You will want 16 (4 x 16) decoders to match the 256 outputs. In other words, you will need 16 times 4 inputs, or 64, but you only have 8 inputs available.
A combinational circuit made of logic gates is a decoder. It is the encoder's opposite. A set of digital input signals is converted into an equivalent decimal code of the output by a decoder circuit. A decoder produces 2n outputs for every 'n' inputs. In this article, we'll talk about designing a circuit for a 4 to 16 decoder utilizing a 3 to 8 decoder.
A combinational circuit known as an encoder converts a group of signals into a code. An encoder circuit produces "n" outputs for "2n" inputs.
By combining two or more lesser combinational circuits, a decoder circuit of the higher combination is created. Two 3 to 8 decoder circuits or three 2 to 4 decoder circuits can be used to create a 4 to 16 decoder circuit.

Answer:
In order to keep track of all conditional formatting used in a worksheet, we use the manage rules menu command under conditional formatting.
Explanation:
Conditional formatting can help make patterns and trends in your data more apparent.
What is the use of conditional formatting?
Conditional formatting makes it easy to highlight certain values or make particular cells easy to identify. This changes the appearance of a cell range based on a condition (or criteria). You can use conditional formatting to highlight cells that contain values that meet a certain condition. To use it, you create rules that determine the format of cells based on their values, such as the following monthly temperature data with cell colors tied to cell values. They are grouped into three categories: Data Bars are horizontal bars added to each cell, much like a bar graph. Color Scales change the color of each cell based on its value. Each color scale uses a two- or three-color gradient. Conditional formatting hence enables you to apply special formatting to cells in your spreadsheet that meet certain criteria.

suppose there is a 1 gbps microwave link between a geostationary satellite and its base station on earth. every minute the satellite takes a digital photo and sends it to the base station. assume a propagation speed of 2.4 x 10^8 m/s and the distance between satellite and station is 48 * 10^3 km. what is the maximum number of bits on the network at any instance of time?
Answer:
At a time the maximum number of bits is 1600000000
Explanation:
First, we must work with the same units, changing the distance into meters we have: 1km = 1000m
48*10^3km *1000m equals 48* 10^6m
Formula for Time=Distance/Speed
48*10^⁶m / 240000000 equals 0.2 seconds.
Calculating the number of bits (1GB=8000000000bits)
we have 0.2 sec corresponds to 0.2gb which is equal to 1600000000 bits.

The advantage of encapsulation is it enables changes to implementation without changing a class's contract and causes no consequential changes to other code.
The definition of encapsulation is the grouping of data into a single unit. It is the mechanism that connects the data the code manipulates with the code itself. Encapsulation can also be viewed as a barrier that stops code from the outside of the barrier from accessing the data.
Technically speaking, encapsulation means that a class's variables or data are concealed from all other classes and are only accessible through member functions of the class in which they are stated.
It is also known as a combination of data-hiding and abstraction because, similar to encapsulation, the data in a class is hidden from other classes using the data hiding concept, which is accomplished by making the members or methods of a class private, and the class is exposed to the end-user or the world without providing any details behind implementation.
Encapsulation can be accomplished by writing public methods in the class to set and get the values of variables and declaring all of the class's variables as private. With the setter and getter methods, it is more clearly described.
