sequential (24) Electrodes

  https://kamchihau.blogspot.com/2022/09/tcp-and-udp.htm . Ref: https://kamchihau.blogspot.com/2022/09/tcp-and-udp.html . . . John: See the 1st picture. There're 3 types of electrodes. One type is parallel electrodes. One type is fringing electrodes. And, the last type is between parallel and fringing electrodes. . Me: The field line of fringing electrodes are "Bent". . John: Yes,. See the 2nd picture. There're 2 parts. They are part of left hand side and the part of right hand side. Me: OK. John: Which part is correct? Me: Logically, the part of left hand side is correct. That mean, the 1st branch is up cycle and the 2nd brach is down cycle. . John (shaking head): Let me tell you. The part of right hand side is correct either. Me: The right hand side is correct? John: Yes,. That mean the 4th branch is at down cycle. The 1st and 2nd "branchs" are at up cycle, at the same time, the 3rd branch is at down cycle. . Me: If the 3rd branch is at the down cycle, the...

sequential (23) no realistic serial circuit (counter)

Clock line is from the RJ45.  This clock line is shared with by "the register of port A" and the "Counter" as well. Me: OK. John: Now, see the 1st picture. It is a counter.  It say if Q0,Q1,Q2 are high, FF4 toggle. However, FF4 will never toggle. Me: Why will FF4 never toggle? John: The clock-input for FF3 is forever "Down cycle", Q2 is forever low. How can FF4 toogle?  . 1) Normally, when the clock line is Up cycle indeed, the clock-input for FF3 is Up cycle.  2) However, in our case, the clock line is Up cycle indeed.  The clock-input For FF3 keep down cycle.   In code, it is, . if (Q0,Q1,Q2 = high) { The output of the register Port A is enabled.  } . John: If Q2 will not be high, how can the output register of Port A be "enabled"?  ...

sequential (56) Voltage Common different mode

Me: The "black dot" indicate the direction of the flow of the current. . In the upper picture, circuit A and B have same direction of the flow of the current . As a result, the resistance of both circuit is high. John: But, in the lower picture, circuit A and circuit B have different direction of the flow of the current. . As a result, the resistance of both circuit is low. . If (direction of current flow = same) {  resistance of the circuit = high; }   else if (direction of current flow = different) {  resistance of the circuit = low; } .

education (10)

https://kamchihau.blogspot.com/2022/09/httpskamchihau_6.html . Ref:    https://kamchihau.blogspot.com/2022/07/blog-post.html .  John :  999 is the emergency telephone number of Hong Kong. .  if (999) { if (call from John) { bind (999, Kelvin Sim card); <---- Kelvin hack the telecom and add an extra code here. } else { bind (999, emergency's department ); } } . Kelvin: I hack the telecom and bind 999 to my physical address of my Sim card.  Mr.Sao (staff of emergency of Hong Kong): Your Sim card ring 100 times each minute. Because, there're over 100 people calling 999 each minute.  Kelvin: No worry. If John call 999, it bind 999 to my physical address. . Else, it bind 999 to the emergency's department. Now, John call 999 to request an ambulance to pick up Mr. N. You're gonna ridicule Mr.N. Mr.Sao: Fine. But, you must hack the database of the public hospital of Hong Kong and then you provide me with the full details of Mr.N . Kelvin: Deal.  . ____...

sequential (102) Cache comparison pending

  https://kamchihau.blogspot.com/2022/09/httpskamchihau.html . Ref:  https://wodewangzhishime.blogspot.com/2023/12/blog-post_13.html?m=1 . . . John : The picture above explains how Cache's comparison works. Both BA and CA enter the Xor gate.  . If (Xor gate = true) { Tri state buffer = true ; if (tri state buffer = true ) { BV input his value to CV. CV and CV send their signals to parallel output line. } } . Me: Wait a minute.  If Bv input its value to Cv, the Clock line of RJ45 is at up cycle.  However,  if both Cv and CA send a signal to parallel output line,  the parallel output line must be in down cycle.  . John : Yes, you are correct. 

education (33) Quezon students killing

https://kamchihau.blogspot.com/2022/08/httpskamchihau_56.html . Ref: https://kamchihau.blogspot.com/2022/08/httpskamchihau_26.html . John : Miuson is the person in this link . https://kamchihau.blogspot.com/2022/07/httpskamchihau.html?m=1 . Me: Ok . One day of 2004, Kelvin undertake a professor's obligation. He stand at the podium of the lecture's hall of the church of Yandel. . Kelvin: My dearest student. During this lecture, I use electrical cables nearby the house of John as an example. Now, I hack the power plant of Hong Kong. I let those cable burn. How do you feel about this lecture ? Daniel (a student): It's very educational and deityless. . __ . Bradley : Kill those students,  e.g., Daniel.  Kelvin : Please.  Daniel is a stupid student.  He can't learn any hacking techniques from me.  Bradley : I don't care.  Kill him still.  . ___ . Miuson: You told Bradley that Miuson is a stupid student.  He can't learn any hacking techniques from yo...
