Chapter 27-Client server and peer-to-peer || 100% Certified
Answers.
client server network correct answers consists of one or more computers known as clients
connected to a powerful central computer known as the server
server correct answers is the central computer that communicates with other client nodes.
client correct answers any computer hardware or software device that requests access to a service
provided by a server.
what is the role of the server in the client server network correct answers the server manages the
network, and the clients are dependent on the server as it holds the important information and
resources and has a greater processing power than the clients.
what is the role of the clients in the client server model correct answers each client may hold
some of its own files and resources such as
software, and can also access resources held by the server. clients can make requests to the
servers which are then processed
types of servers correct answers file, print, web, mail, database
file server correct answers holds and manages data for all the clients
print server correct answers manages print requests
web server correct answers manages requests to access the web
mail server correct answers manages email system
database server correct answers manages database applications
advantages of client server model correct answers secure: since all files are stored in a central
location and access rights are managed by
the server. backups are done centrally so there is no need for individual users to back up their
data. If there is a
breakdown and some data is lost, recovery procedures will enable it to be restored
data and other resources can be shared
disadvantages of client server model correct answers expensive to set up. the functionality of
terminals depends on the server; if this fails, performance falls. trained staff are required to
maintain the server
application of the client server model correct answers email, the World Wide Web, and network
printing, game hosting
, cloud computing correct answers service-based industry that provides access to software or files
via the internet using the client-server model
cloud computing examples correct answers file storage facilities where users files are kept on
remote servers (onedrive), software via the cloud (software as a service), cloud based office
applications, accounting packages
peer to peer network correct answers individual computers are connected to each other,
either locally or over a wide area network so that they can share files. there is no central
computer
what is the role of clients in the peer to peer network correct answers each device effectively acts
as both a server and client, as it can both provide and request resources
advantages of peer to peer network correct answers cheaper to set up. allows users to share
resources easy to maintain. not dependent on a central server. specialist staff are not required
disadvantage of peer to peer network correct answers impossible to trace the origin of files.
backups must be performed separately. poorer security. may be difficult to locate resources
application of peer to peer correct answers home or small office, video on demand companies,
piracy
why are peer to peer networks used for video on demand correct answers hundreds of computers
can be used to hold parts of the video and
so share the load. this allows numerous of users to simultaneously download the same video
why are peer to peer networks used for piracy correct answers it is impossible to trace theoriginss
of the files
which are being illegally downloaded.
what are the effects of piracy correct answers moviemakers have fewer resources to invest in
new films, which causes a loss of jobs (in the music, movie, publishing and photography
industry)
how can data be processed in a client server model correct answers data may be processed by the
client, server or both
how do web servers work correct answers the http client sends a request to the http server and the
page data is sent back from the http server by way of response and the browser renders the web
page on the client's computer
what requests does the http client browser send correct answers client browser sends an HTTP
request to a web server for dynamic web
page data or a web resource, or when using a web page with an online search facility such as
checking
