Question 6 options: This is a category or partitioned group of the small units of a programming language include its numeric lit
Wittaler [7]

Lexeme is a category or partitioned group of the small units of a programming language include its numeric literals, operators, and special words.

<h3>What is a lexeme in programming?</h3>

Lexemes are known to be those character strings that are put together from the character group of a program, and the token stands for what aspect of the program's grammar they are made of.

Hence, Lexeme is a category or partitioned group of the small units of a programming language include its numeric literals, operators, and special words.

Using web-safe fonts and colors is something you can do to increase blank
Lostsunrise [7]

Using web-safe fonts and colors is something you can do to increase user experience and reliability when creating a web app by ensuring compatibility.

<h3>What are web-safe fonts and colors?</h3>
  • Fonts and colors are considered web-safe when they are included in the basic installation of web browsers.
  • What this means is that these fonts and colors come preinstalled in browsers.
  • This ensured compatibility leads to increased reliability.
  • Having a reliable web app improves user experience and makes for a more successful application.

Therefore, given that web-safe fonts and colors are just those that come preinstalled in most web browsers, using these during the development of your web app will ensure that most users will not have any issues. This increases reliability and improves the user experience.

True or False: Cracking a Vigenère cipher with brute force takes longer than a Caesar cipher, but it is still a reliable method
iragen [17]

Answer:

False

Explanation:

The Vigenere cipher is an encryption method that uses a series of interwoven Ceaser ciphers and a keyword to encrypt text. The difference between this cipher and the Ceaser cipher is the tabular interwoven Ceaser cipher and the keyword.

Multiple keywords can be used in the Vigenere cipher. The use of this keyword makes the brute-force decipher algorithm unreliable for decoding text encrypted with it.

Advantages and disadvantages of isolated I/O
Vika [28.1K]

Answer:

Input and output devices (I/O) are the parts of a computer system, such as the keyboard or the modem, that send or receive information to and from the computer's processors. In memory-mapped I/O systems, I/O devices use part of the computer's memory as the address for transmitting messages. In computers with isolated-memory systems, I/O and memory have different addresses.

I/O

Computer systems can map I/O to an address in the memory banks because the process of messaging I/O devices is similar to exchanging data with computer memory. The same bus -- the electronic pathway for transmitting information to and from the processors -- serves to access both memory and input and output devices. One disadvantage to isolated memory is that memory-map systems are simpler for the bus, as it uses the same set of addresses for I/O and memory operations.

Explanation:

hope that this helps
