Answer:
A problem is a challenging task or process that needs resources not available to the individual or group responsible for the task.
An example of a business problem is data analysis.
Explanation:
A business enterprise is driven by profit making. Investing in a business opportunity requires or demands for feasibility study. Without the right computer skills, a company dives into various physical forms of survey like giving questionnaires to potential clients.
This form of survey requires a lot of time and money that should be invested in other assets in the company and the data acquired, sometimes is not enough to make long term business decisions.
On the other hand, when a spreed sheet application is used (like microsoft excel) by a business data analyst with big data and data visualization skills, large data could be accessed online and analysed of a fast and efficient descriptive and predictive analysis for long term business decisions.

Explanation:
Step 1: Circuit Designing: you have to address the question what is your proposed circuit going to do (its function).
Step 2: Decide on circuit components that can address each such circuit functions.
Step 3: Decide on the operational specification for the circuit: voltages, currents, frequencies etc.
Step 4: Simulate your circuit to confirm if it works as expected with simulation software such as Multisim.
Answer:
12 bits
Explanation:
With 12 bits you can represent numbers from 0 to 2¹²-1, i.e. 0 to 4095.
To check: with 11 bits you can only represent up to 2047, so that's not enough.
In general, to calculate the number of bits without trial and error, you can take the ²log of the number you want to represent and then round up:
²log(3001) = log(3001)/log(2) ≈ 11.55, rounded up is 12.
This will depend on what the user has set the default working directory to. In order to check for yourself what your default working directory is inside linux, simply log in, click the start button>Click System Tools>LXTerminal. Once in the terminal, you can check your current working directory by typing in "pwd" without the quotation marks. Then, hit enter on your keyboard and the terminal will print your current working directory. I hope this has helped you.
