How many dial-up input-output (I/O) ports are needed for a computer center to support 40 users with a blocking probability limit of 5%? Assume each user averages four calls per day with an average session duration of 30 min. If three users remain connected all day, what is the grade of service for the remaining 37 users? wax thinke in

When the 8088 does a reset it goes to the physical address ________ H and begins executing from that memory location.

Q.1) What is the type of PCI transaction diagram? Redraw the timing when the IRDY# and TRDY# is ready from cycle 2 to end of transaction and explained the function of each signals appear in diagram.

A. What is the advantage of circuit switching over packet switching? Select one: a. Will not require connection set-up in advance b. Packets will be required to queue, making traffic more orderly c. Ensures that there is no contention for the use of resources d. Ensures that the resource capacity is maximized ===================================== B. Evaluate this statement. Considering the different delays in a packet switching network, a transmitted packet will reach its destination. Select one: a. Always true b. False c. Not enough information is given d. Sometimes true

QUESTION 36 The 8088 physical address is bits wide. [type the number only]

I need some help with the image provided. This is for microcontroller and embeded system. it seems is related to interrupts and it is providing some logical gates. Can someone explain wherever is happening in the image. I only need to grap the concepts nothing really technical

Design a security system for a smart home that includes a door and a window sensor. The system should trigger an alarm when a door or the window is opened while the security system is active. Your task is to design an ASIC based system that efficiently monitors the state of the door and window sensors and activates the alarm when necessary. You should consider inputs for the security system state (activated, deactivated) and the open/closed state of each sensor for door and window, and the output for the alarm activation. a) Provide gate level implementation with minimum possible number of gates. Use standard minimization techniques used in digital design to reduce the gates count. b) Develop the most efficient SCMOS transistor switch level schematic for the minimized logic obtained from part A. c) Develop the most efficient stick diagram for the layout in part B, and estimate the area in micron square d) Develop Standard cell layout and find the density of the logic e) Produce routing…

2. In the NUCLEO-F401RE board, user LED (green one) is connected to PA.5(GPIOA and pin 5), the Bule user button is connected to PC.13(GPIOC and pin 13). Using this information, write a sequence of C instructions that would do the following. a. Configure the GPIO pin connected to the Green LED as an output. b. Write a 1 to the pin to turn on the Green LED by writing to the output data register (ODR) of that GPIO port. c. Configure the GPIO pin connected to the push button as an input. d. Read the state of the button by reading the input data register (IDR) of that GPIO port. Notes: provide the segments of your codes. You do not need to provide an entire declaration of GPIOX address and related registers struct of the GPIO (we assume they are already declared). For example, if you want to read the input data for pin 15 of GPIOC, the following code is sufficient: int a GPIOC->IDR & (1 << 15);

Assuming that a 5-bit ADC channel accepts analog input ranging from 0 tos volts, determine the following a) Number of quantization levels b) Step size of quantizer or resolution ) Quantization level when the analog voltage is 3.2 volts dj Binary code produced by the ADC e) Quantization error.
