1. The answer is Command-line base

MS-DOS is a single user, single tasking OS that use a command line interface. MS –DOS is the perfect example of a command line interface. CLI is a text based interface used by operating systems and software and performs particular tasks by entering commands. Unlike the GUI (Graphical User Interface), the CLI uses a very easy mechanism which is not user friendly.

2. The answer is carry electrical current

Transistors are semiconductor devices used to control the flow of electricity in circuits. They contain three layers of silicon that are used to amplify or switch electric currents. They are very fundamental in modern electronic devices and are considered one of the greatest inventions in modern history. In small quantities, transistors are used to make simple switches and digital logic. In huge quantities, transistors are interconnected and combined into small chips that create complex ICs, computer memories, and processors.

3. The answer is True

A peripheral device such as a keyboard, a mouse, or a printer is a hardware input or output device that gives the computer additional functionalities and serve as an auxiliary computer device. They are commonly known as I/O devices because they provide input and output information for the computer.

4. The answer is A: Interacts with or sends data to the computer

A peripheral device as mentioned above is used to input information into and get it out of the computer. In addition, an input device sends data, information, or instructions to the computer. Examples of input devices include, keyboard, mouse, graphics tablet, game controller, read only memory, and many more.

5. The answer is doc .

Doc file extension is the general default binary and XML-based format for Word 97 all the way to Word 2019. This file extension can contain formatted texts, tables, images, page formatting, and graphs. Depending on the versions of the Microsoft Word, the standards for the DOC extension change slightly from .doc to .docx

Todd insisted on having an image to go with every slide. Is this good or bad?

valentina_108 [34]

Answer:

Yes, Its a good idea but depends upon type of image. Like adding a logo to all the slides at top left corner is not just good but a must for all as well, when we are preparing official documents. However, other images when decided to be repeated must convey the correct intent in each page. If this is not the case, you need to avoid it. Intent is the most important aspect certainly. For rest see explanation.

Explanation:

Yes, and as mentioned above adding logo and other images meaningfully, and with correct intent is a good idea.

However, images must not be blurred, tiny or stretched. Also proper cropping is a must. The border should be solid as well. And when selecting a lot of images, the images must convey the correct meaning together. Moreover, the aspect ratio after stretching must be same as the original. You can do this in PowerPoint by going to format > crop > fill.

Ensure that watermarks are not revealed. Buy them rather than copy from somewhere for better outcome. And never amputate your readers with a headache creating backgrounds. You will loose readers then. The clip arts must be used in right number, and not a lot of them certainly.

Ensure both text and images are in correct ratios. Avoid using more than 2 images per slide.

There are generally two ways of implementing dynamic programming solutions to problems, which have equal asymptotic time complex

san4es73 [151]

Answer:

1) Bottom-up

2) Top-down

Explanation:

In general dynamic programming is a divide and conquer strategy which can be implemented using bottom up approach or top down approach.

Bottom-up approach in dynamic programming will solve a relatively simple sub-problem first and then use the solution to build and arrive at solutions to a bigger sub-problem.

Top down approach is reversed to bottom-up approach and is also known as Memoization Method. Instead of solving a problem started from the base state sub-problem, the top down approach break a problem into a smaller problems from the top most destination state until it reaches the bottom most base state.

A variable must have its type declared but it is not required to be initialized prior to first use.

AnnZ [28]

Answer:

a) TRUE.

Explanation:

The statement is true.We can declare a variable but not initialize it there we can initialize it afterwards when we want to use.On declaring the variable type it tells the compiler to reserve the memory according to the size required for the data type.When we initialize the memory is allocated to that variable.
