Networking Flashcards
A twisted pair wire of less than 100 yards that can carry data at more than 100mbps is a _____.
Cat-5
A computer language translator for information coming into a network that is often paired with a firewall is called a _____.
Modem
The connector terminating the ends of every network patch cable whose name contains two letters and two numbers is _____.
RJ-45
A boxy device with multiple ports that connect network hardware together and provide a bridge for data to travel over, but do not regulate the traffic or direct the traffic to any specific location. They are called a _____.
Hub
A(n) _____ is a boxy device with multiple ports that connect network hardware together. When data packets flow through them, they can manage the data traffic as a 4-way stop sign would at some intersections.
Switch
A(n) _____ is a boxy device with multiple ports that connect network hardware together. Not only can it direct and regulate traffic, but it can be programmed to respond to different network needs and can send specific types of data to specific places on the network. They are like a traffic cop directing traffic at an intersection.
Internet Router
A super highway for data traffic in large networks that is compared to as an important human body part that has a similar function is called the _____.
Internet Backbone
_____ is a twisted pair copper wire that is capable of transferring data at speeds from 500mbps to 1000mbps over short distances and is the new standard for wired networks.
Cat-6
_____ is a computer component with a jack for a network cable. It is the hardware interface between a computer and the wired or wireless network.
NIC (Network Interface Card)
A wire with an optically pure glass core that can transfer data very quickly over long distances on the back of bouncing light particles is called a(n) _____.
Fiber Optic
A robust computer that is designed to manage requests for services or information from other computers on a network and is new and powerful at HVA is called a(n) _____.
Server
A network cable that has jacks at both ends and can be used to easily connect or disconnet network devices is called a(n) _____.
Ethernet Cable
_____ is a group of interconnected disks that are often used for backup or speed on a network.
RAID (Redundant Array of Interconnected Disks)
A _____ is a device that translates signals between the analog and digital world. Without it, no one would be able to receive or send data over the internet in their homes.
Gateway
Why is a twisted pair, twisted?
Wires are twisted to keep electromagnetic interference from entering and deleting data. Just like TV antennas stop ‘frizz’ from happening.
What does the protocol TCP/IP do?
TCP/IP splits data into packets and then decides where the pieces are sent to.
What does TCP stand for and what does it do?
TCP stands for Transmission Control Protocol. It breaks up data into packets at the beginning of the process and then reassembles them at the end.
What does IP stand for and what does it do?
IP stands for Internet Protocol. It addresses each data packet which shows them how to get to the correct computer or place.
What numbers does the IP Address 4 use when addressing data packets?
0-255; Example: 192.168.7.41
What happens when you search something on the internet?
A request is made to a server warehouse until the information is found. Then, TCP/IP breaks up the information into packets, sends it to your computer, and reassembles it into a picture.
Are all data packets the same size?
No, their size varies upon their content.
A computer that provides multiple services is called a(n) _____.
Server
What are the three sizes of networks?
LAN, MAN, and WAN
What network size is the smallest and which is the largest?
The smallest network size is a LAN. The largest network size is a WAN.
