Hard/Software – chap 14

The Telnet protocol encrypts transmitted data, which therefore cannot be read by others on the network.
When using static IP addressing, software automatically configures the network connection on each device.
A problem with virtual networks is that data transmitting through them cannot be encrypted and therefore is not secure.
The User Datagram Protocol (UDP) guarantees delivery of data to its destination.
The current release of SMB is CIFS, also called SMB2.

How is the network portion and the host portion of an IP address identified?
subnet mask
What command can be used to display IP addresses assigned to all network connections on a system?
Packets are delivered to a single node on a network when using what type of IPv6 address?

What protocol makes a connection, checks whether the data is received, and resends it if it is not?
The solution for securing private data traveling over a public network, such as the Internet, is the use of what type of network?
virtual private network
Originally developed by IBM, what protocol is used by Windows to share files and printers on a network?

What two protocols are used to deliver mail messages?


What two terms are used to describe the User Datagram Protocol (UDP)?
best effort protocol

connectionless protocol

What two protocols are used for remote access to a server, using unencrypted and encrypted transmissions respectively?


assigns an IP address to a computer when it first attempts to initiate a connection to the network
DHCP server
A group of computers on a peer-to-peer network that are sharing resources
commonly used by Linux to pass sign-in information to a remote computer and control that computer over a network
Secure Shell (SSH)
designed to make it easier for users to connect their computers to a wireless network when a hard-to-remember SSID and security key are used
Wi-Fi Protected Setup (WPS)
Used by a computer or other device to determine if an IP address of another computer is on its network or another network
subnet mask
identifies a computer and the network to which it belongs, such as www.cengage.com
Fully Qualified Domain Name (FQDN)
a protocol used by various client applications when the application needs to query a database
Lightweight Directory Access Protocol (LDAP)
a command that can be used to display the TCP/IP configuration
protects data by encrypting it from the time it leaves a remote computer until it reaches a server on a corporate network, using a technique called tunneling.
virtual private network
a technique designed to conserve the number of public IP addresses needed by a network
Network Address Translation (NAT)
