1.Describe the different types of storage devices . - Magnetic
storage devices Today, magnetic storage is one of the most common
types of storage used with computers and is the technology that
many computer hard drives use - Optical storage devices Another
common storage is optical storage, which uses lasers and lights as
its method of reading and writing data. Storing data online and in
cloud storage is becoming popular - Flash memory devices Started to
replace magnetic media as it becomes cheaper and more efficient
solution. - Online and cloud as people need to access their data
from more than one device. - Paper storage Punch card Early
computers had no method of using any of the above technologies for
storing information and had to rely on paper. Today, these forms of
storage are rarely used or found. 2. Define The FollowingA. Hard
Disk Latency - is the time it takes for the selected sector to be
positioned under the read/write head. Channel latency is the time
it takes for a computer channel to become unoccupied in order to
transfer data. Network latency is the delay introduced when a
packet is momentarily stored, analyzed and then forwarded. B. Hard
Disk Transfer Rate - is commonly used to measure how fast data is
transferred from one location to another. For example, a hard drive
may have a maximum data transfer rate of 480 Mbps, while your ISP
may offer an Internet connection with a maximum data transfer rate
of only 1.5 Mbps. C. Disk Optimization - A program that makes a
disk more efficient. Disk optimizer us a variety of techniques,
including defragmenting the disk. Fragmentation occurs naturally
when a disk is used often. D. Disk Defragmentation - is the process
of consolidating fragmented data on a volume (such as a hard disk
or a storage device) so it will work more efficiently.
Fragmentation happens to a volume over time as you save, change, or
delete files.
