SMB
Application layer protocol that is used to provide file-sharing and print services to Microsoft applications
POP3
Application layer protocol that uses message types such as GET, PUT and POST
-FTP -HTTP -SMTP
A manufacturing company subscribes to certain hosted services from its ISP. The services that are required include hosted world wide web, file transfer, and e-mail. Which protocols represent these three key applications?
IMAP
A protocol that allows for easy, centralized storage and backup emails that would be desirable for a small-to medium sized business.
IMAP (Internet Message Access Protocol)
A standard email protocol that stores email messages on a mail server, but allows the end user to view and manipulate the messages as though they were stored locally on the end user's computing device(s).
POP (Post Office Protocol)
A type of computer networking and Internet standard protocol that extracts and retrieves email from a remote mail server for access by the host machine. POP is an application layer protocol in the OSI model that provides end users the ability to fetch and receive email.
A workstation initiates a DNS request when the user types www.cisco.com in the address bar of a web browser.
An example of network communication that uses the client-server model.
HTTPS
An internet communication protocol that protects the integrity and confidentiality of data between the user's computer and the site. Users expect a secure and private online experience when using a website.
Server Message Block Protocol
Clients establish a long term connection to servers.
Application Layer
Layer of the TCP/IP model that is used for formatting, compressing and encrypting data
GET
Message type used by an HTTP client to request data from a web server.
TCP/IP Application Layer
OSI Session, Presentation and Application Layers
.com
Part of the URL, http://www.cisco.com/index.html, represents the top-level DNS domain
Telnet
Provide remote access to servers & networking devices
FTP
The client can download data from or upload data to the server.
to manually query the name servers to resolve a given host name
The function of the Nslookup utility
-The destination IP address is 255.255.255.255. -The message comes from a client seeking an IP address. -All hosts receive the message, but only a DHCP server replies.
Three statements that describe a DHCP Discover message.
-the creation and maintenance of dialogue between source and destination applications -closest to the end user
Two characteristics of the application layer of the TCP/IP model.
Peer to peer
Two students are working on a network design project. One student is doing the drawing, while the other student is writing the proposal. The drawing is finished and the student wants to share the folder that contains the drawing so that the other student can access the file and copy it to a USB drive. Which networking model is being used?
-mapping name-to-IP addresses for internal hosts -forwarding name resolution requests between servers
Two tasks that can be performed by a local DNS server
Both models support devices in server and client roles.
What do the client/server and peer-to-peer network models have in common?
IMAP
allows viewing of messages on email clients
HTTP
displays web pages
DHCP
dynamically assigns IP addresses to clients
DNS
maps URLs to numerical addresses
DNS
resolves Internet names to IP addresses
SMTP
sends email messages
