Why Bitcoin address are 25-34 bytes long when RIPEMD 160 & SHA-256 are only 20 bytes and 32 bytes long respectively?

Why Bitcoin address are 25-34 bytes long when RIPEMD 160 & SHA-256 are only 20 bytes and 32 bytes long respectively?

(I'm new to Bitcoin & it's technology so correct me wherever u can) .Recently I was reading about Bitcoin and it's underlying technologies. I came to know that for generating addresses Bitcoin uses RIPEMD-160(SHA-256). But most of the Bitcoin Addresses are 25 to 34 Bytes(characters) long & starts with 1 or 3. How is this possible? Is there any underlying Encryption algorithm is there along with Hashing functions like RIPEMD & SHA?

Antminer D3 Blissz Modified Firmware For Improved Performance It is not a secret that the default firmware and even settings for many of the ASIC miners that come out from the manufacturers are hardly with the best/optimal settings and often they are also limited in what you can tweak yourself. So some more advanced users take the matter in their hands in order to further optimize for performance and or stability and reliability and even add extra features that help owners of the devices to get better profit or higher profit for example. One such case is the Antminer D3 Blissz Modified Firmware for the X11 ASICs being produces by Bitmain that you might want to give a try if you have even at least one of these ASIC miners. The custom firmware promises up to 20% lower power usage and some extra features such as ASIC voltage settings per chain as well as the ability to overclock or underclock per chain as well as more control on fan operational speeds. There are some usability improveme...
