Pushing processing to the client makes sense when local input needs to be processed (data validation), when client interfaces need to be updated more frequently than the server, when the client needs to regularly perform specialized tasks or use specialized views, and in other situations.
The client/server architecture that serves as the cornerstone of cooperative processing will be covered in this article. Demands on the sources' interoperational capacity, the growth of source sizes, and the growth of the client base are the three main determinants of the application of client/server architecture.
In addition to the fundamental variations in the architecture, the potential for multi-disk applications and cache memory on the customer side will also be taken into account.

write a function called orbit that takes three inputs and returns three outputs. our function is related to a planet that is in orbit around a star. remember that planets have elliptical orbits, like this:
Answer:
function [circT, ram1T, ram2T] = orbit(major, minor, velo)
a = major;
b = minor;
v = velo;
days = 86400;
% Circular approximation
circT = ((2 * pi *sqrt((a^2) + (b^2))/(2))/ v )/ days;
% Ramanujan's first approximation
ram1T = (pi * (3 * (a + b) - sqrt((3 * a + b) * (a + 3 * b)))/v)/days;
% Ramanujan's second approximation
h = ((a - b)^2) / ((a + b)^2)
ram2T = (pi * (a + b) * (1 + (3 * h )/ (10 + sqrt(4 - 3 * h)))/v)/days;
end
Explanation:
A planet is a celestial body that (a) orbits the sun and (b) has enough mass for its own gravity to outweigh the forces of rigid bodies and establish hydrostatic equilibrium.
The Sun (star) drags planets down into an orbit around it with its gravitational attraction. The elliptical course of their orbit is maintained by this gravity, which is a crucial force. As this force of gravity is directly proportional to mass and inversely proportional to the distance between them, if it changes, it will have an impact on the celestial bodies that revolve around it, such as planets. According to the query, when the star's gravity grows, planets will be more drawn towards the sun, reducing the distance between the star and the planet. As a result, the orbital path will get smaller, and the orbital period will increase.
