📌 Bit vs Byte: Understanding the Basics
This course covers the basics of computer data representation, starting with the difference between a bit and a byte. A bit is a binary digit with a value of either 0 or 1, representing "On" or "Off" or "True" or "False". A byte is a set of 8 bits and is used in network addresses. The network address is a unique identifier for a network and each device in the same subnet has the same network address in its IP address. Different classes of networks were created to manage the size of networks and each class has a different number of bytes reserved for network address and host part. Class A has 1 byte for network address and 3 bytes for hosts, Class B has 2 bytes for network address and 2 bytes for hosts, Class C has 3 bytes for network address and 1 byte for host. 1 Byte is equal to 8 bits.
