VRAM (video RAM) : VRAM (video RAM) is a reference to any type of random access memory (RAM) used to store image data for a computer display.    All types of VRAM are special arrangements of dynamic RAM (DRAM). VRAM is a buffer between the computer processor and the display, and is often called the frame buffer. When images are to be sent to the display, they are first read by the processor as data from some form of main (non-video) RAM and then written to VRAM. From VRAM (the frame buffer), the data is sent as a digital signal via a DVI or HDMI port to a modern, flat-screen LED display. If the display is an older cathode ray tube model -- or if the modern display is connected by an older VGA connector to the video card -- the video signal is first converted by a RAMDAC into analog signals that are sent to the display. Previous high-performance forms of VRAM were dual-ported, which means that while the processor is writing a new image to VRAM, the display is reading from VRAM ...

Process of Glomerular filtration: "What is the actual process ?" Many Zoology students have the same question. So now I am going to write about this subject.   "The first step in the urine formation is the filtration of blood plasma across Semipermiable glomerular membrane i.e. called Ultrafiltration. Approx 1 lit. of blood flow occures per min through kidney at rest.               Glomerulus is a tuft of Capillaries contained in the Bowman's capsule. Each glomerulus receives blood from an afferent arteriole and discharges its blood into an efferent arteriole. The calibre of efferent arteriole is smaller than that of the afferent develops a resistance to blood flow out of the glomeruli. As a result, a glomerular hydrostatic pressure of about 70 mmHg is created in glomerulus. This pressure is opposed by blood colloidal osmotic pressure about 30 mmHg and by Capsular hydrostatic pressure of about 20mmHg inside the Bow...
