A router has only two links; incoming link has bandwidth 4 Mbps and outgoing link has bandwidth 16 Mbps. The next hop router in the outgoing link is 100 km away. A packet of 8000 bytes arrives at the incoming link. Calculate the time interval between the time when the first bit of the packet enters the router incoming interface and the time when the first bit of the packet enters the next hop router incoming interface. Initially all the queues are empty.
Answers
The time interval between the first bit entering the router's incoming interface and the first bit entering the next hop router's incoming interface is approximately 16.333 milliseconds.
To calculate the time interval between the first bit of the packet entering the router's incoming interface and the first bit entering the next hop router's incoming interface, we need to consider the bandwidth, distance, and packet size.
Given information:
Incoming link bandwidth: 4 Mbps
Outgoing link bandwidth: 16 Mbps
Next hop router distance: 100 km
Packet size: 8000 bytes
First, let's calculate the transmission time for the packet on the incoming link:
Packet size in bits: 8000 bytes * 8 bits/byte = 64,000 bits
Transmission time = Packet size / Incoming link bandwidth
Transmission time = 64,000 bits / 4 Mbps = 16 ms
Next, let's calculate the propagation delay for the distance to the next hop router:
Propagation speed: Assuming the propagation speed is approximately the speed of light (3 x 10^8 m/s)
Propagation delay = Distance / Propagation speed
Distance: 100 km = 100,000 m
Propagation delay = 100,000 m / (3 x 10^8 m/s) = 0.333 ms
Finally, the time interval between the first bit entering the router's incoming interface and the first bit entering the next hop router's incoming interface is the sum of the transmission time and propagation delay:
Time interval = Transmission time + Propagation delay
Time interval = 16 ms + 0.333 ms = 16.333 ms
Therefore, the time interval between the first bit entering the router's incoming interface and the first bit entering the next hop router's incoming interface is approximately 16.333 milliseconds.

Answer:
Explanation:
the molecules to slow down and they get closer to together.
:)
Convection happens in fluids (liquids & gases). The heat energy moves through the material as the particles in the material move through the material.
Hot liquids and gases rise because when they are heated they expand and become less dense. The less dense warm liquid or gas then floats up through the more dense cold liquids and gases.
Cold liquids and gases sink because when cooled they contract and become more dense. The more dense cold liquids and gases sink down through the less dense warm liquids and gases.
These changes in density cause the convection currents in the liquid or gas.

Select the best analysis for this scenario from the list below:
A. In some circumstances this may help, especially if the missing key is frequently search for.
B. An external cache will always speed up the search for previously failed searches, but only if an array-based implementation is used.

D. This is always a bad idea.
Answers
The option A is the correct answer.Option A is the best analysis for this scenario from the list below. Here's why:Explanation:The binary search algorithm is used to find a particular key in a sorted array. In the case of a failed search, it takes log2 n comparisons to determine that the key is not present in the array.
If the application frequently searches for the missing key, the time required to access the array can be reduced by storing recent unsuccessful searches in a cache or store.In certain scenarios, such as when the absent key is often looked for, this might help.
An unsorted linked-list can be used to implement the cache. In such a case, the linked-list implementation of the cache provides a way to access the first item in O(1) steps. It is preferable to keep an external cache. However, it will only speed up previously unsuccessful searches if an array-based implementation is employed.

hy does payments constitute such a large fraction of the FinTech industry? (b) Many FinTech firms have succeeded by providing financial services with superior user interfaces than the software provided by incumbents. Why has this strategy worked so well? (c) What factors would you consider when determining whether an area of FinTech is likely to tend towards uncompetitive market structures, such as monopoly or oligopoly?
Answers
(a) lengthy and complex processes for making payments (b) legacy systems and complex interfaces (c) regulatory requirements and substantial initial investment, can limit competition
(a) Payments constitute a significant portion of the FinTech industry due to several factors. First, traditional banking systems often involve lengthy and complex processes for making payments, leading to inefficiencies and higher costs. FinTech firms leverage technology and innovative solutions to streamline payment processes, providing faster, more secure, and convenient payment options to individuals and businesses. Additionally, the rise of e-commerce and digital transactions has increased the demand for digital payment solutions, creating a fertile ground for FinTech companies to cater to this growing market. The ability to offer competitive pricing, improved accessibility, and enhanced user experience has further fueled the growth of FinTech payment solutions.
(b) FinTech firms have succeeded by providing financial services with superior user interfaces compared to incumbents for several reasons. Firstly, traditional financial institutions often have legacy systems and complex interfaces that can be challenging for users to navigate. FinTech companies capitalize on this opportunity by designing user-friendly interfaces that are intuitive, visually appealing, and provide a seamless user experience. By prioritizing simplicity, convenience, and accessibility, FinTech firms attract and retain customers who value efficiency and ease of use. Moreover, FinTech companies leverage technological advancements such as mobile applications and digital platforms, allowing users to access financial services anytime, anywhere, further enhancing the user experience.
(c) Several factors contribute to the likelihood of an area of FinTech tending towards uncompetitive market structures such as monopoly or oligopoly. Firstly, high barriers to entry, including regulatory requirements and substantial initial investment, can limit competition, allowing a few dominant players to establish market control. Additionally, network effects play a significant role, where the value of a FinTech service increases as more users adopt it, creating a competitive advantage for early entrants and making it challenging for new players to gain traction. Moreover, data access and control can also contribute to market concentration, as companies with vast amounts of user data can leverage it to improve their services and create barriers for potential competitors. Lastly, the presence of strong brand recognition and customer loyalty towards established FinTech firms can further solidify their market position, making it difficult for new entrants to gain market share.
