Describe dial-up Internet service and an alternate to dial-up access for Internet service.
What will be an ideal response?
Dial-up Internet service uses a voiceband modem and telephone lines to transport data between your computer and your ISP. Many ISPs-including AT&T, AOL, and EarthLink-offer dial-up Internet access. The service typically costs less than US$10 per month, but access speed is slow. Dial-up connections are not suitable for playing online games, teleconferencing, or watching videos. Even downloading software and essential operating system updates can take hours.
Satellite Internet services distribute broadband asymmetric Internet access by broadcasting signals to and from a personal satellite dish. In many rural areas, satellite Internet service is the only alternative to dial-up access. Unfortunately, susceptibility to bad weather makes it less reliable than cable-based services. In addition, the time required for a signal to travel to a satellite-called latency-makes this type of connection too slow for online gaming.
