Hi all,
yup one more posibility today ..... A possibility which is interesting .... A possibility which is now a capability .. no not my capability ... but the capability of ur computer to understand that it is virtual .. but the capability of the network u r on to understand, that it is real ..... but the capability of the virtual world u and I live in, to understand that sometimes we have to switch sides ...
Ports connect countries and also themselves .... But do you know they also connect two computers .... Well in the last post we said we connect two computers through two services called telnet and Ftp ..so then where does the PORT come from now ... well it comes from IANA ... lol ... IANA stands for Internet Assigned Numbers Authority .... Ports are used in the TCP/IP to name the ends of logical connections which carry long term conversations .... To keep in record of what a services a user is using .... IANA has assigned each service a port ..... This though not the part of a protocol to compulsarily acquire a service only on and from a specific port ... for instance PN 23 is assigned to telnet service for TCP connections .... But can can telnet on to any other port ..... like say PN 80 which is used for http connections ..... There also exists ports and services which arent controlled by IANA .... these are called registered services ... these ports are not subjected to any rules of specific nature ..they only provide some flexibilities if connected by sepcific services ....
In science of programming ports are usually called as sockets (sockets on my pc and ports are on yours).... the knowledge of various protocols ,services and their respective ports is very essential in socket programming ....... All ur softies which connect with the internet have to be configured to connect some socket or port ....
Now lets go to the interesting part .... things that wont google out easily ....... What is the speciality about the word PORT ..... The word port is synonymous to the port word used to describe connecting pins of our hardware devices ..... This has been done so to make a statement that anything from out side has to connect only through a port ..... even if it is a service component or hardware component ..... the second interesting part of the name port is that it is close to the word RE(PORT) ...... whenever u want to know about a user u just need the list his services and there u go u know all he is doing ..
Well thats it for this post .. this is just a beggining ...... this are just possibilities ..... wait for the happenings ...u will know and learn more ... but for now possibilities all that is possible ....
hold tite ....and keep waiting

bye for now
