tss

TSS is an acronym that can refer to several concepts across different fields. The most common uses include environmental science, medicine, and computing.

Total Suspended Solids (TSS) are solid particles suspended in water that can be trapped by a filter. They are measured by passing a known volume of water through a pre-weighed filter, drying the filtrate and filter, and weighing the residue. Reported in milligrams per liter (mg/L). TSS is a key parameter in water quality assessments and wastewater treatment as it affects sediment load, turbidity, and pollutant transport.

Toxic Shock Syndrome (TSS) is a rare but potentially life-threatening condition caused by bacterial toxins, most commonly from Staphylococcus aureus or Streptococcus pyogenes. It can rapidly progress to shock and organ failure. Symptoms include fever, low blood pressure, vomiting, diarrhea, rash, and confusion. Risk factors include postoperative wounds, skin injuries, and, historically, tampon use. Early diagnosis and aggressive supportive care and antibiotics improve outcomes.

Task State Segment (TSS) is a data structure used by x86 processors with protected mode or long mode to support hardware task switching. It stores context information for a task, including stack pointers for privilege levels, register state, and I/O permission structures. In modern operating systems, hardware task switching is rarely used; the TSS remains essential for providing kernel-mode stacks during privilege transitions and for certain debugging references.

Time-Sharing System (TSS) refers to early operating systems designed to share computer time among multiple users. Notable examples include IBM's Time-Sharing System/360 (TSS/360). Time-sharing systems introduced interactive computing, remote login, and multiprogramming capabilities, which evolved into modern multitasking operating systems.
