181) Asteroids have their orbits between the planets ________
(A) Mercury and Venus
(B) Earth and Mars
(C) Mars and Jupiter
(D) Jupiter and Saturn
Correct Answer - Option
(C)
Explanation :
Asteroids are primarily found in the Asteroid Belt, which is located between the orbits of Mars and Jupiter. This region contains numerous rocky bodies that never formed into a planet due to Jupiter's strong gravitational influence.
(A) Mercury and Venus → No significant asteroid belt exists here.
(B) Earth and Mars → Some asteroids (like near-Earth asteroids) exist, but not a major belt.
(D) Jupiter and Saturn → This region has Trojan asteroids, but the main asteroid belt is between Mars and Jupiter.
185) Which of the following is the largest of the inner planets?
(A) Venus
(B) Mercury
(C) Mars
(D) Earth
Correct Answer - Option
(D)
Explanation :
The inner planets (also called terrestrial planets) are Mercury, Venus, Earth, and Mars. Among them, Earth is the largest in terms of both diameter and mass.
186) Which of the following scientist had proven that every planet has an elongated path?
(A) Galileo
(B) Newton
(C) Copernicus
(D) Kepler
Correct Answer - Option
(D)
Explanation :
Johannes Kepler formulated the Laws of Planetary Motion, which describe how planets move around the Sun. His first law, known as the Law of Ellipses, states that:
"The orbit of every planet is an ellipse with the Sun at one of the two foci."
Galileo (A) contributed to observational astronomy but did not define planetary orbits.
Newton (B) formulated the laws of motion and universal gravitation but did not discover elliptical orbits.
Copernicus (C) proposed the heliocentric model but believed planetary orbits were circular.
188) A network that requires human intervention to route signals is called
(A) Star network
(B) Ring network
(C) Bus network
(D) T-switched network
Correct Answer - Option
(D)
Explanation :
The correct answer is:
(D) T-switched network
Explanation:
A T-switched network (Telephone-switched network) requires human intervention or a mechanical switchboard to route signals. These networks were commonly used in traditional telephone systems, where operators manually connected calls.
Star network (A): A network topology where all devices connect to a central hub, but routing is automatic.
Ring network (B): A network where each node connects to two others in a loop, and signals pass automatically.
Bus network (C): A network where all devices share a single communication line, and signals travel automatically.
189) Connection or link to other documents or web pages that contain related information is called
(A) Domain name
(B) Hyperlink
(C) Electronic commerce

190) What is the basic unit within a computer that capable of holding a single unit of data?
(A) Register
(B) ALU
(C) Control unit
(D) Store location
Correct Answer - Option
(D)
Explanation :
A register is the smallest and fastest storage unit in a computer that holds a single unit of data (usually a word or a byte). Registers are located inside the CPU and are used for temporary storage during processing.
ALU (B) (Arithmetic Logic Unit) performs calculations and logical operations but does not store data permanently.
Control Unit (C) directs operations within the CPU but does not store data.
Store Location (D) is a vague term; memory locations store data, but registers are the most basic unit.
