a particular variety of database that works by connecting tables to each other. It is the most popular form of database and the type we will discuss most in this class.
Answer:
Relational Database
Explanation:
Relational Database is the type of database in which data is stored and presented in the form of tables and it is used to access, manipulate and manage data.Table is also called a relation. It consists of rows and columns where rows represent a record of data and columns represent the attributes of the data.Every table has a primary key which uniquely identifies a row in a table and a foreign key is used to establish relationships among tables.In relational database domain is used to define specify the possible values that an attribute can have.Constraints can also be applied to the values of the attributes in the table.There are many advantages of a relational database. It can organize and manage bulk of information. It is easy to add or delete data in the relational database according to the change in requirements.Relational database ensures the consistency and integrity of data when many users obtain the same database at same time by using concurrency control methods.It ensures security by limiting access rights to the data.It also eliminates data redundancy and dependency using normalization technique which ensures data integrity and accuracy.In a relational database, the link between two tables by a primary key and a foreign key is known as what?
Answer:
Relationship is the correct answer for the above question
Explanation:
When there is a normalization in any table then it is divided into two or more tables. It will help the user to make it easy in access. So when the two tables are made by one table then there is a primary key for the first table and the foreign key for the second table which is used to identify the data of the table. The primary key is used to identify the data of its table and the matching value of the primary key and foreign key is used to identify the data of the second table which makes a relation on the first and the second table.The above question asks about the link between tables where the primary key and foreign key is used and that link is known as relation because it is made up of one table to overcome the problem of normalization. So the answer is the relationship.Tikenya was responsible for creating the PowerPoint presentation for the group project. When it was complete, she wanted to email it to all the group members, but her email service told her the file was too large. She compressed it and was then able to send it. How were the other members able to then see the PowerPoint presentation?
Answer:
They had to unzip or extract the zipped/ compressed presentation to see it.
Explanation:
Compressed file or a zip file contains a large file or more than one files that are packed or enclosed that large file or several files into a file or a folder. The compressed file or folder takes less space than the actual large file or set of files. Just as in this scenario the presentation file was larger than the size of what an email file should be. So Tikenya had to compress the file in order to email it to other members.The other members can open the PowerPoint presentation by following any of the below mentioned methods:In Windows to open a compressed file, right click on that file and select Extract All option.File can also be seen by opening that file or folder and dragging that file or folder from the zipped folder to a new location. In Windows this will automatically extract the files.This file can also be opened using a software like WinZip. Download WinZip. Then download the file which is sent in email and double click on that file which will open WinZip wizard dialogue box. Clicking that presentation file from the dialogue box will open another dialogue box confirming the opening of that file. By clicking on OK the presentation file will be opened and can be viewed now.If an additional term relates to payment, quality, quantity, price, time, and place of delivery, the CISG considers the added terms as material alterations. a.

Noah is saving his Excel spreadsheet as shown.
What will be the file name?
DiverseNames.xls
DiverseNames.xml
DiverseNames.htm
DiverseNames.pdf
Final answer:
The likely file name for Noah's saved Excel spreadsheet is DiverseNames.xls, as this is a common format for Excel workbooks.
Explanation:
When Noah is saving his Excel spreadsheet, the file name depicts the format in which the file will be saved. Common formats for Excel include .xls or .xlsx for Excel workbooks. Since none of the other options provided (.xml, .htm, .pdf) refer to standard Excel workbook formats, DiverseNames.xls is the most likely file name if Noah is saving a standard Excel spreadsheet.
If Noah wanted to save the spreadsheet in a format viewable in a web browser, then DiverseNames.htm (HTML format) would be a correct choice, but DiverseNames.xml could also be possible if he is saving in XML Data format. DiverseNames.pdf would be the file name if he were exporting his spreadsheet to a PDF document, which would not be editable like a spreadsheet but would maintain the formatting when viewed on different devices.

