I. TCP/IP protocols Summary
1. IP - a connectionless protocol used to move data around a network at Network Layer 3.
2. TCP-Connection oriented protocol that offers flow control, sequencing and retransmission of
dropped packets at Transport Layer 3.
3. UDP-A Connectionless alternative to TCP used for applications that do not require the
functions offered by TCP at Transport Layer 4.
4. FTP- protocol for Uploads and downloads files to and from a remote host. Also
accommodates basic file-management task at Application Layer 7.
5. Trivial FTP(TFTP)- FTP that does not have the security or error-checking capability of FTP;
uses UDP as a transport protocol and is therefore connectionless

II. OSI Layer Summary
1. Application layer-where application reside.it is the end user interface to the operating
system(UNIX, LINUX, …)
 responsible for identifying communications partners
 The application Layer is where the user/applications access the network
2. Presentation layer –converts data from the application into a common interchangeable
format
 translate data from a format used by the application layer into a common format at the
sending station, then translate the common format to a format known to the application layer
at the receiving station
 Data encryption translates the data into another form or code
 The presentation layer provides:
Character code translation: for example, ASCII to EBCDIC.
Data conversion: bit order, integer-floating point, and so on.
Data compression: reduces the number of bits that need to be transmitted on the network.
Data encryption: encrypt data for security purposes. For example, password encryption.
3. Session layer- organizes and synchronizes the exchange of data between application
processes
 Timing and flow control layer
 It establishes, maintains, and terminates communications between applications located on
different devices
 This layer allows a process to add checkpoints which are considered as synchronization
points into the data
 The session layer determines which device will communicate first and the amount of data
that will be sent.
4.Transport layer- provides transfer of data from a source end system to a destination end open system
 ensures that messages are delivered error-free, in sequence, and with no losses or
duplication
 Provides for both reliable and unreliable delivery and error correction before retransmit.
 Provides reliable end-to-end message delivery with acknowledgments.
5. Network layer- provides physical routing of the data, determining the path between the
systems
 Provides logical addressing which device use for path destinations.
 The network layer protocols determine which route is suitable from source to destination
 Routing: routes frames among networks.
 Translates logical addresses, or names, into physical addresses.

Integrated, Standard Primary, and Standard Secondary. AD Integrated stores the database
information in AD and allows for secure updates to the database file.
 Standard Primary zone-stores the database in a text file. This text file can be shared with
other DNS servers that store their information in a text file.
 Standard Secondary zone- creates a copy of the existing database from another DNS server.
