Li-Fi vs Wi-Fi: A Battle of Light and Waves Li-fi is a light fidelity device that supports only the infrared and other lighting systems to transfer the data to the device which is used to receive from the sender device. Wifi is a wireless fidelity device that supports the radio waves to transfer the data to the wifi device which is used to receive the wifi signals at the limited ranges due to the device version capacity.

What is database security and integrity?
There are some points on the computer system and database technology related topic of "What is database security and integrity?" following below here:
The database security
- The database security is a method to protect the database from the cybercriminals
- The database security is used to develop to protect from the unknown user access
The integrity of the database
- Is a part of the database to where the accuracy is applied on the field of the record or tuples
- The database records can be a consistency applied on the field of the record
Let's discuss these points listed above about the computer system and database technology related topic of "What is database security and integrity?" explanation following below here:
The database security
The database security is a method to protect the database from the cybercriminals
The database security includes the layer of protecting the database file from the security interface over the database applications which is used to access the database file such as login system, third party application or website to access and connect the account identification of a particular user on the database application software through the link sent on the website portal as a email, message, OTP code etc.
The database secured from the secret question to access the database file from the database application software. Such as suggested by the database applications software the security key to access the database and downloaded into the particular user application software storage or any types of storage device. The database is secured from many types of security systems that are applied on the database applications software which is used to access the file which is stored into the memory storage device of the computer system. If the database has not any types of security then the database is accessed by the cybercriminals for their profit.
The database security is used to develop to protect from the unknown user access
The database security is used to develop to protect from the unknown user who can access the valuable database of the organisation without any security through the computer system.
The unknown user accesses the database when they know about the valuable database for profit. Such as the model which has a value on the market at high rates for selling. So the unknown user can steal the database model through the access if the database security is not applied on the database files to access. The security of the database is highly recommended because today the cybercriminals are ready to steal the information about the user and organization database to access and earn profit after using the database as the misuse.
The integrity of the database
Is a part of the database to where the accuracy is applied on the field of the record or tuples
The accuracy of the database is necessary to apply on the records and attributes of the database of a particular subject or object. The accuracy is used to apply on the fields of the records because most of the records have wrong value in their fields or not stored proper value in the decimal or other format of digits.
Such as some users storing the data into the fields of the pin number instead of the mobile field or attributes of the particular person record. Then the pin number fields applied the formula to make accuracy of the data and apply the limitation of the 4-5 only digits only can store in this field. That means the record of the pin number field is fully filled from the 4 or 5 digits of pin number can enter into the field or attribute.
Similarly mobile number validation applied to enter only ten or 10 digits number of phone of a person contact of mobile number.
The database records can be a consistency applied on the field of the record
The database records can be a consistency applied on the field of the record that means the data of the attributes of the particular record of person, object or subject contains description, address with complete as divided into the number fields or character fields included on the database of all records.
Such as the person having a contact number of a landline or mobile device number and the fields required to enter only the digits value on the particular attributes of the contact number of the person. If the user enters the character value in the field of the contact then the message displays to the user this requires entering only the contact number because consistency applied the rule of the types of data value into the attribute of the record.
