Linking two or more computers together within a company to facilitate sharing of information is called a
Network
Shared space
Ethernet
Bandwidth
Which is not an advantage of Local Area Networks (LAN)
Shared Information
Shared Space
Shared Hardware
Shared Storage Devices
Bandwidth is
rate at which a carrier can share its data
rate at which a radio frequency is carried across cable lines
A "collision" is when
Two or more Ethernet computers attempt to write data at the same time
Two or more Ethernet computers attempt to sense data at the same time
Exponential Backoff is
Waiting one more second each attempt to write data
Using exponentially faster bandwith to write data on the ethernet
Using exponentially longer wait time to write date on the Ethernet
The device that separates collision domains is called a
Ethernet
Switch
Router
Allocating a communication line for the use of two end users is called
Routing
Switching
Networking
The number of route segments a message has taken is called the
Hop limit
Hop count
IP stands for
Internet packet
Internet protocol
The potential problem with "packet switching" is
Packets take too long at any one router
Packets may arrive at the destination out of order
What is your LAN (local area network)?
Every device in your home connected to your wi-fi router.
A global system of interconnected computer networks.
A computer network that extends over a large geographic area.
What does the traceroute program on your computer do?
It is a mapping program on your computer that shows the route you traveled in one day.
It is a network tool used to show the route taken by packets across an IP (internet protocol) network.
What is IP?
A low level protocol consisting of a destination address in the packet header and a data payload.
A communication protocol used across the Internet for especially time-sensitive transmissions such as video playback or DNS lookups. It speeds up communication by not requiring a handshake.
A communication protocol commonly used for loading web page content that requires a handshake in which the receiver agrees to the communication before the data is sent.
Which of the following correctly states the roles of IP and UDP?
UDP gets the packet to the right computer, but IP gets the packet to the right program running on that computer.
IP gets the packet to the right computer, but UDP gets the packet to the right program running on that computer.
Which of the following is an advantage of TCP/IP?
It is limited to back and forth data conversations.
It can receive data packets out of order.
It does not have a mechanism for data congestion control.
What information is needed for a computer to connect to a website?
an IP address
a port number
an IP address AND a port number
What is DNS (Domain Name System)?
The phonebook of the Internet, mapping domain names to IP addresses
a communication protocol used across the Internet for especially time-sensitive transmissions
a set of standardized rules that allow computers to communicate on a network
