t. e. The Spanning Tree Protocol (STP) is a network protocol that builds a loop-free logical topology for Ethernet networks. The basic function of STP is to prevent bridge loops and the broadcast radiation that results from them. Spanning tree also allows a network design to include backup links providing fault tolerance if an active link fails ...
The Multiple Spanning Tree Protocol (MSTP) and algorithm, provides both simple and full connectivity assigned to any given virtual LAN (VLAN) throughout a bridged local area network. MSTP uses bridge protocol data unit (BPDUs) to exchange information between spanning-tree compatible devices, to prevent loops in each Multiple Spanning Tree ...
Until 1982, STP was defined as a temperature of 273.15 K (0 °C, 32 °F) and an absolute pressure of exactly 1 atm (101.325 kPa). Since 1982, STP has been defined as a temperature of 273.15 K (0 °C, 32 °F) and an absolute pressure of exactly 10 5 Pa (100 kPa, 1 bar). NIST uses a temperature of 20 °C (293.15 K, 68 °F) and an absolute ...
Leprosy, also known as Hansen's disease (HD), is a long-term infection by the bacteria Mycobacterium leprae or Mycobacterium lepromatosis. [4][7] Infection can lead to damage of the nerves, respiratory tract, skin, and eyes. [4] This nerve damage may result in a lack of ability to feel pain, which can lead to the loss of parts of a person's ...
STP was first synthesized and tested in 1963 by Alexander Shulgin, who was investigating the effect of 4-position substitutions on psychedelic amphetamines. [3]In mid-1967, tablets containing 20 mg (later 10 mg) of STP were widely distributed in the Haight-Ashbury District of San Francisco under the name of STP, having been manufactured by underground chemists Owsley Stanley and Tim Scully.
Typhoid fever, also known simply as typhoid, is a disease caused by Salmonella enterica serotype Typhi bacteria, also called Salmonella typhi. [2][3] Symptoms vary from mild to severe, and usually begin six to 30 days after exposure. [4][5] Often there is a gradual onset of a high fever over several days. [4]
59,000 per year worldwide [6] Rabies is a viral disease that causes encephalitis in humans and other mammals. [1] It was historically referred to as hydrophobia ("fear of water") due to the symptom of panic when presented with liquids to drink. Early symptoms can include fever and abnormal sensations at the site of exposure. [1]
Schistosomiasis, also known as snail fever, bilharzia, and Katayama fever, [1][2][9] is a disease caused by parasitic flatworms called schistosomes. [5] The urinary tract or the intestines may be infected. [5] Symptoms include abdominal pain, diarrhoea, bloody stool, or blood in the urine. [5] Those who have been infected for a long time may ...
