Answer: True
Explanation:
TCP is the transmission control protocol which and TCP ACK is the transmission control handshake method which are used by TCP. It basically indicates the next sequence number in the method when the flag is set.
Firstly, the ACK (Acknowledge) send by the each end for the initial sequence number itself but it does not contained any type of data. In the TCP segment header ACK contain 32 bit field.
The acknowledgement is just a proof to clients that ACK is a specific to the SYN when the clients initiate.
Answer:
Input, Processing, Storage, Output and Communication devices.
Explanation:
Input devices of computer are like Keyboard, Mouse, Scanner. Output devices of a computer are printers, monitors, and headphones.
There are two storages of computer one of them is REM, which can be lost if computer shutdown/closes. Data stays written on the disk until it's erased or until the storage medium fails (more on that later). An example of a communication device is the microphone.

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.
