Module 2: Network components, types and connections Flashcards
What type of network is defined by two computers that can both send and receive requests for resources?
The simplest form of peer-to-peer networking consists of two computers that are directly connected to each other through the use of a wired or wireless connection.
What are two functions of end devices on a network?
End devices originate the data that flows through the network. They are the interface between humans and the communication network. Intermediary devices direct data over alternate paths in the event of link failures and filter the flow of data to enhance security. Network media provide the channel through which network messages travel.
A home user is looking for an ISP connection that provides high speed digital transmission over regular phone lines. What ISP connection type should be used?
DSL is the best technology to use over existing phone lines. A lot of ISPs have a lookup on their website where you can enter your phone number and see if they can offer you service.
What type of internet connection would be best for a residence in a remote area without mobile phone coverage or wired connectivity?
Satellite internet service provides the best option for a home user that would otherwise have no internet connectivity at all. Cellular internet is only available in areas with mobile phone coverage.
Which term correctly describes the function of an ISP?
ISP stands for internet Service Provider. An ISP is responsible for providing the link between a private network, such as a home or business network, and the internet.
Which devices are an intermediary device?
An intermediary device sends network messages toward a final destination. Examples of intermediary devices include a firewall, router, switch, multilayer switch, and wireless router.
Which scenario describes a peer-to-peer network?
In a peer-to-peer network there is no centralized or dedicated server. A user computer can be a client to request service from another user computer and a server to share a network resource (such as a printer) to other users.
Which term is used to describe a network device with the primary function of providing information to other devices?
Servers are devices with software installed that allows them to provide information, like web pages or email.
What is an advantage of the peer-to-peer network model?
The simplest peer-to-peer network consists of two computers that are directly connected to each other through the use of a wired or wireless connection. The advantages of peer-to-peer networking include ease of setup, lower cost, and less complexity.
What is a characteristic of a peer-to-peer application?
Peer-to-peer networks exist directly between client devices, with no centralized resources or authentication. Hybrid peer-to-peer systems also exist that decentralize resource sharing but can use centralized indexes to point to the resource locations.
