    “Some applications involve spatially separated machines. For example, a supermarket chain may have many stores.

    What is an Autonomous system/ computing?
    • A. 

      A network that is administered by a single set of management rules that are controlled by one person, group or organization. Autonomous systems often use only one routing protocol, although multiple protocols can be used. The core of the Internet is made up of many autonomous systems.

    • B. 

      Autonomic Computing refers to the self-managing characteristics of distributed computing resources, adapting to unpredictable changes whilst hiding intrinsic complexity to operators and users.

    • C. 

      Referring to a group of routers within the same administrative domain. The term is used in exterior protocols such as the Exterior Gateway Protocol (EGP) and the Border Gateway Protocol (BGP)

      100 m

    • C. 

      1 km

      True

    • B. 

      False

    Scalability basically refers to the size of the network that is to be used and it consists of various sizes. Thus this may create some problems in the network. To solve the scalability problem, there are basically three techniques for scaling which are hiding communication latencies, distribution, and replication. 
    • A. 

      True

    • B. 

      False

  • 17. 
    Circuit switching is when a message or data is broken into packets and are routed independently. It also has better network utilization. Meanwhile, packet switching is a dedicated path between a source and a destination e.g., telephone connection. It wastes bandwidth. True or false? 
    • A. 

      True

    • B. 

      False

  • 18. 
    Distribution involves taking a component, splitting it into smaller parts, and subsequently spreading those parts across the system. A good example of distribution is the Internet Domain Name System (DNS). State true or false. 
    • A. 

      True

    • B. 

      False

  • 19. 
    The implementation of caching and replication DOES NOT lead to consistency problems. State true or false.

      True

    • B. 

      False

  • 20. 
    State true or false- Concurrency is one of the intrinsic characteristics of distributed systems. There are two reasons for parallel executions to occur: 1. Many users concurrently invoke commands or interact with (the same) application programs. 2. Many server processes run concurrently, each corresponding to multiple request from a client process.
    • A. 

      True

    • B. 

      False

  • 21. 
    Peer processes model is a distributed application based on peer processes. Sometimes, some processes play similar roles, interacting cooperatively as peers to perform a task. This model is usually used because of the nature of the application, e.g., group communication. State true or false. 
    • A. 

      True

    • B. 

      False
