what is data cable? Types of cables, uses of data cables, importance of data cable explained!

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...

Discuss the student is an object and what kind of fields or attribute and classes of the student object.

How to show the attributes and classes of the student as a student is an object in according to the object oriented database management system model?

The student object with their attributes and class

Discuss the student is an object and what kind of fields or attribute and classes of the student object


The roll of the student in the school is very busy character. There are so many attributes and classes connected to the student object in the world. It makes a relation that connects with the attributes.

Name of the student

The name of the student is the attribute of the student object. There are three types of fields which are given in the ‘name of the student’ attribute.

The first name, middle name and last name are the fields that hold the character data type in the given fields.

{First name = Character data type}

{Middle name = Character data type}

{Last name = Character data type}

Class of the student

Class of the student is a class of the student object where the class is not an attribute of the student because student has categorized according to the class with their study promotion which is decided by the exams.

There are three types field in the ‘class of the student’ of the class.

Section of class is a field that includes only character data type such as {A, B, C and D}.

Subject in class is a field that includes character data type and numerical data type such as {English part 1 and 2}. It categorized by the classes in the school.

The Roll number

The roll number is an attribute of the student object. It is strong attribute if the student is in the class any subject period. It may be changed in different classes. It holds the numerical data type in the fields of the roll number.

{Roll number = Numerical data type}

The postal address and street address

The postal address is an attribute of the student object. It is also called composite attribute with street address attribute. It makes a combination of the student attribute and gets the strong connection of the address fields. It holds character and numerical data type in the field of the postal address. The postal address has a pin code to make difference between street address and postal address fields. There are some fields to compare both the attributes such as

{Plot number = Character and Numerical data type}

{Pin Code = Numerical data type}

{Street number = Numerical data type}

{Street name = Character data type}

{City = Character data type}

{State = Character data type}

The fees of the School

It is an attribute of the student object that necessary to submit the school system which is working for every student. There are four fields categorized such as exam fees, Tuition fees in school, Fees in three month and per month fees. All the fields hold the character and numerical data type in these fields.

{Exam fees = Character and numerical data type}

{Tuition fees in school = Character and numerical data type}

{Fees in three month = Character and numerical data type}

{Per month Fees = Character and numerical data type}

The admission number
