Answer:

Logical Data Model

Explanation:

An Entity Relationship Diagram (ERD) is a model or a diagram designed to reveal the relationship between various entities such as people, places, objects, and so on within an institution. Entity relationship diagram is also known as Entity relationship model. This model is used to design relational database by various sectors such as education, engineering, business, etc.

ERD is designed using conceptual data model, logical data model, and physical data model.

The visual practice or model that gives more insight into the logical relations among the entity is the logical data model.

The logical data model is used to illustrate more detailed operational and relational data among the entities. It is more detailed than the conceptual data.

So, the correct answer is logical data model.

If you create and invoke a recursive function without accounting for a base case, what can go wrong?

oksian1 [2.3K]

Every recursive function should have an exit criterion (=handling the base case) to exit the recursion.

Without it, it wil recurse forever, until system resources run out (typically the call stack will overflow and your program will crash).

Leo noticed that attackers have breached his wireless network. They seem to have used a brute-force attack on the WiFi protected

kakasveta [241]

Answer:

It is called a WPS brutal force attack.

Explanation:

Wired and wireless networks are both susceptible to attacks. The wired network, the advantage as a cable connection, is more secure than wireless networks, but wireless network also have security measures like the wifi protected set up (WPS).

WPS is used to connect to a network without passphrase, but with a key combination or a PIN.

Brutal force attacks are used on WPS to forcefully generate the PIN, using a third party software.

Answer: Provided in the explanation section

Explanation:

A YMS acts an interface between a WMS and TMS.The evaluation system with the key performance indicators are mentioned in the table below.

NOTE: The analysis follows in this order given below

Metric
Description
Comments

Metric 1

Trailer utilization

Description :This captures the status of the trailer whether it is in the yard or is in transit

Comments : Helps in measuring the trailer productivity on a daily ,weekly or monthly basis

Metric 2

Driver utilization

Description : This captures the status of the driver whether the driver is in the yard or is in transit

Comments : Helps in measuring the driver productivity on a periodic basis

Metric 3

Trailer sequence

Description : This captures the order of movement of trailers in the yard on a given day, week or month

Comments : Helps in measuring the order fulfilment efficiency i.e. whether the priority orders have been serviced first or not

Metric 4

Total time in yard

Description : This captures the time spent by the trailer in the yard from the time it enters and leaves the yard

Comments : This helps in measuring the time taken to fulfill a particular request

⇒ Capturing these metrics need inputs from both WMS and TMS, and also the trailers need to have RFID tags attached to them.Then compare these performance metrics with the ones prior to the deployment of YMS to identify the percent gains in the overall operational productivity.

cheers i hope this helped !!

Energy requirements of analog and digital signals.

jek_recluse [69]

Analog signals require more energy.

Analog=Constant flowing modulated

Digital is bursts of on/off binary data.
