One of the best ways to code effective programs is to write so-called structured programs, using the sequential, selection, or repetition logic structures.
Structured programs are program types that aim to improve the clarity of program codes to make them readable and reusable.
Structural codes such as the if/then/else for selection and while/for repetition are used to achieve these goals.
So, structured programs are used to write programs that follow the sequential, selection, and repetition logic structures.

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.
Using a combination of symmetric and asymmetric key encryption, Sofia sent a report to her home office in Indiana. She received an e-mail acknowledgement that her report had been received, but a few minutes later she received a second e-mail that contained a different hash total than the one associated with her report. This most likely explanation for this result is that
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.
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

It allows many developers to work on the same project from anywhere at the same time.
A full copy of all project files is stored on each developer’s computer.
It is somewhat similar to a Centralized Version Control system, with the main difference being that every team developer has a complete project copy in their own system. This allows them to work on the project without access to the internet. Instead, they make changes and update their own server version. This updated version later gets pushed to the centralized server.
Answer:
1. It allows many developers to work on the same project from anywhere at the same time.
2. Project files are maintained in a central repository.
3. A full copy of all project files is stored on each developer’s computer.

A user is configuring an email client application and decides to use the TCP/IP suite protocol that will store all messages on the email server so that they can be synchronized across a laptop, a smartphone, and a web email client. This protocol will store the email messages on the email server until the user explicitly deletes them.Which of the following TCP/IP port numbers will the client application typically use while using this protocol to contact the email server?A. 21B. 80C. 110D. 143
Answer:
D. 143
Explanation:
A server that allows the entire management of an email account through more than one email client such that the clients the messages of the clients are stored on the server pending being deleted by the user, is an IMAP server
The port that the IMAP server listens to is the port number 143, therefore, the client application typically makes use of port 143 while using the TCP/IP protocol to contact the email server
