Chapter 6 Networks

1. CON

   • Networks have to be administered
   • Can be difficult to troubleshoot

2. IP Addressing

   • Transmission Control Protocol /Internal Protocol(TCP/IP)
   • An IP address is a number that is used to identify the device on the network
   • IPv4-conisits of a series of 32 binary bits(ones and zeroes).When a host is configured with the IPv4b address
   • IPv4-Working with 128-pit numbers is difficult.the 32 hexadecimal values are further subdivided into eight fields of four hexadecimal values

3. Networks

   • LAN-local area networks,
   • WLAN-wide local area network
   • PAN-personal area network
   • WAN-wide area network

4. Features and Benefits

   • Require Fewer peripherals-The figure shows that many devices can be connected to a network
   • sharing resources-Files,Application,Modems,Scanners and Printers
   • Increasing Communication-network provides serveal different collaboration tools

5. PRO

   • Peripherals can be shared
   • Networks allow groups access to documents

6. Bandwidth

   • b/s-bits per second
   • kb/s-kilobits per second
   • Mb/s-megabits per second
   • Gb/s-gigabits per second

7. Data transmission

   • Half Duplex-sends and receive,but not at the same time
   • Full Duplex-can send and receive at the same time
