What are the useful techniques in program design?
A broad question, with many answers.
When designing a program you can use:
Setting up requirements, possibly in a use-case form ("as a ... I want to ... so that ...")Mapping the verbs and nouns in your requirements to classes and operations Drawing UML diagrams of the subject matterCreating flow charts and sequence diagrams Identify component boundaries with thin interfaces to keep complexity organized and localWhat visual practice provides more information about logical relations when creating an ERD
Answer:
Logical Data Model
Explanation:
An Entity Relationship Diagram (ERD) is a model or a diagram designed to reveal the relationship between various entities such as people, places, objects, and so on within an institution. Entity relationship diagram is also known as Entity relationship model. This model is used to design relational database by various sectors such as education, engineering, business, etc.
ERD is designed using conceptual data model, logical data model, and physical data model.
The visual practice or model that gives more insight into the logical relations among the entity is the logical data model.
The logical data model is used to illustrate more detailed operational and relational data among the entities. It is more detailed than the conceptual data.
So, the correct answer is logical data model.
What is the features of Mark 1
Answer:
Okay:
Mark I was enourmous in size, measuring 8 feet high, 51 feet long and three feet deep. It weighed 5 tons, used 530 miles of wire and 730,000 separate parts. The operation of these parts was powered and synchronized by a long horizontal rotating shaft. A four horsepower engine drives the mechanical parts.
Harvard Mark I, an early protocomputer, built during World War II in the United States. While Vannevar Bush was working on analog computing at the Massachusetts Institute of Technology (MIT), across town Harvard University professor Howard Aiken was working with digital devices for calculation. He had begun to realize in hardware something like the 19th-century English inventor Charles Babbage’s Analytical Engine, which he had read about. Starting in 1937, Aiken laid out detailed plans for a series of four calculating machines of increasing sophistication, based on different technologies, from the largely mechanical Mark I to the electronic Mark IV.

Why would you want to hyperlink objects into your own Google Slides presentation? (Select all that apply.) Select All Correct Responses For extending the learning experience for students. To make sure the presentation is linear So students can use the Slides for review and can go to additional resources outside of the presentation. To make the presentation more graphically appealing
The correct answers are A. For extending the learning experience for students. C. So students can use the Slides for review and can go to additional resources outside of the presentation. D. To make the presentation more graphically appealing
Explanation:
The use of hyperlink objects in presentations means objects such as images, texts, or icons are associated with links or websites students can easily access by clicking on the specific image or element. This might be used in educational contexts to allow students to have a complete learning experience by providing alternative and external sources outside the presentation. For example, if the topic is space hyperlinks to NASA website can be included. This means, hyperlink objects extend learning experiences and provide additional resources (Option A and D).
Besides this, this resource can make a presentation more appealing as links to images, videos, and other visually interesting resources can be included (Option D). However, it also breaks the linearity of the presentation as students will need to move to other websites as they go through the presentation.

Draw a truth table & logic circuit corresponding to the following logic statement
X = 1 if ( ( M is 1 OR N is 1 ) AND ( M is 1 AND N is 1 ) ) OR ( O is NOT 1 )
Answer:
The truth table, as well as the logic circuit of the given statement, is attached below.
Explanation:
Logical gates seem to be the essential building blocks of just about any computerized signal. It becomes a digital device with one or even more inputs and therefore only single output. The arrangement among outputs and inputs would be focused on this kind of logic. Upon that basis, logic gates were already called as AND, NOT, OR gate, etc.
