differentiate between standard and enhanced keyboard(10 diffrences)
Answers
Explanation:
by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.
A standard keyboard typically features a basic layout and functionality, while an enhanced keyboard includes additional features such as multimedia keys, customizable macros, and backlighting options.
The difference between standard and enhanced keyboards are as follows:
1) Key Layout: One of the primary differences between a standard keyboard and an enhanced keyboard is the key layout. A standard keyboard typically follows the traditional QWERTY layout, while an enhanced keyboard may have additional keys or modified key arrangements.
2) Extra Function Keys: Enhanced keyboards often feature additional function keys beyond the standard set found on a standard keyboard. These extra keys may provide quick access to specific functions like media controls, volume adjustment, launching applications, or controlling lighting effects.
3) Multimedia Controls: Enhanced keyboards often include dedicated multimedia controls for managing audio and video playback. These controls allow users to play, pause, stop, or skip tracks without the need to navigate through software interfaces.
4) Macro Keys: Enhanced keyboards may offer programmable macro keys that allow users to assign custom functions or complex sequences of commands to a single key press. This feature is commonly utilized by gamers or power users who require quick access to specific actions or shortcuts.
5) Backlit Keys: Many enhanced keyboards have backlit keys, allowing for improved visibility in low-light environments. These keyboards may offer adjustable backlighting levels or even customizable RGB lighting options for personalization.
6) Touchpad or Trackpad: Some enhanced keyboards include an integrated touchpad or trackpad, similar to those found on laptops. This feature eliminates the need for a separate mouse and provides cursor control directly on the keyboard.
7) Ergonomic Design: Enhanced keyboards often prioritize ergonomics by incorporating features like palm rests, adjustable tilt angles, or split keyboard layouts. These design elements aim to provide increased comfort and reduce the risk of repetitive strain injuries.
8) Connectivity Options: While standard keyboards usually come with a wired USB connection, enhanced keyboards may offer additional connectivity options such as wireless Bluetooth or specialized connectors like USB-C for faster data transfer.
9) Specialized Keys: Enhanced keyboards may have dedicated keys for specific purposes, such as gaming keyboards with keys optimized for gaming actions like WASD movement or mechanical keyboards with specialized switches for tactile feedback.
10) Software Integration: Enhanced keyboards often come with companion software that allows users to customize key functions, lighting effects, and other settings. This software integration provides additional flexibility and personalization options beyond what standard keyboards offer.

Answers
Answer:
19
Explanation:
Without break; statements, the switch "falls through" to the next case. So the code is directed to case 3, which sets total to 10. Then another 3 gets added and another 6, because cases 4 and 8 are also executed. That brings the total to 19.
So, always use a compile rule or code checker that checks your code for missing breaks, because it is hardly ever what you want on purpose.

Answer:
If your mask touches another part of your body that is potentially contaminated with the virus—hair, forehead, hands—and the mask is put over your mouth and nose, you are at risk for infection.
Always be sure to wash your hands before putting your mask on, and once it is in place and you are out in public, don’t keep touching or adjusting it. When you’re not wearing it, don’t leave it around your neck in case there was any type of contamination.

Select one:
A. Science to technology
B. Invention to innovation
C. Innovation to invention
D. Technology to science
Answers
Answer:
This report is a response to General Assembly resolution 72/242, in which the
Commission on Science and Technology for Development is requested, through the
Economic and Social Council, to give due consideration to the impact of key rapid
technological changes on the achievement of the Sustainable Development Goals. The report
contains analysis of the impact of rapid technological change on sustainable development,
especially the consequences for the 2030 Agenda for Sustainable Development’s central
principle of “leaving no one behind”. It presents the opportunities offered by rapid
technological change regarding the achievement and monitoring of the Sustainable
Development Goals across the various economic, social and environmental dimensions.
It discusses the transformative and disruptive potential of rapid technological changes,
including economic, social and normative considerations. In the report, it is highlighted that,
without appropriate science, technology and innovation policies, technologies, be they old
or new, are unlikely to deliver progress regarding global development. Such progress
requires an environment that nurtures learning and innovation to build and manage effective
innovation systems. In this context, the report presents examples of national strategies and
policies for rapid technological change and takes stock of regional, international and multistakeholder cooperation. In addition to national and international policies, the report also
calls for the international community to continue to discuss how international technology
assessment and foresight, as well as consensus building on normative guidelines, can shape
the developmental potential of rapid technological change. It concludes with suggestions for
Member States and the international community.

Consider the following statements regarding computer programs A - Variables can contain different values at different times.B - Reserved words of a programming language can be used as variable names in that languageWhich of the following is true with respect to the above? * O Only A is correct Only B is correct Both A and B are incorrect Both A and B are correot
Answers
Answer:
The answer is: Only A is correct.
Explanation:
Variables in a program can assume different values at different times, and the program can then produce different results, depending on circumstances, so A is correct.
In a computer language, a reserved word (also known as a reserved identifier) is a word that cannot be used as an identifier, such as the name of a variable, function, or label – it is "reserved from use". This is a syntactic definition, and a reserved word may have no meaning. So, B is incorrect.
Hence, the answer is: Only A is correct.

Write a complete method to create an array of random integers. The method takes in three integer parameters: the array size, the lower bound, and the upper bound. The method also takes in a boolean parameter. The method creates and returns an integer array of the specified size that contains random numbers between and lower and upper bound. If the boolean parameter is true, the upper bound is inclusive. If the boolean parameter is false, the upper bound is not inclusive (meaning it is exclusive). Note the lower bound is always inclusive. If any of the parameters are invalid, null is returned.

Microsoft PowerPoint is a popular presentation application that is widely used across many mediums. Maybe you’ve used it to read presentations from conferences or perhaps you’ve explored its basic functions, but have you ever considered its true impact and potential?
As a JAWS user, the benefits of creating visually appealing PowerPoint presentations might not be immediately evident, but the use of images, audio and graphics to convey an idea can significantly impact your audience. Here are 4 reasons to incorporate powerful visuals into your next presentation.
Explanation:
As a presenter, you need to grab the attention of your audience from the very beginning. While your words are certainly important, those who can see the presentation will need more to become fully engaged.
Think of it as showing rather than telling. You are literally creating a balance by illustrating the text points in your slides to convey a message, and what better way to do this than through powerful pictures, videos and graphics to pique their interest.
As a non-visual user, you might have difficulty choosing images. If so, don’t hesitate to consult with sighted individuals to find the right visuals. Your slides will be more compelling and memorable as a result.
