B).

Can the design of computer architecture improve security?

Select one:

a. Yes, computer hardware architecture can improve security.

b. Yes, but only for large computers.

c. No, for security you need software like virus detection and firewalls.

d. No, hardware has nothing to do with security.

A).
What does ubiquitous computing mean?
Select one:
a. Compressed computing.
b. Computing everywhere: Ubiquitous means appearing to found everywhere. So, ubiquitous computing means computing everywhere.
c. Very fast computing.
d. Ambiguous computing.
B).
Can the design of computer architecture improve security?
Select one:
a. Yes, computer hardware architecture can improve security. Computer hardware architecture can definitely improve security.  
b. Yes, but only for large computers.
c. No, for security you need software like virus detection and firewalls.  
d. No, hardware has nothing to do with security.
C).
Can you simulate Random Access Memory using Logisim?
Select one:
a. There is no need to simulate RAM.
b. No, Logisim cannot Is it possible to simulate the function of an OR gate in Logisim using NAND gates only ?
simulate RAM.
c. Yes, Logisim has the capability to simulate RAM. It can be simulated.
d. Why would I do that?
D).
Is it possible to simulate the function of an OR gate in Logisim using NAND gates only ?
Select one:
a. Yes, it\'s possible using three NAND gates.   Using 3 NAND gates, it can be simulated.
b. Yes, it\'s possible using two NAND gates.
c. Why should I do that? Logisim has OR gate already.
d. No, it\'s impossible.
