Answer:
Check the explanation
Explanation:
A packet filter firewall is used as a check point between internal corporate network to the outside internet. It blocks all the inbound traffic from the outside hosts trying to initiate a direct TCP connection to the internal corporate webserver. The network design with firewall is shown in the attached image below:
The figures in the attached image below shows an internal corporate network is protected with a packet filter firewall to minimize the inbound traffic from the external network or an internet. Therefore, the packet filter is used as a check point between the network.
The packet filter blocks all attempts by the outside hosts in order to initiate a direct TCP connection to the internal webserver of the internal corporate network.
Going by the second part of the attached image below can can therefore conclude that:
• Rule 1 specifies that, deny any packet with the destination address 5.6.7.8 if the STN flag of TCP header is set.
• Rule 2 specifies that, allow the inbound email traffic from the external source.
• Rule 3 specifies, allows the Outbound TCP traffic from the internal corporate network.
• Rule 4 specifies, allows outbound Email traffic from the internal corporate network to the external network.
• Rule 5 specifies, block any traffic from any source to the any destination.
Hello,
Well my advice for Sara when using the web would be 3 things.
1: Never tell anyone where you live,Your name, Or any other personal information.
This is important as it will keep you safe and others that are in your family.
2: Get anti virus hardware on your devise.
This will help to stop bad people, and bugs/glitches,this will also protect you from information thieves.
3: Make sure to keep your passwords saved on paper.
I know a lot of people use, google(ect.) to save there passwords to make everything easy, but a good way to never loss them is to wright them down.
Have a great day!
Answer:
loop
Explanation:
Loop is the one which is used to execute the specific statement again and again until the condition is true.
In the programming, there are 3 basic loop used.
1. for loop
<u>Syntax:</u>
for(initialization, condition, increment/decrement)
{
statement;
}
the above statement execute until the condition in the for loop true when it goes to false, the loop will terminate.
2. while loop
<u>Syntax:</u>
initialization;
while(condition)
{
statement;
increment/decrement;
}
it is work same as for loop and the increment/decrement can be write after or before the statement.
3. do while
syntax:
initialization;
do
{
statement;
increment/decrement;
}while(condition);
here, the statement execute first then, it check the condition is true or not.
so, if the condition is false it execute the statement one time. this is different with other loops.
Answer:
Swap daemon
Explanation:
Swap daemon manages the physical memory by moving process from physical memory to swap space when more physical memory is needed. The main function of the swap daemon is to monitor processes running on a computer to determine whether or not it requires to be swapped.
The physical memory of a computer system is known as random access memory (RAM).
A random access memory (RAM) can be defined as the internal hardware memory which allows data to be read and written (changed) in a computer.Basically, a random access memory (RAM) is used for temporarily storing data such as software programs, operating system (OS),machine code and working data (data in current use) so that they are easily and rapidly accessible to the central processing unit (CPU).
Additionally, RAM is a volatile memory because any data stored in it would be lost or erased once the computer is turned off. Thus, it can only retain data while the computer is turned on and as such is considered to be a short-term memory.
There are two (2) main types of random access memory (RAM) and these are;
1. Static Random Access Memory (SRAM).
2. Dynamic Random Access Memory (DRAM).
