Answer:
Hello there! There are 4 parts to this question, all regarding relational database concepts.
Explanation:
Parts 1, 2, 3, 4 are drawn in attachments. For Part 4, the "foreign keys" would be the id fields of the joining table, and the "primary keys" are the IDs of the table itself. Data types are "integer" for ID, "string" for text columns like Name and Location, and "Decimal" for Hourly rate in the Timesheet table. Note that we can further simplify the erd from the one constructed earlier in part 3 to remove the Project Manager model and instead add a Project Manager "boolean" flag in the Employee table since a Project Manager is also an Employee.
Answer:
n= input("Please enter the next word: ")
x=1
while(n != "STOP"):
print("#" + str(x) + ": You entered " + n)
x=x+1
n= input("Please enter the next word: ")
print("All done. " + str(x-1) + " words entered.")

Hi!
The correct answer is the a.
Explanation:
The Moore's law is an a empirical law that Gordon Moore predicted doing some observations about how the density of the transistors on a integrated circuit was increasing over time.
For example, this law state that if you have an integrated circuit with: 1000 transistors in 1980 then in 1981 and six months later you will have the same integrated circuit with 2000 transistors, and so on..
- Jan 1980: 1000 transistors.
- Jul 1981: 2000 transistors.
- Jan 1983: 4000 transistors.
- Jul 1984: 8000 transistors.
And that's the reason because its cost will fall too.
A protocol is a set of rules that governs the communications between computers on a network.
1. HTTP or HTTPs. This stands for Hypertext Transfer Protocol or Hypertext Transfer Protocol (secure).
2. FTP (File Transfer Protocol)
3. Email Protocols (POP3, IMAP, SMTP)
4. TCP(Transmission Control Protocol) and UDP(User Datagram Protocol)
Hoped that helped
Answer:
computer science is the study of computer and computing as well as theoretical and practical applications.
