What is a Router? How do Routers work? 

The soonest chronicled record of a pen with a supply goes back to the tenth century AD. In 953, Ma'ād al-Mu'izz, the Fatimid Caliph of Egypt, requested a pen which would not recolor his hands or garments, and was furnished with a pen which held ink in a repository and conveyed it to the nib.[15] This pen may have been a wellspring pen, yet its system stays obscure, and just a single record making reference to it has been found. A later store pen was created in 1636. In his Deliciae Physico-Mathematicae (1636), German designer Daniel Schwenter portrayed a pen produced using two plumes. One plume filled in as a supply for ink inside the other plume. The ink was fixed inside the plume with plug. Ink was crushed through a little opening to the composition point. In 1809, Bartholomew Folsch got a patent in England for a pen with an ink reservoir.[15] 

While an understudy in Paris, Romanian Petrache Poenaru created the wellspring pen, which the French Government protected in May 1827. Wellspring pen licenses and creation at that point expanded in the 1850s. 

The primary patent on a ballpoint pen was issued on October 30, 1888, to John J Loud.[16] In 1938, László Bíró, a Hungarian daily paper proofreader, with the assistance of his sibling George, a scientist, started to outline new sorts of pens, incorporating one with a minor ball in its tip that was allowed to turn in an attachment. As the pen moved along the paper, the ball turned, grabbing ink from the ink cartridge and abandoning it on the paper. Bíró documented a British patent on June 15, 1938. In 1940 the Bíró siblings and a companion, Juan Jorge Meyne, moved to Argentina escaping Nazi Germany. On June 10 they recorded another patent, and shaped "Bíró Pens of Argentina". By the mid year of 1943 the principal business models were available.[17] Erasable ballpoint pens were presented by Papermate in 1979 when the Erasermate was put available.

Slavoljub Eduard Penkala, a naturalized Croatian specialist and designer of Polish-Dutch source from the Kingdom of Croatia-Slavonia in Austria-Hungary, ended up prestigious for further advancement of the mechanical pencil (1906) – at that point called a "programmed pencil" – and the main strong ink wellspring pen (1907). Teaming up with a business visionary by the name of Edmund Moster, he began the Penkala-Moster Company and manufactured a pen-and-pencil industrial facility that was one of the greatest on the planet at the time. This organization, now called TOZ-Penkala, still exists today. "TOZ" remains for "Tvornica olovaka Zagreb", signifying "Zagreb Pencil Factory". 

Current marker pens 

In the 1960s, the fiber or felt-tipped pen was concocted by Yukio Horie of the Tokyo Stationery Company, Japan.[18] Paper Mate's Flair was among the primary felt-tip pens to hit the U.S. advertise in the 1960s, and it has been the pioneer from that point forward. Marker pens and highlighters, both like felt pens, have turned out to be mainstream as of late. 

Rollerball pens were presented in the mid 1970s. They utilize a versatile ball and fluid ink to deliver a smoother line. Mechanical advances amid the late 1980s and mid 1990s have enhanced the roller ball's general execution. A permeable point pen contains a point made of some permeable material, for example, felt or artistic. A great drafting pen will ordinarily have a fired tip, since this wears well and does not widen when weight is connected while composing. 

Despite the fact that the innovation of the  and PC with the console input strategy has offered another approach to compose, the pen is as yet the principle methods for writing.[19] Many individuals jump at the chance to utilize costly composes and brands of pens, including wellspring pens, and these are here and there viewed as a materialistic trifle.
