Answer:
a. engranaje 1 → engranaje 2 → engranaje 3 → engranaje 4
z1 = 10 z2 = 20 z3 =10 z4 = 20
b. n2 = 600 rpm, n3 = 1200 rpm, n4 = 600 rpm
la relacion de transmision = 2
Explanation:
where z1 = 10, z2 = 20, z3 = 10, z4 = 20
and n1 = 1200 rpm
n2 = n1 * z1/z2 = (1200 * 10)/ 20 = 600 rpm
n3 = n2 * z2/z3 = (600 * 20)/ 10 = 1200 rpm
n4 = n3 * z3/z4 = (1200 * 10)/ 20 = 600 rpm
la relacion de transmision = z2/z1 * z3/z2 * z4/z3
= 20/10 * 10/20 * 20/10 = 2 * 0.5 * 2 = 2
Answer:
A. True
Explanation:
DBMS is an acronym for database management system and it can be defined as a collection of software applications that typically enables computer users to create, store, modify, retrieve and manage data or informations in a database. Generally, it allows computer users to efficiently retrieve and manage their data with an appropriate level of security.
Some examples of a database management system (DBMS) are RDBMS, Oracle, SQL server, PostgreSQL, dBASE, Clipper, MySQL, Microsoft Access, etc.
A DBMS commonly receives data update requests from application programs through the Open Database Connectivity ( ODBC ) driver in case of communication with other database management softwares.
Basically, when a database management system (DBMS) receives data update requests from application programs, it simply instructs the operating system installed on a server to provide the requested data or informations.
This can be done in a number of steps.

The publisher tab in the application control allows you to manage the various certificates that are used to sign to binaries. Publisher allow executables of a particular vendor, signed by a security certificate issued
to the vendor by a Certificate Authority. Also, all applications and binary files either added
to or modified on an endpoint that are signed by the certificate are automatically added to
the whitelist.
Answer: The tools which are required to accomplish each step in the data management process are:
1. Cloud Data Management tools.
2. Master Data Management (MDM) tools.
3. Reference Data Management (RDM) tools.
4. ETL tools.
5. Data visualization and analytics tools
Explanation:
Cloud Data Management tools with the help of various API's are able to connect multiples system with their data to the cloud. examples are amazon cloud, google API cloud.
MDM tools are used for creation and maintenance of reference data. example are Profisee
RDM tools is used with the MDM tools and are use to define the businesss processes over the reference data. Examples are Collibra.
ETL tools helps to load data of an organisation to data warehouses after transformation and testing the data pipeline constituting the data from different databases.
Data visualization analytics tools helps to extract and generate report from the big sets of data which can help an organisation to take business decisions.
