Explanation:
Identify the technique to free up the CPU by allowing device controllers to independently transfer data between the device and main memory.
a. Programmed I/O.
b. Direct Memory Access (DMA).
c. Polling.
d. CPU interrupt.
Answer:
B. - Direct Memory Access (DMA)
Explanation:
...
Direct Memory Access (DMA) is the technique to free up the CPU by allowing device controllers to independently transfer data between the device and main memory. Thus, option B is correct.
What is Direct Memory Access?Direct memory access is a computer system feature that allows some hardware subsystems to access main system memory without relying on the central processor unit.
Direct memory access (DMA) is the method of transmitting data without using the CPU. It is frequently used to transport data to and from input/output devices. To manage the transfer, a second DMA controller is necessary.
DMA is a mechanism that allows an input/output (I/O) device to transmit or receive data directly to or from main memory, bypassing the CPU to speed up memory operations. A chip known as a DMA controller manages the process (DMAC).
Therefore, option B is correct.

Designers are comparing performance between a multi-core processor equipped with 16 in-order cores and a dual-core superscalar processor. The dual-core superscalar processor has two identical Out- of-Order cores. Each core is a 4-issue superscalar. The multi-core processor has 16 in-order processor cores. Each in-order core of the multi-core processor can achieve about one third the performance of the OoO superscalar core. A benchmark program K includes both sequential codes that can only be executed on one CPU core and parallel codes that can be distributed to multiple CPU cores. For program K, execution of the sequential codes takes 30% of the total execution time.

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.

Big data is processed using relational data bases. True or false
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.
