on the network. 47. The distinguishing characteristic of packet switching is that once a connection is made between the source and destination, the path of the signal along the nodes is dedicated and exclusive. 48. Wireless networks use packet switching and wireless routers to forward packets from one network to another network. 49. Bandwidth is the throughput capacity, or speed, of a network, which depends on what protocol is used. 50. TCP/IP was created by the U.S. Department…

1. Ethernet Ethernet is a combination of computer networking technologies most commonly used in local, metropolitan, and wide area networks. 2. Server A computer or computer program that manages access and distributes information through a centralized service in a network. 3. IP Transit IP Transit, also known as Internet Transit, is what allows traffic from a network to cross or "transit" to a provider network. This type of service is generally used to connect one of the smaller internet…

To be able to create a computer which will be more like a human, the humans should be focusing on developing some input devices for perception, processor and memories to be able to store information like a human, software to perform, output devises to replace human hands and feet, permanently storage device and network for communication. Just creating all of this wouldn’t be enough. Inventors should be more focusing on a human sensors and perception which is very hard to program into a computer.…

Cellular networks are a type of wireless WAN. Various technologies are utilized in cellular networks but there are only three basic modes of signal communications. These are simplex, half duplex and full duplex. In simplex transmissions the signal goes in only one direction and this type is usually seen in television and radio stations. Half duplex signaling is bi-directional but each signal has to wait its turn because only one can travel at a time. Examples of half duplex are the…

Securing a network involves numerous devices and standards such as firewalls, intrusion detection methods, and various media and wireless protocols (LabSim). There are many different threats that exist. Denial of Service (DoS) attacks floods a target system with traffic in order for it to be unavailable for legitimate requests from users. A Distributed DoS (DDoS) attack uses slave…

Philadelphia are 215, 50 and 307 miles away respectfully with Washington being 439 miles away. To cover such a vast space a combination of LAN, MAN and WAN networks are required to connect these areas. Within the five areas; Boston, New York, Providence, Washington DC and Philadelphia the local surrounding buildings are likely to be connected via a LAN, these LAN 's are then connected via a MAN to an internet backbone (BN). The MAN 's are then connected to each other and the BN via a WAN. The…

Task 1 Phones The first phone data communication was invented by Alexander Graham Bell in 1874-1876. But the very first person to be able to convey sounds over a taut extended wire by mechanical vibrations was Robert Hooke in 1667 so it’s the culmination of work done by many individuals until Alexander Graham Bell created a telephone. The earlier development is when sound waves are carried as mechanical vibrations along the string or wire from one diaphragm to the other. A very good example…
