Transmission modes in computer networks

Transmission mode
Transmission mode means Transferring of data between two devices.It is of 3 types .These are -
(1)Simplex mode- 
Simplex mode of transmission is the simple method of communication.In this type of transmission ,data can be send only through one direction i.e, communication is unidirectional.In this type of transmission, receiver can not send a reply to the sender. Examples are Television remote , keyboard etc.
(2)Half-duplex mode- 
In half-duplex mode each station can both transmit and receive but can't do both simultaneously.It means when the sender sending data ,at that time receiver can't sends data to the sender.When one device is sending,the other can only receive . Example :-Walkie-talkie .

(3)Full-duplex mode-   
In this type of transmission ,both station can transmit and receive data simultaneously .It means whenever a sender is sending data to the receiver ,at that time receiver can be able to sending data to sender along with receiving data from sender.Example-Telephone network .

MAC Address

MAC stands for media access control. MAC address is also known as physical address or hardware address or BIA(burnt-in-address).BIA is generally written in Cisco router switches.physical address is generally written in laptop/pc.MAC address is generally written in Mobile. MAC address is globally unic.The MAC address of a device is different from other devices.Many people are thinking there is only one mac address of a device but it is actually wrong ,Because there is no mac address of a laptop .There is a Mac address of your NIC(network interface controller) ,which is connected to your laptop .                                (NIC) If you change your NIC,then the Mac address of your laptop will be changed.NIC is a separate hardware component present in your computer used to connect with the network (home network or internet).There are so many ways that you can connect your laptop with the network like...

What is SMTP ?

 SMTP  -SMTP stands for simple mail transfer   protocol. -SMTP is an application layer protocol. -The transfer protocol of SMTP is TCP(Transmission control protocol)    because TCP is a reliable and connection Oriented protocol.TCP gurantees e-mail delivery . -It uses TCP port 25. -A few webmail services like G-mail use   unofficial port 465 for SMTP. -SMTP requires each message in 7-bit   ASCII(American Standard Code for   Information Interchange ) format. -SMTP is used by the client to send mail to servers because SMTP is a push protocol.It is used to send mail from sender to senders mail server and it is also used to send mail to receivers mail server from senders mail server . - Recepient download the mail from the mail server using POP3 or, IMAP .They can also just view the mail on the server by using webmail. Some SMTP commands:  •HELO and EHLO:- Command that initiate a new protocol session...

Difference between Hub and Switch

Hub is a networking device which operates on physical layer of the OSI(open system interconnection) model whereas switch is also a networking device but it operates on data link layer of the OSI model .Hub is purely hardware  but switch is a device which is the combination of both software and hardware.Hub supports broadcast transmission whereas switch supports Unicast, multicast and broardcast transmission .Hub is having single collision domain whereas Every port of Switch is separate collision domain.Transmission mode of hub is half-duplex whereas transmission mode of switch is full-duplex.Hub can do only forwarding whereas Switch can be able to do both forwarding and filtering.Hub can't store MAC (media access control) address where as switch stores MAC address.
