1. Introduction to Network Devices All networks are made up of basic hardware building blocks to interconnect network nodes‚ such as Network Interface Cards (NICs)‚ Bridges‚ Hubs‚ Switches‚ and Routers. In addition‚ some method of connecting these building blocks is required‚ usually in the form of galvanic cable (most commonly Category 5 cable). Less common are microwave links (as in IEEE 802.12) or optical cable ("optical fiber"). An ethernet card may also be required. Network interface cards

INTRODUCTION Computer networking is the engineering discipline concerned with the communication between computer systems or devices. A computer network is any set of computers or devices connected to each other with the ability to exchange data. It is sometimes considered a sub-discipline of telecommunications‚ computer science‚ information technology and computer engineering since it relies heavily upon the theoretical and practical application of these scientific and engineering disciplines

create an outline for general security solutions we must first define what is needed. I recommend that we use a multi-layered security plan. There are a total of seven domains of an IT infrastructure including user domain‚ workstation domain‚ LAN domain‚ LAN-to-WAN domain‚ WAN domain‚ remote access domain‚ and system/application domain. User domain is essentially the people who access the information system. User domains tend to receive risk due to the user’s carelessness due to lack of awareness

A Land Are Network (LAN) is a network that connects a group of computers that are within distance of each other to the same network. LAN’s are very useful when it comes to printer sharing and sending and receiving files between all the systems within the facility that share that one network. A LAN is connected by using Ethernet cables‚ adapters‚ and hubs. Its counterpart is the WAN or Wide Area Network a WAN
