TCP / IP

• TCP / IP
• Comparison of the OSI Model and TCP / IP
• Encapsulation and layering in TCP / IP
• Application layer in TCP / IP
• Transport layer in TCP / IP
• Network layer in TCP / IP
• Physical layer in the TCP / IP

TCP / IP

Is the de facto protocol used on the internet (a global computer network)

Protocol refers to the OSI (Open system Interconnect)

Comparison of the OSI Model and TCP / IP

Transport layer

• Package to ensure the correct service (Port)
• Control the whole process of transmission, when it started, accelerated, slowed, terminated (Code Bit)
• Find out if there is damage to the transmission of data (checksum)
• The numbering of the data packets so that data can be reordered (Sequence number)

The types of protocol at the transport layer

• TCP (Transmission Control Protocol)
• is connection oriented
• UDP (User Datagram Protocol)
• are connectionless oriented

Protocols at the network layer

IP (Internet Protocol)

•  For transmission of data packets

ICMP (Internet Connection Message Protocol)

• For information on network conditions, for example: ping, traceroute

ARP (Address Resolution Protocol)

• Getting the MAC Address of IP information that is known

RARP (Reserve ARP)

• Get IP information from a known MAC address

Internet Protocol

• Ensure the data packet to the destination computer
• TCP at the transport layer protocol and IP backbone network dilayer TCP / IP

ICMP

• Used for diagnosis
• network conditions

ARP

• Map the IP to MAC Address

Network Layer Interface / Data link and phisycal

• Transmits the datagram from the network layer to the destination host
• Technology: Ethernet, Point to Point Protocol (PPP), etc.
• Ethernet technology is a technology that is widely used
• Ethernet addresses called MAC (Media Access Control) Address
