is that torus is (topology) a topological space which is a product of two circles while ring is a circumscribing object, (roughly) circular and hollow, looking like an annual ring, earring, finger ring etc or ring can be the resonant sound of a bell, or a sound resembling it or ring can be (algebra) an algebraic ...

A toric lens is a lens with different optical power and focal length in two orientations perpendicular to each other. One of the lens surfaces is shaped like a "cap" from a torus (see figure at right), and the other one is usually spherical.

FDDI uses a dual ring topology. The dual ring topology uses two counter-rotating rings known as the primary and secondary ring. The primary ring is similar to the main ring path in token-ring terminology.

Difference Between Circle and Sphere. A circle is a closed curved line. Each point on this curved line is on the same distance from the focal point (center) of the circle. ... In simple terms – a circle is a round object in a plane, while a sphere is a round object in a space.

As nouns the difference between mesh and grid is that mesh is a structure made of connected strands of metal, fiber, or other flexible/ductile material, with evenly spaced openings between them while grid is a rectangular array of squares or rectangles of equal size, such as in a crossword puzzle.

A ring system around a planet is also known as a planetary ring system. The most prominent and most famous planetary rings in the Solar System are those around Saturn, but the other three giant planets (Jupiter, Uranus, and Neptune) also have ring systems.

They are typically used on higher quality office binders, and preferred for larger projects because they hold about 30% more sheets of paper, and are more durable than round rings. D-Ring Binders have rings shaped like an inverted "D", and are better quality than round ring.

In mesh topology, the nodes are connected to each other completely via dedicated link. ... In ring topology, the information is travel from nodes to nodes in ring manner in one direction. In mesh topology, the information is travel from nodes to nodes.

Differences: Ring vs Ring Pro First off, while the traditional Ring doorbell is wireless, the Ring Pro requires that it be wired into an existing (or new) wiring system. Another difference is in the camera itself.

The main difference between the two is the size. Nano rings are around 90% smaller in size than micro rings, and are about the same size as a ballpoint pen nib. Micro ring hair extensions should not be noticeable at all in your hair, if installed correctly. ... Both micro rings and nano rings are comfortable to wear.

A Field is a Ring whose non-zero elements form a commutative Group under multiplication. A Ring is an algebraic structure with two binary operations, and , that generalise the arithmetic operations of addition and multiplication. ... Multiplication is associative; and. Multiplication distributes over addition.

The crucial difference between bus and star topology is that bus topology uses a single cable through which various peripheral devices are connected. As against a star topology makes use of central hub or switch that broadcasts information to all the devices in the network.

['Surface Area. The surface area of a Torus is given by the formula – Surface Area = 4 × Pi^2 × R × r. Where r is the radius of the small circle and R is the radius of bigger circle and Pi is constant Pi=3.14159.', 'Volume. The volume of a cone is given by the formula – Volume = 2 × Pi^2 × R × r^2.']

A hex bolt relies on a 60 degree angle while the Torx bit relies on a 15 degree angle. The significantly smaller drive angle forms a much tighter tolerance, which better distributes the concentration of force to all points and therefore allows for much higher torque values before rounding out.

Toric contact lenses can rectify astigmatism. The main difference between these and regular lenses is the design. Regular lenses have just one power, but toric lenses have two: one for distance vision and one for astigmatism. ... Toric lens fittings are usually longer than regular lens fittings.
