Introduction of data cables Data cable is an important part of computer network model . From smartphone to supercomputer connections and wide range network uses and network models. It helps in network model in different types of topology models also. But we discuss what exactly called a data cable? How it is working with network model? Why these data cables are so important? In this guide, I will provide some information about the definitions, types, uses of data cables on network model with easy explanation of data cable covered topics. What is data cable? [Definition] A data cable is a wire that can transfer the data from one to another computer system. It connects to the ports available on the computer system. The user can transfer the data from one computer to another data cable connection. If two computers are connected then:- In according to data cable male port:- Port 1:- the male port of data cable is used to receive the data from the sender computer. Port 2:- th...
Let us talk about the basic detail of student in mark sheet database of student which is given in the mark sheet hard copy object. What kind of attributes and classes in according to the object oriented management system model? – Part 2
How to show the attributes and classes of the basic detail of student given in the mark sheet detail of student which is a real world object in according to the object oriented database management system model? – Part 2
The connection of the student mark sheet database, database of student and basic detail of student
Here are object of classes and attributes in the image of the relative
model of object oriented database management system.
Student mark sheet database

of the school is connected to the student because they studies at a particular
address area or campus. It holds numerical and character data type in the field
