Answer:
Option B is the correct answer for the above question.
Explanation:
DAP is a protocol technology that is used for the client and discovered by X.500 in 1988. Its use for the client host on the network. The operation of this protocol is --- Read, Bind, Search, List, Compare, Add and Modify the data.
The above question asked about the protocol which is searched by X.500 and used for the clients. So the answer is DAP which is stated by Option B hence this option is correct while other is not because--
- Option 'A' states about DIB which is not a protocol. It is used by X.500.
- Option C states about DIT which is not used by X.500.
- Option D states about LDAP which can be used for client or server.
Answer:
Broadcast topology is defined as each host exchange data or information with other hosts in a network medium. It works on the principle of logical topology. As, it determines across the medium how hosts communicate in a network.

Theoretical Scope
<span>How general is the theory? That is, how widely applicable is it? In most cases, a theory that may only be applied within a fairly narrow set of circumstances is not considered as useful as a theory that encompasses a very wide range of communicative interactions. The ideal, of course, is a theory that succinctly explains the nature of human communication as a whole.
</span>Appropriateness
<span>Theories are often evaluated based upon how well their epistemological, ontological, and axiological assumptions relate to the issue or question being explained. If a theory recapitulates its assumptions (if it is tautological), it is not an effective theory.
</span><span>Heuristic value
<span>Some theories suggest the ways in which further research may be conducted. By presenting an explanatory model, the theory generates questions or hypotheses that can beoperationalized relatively easily. In practical terms, the success of a theory may rest on how readily other researchers may continue to do fruitful work in reaction or support.
</span></span>
<span>Validity
<span>It may seem obvious that for a theory to be good, it must also be valid. Validity refers to the degree to which the theory accurately represents the true state of the world. Are the arguments internally consistent and are its predictions and claims derived logically from its assumptions? Many also require that theories be falsifiable; that is, theories that present predictions that--if they prove to be incorrect--invalidate the theory. The absence of such questions significantly reduces the value of the theory, since a theory that cannot be proven false (perhaps) cannot be shown to be accurate, either.</span>
<span>Parsimony
<span>The law of parsimony (Occam's razor) dictates that a theory should provide the simplest possible (viable) explanation for a phenomenon. Others suggest that good theory exhibits an aesthetic quality, that a good theory is beautiful or natural. That it leads to an "Aha!" moment in which an explanation feels as if it fits.</span>
Openness <span>Theories,
perhaps paradoxically, should not exist to the absolute exclusion of other theories. Theory should not be dogma: it should encourage and provide both for skepticism and should--to whatever degree possible--be compatible with other accepted theory.</span></span></span>
Answer:
Periodical Literature
Explanation:
In this specific scenario, the best source for you to use would be the periodicals. Periodical Literature is a category of serial publications that get released as a new edition on a regular schedule, such as a magazine, newsletters, academic journals, and yearbooks. Some real-life examples include Sports Illustrated, Discovery, or even Time Magazine. These periodical literary sources all provide up to date data on any topic that is needed.
