A 2-input gate that can be used to pass a digital waveform unchanged at certain times and inverted at other times is ___________
Detalhes da Resposta
The 2-input gate that can be used to pass a digital waveform unchanged at certain times and inverted at other times is the XOR (exclusive OR) gate. An XOR gate has two input signals and one output signal. The output is HIGH (1) if the two input signals are different, and LOW (0) if the two input signals are the same. In other words, an XOR gate produces an output signal that is the "exclusive or" of its two input signals. When one of the input signals is held at a constant logic level (either HIGH or LOW), the XOR gate can be used to pass the other input signal unchanged or inverted, depending on the value of the constant signal. If the constant signal is HIGH, the output signal will be inverted; if the constant signal is LOW, the output signal will be unchanged. This property of the XOR gate makes it useful in digital electronics for a variety of applications, such as data encryption, error detection and correction, and clock synchronization.

Sensitive data can be protected from prying eyes using _________
Detalhes da Resposta
Sensitive data can be protected from prying eyes using encryption. Encryption is the process of converting data into a code or a form that cannot be easily understood without a special key or password. When data is encrypted, it is scrambled and transformed into a form that is not easily recognizable. The only way to unlock or decrypt the data is to have the specific key or password that was used to encrypt it. This means that even if someone gains unauthorized access to the encrypted data, they will not be able to read or understand it without the key or password. Encryption can be applied to many types of sensitive data, including passwords, financial information, personal data, and sensitive documents. It can be used to protect data both while it is being transmitted (e.g., through email or messaging) and while it is being stored (e.g., on a computer or server). In summary, encryption is a powerful tool for protecting sensitive data from prying eyes, by converting it into a code or a form that is not easily recognizable without the specific key or password that was used to encrypt it.

Detalhes da Resposta
The domain name of a website is also its IP address. Every device that connects to the internet, including websites, is assigned a unique Internet Protocol (IP) address, which is a numerical label. However, remembering a long string of numbers is difficult, so domain names were created to serve as more memorable and recognizable names for websites. When you type a domain name into your web browser's address bar, your browser sends a request to a Domain Name System (DNS) server, which translates the domain name into its corresponding IP address. The IP address is then used to locate the website's server on the internet and retrieve the website's content, which is then displayed in your browser. So, while the domain name is what we typically use to identify a website, it ultimately maps to its underlying IP address, which is used to connect to the website's server and retrieve its content.

Which of the memories must be refreshed many times per second?
Detalhes da Resposta
Out of the given options, Dynamic RAM (DRAM) must be refreshed many times per second. DRAM is a type of computer memory that stores data in a capacitor within each memory cell. The capacitor can hold a charge, representing either a 0 or 1, but it gradually leaks over time, meaning that the data will eventually fade away. To prevent this data loss, the memory controller sends a refresh command to the DRAM chip many times per second. This refresh command recharges the capacitors in the memory cells to maintain the data stored in them. In contrast, Static RAM (SRAM) does not require refreshing, as it uses a different type of storage element that does not leak charge like a capacitor. EPROM and ROM are non-volatile memory types, meaning that they retain data even without power, and do not require refreshing.
