- File Transfer Protocol
- File exchange
- Authenticates with a username and password
- Full featured functionality (list, add, delete, etc.)
A type of cryptographic network protocol for secure data communication, remote command-line login, remote command execution, and other secure network services between two networked computers is known as:
-SSH (Secure Shell)
What does Telnet allow?
- Provides username & password authentication
- Transmits data in an unencrypted form
- Enables remote login and command execution
- Console access
The SMTP protocol is used for:
- Sending email messages from a client device
- Sending email messages between mail servers
What describes a system that maps domain names to various types of data, such as numerical IP addresses?
-DNS (Domain Name System)
Which network protocol enables users to retrieve the contents of an Internet page from a web server?
-HTTP (Hypertext Transfer Protocol)
What is the function of POP3?
-Email retrieval
IMAP is used for:

-HTTPS (Hypertext Transfer Protocol Secure)
Which of the following is a Microsoft-proprietary remote-access protocol providing users with a graphical interface that allows them to connect to another computer on a network?
-RDP (Remote Desktop Protocol)
What is used when a WINS server tries to resolve a host name into an IP address on a Windows-based LAN?
-NetBIOS
True or False
The function of the NetBT protocol is to allow NetBIOS services to be used over TCP/IP networks.
-True
Characteristic features of SMB/CIFS?
- Used mainly by computers running Microsoft Windows operating systems
- Provides shared access to files, directories, and devices
What protocols permits automated discovery of networked services on Local Area Networks (LANs)?
-SLP (Service Location Protocol)
Name a file sharing network protocol?
- AFP (Apple Filing Protocol)
- SMB (Server Message Block)
- CIFS (Common Internet File System) (this is SMB)
- NetBIOS
- FTP (File Transfer Protocol)
A network protocol providing an alternative solution to the manual allocation of IP addresses is known as:
-DHCP (Dynamic Host Configuration Protocol)
LDAP is an example of a(n):
-Directory access protocol
A type of protocol used in network management systems to monitor network-attached devices is called:
-SNMP (Simple Network Management Protocol)
What does TCP mean, do, and what are some aspects of it?
- Transmission Control Protocol
- TCP transfers packets using IP
- Connection-oriented
- A session is started, sender and receiver communicate on data being sent
- If data sent is corrupted, the receiver doesn’t acknowledge it and the sender resends
What does UDP mean, do, and what are some aspects of it?
- User Datagram Protocol
- UDP transfers packets using IP
- speed and simplicity, connectionless (no session started, data is sent and received with no acknowledgement)
- no error checking because no acknowledgement
What does SSH mean? What is it?
- Secure Shell
- Encrypted communication link that allows remote logins
- A user can connect to a server to transfer information in a more secure manner than other methods
What does a client use to receive email?
- IMAP4 (Internet Message Access Protocol v4)
- POP3 (Post Office Protocol Version 3)
Advantage of IMAP4 over POP3?
-Includes management of email inbox from multiple clients
What does RDP mean and what does it do?
- Remote Desktop Protocol
- Share a desktop or application from a remote location
What does DNS mean and what does it do?
- Domain Name System
- Converts names to IP addresses
What does SLP mean and what does it do?
- Service Location Protocol
- It allows clients to locate servers and other services on the network.
What does SNMP mean and what does it do?
- Simple Network Management Protocol
- Gather stats from network devices
- SNMP examines and changes configuration parameters of LAN and WAN connected repeaters, bridges, routers, switches, and other devices connected to a network.
What does LDAP mean and what does it do?
- Lightweight Directory Access Protocol
- Store and retrieve information in a network directory
True or False
Is LDAP commonly used in Microsoft Active Directory?
-True
What does DHCP mean and what does it do?
- Dynamic Host Configuration Protocol
- Auto configs IP address, subnet mask and other options
- Dynamic, meaning IP addresses are assigned in real-time from a pool
- Each system is given a lease and must renew at set intervals
What is DHCP reservation?
- Can reserve IP addresses by using MAC address in the DHCP server
- Quickly manage addresses from one location
What does NetBIOS do?
- Allows computers and applications to communicate with network hardware, and allows data to transmit properly over a network
- Older systems use this, newer systems use SMB
What does SMB mean and what does it do?
- Server Message Block
- Common network communications method used on Microsoft operating systems allowing those computers to communicate with other SMB computers. AKA File sharing, printer sharing, etc.
- Like NetBIOS but modern and better
What is CIFS?
- SMB (Server Message Block)
- File sharing over IP between computers that use it
What does AFP mean and what does it do?
- Apple Filing Protocol
- File sharing between systems that use it.
- Used in Apple systems
- Works with SLP (Service Location Protocol)
What is Telnet?
- Telecommunication Network
- A terminal emulation that enables a user to connect to a remote host or device using a telnet client.
- Unencrypted, data is transmitted in clear text
- SSH is similar but SSH is encrypted
