World of Computer Networking Your CCNA start - Basics of Bits and Bytes

The video tutorial explains the fundamental concepts of bits and bytes. A bit, the smallest unit of information, can be represented as 0 or 1 and is transmitted differently across media like fiber optics and wireless networks. A byte consists of 8 bits and is also known as an octet. The tutorial further explores how characters are encoded using Unicode, where each character is represented by 8 bits. The video concludes by discussing the application of bits and bytes in areas such as processor architecture and networking.

Explain how different physical media transmit bits differently.

What is Unicode and how does it relate to bits and bytes?
