If a network has a subnet mask of 255.255.255.128, how many subnets can be created?

If a network has a subnet mask of 255.255.255.128, how many subnets can be created?

Step 1: Understand what a subnet mask is. A subnet mask helps divide a network into smaller parts called subnets.
Step 2: Look at the subnet mask given: 255.255.255.128. This is in decimal format.
Step 3: Convert the subnet mask to binary. 255.255.255.128 in binary is 11111111.11111111.11111111.10000000.
Step 4: Count the number of bits used for the network part. The first 25 bits (the 1s) are for the network.
Step 5: The remaining bits (the 0s) are for hosts. In this case, there are 7 bits left (32 total bits - 25 network bits = 7 host bits).
Step 6: To find out how many subnets can be created, we look at the bits used for subnetting. Here, 1 bit is used for subnetting (the first 0 in the last octet).
Step 7: Use the formula 2^n, where n is the number of bits used for subnetting. Since we have 1 bit, we calculate 2^1.
Step 8: Calculate 2^1, which equals 2. This means we can create 2 subnets.
