Which of the following accurately describes the overall trend in computing during the past 70-plus yearsa.
a. Toward physically larger, more powerful computers.
b. Toward physically larger, less powerful computers.
c. Toward physically smaller, less powerful computers.
d. Toward physically smaller, more powerful computers.
e. Toward physically smaller, single-use computers.
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.

differentiate between standard and enhanced keyboard(10 diffrences)
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.

If a printer can print 10 characters per second how many minutes (rounded) would it take to print a page with 66 lines of 80 characters each
Answer:
8.8 Minutes
Explanation:
10 characters per second and 80 characters per line. 80/10=8 describes how many seconds it would take per line. Then multiply the time it takes per line by the number of lines which would be 8x66. Then from there you get 528 seconds and by doing some divison you get 8.8 minutes.

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
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.
