binary math
what is the meaning of binary
Binary means a single bit that can either be 0 or 1.
what are the three important addresses you need to configure when configuring ipv4 on a computer
IP address, subnet mask and default gateway
what are the private IP addresses that you need to know?
he first range is 10.0.0.0 through 10.255.255.255. The second range is 172.16.0.0 through 172.31.255.255. The last private IP address range is 192.168.0.0 through 192.168.255.255.
What is the meaning of unicast
. Unicast means that one device is sending information directly to another device
what is a bytes
A byte is equal to 8 bits
What is an IP addresses
This is an address that uniquely identifies this device on the network
how are we able to have all of these devices communicating on the internet without actually having enough IP addresses?
We’re able to use a technique called Network Address Translation, or NAT.
when is a unicast communication used
when you’re connecting to a web server or you’re performing a file transfer
what is the equivalence of 10000010 in decimal
10000010 is equal to 130 in decimal
What is a subnet mask
This is a number that is used in conjunction with your IP address so that your device understands what IP subnet it happens to live on.
what is network translation
Very simply, network address translation is when a device changes an IP address as it’s communicating through the network.
one way to send traffic to multiple devices on the network simultaneously
One of these ways is to use broadcast communication where one device can send one piece of information.
what is the equivalence of 128 in binary
128 in binary is equal to 10000000.
what is the default gateway
This is an IP address that is on the same local subnet as your IP address because this is where you’re going to be sending all of the traffic that needs to go outside of this local subnet.
what to do when you have multiple IP addresses or even tens, hundreds, or thousands of devices that need to communicate?
n that situation, you’ll perform a special kind of network address translation called a source network address translation, a NAT overload, or a port address translation.
why is multicast used instead of broadcast in pv6
Multicast allows you to send a single frame that would only be seen by devices that are interested in receiving that information, and other devices that aren’t involved in that communication are not affected by a multicast.
what is 154 in binary number
154 is equal to 10011010
What is DNS
DNSstan for domain name system server
what is multicast communication
In computer networking, multicast is group communication where data transmission is addressed to a group of destination computers simultaneously
