How is data stored on a hard disk?

The info is stored in ASCI format. 8 bit Bytes in a magnetic field. Each bit is either turned on or off. ( 0 or 1 ) for ex 36 = 0010 0100. Every letter or number and special characters have an ASCI number.

C is the best answer. 0 and 1 are stored by a magnetic ploarity setting of North or South.

The drive these 0 or 1's are stored in sectors on the drive .

a low level format is like paving the parking lot

a high level format is like painting the lines for the cars (data)

and the fat table tells where all the cars (data) are parked

the data is stored as a magnetic positive or 1

or no magnetic data a 0

the bytes and bit stuff is a little more detailed so here is the low down.

definite, yet no longer quickly. a pair of issues that would - might - impression throughput - fragementation - in case you have, or HAVE HAD, quite a few records over a volume of time, those records - as they're deleted and re-created - might tend to create "holes" of unallocated sectors. whilst the filesystem ("laptop") tries to study a record, it would "hop over" those holes to attain the added ends of the record. Run a defrag application for this. actual area - in case you have incredibly some information on your disc, then many records will certainly lie on the some distance end of the disc. It takes longer for the readwrite head(s) on the disc to shuttle to those records than it does to shuttle to the records that are closest to the pinnacle reset place. Neither of those issues impacts "laptop sspeed" per se - your cpu chip is working merely as rapid because it did until now. yet, if the cpu has to look ahead to the disc to hop around a hollow, or shuttle some distance to get a record, then it may "look" that the laptop is slowing down. And returned, those issues (and others no longer pronounced) may be ameliorated in great degree by potential of such record equipment artifacts as caching and/or study forward.

?~!, we are on to you. Very clever. You are cutting and pasting with lots of different questions to score points. Good idea.

The answer is C.

c

the answer is c
