Answer:
A. One
Explanation:
Symmetric key cryptography makes use of one key. The same key is used for both encryption and decryption. This is different from asymmetric cryptography where separate keys are used for the two operations. Some examples of symmetric cryptography include:
- Advanced Encryption Standard (AES)
- Data Encryption Standard (DES)
- Triple Data Encryption Standard (3DES)
Answer:
Explanation:
The population in western richer countries is decreasing but the population in some poorer developing countries is increasing and normally in the poorer communities where education is minimal or not encouraged then men and women tend to get married young and have many children. Population management is not necessary because when men and women are educated and have good standard of living with a good social system of caring for the old then married couples will tend to have one or two kids or none at all. Population control was practised by PrC and it managed to alleviate 60% of the people out if poverty and reduced the population by implementing one child policy. Now China has more male than female creating social problems of finding a wife. In the West with good social system to care for the elderly more couples are not having children. In the west where living conditions and educational level are better the Caucasian race is not having that many children as the other races in developing countries. Education and financial independence of women will encourage married women to have one or two kids so that they can still pursue their career after marriage. With modern contraception you can delay having children until you are ready for them. The concept of delaying marriage to reduce population does not hold true. However the whites’ population is decreasing every year as compared to the other non white races. The reason is that in the poorer non white countries the population is higher because of subservient position of the women who have no say in birth control

Answer:
FULL neighbor state.
(FULL/DR or FULL/BDR)
Explanation:
The fact that the routers are neighbors is not enough to guarantee an exchange of link status updates; they must form adjacencies to exchange link status updates. Adjacency is the next step after the process of establishing neighbors. Adjacent routers are routers that go beyond a simple Greeting exchange and act in the database exchange process. To reduce the amount of information exchange in a given segment, OSPF selects a router as a designated router (DR) and a router as a designated backup router (BDR) in each multiple access segment. The BDR is chosen as the backup mechanism in case the DR fails. The idea behind this is that routers have a central point of contact for the exchange of information. In order to verify if two routers have established an adjacency, you can use the command: show ip ospf neighbor.
Here is an example:
R1#show ip ospf neighbor
