Question Discussion & Solution

the correct answer is MS-DOS.

MS-DOS is not a GUI-based operating system

Key Points

• MS-DOS is a text-based operating system, meaning that a user works with a keyboard to input data and receives output in plain text. Later, MS-DOS often had programs using a mouse and graphics to make work more simple and quick.
• MS-DOS is a non-graphical command line operating system derived from 86-DOS that was created for IBM-compatible computers.
• MS-DOS allows the user to navigate, open, and otherwise manipulate files on their computer from a command line instead of a GUI like Windows.

Important Points

• Some popular, modern graphical user interface examples include:
  • Microsoft Windows,
  • macOS, Ubuntu Unity,
  • GNOME Shell for desktop environments, and
  • Android,
  • Apple's iOS,
  • BlackBerry OS,
  • Windows 10 Mobile,
  • Palm OS-WebOS, and
  • Firefox OS for smartphones.

​Additional Information 

• Graphical User Interface (GUI) 
  • The graphical user interface is used by the most commercially popular computer operating systems 
  • A Graphical User Interface (GUI) allows you to enter commands by pointing and clicking at objects that appear on the screen.
  • It consists of picture-like items (icons and arrows for example).
  • In most operating systems, the primary user interface is graphical.

The correct answer is Kuchipudi Dance.

• Yamini Krishnamurti is related to Kuchipudi Dance.

Key Points 

• Yamini Krishnamurti is a Kuchipudi dancer.
• She also knows Bharatnatyam.
• A Passion For Dance is her autobiography.
• Kuchipudi:
  • It is the classical dance of Andhra Pradesh.
  • Kuchipudi derives its name from the Kuchipudi village of Andhra Pradesh.
  • Kuchipudi exhibits scenes from the Hindu Epics, legends and mythological tales through a combination of music, dance and acting.
  • Like other classical dances, Kuchipudi also comprises pure dance, mime and histrionics but it is the use of speech that distinguishes Kuchipudi’s presentation as dance-drama.
  • ‘At times, even though the dramatic situation did not demand, solo dancing was being presented to punctuate the presentation and to enhance the appeal. One such number is tarangam inspired by the Krishna-Leela tarangini of Teerthanarayana Yogi.
  • There are now two forms of Kuchipudi
    • The traditional musical dance drama 
    • The solo dance.
• Bharatnatyam is the classical dance of Tamil Nadu.

The pattern followed here is:

Hence, ‘JGW’ complete the series.

CONCEPT:

Electric Charge: It is a physical property of a matter that experiences a force when placed in an electromagnetic field.

• Electric charges create electric fields.

• Two types of charges are found – 1.) Positive charge. 2.) Negative charge
• Force experienced when charge placed in the electromagnetic field is \({{F}^{\to }}=q\times {{E}^{\to }}\) where q = charge of the body (in coulomb). \({{E}^{\to }}\) = intensity of the electric field.
• SI unit of charge is Coulomb and the symbol is C. One coulomb is equal to the charge on 6.241 x 10¹⁸ protons.

Inductor: It is a passive electric component that stores energy in the form of magnetic field lines. It is a simple loop of wire.

• The inductance of the inductor could be measured by equation L = Φ / I where ϕ is magnetic flux and I is a current flowing through it.
• SI unit of inductance is Henry.
• Energy stored in Inductor U = ½ (LI²).

Capacitor: It is a device consisting of two conducting "plates" separated by an insulating material (dielectric). It stores energy in the form of an electric field with the help of an electric charge.

• The capacitance of a capacitor is measured by equation C = q /Δ v where q is charge and ∆ V is a potential difference.
• SI Unit of capacitance is Farad.
• Energy stored in Capacitor U = ½ (CV²)

Resistance: It is a measure of how the device reduces the flow of electric current, basically it opposes the flow of charges.

• Further, it states the ratio of the applied voltage to electric current flows through it.
• R = V/I [R is resistance, V is the potential difference and I is electric current].
• Also, R = ρ × (L/A) [where ρ is specific resistance of the material, l is the length of conductor and A is the cross-sectional area of the conductor].
• The unit of resistance is volt/ampere or ohm (Ω).
• It does not store energy.

Transformer: It is an electrical device that converts A/C current from one voltage to another.

EXPLANATION:

• A capacitor stores energy in the form of electrical charges and fields.
• Here, C_o = Capacitance, V = voltage, A = area of the plates, d = distance between them.

\(\Rightarrow {{C}_{o}}=\frac{{{Q}_{o}}}{V}=\frac{{{\epsilon }_{o}}A}{d}\)

Important Points

• Remember Electric field lines are stored in capacitor & magnetic field lines are stored in Inductor.

Information systems hardware is the part of an information system one can touch i.e. the physical components of the technology.

Computers, keyboards, disk drives, iPads, and flash drives are all examples of information systems hardware.
