Peer to peer networking is different from other types because there is no server within the network. The devices within the network communicate without any centralized control . The devices are equivalently responsible data processing. Peer to peer networks are characterized by; Scalable and Secure Peer Name Resolution Efficient Multipoint Communication Distributed Data Management Secure Peer Identities Secure Peer-to-Peer Groups The difference between peer to peer networks and client-server networks is based on the design architecture.In client-server networks, it’s designed that the clients request for services while the server provides the services but in the peer to peer architectur

When the providers allow virtualization by multiplexing many customers’ Virtual Machines (VM) across the same physical infrastructure, it leads to security related vulnerabilities for the customers. The vulnerabilities could arise because it is possible to map the internal cloud infrastructure, then instantiate new VMs, so one could be placed as a co-resident with the target, and then finally such placement could be used to initiate cross-VM side-channel attacks to steal or extract information from a target VM on the same physical machine or infrastructure.
4). Broadband “refers to ‘always on’ access to data (including the internet) at a speed or bandwidth, greater than dial-up modems” (Downing 2011, p. 4).
