Answer:
usable capacity = 10 GB
Number of cylinders = 256
Block size = 4 KB
(1)Bytes in each cylinder = (10*230)/(256) = (10*222) = 40 MegaBytes
(2)Number of Blocks in each cylinder = (10*222)/(212) = 10K
(3)capacity of one track = 40 MegaBytes/(10*2) = 2 MB
Rotation speed = 3840 RPM
Number of rotations per second = 3840/60 = 64
Transfer rate = (2*64) = 128 MB/sec
Explanation:
<span>
C. The net charge does not change. The charge remains neutral and thus,
polarization takes effect. Polarization simply means electrons and protons are separated into opposites. To best explain this, we can use a rubber balloon that has been rubbed against animal fur. Assume is has been negatively charged, bring it close to the object and make sure that these two do not touch. Electrons within the object will experience a repulsive force.
</span>
Since repulsion will be greatest for those
electrons nearest the balloon, many of them will be induced into moving away
from the rubber balloon. By default, electrons are free to move from atom to
atom and thus there will be a mass migration of balloons side of the object to
the opposite side of the object. <span>This will leave more atoms on the rubber
balloon’s side of the object with a shortage of electrons and will be
positively charged and vice versa. </span>Overall, the object will become
electrically neutral.
Answer:
Application software
Explanation:
There are two types of software: application software and systems software. Systems software focuses on managing the computer itself, like file managing applications, DOS, etc. Application software is for the users of the device. Examples include a media broadcaster, like Netflix, a video game, email services, and of course, word processor.
If you're looking for examples of word processing software, these include Microsoft Word, Google Docs, Pages, etc.
Answer:
A) The type of data it will hold
Explanation:
In most programming languages, a variable must be decalared before it can be used. Variable declarations allows the compiller to make provision of memory space for the variable so the type of data must be defined accordingly with the name of the variable because different data types occuppy different spaces in memory for example
An integer is 32 bit integral value
A char is 16 bit unicode value
A double is 64 bit floating point value
