1. Define what is encompassed in the term information technology. Information technology (IT) is a computer technology (hardware and software) for processing and storing information‚ as well as communications technology (voice and data networks) for transmitting information. 0684-313637‚‚‚0717-063717 2. What are some of the ways that IT has become "pervasive"? IT has gone beyond extending communication channels within organizations. We see online stores‚ Web-based customer service offerings and

Bus Topology In a bus configuration‚ each computer in the network is responsible for carrying out its own communications without the help of a central unit. A common communications cable (the bus) connects all of the computers in the network. As data travels along the cable‚ each unit performs a query to determine if it is the intended recipient of the message. The bus network is less expensive than the star configuration and is thus widely in use for systems that connect only a few microcomputers

AODV has pooled properties of both DSR and DSDV. It uses route discovery process for sustaining route information through the basis of routing table. It is a reactive protocol as it doesn’t need to establish or maintain routes to nodes that are not involved in the communication. AODV handles route discovery process with Route Request (RREQ) messages to broadcast to neighbour nodes. The message floods through the network till the desired destination is reached. Sequence number guarantees the loop

7. A. The skull and vertebrae‚ the meninges‚ and the cerebrospinal fluid protect it. B. The functions of components of a reflex arc are the receptor‚ sensory neuron‚ center‚ motor neuron and the effector. The receptor is responsible for activating a nerve impulse in a sensory neuron that responds to a change in the body’s internal and external environment. The sensory neuron conducts the impulse needed from the receptor to travel to its axonal end in the CNS. The center is the receiving area in

However‚ our last one is unusually high. 5) The PR interval slightly elevates and then comes back down. 6) The QT interval decreases with time with a slight increase between 60 and 90s. 7) The TP interval. It slightly increases at 30s and then decreases 8) N/A 9) The R wave which decreases over time with an increase at 90-100s. Exercise 2 1. The lub sound occurs

KEY: ABE Lab 1: Prelab: Page A17‚ Questions 1 and 2: 1. What does the term genetic disease mean? What examples of generic diseases do you know about? A genetic disease is a disease caused by an absent of defective gene in the DNA. Students may know of sickle cell anemia‚ which is a disease resulting from defective red blood cells; treatment of sickle cell anemia focuses primarily on relieving pain and controlling infections and other complications that may occur. 2.

Define the following terms: 1. Horizontal Cable : A type of inside cable designed for horizontal use in non-plenum areas. While horizontal cable must be fire retardant‚ the National Electrical Code (NEC) specifications are not as demanding as those governing the use of plenum cable or riser cable. See also NEC‚ plenum‚ plenum cable‚ and riser cable. 2. Backbone Cable : Backbone cabling is the inter-building and intra-building cable connections in structured cabling between entrance facilities
