Explanation:
The POS or point of service is a device that allows the purchase of product from a commercial store to be done wirelessly and cashless.

The answer if defiantly B. Story
Answer:
coding phase
testing/debugging phase
Explanation:
During the coding phase they will write the actual code which creates the functionality/program which is added to the software. This phase comes after the dev team designs the algorithm and creates a flow chart of the algorithm. This flow chart is what is used to create the code itself. After the code is complete then the dev team will go into the testing/debugging phase where they will test the program with different test cases. If any bugs/errors are found they will return to the code and implement changes to fix these errors.
Answer:
They are the cardinality ratio and participation constraints.
Explanation:
The Cardinality Ratio: This is for the binary relationship that specifies the max number of instances of relationships in which an entry can take part in. As an example, the Student Of binary relationship form, School: Student, the cardinality ratio of this is 1: N. and that means each of the schools can be mapped to any number of students, however, one student can be mapped to only one school. And various possible cardinality ratios for various types of binary relationships can be 1: N, N:1, 1:1, and M: N.
Participation constraint: This stipulates that an entity being be contingent upon another entity through relationship form. And it stipulates the least figure of instances of relationship which each of the entity can indulge in, and is often termed as least cardinality constraint. And we have participation types: partial and total.
Explanation:
In its most basic form, each node contains:
data, and a reference (in other words, a
link) to the next node in the sequence. A
linked list whose nodes contain two fields:
an integer value and a link to the next node.
The last node is linked to a terminator used
to signify the end of the list.
