A Remote Access Trojan (RAT) is a type of malware that allows an attacker to gain access to and control a computer or network remotely. RATs typically allow attackers to perform a variety of malicious activities, such as keystroke logging, file manipulation, and data exfiltration. RATs can be used to gain access to confidential information, launch cyberattacks on other systems, and disrupt operations. RATs are typically distributed via emails, malicious websites, and other methods.

Network architecture is the design of a communication network. It involves the physical components of a network, such as hardware and software, as well as the topology, protocols, and security measures used to connect and protect the network. Network architecture is used to define the structure of a network, including the types of nodes, their locations, and the ways in which they communicate with each other.

To delete a file in Linux, use the command line utility called rm. To delete a file, type “rm” followed by the path to the file or the file name. You can also use the -f option to force the deletion of a file without prompting for confirmation. For example, the command “rm filename” will delete the file named filename. To delete multiple files, you can use the wildcard character ‘*’ to match multiple files. For example, the command “rm *” will delete all files in the current directory.
