Study Notes

Internet and Data Transfer

  • Fast speed of data transfer over the Internet is due to packet switching, which divides data into smaller packets for efficient transmission.
  • GPS (Global Positioning System) technology allows users to get directions to almost any location in a city.

Online Banking

  • Online banking enables users to perform various tasks, such as paying bills, transferring money, and checking account balances.

Online Selling

  • One of the advantages of online selling is the ability to reach a global customer base.

OSI Model

  • The Network Layer (Layer 3) is responsible for dividing data into smaller portions known as packets.
  • The Network Layer decides where to send the datagram and passes it on to the Data Link Layer.
  • The Data Link Layer is responsible for accepting IP datagrams and transmitting them as frames over specific network hardware.
  • The Session Layer (Layer 5) is responsible for sending messages or streams of information to the Internet transport Layer Protocols.

Switching Methods

  • Circuit switching involves establishing a dedicated communication path before the actual data transfer.

Signal Conversion

  • Analog-to-digital conversion is the process of converting analog signals into digital signals.

Signal Representation

  • The frequency domain represents a signal in terms of frequency rather than time.

Signal Transmission

  • Multiplexing is the process of combining multiple signals onto a single transmission medium.
