Evolution of Ethernet from a Coaxial Cable Bus to Hub Managed, Twisted Pair Network
The first step in the evolution of Ethernet from a coaxial cable bus to a hub managed, twisted pair network was the introduction of the Star LAN. Here is a detailed explanation of this evolution:
1. Coaxial Cable Bus:
- Initially, Ethernet networks were based on a coaxial cable bus topology.
- In this setup, all devices were connected to a single cable, forming a bus-like structure.
- Data was transmitted over the cable, and each device could listen to the data being transmitted.
2. Limitations of Coaxial Cable Bus:
- The coaxial cable bus had limitations in terms of distance, speed, and scalability.
- It had a limited maximum distance for data transmission.
- As the network grew, the signal quality degraded, leading to performance issues.
- The bus topology was also susceptible to collisions, resulting in data collisions and network congestion.
3. Introduction of Star LAN:
- To overcome the limitations of the coaxial cable bus, the Star LAN topology was introduced.
- In the Star LAN, each device is connected to a central device called a hub or switch using twisted pair cables.
- The hub or switch acts as a central point for data transmission and management.
4. Advantages of Star LAN:
- The Star LAN topology addressed the limitations of the coaxial cable bus.
- It allowed for longer cable distances, as the hub or switch could regenerate and amplify the signal.
- Each device had its own dedicated connection to the hub or switch, eliminating the signal degradation issues of the bus topology.
- The star topology also reduced the likelihood of collisions, improving network performance and reliability.
5. Further Evolution:
- After the introduction of the Star LAN, Ethernet continued to evolve.
- Ring LAN and Mesh LAN are other network topologies that were developed, but they did not directly lead to the hub managed, twisted pair network evolution.
- Ring LAN uses a ring topology, and Mesh LAN employs multiple direct connections between devices.
In conclusion, the first step in the evolution of Ethernet from a coaxial cable bus to a hub managed, twisted pair network was the introduction of the Star LAN topology. This topology addressed the limitations of the coaxial cable bus and provided improved performance, scalability, and reliability for Ethernet networks.

Key Points 

• The curricular and pedagogical structure and the curricular framework for school education will therefore be guided by a 5 + 3 + 3 + 4 design, consisting of the stages:
  • Foundational (3 years of preschool + Grades 1-2):- The Foundational Stage will consist of play/activity-based learning. It will also include a focus on good behavior, courtesy, ethics, personal and public hygiene/cleanliness, teamwork, cooperation, etc. 
  • Preparatory (Grades 3- 5):-  The Preparatory Stage will transition gradually from play-based learning to more formal but interactive classroom learning, with the introduction of some (light) textbooks, in order to lay a solid groundwork across subjects, including reading, writing, speaking, physical education, art, languages, science, and mathematics.
  • Middle (Grades 6-8):- The Middle Stage will see the introduction of subject teachers for learning/discussion of the more abstract concepts in each subject that students will be ready for at this stage, across the sciences, mathematics, arts, social sciences, and humanities.
  • High school (Grades 9-12 in two phases, i.e. 9 and 10 in the first and 11 and 12 in the second) stages respectively, with an option of exiting at Class 10 and re-entering in the next phase:- The High School (or Secondary) Stage will comprise of four years of multidisciplinary study, building on the subject-oriented pedagogical and curricular style of the Middle Stage, but with greater depth, greater critical thinking, greater attention to life aspirations, and greater flexibility and student choice.

Thus, it is concluded that Primary classes (Classes I to V) will consist of  Preparatory and  Foundational Stages according to NEP, 2020.

Preference to one sex over the other is called gender bias. Here the school prefers girls for the competition, thereby reflecting gender bias.

School principal fulfils many roles and dealing with students' disruptive behaviour is among the least preferred by them. So, the teacher must try to discipline the students using various means like assigning responsibility to the undisciplined, finding out the underlying cause of his behaviour, and so on. Only after she has done everything without any effect on the student should she send the student to the principal.

Assessment is integral to the teaching-learning process which helps in facilitating student learning and improving instruction.

• Formative assessment is goal-centered that is, it focuses attention on successful teaching and learning of important learning goals and standards.
• It identifies the learning gaps and deficiencies in teaching.
• In this form of assessment, a teacher embeds various forms of assessment all through the teaching and learning process. 
• Therefore, it is an ongoing assessment that allows teachers to monitor students on a day-to-day basis and modify their teaching based on what the students need to be successful.

