Port forwarding
POTS stands for?
Plain Old Telephone Service
CRT stands for?
Cathode Ray Tube
This tool is a device used to conjoin two pieces of metal by deforming one or both of them in a way that causes them to hold each other.
Crimper
After a resource on your LAN sends outbound traffic through a “trigger” port, the router listens for inbound traffic through a specified port or port range. This function is necessary for applications, such as videoconferencing or gaming, that require data exchange through specified ports. What is this referred to as?
Port triggering
You work as a Network Administrator for De Laurentis Unlimited Inc. The company has a TCP/IP-based network. You are configuring a cable modem on the network to connect to the Internet. Which of the following types of connectors are supported by the cable modem? Choose all that apply. a. RJ-45 b. F-type c. USB d. MT-RJ
a. RJ-45 b. F-type c. USB
These are the Internet’s equivalent of a phone book. They maintain a directory of domain names and translate them to Internet Protocol (IP) addresses.
DNS (Domain Name Server(s))
This device simulates a network connection and has two main functions: Used to test ports and data flow from one source to another.
Loopback plug
In computer networking ________ refers to a security access control method whereby the 48-bit address assigned to each network card is used to determine access to the network.
MAC filtering
This layer is where router operates.
Network layer
IPv6 addresses are broken down into three sections:
Global routing prefix (2001:7120:0000) A subnet (80010) The Individual interface ID (0000:0000:0000:1F10)
A tool used for inserting wire into insulation-displacement connectors on punch down blocks, patch panels, keystone modules, and surface mount boxes (also known as biscuit jacks).
Punchdown tool
Used to verify the electrical connections in a cable or other wired assembly
Cable Tester
This layer is responsible for creating and maintaining sessions between operating system and presentation layer + other third party machines.
Session layer
This layer is where user inputs data and data is output to user. Usually software; depends on network architecture.
Application layer
This RAID has the highest fault tolerance.
RAID 5
SFTP stands for?
Secure File Transfer Protocol
Which OSI layer signals “all clear” by making sure the data segments are error free?
Transport layer
This layer is responsible for logistics of the session.
Transport layer
This is a type of digital audio interconnect used in consumer audio equipment to output audio over reasonably short distances. The signal is transmitted over either a coaxial cable with RCA connectors or a fiber optic cable with TOSLINK connectors.
S/PDIF
This layer is where the operating system lies (Windows, OS X, etc.).
Presentation Layer
This layer is the hardware that makes up network.
Physical layer
