Each side, or surface, of one hard drive platter is called a ____.
Windows Vista technology that supports a hybrid drive is called ____.
ready drive
The total number of ____ on the drive determines the drive capacity.
_ on a circuit board inside the drive housing is responsible for writing and reading data to these tracks and sectors and for keeping track of where everything is stored on the drive.
During the ____ formatting process, you specify the size of the partition and what file system it will use.
high level
The ATA interface standards are developed by Technical Committee T13 and published by ____.
____ is 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.
The ____-conductor IDE cable has half the number of pins as it has wires.
____ transfers data directly from the drive to memory without involving the CPU.
___ mode involves the CPU and is slower than DMA mode.
With ____, you can connect and disconnect a drive while the system is running.

External ____ is up to six times faster than USB or FireWire.
____ is a standard for communication between a subsystem of peripheral devices and the system bus.
