(b) Explain Client-Server architecture and Peer-to-Peer Architecture.​

Answer 1

Answer:

The numerous types of impairment that impact computer usage are :- * Cognitive impairments and learning disabilities, such as dyslexia, attention deficit-hyperactivity disorder (ADHD) or autism. * Visual impairment such as low-vision, complete or partial blindness, and color blindness

The main difference between client-server and peer to peer systems is that in the client-server architecture, there are designated clients that request for services and servers that provide services, but in peer to peer systems, peers act as both service providers and service consumers.