For example, during a teaching in a class teacher ask questions, the teacher says to discuss among peer groups, observe children as they work on their tasks, a teacher receives feedback from students during teaching etc.

This task is known as paragraph dictation.

Critical thinking is a process that challenges an individual to use reflective, reasonable, rational thinking to gather, interpret, and evaluate information in order to derive a judgment.

The NRF (National Research Foundation) will be governed, independently of the government, by a rotating Board of Governors consisting of the very best researchers and innovators across fields.

Key Points

•  The goal of the NRF will be to enable a culture of research to permeate through our universities.
• The primary activities of the NRF will be to:
  •  fund competitive, peer-reviewed grant proposals of all types and across all disciplines.
  •  seed, grow and facilitate research at academic institutions.
  • act as a liaison between researchers and relevant branches of government as well as industry; so as to allow breakthroughs to be optimally brought into policy and/or implementation.
  • recognize outstanding research and progress.

Thus, it is concluded that According to NEP‐2020, National Research Foundation (NRF) may be established to enable a culture of research to permeate through universities.

In junior section, Mrs Singh is teaching about Earth, its shape and rotation by using a globe. In such teaching, learning take place by observation. Students observe the globe to get knowledge.

Observational learning is the learning that occurs through observation of the behavior of others. It is a form of social learning which takes various forms, based on various processes.

A picture will be the best teaching aid to teach the subject of biology. A number of pictures can be used to teach each of the processes individually.

The electrons in a conductor have random velocities and when an electric field is applied, they suffer repeated collisions and in the process move with a small average velocity, opposite to the direction of the field. This is equivalent to positive charge flowing in the direction of the field.

Radius of electron orbit
r = 0.72Å = 0.72 × 10⁻¹⁰m
Frequency of revolution of electron in orbit of given atom
v = 9.4 × 10¹⁸ rev/s
(where T is time period of revolution of electron in orbit)
∴ Then equivalent current is
I = e/T = ev = 1.6 × 10⁻¹⁹ × 9.4 × 10¹⁸
= 1.504A

A body at temperature T produces a continuous spectrum of wavelengths. For a black body, the wavelength corresponding to maximum intensity of radiation is given according to Planck's law by the relation, m=0.29cmK/T. For m=106m,T=2900K.Temperatures for other wavelengths can be found. These numbers tell us the temperature ranges required for obtaining radiations in different parts of the electromagnetic spectrum. Thus, to obtain visible radiation, say  =5×107m, the source should have a temperature of about 6000K. A lower temperature will also produce this wavelength but not the maximum intensity.

Power of lens, P (in dioptre) = 100/f(in cm)
∴  f  = 100/10 = 10 cm
For biconvex lens, R₁ = + R, R₂ = -R =  According to lens makers formula

Current flows in a conductor due to the flow of negatively charged electrons. However, the direction of conventional current is taken to be opposite to the direction of flow of electrons. It can therefore be considered as the direction in which positive charges move.

Let atomic weight of x = Mx

atomic weight of y = M_y

we know,

mole = weight /atomic weight

a/c to question,

mole of xy₂ = 0.1

so,

0.1 = 10g/( M_x +2M_y)

M_x + 2M_y = 100g -------(1)

for x₃y₂ ; mole of x₃y₂ = 0.05

0.05 = 9/( 3M_x + 2M_y )

3M_x + 2M_y = 9/0.05 = 9× 20 = 180 g ---(2)

solve eqns (1) and (2)

2M_x = 80

M_x = 40g/mol

and M_y = 30g/mole

Mendeleev arranged all 63 elements; which were discovered till his time; in the order of their increasing relative atomic masses in a tabular form. It is known as Mendeleev's Periodic Table. He divided the table in eight columns and seven rows. The columns are known as groups and rows are known as periods.

Since the reagent is BaCl₂(aq), displacement reaction will take place. The resulting solution, if insoluble in water, will form a white precipitate. Both BaNO₂ and BaCl₂ are soluble in water and hence will not form a precipitate. BaSO₄, however, is insoluble in water and hence forms a white precipitate.
