Answer:

It is A: Packet metadata is used to route and reassemble information travelling through the internet.

Explanation:

Step 1: The Internet works by chopping data into chunks called packets. Each packet then moves through the network in a series of hops. Each packet hops to a local Internet service provider (ISP), a company that offers access to the network -- usually for a fee

Step 2: Entering the network

Each packet hops to a local Internet service provider (ISP), a company that offers access to the network -- usually for a fee.

Step 3: Taking flight

The next hop delivers the packet to a long-haul provider, one of the airlines of cyberspace that quickly carrying data across the world.

Step 4: BGP

These providers use the Border Gateway Protocol to find a route across the many individual networks that together form the Internet.

Step 5: Finding a route

This journey often takes several more hops, which are plotted out one by one as the data packet moves across the Internet.

Step 6: Bad information

For the system to work properly, the BGP information shared among routers cannot contain lies or errors that might cause a packet to go off track – or get lost altogether.

Last step: Arrival

The final hop takes a packet to the recipient, which reassembles all of the packets into a coherent message. A separate message goes back through the network confirming successful delivery.

What is the purpose behind the Three Phase Commit? It improves upon the two phased commit by requiring that locks be acquired at

Ray Of Light [21]

The answer is a) It improves upon the two-phased commit by requiring that locks be acquired at the start of a transaction.

Reason: The 3PC is an extension or you can say developed from 2PC that avoids blocking of an operation. It just ensures that first n sites have intended to commit a transaction that means it acquires commits or locks before the start of any transaction to avoid any blocking.

Option b) is wrong as it does not allow coordination, it just let all the other sites do their transaction if any other site is blocked, so no coordination is there between sites that they will wait till their coordinator is corrected.

Option c) is wrong as lock operations are shared between other connections as when their coordinator fails, the new coordinator agrees to the old coordinator that they had shared locks before and they can start their transaction.

Option d) is wrong as option a) is correct.

What does ‘‘negotiation’’ mean when discussing network protocols? give an example?

rewona [7]

Some protocols have multiple algorithms to choose from for e.g., cryptographic purposes. During connection set up, client and server negotiate which one they'll use.

One example is the set up of a TLS connection. During the handshake, the client shares a list of its supported ciphers (the 'ciphersuites'). The server responds by indicating the best one that both sides support.

For two integers m and n, their GCD(Greatest Common Divisor) can be computed by a recursive function. Write a recursive method g

konstantin123 [22]

Answer:

In Python:

def gcd(m,n):

if n == 0:

return m

elif m == 0:

return n

else:

return gcd(n,m%n)

Explanation:

This defines the function

def gcd(m,n):

If n is 0, return m

if n == 0:

return m

If m is 0, return n

elif m == 0:

return n

If otherwise, calculate the gcd recursively

else:

return gcd(n,m%n)

To call the function to calculate the gcd of say 15 and 5 from main, use:

gcd(15,5)
