Answer:
WWII; Manhattan Project.
Explanation:
Computer simulation refers to a mathematical model designed and developed to predict the outcome or behavior of a hypothetical or real-life scenario on a computer system, so as to illustrate and understand how the system functions.
Historically, computer simulations were first developed during World War II (WWII) as a part of the Manhattan Project.
For example, SimpleScalar refers to a computer architectural simulating software application or program which was designed and developed by Todd Austin at the University of Wisconsin, Madison, United States of America. It is an open source simulator written with "C" programming language and it's used typically for modelling virtual computer systems having a central processing unit (CPU), memory system parameters (hierarchy), and cache.
Answer:
Use the combination: Ctrl + Alt + C to get the copyright symbol
Explanation:
<em>Keyboard shortcuts</em> are single or combination of several keys to carry out a specific action. This action may vary according to application programs or operating systems.
Some generic examples of keyboard combinations include:
- Ctrl + C to copy selected objects,
- Ctrl + V to paste copied objects
- Ctrl + N to open a new document or browsing window
- Ctrl + O to open a saved file.
Keyboard shortcuts are a blessing to users for the following reasons:
- Saves time: Imagine dragging a mouse to highlight a document of about 500 pages, what a waste of time right? Ctrl + A will do all that in about a second or two. Using keyboard shortcuts and key combination saves the user a lot of time.
- Efficiency: Since the time spent is greatly reduced, the user becomes more efficient because jobs are carried out faster, more grounds are covered making the user more efficient.
- Multi-tasking: Moving through multiple open windows and tasks with speed requires the use of keyboard shortcuts and combinations. Imagine that you are using a Windows Operating System, you are running an analysis on your browser and it requires you to constantly check it out and you have to finish typing this document on Microsoft Word and you constantly want to ensure that your music player is playing the right song, navigating through this programs using the mouse will just be tiring and may be forced to just stick with a particular application, but with just the Alt + Tab key, you can navigate these applications with ease.
In Office Word 2013, combining the <em>Ctrl + Alt + C</em> will create the copyright symbol in seconds.
