The Development of the Periodic Table Although Dmitri Mendeleev is often considered the ‘father’ of the periodic table‚ the work of many scientists contributed to its present form. Between 1817-1829‚ Johann Dobereiner began to group elements with similar properties in to groups of three or triads. This began when he noticed that the atomic weights of strontium (Sr) were halfway between Calcium (Ca) and Barium (Ba). He stated that nature contained triads of elements in which the middle element

NETWORK Computer Network also called Network is a group of computers and other devices connected to each other to share resources electronically. Networks can be as small as two computers or many thousand computers that are connected to one another. These computers are usually connected to one another through wires‚ satellite‚ and modems. Each device connected to the network is called a “node”‚ and the computer that is connected to the network is called a workstation. There are several ways

Hello all‚ when it comes to designing a wireless network there are four steps to follow the first is the correct deployment scenario like Ad hoc or peer-to-peer‚ infrastructure‚ point-to-point and point-to-multipoint remote wireless bridge‚ Ethernet to wireless bridge‚ and wireless gate. However‚ infrastructure is the most commonly used with an access point connected to a wired infrastructure. The second step is to select the IEEE wireless network type 802.11a/b/g/n depending on what type of applications

in the protection of assets. No computer system or network achieves perfect security; even a system switched off with its hard drive removed sunken in a lead case in the bottom of a deep pool in an underground facility lacks security‚ as it guarantees integrity and confidentiality but completely sacrifices availability. As a security professional‚ you must understand the risks a network faces; you must‚ in essence‚ know how to bring the network down‚ to steal the data you want‚ and to falsify important

Bus Topology Bus networks (not to be confused with the system bus of a computer) use a common backbone to connect all devices. A single cable‚ the backbone functions as a shared communication medium that devices attach or tap into with an interface connector. A device wanting to communicate with another device on the network sends a broadcast message onto the wire that all other devices see‚ but only the intended recipient actually accepts and processes the message. Ethernet bus topologies are
