What is it?
Pneumonia is defined as an inflamation. It is usually caused by infection and involves the alveoli, of the lungs. It occurs in patients, of all age groups. However, young children and the elderly, as well as immunocompromised and immune deficient patients, are especially at-risk.
Signs and symptoms
These include:
Common
Cough with greenish or yellow mucus
Fever with shaking chills (rigors)
Sharp or stabbing chest pain, worsened by deep breaths or coughs
If untreated, pneumonia progresses to sepsis ("blood poisoning") and acute respiratory distress. Primarily, these are the causes of death, in patients with untreated pneumonia.

Classifications (including "walking")
There are several classification. They are microbiological, radiological, age-related, anatomical, and point-of-acquiring infection. Generally, these types are used:
lobar - pneumonia resulting in the consolidation of a pulmonary lobe (generally due to Streptococcus pneumoniae)
multilobar - pneumonia resulting in the consolidation of more than one lobe
community-acquired - pneumonia in a patient who is, or has, not recently been in the hospital
hospital-acquired or nosocomial - pneumonia in a patient in a hospital (or recently discharged)
walking pneumonia - outdated term, pneumonia in a patient who is still able to walk, a mild pneumonia, usually due to mycoplasma
pneumococcal - pneumonia due to S. pneumoniae.
atypical - pneumonia due to either Mycoplasma, Chlamydia, or Legionella.
