age group, various kinds of diseases and so on, each having respective wards. Hospital, depending upon its size requires management and funding to be operated in a beneficial way. Hospitals are usually funded by governmental organizations, non-governmental organizations (NGOs), charities and private persons in addition with other donations. Hospitals can also be 'for-profit'.

As stated earlier, there're a huge number of categories among which the hospitals can be divided. General hospitals usually look after general and all types of diseases and illness. Specialized hospitals may offer and are proficient in some special type of diseases and look after only patients having those specified diseases and problems. In addition, there are also hospitals that do not offer their services for general public, but are designed and operated under some particular and dedicated department, such as Army hospitals, in which patients are only military and army staff.

In order to ensure the safety of the health of public and people, government imposes some rules and regulations on private as well as governmental hospitals. These rules and regulations are needed to be certified with the government in order for the hospitals to deal with patients. These rules requires proper and adequate environment under which care should be taken, surgical equipment must be very cautiously monitored, Information management of the hospital should be done by proper and learned technical staff. Ability to handle 'emergency' cases should be a priority for the hospital, proper nursing should be offered, medications should have their management, transplantation services must be under safe and secure hands, and the most important of all; the rights of the individual, whether it is a doctor or a patient, must be granted and responsibilities must be met.

These standards and rules grant development and recruitment at every level of a hospital. Now-a-days, teaching of medicine and surgery is so common that many hospitals embed universities in them, and there're a lot of hospitals joined together with universities all over the world.
