For a laptop (or any computer) to receive signals from a satellite you must add a receiver card. This could be external (USB interface) or internal (PCMCIA for a laptop, PCI for a regular PC). The receiver card has to be fed signals from a satellite antenna or a satellite dish with amplifier converter, known as an LNB. You do not say what signal you want from the satellite. You can watch TV or download data using a satellite receiver card, for this you will need a subscription with a satellite ADSL provider, who will also offer you the card and the software.
A satellite communication simply bounces a radio or data wave to another satellite or a receiver on earth. Satellites all act as giant relays for data transmissions.
In generic terms, Telecom is communication of voice from the sender to receiver with the help of hardware and softwares. Datacom, is transfer of non voice (ie, data) from the sender to receiver with the help of hardware and software
Its called the internet
A reliable data transfer is one that is stable . For a reliable data transfer a connection oriented protocol is used. A connection oriented protocol is one that receives acknowledgement from the receiver before sending the further data.
Polling in satellite networks is electronic signally between satellites to see which one is going to send data. It also requires a receiver that is polled to see if it is ready to transmit data.
flow control is the technique for assuring that a transmitting entity does not overwhelm a receiving entity with data. The receiving entity typically allocates a data buffer of some maximum length for a transfer. When data are received, the receiver must do the certain number of processing before passing the data to higher level software. In the absence of flow control, the receiver's buffer may fill up and over flow while it is processing old data.

telecommunication is the transfer of voice/data from transmitter to receiver through wire/wireless
No, they're used to transfer info or data from one software/computer to another...
its an USART(universal synchronous and asynchronous receiver and transmitter) used for serial data transfer
