Answer and Explanation:
Given data:
Distance (D) = 40 KM
Speed of light in the fiber =Distance/ speed of light in the fiber
a) Delay (P) = Distance/ speed of light in the fiber
= (40,000 Meters/2×108 m/s)
=( 40×103 Meters/2×108 m/s)
Propagation delay (P) = 0.0002 seconds or 200 microseconds
b)
if propagation delay is 0.0002 Seconds roundup trip time (RTT) will be 0.0004 Seconds or 400 micro Seconds
Essentially since transmission times and returning ACKs are insignificant all we really need is a value slightly greater than 0.0004 seconds for our timeout value.
c)
The obvious reasons would be if the data frame was lost, or if the ACK was lost. Other possibilities include extremely slow processing on the receive side (late ACK).
Or Extremely Slow Processing of the ACK after it is received back at the send side.
Answer:
Boot Sector virus is when a virus infects the Boot Sector of a hard disk. A Boot Sector is the initial files necessary to start an OS and other bootable programs. It is typically infected by these viruses when started with infected floppy disks, however the boot virus does not have to be successful to infect your computer. Once infected, the virus tries to infect every other disk.
Hope this helps!
Answer:
System Software
Explanation:
Anything on your computer that includes system services, configuration files, and many other computer preferences is called system software. System software like the operating systems themselves, browsing software, and many other software programs offers platform to other software. It falls in between the user and the hardware. Once your Operating System is installed, the system software comes preinstalled. System software constitutes every program file on your computer that interacts in a very basic level with the hardware.
When a function template has two parameterized types, one as the return value, and one as an argument, then THE FIRST TIME MUST BE EXPLICITLY CODED.
Explanation:
- The act of implicit and explicit coding, and implicit and explicit code, is defined by context of execution of additional behavior or type setting/casting. Specifically, implicit or explicit methods are defined by the contexts in which they are meant to be used.
- The explicit coding discipline favors clear and explicit expression of intent in the code.
- The uses-cases dictate the structure of the application. What the application does should not be implicitly hidden in an organization that the framework is trying to dictate you. Avoid having folders like /controllers, /views at the highest level of folders organization, in favor of folders containing features and use-cases: /categories, /products, etc.
- Template parameter represents a type that has not yet been specified, but that can be used in the template function as if it were a regular type.
If your heart rate exceeds 185 beats per minute during exercise, it is dangerous for you. Your target heart rate zone is the range of heart rate that you should aim for if you want to become physically fit. It is calculated as 60 to 80 percent of your maximum heart rate.
