Computer Networks Does anyone really know what networking is? “In the world of computers‚ networking is the practice of linking two or more computing devices together for the purpose of sharing data” (Networking Fundamentals). Now this is a great explanation but does this really help us understand? Networking has grown over many years. Where did networking come from? Lets go back to the beginning and find out how far we have come. Network research can be traced back to around the 1960’s.

of cable infrastructures has driven the rapid growth in the wireless market over the last few years.Wi-Fi is one of the wireless technology which appeared early in the wireless market. Wi-Fi is based on the IEEE 802.11 wireless local area network (WLAN) specification. Actually it was designed to be used indoors at close range for example home user and office environment. The main goal of Wi-Fi technology is to provide service for mobile computing device like laptop. But recently it is used for more

Usually a LAN is connected to a WAN (the internet) through a broadband modem which connects to an ISP. Other well known‚ more recent networks are WLAN‚ MAN‚ CAN‚ STORAGE AREA NETWORK‚ and SYSTEM AREA NETWORK. The

Title: The Latest Development in Networks and Communications 1.0 Introduction The purpose of a computer communications network is to allow moving information from one point to another inside the network. The information could be stored on a device‚ such as a personal computer in the network‚ it could be generated live outside the network‚ such as speech‚ or could be generated by a process on another piece of information‚ such as automatic sales transactions at the end of a business day

Explain why a layered security strategy helps mitigate risk and threats both external and internal. Multiple layers can be used to secure internal threats like keeping employees from accessing inappropriate material‚ update and patch workstations and run current anti-virus/malware on workstations daily. The layers also help mitigate external threats like hackers by using firewalls

Radio frequency is superior because it is fast cause it through a satellite. 3. WLAN is used in home because there easier to maintain and to take care of it I could be private. 6.2.1 The information that it’s giving me is that its showing the wireless networks around my area.
