Transport Layer:
Transport layer is used for transferring the data or messages between the nodes and the devices. The data is sent in the form of blocks or segments. It is used to establish the end-to-end connection between the source and the destination.
Network Layer:
Network layer is provides the path in which the data packets are transferred from the source to the destination. It also helps in converting the logical or IP address to physical or Media Access Control (MAC) address.
Internet Protocol:
Internet protocol is a process or protocol in which data is transferred between the computer systems through internet. Each computer system has its own IP address to send or receive the required data. It consists of five different layers namely, application layer, transport layer, network layer, link layer and physical layer.
Datagram:
- In networking, a datagram is a transferring unit which is used to transfer the data from a source to the destination and it doesn’t provide guaranteed service.
- It includes fragmentation process which is defined as the division of the data packet into small one when the data packets are larger than the maximum length of a particular system.

(Hint: From a microprocessor design perspective, identify the values that are fixed in the power computation equation and the parameter that varies with different programs.) Also, provide a specific example where Turbo Mode would be more beneficial. Given: Static power, Pstatic = 5 W • Dynamic power for Base Frequency Mode, Pdynamic_base 2 x 109 Hz= 100 W aCVasefbase = 0.5 × 100 × 10−⁹ F × (1 V)² × • Dynamic power for Turbo Mode, Pdynamic_turbo = αCV turbofturbo = 0.5 × 100 × 10−9 F × (1.2 V)² × 3 × 109 Hz = 216 Warrow_forwardREAD THE ACTUAL INSTRUCTIONSIF NOT QUALIFIED, PASS THE QUESTION ON TO SOMEONE WHO ISDO NOT USE CHATGPT, IT WILL MESS UP THE PROBLEM IN AN OBVIOUS WAY AND YOU WILL BE REPORTEDarrow_forward

- Given a microprocessor with the following specifications and a program consisting of 60 billion instructions, calculate the energy consumption and efficiency for each operating mode. Base Frequency Mode: 2 GHz at 1 V • Turbo Mode: 3 GHz at 1.2 V • CPI = 2.5 • Static Power (Pstatic): 5 Watts ⚫ Dynamic Power Metrics - a = 0.5 (Activity Factor) - C=100nF (Capacitance) Show the detailed calculations for: (1) the wall clock runtime of the program in both modes, and show the speedup of Turbo Mode compared to Base Mode; (2) the total power consumption; and (3) the energy consumption. (Hint: To obtain the energy consumption, you will first need to compute the metrics for items (1) and (2).)arrow_forwardIf X is uniformly distributed over (0, 1) and Y is exponentially distributed with parameter A = 1, and X and Y are independent, find the pdf of Z = X + Y.arrow_forwardThe joint density function of X and Y is given by f(x, y) = xe¯¯x(4+1), ; x > 0, y > 0. a.
