The symbol that goes before myvar if it is supposed to refer to the address of myvar is & (ampersand). Therefore, the code for this expression will be Foo = &myvar.

In programming, an address refers to the memory location of a variable. The & symbol, called the address-of operator, is used to obtain the memory address of a variable in C and C++ programming languages.

In the given code expression "Foo = &myvar", the ampersand symbol '&' before the variable "myvar" will give us the address of "myvar". The address will then be stored in the variable "Foo". This is useful when we want to pass the memory address of a variable to a function or manipulate the value at that memory address directly.

The medium access control protocol require computers to wait a random to prevent collision in shared network.

To ensure  network access and prevent collisions in shared network settings like Ethernet, the Medium Access Control (MAC) protocol uses the random back-off mechanism.

When several computing machines or gadgets endeavor to transfer data at once, it can result in collisions that cause network inefficiencies and compromise the integrity of the transmitted information.

To alleviate this problem, the MAC protocol employs a method of contention in which each device checks for network activity before sending any data. If the network is congested, the device needs to pause for a random duration before making another attempt to transmit.

The utilization of the random back-off mechanism efficiently disperses the retransmission attempts among the devices, thus decreasing the probability of collisions and allowing every device an equitable opportunity to access the network medium.

The ADC is 8-bit, it can only represent 256 discrete levels, which corresponds to a step size of 10 [V] / 256 = 0.039 [V] per level.

Therefore, we need to round the required shift to the nearest multiple of the ADC step size, which is 0.039 [V].

To design the signal-conditioning circuit for interfacing the IC temperature sensor to the 8-bit ADC, we need to consider the sensor output range, the ADC reference voltage, and the desired resolution.

Given information:

IC temperature sensor gain: 10 [mV/°C]

Temperature range: up to 100 [°C]

ADC reference voltage: 10 [V]

To interface the sensor signal to the ADC, we need to scale and shift the sensor output voltage to match the ADC input voltage range. Here's the step-by-step process:

Scaling the sensor output voltage:

Since the sensor gain is 10 [mV/°C], the maximum output voltage from the sensor for 100 [°C] will be:

Maximum Sensor Output Voltage = 100 [°C] * 10 [mV/°C] = 1000 [mV] = 1 [V]

Shifting the sensor output voltage:

The ADC reference voltage is 10 [V], and the ADC has 8-bit resolution, which means it can represent 2^8 = 256 discrete levels.

We need to scale the sensor output voltage to fit within the ADC reference voltage range (0 V to 10 V).

By subtracting the minimum sensor output voltage from the maximum sensor output voltage, we can find the required shift:

Required Shift = ADC Reference Voltage / Number of ADC Levels = 10 [V] / 256 = 0.039 [V]

However, since the ADC is 8-bit, it can only represent 256 discrete levels, which corresponds to a step size of 10 [V] / 256 = 0.039 [V] per level.

Therefore, we need to round the required shift to the nearest multiple of the ADC step size, which is 0.039 [V].

Final signal-conditioning circuit design:

To interface the sensor signal to the ADC, we can use an operational amplifier (op-amp) in a non-inverting amplifier configuration. The op-amp can amplify and shift the sensor output voltage to match the ADC input voltage range.

Let's assume we use an op-amp with a gain of 10. We can calculate the feedback resistor value (Rf) using the following formula:

Gain = 1 + (Rf / R1)

Since we want a gain of 10, we can choose R1 = 1 kΩ and solve for Rf:

10 = 1 + (Rf / 1000)

Rf = 9 kΩ

The op-amp circuit would look like this:

                   +-----------+

     Sensor Output --| Inverting |---- ADC Input

                   | Amplifier |

                        |

               R1 = 1 kΩ |

                        |

                       ---

                        |

                       GND

Temperature resolution:

The ADC has 8-bit resolution, which means it can represent 256 discrete levels. Each level corresponds to a voltage step of 0.039 [V] (as calculated earlier).

The temperature resolution can be determined by dividing the temperature range by the number of ADC levels:

Temperature Resolution = Temperature Range / Number of ADC Levels = 100 [°C] / 256 = 0.391 [°C]

Therefore, the temperature resolution achieved with this setup is approximately 0.391 [°C] per step.

Please note that this is a simplified design and additional considerations, such as noise, linearity, and power supply requirements, should be taken into account in a practical implementation. It is always recommended to consult datasheets and application notes for the specific components used in the circuit and to simulate the circuit using software tools to verify its performance.

1. A function can use variables as parameters.

2. A function can have more than one parameter.

3. The definition of a function must come before where the function is used.

Explanation:

The definition of a function can come before or after it is used - I am pretty sure it cannot be placed after the function is being used. It should always come before it is used, so this statement is false.

A function can use variables as parameters - this is true, variables are just labels to hold data.

A function can have more than one parameter - this is true.

A function must have a return value - functions do not always have to return values. It could simply print, so this statement is false.

The definition of a function must come before where the function is used - As said earlier, the definition of functions must come before it is used/called. This statement is true.

The default file system used by Windows 7 is NTFS (New Technology File System).

Option C. NTFS is correct.

The default file system used by Windows 7 is NTFS (New Technology File System).

NTFS was introduced by Microsoft in 1993 as an improvement over the older FAT (File Allocation Table) file system. NTFS is a more advanced and robust file system that supports larger files and provides better security and data reliability.

NTFS offers several advantages over FAT, such as support for larger file sizes, improved performance, better security, and more efficient use of disk space.

With NTFS, you can store files larger than 4GB, which is the maximum file size supported by FAT32. This is especially useful for users who work with large media files, such as videos, images, and audio files.

Another advantage of NTFS is its support for advanced security features such as file and folder permissions, encryption, and auditing.

This allows users to set permissions on individual files and folders, control who can access them, and track changes made to them.

NTFS also supports journaling, which means that file system changes are logged to a journal file before they are written to disk.

This helps prevent data loss in case of a power failure or system crash.

In summary, NTFS is the default file system used by Windows 7, and it offers several advantages over the older FAT file system.

NTFS provides better performance, larger file size support, enhanced security, and more efficient use of disk space, making it the preferred choice for modern Windows operating systems.

Explanation

The HCA must install a new $1.4 million computer to track patient records in its multiple service areas. It plans to use the computer for only three years, at which time a brand new system will be acquired that will handle both billing and patient records.

It can obtain a 10% bank loan to buy the computer or it can lease the computer for three years.The initial outlay in case of leasing the computer would be the present value of the payment stream; the final payment is paid at the end of Year 3, so it is discounted three years. Since the lease payment comes at the end of the year, an annuity due factor will be applied.

Using Excel to calculate the present value of lease payment at 10% rate, we get the present value of lease payments to be $1,129,192.98.Using MACRS allowances and marginal tax rate, we can calculate the tax savings associated with buying the computer instead of leasing. With the purchase of the computer,

the MACRS tax savings in Years 1-3 will be $477,320. Using the after-tax salvage value, the company’s net outlay is $782,802.Using these values, we can calculate the Net Advantage to Leasing (NAL)

We see that the NAL is -$277,171.88, indicating that it would be cheaper to purchase the computer instead of leasing it.IRRIRR = 14.12%.
