Basic Information

• What is the Internet
  • The Internet is a global network of billions of computers and other electronic devices, decentralized networks
• Who and when invented the internet
  • Bob Kahn and Vint Cerf in 1983
• Who controls the internet
  • No one, it is decentralized
• What is the World Wide Web
  • all the public websites or pages that users can access on their local computers and other devices through the internet. A network of networks
• What is an ISP
  • A company that provides internet for you needs
• What is an IP
  • are the identifier that allows information to be sent between devices on a network
• What are common internet protocols (describe)
  • HTTP
    • Used for distributed information systems
  • FTP
    • Used for file transfer
  • DNS
    • Used for assigning names
  • SMTP
    • To sends and receive emails
  • SSH
    • Used for connecting Computers over the web
  • TCP
    • The Transmission Control Protocol is one of the main protocols of the Internet protocol suite. It originated in the initial network implementation in which it complemented the Internet Protocol. Therefore, the entire suite is commonly referred to as TCP/IP
  • IMAP
    • Internet standard protocol used by email clients to retrieve email messages from a mail server over a TCP/IP connection
  • DHCP
    • The Dynamic Host Configuration Protocol is a network management protocol used on Internet Protocol networks for automatically assigning IP addresses and other communication parameters to devices connected to the network using a client–server architecture
  • Gopher
    • The Gopher protocol is a communication protocol designed for distributing, searching, and retrieving documents in Internet Protocol networks
  • ADP
    • The Address Resolution Protocol is a communication protocol used for discovering the link layer address, such as a MAC address, associated with a given internet layer address, typically an IPv4 address. This mapping is a critical function in the Internet protocol suite
• How does the data travel over the internet
  • it is first broken up into smaller packets, which are then translated into bits. The packets get routed to their destination by various networking devices such as routers and switches.
• What is IpV4 and IpV6
  • IPv4 is the first widely used version of the internet protocol. It was released in 1983 and is still in use today. IPv4 addresses are 32-bit binary numbers represented as groups of four decimal digits separated by periods (dotted decimal notation). Example IPv4 address: 192.168.10.150 IPv4 allows for up to 4.3 billion unique addresses, but this is insufficient given the growing number of connected devices.
  • IPv6 is a newer version of the internet protocol. It was deployed in 1999 to address the limitations of IPv4. IPv6 addresses are 128-bit hexadecimal numbers represented as eight sets of 16 bits separated by colons. Example IPv6 address: 2001:0db8:85a3:0000:0000:8a2e:0370:7334 IPv6 offers over 1,000 times more unique addresses than IPv4. It also provides additional features for security, flexibility, and speed.
• why do we need IpV6
  • IPv6 provides a solution to address the global issue of depleting address spaces due to increased demand for IP addresses. It offers reliability, faster speeds, and enhanced capabilities
