Answer:
the first step Peter must take is to configure the default policies for each of the built-in chains to ACCEPT.
He can do this by running the following:
$ sudo iptables -P INPUT ACCEPT
$ sudo iptables -P FORWARD ACCEPT
$ sudo iptables -P OUTPUT ACCEPT
Explanation:
If he doesn't do this, he stands the risk of being locked out of the server through the SSH.
Having done the above, he can proceed to run the following commands:
$ sudo iptables -t nat -F
$ sudo iptables -t mangle -F
$ sudo iptables -F
$ sudo iptables -X
The above will effectively flush (-F), and delete all non-default chains (-X).

Explanation:
it acts as a barrier between a trusted system or network and outside connections, such as the Internet. However, a computer firewall is more of a filter than a wall, allowing trusted data to flow through it. ... For example, a basic firewall may allow traffic from all IP.
if my answer helps you than mark me as brainliest.
Answer:
hope this helps
Explanation:
Firewalls are software or hardware that work as a filtration system for the data attempting to enter your computer or network. Firewalls scan packets for malicious code or attack vectors that have already been identified as established threats.And also firewall is a network security device that monitors incoming and outgoing network traffic and permits or blocks data packets based on a set of security rules.

In the Gradient Descent algorithm, we are more likely to reach the global minimum, if the learning rate is selected to be a large value.
a. True
b. False
Answer:
false i think.
Explanation:
Gradient Descent is more likely to reach a local minima. because starting at different points and just in general having a different starting point, will lead us to a different local minimum( aka the lowest point closest to the starting point). if alpha(the learning rate) is too large, gradient descent may fail to converge and may even diverge.

During the data transmission there are chances that the data bits in the frame might get corrupted. This will require the sender to re-transmit the frame and hence it will increase the re-transmission overhead. By considering the scenarios given below, you have to choose whether the packets should be encapsulated in a single frame or multiple frames in order to minimize the re-transmission overhead.
Justify your answer with one valid reason for both the scenarios given below.
Scenario A: Suppose you are using a network which is very prone to errors.
Scenario B: Suppose you are using a network with high reliability and accuracy.
The packets would be encapsulated in single frame in scenario A. In scenario B, it should be in multi frames.
In scenario A, given that this network has been said to be prone to error, the packets should be encapsulated in single frames.
The reason for this is because, using a single frame helps to decrease error. We have been told already that it is prone to error. If you use the multi frame, there would be very high likelihood of errors occurring.
In scenario B, given that the network is accurate and very reliable, the best packet is the multi frame.
It would give a quicker transmission and the likelihood of errors occurring is also low.

You have n warehouses and n shops. At each warehouse, a truck is loaded with enough goods to supply one shop. There are m roads, each going from a warehouse to a shop, and driving along the ith road takes d i hours, where d i is an integer. Design a polynomial time algorithm to send the trucks to the shops, minimising the time until all shops are supplied.
Following are the steps of the polynomial-time algorithm:
Split the routes according to their categorizationAssuming that mid = di of the middle road, low = road with the least di, and high = road with the highest di, we may do a binary search on the sorted list.All shops must be approachable only using these roads for every road, from low to mid.Check if all shops can be reached from[tex]\bold{ low \ to\ mid+1}[/tex] using only these roads.There is a solution if every shop can be reached by road only up to [tex]\bold{mid+1}[/tex], but not up to mid.You can [tex]\bold{set \ low = mid+1}[/tex] if all businesses aren't accessible using both [tex]\bold{mid\ and\ mid+1}[/tex] roads.If every shop could be reached using both mid and mid+1, then set high to mid-1.With these layouts of businesses and roads, no response can be given because [tex]\bold{ low > high}[/tex]You can do this by [tex]\bold{set\ mid = \frac{(low + high)}{2}}[/tex]The new low, mid, and high numbers are used in step (a).In a minimum amount of time, this algorithm will determine the best strategy to supply all shops.

Suppose we have 999 records of employees Emp1, Emp2, Emp5, Emp6 and so on up to Emp998 and Emp999 stored in a sequence. Hence, records are nothing but a row in the table. In the employee table, we want to insert new records Emp3 and Emp4 in the sequence, and once we have done insertion we need to update and retrieve the record efficiently to optimize the performance of a database by minimizing the access time when query is being executed.
You are required to solve the problem with the index sequential access method with pros and cons in the given scenario
The records in the table represents the employee ID of each employee. Assume the table name is EMPLOYEES and the field name of employee IDs is ID, the following SQL query inserts Emp3 and Emp4 into the employees table.
INSERT INTO EMPLOYEES (ID) values (Emp3), (Emp4)
The advantage of using ISAM is that priorities are given to the indices of the records being inserted. So, Emp3 and Emp4 will be inserted immediately after Emp2.
However, a major disadvantage of using ISAM is that it is very expensive to keep the indices in a sequential order;
