+Spóźniłem się 15 min. a on gada coś i nic nie rozumiem, bo tak cicho jest.
+
+Coś o matmie gada, obliczenia wykonuje jakieś teoretyczne.
+
+Pan wykładowca trzyma mikrofon, ale do niego nie mówi.
+
+Na dany cykl robi coś tylko raz.
+
+ALU – układ wykonawczy. Składa się z 2 wejść na dane, wejścia na kod operacji, wyjścia na wynik i wyjścia na flagi.
+
+2 testy obowiązkowe, projekt nieobowiązkowy.
+
+Potencjalnie możliwy egzamin ustny dla osób, chcących wyższą ocenę.
+
+„Jakbym umiał zrobić urządzenie do teleportacji, ale nie wiedział jak ono działa, to i tak ludzie by to kupowali.” ~~ Piękne słowa Pana Wykładowcy
+
+Z punktu widzenia procesora ram to rom.
