Answer:
Select commands would return all the rows and columns in the table.
Explanation:
In the database management system, it consists of one or more table. To handle this table it provides the concept of SQL(Structured Query Language). It is a programming language that design, manage, store data into the relational database. It is case sensitive language. In the SQL many commands used for handle table data, it returns all rows and columns from the table.
Syntax of select command can be given as:
Select * from tablename;
Example:
select * from ProductCategory;
returns all the data from the table.
In select command, we will also return select data by using condition
SELECT column1 [, column2, ...]
FROM tablename
WHERE condition
In the conditional clause we use these operators that can be given as:
= Equal, > Greater than, < Less than, >= Greater than equal to, <= Less than equal to, != Not equal to.
A proxy server. A system requests information from the internet, and that traffic is routed through the proxy server before arriving to the requesting system.
This is why proxy servers are used for hiding identity and being more secure, as internet traffic would show the IP address of the proxy server, and not the requesting system, though this often depends on the type of proxy server, as some proxy server's main objective isn't anonymousity, but rather efficiency.
Answer:
Following are the answer to this question.
Explanation:
It is a mechanism, that is also known as EUI-64, which enables you an automatic generation of its specific host ID. It using the device on the 48-bit MAC address, which helps to construct the special 64-bit host ID. It also helps you to build a DHCP-type IPv6 network, that's why we can say that the above-given standard is widely used to create a 64-bit host ID on IPv6 servers.
An application where you would prefer a parallel circuit over series would be a string of Christmas lights. If the light string is wired in parallel, when one bulb burns out, it would not effect the red of the string.
Answer:
Explanation:
Since all of the items in the array would be integers sorting them would not be a problem regardless of the difference in integers. O(n) time would be impossible unless the array is already sorted, otherwise, the best runtime we can hope for would be such a method like the one below with a runtime of O(n^2)
static void sortingMethod(int arr[], int n)
{
int x, y, temp;
boolean swapped;
for (x = 0; x < n - 1; x++)
{
swapped = false;
for (y = 0; y < n - x - 1; y++)
{
if (arr[y] > arr[y + 1])
{
temp = arr[y];
arr[y] = arr[y + 1];
arr[y + 1] = temp;
swapped = true;
}
}
if (swapped == false)
break;
}
}
