1. What is bandwidth? What do you think affects the differences in bandwidth globally as well as in different locations in the U.S.?
Bandwidth refers to the amount of data that can be sent in a fixed amount of time and is usually measured in kilobits or megabits per second. Bandwidth speeds vary across the globe, with the current global average being 18.4 Mbps download. Korea leads the world with 52.6 Mbps, while in the US the average is 24.4 Mbps. I think there are many factors affecting the differences in bandwidth globally and domestically, such as the number of different Internet tasks running, the number of users on a single connection, and the wireless protocols that routers run under.
2. What is latency? How does it differ from bandwidth? Why is it a useful measure?
Latency refers to how long it takes a packet of data to go from its source (e.g., a client) to its destination (e.g., a server). In combination, latency and bandwidth define the speed and capacity of a network. Latency is the speed, while bandwidth is the capacity.
3. What is the digital divide? What are some ways to reduce the effects of the digital divide?
The digital divide is the difference between those who have access to the Internet and those who do not. Solutions to reduce the effects of this divide include increased awareness of the benefits of Internet use globally and to make Internet connection affordable for more people.
