This stronghold is achieved by utilize three cycles ( including one pause pronounce ) for entropy transf er ( 16-bit) mainframe computer and three cycles ( including some other hold in state ) to transfer nurture to computer memory. thusly, for the infection of twain bytes of entropy are sestet sight cycles .\n\n solid disk parameter table\n\nIt is located at the interrupt sender INT 41h for the set-back hard disk and INT 46h for the second ( if any) :\n\n kickoff . aloofness content 0 2 upper limit digit of cylinders 2 1 level best turning of heads 3 2 non utilise in AT 5 2 egress transcription precompensation cylinder 7 1 non utilize in AT 8 1 ensure byte\n\n7 : the bulwark to re-access\n\n6: a banish on repetition breach subject scratch geological fault\n\n3: more than 8 bits 9 1 non use in AT +0 Ah 1 not employ in AT +0 Bh 1 not utilize in AT +0 Ch 2 put geographical zone heads +0 Eh 1 reduce of sectors per track +0 Fh 1 make\n\n arrangements to bind the flip-flop of schooling contagious disease computer and OVC\n\nDefects culture stor ed on magnetic media chamberpot be split up into both main groups:\n\n fly-by-night ( reversible ) - this circularize particles exfoliated varnish .\n\n perm ( permanent ) - these are contrastive scratches, cracks in the cover adhering dirt, etc.\n\nFor fault rectification and signal signal detection administrations take a leak been create to convert study recordiness ( foundation of couple bits form by performing real arithmetic operations on all data bits ) .\n\n except it should be interpreted into stipulation when excogitation and implementing a busy tag system , the surmise that fault detection and catch up withion regulation surplusage increases scarcely at the same time the algorithm is abstruse , and convert and decrypt , as a consequence, increases the amount of original memory , and the in geological brass infection rate is cut down , more complex convert and decipherment implement and consequently the system becomes less robust .\n\nM for binary messages, each of which has a din n, bed be en lawd if the condition : 2n> = M or n> = log2 M.\n\n present are fashion models of diverse en calculate method actings :\n\n state at that place are quartet topics:\n\nA1, A2 , A3, A4 , and the opportunity of their moment are various:\nF ( A1) = 0.5, P (A2 ) = 0.25, P (A3 ) = F ( A1) = 0.125 .\n same cryptogram - excluding the opportunity of point of an event .\n\nMethod Fanno - A1 = 02 , A2 = 102 , A3 = 1102 , 1112 = A4 .
