DSYS - DISTRIBUTED SYSTEMS TEST QUESTIONS
AND ANSWERS
50 QUESTIONS AND ANSWERS
what is a distributed system - ANSWER I distributed system is one in which
two components located at Networked computers communicate and coordinate
access only by passing messages
concurrency - ANSWER in a network of computers, concurrent program
execution if the norm I can do my work on my computer while you do your
work on yours, sharing resources such as web pages or files when necessary.
No global clock - ANSWER when there are limits to the accuracy in which the
computers in a network can synchronize their clocks there is no Global notion
of the correct time
independent failure - ANSWER all computer systems can fail, and it is the
responsibility of system designers to plan for the consequences of possible
failures
web search - ANSWER the task of the web search engine is to index the entire
contents of the World Wide Web, encompassing a wide range of information
Styles including webpages multimedia sources and scanned books
multimedia online games - ANSWER utilizes client-server architecture in
which a single copy of the state of the world is maintained on a centralized
server and accessed by client programs running on players computers or other
devices
backbone - ANSWER a backbone is a network link with high a high
transmission capacity, employing satellite connections, fiber optic cables, and
other high-bandwidth circuits
mobile computing - ANSWER mobile Computing is the performance of
computer task while the user is on the move or visiting places other than their

collection of related resources and presents their functionality to users and
applications
what does that file service provide? - ANSWER read, write and delete
operations on files
server - ANSWER her running program in process on a network computer that
accepts requests from programs running on other computers to perform a
service and respond appropriately
what is a remote invocation - ANSWER a complete interaction between a
client and a server, from the point when the client sends its request to when it
receives the service response
middleware - ANSWER and software that provides a programming abstraction
as well as masking the heterogeneity of underlined networks, Hardware,
operating systems and other programming languages
physical model - ANSWER a representation of the underlined Hardware
elements cover distributed system that abstract away from specific details of the
computer and networking Technologies employed.
internet scale distributed systems - ANSWER incorporation of large number of
nodes and provide distributed system services for Global organizations in across
organizational boundaries
