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 s...

What is a system design website? System designed website is a model of the website which is used to provide the interface of the website to provide the user interface to operate the website on the computer system. The system design model also contains the database model to manage with rule applied database through the query program or command into the integrated programming to implement the database query perform on the data when the user chooses the option such as to create the file click on the design interface option on the website to perform that operation on the database on the memory of the computer system storage device and server side is used to perform that operation on the server side scripting language program to create a file on the memory of the storage where the website database is connected to the device with the network device such as server and memory devices. Client side interface is created using some client side scripting language program that also works on the off ...

How many six types of hardware are there in the computer system? The hardware of a computer system is used to control the operating system or application software of the computer system using the given instructions to the operating system or application software to perform an action by the hardware devices to provide the output data for the end user. These hardware take input instructions as input hardware devices and provide the output data is known as output hardware devices. The hardware devices which are used to store the data, instructions, information, database, programs etc. Are known as the storage hardware devices of the computer system. Some different types of hardware devices are used for network system service provided to the computer system to share the data from one computer system to another by connecting to the IP address of the network device and computer system. Introduction to the computer system related topic and the topic is following below here: How many six types...

What is the role of the operating system on a ring topology model of a computer? Ring topology is a circular model of computer network that provide the connectivity of the computer systems and they can share the data into it circular model with the connectivity of the network device between the ring model of computer network system. The ring topology models have some types such as inside the Ring, the network are connected to each other in the form of ring and provide so many computers to connect it and able to share the data, message, information etc. In this image the ring topology model is possible through the cpu and network device combination, where every CPU is connected to the one network device that more port to connect with the cable and computer systems Where the ring model of topology have simple model aslo which contains the computer system are connected to each other using the network device in a series of ring model connectivity. That means both are connected in a single ...

How to input data is stored into the permanent memory of the computer system? The user can store the input data into the space of the storage device of the computer system. The input device is used to send the input data to the computer system and the input data is going to process on the CPU to compute their value into the output data and that output data is stored into the memory device of the computer system. In the image shows the input instructions to is process by the CPU and provide the output data to the user and the output data is command to store the data into the permanent memory. The input device sends the input instructions to the CPU and processes the value to give an output data. If the user gives a command to store the output data which is processed through the CPU then the output data can be stored in the memory space of the storage device of the computer system. Input instructions are stored in the temporary memory of the computer system and processed by the CPU. Wher...
