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.
Well, you need to partition your hard drive. Partitioning your hard drive designates usable space on your hdd.
And you need to format your hard drive. Formatting installs a file system on to your hard drive, it allows the operating system to read, write and overall understand the data stored on the disk. Without it, an OS cannot keep track of file locations, nor can it typically identify already used sectors (space) on a hdd.
However, neither of these two concepts are tests.
Answer:
continual user involvement gives the flexibility to analyze the requirements in right direction. because there is continuous meetings with the end user and he can provide right direction or avoids wrong interpretation of the requirement
Explanation:
continual user involvement is useful when we are following agile methodology where we are building complex systems. it is not useful for simple sytems and following waterfall methodology
Answer:
1.) Write the formula, which assigns double x to double n raised to the double z power.
Answer: 2\times x → 2\times n^(2\times z<u>)</u>
2.) Write a formula, which will add 5 to the cube of double t times double n, and assign it to double x.
Answer: 5\plus 2\times t^3→2\times x
3.) Write a formula, which will assign double x to square root of the sum of the squares of the lengths of the two legs of a triangle. Declare double leg1, and double leg2, in order to find the hypotenuse. (Pythagorean Theorem)
Answer: 2\times x → \sqrt \{(l^2)_1 + (l^2)_2\}= hypotenuse
4.) Write a program that find the distance between two values on the number line by taking the absolute value of their difference. Assign the answer to double x. The two numbers have been declared as follows:
double num1, num2
Answer: length = \sqrt\{|num2 - num1\|} → 2\times x
