A port expander essentially allows one to become two. What I mean by that is it allows more than one device to connect to a single port. Expanders are equivalent to splitters or extension cords in everyday life. They are usually inside the computer on the motherboard, with the only visible part of it being the extension plate showing multiple ports. Some example of the type of ports that we’ve covered and that I’m familiar with are: Ethernet Port Firewire Port Serial Port VGA Port Audio/Video

A port expander is a device that allows one port on a computer system to connect to multiple devices. There are two forms of port expanders: internal and external. An internal expander has a connection inside the computer, typically on the motherboard and the only part the user sees is the expansion plate that contains multiple ports. As for an external device, it plugs into the existing port and then has multiple places to connect. The most common versions are used for USB and Ethernet ports. There

Osteoporosis is also known as wear and tear arthritis. According to “The Department of Health” (2010), “There are a number of ways of specifically reducing the risk of the onset of arthritis and osteoporosis, including avoiding joint injury, avoiding vitamin D and calcium deficiencies, and falls and falls injuries prevention strategies.” (Risk factors specific to arthritis and osteoporosis). Some prevention strategies are proper nutrition, exercising, good posture, and routine doctor check-ups. Proper nutrition

expansion plate containing multiple ports. An external device plugs into the existing port and then has multiple places to connect. Now days there are no specific types of ports for different computers. Pretty much all computers from PC to Mac have all the same ports on them. One example of a port that was more specific just to Macs is the firewire, though these days firewire is rarely used. There are advantages and disadvantages of using a port expander. An advantage is that you get more ports to

1. Parallel Ports A parallel port is a type of interface found on computers (personal and otherwise) for connecting peripherals which is a device that is used to put information into or get information out of the computer. It was designed by manufacturers Centronics, Dataproducts, Intel, IBM, Compaq, and Nortel from 1971-1981. In computing, a parallel port is a parallel communication physical interface which can be also known as a printer port or Centronics port. The port today is seeing decreasing

Vitamin D is a group of fat-soluble secosteriods responsible for enhancing intestinal absorption of calcium, iron, magnesium, phosphate and zinc. Vitamin D plays a vital role in bone metabolism and seems to have some anti-inflammatory and Immune-modulating properties. In addition, recent epidemiologic studies have observed relationships between low vitamin D levels and multiple diseases, as well as the need for vitamin D supplementation in breastfed infants and the elderly. Vitamin D is a hormone

risk for osteoporosis if there is familial history of the disease. However, research has shown that the risk of the disease and the effects of the disease can be reduced if people participate in weight bearing aerobic exercise, take calcium and vitamin D supplements and, for postmenopausal women, take hormone supplements. According to the readings I found, once osteoporosis is established, it is difficult to treat. So, preventative efforts are of greatest importance. Parents need to assure that their

Bone is composed of two different components. Collagen which is a protein that creates the woven like framework. Collagen also helps bones become flexible. Bones are also made of Calcium, which strengths them. Osteoclasts are responsible for breaking down old bone, while osteoblasts are responsible for replacing them with new bones. Bone remodeling consists of removing the old bone and replacing it with new bone. There are three phases that occur during this process. Resorption, which is basically
