For the paper “Improving Map Reduce Performance in Heterogeneous Environments” answer the following questions about the experimental comparison of the Longest Approximate Time to End (LATE) scheduler and the original Hadoop scheduler. The following graphs are from the paper. They show the performance in terms of the completion time of the map-reduce application for three versions of the scheduling algorithm (No Backups, Hadoop Native, and LATE), normalized to the Hadoop Native case.  Explain the following: Why does the ‘No Backups’ case perform so much better when there are no stragglers vs. when there are stragglers? Why does the LATE scheduler perform better than Hadoop Native in both cases (i.e., what are the main problems of the native Hadoop scheduler that are addressed with the LATE scheduler?)

I understand that using Honorlock will be required for the midterm and final exam of HEAL 230.

Below are two common misconceptions about evolution by natural selection. Choose one of these two misconceptions and 1) explain why it is incorrect and 2) explain the correct evolutionary concept.

Two common misconceptions (incorrect views) about evolution by natural selection: Evolution by natural selection is random, and random processes could not lead to structures as incredibly complex as those we see in living organisms Species alive today descended from other species alive today  

Influenza viruses contain an RNA genome surrounded by a protein capsid (coat) and a lipid envelope (membrane). They rely on two surface proteins (haemagglutinin, HA, and neuraminidase, NA) to bind to host cell receptors to gain entry. Once inside a cell, influenza viruses hijack the cellular functions and effectively turn the cell into a virus producing factory, with the synthesis of viral genome and proteins allowing virus particles to assemble and exit the cell. This overall process is representative of what viruses in general accomplish when infecting cells. Copyright 2024 by Edmonds College Department of Biology. All rights reserved.

Based on this information and your understanding of the definition of life, are viruses alive? Please explain. Include in your answer specific definitions of what it means to be alive (recall that the Freeman text describes 5 fundamental characteristics of life – what are these five characteristics?) and address whether or not these apply to viruses.  

Scenario: You are working as a network engineer in a company that uses a client-server architecture for its applications. The development team is implementing a new messaging system that will allow users to send messages between hosts. Your role involves ensuring that messages are transferred reliably between clients and the server while managing the communication protocols. Question: How do you transfer messages between hosts, and what mechanisms are responsible for managing the reliability requirements of a conversation? 

Scenario: You are a network security analyst in a company that relies heavily on TCP for its web applications and services. Recently, you have noticed unusual traffic patterns and potential security breaches. To address these concerns, you need to investigate the security issues associated with TCP and how they might affect the integrity and confidentiality of your network communications. Question: What are some common security issues associated with TCP, and how can they impact network communications? Provide explanation to anyone to illustrate these vulnerabilities.
