Answer:
subnet mask
Explanation:
A subnetwork or subnet mask is a logical subdivision of an IP network.
To find out your subnet mask, the simlest way around it is to is to run a simple command line in windows.
Simply press the Windows key and “R” at the same time to open the command prompt and type “cmd” followed by “enter.” This will allow you to see your subnet mask.
In IPv4, the subnet mask 255.255. 255.0 is 32 bits and consists of four 8-bit octets. The address: 10.10. 10.0 subnet mask 255.255.255.0 this simply indicated that the subnet mask consists of a range of IP addresses from 10.10.10.0 - 10.10.10.255.
Subnet masks (IPv4) are often involved in identifying the range of IP addresses that make up a subnet, it can also be described as a group of IP addresses on the same network.
Explanation:
Both Primary Key and Candidate Key are the attributes that are used to access tuples from a table. These (Primary key and Candidate key) are also can be used to create a relationship between two tables.
- A Candidate Key can be any column or a combination of columns that can qualify as a unique key in the database. Each Candidate Key can qualify as a Primary Key.
- A Primary Key is a column or a combination of columns that uniquely identify a record. The primary key is a minimal super key, so there is one and only one primary key in any relationship.
<em> The main difference between them is that a primary key is unique but there can be many candidate keys. </em>
I hope you find this information useful and interesting! Good luck!
Answer:
The answer is "Option A".
Explanation:
The program to the given question can be given as:
program:
var1 = "Happy" #defining variable var1
var2= "Birthday" #defining variable var2
var3 = (var1+var2) *2 #defining variable var3 and calculate value
print (var3) #print value.
Output:
HappyBirthdayHappyBirthday
In the above python program, three variable is defined, that is var1, var2, and var3, in which variable var1 and var2 we assign a value, that is "Happy" and "Birthday".
In variable var3 we add the value of var1 and var2 variable and multiply by 2. It will print the variable value two times. and other options are not correct that can be defined as:
- In option B and C, Both variable var1 and var2 print there values two times but in option B var1 value print two time and var2 value print one time only and option C var1 variable value is print only one time and var2 variable value is print two times that's why it is not correct.
- In option C, Both variable var1 and var2 print there values two times that's why it is not correct.
