Answer:
a) the average CPI for machine M1 = 1.6
the average CPI for machine M2 = 2.5
b) M1 implementation is faster.
c) the clock cycles required for both processors.52.6*10^6.
Explanation:
(a)
The average CPI for M1 = 0.6 x 1 + 0.3 x 2 + 0.1 x 4
= 1.6
The average CPI for M2 = 0.6 x 2 + 0.3 x 3 + 0.1 x 4
= 2.5
(b)
The average MIPS rate is calculated as: Clock Rate/ averageCPI x 10^6
Given 80MHz = 80 * 10^6
The average MIPS ratings for M1 = 80 x 10^6 / 1.6 x 10^6
= 50
Given 100MHz = 100 * 10^6
The average MIPS ratings for M2 = 100 x 10^6 / 2.5 x 10^6
= 40
c)
Machine M2 has a smaller MIPS rating
Changing instruction set A from 2 to 1
The CPI will be increased to 1.9 (1*.6+3*.3+4*.1)
and hence MIPS Rating will now be (100/1.9)*10^6 = 52.6*10^6.
I used computers for 3 years now and i think its B
Answer:
a) Generate a new public and private key
Explanation:
You encrypt a message using the recipient's public key and the recipient decrypts the message using his own private key. Only the public key can be known by an external agent. The private key is for the individual and is not expected to be shared. In the event that the recipient cannot decrypt the message, it is unsafe to send one's private key to him. He does not even need one's private key to decrypt the message, he needs his own private key.
The best thing to do is to generate another means of security by generating new public and private key so that the sender encrypts the message with the new public key and the receiver decrypts it using his new private key.
Option B is wrong because, if the encryption is removed, the aim, which is to secure the message from intruders is not achieved.
Playing Minecraft on a public server can take the game to a whole. This will help your kid learn social skills, such as cooperating, while there are some family-friendly servers for the Pocket Edition most server admins can “roll back” your building to the state it was in.
Explanation:
- For Minecraft, you'll need to forward TCP port 25565 . You'll also need to enter your server's local IP address as the Output IP or Server IP for the forwarded port. This tells the router which device to point at. To find your server's local IP, open a command prompt and enter ipconfig.
- They are safe for the most part, however they do expose you to the following risks, which can generally be negated by simply joining reputable servers. Some servers may ask users to set up an AuthMe password. If you decide to enter a password here, never ever enter the password of your Minecraft account.
- You can divide public Minecraft servers into two types:
- Whitelisted servers are protected by a whitelist — that is, a list of usernames that are allowed to join the server. To join a whitelisted server, you need to apply to have your Minecraft username added to the whitelist. Typically, this involves filling out a form and waiting a few hours or days.
- Non-whitelisted servers do not have a whitelist, which means anyone can join the server simply by entering the server’s address in their Minecraft client, as shown above.
- Applying for a whitelisted server can be a bit of a drag especially when you have an impatient eight-year-old tugging at your sleeve but it does provide an extra degree of reassurance that all the players on the server are known to the server administrators.
