3. Describe the dif- o In client-server, the architecture defines two distinct roles:
ference between (1) Servers' role is to serve clients' requests. To do so, the server location
peer-to-peer and needs to be known, the server needs to be always active, and the server
client-server architec- needs to have suflcient resources (memory, communication capacity,
ture. computing power, etc).
(2) The clients emit requests at random times and do not need to have
fixed location, have large amount of resources or be always active.
- In peer-to-peer, devices act both as clients and servers. (optional) The key
advantage is that not only demand/requests, but also the overall system's
resources grow with the number of active devices.