A certain computer game is played between a human player and a computer-controlled player. Every time the computer-controlled player has a turn, the game runs slowly because the computer evaluates all potential moves and selects the best one. Which of the following best describes the possibility of improving the running speed of the game?A The game's running speed can only be improved if the game is played between two human players instead of with the computer-controlled player.B The game's running speed might be improved by using a process that finds approximate solutions every time the computer-controlled player has a turn.C The game's running speed cannot be improved because computers can only be programmed to find the best possible solution.D The game's running speed cannot be improved because the game is an example of an algorithm that does not run in a reasonable time.
Answer:
B The game's running speed might be improved by using a process that finds approximate solutions every time the computer-controlled player has a turn.
Explanation:
Even though the moves are not the perfect ones, the algorithm of the game can be written in a way that it can solve the problems and play faster.
Let's see the problems in other options.
A -> The only way is not replacing the computer with a human because, we know that computers can play faster than a human when the algorithm is written well.
C -> Computers cannot only be programmed to find the best possible solution. They can be programmed how the programmer wants them to behave.
D -> Since we do not know anything about the game, we cannot say anything about the algorithm runtime.

Although the traditional model of software acquisition still accounts for more software acquisition, a new model, called ________, is changing the picture dramatically.A. Hardware as a HelpB. Software as a ServiceC. Processing as a ProductD. Storage as a Solution
Answer:
Option B Software as a Service
Explanation:
Software as a Service (SaaS) is a new software acquisition model. SaaS is based on a subscription license instead of perpetual license. The software is hosted by software provider and the user is required to use a client software or web browser to access and use the software. User pays for the service (software itself) they use on regular basis which can be monthly or yearly.
SaaS offers always up-to-date software solution to the user and the software can be accessed from any machine at any place. Apart from the subscription fee, user is not required to pay additional cost for license renewal or updating software. SaaS provides a cheaper and economic cost of software acquisition.

Using the __________ option, you can change the state of a model back to where a particular feature or features weren`t yet created.
Answer:
Rollback.
Explanation:
Rollback means to restore something to its previous state.In database rollback operation is used to restore the db to a previous state i.e. it will go back to its previous state.This command is used when you perform some incorrect operation on the database mistakenly which might result in affecting the consistency and integrity of data.Rollback option can be used to cancel or undo a single or a set of transactions to return the database to its previous state. It returns the database into the last committed state.Rollback can also be used in case of system or server crashes. For example a system crashes or a power failure, this option will roll back or cancel the processes or transactions that were active during that system crash. So in this way the rollback option restores the database in a consistent state.For example, as we know that we can perform certain operations on data stored in a database such as insert, delete, update etc. So lets say we deleted some records of data from a database using DELETE operation but then we change our mind and use ROLLBACK command which will restore the database into its previous state and delete operation will not affect the records.A network administrator is planning redundant devices and cabling in a switched network to support high availability. Which benefit will implementing the Spanning Tree Protocol provide to this design?
Answer:
Redundant paths can be available without causing logical Layer 2 loops.
Explanation:
Spanning Tree Protocol is used to allow redundancy in the Layer 2 switched networks without creating cycles/circles also called loops. These loops are called physical loops. When two parts of the switched network are connected via two or more Layer 2 switches this result in a loop. This affects the performance of the network as the result of broadcast packets flooding. STP puts one port of the switch to forward mode and the rest of the ports within the same part of the network to the blocking mode to avoid broadcast packet flooding. STP puts all the ports that are allowing redundant paths to block mode and the one port that is left after this is placed in forward mode.Spanning Tree Algorithm is used by STP to determine the optimal path of switch to the network.Bridge Protocol Data Units are used to share the information about the optimal path determined by the spanning tree algorithm with other switches.This information helps STP to eliminate the redundant paths.So this is how STP tracks all the links in the switched network and eliminates redundant loops by allowing only one active path to the destination while blocking all other paths.____ is a systems development technique that produces a graphical representation of a concept or process that systems developers can analyze, test, and modify.
A. Prototyping
B. Rapid application development
C. Scrum
D. Modeling
Answer:
D. Modeling
Explanation:
Modeling: It is a graphical representation, of a concept or system, technique used by software developer to analyze, test, and modify that system or concept.
Computer aided designs and many other system development techniques develop a prototype of solution to a particular problem, which could be tested and analyzed. These process is called Modeling.
Models are very useful in solution development and they serve as a tentative or virtual solution to the problem at hand. The fact they models can be tested, and then modified in areas where they are lacking makes them ideal prototype to reaching a conclusive solution.Hence, the missing phrase is modeling.
