Answer:
A tape drive provides sequential access storage, unlike a hard disk drive, which provides direct access storage. A disk drive can move to any position on the disk in a few milliseconds, but a tape drive must physically wind tape between reels to read any one particular piece of data.
Explanation:
Architecturally tape drives are sequential storage, meaning that if you need to access some data at the end of the tape you needed to seek to the end and retrieve it. This can take seconds or minutes. Disks, OTOH are random access. Some hard drives use rotating media and movable heads , so the seek times are instantaneous , at least compared with tape drives. However, like tapes, there is a big advantage to using a rotating hard drive as sequential storage. It takes time, measured in milliseconds, for a head to move to another track. So traditionally, random access is much slower than sequential access.
SSDs have no internal moving parts so random access occurs in the same time frame as sequential access. Moreover, these drives usually have very high performance. For example, they can saturate a SATA data link, meaning that the SATA connection to the motherboard is now a bottleneck in disk access.
At one time tape drives were very popular. They were a low-cost alternative to using disks as backup. They were especially useful when IBM invented the Winchester “fixed” drive. This meant that the hard drive is fixed within its enclosure like they are today. Prior to this one could remove the drive pack and replace it. This was helpful when upgrading to a new version of the operating system as it was simple to replace the older drive pack should there be a problem.
Tape drives can be used in larger data centers, due to the fact that tape volumes can be removed and replaced so that the actual tape drive can backup many disk sets. Also the tape volumes can be stored off-site or in a fire-proof vault so this is valuable in a data recovery scenario.
Answer:
Sorry mate I tried but I got it wrong
Explanation:
Sorry again
Along with an IP address, a subnet mask, and a name server, the other thing required for a computer to operate on a network is a primary gateway. The primary gateway acts as an access point which forwards information to another network or the internet.
<u>Answer:</u>
<em><u>Static positioning</u></em><em> positioning is used to nudge an element out of its normal position in a document flow.</em>
<u>Explanation:</u>
<em>There are 3 types of positioning in HTML / CSS. Positioning is normally how an element is placed in the document. </em>
- The first type of positioning is the <em>static positioning</em> where the position is set at the time of page load and this is the default type of positioning.
- The next one is the <em>relative positioning</em>, which works very similar to the first one, but the position differs according the value provided. It keeps changing.
- The last one is the <em>absolute positioning</em> removed from normal position in a document flow.
