1 How to Set Up, Secure and Manage A Network Home Networking 101How to Set Up, Secure and Manage A Network
2 Why NetworkNetworking is all about sharing, and it allows your computers to connect to the Internet, talk to each other, and share resources like files and printers
3 What is A Computer Network Communication system between 2 or more computers or other devices such as printers
4 Benefits of Networking Networking adds flexibility to the way you work with your computers and electronic devices. You can:Share a high-speed, broadband cable or DSL Internet connection so everyone can surf the web simultaneouslyAccess your own private account while others cruise the webShare all types of files, including music, digital pictures, and documentsStore your library of music, pictures, and files all in one placeView your digital pictures and listen to your music anywhere in the houseEnjoy multiplayer and head-to-head gaming with friends or family from any room in the houseSave money and time by sharing printers, scanners and other peripherals
5 Network vs NetworkingNetwork—Physical infrastructure, enables transmission of data—Hubs, repeaters, routers, cables, fiber optics and microwave dishesNetworking—Preparation of data for transmission and submission of data to the network, enabled by software
6 LAN vs WANLAN—Local Area Network—Devices connected in a single office or buildingWAN—2 or more interconnected LANs, geographically distantThe best example of a WAN is the Internet, which spans the entire world
7 Wired vs Wireless Wireless - communicates through radio waves Wired - communicates through data cables (most commonly Ethernet-based)
8 Advantages of Wireless Mobility and freedom - work anywhereNo restriction of wires or a fixed connectionQuick, effortless installationNo cables to buy or installEasy to expand
9 Advantages of Wired Relatively low cost Offers the highest performance possibleFast speed - standard Ethernet cable up to 100Mbps.Faster speed - Gigabit Ethernet cable up to 1000Mbps.Wired networks are best when you need to move large amounts of data at high speeds,
10 Wireless Standards Wireless-B (802.11b) Operates on the 2.4GHz frequency band and can transmit data at speeds of up to 11Mbps within a range of up to feet.Wireless-A (802.11a) –Operates at the frequency of 5 GHz, which is less crowded than 2.4GHz where telephones and microwaves may cause interference. Although the speed is up to 54Mbps, the range is only up to 75 feet. Wireless-A is incompatible with both Wireless-B and G because it operates at a different frequency.Wireless-G (802.11g) –Features the same benefits as Wireless-B, but offers 5X the speed at up to 54Mbps. Wireless-G currently offers the best combination of performance and value. You can mix Wireless-B with Wireless-G equipment, but you will lose the higher performance speeds of Wireless-G.Wireless-N (802.11n) - The next generation of high-speed wireless networking, capable of delivering the range and capacity to support today's most bandwidth-hungry applications like streaming high definition video, voice, and music. Wireless-N is based on MIMO (Multiple Input, Multiple Output) technology, which uses multiple radios to transmit multiple streams of data over multiple channels.
11 Network HardwareRouter: This is considered the heart of your network and is the device that routes all the traffic to and from the Internet to the various computers on your network.Modem: Connects your Internet service to your computer. Depending upon what type of broadband service you have, you will need either a DSL or cable modem. Or, you can purchase a gateway router which is an all-in-one solution that combines the functions of a router with a cable or DSL modem so that two separate devices are not required.
12 Network Adapters: For a desktop computer: For a laptop computer: PCI Adapter - connects inside your computerUSB Adapter--plugs into a USB port on the outside of your computerFor a laptop computer:A PC (PCMCIA) Card--slides into a slot on your laptop computerUSB Adaptor--plugs into a USB port on the outside of your computer**Most new computers come with built in devices (wired and/or wireless)
