Now create and run a sql query that displays only employee name (first name, middle initial, and last name) and job description sorted by employee last name. see the picture below for the expected result. note to accomplish this you must use concat() function and alias to get employee name grouped into one attribute named emp_name along with sorting the data prior to display. see lecture slide 71 for concat and alias and lecture slides 89 & 90 for sorting a list. additionally you will need to join emp_1 with job by job_code but only select job description to be displayed besides the employee’s name. see lecture slides 100-104 and the textbook for details.

answer:

in baseband transmission the whole bandwidth of the cable is utilized by a single signal. eg.Ethernet is using Basebands for LAN.

In the broadband transmission, multiple signals are sent on multiple frequencies simultaneously using a single channel. eg.Digital Subscriber Line (DSL)
