Application Layer
The function of the application layer is to interface between an external program application and the network stack. As such it has to build the first part of the packet that describes the protocol being used in the network. There are a series of API (application Program Interfaces) which allows a software developer to interface with the OSI layers without knowing anything about how to network.
Telnet is an application layer protocol (Layer 7). Its functionality is similar to any of the layer 7 protocols, including DHCP, DNS, FTP, etc.
TELNET operates at Application Layer in TCP/IP Model. It's an Application to establish a connection to TCP Port Number 23, where a Telnet server application (telnetd) is listening.
