Could you please help me on these OSI Model Layer and TCP/IP Model Layer network questions. I really appreciate your help

(Type of Info Handled	OSI Model Layer	TCP/IP Protocol Suite	Devices	TCP/IP Model Layer
Do (data)	Applications	Telnet,FTP,TFTP,SMTP,DNS,RIP	Fateway and Proxy Server	Application
Do (data)	Presentation	Telnet,FTP,TFTP,SMTT	Gateway and Redirector Encryption happens here	Application
Do (data)	Session	Telnet,FTP,TFTP,SMTP	Gateway Router	Application
Sergeants(segments)	Transport	TCP, UDP	Gateway Router	Transport
Pay(packets and datagrams	Network	IP,ICMP,IGMP,ARP,OSPF,RIP	Router	Network
For(frames)	Data Link LLC Sublayer	PPP,SLIP,ARP	Logical Link Control Sublayer Device=Switch IEEE 802.1 OSI model and network management IEEE 802.2 Logical Link Control	Data Link
For(frames)	Data Link MAC sublayer	NIC driver NDIS WEP (Wired Equivalent Privach)	Media Access Control Sublayer Device=Bridge IEEE 802.3 Ethernel (CSMA/CD)	Data Link
Beer? (bits and signals)	Physical	Repealer, hub,NIC,cable,transceiver,multiplexer,MAU	Repeater,hub,NIC,cable,transcalver,multiplexer,MAU	Physical

(Remember! The UDP and IP protocols are connectionless!
