FTP is the short form of File Transfer Protocol, while TFTP is the short form of Trivial Files Transfer Protocol. Both are used for transferring files. The major difference between FTP and TFTP is that the transmission of files by both protocols does not go the same way. FTP is a network protocol used to transfer files using Transmission Control Protocol or internet protocol network. Although this can be used in an anonymous way, you can still decide to create a password for authentication purposes.

TFTP, on the other hand, is also a network protocol used to transfer files. But the only difference here is that it does not require the use of a password to authenticate your identity. However, TFTP can only be used to transfer files that are not up to 1 terabyte. Whereas FTP can be used to transfer files that are more than one terabyte, the only problem here is that if you are using FTP anonymously, the amount of files that can be transferred is limited.

First, you must know what VPN stands for, which is a virtual private network. PPTP and L2TP are popular virtual private network security tunneling protocols. These protocols establish fast and secure connections between two endpoints. PPTP is the most widely chosen method for running your VPN. Most Internet service providers want L2PT for VPN because the encryption level is higher at 256 bits; however, the speeds are slightly slower the PPTP, which is only 128 bit encrypted.


L2TP would be recommended for businesses, doctors’ offices, and places like that because it requires greater security due to the professional component. But for home use, the PPTP is fine for personal use, and it is encrypted enough to keep you happy and protected.

IPSEC or Internet Protocol Security authenticates and encrypts data that are sent over an Internet Protocol network as it functions as a secure network protocol suite. GRE or Generic Routing Encapsulation, on the other hand, is used to send IP packets from one network to another without being treated like IP packets while the IPSEC cannot.

In IPSEC, information is transferred from the user to the host just like in the GRE but no one from the connection can look or eavesdrop from the exchange of communication. The use of GRE is faster compared to IPSEC but IPSEC offers a more secure connection, thus, personal information is safer compared to GRE.

There are two standards used for most new e-mails. SMTP is the acronym for simple mail transfer protocol, and POP stands for Post Office Protocol. POP is a protocol for the storage of e-mail, whereas SMTP is a protocol for sending and receiving.

SMTP is like a letter carrier or mailman where the person can deliver or pick-up mail for transfer to another location. POP can be compared to a mailbox or a post office box. It is the location in which the mail is delivered and where it resides until the recipient is ready to read it. SMTP is the standard by which mail is transferred on the internet.

SMTP means Simple Mail Transfer Protocol. IMAP means Internet Access Message Protocol. SMTP is very effective when you are trying to forward messages to a mail client while IMAP can be very helpful when you would like to manage and retrieve emails from the server. A lot of times, SMTP and IMAP must work together so that servers and recipients will be able to send and get messages easily.

Usually, the email will be sent through your chosen email client and SMTP will send the message to the email address of the recipient. If the sending is a success, the IMAP will place the email to the recipient so that it can be checked.

SSL stands for Secure Sockets Layer. This is typically used to make sure that the connections that people may have on the internet are more secure. It will be useful to ensure that the security of people are safe when they check out certain websites. SSH is a bit different because while it also makes sure that the connection is more secure, it also provides encryption.

It makes sure that the data will be secure even from eavesdropping. People make it a point to install the SSH on a remote device because they know that this will help in improving the security of the network’s connection. People can usually decide between the two if they are creating a website.

The meanings of these two are different. OSFP stands for Open Shortest Path First. BGP means Border Gateway Protocol. The main difference between the two is that OSFP is a type of intradomain routing protocol, while OSFP is an interdomain routing protocol.

OSFP makes sure that the routing will be within its system. BGP will allow routing to take place between two different autonomous domains. The implementation of OSFP is also known to be easier as compared to the BGP. It would take time, and a lot of effort before BGP can be correctly placed and used. The OSFP will also require a hierarchical network to work while the BGP would need a meshed network.

No, you cannot locate a device using the MAC address. The MAC address is the hardware address. If you have to, you can use it to find the IP address of your devices with the help of ARP tables, but that is it. If it is on your network, you can look up your device in network traffic or in the DHCPP logs.

However, the address will only point to the IP address the device is connected to rather than the actual location of the device. However, if you have signed in to Gmail or apple id on your device you can use them to locate your device and control its info from other computers.
