Hi! I'm a ISP/ Car salesman. Here we have 3 different services for your internet surfing needs. DSL, which is reliably constant but slower. Cable, which is not as constant, but faster and Fiber Optics, which is not as accessible but the fastest available.
(DSL)Slower (Cable)Faster (Fiber Optic)Fastest
The different ISP's vary between speeds, but also cost. Typically, the faster the typeof internet, the more it costs.
So make sure to choose the right performance for the the right cost for your enjoyment!
