Explain the two supported Windows 7 partition styles. What
are the advantages of each partition style? Include in your explanation the
number and type of partitions available with each partition type.
Windows 7 supports two partition
types, Master Boot Record (MBR) and Globally Unique Identifier Partition tables
(GPT).
MBR supports four partitions: three
primary partitions and one extended partition.
MBR supports a maximum volume
size of 2 terabytes.
MBR does not support replication
or CRC.
GPT supports 128 primary partitions.
GPT supports volumes up to 18
exabytes.
GPT supports CRC for increased
reliability.
Explain what is meant by the terms primary partition, extended partition, logical drive, and active partition.
·
Primary partition: Acts as separate disk
space, can host and operating system
·
Extended partition: Cannot host an operating
system, can be subdivided into logical drives
·
Active partition: the primary partition that
hosts the operating system the computer will boot from
What two disk types
are supported in Windows 7?
Basic and dynamic
What are the four volume types available in Windows 7? Explain the advantages and disadvantages of
each.
·
Simple volume: Contains space for a single
disk, can be extended if more disks are added, can be created on basic or
dynamic disks.
·
Spanned volume: Contains space for 2 to 32
disks, all disks must be dynamic, Windows 7 writes to the disk in order (when
disk 1 is full it begins writing to disk 2), can be extended, does not improve
read-write, does not provide fault tolerance.
·
Striped volume: Contains space for 2 to 32
disks, cannot be extended, all disks must be dynamic, system writes data in
stripes across all disks, improves disk performance, does not provide fault
tolerance.
·
Mirrored volume: Contains an equal amount of
disk space for two disks, both disks must be dynamic, each mirrored disk
contains an identical copy of the data, provides fault tolerance, useable disk
space is one-half that of other volume types.
