Organisations without a BYOD policy have the benefit of selecting a small number of devices to support, while organisations with a BYOD policy could also limit the number of supported devices, but this could defeat the objective of allowing users the freedom to completely choose their device of preference.
Do you know that when talking about puppies, most trainers and behaviorists consider a puppy to be a dog that is just born to about 6 months of age? This may be a bit confusing because many of us have been told over the years that a dog is a puppy until about 1 year of age.
Depending on the breed, by the time puppies are one year old, they are considered adult dogs. Some breeds of dogs take longer to mature out of their adolescent phase than others. Less than one year will be spent in cute, cuddly puppy stage, while the next ten to 15 years you will be living with the adult dog.
