Question and answer
What is a key? What are the differences between private key and public key encryption? Provide examples of each.
In cryptography, a key is a piece of information (a parameter) that determines the functional output of a cryptographic algorithm or cipher. Without a key, the algorithm would produce no useful result. [ In encryption, a key specifies the particular transformation of plaintext into ciphertext, or vice versa during decryption. Keys are also used in other cryptographic algorithms, such as digital
signature schemes and message authentication codes.Public key encryption refers to a type of cypher or code architecture known as public key cryptography that utilizes two keys, or a key pair), to encrypt and decrypt data. One of the two keys is a public key, which anyone can use to encrypt a message for the owner of that key. The encrypted message is sent and the recipient uses his or her private key to decrypt it. This is the basis of public and private key encryption. Read more: ]

Between static and dynamic routing, which one would be the best choice and why
Weegy: It depends on how you want to use these routing options. If you want more connectivity and sharing, use dynamic routing. (More)

Between static and dynamic routing, which one would be the best choice and why
Weegy: With static routes, there will be two "equal cost" paths and your router will load balance between them. You can engineer your "preferred" choices by setting a different administrative distance on separate routes. [ For example: Ip route 10.1.0.0 255.255.0.0 10.0.1.1 Ip route 10.1.0.0 255.255.0.0 10.0.1.2 This will cause you to have two directions to go in order to reach the 10.1.0.0 network and will load balance between them. Ip route 10.1.0.0 255.255.0.0 10.0.1.1 Ip route 10.1.0.0 255.255.0.0 10.0.1.2 10 This, on the other hand, will assign an administrative distance of 10 to the second route. Static routes by default have an AD of 1, and the lower the AD, the more preferred the route is. So in this method, your router will route all 10.1.0.0 traffic to the first router. This is called a floating static route. So what happens if the first router goes away? Nothing! That's because you manually told the router where to send things. Let me clarify things before people jump up and down about this one! Notice that I put the destinations on the same subnet! If you have two separate layer 3 links (separate sub-interfaces if you are running Frame Relay PVCs), then you can, indeed, have some failover that way. Being on two separate interfaces, if a physically connected interface goes down, the router would know that it could not route out that direction, and therefore the second route would enter the routing table. So if you had: Ip route 10.1.0.0 255.255.0.0 serial 0/0.1 Ip route 10.1.0.0 255.255.0.0 serial 0/0.2 10 you would find some failover there if the PVC representing Serial 0/0.1 went away. You can also use a dynamic routing protocol to learn about networks automatically. You would then always have the "best path" in your routing table no matter what the status of your physical links. All routing protocols have some sort of shortest-path or lowest-cost or best-choice algorithm to help you weigh all the options available. Note that with either ... (More)
