Look at the image for more information.
I have to type 20 characters here so...
That would be a star network. A star network isn't necessarily shaped like a star, of course, but like you mention this topology has a central device, usually a server of some sorts, and then many different endpoints coming out of that central device, such as the client computers for the server.
Answer:
001*|1*00
Explanation:
The language consists of strings in {0,1} that either start with 00 or end with 00 and have no more zeros.
The requirement can be divided into two parts:
1) Strings that start with 00 and have no more zeros
2) Strings that end with 00 and have no more zeros
Generating regular expressions for these parts:
1) 001* - starts with two zeros and can have zero or more 1s later
2)1*00 - starts with zero or more 1s and ends with two zeros
So on combining with the or operator(|), the overall regular expression for the strings in the language becomes:
001*|1*00
Answer: NOR or XNOR gate
Explanation:
In NOR gate we get a high value of the output only when its input has a low value. i.e. for 0 and 0 we get a value of 1.
In XNOR gate which is the compliment of the OR gate we get the output as 1 when all the inputs are 0.
