What is a cache and how do I specify one?
A cache is a temporary storage area on a computer (or other electronic device) that holds data so future requests for that data can be served faster. It is used to increase the speed of data retrieval and to optimize bandwidth usage.
To specify a cache, you will need to use a caching program or tool. This could be a library, a web server module, a plugin, or another type of software. Caching can be used in the browser or a backend application to hold data that is requested often, like web pages and images.
What are some examples of big data?
1. Social Media Data: Including posts, likes, shares, comments, and other conversations on social media platforms like Twitter and Facebook.
2. Internet of Things (IoT) Data: Sensors and other devices connected to the internet generate large amounts of structured and unstructured data.
3. GPS/location data: Tracking physical locations and movements generates incredibly large datasets.
4. Web server log data: Captures data on user activities and interactions with websites.
5. Enterprise resource planning (ERP) data: All transactions and data relevant to a company’s financial and back-end operations.
6. Healthcare and medical data: Gathering, storing, and analyzing patient data, such as medical test results, medical images, and doctor’s notes.
7. Genomic data: Large bioinformatics databases which contain the genetic makeup of various organisms.
8. Text and audio data: NLP techniques can be used to process large amounts of unstructured data.
9. Video and image data: Video data captured from surveillance cameras, drones, and satellites, as well as images captured by various sensors.
What are the four pillars of digital transformation?

What is VBE of a transistor?
VBE stands for "base-emitter voltage," which is the voltage that exists between the base and the emitter terminals of a transistor. It is usually zero or a negative voltage when the transistor is in the off state, and it can range from 0.4 to 0.7 volts for a silicon transistor when it is in the forward-biased, on state.
