Suppose two computers (A & B) are directly connected through Ethernet cable. A is sending data to B, Sketch the waveform produced by A when “$” is sent. Also mention the OSI layer that is responsible for this.

Answers

Answer 1
Answer:

Answer:

Physical / Data link layer

Explanation:

If two computers (A & B) are directly connected through Ethernet cable. A is sending data to B, the data would be transmitted if the network is clear but if the network is not clear, the transmission would wait until the network is clear.

The Open Systems Interconnection model (OSI model) has seven layers each with its own function.

The physical layer is the first layer responsible for data transmission over a physical link. The data packets are converted to signals over a transmission media like ethernet cable.

The data link layer is the second layer in the OSI layer responsible for transmission of data packets between nodes in a network. It also provides a way of detecting errors and correcting this errors produced as a result of data transmission.

The program that you create for this exercise will begin by reading the cost of a meal ordered at a restaurant from the user. Then your program will compute the tax and tip for the meal. Use your local tax rate when computing the amount of tax owing. Compute the tip as 18 percent of the meal amount (without the tax). The output from your program should include the tax amount, the tip amount, and the grand total for the meal including both the tax and the tip. Format the output so that all of the values are displayed using two decimal places.

Two-factor authentication can best be breached by the adversary using:________. a. social engineering attack b. using sniffers like Wireshark and capturing packets c. using rootkits and privilege escalation to get to the kernel processes d. using a virus and destroying the computer that stores authentication information.

Answers

Answer:

a. social engineering attack

Explanation:

Two-factor authentication requires that the user/owner of the account enter a second verification code alongside their password in order to access the account. This code is usually sent to a personal phone number or email address. Therefore in order to breach such a security measure the best options is a social engineering attack. These are attacks that are accomplished through human interactions, using psychological manipulation in order to trick the victim into making a mistake or giving away that private information such as the verification code or access to the private email.

Does Kennesaw State University have any computing ethical policy for computer usage? If so - what is it?

Answers

Answer:

The answer to the questions: Does Kennesaw State University have any computing ethical policy for computer usage? If so - what is it? Would be as follows:

1. Yes, Kennesaw State University, a university in Georgia, does have a computing ethical policy that regulates the proper use of the facilities and computing services within the facilities of the university and the use of computing equipment that belongs to the university. This policy is known as the KSU Computer Usage Policy.

2. As said before this policy establishes that the use of computing services are not the right of a person, but rather a privilege afforded to the students, faculty and other people who are present in the university and who may need to use its computing services. The use of the computing services would be whitin this policy as long as it stays inside the delimitations established by federal, state and University policies.

3. Problem 5. A digital computer has a memory unit with 24 bits per word. The instruction set consists of 150 different operations. All instructions have an operation code part (opcode) and an address part (allowing for only one address). Each instruction is stored in one word of memory. a. How many bits are needed for the opcode? b. How many bits are left for the address part of the instruction? c. What is the maximum allowable size for memory? d. What is the largest unsigned binary number that can be accommodated in one word of memory?

Answers

The number of bits that are needed for this operation code (opcode) is 8 bits.

What is binary encoding?

Binary encoding can be defined as a standard technique that is designed and developed for converting data in plain text (source alphabets) to a form that is easily used by different operating systems (OS), especially through the use of a binary digit (bit) or two-symbol system.

How to calculate the number of bits.

The number of bits that are needed for this operation code (opcode) is given by this mathematical expression:

2^n > 150\n\n2^8 > 150\n\n256 > 150

n = 8 bits.

b. To determine the number of bits that are left for the address part of the instruction:

  • Opcode, O, I = 8 bits.
  • Instruction size = 24 bits.

Address = I-O\n\nAddress =24-8

Address = 16 bits.

c. To determine the maximum allowable size for memory:

Based on the memory unit, this is given by 2^(16)* 24

d. The largest unsigned binary number that can be accommodated in one word of memory is given by: 2^(24)-1

Answer:

a) 8 bits b) 16 bits. c) 2¹⁶ * 24 bits d) 2²⁴ -1

Explanation:

a) In order to be able to accommodate 150 different instructions, the number of bits needed must be equal to the minimum power of 2 that satisfies this equation:

2n > 150, i.e. n=8.  

b) If the total number of bits for a word is 24, and 8 are used for the op code, there are 16 bits left for the address part.

c) If the address part has 16 bits, this means that the total addressable space is just 2¹⁶, so the maximum allowable size is 2¹⁶ * 24 bits.

d) As we have 24 bits to be filled, the largest unsigned binary number is just 2²⁴ – 1.

(As we need to leave a position for all zeros).

A data structure used to bind an authenticated individual to a public key is the definition of ________. digital certificate

internet layer
data link layer

Answers

Answer:

Digital Certificate is the correct answer of this question.

Explanation:

Digital certificates are always for encryption and identification for transmitting public keys.The concept of digital certificate is a data structure used for linking an authenticated person to a public key. It is used to cryptographically attach public key rights to the organization that controls it.

For example:- Verisign, Entrust, etc.

  • An appendix to an electronic document that is used for authentication purposes.
  • A digital certificate's most frequent use is to confirm that an user sending a message is who he or she appears to be, and provide the recipient with the means to encode a response.
