How to create json object from variables javascript

1 answer:

8 0

Not entirely sure what you want to achieve, but consider this program:

var a = 'foo';
var b = 'bar';

var c = { first : a, second : b };

console.log(JSON.stringify(c, null, 4));

A json object c is constructed using the values from variables a and b. Is this what you mean?

ad-work [718]

Answer:

a) Time to live field

b) Destination

c) Yes, they have two ip addresses.

d) 128 bits

e) 32 hexadecimal digits

Explanation:

a) the time to live field (TTL) indicates how long a packet can survive in a network and whether the packet should be discarded. The TTL is filled to limit the number of packets passing through N routers.

b) When a large datagram is fragmented into multiple smaller datagrams, they are reassembled at the destination into a single large datagram before beung passed to the next layer.

c) Yes, each router has a unique IP address that can be used to identify it. Each router has two IP addresses, each assigned to the wide area network interface and the local area network interface.

d) IPv6 addresses are represented by eight our characters hexadecimal numbers. Each hexadecimal number have 16 bits making a total of 128 bits (8 × 16)

e) IPv6 address has 32 hexadecimal digits with 4 bits/hex digit

What happens when i expose a disk to magnetic fields?

lesya692 [45]

Answer:

When exposed to the powerful magnetic field of a degausser, the magnetic data on a tape or hard disk is neutralized, or erased. Degaussing is the guaranteed form of hard drive erasure, as such; it serves as the standard method of data destruction.

You have configured your firewall to authenticate a group of 100 users who are in your company. You set up the database of users

svetlana [45]

Answer:

Explanation:

Network Access Control is needed to make sure that only set of verified users access the network.

It makes sure that the users are authenticated and only set of some verified users have access to network.

Set of NAC solutions like Impulse SafeConnect, Extreme Networks, ExtremeControl, Auconet BICS, ForeScout CounterACT, Pulse Policy Secure could be installed in the system which along with basic profiling will make sure authenticated access to the network.

Other than this basic encryption-decryption algorithm can be used in this regard. Network components could use encryption algorithms like RSA and DES. These algorithms will make sure that the information from database side is well encrypted. Once that information goes to the network component. They can decrypt the encryption by generating relevant key using the same algorithm.

This will only allow authentic users to access information and also it will stop the leakage of information in between the transmission because of encryption.
