Item Concept Description Source 1 4 basic principles that apply to all network Disconnected local networks, direct peer communication,human-readable globally unique identifiers, Direct presence and status queries. http://wiki.laptop.org/go/Network_principles 2 network switch A network switch is a computer networking device that connects devices together on a computer network, by using packet switching to receive, process and forward data to the destination device. http://www.ccontrols.com/pdf/Extv3n3.pdf 3 bandwidth Bandwidth describes the maximum data transfer rate of a network or Internetconnection. It measures how much data can be sent over a specific connection in a given amount of time. http://techterms.com/definition/bandwidth 4 a dial up connection A dial-up connection is established when two or more communication devices use a public switched telephone network (PSTN) to connect to an Internet service provider (ISP). A dial-up connection uses a standard phone line and analog modem to access the Internet at data transfer rates (DTR) of up to 56 Kbps.A dial-up connection is the least expensive way to access the Internet, but it also slowest connection.
https://www.techopedia.com/definition/25953/dial-up-connection 5 DSL Internet connection Stands for "Digital Subscriber Line." DSL is a communications medium used to transferdigital signals over standard telephone lines. Along with cable Internet, DSL is one of the most popular ways ISPs provide broadbandInternet access. http://techterms.com/definition/dsl 6 DoS attack It is an attempt to make a machine or network resource unavailable to its intended users, such as to temporarily or indefinitely interrupt or suspend services of a host connected to the Internet. https://en.wikipedia.org/wiki/Denial-of-service_attack 7 cat 5 cable A Category 5 cable (Cat5 cable) is a type of cable that is used extensively in Ethernet connections in local networks, as well as telephony and other data transmissions. Category 5 cable employs a twisted pair design, rather than a coaxial cable or a fiber-optic cable design. https://www.techopedia.com/definition/23270/category-5-cable-cat5-cable 8 Bluetooth Bluetooth is a telecommunications industry specification that describes how mobile phones, computers, and personal digital assistants (PDAs) can be easily interconnected using a short-range wireless connection. Using this technology, users of cellular phones,pagers, and personal digital assistants can buy a three-in-one phone that can double as a portable phone at home or in the office, get quickly synchronized with information in a desktop or notebook computer. http://searchmobilecomputing.techtarget.com/definition/Bluetooth 9 VPN A virtual private network (VPN) is a technology that creates an encrypted connection over a less secure network. The benefit of using a VPN is that it ensures the appropriate level of security to the connected systems when the underlying network infrastructure alone cannot provide it. http://searchenterprisewan.techtarget.com/definition/virtual-private-network 10 4 principles of computer security
1. Run frequent test to assess risk associated with computer
2.Protect your passwords and data
3. Use updated softwares and anti virus system
4. Update backup system

It may also be referred to as a T3 line.DS3 interconnect cables must be made with true 75-ohm coaxial cable and connectors. https://en.wikipedia.org/wiki/Digital_Signal_3Related Questions
