Compact discs (CDs) are capable of storing up to 700 megabytes (MB) of data. This storage capacity was revolutionary when CDs were first introduced in the 1980s, as it allowed for much greater storage than previous formats like cassette tapes or floppy disks.
CDs were initially designed for storing and playing music, but their versatility quickly made them popular for storing all kinds of data, including software, documents, and multimedia content like photos and videos.
While CDs have largely been supplanted by digital storage methods like USB drives and cloud storage, they are still used for certain purposes like distributing music albums or software installations. Additionally, some people still enjoy the tangible feel and aesthetic of physical CDs and continue to collect and play them. CDs also have a reputation for being more durable than digital storage methods, as they are less susceptible to data loss from magnetic fields, viruses, and other forms of damage.
In conclusion, CDs are capable of storing up to 700 MB of data and have been a popular and versatile storage format for several decades. While they have largely been replaced by digital storage methods, they still have certain advantages and continue to be used for specific purposes.

what was the result of the attempt to make des more secure so that it could be used for longer?
The attempt to make DES more secure resulted in the development of Triple DES.
In the 1990s, it was becoming clear that the 56-bit key length of DES was no longer sufficient to protect sensitive data from advanced attacks. In response, the National Institute of Standards and Technology (NIST) launched an effort to develop a successor to DES. This effort resulted in the selection of the Rijndael cipher as the Advanced Encryption Standard (AES) in 2001.
However, in the interim period, there was a need for a more secure version of DES that could be used until AES was widely adopted. This led to the development of Triple DES (3DES), which involves applying the DES algorithm three times with two or three different keys. This effectively increases the key length to 112 or 168 bits, making it much more resistant to brute-force attacks.
While 3DES has been widely used for many years, it is now considered less secure than modern ciphers like AES. In fact, NIST has recommended that organizations phase out the use of 3DES in favor of stronger algorithms.

perhaps the most common form of protection from unauthorized use of a computer system is the ____.
Perhaps the most common form of protection from unauthorized use of a computer system is the use of passwords. Passwords provide a secure and straightforward method of authentication, ensuring that only authorized users can access the computer system or specific resources within it.
By requiring a user to provide a unique and private combination of characters, the system can verify their identity and grant them access based on their privileges.
Strong passwords typically include a mix of uppercase and lowercase letters, numbers, and special characters, making it difficult for unauthorized individuals to guess or crack the password using brute force attacks. It is also essential to change passwords regularly and avoid using the same password across multiple accounts or systems.
In addition to passwords, other methods of protection can be employed, such as two-factor authentication (2FA), which requires a user to provide an additional layer of verification, such as a code sent to their mobile device or a fingerprint scan. This adds an extra level of security, ensuring that even if a password is compromised, unauthorized access is still prevented.

network interface cards (nic) are connected through ________ on the system board.
Answer:
Explanation:
sidelines
The answer to the question is that network interface cards (NIC) are connected through expansion slots on the system board.
There are several types of expansion slots on a system board, including Peripheral Component Interconnect (PCI), PCI Express (PCIe), and Industry Standard Architecture (ISA) slots. The type of slot used for connecting a NIC will depend on the age and specifications of the system board. PCI and PCIe slots are the most commonly used for modern NICs, as they provide high-speed data transfer rates and are compatible with most network standards. ISA slots, on the other hand, are an older technology that is rarely used for NIC connections today.
These expansion slots are typically PCI or PCIe slots, which allow the NIC to communicate with the computer's processor and other components for efficient data transfer.

in data encryption, the https in a browser address bar indicates a safe http connection over _____.
In data encryption, the https in a browser address bar indicates a safe http connection over SSL/TLS (Secure Sockets Layer/Transport Layer Security) protocol.HTTP (Hypertext Transfer Protocol) is a protocol used for transmitting data over the internet, such as web pages and other resources.
However, HTTP is not secure by itself, as the data being transmitted can be intercepted and read by third parties. To address this issue, SSL (Secure Sockets Layer) and its successor, TLS (Transport Layer Security), were developed to provide secure communication over the internet.When a website uses SSL/TLS, it encrypts the data being transmitted between the web server and the client (such as a web browser), making it more difficult for an attacker to intercept and read the data. The "https" in a browser address bar indicates that the website is using SSL/TLS to encrypt the data being transmitted. Additionally, some web browsers also display a padlock icon in the address bar to indicate that the connection is secure.
