What is the main purpose of a firewall on a computer?
The main purpose of a firewall on a computer means to protect the data, instructions, information, database, files, programs etc. Which are used for tasks performed on a computer system to provide the output data to the end user.
The computer system is used to store the files of the operating system, application software and user database files. These types of files are used to protect from the other user or unknown user or attackers from the internet, because they can access these types of files which is beneficial for those unknown users.
They can steal from the internet service with unprotected internet connection from the security layer using malicious files such as virus files, malwares, worms etc.
Here the firewall is used to protect the database from the malicious files transmission into the computer system memory storage device and without scanning the system the downloaded files are not permitted to save into the computer system database in the memory device.
Introduction to the computer system related topic and the topic is following below here:
What is the main purpose of a firewall on a computer?
Let's discuss the computer system related topic is mentioned above and the explained following below here:
In this topic you can learn about the firewall on the computer system. The firewall is an operating system feature that provides the protection of the data, information, user database, application database, operating system database, programs, flat files, relational files, object based files etc. These files are saved in the memory of the storage devices of the computer system and protected by the firewall of the operating system, such as scanning features of all types of files, and detecting the malicious files from the storage device of the computer system. The malicious files are used to corrupt the other files in the memory device of the computer system that has also installed the operating system and some application software, also the user database. These corrupted files are ready for transmission from the computer system of the user to steal the information of the user and related database for sending to black market.

There are some points on the computer system and computer security related to the topic of "What is the main purpose of a firewall on a computer?" following below here:

| In the image shows the firewall of the computer system and the features of the operating system to protect the database from the malicious files |
- Firewall is a wall to secure the data of the computer system
- Firewall is a layer of security on the particular operating system as a feature
- Firewall detects the malicious files from the computer system
- Firewall warns to the user to transmit the data from one device to another
Let's discuss the points listed above about the computer system and security of computer systems related to the topic of "What is the main purpose of a firewall on a computer?" explanation following below here:
Firewall is a wall to secure the data of the computer system
Firewall is a wall to secure the data of the user on the computer system when they activate the firewall feature of the operating system because the operating system has a feature to secure the data of the storage device that is connected to the motherboard installed into the cpu cabinet of the computer system.
The firewall is used to protect the data by detecting the threats and malicious files or infected files by the malicious files or dangerous files that have been inserted into the storage device of the computer system.
These infected files or malicious files can harm the whole database of the user as a personal or official database which is useful for the user.
This data can be protected by scanning the system of the firewall after activation or it is already activated in the operating system during the package period of the operating system using the laptop or desktop computer system.
When the user commands to scan the files that are stored in the storage device of the computer system then the firewall can scan and detect the malicious files from the storage device and provide the options to delete or permanently remove the infected files and malicious files on the storage device of the computer system.
Firewall is a layer of security on the particular operating system as a feature
Firewall is a layer of the security on the particular operating system because the security layer of the operating system protects the database of the operating system and the user who saves the data into the storage device of the computer system.
The firewall contains so many option and service such as scanning all files, depleting files which has infected from the malicious files or malicious application software, protect the internet browser and make a safe practice on the internet etc are the options that protects the user activities and other types of the data which has user to download on the storage device of the computer system.
The firewall is a security layer of the computer system that the features of the operating system to protect the database of the user and operating system and als protects the device or computer system indirectly because if the operating system database protected then the viruses or malicious files cannot be able to harm the devices of the computer or whole computer system.
Firewall detects the malicious files from the computer system
Firewall detects the malicious files from the computer system that means the malicious files contains an extension that the malicious can convert the other files which have stored into the space of the memory of the permanent storage device.
The file which is infected and converted into the same extension can also be a malicious files to share the data to the server of the cybercriminals who have developed the malicious files and inserted into the database of the computer system which doesn't have any security features of the operating system such as firewall of the operating system to protect the database of the user and operating system also official database which is useful for the cybercriminals.
The firewall can detect these malicious files and protect all types of data which has been converted and can also be detected by the firewall security layer of the operating system.
The firewall can also protect the data during the transmission in the network system and other types of transmission such as through the usb detachable storage device can connect to the computer system.
Firewall warns to the user to transmit the data from one device to another
Firewall warns the user to transmit the data from one device to another. That means the firewall to the user to transmit the wrong data or infected data files can be dangerous for the other file such as viruses, threats and malware etc. Are the types of the malicious files on the computer system database to corrupt the files for sharing and transmission to the network of the cybercriminals.
The user connects the device such as flash drive device can store upto 1 gb to 1 tb of storage data according to their capacity of the pen drive or flash drive.
The firewall can warn the user to scan before the copy of the data from the pen drive or flash drive connected to the CPU cabinet.
The firewall also protects and scans the device data which is connected to the computer system such as flash drive or pen drive.
The firewall can save the data of the user which has a value in the flash drive storage device of the computer system connecting it.
The firewall scans all the files which are saved into the drives which are additionally connected to the computer system to scan it and delete the infected files or blocks those files and cannot allow the permission to transmit from storage device to the computer system storage device.
