A . The transport layer divides a data stream into segments and may add reliability and flow control information. B . The data link layer adds physical source and destination addresses and an FCS to the segment. C . Packets are created when the network layer encapsulates a frame with source and destination host addresses and protocol-related control information. D . Packets are created when the network layer adds Layer 3 addresses and control information to a segment. E . The presentation layer translates bits into voltages for transmission across the physical link.

You want to retrieve all employees, whether or not they have matching departments in the departments table. Which query would you use？（）<img src='https://img2.soutiyun.com/shangxueba/ask/18264001-18267000/18266966/2018080111484519157.jpg' /> A. SELECT last_name, department_name FROM employees NATURAL JOIN departments; B. SELECT last_name, department_name FROM employees JOIN departments ; C. SELECT last_name, department_name FROM employees e JOIN departments d ON (e.department_id = d.department_id); D. SELECT last_name, department_name FROM employees e RIGHT OUTER JOIN departments d ON (e.department_id = d.department_id); E.
