8 0

The only medium that was used for the dissemination of information during the earliest stages of human history is: C. the human body.

Information sharing is an integral part of human life because no human is able to live comfortably in isolation without the need to share or receive messages from others through a particular medium, especially for awareness, growth, development and proper decision making.

Prior to the medieval period, which is the earliest stage of human history, the human body serve extensively as the only medium that was used for the dissemination of information from one person to another.

This ultimately implies that, various symbols, signs and objects that were mutually understandable to the people were drawn or written on human body, so as to serve as a medium during the process of communication.

A DBMS acts as a conduit between the database and the applications that will use it, enabling users to access, modify, and control how the data is arranged and optimized.

Data points that are connected to one another are stored and accessible in a relational database, which is a form of database. The relational model, an easy-to-understand method of representing data in tables, is the foundation of relational databases. Data items are requested from the database by application programs, which are created using a combination of the DBMS's data manipulation language and a traditional programming language. The DBMS locates and provides the data elements requested by the application programs.

Suppose you have a program P and 90 percent of P can be parallelized, but 10 percent of P is inherently sequential and cannot be

EleoNora [17]

Answer:

Means no matter how many processors you use, speed up never increase from 10 times.

Explanation:

If a problem of size W has a serial component Ws,then performance using parallelism:

Using Amdahl's Law:

Tp = (W - Ws )/ N + Ws

Here, Ws = .1,

W - Ws = .9

Performance Tp = (.9 / N) + .1

---------------------------------------------------------

Speed Up = 1 / ( (.9 / N) + .1)

If N -> infinity, Speed Up <= 10

Means no matter how many processors you use, speed up never increase from 10 times.
