    if u find (which i did sum wierd way) ∑α ∑αβ ∑αβγ u could do this x^3 - (∑α)x^2 + (∑αβ)x - (∑αβγ) = 0 then: ∑α = 4 ∑αβ = 3 ∑αβγ = -2 so x^3 - 4x^2 + 3x - (-2) = 0 and since alpha satisfies the eqn α^3 - 4α^2 + 3α +2 = 0 now times that thru alpha to get: α^4 - 4α^3 +...

    Checksum help!

    once u divide by 256 u get the remainder and that is the final number u gotta add the bits together....so it mite b 27|18|107|3|74|0|63| and the checksum will be 36 reason 27+18+107+3+74+0+63=292 292>255 hence 292/256=1 and 36 remainder checksum =36

    A good way to study the IPT core topics

    asymmetric uses a widely available public key for encryption and a secret private key for decryption symmetric encryption uses the same key for both encryption and decryption explain the difference between Sheilded twisted pair and unshielded twisted pair and their uses.

    Start/Stop bit?

    stop and start bits are the bits placed on the front and end of a data blocks in asynchronous transmission. the start bit informs the recieving device that another character is on its way, while the stop bit tells the reciever that its finished sending and to wait for another start bit. and i...
