Review CS 4513

File Systems What is a partition? How do you get access? What is a file descriptor?

File Systems What is good about storing files as contiguous blocks? What is bad? Why is a file allocation table (FAT) better than a pure linked-list when storing disk blocks? What is an i-node?

File Systems What is an MBR/GPT for? Where are file attributes stored? What is an alias in terms of file systems? – How is a hard-link in a typical Unix file system implemented?

File Systems Describe one method of keeping track of free blocks in a file system What is the best block size to choose when formatting a partition with a file system? What are the performance tradeoffs in choosing the block size?

Sockets+ What does bind() do? – Who calls bind(), the client or server? How do you re-direct stdout to a socket?

HLM02 Compare and contrast WAFL i-nodes to traditional i-nodes. What is a snapshot? How is it implemented? – What is copy-on-write?

HML02 Performance methodology for NFS appliance? – Why not simply time to open() ? – Why not simply top throughput?

Distributed File Systems Compare and contrast stateful vs. stateless server for distributed file system How does NFS (v3) handle potentially out- dated client caches?

RG10 What are micro-benchmarks? – What are the micro-benchmarks used in RG10? What are macro-benchmarks? – What are the macro-benchmarks used in RG10?

RG10 How does the performance of FUSE compare to native? How does the performance of JavaFuse compare to FUSE and Native?

SKH02 What are the 3 fundamental limitations faced by MCGs?

SKH02 What is the tension/tradeoff between responsiveness and consistency in MCGs? What is interest management? Describe how it works What is dead reckoning? Describe how it works

CCL14 Label A-E in Figure What type of service is this? B C E D A

Cla09 Regarding thin-client games: – What is scene complexity? – What is motion? Where are First Person Shooters in that space?

Thin Client Games from [CFGS14] Order the following from least to most bitrate A.Virtual Environment B.Thin Game C.Pre-recorded video D.Live Video E.Traditional Game

Latency and Games from [CC10] What three ways does latency affect network games? What are precision and deadline? How do precision and deadline pertain to latency and games?
