How do we measure data transmission speed? How is that different from how we
measure data storage capacity? - ANSWER✔✔Data transmission speed is
measured in bits per second - bps. Kbps = kilo bits per second ; Mbps = mega bits
per second. When we measure data storage capacity we always talk in terms of
Bytes (B). When talking about data transmission speed we talk in terms of bits (b).
, What does bandwidth mean? How do we measure bandwidth? -
ANSWER✔✔Bandwidth is the amount of data that can be transmitted over a
channel per unit of time. Technically, the range of frequencies that can be
transmitted. Bandwidth is measures in bits per second (bps).
Which has lower/higher bandwidth among these: Bluetooth, WiFi, Ethernet -

protocol defines the Internet. - ANSWER✔✔TCP - breaks data into packets and

world that agree to speak the same language (Protocol: TCP/IP). The web is a
service (subsystem) of the internet (Protocol: HTTP)
Intranets are designed to be open and secure internal networks that use internet
technologies and are accessible through web browsers. Inside an organization
typically set up as a LAN.
Extranets connect some of a company's resources with external organizations, such
as customers and suppliers. Typically create a VPN using the internet as its
backbones and relying on firewalls for security.
