It is generally accepted that in traditional text printing, the lining has a better readability (compared to sans-serif), especially in large passages, where the line increases the visual reference to the letter when reading. Sans serif are often used in headings, shorter text passages, or some entertainment. Compared to serious lines, no liner gives a relaxed feeling of

Prim Algorithm
1. Overview
Primm algorithm (prim algorithm), an algorithm in graph theory, can search for the smallest spanning tree in weighted connected graphs. This means that the subset of edges searched by this algorithm includes not only all the vertices in the connected graph (English: Vertex (graph theory)), but also the sum of the weights of all the edges is minimal. The algorithm was discovered in 1930

Compared with today's most advanced networks, the next generation of Ethernet data transmission speed 1000 times times faster, and more efficient. The researchers hope to develop a 1 Gigabit Ethernet (1000G per second transmission) in 2015 and transmit data through fiber optics, with the ultimate go
