  1. History Setup, security, etc Backup Utilities Computers

  2. Computer History • 300BC-Abacus • 1946-ENIAC • 1971-Intel 4004 chip • 1977-Apple 2+ • 1980-IBM and Tandy PC • 1991-Internet, WWW • Compaq “portable” • Laptop • Smartphone

  3. 101 • New computer • Isolated vs. Networked • Intranet vs. internet • Network Interface Card (NIC) • Networking Basics • Firewall/Router • Browser • Anti-virus/spam

  4. Isolated Computer • No email • No browsing • No sharing • Can do Excel, Word, maintain database etc • Very safe! • Yet can still infect with floppy or disk • (sneaker-net)

  5. Computer Parts • Motherboard with sound card • Storage-HD and floppy? • Modem/LAN • DVD/CD writer • SD card • Ports • USB’s • Firewire-1394 IEEE

  6. Trash a Computer • Remove data • Software-Eraser • Open HD and destroy platters • Destroy CD in shredder

  7. Firewall / Router • Use OpenDNS rather than ISP’s DNS • IP address-fixed vs. DHCP • Turn off Plug and Play (UPnP) • NAT translation • Stateful packet inspection

  8. Wireless Access Points Standards-802.11 - a,b,g,n Speeds – 11-54mb/s or more Encryption-most important • WEP-bad • WPA-good MAC address-fair SSID-fair

  9. Network History • Connections-centralized vs. distributed • Bus/typology-Star, MESH • Wiring • Coaxial 10Base2, 10Base10 • Ethernet - 100MB-1GB, RJ45 adapter • Network interface card (NIC) • Local Area Network (LAN) • Wide Area Network (WAN)

  10. Connections WanPC WAN MODEM ROUTER AP VONAGE LAN PC

  11. Networks1 • In past: • Centralized-using mainframe and CRT terminals • Present: • Client-server • Future: • Centralized using thin clients • Google, Microsoft • Web service-ASP models

  12. Networks2 • Type • Domain controlled • Peer-to-peer • Router/Firewalled • NAT-192.168.x.x • Network Printer • Storage • Local • Server-USB/Firewire • Network Attached Storage-NAS • Remote-”Cloud”

  13. Basics • Use anti-virus and update • Windows updates-allow automatic • Open email attachments carefully • Make backups of important files • Use strong passwords • Use care in downloading programs • Limit file access with password/encryption
