Answer
There are four generations of computer programming languages(4GLs)But fifth generation is still on development.
Explanation
First generation programming languages(1GL) These are programming languages were used to program the very first computers which are described ts the first generation of computers .They were low level languages.
Second generation programming language (2GL) These were low level assembly languages an example is COBOL.
Third generation programming language (3GL) These are high level programming languages examples are java,c++ e.t.c
Fourth generation programming languages (4GL) These are programming languages which are more user friendly than the other three generations. They are normally used in development of commercial business software and many others
Fifth generation programming language (5GL) these are languages which are now used in problem solving .They are more user friendly and are advanced in technology.This fifth generation is still under development.

b. Simultaneously sending the same unsolicited message to many people, often in an attempt to sell them something
c. Unauthorized access, modification, or use of an electronic device of some element of a computer system
d. Altering an electronic communication to look like someone else sent the communication in order to gain the trust of the recipient
B. Lossy compression since it ensures perfect reconstruction of the photo.
C. Lossless compression since it typically results in smaller data sizes.
D. Lossy compression since it typically results in smaller data sizes.
Answer:
D. Lossy compression since is typically results in smaller data sizes.
Explanation:
You could use C, but it technically wouldn't work since Ryan wants to design an app that sends low-quality photos. A or B won't work either because perfect reconstruction of the photo is not important.
B) Each IPv6 interface is required to have a link-local address.
C) IPv6 addresses are incompatible with IPv4 networks.
D) IPv6 does not use broadcasts.
Answer:
B & D
Explanation:
B) Each IPv6 interface is required to have a link-local address.
- In IPv6, it is mandatory for every interface to have a link-local address. This address is used for communication within the local link or network segment.
D) IPv6 does not use broadcasts.
- Unlike IPv4, which uses broadcast for certain types of communication, IPv6 does not use broadcasts. Instead, IPv6 relies on multicast and anycast for similar functionality.
In IPv6, each interface is required to have a link-local address and it does not use broadcasts. Instead, it uses multicasting for sending data to specific hosts.
In the context of IPv6, the statements B) Each IPv6 interface is required to have a link-local address and D) IPv6 does not use broadcasts are both true. A link-local address is a network address that is valid only for communications within the network segment or the broadcast domain that the host is connected to. IPv6 utilizes a link-local address for local communications, often for system initialization processes before IPv6 is fully operational. Additionally, IPv6 does not use broadcasting, a communication technology which allows for data to be sent to all devices on a network. Instead, it uses multicasting, which is the act of sending data to a specified set of host computers rather than all hosts on a network.

print(“2 + 7”)
print(3 + 1)
Answer:
line 1 = 2+7 (you added quote marks)
line 2 = 4 (you did not add quote marks, which adds both nums together)
