Software vendors and enterpreneurs who try to introduce an innovative software product to a specific organization or an entire market. Enter a long and tedious process. During this process the market and various organization evaluate the product from different prespective such as software robustness manufacturer reliability and corporate need for the product. The vendorss and enterpreneurs engaged in this process encounter decision crossroads for which no relevant guidance exists the lifecycle of an information system includes the various phase that a software product goes through starting with its conception all the way to the stage when it is no longer available for use. Elaborate each phase?

Develop R code:
2. To find out whether a new serum will arrest leukemia, 9 mice, all with an
advanced stage of the disease, are selected. Five mice receive the treatment and 4 do not. Survival times, in years, from the time the experiment commenced are as follows:
Treatment 2.1 5.3 1.4 4.6 0.9
No Treatment 1.9 0.5 2.8 3.1 -

At the 0.05 level of significance can the serum be said to be effective? Assume the two distributions to be normally distributed with equal variances.

Whiles speaking with the lead investigator in a case, you survey the room in which the computer equipment is located. On one side of the room, there is a large bookshelf with up-to-date books on computer topics, a nearby table has current computer magazines, a new scanner is attached to the computer and the computer is a new model with state-of-the-art equipment
With the information, what can you deduce about the use?
How will this affect your investigation?

Imagine you have a standard web server containing a movie segmented into chunks and encoded at constant bitrates of 200, 500 and 1000 Kbps. Assume an additional 320 bytes of HTTP response overhead is required to encapsulate and send each chunk in response to GET requests from a DASH client. A single DASH client is connected to this server over a path exhibiting 350ms RTT and offering 16000Kbps in each direction at the IP layer. With the appropriate use of diagrams and clear descriptive text: [20 Marks: 2 + 6 + 12 ] • What is the path's BDP? • Assume the TCP layer's MSS is 1460 bytes, how long would it take for the DASH server's TCP layer cwnd to reach and exceed BDP during Slow Start from an initial window (IW) of 10 MSS? • If the TCP stack at the DASH server begins in Slow Start with IW=10 MSS for the transmission of every chunk, how long does it take to transmit HTTP-encapsulated 4-second chunks encoded at the three representation rates? (Assume no packet losses or packet reordering along the path.
