A network is a communication system where two or more intelligent machines or devices are physically and/or wirelessly connected together to share information.
What do you mean by intelligent machine?
Any machine capable of doing its specified work in the presence of uncertainty and variability in its surroundings. The ability of a machine to monitor its environment and alter its activities based on what it has sensed is required for intelligence. The term intelligent machine is an anthropomorphism in the sense that intelligence is defined by the criterion that the behaviours would appear intelligent if performed by a person. There is no specific, unambiguous, and widely accepted definition of intelligence.
A computer network is a system which connects two or more computing devices in order to transfer and share data. Computing equipment range from a mobile phone to a server. Physical connections, such as fibre optics, are used to connect these devices, although they can also be wireless.

Which of the following are valid IPv6 addresses?
a. fe80::64d2:bd2e:fa62:b911
b. fe80::g90p:bd2e:fa62:b911
c. fe80::64d2:bd2e::b911
d. ::1
A 128-bit IPv6 address is represented by eight 16-bit hexadecimal portions. Each section's leading zeros can be eliminated. Therefore, 141:0:0:0:15:0:0:1 and 6384:1319:7700:7631:446A:5511:8940:2552 are both legitimate IPv6 addresses.
Having numerous IPv6 addresses on one device is totally common. Every now and then, a device creates brand-new 64 bits, which it utilizes in the IPv6 address. The addresses are designated as temporary interfaces since fresh addresses are frequently produced. Eight groups of four hexadecimal numbers, each group representing 16 bits, make up an IPv6 address. Colon marks are used to divide the groups (:). A.B.C.D is the only format for a valid IP address, and A, B, C, and D must all be values between 0 and 255.

Based on the IP header data, such as the source or destination IP address, protocol, or socket number, an access control list filters traffic.
By blocking particular routing updates or controlling traffic flow, an ACL can be used to increase security. You can filter packets for a single or collection of IP addresses, as well as for other protocols like TCP or UDP, using an ACL.
The firewall runs a quick inspection on the data packets passing through the router, looking at things like the IP addresses of origin and destination, the kind of packet, the port number, and other surface-level information without actually opening the packet to look inside. Firewalls with packet filtering operate at Layer 3. These firewalls are regarded as being of the first generation.

in the osi model, what is the primary function of the network layer?
The network layer serves two primary purposes. One method is to divide segments into network packets and then reassemble the packets on the receiving end.
The other method is to route packets by determining the best path across a physical network. The data is converted into packets by the network layer. Whether the packet is a set of protocols such as IPv4 or IPv6, it is ready to fly into networks by labeling it with an address. (It still needs to go through various processes, such as data to physical, and so on.) Now that the router has shared its information, known as the routing table, with its neighbor, it is ready to communicate.

What is the OSI model?
The OSI Model also known as Open Systems Interconnection Model, is a framework used to describe the functions of a networking system.
In the physical layer, the lowest OSI layer the sent packets is transmitted across the physical layer of the sending device to the physical layer of the receiving device.
In the data link layer, nodes connected directly are used to perform node-to-node data transfer where the sent packets are packaged into frames. Errors that might have occurred in the physical layer is corrected in the data link layer.
In the network layer, the frames from the data link layer are received, and prepared for delivery to their intended destination among based on the addresses contained inside the frame which in this case is Host B.
In the transport layer, the delivery and error checking of packets takes place. This layer regulates the size, sequencing, and ultimately the transfer of data between systems and host.
In the session layer, A control of the conversations between different computers takes place.
In the presentation layer, formating or translating of data for the application layer based on the syntax or semantics that the application accepts is done.
