TCP and UDP are two different layer 4 protocols. TCP reliably sends data with acknowledgments and UDP sends data without checking if the destination received it. Skype uses UDP while email uses TCP.

Data Link Layer

Internal reflection

The PC sends out a broadcast ARP (Address Resolution Protocol) request before the first ping request to determine the MAC address of the target device corresponding to its IP address. Since IP communication requires the MAC address for packet delivery on a local network, the broadcast ensures that all devices on the network segment receive the request. The target device will respond with its MAC address, allowing the PC to encapsulate the ping request in Ethernet frames for proper transmission.

PAN = Personal Area Network

WAN = Wide Area Network

LAN = Local Area Network

____ is an updated, digital version of X.25 that also relies on packet switching.

The earliest modem I owned was 300 baud, but I remember earlier ones at 110 baud -- call it 110 bits per second. Divide by 8 to get about 14 bytes per second, which is roughly 14 characters per second, which is faster than most people can type.

No Computer Hardware and software are not same. The tangible or touchable parts of the computer is called hardware and the non tangible and non touchable parts are called the software But Both need assistance of each in processing. For example windows or Linux cannot run with hard drive or processor.
