I would say 3-D model!!!! not 100% sure but this sounds most correct!
Answer: Column F
Explanation: In Microsoft excel, for the sake of robustness and to aid the effectiveness of updating formulas across cells. The reference of cells are treated as relative which means that when formulas are copied across columns or within rows, they get updated automatically. However, some numbers may be treated as constants such that we do not want them to change or be updated as we move acisss cells. Thus, such numbers are treated Given absolute references, which is made possible by adding a '$' prefix before the colum alphabet or row number or both. in the scenario given above, the row has the $ prefix, hence, it is absolute and will not change but the column alphabet does not and hence, treated as relative.
Answer:
Following are the difference to this question:
Explanation:
IPv4:
The 
is uses the packet changed method, that is a Link Layer networks(like Ethernet). It has 4.3 billion addresses capacity. It uses the 32-bit logical device address, that written in decimal language.
It is divided by 4 bytes E.g. 192.168.1.1
The host part and network part are 2 parts. For a network, the host part may vary, while for the entire subnet, the network part remains equal.
The scheme of 232 addresses is available on application depends on security.
IPv6:
The IPv6 is used in the internet protocoland it is higher than IPv4. It can provide endless number Opf addresses, and use to solves the problem of IPv4 exhaustion and satisfies the demand for rising networking.
IPv4 Substitutor Built to meet more IP address requirements. In the Logical address of 128-bit Written hexadecimally and with colons divided, and the Space of 128 addresses are required. IPsec is an integrated security feature.
Without a/an Operating system. a computer is useless
