the second generation computer used. as a memory device
Answer:
The period from 1959-1965 was the second generation. Transistors that are cheaper, consumed less power, were used in this generation, were more compact, were more reliable, and were faster than first-generation vacuum tubing machines.
Explanation:
The primary memories and the magnet tapes and magnetic discs were used as secondary storage equipment in this generation.
The montage language and high programming languages such as FORTRAN, COBOL, have been used in this generation. The computers used batch processing and operating system multi-programming.
A memory is like the brain of human beings. It is used for storing information and instructions. Computer memory is the storage space on the computer that processes data and saves instructions for processing.
The memory is split into many small parts known as cells. There is a unique address for each location or cell, which varies from 0 to memory minus one.
There are three basic types of memory:
Memory Cache
Main Memory/Primary Memory
The Memory of a Second Kind

Data stored on physical storage devices must do what before the processor can access it? Be converted to binary Be written to the hard drive Go into short-term memory Go from volatile to nonvolatile memory
Answer:
Go into short-term memory
Explanation:
Data stored on physical storage devices must go into short-term memory before the processor can access it.
This is because, physical storage devices are secondary memory which store information for a long time. The CPU does not work directly with secondary memory but with primary or short term memory. Since the CPU works mainly with short term memory, information in physical storage or secondary memory has to go into short term memory for the CPU to be able to process it.
So, data stored on physical storage devices must go into short-term memory before the processor can access it.

In 2004, a large department store chain in Germany was forced to withdraw customer loyalty cards when the press discovered that the company had secreted radio-frequency identification (RFID) tags in the plastic. Even when enclosed in a wallet or purse, these cards can transmit information over distances of about a meter, and the stores planned to use them to track which departments the customer visited. At issue was which data security issue
Answer:
the data security issue at issue was consumer privacy.
Explanation:
Consumer privacy refers to how sensitive personal information provided by customers is handled and protected throughout routine transactions.
Consumer privacy is ingrained in all of contact with consumers. Consumer privacy is crucial since it can have an impact on a company's brand, disrupt the customer experience, and potentially harm its reputation.
A company's failure to preserve consumer privacy can prohibit it from generating more income and gaining new customers.

Group of answer choices.
A) the public key had been compromised.
B) the private key had been compromised.
C) the symmetric encryption key had been compromised.
D) the asymmetric encryption key had been compromised.
Answer:
C) the symmetric encryption key had been compromised.
Explanation:
Cyber security can be defined as preventive practice of protecting computers, software programs, electronic devices, networks, servers and data from potential theft, attack, damage, or unauthorized access by using a body of technology, frameworks, processes and network engineers.
In Cyber security, encryption is a form of cryptography and typically involves the process of converting or encoding informations in plaintext into a code, known as a ciphertext.
Typically, an information or data that has been encrypted can only be accessed and deciphered by an authorized user.
Some examples of encryption algorithms are 3DES, AES, RC4, RC5, and RSA.
Email encryption is the encryption and authentication of an email to protect the message therein from being read by any person other than the intended recipients. Thus, it protects the email from hacking or invasion by a third party.
Basically, when the message is signed with the sender's private key, the receiver can verify its authenticity using the sender's public key.
Also, encrypting the email message with the receiver's public key provides confidentiality.
In this scenario, the most likely explanation for this result is that the symmetric encryption key had been compromised.
