The answer a identifying portfolio goal
Line graphs can also be used to compare changes over the same period of time for more than one group. Pie charts are best to use when you are trying to compare parts of a whole. They do not show changes over time. Bar graphs are used to compare things between different groups or to track changes over time.
Answer:
a. 118.20.210.254
Explanation:
Here are the few characteristics of Class A:
First bit of the first octet of class A is 0.
This class has 8 bits for network and 24 bits for hosts.
The default sub-net mask for class A IP address is 255.0.0.0
Lets see if the first bit of first octet of 118.20.210.254 address is 0.
118 in binary (8 bits) can be represented as : 1110110
To complete 8 bits add a 0 to the left.
01110110
First bit of the first octet of class A is 0 So this is class A address.
For option b the first octet is : 183 in the form of bits = 10110111 So it is not class A address
For option c the first octet is 215 in the form of bits = 11010111 So it is not class A address
For option d the first octet is 255 in the form of bits = 11111111. The first bit of first octet is not 0 so it is also not class A address.
Answer:
Sure. In Unit test 5, it's looking for 1 instead of 0. You are returning 0 instead of 1.
0 requires 1 digit to express it and should therefore return 1.
In line 6, change the 0 to a 1.
Answer:
NAT
Proxy
IPv6
Explanation:
Network Address Translation (NAT) allows a local area network (LAN) to connect to the internet using only one external IP address. The LAN addresses (typically 192.168.x.x) can be used over and over again.
A proxy is a computer that makes requests to the internet on behalf of the computers on a LAN. It is a more restricted flavour compared to the NAT, but the effect is the same.
IPv6 is a new addressing scheme that will use a 48 bits address space rather than a 32 bits address space of IPv6, and that would provide plenty of addresses.
