made easy test series
consider a disk has 150 cylinders numbered from 0 to 149. currently the disk arm is at 80 and moving towards higher cylinders. there is disk access requests for cylinders are 30, 78, 96, 123, 141 ,15, 13, 68. what will be the absolute difference traversed by R/w head whwn CSCAN and CLOOK is used?

confusion - computer networks
Do we actually need ip and Mac addresses both at same time for the computer for communication? Why we not use Mac instead of ip address since Mac is also the unique address globally? Why we not use ip instead of Mac Since both are unique but why we use both for computer networkws?

Gate applied
Can some one please do a pumping lema on L = {a^(2n+1) | n>=0 } I know Finite automata can be easily made and hence it is a regular language, but the pumping lema test fails for this implying it is a non-regular language (I am sure I am doing the pumping lema wrong) can someone please do a pumping lema for this so that I compare my solution and rectify my mistake

Made Easy 2022 test series, CD-1 question
Consider the following syntax directed definition: What type of SDT is this? S-attributed L-attributed Neither Both Due to production #2 and #3, it should not be L-attributed as parent is taking value from its child. Also, as semantic rules are written anywhere in the RHS of the production, it is not S-attributed. Given answer in test series : L-attributed

Topic : Digital Logic - Adders
I am very much confused while solving the questions involving adder circuits like Half Adder, Full Adder, Ripple Carry Adder, Carry Look Ahead Adder, etc. I can solve none of the questions, and leave almost all questions involving them. My concept ... me some good source from where I can learn them and practice questions on them. It would be really helpful for me.
