What Is Difference Between
( Everyday Science )
Difference between Star and Planet
Star
i) Stars are self-luminous heavenly bodies.
ii) They do not revolve around the sun.
iii) They are usually stationary.
iv) Examples: fixed stars, binary stars.
Planet:
i) Planets are rocky non-luminous bodies.
ii) They revolve round the sun.
iii) They usually move.
iv) Examples: Mercury, Venus, Jupiter etc.

Difference between BIT and BYTE
A bit is defined as: a single basic unit of information, used in
connection with computers and electronic communication. All modern computers
store and use data in digital form. The smallest unit of storage and
measurement is one binary digit, therefore its name.
A byte, pronounced ‘bite’, is the next size up basic unit of measurement for information storage, usually consisting of eight bits. These 8 bits are grouped together to form a byte that is, a total or 8 grouped bits representing one character of data.
Therefore, so far we have two basic units of measuring digital information storage that have different capacities, they are:
• 1 Bit
• 8 Bits equal 1 Byte

Difference between Fission and Fusion
Fission:
i) Lighter atoms are fused together at a very high temperature to form heavier elements.
ii) It is difficult to carry out on the earth.
iii) It has no nuclear waste problem.
iv) It requires cheaper and abundant elements.
v) Not possible at concerning scale as high temperature is needed to start it.
Fusion:
i) Heavier unstable atoms are broken down to produce energy.
ii) It is easy to carry out on the earth.
iii) It has nuclear waste radioactivity disposal problem.
iv) It requires expensive and rare elements.
v) Possible to commercialize under controlled measure.

Difference between Telemeter and Multimeter
Telemeter:
A telemeter is a device used to remotely measure a quantity. Telemeters are generally the physical devices used in telemetry. Electronic devices are widely used in telemetry and can be wireless or hard-wired, analogue or digital. Other technologies are possible, however, such as mechanical, hydraulic and optical.
Multimeter:
A multimeter or a multi-tester, also known as a VOM (Volt-Ohm meter), is an electronic measuring instrument that combines several measurement functions in one unit. A typical multimeter may include features such as the ability to measure voltage, current and resistance. Multimeters may use analogue or digital circuits—analogue multimeters (AMM) and digital multimeters (often abbreviated DMM or DVOM.) Analog instruments are usually based on a micro-ammeter whose pointer moves over a scale calibrated for all the different measurements that can be made; digital instruments usually display digits, but may display a bar of a length proportional to the quantity being measured.
A multimeter can be a hand-held device useful for basic fault finding and field service work or a bench instrument which can measure to a very high degree of accuracy. They can be used to troubleshoot electrical problems in a wide array of industrial and household devices such as electronic equipment, motor controls, domestic appliances, power supplies, and wiring systems.
