visible light by the flow of electric current. The airplane is a flying vehicle let people were able to move faster. The Internet is a huge network tandem by network and network. These network is connected to a set of standard network TCP / IP protocol families, linking billions of devices around the world, forming a logically single large international network. The reason why the internet would be so important is because it had a wide range of information resources and services, such as…

Part B: VoIP Computer-to-Computer Voice over Internet Protocol (VoIP) is the process of taking analog signals, such as a human voice, and transmitting them over the Internet as digital data. Computer-to-computer VoIP is usually thought of as the simplest way to use VoIP, as it simply requires a computer with basic peripherals, an internet connection and can easily be used with popular software such as Skype. What devices are involved from transferring Alice’s voice to the sound that Bob receives…

Discuss the advantages of a database management approach to the file processing approach? Give examples to illustrate your answer. According to our text, database management is the process of storing data. In the early days of computers, they would use data resource management to store information in a specific location. This process was very inflexible and extremely costly. Instead, we use database management today. This process allows us to consolidate the data, and integrate it into many…

the past the networks have been essential in giving organizations a chance for computers to share devices such as printers the basic and main advantage of computer networks are sharing of information.…

professional development was purchased for classroom technology integration training. At the end of the training, teachers felt more comfortable with their knowledge of the available technology tools, but continue to have problems with less than adequate network and internet access in the classroom. Through the process of providing professional development, a nagging concern was confirmed—the infrastructure in place wasn’t capable of handling the demands necessary for true technology integration…

setup of the WAN and LAN networks that will be running through all Kudler locations. Here we will discuss the software and hardware needed for security and functionality of the network at each location. Firewalls Any connection to the internet has some risk of attack from external sources, which means our proposed setup introduces this risk at each Kudler location. To mitigate this risk, we can use a combination of software and hardware firewalls to protect the Kudler network. Hardware…

number of hosts connected to the public Internet, a confederation of networks looking much like today’s Internet, would reach a hundred thousand. The 1980s would be a time of tremendous growth. Much of that growth resulted from several distinct efforts to create computer networks linking universities together. BITNET provided e-mail and file transfers among several universities in the Northeast. CSNET (computer science network) was formed to link university researchers who did not have access to…

13349871 You want to connect different computers, at different locations, so that they can exchange data with each other. What are the different challenges that you need to overcome? Host Identification on small networks isn’t a problem as it can be set up with manual ways of addressing, but will be exponentially harder the larger a network becomes. Protocols, DHCP servers and addressing are a huge need if you want to create and sustain a large, expanding network. A standard specifies a…
