A bit is the smallest unit of value used in computers. A bit can only hold one of two values: 0 or 1. Think of it like a switch either off (0) or on (1). A group of bits makes up a byte, which is the building block of digital storage. One byte can represent a single character, like a letter, number, or symbol. For example, the letter 'A' is stored as 01000001.

Since a single byte is very small, we need larger units to measure larger files. To make calculations easier, we use larger units such as kilobytes, megabytes, and gigabytes. Each unit is 1,000 times bigger than the previous (sometimes 1024 times bigger, based on the system).

Base 10 (Decimal) systems follow the way computers function, and Base 2 (Binary) is for human communication. Computers operate using binary, which is a system of 0s and 1s. In binary, data is grouped in powers of 2: 210= 1,024. This base 2 is the natural choice for measuring things like memory (RAM), file sizes, and operating system.

Humans are more familiar with the decimal system based on the power of 10. So, for daily use, especially when discussing storage capacities like hard drives, SSDs, or internet speeds, base 10 is more straightforward.

Upload and download are two basic processes in data transfer on the internet. Upload refers to sending data from a local device such as mobile, laptop, or desktop to a remote server or another device. This process is most commonly used when sending files, emails, and social media posts.

Downloading involves receiving data from a remote server or device and sending it to your local device. The download process includes streaming videos, downloading games and documents, and saving images from Google. Both processes rely on protocols like HTTP/HTTPS for web-based transfers or FTP/SFTP for file sharing.

The upload and download speed depends on several factors, such as internet bandwidth, network congestion, and the capacity of the device. Usually, internet service providers offer different upload and download speeds. Most of the plans focus on higher download speed since most users consume more content.
