W#hat is the Present cabling used in Ethernet? and present
days networks?? And What is the mostly used topology now a
dyas?
Answer Posted / abhay sunder
all depends on ur requirement:---
for eg:for local need ie if u want to use cctv cameras with ur networks...let say ,,so requirement is small then u use a BUS topology becoz that is of low cost...
but if u r using large networks then STAR is prefered...(in companies).but it is costier.....COST also matters a lot......
regarding wires:for shorter distances ie within 100-600-800metres twisted wires are used .......for longer distances coaxial cables are used.......even u can use coaxial 4 shorter diastances but with twisted pair interference is less(becoz interference is balanced for both wires in case of twisted which is RG-59 standard with 75ohm )

.We want to compare the performance of a single threaded disk server with a multithreaded 1. Suppose the server takes 25 ms to receive a request for work from client, dispatch the request for processing and actual data request processing when reqd. Data is in main memory. If the reqd. Data is not in the main memory a real disk operation is needed and an additional 75 ms are reqd. On the average. On the average 25% of the clients requests access the disk. During the disk I/O period the thread waits. Assume that there is no other process in system when the server is running. How many requests can the server handle per second if its a)single threaded b)multithreaded
