The command to prevent the shell from using too much of the system's resources is: ulimit -t <time limit>. This command sets a time limit for the shell to run. After the time limit is reached, the shell will stop running and will not take up any additional system resources.
The Benefits of Utilizing the ulimit CommandThe ulimit command is a powerful tool for managing the resources a shell can consume. By setting a time limit for a shell to run, the ulimit command can help prevent the shell from using too much of the system's resources. This can be beneficial in a variety of ways.
First, setting a time limit for the shell helps ensure that other applications running on the system are not impacted by the shell's resource usage. If the shell is allowed to run indefinitely, it could hog resources that are needed by other applications. This can lead to performance issues, as the shell will be taking up resources that could have been used by other applications. By setting a time limit, the shell will not be able to take up more resources than necessary, and other applications will be able to run smoothly.
Second, the ulimit command can help improve system security. If the shell is allowed to run indefinitely, it could be used by malicious users to launch attacks against the system. By setting a time limit for the shell, malicious users will not be able to use the shell for extended periods of time, which can help protect the system from potential attacks.

This guarantees that packets are coming from a reliable source and not an intruder Encryption. Each packet's IP header and payload are both encrypted via IPsec.
What is IP Security?
A system called IP Security, or IPsec, allows for the safe transmission of data over open networks. to create circuits utilising IPsec tunnelling, where all data transported between the two endpoints is encrypted, to secure network data. With the following qualities, IPsec can secure our traffic. Confidentiality is ensured by encrypting our data so that only the sender and recipient may access it. Establishing secure connections between devices is a VPN operates. The IPsec or SSL/TLS encryption protocols are frequently used in VPNs.

assuming a packet loss is detected after the 26th round by a receipt of a triple duplicate ack, the value of the congestion window size will be
The threshold will be set to half the current value of the congestion window (8) when the loss occurred and congestion window will be set to the new threshold value + 3 MSS. Thus the new values of the threshold and window will be 4 and 7 respectively.
What is Congestion window?
The congestion window (CWND) is one of the factors in TCP that determines the maximum number of bytes that can be sent out at any given time. The sender maintains the congestion window, which prevents a link between the sender and the receiver from becoming overloaded with traffic. This is not to be confused with the sender's sliding window, which exists to keep the receiver from becoming overloaded. The congestion window is calculated by estimating the amount of congestion on the link.
When a connection is established, the congestion window, which is kept independently by each host, is set to a small multiple of the maximum segment size (MSS) allowed on that connection.
