Explain two ways by which the calendar meets or fails to meet the criteria of showing the correct data

gtnhenbr [62]

Answer:

The two ways the calendar meets the criteria of showing the correct date are;

1) The calendar can give dates in the 12 months in a year

2) The calendar can show up to the 31 different days in a month

Explanation:

The two ways in which the calendar meets the criteria of showing the correct date are;

1) The number number of long blocks with 4 different months each = Three

Therefore, the total number of months the blocks can hold = 3 × 4 months = 12 months = The number of months in a year

2) The number of faces on each dice = 6 faces

The number of dice = 2 dice

The total number of faces = 12

The number of identical faces = 2 (11th and 22nd of the month)

The number of unique faces = 10

The number of combinations of the dices = ₁₀C₂ = 45

The number of combination of faces required to show = 1 to 31 = 31 combination

Therefore, there are adequate combinations on the dice to show all the dates of month

What kind of printer is used with multipart forms such as those with point of sale machines?A) dot-matrixB) daisy-wheelC) inkjet

ivanzaharov [21]

Answer:

The answer is "Option A".

Explanation:

The Dot matrix printer is also known as an impact matrix printer. It is a multi-part form printer because it prints data on paper. This printer uses a hammer and a ribbon printer, that shapes pictures from dots. and other options are not correct, that can be described as follows:

In option B, daisy-wheel printer prints data on printer only one side that's it is not correct.
In option C, the Inkjet printer is capable to print data in multi-part forms, but this printer does not data in continuous forms.
In option D, the color printer allows you to print data in color format like images, graphs, and banner. It prints data only on one side, that's why it is not correct.

What technique involves graphical methods and nontechnical language that represent the system at various stages of development a

Mnenie [13.5K]

Answer:

The answer to this question this "modeling".

Explanation:

In this question, the answer is modeling because in system design we use System Analysis and Design(SAD). It is the most important subject in any software design like a mobile application, website, web pages, etc. In this subject, there is an important topic that is SDLC. The term SDLC stands for systems development life cycle or it is also known as the software development life cycle. It is a conceptual modeling used in project management that describes the stages involves the information for system development project. It maintenance the complete application. SDLC applied to technical and non-technical systems. In the SDLC many phases can be given as:

Requirement gathering and analysis:

In this phase, all the relevant information is collected from the customer to develop a product as their expectation.

Design:

In the design phase, the requirement gather by the software requirements specification (SRS) in a document that is used for software architecture.

Implementation or coding:

After completing the design phase we implement/coding in that section like User input validation, admin work, payment management, etc.

Testing:

In this section, we test all the things in software before hand over to the customer.

Deployment:

In this section after completing the testing successfully. it goes to the deployment section in this section production environment or User Acceptance testing is done depending on the customer expectation.

Maintenance:

In the maintenance section when the product is hand over customer and in future if any issue comes up and needs to be fixed or there is any Up-gradation is needed So it is done by the developers.

In computer science, any development is done on modules. So the answer to this question is modeling.

What are the differences between a trap (aka software interrupt) and an interrupt (hardware interrupt)? What is the use of each

Marta_Voda [28]

Answer:

Trap is a software interrupt that occurs when there is a system call, while hardware interrupt occurs when a hardware component needs urgent attention.

Explanation:

Interrupt is an input signal that disrupt the activities of a computer system, giving immediate attention to a hardware or software request.

In trap interrupt, the system activities are stop for a routine kernel mode operation, since it has a higher priority than the user mode. At the end of the interrupt, it switches control to the user mode.

The hardware interrupt is a signal from hardware devices like the input/output devices, storage and even peripheral devices that draws an immediate attention of the processor, stopping and saving other activities and executing the event with an interrupt handler.
