Answer: Safety effort of system is defines as the measures that are taken to provide and maintain the protection of the system.There are several methods ,tool and efforts made for the system security .Benefits of the system security are as follows:-
- Takes control over the hazardous situation and maintain the security
- System security will also increase the development of the system easily.
- Approach towards the analyzing of the system function

Answer:
Explanation:
The minimum depth occurs for the path that always takes the smaller portion of the
split, i.e., the nodes that takes α proportion of work from the parent node. The first
node in the path(after the root) gets α proportion of the work(the size of data
processed by this node is αn), the second one get (2)
so on. The recursion bottoms
out when the size of data becomes 1. Assume the recursion ends at level h, we have
(ℎ) = 1
h = log 1/ = lg(1/)/ lg = − lg / lg 
Maximum depth m is similar with minimum depth
(1 − )() = 1
m = log1− 1/ = lg(1/)/ lg(1 − ) = − lg / lg(1 − )
 
        
             
        
        
        
Answer:

A. Static
Explanation:
Static page (also known as flat page or stationary page) is a web page that is delivered to the user's browser exactly as it was stored. They are web pages that contains fixed content. It is the easiest and most basic type of website. It is an unchanged page retrieved from a file on a web server. It is in direct contrast with dynamic websites that do not require any web programming or data base design.
