ISO
The International Organization for Standardization In networking, ISO is best known for its Open Systems Interconnection (OSI) reference model. ISO published the OSI reference model in 1984 to develop a layered framework for networking protocols
IANA
The Internet Assigned Numbers Authority department of ICANN responsible for overseeing and managing IP address allocation, domain name management, and protocol identifiers for ICANN
Which statement is true about the TCP/IP and OSI models?
The TCP/IP transport layer and OSI Layer 4 provide similar services and functions.
Which statement is true about the TCP/IP and OSI models?
The TCP/IP transport layer and OSI Layer 4 provide similar services and functions.
Which protocol is used by a computer to find the MAC address of the default gateway on an Ethernet network?
**ARP**
Open the PT Activity. Perform the tasks in the activity instructions and then answer the question. Based on the configured network, what IP address would PC1 and PC2 use as their default gateway?
192.168.1.1

192.168.1.1
Which IEEE standard enables a wireless NIC to connect to a wireless AP that is made by a different manufacturer?
802.11
What is an advantage of network devices using open standard protocols?
A client host and a server running different operating systems can successfully exchange data.
What statement describes the function of the Address Resolution Protocol?
ARP is used to discover the MAC address of any host on the local network.
Which PDU format is used when bits are received from the network medium by the NIC of a host?
Frame
A web client is sending a request for a webpage to a web server. From the perspective of the client, what is the correct order of the protocol stack that is used to prepare the request for transmission?
HTTP, TCP, IP, Ethernet
ISOC
Is an international standards and trade organization for electronics organizations. It is best known for its standards related to electrical wiring, connectors, and the 19-inch racks used to mount networking equipment
A computer in a given network is communicating with a specific group of computers. What type of communication is this?
Multicast
At which layer of the OSI model would a logical address be encapsulated?
Network layer
Which statement accurately describes a TCP/IP encapsulation process when a PC is sending data to the network?
Segments are sent from the transport layer to the internet layer.
A user is viewing an HTML document located on a web server. What protocol segments the messages and manages the segments in the individual conversation between the web server and the web client?
TCP
Which protocol is responsible for controlling the size and rate of the HTTP messages exchanged between server and client?
TCP
If the default gateway is configured incorrectly on the host, what is the impact on communications?
The host can communicate with other hosts on the local network, but is unable to communicate with hosts on remote networks.
Which address does a NIC use when deciding whether to accept a frame?
destination MAC address
What method can be used by two computers to ensure that packets are not dropped because too much data is being sent too quickly?
flow control
What is a benefit of using a layered model for network communications?
fostering competition among device and software vendors by enforcing the compatibility of their products
Which PDU format is used when bits are received from the network medium by the NIC of a host?
frame
IEEE
is a professional organization for those in the electrical engineering and electronics fields. It creates and maintains standards affecting a wide range of industries including telecommunications, and networking.
EIA
is an international standards and trade organization for electronics organizations. It is best known for its standards related to electrical wiring, connectors, and the 19-inch racks used to mount networking equipment.
Which address provides a unique host address for data communications at the internet layer?
logical address
A computer in a given network is communicating with a specific group of computers. What type of communication is this?
multicast
At which layer of the OSI model would a logical address be encapsulated?
network layer
What is the general term that is used to describe a piece of data at any layer of a networking model?
protocol data unit
hat is the general term that is used to describe a piece of data at any layer of a networking model?
protocol data unit
What are proprietary protocols?
protocols developed by organizations who have control over their definition and operation
What is a function of Layer 4 of the OSI model
to describe the ordered and reliable delivery of data between source and destination
What is a function of Layer 4 of the OSI model?
to describe the ordered and reliable delivery of data between source and destination
A user sends an HTTP request to a web server on a remote network. During encapsulation for this request, what information is added to the address field of a frame to indicate the destination?
the MAC address of the default gateway
