Q6) a) How long are Ethernet EUI-48 addresses?

The given statement "The counter reset (RES) instruction, it is always given the same address as the counter it is to reset." is true because the counter reset (RES) instruction is always given the same address as the counter it is to reset.

The RES instruction is used to reset the current value of a counter to its initial value, which is typically set to 0 or another predetermined value. In order to reset a specific counter, the RES instruction must be addressed to the same memory address as the counter. This ensures that the instruction is applied to the correct counter and that it resets the counter to the correct initial value. Therefore, the statement "the counter reset (RES) instruction is always given the same address as the counter it is to reset" is true.

The three regions of a beam profile are the central region, the transition region, and the far field region.

The central region is where the beam is most intense and has the smallest diameter. The transition region is where the beam begins to diverge and its diameter starts to increase. The far field region is where the beam has fully diverged and its diameter reaches a stable size. The size and shape of these regions depend on various factors, such as the wavelength of the beam, the size of the aperture through which it passes, and the distance from the source.

The given statement "A timer delay time equals the value in the ACC multiplied by the time base " is true.

In many electronic systems, timer circuits are used to generate accurate delays. These circuits consist of a counter and a clock source, and the delay time is determined by the count value of the counter and the frequency of the clock. In some cases, the delay time is set by an external signal, while in others, it is determined by the value of a register in the system.

In the case of a timer delay time equaling the value in the ACC (accumulator) multiplied by the time base, this means that the delay time is directly proportional to the value stored in the ACC and the time base. The ACC is a register in the system that stores data temporarily for processing, and the time base is the frequency of the clock used by the timer circuit.

Thus, if the value of the ACC is increased, the delay time will also increase proportionally. Similarly, if the time base frequency is increased, the delay time will decrease proportionally. This relationship is essential in designing and programming accurate timing circuits in electronic systems.

If the airspeed is decreased from 98 knots to 85 knots during a coordinated level 45 degree banked turn, the load factor will remain the same, but the radius of turn will increase.

This is because the load factor is determined by the angle of bank and the airspeed, not the radius of turn. However, since the airspeed has decreased, the radius of turn will increase as the airplane will not be able to maintain the same amount of lift at the slower speed. The slower airspeed will also decrease the rate of turn.

To answer your question, let's first define the terms:

- Airspeed: The speed of an aircraft relative to the surrounding air
- Knots: A unit of speed used in aviation, equal to one nautical mile per hour
- Radius: The distance from the center of a circle to its edge, in this context, the distance from the center of a turn to the aircraft

In a coordinated level 45-degree banked turn, the load factor remains constant because the bank angle doesn't change. However, when the airspeed decreases from 98 knots to 85 knots, the radius of the turn will also decrease. This is because the aircraft will require less horizontal distance to complete the turn at a lower speed.

So, the correct answer is: The load factor will remain the same, but the radius of turn will decrease.

True. When a grounded box is surface-mounted, the receptacle may be grounded to the box by making direct metal-to-metal contact with the device yoke. The grounding terminal of the receptacle should still be connected to the box via an equipment bonding jumper, though.

According to the National Electrical Code (NEC) section 250-146(A), an equipment bonding jumper must be used to connect the grounding terminal of a grounding-type receptacle to a grounded box. This is necessary to provide a low-impedance path for fault current and to ensure proper grounding of the receptacle. However, in cases where the box is surface mounted, direct metal-to-metal contact between the device yoke (the metal frame surrounding the receptacle) and the box is also permitted to ground the receptacle to the box. This is because the surface-mounted box is already grounded due to its connection to the building's electrical system.

DDR (Double Data Rate) SDRAM made significant improvements over regular SDRAM (Synchronous Dynamic Random Access Memory) in terms of memory performance and speed.

The primary advancement is that DDR can transfer data twice per clock cycle, effectively doubling the bandwidth available for data transmission compared to SDRAM.

While SDRAM sends data once per clock cycle (single data rate), DDR sends data on both the rising and falling edges of the clock signal, thus utilizing the full potential of the memory module.

This results in faster data transfer rates and better overall system performance. Additionally, DDR introduced a lower operating voltage of 2.5 volts compared to SDRAM's 3.3 volts, leading to reduced power consumption and less heat generation in computer systems.

In summary, DDR's ability to transfer data twice per clock cycle, its increased bandwidth, and lower power consumption make it a major improvement over regular SDRAM, contributing to enhanced performance in computer systems.

The three-step handshake is a process used to establish a reliable TCP connection between two devices in a network. It involves the following steps:

2. SYN-ACK: Upon receiving the SYN request, the server sends a TCP packet back to the client with both the SYN and ACK (acknowledge) flags set. The server acknowledges the client's initial sequence number and provides its own sequence number for data transmission.

3. ACK: Finally, the client sends another TCP packet to the server with the ACK flag set, acknowledging the server's initial sequence number. This completes the three-step handshake, and a reliable TCP connection is established between the two devices.
