Answer:
The exposure time was vastly too long to be intended for practical use by photographers.
Explanation:
"The very first daguerreotype cameras could not be used for portraiture, as the exposure time required would have been too long. The cameras were fitted with Chevalier lenses which were 'slow' (about f/14). They projected a sharp and undistorted but dim image onto the plate."
Explain basic anatomy of computers.
Explanation:
A computer system can be divided into two components which are responsible for providing the mechanisms to input and output data, to manipulate and process data, and to electronically control the various input, output, and their storage. ... They are known as hardware and software.

Predicting and controlling the social impact of technology, both anticipating new technologies and their social and environment implications and the consequences of ever- increasing scale of application of older technologies is one form of contribution of:
Select one:
A. Science to technology
B. Invention to innovation
C. Innovation to invention
D. Technology to science
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.
Explanation:
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
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.
When it comes to memory, why is it important to have enough storage space on a hard drive when using many RAM intensive programs?
Answer:
Memory and storage are important concepts to master in Information Technology. ... This type of memory is volatile which means that the actual data disappears when the computer loses power. Because memory needs to be much faster than storage, it is rather more expensive than storage per GB.
Explanation:
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.
Why are visually interesting effects, such as WordArt, to be used sparingly?

Answer:
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.
