Answer:

B. Symmetric key encryption

Explanation:

Symmetric key encryption is one in which a single encryption key is sent to the receiver so both sender and receiver share the same key. In this type of encryption, the sender uses a particular key to encrypt the data and sends the encrypted data (cipher data) to the receiver and then the receiver uses the same key to decrypt the data.

Public key encryption, or asymmetric encryption uses two keys - a private key and a public key. The public key is know to everyone while the private key is known only to those for whom the message is intended. An application of this type of encryption is in SSL (Secure Sockets Layer) -  a protocol for transmitting data privately on the internet.

Private key encryption is not exactly one of the encryption methods but rather, a private key and a public key are used in encryption.

The best option is therefore <em>symmetric key encryption</em>.

<em>Hope this helps!</em>

Assume the system with 256B memory and 64B cache and the block size of 16 bytes. I.e., there are 4 blocks in the cache.
Arada [10]

Answer:

a. 100%

b. 50%

c. 66.6%

Explanation:

a.

The memory references D6, 58, D8, 9A, DE and 5C all results in misses and the miss ratio is 100 (that is , 6 misses/ 6 references*100 = 100%)

b.

If fully associative cache is used, there will be a 3 cache misses with miss ratio of (3/6*100) = 50%.

c.

With a 2-way set-associative cache, 4 memory reference misses will occur, with a miss ratio of (4/6*100)= 66.6% misses.

finlep [7]

Answer:

Network Printer

Explanation:

A network printer is a type of printer that is accessible by network connections, making it available for use by other computers connected to that network. The network can either come from the printer or from a local computer provided to create network for the printer. Most of them contains a network interface card that allow them connect directly to a local network from which computers can then access them. This is different from a local printer that is directly connect to the computer via USB cable.

Network printer is very advantageous in that multiple network computers can access the printer at thesame time.
