Typical service mode
? C/s,client/server Architecture
– A resource or a function provided by the server
– Client uses resources or features

#####################################################
TCP/IP is the most widely supported communication protocol

? Three elements for communication between host and host
– IP addresses (IP address)
– Subnet mask (subnet mask)
– IP routing (IP router)

#####################################################
– IP Address: Uniquely identifies a single host in the network

? Address composition (dotted decimal):
– Total of 32 bits
– Represented as 4 decimal digits, in. Separated
? For general computer networks
–a class: 1 ~ 127 Net + Master + Master + Master
–b class: 128 ~ 191 Net + Net + Master + Master
–c class: 192 ~ 223 Net + Net + Net + Master

? Dedicated to multicast and scientific research
–d class: 224 to 239 multicast
–e class: 240 ~ 254 Scientific research

IP address by network bit and host bit

Landline Number: Area code-Number
Area code: Identification Area
010-12345678
0316-7351111

192.168.1.1-----> First Look at the first number for 192-----> belongs to Class C address Network + Net + Net + Master
192.168.1.2

192.168.1.1:192.168.1 area (network), host with number 1
192.168.2.1:192.168.2 area (network), host with number 1

Configure IP Address
? Operation Steps:
– Right-click the Desktop Network---> Properties---> Change adapter settings
– Double-click Local Area Connection---> Properties
– Double-click Internet Protocol version 4 (TCP/IPV4)------> Use the following IP address
– When the configuration is complete, click OK to finish

Configure IP Address: 192.168.1.1
Subnet Mask: 255.255.255.0

  子网掩码作用：区分以及标识IP地址的网络位与主机位                         以数字1表示IP地址的网络位                         以数字0表示IP地址的主机位      11000000.10101000.00000001.00000001  11111111.11111111.11111111.00000000  子网掩码表示：192.168.1.1/24      # 24个网络位

How IP addresses are configured:
1. Manual Configuration
2. Obtain the IP address automatically, the premise of the network is a DHCP server

command to view IP address information

Windows key + R = Start + Run

ipconfig  查看ip地址信息   exit   退出命令行界面

Test Communication Command Ping sends four requests by default

       ping测试是双向，有去有回

Windows operating system default firewall blocks ping operations

Two machines shutting down the firewall
– Right-click the Desktop Network---> Properties---> Windows Firewall (lower left corner)
– Turn Windows Firewall on or off---> Up and down select Close

Windows key + R = Start + Run

 ping    对方机器的IP地址     #测试通信 ping    192.168.1.2
