Net Programming (Client Server Model (To create simple server (Create…

- - - - Connect to machine
      - Send Data
      - Receive data
      - Close connection
      - Bind to port
      - Listen for incoming data
      - Accept remote connections on bound port
  - - - Not guaranteed - uses best effort
      - Client/server requests may be lost, delayed, duplicated or out of order.
      - Low latency: for video, games etc
    - - Provides reliability across internet
      - Checks errors and retransmits
      - Sequence numbers to ensure order
- - - - SMTP
        
        For sending/receiving emails
      - Telnet
        
        Standard application Remote Login (unsecure)
      - SSH(Secure Shell)
        
        Remote Login(Secure)
      - Http
        
        Deliver data on web. TCP/IP bases connection.
      - DNS
        
        Phonebook of domain names.
        Contains names and translates to IP addresses
      - FTP
        
        File Transfer between computers.
        Can upload, download, delete, copy files from a server.
        Name and password required unless on anonymous ftp
- - - - One request at a time.
        Easier to build and understand.
        may have poor performance.
    - - More than one request at a time. Better Performance. More programming effect?
    - - TCP Transfer Protocol. TCP Handles errors, packet loss, out-of-order delivery.
        On start tcp will deliver and receive all requests or infrom server connection down.
        Simplifies programming
    - - UDP Transport protocol. Not responsible for reliability. Multicast and broadcast communication.
- - - - Light weight processes in threads
      - Way of creating threads
        
        Extending the thread class
        
        Implementing the runnable interface
