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.
Navigation and Location
- 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.
