TCP/IP Protocols

A Family of Protocols

TCP/IP is a large collection of different communication protocols based upon the two original protocols TCP and IP.

TCP - Transmission Control Protocol

TCP is used for transmission of data from an application to the network.
TCP is responsible for breaking data down into IP packets before they are sent, and for assembling the packets when they arrive.

IP - Internet Protocol

IP takes care of the communication with other computers.
IP is responsible for the sending and receiving data packets over the Internet.

HTTP - Hyper Text Transfer Protocol

HTTP takes care of the communication between a web server and a web browser.
HTTP is used for sending requests from a web client (a browser) to a web server, returning web content (web pages) from the server back to the client.

HTTPS - Secure HTTP

HTTPS takes care of secure communication between a web server and a web browser.
HTTPS typically handles credit card transactions and other sensitive data.

SSL - Secure Sockets Layer

The SSL protocol is used for encryption of data for secure data transmission.

SMTP - Simple Mail Transfer Protocol

SMTP is used for transmission of e-mails.

MIME - Multi-purpose Internet Mail Extensions

The MIME protocol lets SMTP transmit multimedia files including voice, audio, and binary data across TCP/IP networks.

IMAP - Internet Message Access Protocol

IMAP is used for storing and retrieving e-mails.

POP - Post Office Protocol

POP is used for downloading e-mails from an e-mail server to a personal computer.

FTP - File Transfer Protocol

FTP takes care of transmission of files between computers.

NTP - Network Time Protocol

NTP is used to synchronize the time (the clock) between computers.

DHCP - Dynamic Host Configuration Protocol

DHCP is used for allocation of dynamic IP addresses to computers in a network.

SNMP - Simple Network Management Protocol

SNMP is used for administration of computer networks.

LDAP - Lightweight Directory Access Protocol

LDAP is used for collecting information about users and e-mail addresses from the internet.

ICMP - Internet Control Message Protocol

ICMP takes care of error-handling in the network.

ARP - Address Resolution Protocol

ARP is used by IP to find the hardware address of a computer network card based on the IP address.

RARP - Reverse Address Resolution Protocol

RARP is used by IP to find the IP address based on the hardware address of a computer network card.

BOOTP - Boot Protocol

BOOTP is used for booting (starting) computers from the network.

PPTP - Point to Point Tunneling Protocol

PPTP is used for setting up a connection (tunnel) between private networks.

  Introduction Now that the Pro moniker has gone mainstream, it's Ultra that has come to represent the cream of the crop, and the Xiaomi Mi 11 Ultra can wear that badge proudly. Limited to its home market last year, the ultimate Mi has gone global this time around, and we're happy to have it for review today. We're torn whether it's the camera system's physical appearance that is more striking or the hardware inside. A simply massive raised area on the back looks bolted on, almost after the fact, it's hard to miss, and it's a great conversation starter even if it's not everyone's cup of tea. But its size is warranted - the main camera packs the largest sensor used on a modern-day smartphone, and next to it - two more modules unmatched in their own fields, in one way or another. Oh, and yes, there's also a display here - because why not, but also because it can be useful. There's a lot more than 1.1 inches of ...
