•A measuring instrument may be a device to degree a
physical amount. Established standard objects and
occasions are utilized as units, and the method of
estimation gives a number relating the thing beneath
think about and the referenced unit of estimation.
Measuring rebellious, and formal test strategies which
characterize the instrument's utilize, are the implies by
which these relations of numbers are obtained.

within the computer
system. The term memory
recognizes data storage that
comes within the shape of
chips, and the word
capacity is utilized for
memory that exists on
tapes or disks

MEMORY
5. • Refers to how much disk space
one or more capacity gadgets
gives. It measures how much
information a computer system
may contain. For an example, a
computer with a 500GB difficult
drive encompasses a capacity of
500 gigabytes. A organize server
with four 1TB drives, contains a
capacity of 4 terabytes.

DATA STORAGE CAPACITY
6. • A coordinates electronic circuit
that performs the calculations
that run a computer. A
processor performs
arithmetical, coherent,
input/output (I/O) and other
fundamental enlightening that
are passed from a working
system (OS). Most other forms
are subordinate on the
operations of a processor.

7. • Utilized to handle pictures
so they can be shown on
your screen. A great video
card can make a huge
contrast within the quality
of your graphics, so this can
be especially imperative on
the off chance that you play
diversions or work with
photography and video.

•A bit may be a binary digit, the littlest increase of
information on a computer. A bit can hold as it were
one of two values: or 1, comparing to the electrical
values of off or on, respectively. Because bits are so
little, you seldom work with data one bit at a time. Bits
are usually assembled into a bunch of eight to make a
byte. A byte contains sufficient data to store a single
ASCII character, like "c".

•A kilobyte (KB) is 1,024 bytes. Computer capacity and
memory is regularly measured in megabytes (MB) and
gigabytes (GB). A medium-sized novel contains
approximately 1 MB of data. 1 MB is 1,024 kilobytes, or
1,048,576 (1024x1024) bytes, not one million bytes.
•Computer storage and memory is often measured in
megabytes (MB) and gigabytes (GB). A medium-sized
novel contains about 1 MB of information. 1 MB is
1,024 kilobytes, or 1,048,576 (1024x1024) bytes, not
one million bytes.

• Numerous hard drive manufacturers utilize a decimal number
system to characterize sums of storage space. As a result, 1 MB is
characterized as one million bytes, 1 GB is characterized as one
billion bytes, and so on. Since your computer employments a
twofold system as specified over, you'll take note a error
between your hard drive's distributed capacity and the capacity
recognized by your computer. For example, a difficult drive that's
said to contain 10 GB of capacity space employing a decimal
system is really able of putting away 10,000,000,000 bytes. Be
that as it may, in a binary system, 10 GB is 10,737,418,240 bytes.
As a result, rather than recognizing 10 GB, your computer will
recognize 9.31 GB. This is often not a glitch but a matter of
diverse definitions.

•Note: The names and abbreviate form numbers of
bytes are successfully mixed up with the
authentications for bits. The abbreviate form
numbers of bits make use of a small letter "b"
rather than a big letter "B". As 1 (one) byte is
made up of 8 (eight) bits. Bits and bit rates (as in
bits per second [bps]) are most commonly utilized
to illustrate connection speeds.

•No report has determine our lives, our culture and
our survival more than power. Power is
everywhere; it lights our way or cooks our food.
For an illustration, envision where the medical
field would be without power and in that sense
how numerous lives have been spared due to
electrical gadgets like oxygen, pacemakers, etc.
BACKGROUND
29. What is electricity and where does it
from? More desperately, why is carpet,
socks and a doorknob a awful
combination? In its least complex
terms, electricity is the development of
charge, which is considered by tradition
to be, from positive to negative. No
matter how the charge is made,
chemically (e.g. in batteries) or
physically (contact from socks and
carpet), the development of the
release is electricity.

WHAT IS ELECTRICITY?
30. This stream of electrical charge is
referred to as electric current.
There are two sorts of current,
coordinate current (DC) and
rotating current (AC). DC is
current that streams in one
direction with a steady voltage
extremity whereas AC is current
that changes course
intermittently together with its
voltage extremity.

WHAT IS CURRENT?
31. • Thomas Edison and
Alessandro Volta were
pioneers in DC current and
composed much of
electricity’s history. But as
social orders developed the
utilize of DC over long
transmission separations
got to be as well wasteful.
31
32. • Nikola Tesla changed all that
with the innovation of
substituting current
electrical frameworks. With
AC it is conceivable to
deliver the tall voltages
required for long
transmissions. In this
manner nowadays, most
convenient gadgets utilize
DC control whereas control
plants deliver AC.

• Ohm’s law expresses that, for a constant current, the
current in a circuit is specifically corresponding to the
overall voltage acting within the circuit and contrarily
relative to the overall resistance of the circuit.
• The law may be communicated by the taking after
condition in the event that the current I is in amperes,
EMF E is in volts, and the resistance R is in ohms.
• The relationship of the previous three factors was found
by Georg Simon Ohm, who theorized that current is in
coordinate extent to resistance.
