3. 3 What is Network Network is a communication situation between two or more computers. This communication may be between two computers in the same office, or between two computers located at different contries. If these computers are located in the local area, this network is called as “Local Area Network” (LAN). For creating this network there should be ethernet card and necessary network cables. According to number of systems (computers, printers, etc.) some additional instruments may be needed (Hub, Switch) The basic utility of LAN is data sharing feature. You can use this feature in many ways. For example; whole personnel can use only one printer, can communicate with each other with a computer, one application may be used by more than one personnel at the same time period, etc. A GLANCE TO NETWORK BRIEFLY

4. 4 TCP (Transmission Control Protocol) / IP (Internet Protocol) In a network, All instruments must speak the same language to understand each ather. We call this language as Protocol. For realizing a communication, both side must accept and apply the requested protocol. TCP/IP is a family of protocols which contains more than one hundred information communication protocols. Since the most important members of this family are TCP (Transmission Control Protocol) and IP (Internet Protocol), this protocol is called as TCP/IP Protocol. A GLANCE TO NETWORK BRIEFLY

5. 5 TCP/IP Address In a network, all instruments must have and Adress to understand each other correctly. By loading TCP/IP protocol to a computer, an address is allocated for that computer to be defined. IP : 194.27.253.100 “11000010.00011011.11111101.01100100” in binary form. C omputers can not have the same IP addresses. A GLANCE TO NETWORK BRIEFLY

6. 6 The Simple Programs that Used for TCP/IP  IPCONFIG  PING  NETSTAT  TRACERT  ROUTE  NSLOOKUP  ARP Windows / Start / Run / cmd A GLANCE TO NETWORK BRIEFLY

7. 7 IPCONFIG IPCONFIG command gives us TCP/IP settings. For achieving the whole information you should use “ipconfig /all” command. For getting the possible commands which you can use with “ipconfig” you should use “ipconfig ?” command in the same screen. A GLANCE TO NETWORK BRIEFLY

8. 8 PING This command is used for controlling the communication accessibility by sending an echo to another IP address. A GLANCE TO NETWORK BRIEFLY

9. 9 NETSTAT This command is used for controlling the communication accessibility by sending an echo to another IP address. A GLANCE TO NETWORK BRIEFLY

10. 10 TRACERT This command is used for observing the packet’s route which is sent to receiver. By writing an IP address or a domain name, the way of sent data packet can be traced. This command also can be used for determining the speed of the line. The usage of this command is “tracert –d IP ADDRESS”. A GLANCE TO NETWORK BRIEFLY

11. 11 NSLOOKUP, name server lookup is a network administration command-line tool available for many computer operating systems for querying the Domain Name System (DNS) to obtain domain name or IP address mapping or for any other specific DNS record. nslookup IP or nslookup DomainName.

12. 12 A GLANCE TO NETWORK BRIEFLY Route Route is used to view and modify the IP routing table. Route Print displays a list of current routes that the host knows. Sample output from the route command is shown in "Troubleshooting IP Routing" later in this chapter. Route Add adds routes to the table. Route Delete removes routes from the host's routing table.

13. 13 FTP (File Transfer Protocol) FTP is used for providing file transfer between two computers. FTP is one of the firstly developed internet protocols. For connecting to a computer by FTP the following conditions must be provided;  The host computer must have a network connection and FTP Service.  IP Addres of the host computer that you want to connect  The username and the password must be known.

15. 15 LETS DO SOME FTP  Creta a File on your local computer called as c:\YourName.txt  Make an Ftp connection with 10.100.1.241  Username = anonymous  Password = anonymous  Put your file called YourName.txt here  Enter dir command and try to see your file there.  Process Completed Successfully.  Write bye/quit to end connection.
