When PCs all had parallel bus architecture, the UART's purpose was to convert bytes from the PC's parallel bus to a serial bit-stream. The cable going out of the serial port is serial and has only one wire for each direction of flow. The serial port sends out a stream of bits, one bit at a time.
Three primary characteristics of connective tissue have been described as: Have a rich supply of blood vessels. Composed of many types of cells. Great deal of noncellular, â¦ nonliving material (matrix) between the cells of connective tissue.oose Connective Tissue consists of a lot of ground substance and it has all 3 types of protein fibers. Dense Connective Tissue on the other hand has little ground substance, â¦ few cells, and although it has most protein fibers it mainly consists of collagen fibers.
All of the various tissues of the human body can be categorized into four basic tissue types. All organs are built of these four tissues, which have consistent characteristics and arrangements from organ to organ.Thus an appreciation of the major features of these four basic tissue types can greatly simplify your understanding of the cellular composition of the many organ systems.1  OVERVIEW.More] [Examples]. Connective Tissue supports other tissues. Connective tissue consists of several cell types and extracellular products which, together, provide essential functions of mechanical reinforcement, immune surveillance, transport/diffusion of nutrients and wastes, and energy storage (fat).
