Chapter 5: Network and Transport Layer Flashcards
IPV4 Public Address Space - IPV4 uses 32 bits (4 bytes) to define an address. - Therefore, the number of available addresses is 232 = 4,294, 967, 296 or approxiamtely 4.3 billion - These addresses in the IPv4 address space are divided into Internet address classes. - As we Ping command to test connectivity after configuration with the required IP addresses, the command uses the most basic interior routing protocol on the Internet which is Internet Control Message Protocol. Subnet: is a group o (20 cards)
The network layer sits directly between the application layer and the data link layer in the Internet five-layer network model. (TRUE/FALSE)?
False
TCP/IP is the data link protocol that is used on the Internet. (TRUE/FALSE)?
False
The network layer provides gauranteed end-to-end delivery of the message. (TRUE/FALSE)?
False
The blank layer links the application layer with the network layer is responsible for end-to-end delivery of messages
Transport
blank is not an important function of the transport layer
Routing
Transmission Control Protocol/Internet Protocol was developed for “blank” in 1974
ARPANET
A typical TCP segment has a blank header of control information
192-bit
Stop-and-wait ARQ uses blank type of data flow
Half duplex
What are the twyp types of ARQ?
Stop-and-wait and continuous
A subnet mask of 255.255.255.0 means that all computers with only the same first two bytes in their IPv4 addresses are on the same subnet. (TRUE/FALSE)?
False
A subnet mask of 255.255.0.0, the first two bytes indicate the same subnet. (TRUE/FALSE)?
True
UDP is not commonly used for:
a. network management control messages
b. RIP messages
c. DHCP addressing messages
d. HTTP requests
e. DNS requests
d. HTTP requests

What is a Subnet?
A group of computers that are logically grouped together by IP number
