Chapter 17 | Networking 17.1 Explain what happens, step by step, after you type a URL into a browser. Use as much detail as possible. ________________________________________________________________pg 249 17.2 Explain any common routing protocol in detail. For example: BGP, OSPF, RIP. ________________________________________________________________pg 250 17.3 Compare and contrast the IPv4 and IPv6 protocols. ________________________________________________________________pg 252 17.4 What is a network / subnet mask? Explain how host A sends a message / packet to host B when: (a) both are on same network and (b) both are on different networks. Explain which layer makes the routing decision and how. ________________________________________________________________pg 254 17.5 What are the differences between TCP and UDP? Explain how TCP handles reliable delivery (explain ACK mechanism), flow control (explain TCP sender’s / receiver’s window) and congestion control. ________________________________________________________________pg 255 CareerCup.com 8 4
Chapter 18 | Threads and Locks How to Approach: In a Microsoft, Google or Amazon interview, it’s not terribly common to be asked to implement an algorithm with threads (unless you’re working in a team for which this is a particularly important skill). It is, however, relatively common for interviewers at any company to assess your general understanding of threads, particularly your understanding of deadlocks Deadlock Conditions In order for a deadlock to occur, you must have the following four conditions met: 1. Mutual Exclusion: Only one process can use a resource at a given time. 2. Hold and Wait: Processes already holding a resource can request new ones. 3. No Preemption: One process cannot forcibly remove another process’ resource. 4. Circular Wait: Two or more processes form a circular chain where each process is waiting on another resource in the chain. Deadlock Prevention Deadlock prevention essentially entails removing one of the above conditions, but many of these conditions are difficult to satisfy. For instance, removing #1 is difficult because many resources can only be used by one process at a time (printers, etc). Most deadlock prevention algorithms focus on avoiding condition #4: circular wait. If you aren’t familiar with these concepts, please read http://en.wikipedia.org/wiki/Deadlock.
