First Pentium 4 microprocessors, based on Willamette and Northwood cores, as well as some Prescott processors, were referenced by their speed. A - Northwood microprocessors with 512 KB L2 cache (for frequencies 2 GHz and lower), or Prescott CPUs with 1 MB L2 cache (for frequencies higher than 2 GHz).
What is a Superficial Blood Clot? When blood clots in the superficial veins of the leg, it is known as a superficial thrombophlebitis (or commonly, phlebitis). Patients often may experience pain and tenderness on the surface of the leg with appearance of a tender lump or streak. Many times, patients recall a varicose vein in the same area prior to the phlebitis appearing. Varicose veins are a well-recognized risk factor for superficial thrombophlebitis. While phlebitis confined to the surface veins does not pose the same serious risk as DVT, we know that some patients with phlebitis progress to DVT as that surface clot extends to the deep venous system.
What is deep vein thrombosis? Deep vein thrombosis (DVT) is a serious condition that occurs when a blood clot forms in a vein located deep inside your body. A blood clot is a clump of blood that is in a gelatinous, solid state. Deep vein blood clots typically form in your thigh or lower leg, but they can also develop in other areas of your body. Other names for this condition include thromboembolism, post-thrombotic syndrome, and post-phlebitic syndrome.
