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.
Blood clots are gel-like clumps of blood. They are beneficial when they form in response to an injury or a cut, plugging the injured blood vessel, which stops bleeding. Some blood clots form inside your veins without a good reason and don't dissolve naturally. These may require medical attention, especially if they are in your legs or are in more critical locations, such as your lungs and brain. A number of conditions can cause this type of blood clot.
