Answer:
1. Where,
2. From
Explanation:
In SQL query language when working on a database, a user can use certain clauses to carry out some functions.
Hence, The WHERE clause allows us to select only those rows in the result relation of the FROM clause that satisfy a specified predicate.
This is because the "Where clause" selects the rows on a particular condition. While the "From clause" gives the relation which involves the operation.
Answer:
Network mapping.
Explanation:
Network mapping seems to be the method of mapping the server visibly and rationally in order to determine the relations at mid of the network as well as the not same nodes.
- Network mapping is the practice of security checking using software to search against services running on networks.
- Network performance applications and software contains certain network mapping functions that customize the network
Answer:
it should be d

please mark this as brainlists i could really use it
Answer:
Chord is a set of rules for a peer-to-peer distributed hash table it collects key-value sets by allotting keys to several computers (known as "nodes"); a node will collect the values for all the keys for which that is reliable. Chord defines how keys are allocated to the nodes, and how a node can determine the value for a distributed key by first locating the node liable for such key.
Explanation:
A chord is a peer-to-peer lookup service. It Resolves the difficulty of establishing a data item in a combination of shared nodes, considering various node arrivals and removals The most crucial operation in most peer-to-peer method is the efficient position of data objects.
It is able of supporting only one operation i.e. given a key, it maps the key on a link.
Algorithm:
Algorithm shows working of the chord:
// x is a node used to find successor of id
x.find_successor(id)
if (id (x; successor])
return successor;
else
// query is being delivered around the circle
entrance successor.find_successor(id);
Answer:
Digital level logic through machine level
Explanation:
Infrastructure as a Service can be regarded as computing cloud services that allows computation, storage, server in the cloud.it helps the user to access infrastructure in the cloud
Digital level logic which is in digital circuit that allows boolen expression, it allows signals as well as sequence to be expressed in form of numbers, it is usually view as been complicated but not.
It should be noted that Infrastructure as a Service (IaaS) replaces the Digital level logic through machine level of the computer hierarchy with an Internet-based infrastructure.
