6 NAND gates are needed to construct this line decoder when a 2x4 line decoder with enable is implemented using nand gate only.
What is NAND gate?
The NAND gate is a hybrid of the AND and NOT gates. They are linked in a cascade fashion. It is also known as the Negated And gate. Only when their outputs are high or true does the NAND gate provide a false or low output. The NAND gate is necessary because it is used to implement various types of boolean functions.
The NAND gate has the functional completeness property. The NAND gate's function completeness means that it can be used to implement any type of gate. It functions as an OR, NOR, and AND gate.

Answer:
Actions that Bobbi should take to identify opportunities for online business growth are:
Review competitor websites
Identify a USP
Build a SWOT analysis
Explanation:
The first thing Bobbi should do is to review competitor website.
This will give her information about her competitors the products that they offer, the price of their products, the website layout and structure of the competitors, any strategy they are using to boost their online product sale such as by offering product promotion, discounted price etc.
After reviewing competitor websites, next thing that Bobbi should do is identify a Unique Selling Proposition. Bobbi should identify the unique features, benefits of her products that induce her business to stand out from the competitors. Identify all those unique aspects and factors that make her product different from others.
After identifying USP, Bobbi should now build a Strengths, Weaknesses, Opportunities and Threats (SWOT) analysis. This way she will be able to recognize and understand her website's strengths, distinctive competencies, limitations, opportunities and risks. This will help her to analyse the overall strategic position of her website as well as her business. That will help her create a strategy for the future.
Answer: OSI system is called Open System Interconnection because It provides the collection of protocols for the connection of different system to connect with any dependence on any other system or network.
Explanation: Open system interconnection establishes a connection between the different system for the communication purpose using several protocols and software standards .It has no dependency or any network or other system to do the functioning and works using the seven layers of the OSI architecture.Thus, that is why OSI system known as open system.
Answer:
java: error
C: false
Explanation:
In Java the compiler understand that you are trying to compare an integer (15) with a boolean (10 > 5) this generate the next error:
error: bad operand types for binary operator
In C the compiler convert (15 > 10 > 5) in (15>10) > (10>5) which is equal to TRUE > TRUE, the compiler can also read it as 1 > 1 (since 1 is TRUE and 0 is FALSE). like 1>1 is false then C program return false.
The answer is D, I believe.
