Question 1

In terms of an authentication protocol,the phrase 'something a person possesses' could refer to ____.
A) a password
B) an ID card
C) biometrics
D) none of the above

Accepted Answer

"Something a person possesses" refers to an object that a person physically holds, such as an ID card or a key fob. This is known as a possession factor and is one of the three common factors used in authentication (the other two being knowledge and inherence factors). A password would fall under the knowledge factor, while biometrics would fall under the inherence factor. Therefore, the best choice for "something a person possesses" is an ID card (option B).

Question 2

-The ____ in machine language is a command word for an operation such as add,compare,or jump.
A) op code
B) operand
C) ALU
D) instruction code

Accepted Answer

The op code, or operation code, is a command word in machine language that instructs the computer to perform a specific operation such as add, compare, or jump. It is typically represented by a numerical code or a sequence of bits that is understood by the computer's processor. The other choices, including operand and ALU, are important components of a computer's architecture but are not synonymous with op code.

Question 3

____ intercepts information sent over computer networks.
A) Brute force
B) Sniffing
C) Phishing
D) Cracking

Accepted Answer

Sniffing, also known as packet sniffing, is a technique used to intercept information sent over computer networks. This can be done using software or hardware tools that are able to capture and analyze network traffic, allowing the attacker to view sensitive information such as passwords, usernames, or credit card details. Brute force, cracking, and phishing are different types of attacks that do not necessarily involve intercepting network traffic.

Question 4

A collection of preprogrammed activities such as addition,subtraction,counting,and comparison is called a(n)____.
A) compiler code
B) interpreter code
C) machine code
D) instruction set

Accepted Answer

A collection of preprogrammed activities is called an instruction set, which provides the basic operations that a computer can perform. Compiler code, interpreter code, and machine code are all related to programming languages and how they are translated and executed by a computer, but they do not refer to a collection of preprogrammed activities.

Question 5

In terms of an authentication protocol,the phrase 'something a person is' refers to a(n)____.
A) password
B) ID card
C) biometric device
D) none of the above

Accepted Answer

"Something a person is" refers to a biometric device, which verifies identity based on unique physical characteristics such as fingerprints, facial recognition, or iris scans. Passwords and ID cards are examples of "something a person knows" and "something a person has" authentication factors, respectively.

Question 6

-____,as shown in the accompanying figure,can be directly executed by the processors's circuitry.
A) Machine sets
B) Machine language
C) Programming language
D) none of the above

Question 7

A ____ is a series of characters that becomes a person's unique identifier.
A) PIN code
B) password
C) user ID
D) all of the above

Accepted Answer

A user ID is a series of characters that identifies a person on a system or platform. A PIN code and password are both types of authentication used to verify a person's identity, but they are not necessarily unique identifiers on their own.

Question 8

-The ____ is the part of the microprocessor that performs arithmetic operations,as shown in the accompanying figure.
A) control unit
B) RAM
C) ALU
D) ADD

Accepted Answer

The answer of 
-The ____ is the part of the...

Question 9

A(n)____ converts and executes one statement at a time.
A) compiler
B) interpreter
C) converter
D) instruction

Accepted Answer

An interpreter converts and executes one statement at a time, while a compiler converts the entire program into machine code before execution. Choice C (converter) and Choice D (instruction) do not accurately describe the process of converting and executing code.

Question 10

In terms of an authentication protocol,the phrase 'something a person knows' refers to ____.
A) a password
B) an ID card
C) biometrics
D) none of the above

Accepted Answer

"Something a person knows" commonly refers to a password as a way to authenticate and verify a user's identity.

Question 13

A ____ attack uses password-cracking software.
A) brute force
B) sniffing
C) phishing
D) cracker

Accepted Answer

Brute force attack is a type of cyber attack where hackers use automated password-cracking software to guess millions of passwords until they find the correct one. It is a time-consuming process, but it can crack even the toughest passwords.

Question 14

-The accompanying figure represents the instruction cycle.The third step is Box C and represents the ____.
A) fetch instruction
B) interpret instruction
C) execute instruction
D) increment pointer

-The accompanying figure represents the instruction cycle.The...

Question 15

A(n)____ converts all the statements in a program in a single batch; the resulting collection of instructions is placed in a new file.
A) compiler
B) interpreter
C) converter
D) instruction

Accepted Answer

A compiler converts all the statements in a program in a single batch and produces a new file of machine-language instructions that the computer can execute directly. This is a different process than interpretation, which executes each statement one at a time as it is encountered, rather than converting the entire program at once. "Converter" and "instruction" are not appropriate choices as they do not accurately describe the process of compiling a program.

Question 16

-The ____ from an instruction specifies the data.
A) op code
B) operand
C) ALU
D) instruction code

Accepted Answer

The operand is the part of the instruction that specifies the data. The op code specifies the operation to be performed, the ALU is the Arithmetic Logic Unit which performs the operation specified by the instruction, and the instruction code is the entire instruction, including the op code and operand.
