Answer:
- Transform binary or unary M:N relationship or associative entity with its own key.
Explanation:
Transform binary relation is described as the method through which a decimal can easily be converted into binary while the unary relationship is described as a relationship in which both the two participants occurs from the same entity.
In the given case, 'transform binary or unary M:N relationship' can be created using 'the primary key linked with the relationship plus any non-key aspects of the relationship and the primary keys of the related entities' as it displays the existence of a relationship between the occurrences of a similar set of the entity i.e. associative entity here.
Answer: Networking protocols are important as they define a set of rules to be used for exchanging information between computer nodes.
Explanation:
in terms of networking it is required for the source and the destination to have a set of predefined rules which enables the router to send and receive information across the network in such as way that both the ends are able to receive the messages.
The information exchange takes place first by the client by introducing itself to the remote server. the remote server upon receiving the information uses some form of handshaking and acknowledges the client of the receipt of the message.
besides this there are many routing protocols which tells us about the way how packets are sent from the client to the source. There are two types of routing protocols:
1. static routing protocols
2. dynamic routing protocols.
Answer:
B. 11110111
Explanation:
Binary representation of number 9 = 00001001
Binary representation of -9 would involve calculating the twos complement representation of 00001001
First we compute the ones complement of this number by reversing the bits.
00001001 => 11110110
Next we calculate the twos complement representation by adding 1 to the ones complement.
11110110+1 = 11110111
So the final representation is 11110111.
