Answer:
Let L and R be the sub-trees underneath the root r.
If the height of L (where we consider height to be the maximum length of all root-leaf paths) is ∆ more than that of R, ∆ ≥ 0, then the length of the edge (r, R) is increased by ∆.
Then, we separately perform the same cycle over L and R.
Once more, by induction, argue that this greedy algorithm is efficient –
when it does not increase the length of (r, R) edge by ∆, then prove that the solution can be improved.
Answer: True
Explanation:
Yes, the given statement is true, as the bastion host basically require two individual firewall that connect with the internal network and perimeter network by using the perimeter configuration.
Perimeter network basically isolate the the bastion host from the internal network. Bastion host is the serve as the host that connect with the external world. As, perimeter network is one of the type of the firewall network system.
Therefore, the internal network and the perimeter network basically connect with the firewall by using bastion host.
Answer:
1. The Sun is the primary source of energy that influences any planet's temperature, including Earth. The amount of energy received from the Sun is called insolation; the ratio reflected is called the albedo.
2.There are three major ways in which global warming will make changes to regional climate: melting or forming ice, changing the hydrological cycle (of evaporation and precipitation) and changing currents in the oceans and air flows in the atmosphere
3.The warming of Earth is primarily due to accumulation of heat-trapping greenhouse gases, and more than 90 percent of this trapped heat is absorbed by the oceans. As this heat is absorbed, ocean temperatures rise and water expands. This thermal expansion contributes to an increase in global sea level.
4.The main sources of greenhouse gases due to human activity are: burning fossil fuels leading to higher carbon dioxide concentrations. farming and forestry — including land use change via agriculture and livestock. cement manufacture.
5. - Reduce, Reuse, Recycle
- Use Less Heat and Air Conditioning
-Use Less Hot Water
Explanation:
The answers are as follows:
a) F(A, B, C) = A'B'C' + A'B'C + A'BC' + A'BC + AB'C' + AB'C + ABC' + ABC
= A'(B'C' + B'C + BC' + BC) + A((B'C' + B'C + BC' + BC)
= (A' + A)(B'C' + B'C + BC' + BC) = B'C' + B'C + BC' + BC
= B'(C' + C) + B(C' + C) = B' + B = 1
b) F(x1, x2, x3, ..., xn) = ∑mi has 2n/2 minterms with x1 and 2n/2 minterms
with x'1, which can be factored and removed as in (a). The remaining 2n1
product terms will have 2n-1/2 minterms with x2 and 2n-1/2 minterms
with x'2, which and be factored to remove x2 and x'2, continue this
process until the last term is left and xn + x'n = 1
Answer:
The answer is "new version of application provides more easy to use".
Explanation:
- In computer science, an application is a program, that is installed on the computer. There are many types of application software, that are "gaming software, working software, programming software, etc." At the end of time users want some new things in software to know users need programmer developed new versions of the software.
- The update usually improves the device or service in its current version, whilst an improvement is an entirely new version. Installation is usually free and easy. You also have to wait for updates that are difficult to install.
