Expert Solution & Answer
Chapter 12, Problem 1RQ
Program Description Answer
The protocol used for transferring the files over internet is FTP.
Hence, the correct answer is option “C”.
Expert Solution & Answer
Explanation of Solution
FTP:
- FTP can be abbreviated as File Transfer Protocol.
- The file transfer web application uses the FTP as application layer protocol.
- The FTP is a standard application layer tool in a
computer network which is used to transfer files between client and server.
Explanation for incorrect options:
Port:
- Port is a device that acts as a socket and connects the external devices with the system unit. It is an interface used in the connection of devices.
Hence, the option “A” is wrong.
HTTP:
- The web application uses Hyper Text Transfer Protocol (HTTP) as application layer protocol. It is an application protocol for distributive, collaborative, and hypermedia
information systems.
Hence, the option “B” is wrong.
SMTP:
- Simple Mail Transfer Protocol (SMTP) is used in E-mail related applications. It is only an application layer delivery protocol which is an internet standard for electronic mail transformation.
Hence, the option “D” is wrong.

1 An Extended Full Adder
In this Section, we are going to design an extended full adder circuit (EFA). That EFA takes 6 one bit inputs: aj, bj,
Cin, Tin, t₁ and to. Depending on the four possible combinations of values on t₁ and to, the EFA produces 3 one bit
outputs: sj, Cout and rout.
The EFA can be specified in principle by a truth table with 26 = 64 entries and 3 outputs. However, as the EFA
ignores certain inputs in certain cases, it is easier to work with the following overview specification, depending only
on t₁ and to in the first place:

Write a C program that is passed a virtual address (in decimal) on the command line and have it output the page number and offset for the given address. As an example, your program would run as follows: ./addresses 19986 Your program would output: The address 19986 contains: page number = 4 offset = 3602 Writing this program will require using the appropriate data type to store 32 bits. We encourage you to use unsigned data types as well. Programming Projects Contiguous Memory Allocation In Section 9.2, we presented different algorithms for contiguous memory allo- cation.
