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.
When a blood clot is attached to the wall of a blood vessel, it is called a thrombus. When it moves through the bloodstream and blocks the flow of blood in another part of the body, it is called an embolus. blood clot is a jelly-like mass of blood tissue formed by clotting (coagulating) factors in the blood. A blood clot is a normal reaction of the body that occurs if a blood vessel is injured. This is desirable if it occurs to stop the bleeding caused by an injury.
