Discuss the role of resources on operating systems on computers? The Resources of a computer can be input devices, output devices, storage devices, etc. which are functional from the operating system to perform a task on the computer for the user. A computer resource performs a task such as:- a scanner is an input device to perform a task on the computer to give input image database file to the memory of computer to store it by default settings of driver software and the image file can be used for editing work and other users to send it for their personal or official uses. Resources in operating systems (OS) play a crucial role in managing computer hardware and software components. These resources include CPU, memory (RAM), storage devices, input/output (I/O) devices, and network connections. The OS acts as a resource manager, allocating and deallocating resources to running programs, ensuring efficient utilization and preventing conflicts. By managing resources, the OS enables multipl...

Explain the multiple tasking in the operating system? The multiple task means the operating system runs many programs or applications on the computer parallel to provide flexibility of using the computer on their operating system environment to user services such as:- a game playing for entertainment with listening music through another application software or music player. The user can prepare a document offline and work on it currently for sending the email to their head employee as the head officer giving instructions for creating the content in the document file and sending the document file at same time through browser application links website to email to the head officer. Multitasking in an operating system allows multiple processes or threads to run concurrently, improving system efficiency and responsiveness. The OS allocates specific time slices (called time quanta) to each process, switching between them rapidly to create the illusion of simultaneous execution. This context ...

Importance of cybersecurity on the internet world Cybersecurity is a technique that protects the users database on their device and some applied rules or protocols for the user that are not allowed in their country to access the specific databases or content or links of websites. The user can protect their database on the internet through the cloud service to store the database into the secured website that provides the stored database and higher security features such as:- Multi Factor authentication, or two factor authentication on the security model. In today's digital age, cybersecurity plays a vital role in protecting individuals, organizations, and governments from an ever-evolving landscape of cyber threats. As our reliance on the internet and digital technologies grows, so does the risk of cyber attacks, data breaches, and identity theft. Effective cybersecurity measures help safeguard sensitive information, prevent financial losses, and maintain trust in online transaction...

How to Protect Your Computer from Viruses? The viruses are the most dangerous program that corrupt the database of the computer system and the user's database and valuable information also. The user needs to be aware of these types of viruses to protect your computer and database using antivirus software, be aware to access only secure links, misbehave of user interface or slow without any reasons etc. These factors protect the data from viruses after removing the viruses and malicious file or software on the computer system. To protect your computer from viruses, install reputable antivirus software and keep it up-to-date to detect and remove malware. Avoid opening suspicious emails, attachments, or links from unknown sources, as they may contain viruses. Regularly update your operating system and applications to patch security vulnerabilities. Use strong passwords and enable firewall protection to block unauthorized access. Be cautious when downloading software or files from the ...

Describe the Role of encryption and access control in data protection? The role of encryption is a method to protect the data in the data communication system during the data transmission between two or more devices or computers also. The encryption method is converting the data in a specific format of data which is encoded and then decoded from the same application software which is used to encode the data in the ciphertext. The ciphertext is a special format of data which is used to transfer between devices and unknown users cannot access this format and doesn't understand also to make meaningful information in the data transmission of data packets in the data communication system. Access control is a security layer applied over the user account generally used during the development of application software or web application or website etc. to provide the security to check the user credentials in the login form. Encryption and access control play crucial roles in data protection....
