1.	The synchronous modems are more costly than the asynchronous modems because ?
	they produce large volume of data
	they contain clock recovery circuits
	they transmit the data with stop and start bits.
	they operate with a larger bandwidth
	Answer: they contain clock recovery circuits Explanation: Synchronous modems are more costly than asynchronous modems because they contain clock recovery circuits. Synchronous modems use a clock signal to synchronize the transmission of data between two devices. This allows them to transmit data at higher speeds and with greater efficiency than asynchronous modems, which rely on start and stop bits to signal the beginning and end of each data byte.

9.	If you want to connect to your own computer through the Internet from another location, you can use ?
	e-mail
	FTP
	instant message
	Telnet
	Answer: Telnet Explanation: Telnet is a protocol used to connect to remote computers over the Internet or a local network. It allows the user to access the command-line interface of the remote computer and execute commands as if they were sitting in front of it. Therefore, if you want to connect to your own computer through the Internet from another location, Telnet can be used. However, it's important to note that Telnet is an unencrypted protocol and can expose your login credentials to potential eavesdropping, so it's recommended to use a secure protocol such as SSH instead.
