Nowadays, common servers are generally divided into tower servers, rack servers and blade servers, and commonly used Web servers are front-end servers. Of the two, although the tower server takes up a larger space, it is cheaper than the rack server and has the same design as an ordinary PC chassis. Some manufacturers do not even need to equip a special computer room and can just put it in the office. With the development of IT technology, today's tower servers have less noise, better heat dissipation, and very good processing performance, so many small and medium-sized enterprises choose tower servers as web servers. Rack-mounted servers are chosen by enterprises because of their standard design, impressive expansion capabilities, powerful processing performance and stability. They are placed in standard server cabinets, which are both convenient and beautiful.
