Consider a computer network of a social networking web site in which 7 routers are connected with each other using a dedicated wired point to point link. Each link is of 5 meters and cost of wire is 100 PKR per meter.
In view of the above scenario answer the following questions and provide yours to-the-point answers in respective tables.
Note: Give you solution with all relevant calculations in given tables.
Wish You All The Best
Here 7 routers are given which are connected with a mesh topology, you have to find how many links they are connected through?
and if you add one more router in the current mesh, how many links now you have to add?
use this formula:
no. of links= n(n-1)/2
where n = number of nodes
let us solve one as an example:
suppose we have 5 routers in a mesh and we have to find the number of links:
no. links= n(n-1)/2
= 5(5-1)/2 = 10 links
Ab to smajh aa gaya hoga.. if not, all of us should discuss more..
oh thanks mjhe samjh lag gaye
yaar ye jo assignemnt hai complete nai aa rhi
i understand the formula but i dont understand before and after in question... please someone send me clear ans for that...
i think yeh assignment kisi ko b nae ati
please share how to calculate cost and hint answers plz
there are 7 routers are given which is connected with mesh toplogy so
the no of links=7(7-1)/2 =21
the no of links=8(8-1)/2=28 kindlyyy tell me is it correct??
links = 21
before hn yeh
thn wire is equal 5 meter
and each wire cost is equal 100
wire cost h 500
agr hum aik router bhi lgy to 28 links ho gy
r ap wire pr link wire link ko devide krn thn ans a jy ga
cost find krny ki smjh nai ai
500 total h before b r aftr b
to 21 links hn
This is the right solution..
In this way both parts should be done..
21 kaha se agaya yaha pr ... g
