There are no switches that operate on layer 7 (Application layer) on the OSI Model. Switches are a layer-2 device because they manage and switch frames.
None, they communicate to the layer 7, however they do not operate at that layer(application)
Layer 7, Aplication
IP operates at layer 3, this is the NETWORK LAYER in the OSI Model. Network+ Guide to Networks Fifth Edition Ch02, pg56, Figure 2-7
TCP operates at Layer 4 which is Transport of the OSI Model!
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.

DNS is an application layer protocol. The application layer of the OSI model is the layer closest to the user and provides network services to the applications of the user. Examples of protocols that operate at the application layer are: DNS, FTP, TFTP, SNMP, TELNET, RLOGIN, SMTP, MIME, NFS, FINGER, BOOTP and SMB.
The tectonic plates which form Earth's crust move on top of the outer layer of the mantle. This layer of the mantle is known as the asthenosphere.
It's called the OSI Model... it has 7 layers. 1) Physical Layer 2) Data Link Layer 3) Network Layer 4) Transport Layer 5) Session Layer 6) Presentation Layer 7) Application Layer
To program a 9 dip switch garage door opener with a 7 dip switch remote, first, locate the dip switch settings on both devices. Set the 7 dip switches on the remote to match the first 7 switches of the 9 dip switch opener, leaving the last two switches on the opener either in the off position or using a combination that matches the opener's configuration. Once set, press the remote button while near the opener to pair them. Finally, test the remote to ensure it operates the garage door correctly.
Internet Explorer (IE) primarily operates at the Application Layer (Layer 7) of the OSI model. This layer is responsible for providing network services to applications, enabling web browsing, email, and file transfers. While IE interacts with other OSI layers for data transport, its core functionality is focused on the user interface and application-level protocols like HTTP.
