Answer: C) spin-lock with test and set
Explanation:
In spinlock, when a thread locks a spinlock then it continuously retrying locking until it succeeds. Spinlock is the lock that cause thread and continuously check that whether the lock are available or not for synchronization.
So that is why spinlock is best synchronization solution as it is not allowing any another thread.
On the other hand, in mutex thread try to lock a mutex and then, it automatically go to sleep mode before locking and immediate allow another thread to run.
In python 3.8:
def func(value_list):
lst = [x for x in value_list if type(x) == int or type(x) == float]
return sum(lst)
print(func(["h", "w", 32, 342.23, 'j']))
This is one solution using list comprehensions. I prefer this route because the code is concise.
def func(value_list):
total = 0
for x in value_list:
if type(x) == int or type(x) == float:
total += x
return total
print(func(["h", "w", 32, 342.23, 'j']))
This is the way as described in your problem.
Answer: a replay attack, a replay attack is used so that the attacker can go sniff out the hash, and get whatever they are trying to get, then once it goes to the attacker it will go back to the original connection after replaying the hash
Four binary digits. So letter D.
Answer:
C. IPIP
Explanation:
This protocol is known as an IP that stands for Internet Protocol. This protocol handles the simple task of making sure that the information is routed correctly to and from the corresponding computer machines through the internet. The sending and receiving machines are identified through their Internet Protocol Addresses which lets the protocol know exactly where the information is going and being sent from.
