The answer is sort key. A Sort Key is the column of data in a database that is used as the basis for arranging data. Iy is also used for rearranging data in the column. An Operational Database is used to collect, modify, and maintain data on a daily basis.
Answer:
(3) option is the correct answer.
Explanation:
Constructors need to initialize the object in the memory. "To declare the Constructor for any class the user needs to specify the constructor name which is already the class name". This is an object-oriented language guideline.
It is because the object is created by the name of the class and Constructor is used to allocate the memory for the object. hence Constructor is created by the name of the class.
For example--
class test //class name test
{
test() //created a constructor with class name "test"
{
}
}
In the above example class name and constructor name are same if it not then it will gives a error.
Another option is not valid for the answer to the above problem because-
- Option 1 is wrong because, for any class, the data member is a type of variable, which is used to store the data and is accessed with the help of an object.
- Option 2 is wrong because, for any class, member function is a type of user function used to accessed the variable and expressions.
- Option 4 is wrong because, package is a set used to hold classes and interfaces.
if the wide area network (wan) is supporting converged applications like voice over internet protocol (voip) internet protocol (ip) routing lookups will be even more essential to the assurance of the network.
Understanding WAN
WAN stands for Wide Area Network is a network that is used as a network that connects between local networks. Local computer networks are not only physically adjacent to each other, but share the same group of IP addresses.
The local network can be one room, one office or even one city. While the WAN itself is a network that connects these local networks within a city, province or even between countries. The difference between WAN and LAN networks is in the type of media used. Generally local networks or LANs use similar network media.
While the WAN is connected to devices with different transmission media and protocols. The WAN coverage area is also very wide, but unites the network as if it were in one room. WAN networks have lower data transfer rates than local networks or LANs. WAN network technology relies on companies providing long-distance telecommunications services. WAN networks use many kinds of network technologies with a mix of analog and digital signals for data transmission. Of course this is different from a local network or LAN which uses a connection between computers that are physically connected to each other with the same protocol and transmission media. The components in the WAN and their functions will be discussed later.
