As the name indicates, and IP address is an address that computer equipment uses to be able to communicate with each other. It is made up of 4 octets (separated by a ‘.’), each of which is 8 bits in size (32 bits in total). If we look at our binary table for 8 bits, […]
Hex or Hexadecimal, is a 16-base number system with values from 0-9 as well as ABCDEF where A=10, B=11, C=12, D=13, E=14, F=15. Hex is used in many things in IT, most commonly seen in Mac addresses (A unique identity number on every Network Card). It is also seen in certain features such as HSRP […]
The first and most important thing to understand when it comes to networking is binary. Without the fundamental understanding of binary and how it works, it would be very difficult to understand IP addresses, and without an understanding of IP addresses, it’s impossible to understand networking. So what is binary? Binary is a number system […]
Bit’s, crumbs, nibbles, bytes, megabytes ??? Ever wondered why when you buy a 250 Gigabyte hard drive and you format it, you never actually get 250 Gigabytes??? Well it’s all in the exact wording used, and how the information is reported to you. If we understand the terms of binary, and the difference between a […]
