Consider the following statements regarding computer programs A - Variables can contain different values at different times.B - Reserved words of a programming language can be used as variable names in that languageWhich of the following is true with respect to the above? * O Only A is correct Only B is correct Both A and B are incorrect Both A and B are correot
Answers
Answer:
The answer is: Only A is correct.
Explanation:
Variables in a program can assume different values at different times, and the program can then produce different results, depending on circumstances, so A is correct.
In a computer language, a reserved word (also known as a reserved identifier) is a word that cannot be used as an identifier, such as the name of a variable, function, or label – it is "reserved from use". This is a syntactic definition, and a reserved word may have no meaning. So, B is incorrect.
Hence, the answer is: Only A is correct.

Big data is processed using relational data bases. True or false
Answers
Answer:
false
because Big data consist of a large quantity of data that may be structured, unstructured, or semi-structured
Explanation:
The statement Big data is processed using relational data bases is false.
We are given that;
The statement about data base
Now,
Big data is not processed using relational databases, but rather using non-relational databases such as MongoDB, Cassandra, HBase, etc. Relational databases are efficient for storing and processing structured data, which has a fixed schema and can be organized into tables and columns.
However, big data often includes unstructured and semi-structured data, such as videos, photos, webpages, social media posts, etc., which do not have a predefined schema and cannot be easily fitted into tables.
Non-relational databases are more flexible and scalable for handling such diverse and large data sets.
They also allow faster and cheaper processing of big data by using a horizontal architecture that distributes the data across multiple nodes.
Therefore, by data base the answer will be false.

differentiate between standard and enhanced keyboard(10 diffrences)
Answers
Explanation:
by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.
A standard keyboard typically features a basic layout and functionality, while an enhanced keyboard includes additional features such as multimedia keys, customizable macros, and backlighting options.
The difference between standard and enhanced keyboards are as follows:
1) Key Layout: One of the primary differences between a standard keyboard and an enhanced keyboard is the key layout. A standard keyboard typically follows the traditional QWERTY layout, while an enhanced keyboard may have additional keys or modified key arrangements.
2) Extra Function Keys: Enhanced keyboards often feature additional function keys beyond the standard set found on a standard keyboard. These extra keys may provide quick access to specific functions like media controls, volume adjustment, launching applications, or controlling lighting effects.
3) Multimedia Controls: Enhanced keyboards often include dedicated multimedia controls for managing audio and video playback. These controls allow users to play, pause, stop, or skip tracks without the need to navigate through software interfaces.
4) Macro Keys: Enhanced keyboards may offer programmable macro keys that allow users to assign custom functions or complex sequences of commands to a single key press. This feature is commonly utilized by gamers or power users who require quick access to specific actions or shortcuts.
5) Backlit Keys: Many enhanced keyboards have backlit keys, allowing for improved visibility in low-light environments. These keyboards may offer adjustable backlighting levels or even customizable RGB lighting options for personalization.
6) Touchpad or Trackpad: Some enhanced keyboards include an integrated touchpad or trackpad, similar to those found on laptops. This feature eliminates the need for a separate mouse and provides cursor control directly on the keyboard.
7) Ergonomic Design: Enhanced keyboards often prioritize ergonomics by incorporating features like palm rests, adjustable tilt angles, or split keyboard layouts. These design elements aim to provide increased comfort and reduce the risk of repetitive strain injuries.
8) Connectivity Options: While standard keyboards usually come with a wired USB connection, enhanced keyboards may offer additional connectivity options such as wireless Bluetooth or specialized connectors like USB-C for faster data transfer.
9) Specialized Keys: Enhanced keyboards may have dedicated keys for specific purposes, such as gaming keyboards with keys optimized for gaming actions like WASD movement or mechanical keyboards with specialized switches for tactile feedback.
10) Software Integration: Enhanced keyboards often come with companion software that allows users to customize key functions, lighting effects, and other settings. This software integration provides additional flexibility and personalization options beyond what standard keyboards offer.

Write a complete method to create an array of random integers. The method takes in three integer parameters: the array size, the lower bound, and the upper bound. The method also takes in a boolean parameter. The method creates and returns an integer array of the specified size that contains random numbers between and lower and upper bound. If the boolean parameter is true, the upper bound is inclusive. If the boolean parameter is false, the upper bound is not inclusive (meaning it is exclusive). Note the lower bound is always inclusive. If any of the parameters are invalid, null is returned.

Answers
Answer:
i hope it will helpful for your
mark me brainlist
Explanation:
Metrics refer to a system or standards of measurement.
These are measures of quantitative assessment for the purpose of comparing, tracking and performance measurement.
When it comes to measuring employee's awareness, people's knowledge of comprehensive security awareness it can be monitored through online security awareness programs. The knowledge of the employees can be tested in regard of a hot topic i.e cybersecurity practices.
Online quizes can be used to show whether employees know the risks of leaving a computer unmonitored.
Simulated or planned cyber attacks, mockdrills can be planned by the company to test the presence of mind, readiness of employees after the training.
These things should be done without any prior notice so that the employees feel the real pressure and the situation is same as the real world
The metrics used to test the security awareness of the trained staff must be consistent, cheap to gather, can be expressed as cardinal or in percentage , and most importantly they should be contextually relevant i.e they should faciliate decision makers to take actions and attain the desired objective.
Awareness surveys are important baseline to test the knowledge of employees after the training. They are simple to set up and easy to use as well.
For example- all employees know that there is a security team but do they know their goals and policies of the team. Awareness surveys can be used to check these parameters and get the desired results from it.

By simply reducing its size the computer can be speedier as indicated above, the concept of Einstein that messages can not spread faster than light speeds gives one of the limits to how quickly computers can work.
The computers have to become smaller to make them quicker. Therefore, Toward represents the total trend in the last 70+ years physically smaller, more powerful machines perfectly.The wrong choice can be defined as follows:
For option a, it is wrong because physically larger computers acquire larger space.For option b, it is wrong because physically larger computers are acquiring in a larger space and it is more powerful.For option c, it is wrong because a small computer acquires a small space but it is less powerful as compared to physically larger.For option e, it is wrong because it is also known as a microcomputer that is powerful for both single and multiple users.Therefore "Option d" is correct.
