Many companies are undergoing server virtualization. This is the concept of putting multiple "virtual" servers onto one physical device. The payoffs can be significant: fewer servers, less electricity, less generated heat, less air conditioning, less infrastructure and administration costs, increased flexibility, less physical presence (that is, smaller server rooms), faster maintenance of servers, and more. There are costs, of course, such as licensing the virtualization software, labour costs in establishing the virtual servers onto a physical device, labour costs in updating tables, and access. But determining the return on investment can be a

As a system engineer, draw a Sequence case diagram of the following scenario: An Alert system notifies the user and the police or fire department if there is a fire or a security breach at a Home Appliance Control System (HACS) equipped home. The hardware used to detect a fire or intruder interacts with HACS uses sockets as does most of the communication. Also, the police department and fire department provide application program interfaces that HACS can use to notify the respective departments.
Give an example of a scenario in which the complete denial of a service to a user (in other words, the user receives no answer from the computer) causes a significant issue for that user. Another scenario in which a 10 percent denial of service (that is, the user's calculation continues, but at a pace 10 percent slower than normal) represents a significant issue for that user is described below. It is possible that illegal access to a computer system results in a 10% denial of service to the legitimate users of that computing system. If so, how would you go about it?
A process' memory use is directly related to the number of threads it has started. What is the connection between the amount of memory consumed by processes and the number of active threads per process?

The term "perpetual resource denial" refers to an issue that occurs in multitasking when a process is denied required resources.
Alisa works at a Medical Insurance Company. She oversees the claims department and her objective is to increase efficiency in the company - each unit must process a minimum number of claims per day. To achieve this goal, she installed a software system that monitors: Number of claims processed by each clerk Number of keystrokes performed by each clerk Log information when each clerk is in or out of his post. This system allows her to check all the above information in real-time on her screen. She can also see all emails sent by each clerk regardless of whether the email is business related or not. Should she use this system and if so, does every clerk need to be notified? Do you think any limits should be placed on companies using such systems? discuss. 1.
