What is an access point?
A network that connects devices using wire cables in a small geographical area.
What is LAN?
Server that would support the SMTP, POP, and IMAP protocols.
HTTP
What is port 80?
Two common devices powered by POE
What is access point and IP phone?
Connector is used to connect an analog modem to a telephone line socket.
What is RJ 11?
What is PAN?
802.11n operates in this/these frequencies.
5 GHz & 2.4 GHz

Networking device that fowards data based on MAC address.
What is a switch?
Pairs of wires change termination order between the 568A and 568B.
What is green and orange?

What is port 22?
Three devices that make a multipurpose network.
What is a router, switch, and access point?
A cable that is not affected by EMI?
What is fiber optic cable?
Optical fiber uses light to transmit signals. Therefore, fiber-optic cable is not affected by EMI or RFI.
Uses multiple access points to extend the WLAN.
What is WMN, Wireless mesh network?
Max number of devices Bluetooth supports.
127,7,10,24,5
What is 7 devices?
Bluetooth is a short range wireless technology that is used for personal area network (PAN) devices such as cell phones, keyboards, headsets, and mice. A Bluetooth device can connect to a maximum of seven other devices using this 2.4 GHz technology.
Clients access DHCP through this port.
What is port 68?
Provide stateful packet filtering, email filtering, and VPN services.
What is UTM?
A universal threat management (UTM) device is an all-in-one security device that can provide firewall, proxy filtering, email filtering, and network access control services as well as be a point where remote users connect to the company using a VPN.
Interference is reduced more by STP than by UTP.
rfi,white noise, mdf, dispersion,emi, ssh
What is RFI & EMI?
RFI, EMI, and crosstalk cause interference to the electrical signals that are transmitted through copper cables. Both UTP and STP use twisted pairs of wires that help protect against crosstalk. However, STP provides greater protection against RFI and EMI than UTP provides.
Used to securely connect to another network over an insecure network, such as the internet.
What is VPN, virtual private network?
Correct order of TCP/IP model.
application, transport, internet, network access

PC is using multiple applications, what technology keeps track of the data flow between multiple application sessions?
What is source ports?
The source port number of an application is randomly generated and used to individually keep track of each session connecting out to the Internet. Each application will use a unique source port number to provide simultaneous communication from multiple applications through the Internet.
