Answer:
168 (although the =< must be corrected to <=)
Explanation:
int count = 0;
for (int row = 4; row <= 15; row++)
for (int col = 0; col < 13; col = col +2)
count+=2;
The inner for loop runs 7 times (for col = 0,2,4,6,8,10,12). Anything higher is not less than 13. Therefore the inner loop increments count by 2 seven times, i.e. it increments count by 14.
The outer for loop runs 12 times (for row = 4,5,6,7,8,9,10,11,12,13,14,15).
If the count is incremented by 14 twelve times, you are incrementing it by 14*12 = 168.
Therefore the count goes from 0 to 168 after the nested loops.
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.
Answer:
The benefits of relying on System Development Standards is explained below.
Explanation:
There are many benefits of having a Well Defined Systems Development. It helps in having a pre - planned and well defined structure before the project starts. It helps in having a Clear view of the whole project and also each phase of the whole System Development. It helps in having an understanding of cost required and the revenues generated at each phase of the whole system development. It helps in having an understanding of the goal of each phase and procedures need to be followed for that particular goal. It also helps in having the quality checked and the improvements need to be made for the desired quality.
