This data replicates such that it is identical everywhere. Engineers find that some replicas are updating slowly.
The practice of replicating data involves storing the same information in many places in order to increase data accessibility and availability as well as system resilience and dependability.
Data replication is frequently used for disaster recovery to guarantee that an accurate backup is always available in the event of an emergency, hardware failure, or system breach where data is compromised.
Data access can be accelerated by having a replica, especially in businesses with numerous locations. When accessing data from North American data centers, users in Asia or Europe could experience latency. Access times can be sped up and the burden on the network balanced system by placing a copy of the data close to the user.
Additionally, replicated data can optimize and enhance server speed.

What is mobile app?
A mobile application, sometimes known as an app, is a computer programme or software application that is meant to run on a mobile device such as a phone, tablet, or watch. Mobile applications are frequently distinguished from desktop programmes, which are intended to operate on desktop computers, and web applications, which are intended to run via mobile web browsers rather than directly on the mobile device. Apps were originally intended for productivity aids such as email, calendar, and contact databases, but public demand for apps resulted in rapid expansion into other areas such as mobile games, factory automation, GPS and location-based services, order-tracking, and ticket purchases, resulting in millions of apps now available. Many apps necessitate Internet access.
Azure Cognitive Services are APIs, SDKs, and services that enable developers to create intelligent apps without prior AI or data science training.

host a and b are directly connected with a 100 mbps link. there is one tcp connection between the two hosts, and host a is sending to host b an enormous file over this connection. host a can send its application data into its tcp socket at a rate as high as 120 mbps but host b fills up its buffer at a rate of 40mbps. on average, what is the long-term rate at which host a sends data to host b?
The long-term rate host a sends data to host b is 100 Mbps, Host A's sending rate can be at most 100 Mbps. Still, Host A sends data into the receive buffer faster than Host B can remove the data.
Transmission Control Protocol (TCP) means a standard that describes how to establish and maintain a network conversation by which applications can exchange data. TCP works with the Internet Protocol (IP), which describes how computers send packets of data to each other.
Based on the story above, the receive buffer fills up at a rate of roughly 40 Mbps. If the buffer is full, Host B signals to Host A to stop addressing data by setting RcvWindow = 0; Host A then stops addressing until it receives a TCP segment with RcvWindow > 0. Host A will start sending as a function of the RcvWindow values it receives from Host B and also thus repeatedly stop.

(d) would there be a greedy solution if instead of optimizing the number of boxes, she instead seeks to fill the largest possible fraction of the space in the trunk? why or why not?
a) The greedy algorithm for this problem would be to load the largest bags first, followed by the next largest, and so on until all the bags are loaded.
b) This problem does not have the greedy-choice property because there may be a situation where loading the largest bag first does not result in the optimal solution.
c) This problem has the optimal substructure property because the optimal solution to the problem can be constructed from optimal solutions to subproblems.
d) There would be a greedy solution if she instead seeks to fill the largest possible fraction of the space in the trunk because the largest bag would always be loaded first, followed by the next largest, and so on.
