Answer:
The answer to this question is given below in the explanation section
Explanation:
The correct answer to this question is: it used a more English-like syntax.
The software developer use high-level language to develop or author the program because it is more likely to English syntax and it would be easy for a software developer to author a program easily instead of using low level language and remembering ones and zeros.
Other options are not correct because:
It can be used on computers without microprocessors: Each computer has a microprocessor either you develop a program using high-level or low-level languages. Changes and modifications are easy in high-level language than in low-level languages. so, the option that prevents anyone from making changes to the software later is wrong. However, high-level languages are less complicated in learning and in authoring the programs but it does not use zeros and ones, it uses English-like syntax. So, the last option is also wrong.
Answer:
Layer 4
Explanation:
MAC address works at the data link layer (layer 2) of the OSI model. Mac address allows computers to uniquely identify themselves in the network
IP Address is a logical address that works at the network layer of OSI model (layer 3) (actually the IP layer of TCP/IP model).
The port number works at the transport layer of the OSI model (layer 4).The port number uses sequence number to send segments to the correct application thereby ensuring they arrive in the correct order.
