What is a computer network? - ✔✔A computer network is a group of computer systems and
|| || || || || || || || || || || || || || ||
other computing devices that are connected by a physical communication medium such as
|| || || || || || || || || || || || || ||
a wire, radio wave, or light beam.
|| || || || || ||
What is the purpose of a computer network? - ✔✔The purpose of a computer network is to
|| || || || || || || || || || || || || || || || ||
facilitate communication and resource sharing among a wide range of computing devices.
|| || || || || || || || || || ||
Give three examples of an Internet application? - ✔✔Email, web browsing, file upload and
|| || || || || || || || || || || || || ||
download, audio and voice telephone calls, distributed database, and video
|| || || || || || || || || ||
teleconferencing.
How are messages from different sending hosts transmitted over a packet switching
|| || || || || || || || || || || ||
network? - ✔✔Messages are subdivided into small blocks called packets that include the
|| || || || || || || || || || || || ||
identity of the receiving host. These packets are sent one after another on the same
|| || || || || || || || || || || || || || ||
communication medium and the system allows other senders to send their own packets || || || || || || || || || || || || ||
before the first sender can transmit the next packet.
|| || || || || || || ||
What are the three major categories of networks and what are their characteristics? -
|| || || || || || || || || || || || || ||
✔✔Local Area Network (LAN): is a computer network that interconnects computers within
|| || || || || || || || || || ||
a limited area such as a residence, school, laboratory, university campus or office building.
|| || || || || || || || || || || || || || ||
Metropolitan Area Network (MAN): spans a major city. || || || || || || ||
Wide Area Network (WAN): covers a larger geographic distance, and also generally involves
|| || || || || || || || || || || ||
leased telecommunication circuits or internet links.

What is the family of networking technologies commonly used in wired LAN? -
|| || || || || || || || || || || || ||
✔✔Ethernet
What is the technology used for wireless LAN? - ✔✔Wi-Fi
|| || || || || || || || ||
How do you connect a computer to a wired LAN - ✔✔By using a Network Interface Card
|| || || || || || || || || || || || || || || || ||
(NIC)
How do you connect a computer to a wireless LAN? - ✔✔By using a Wireless Network
|| || || || || || || || || || || || || || || ||
Interface Card ||
What is the MAC address of a computer? - ✔✔It is the 48-bit address that is assigned to the
|| || || || || || || || || || || || || || || || || || ||
NIC of that computer.
|| || ||
What are the two parts of a MAC address? - ✔✔The left-most group of 3 bytes (in hex) is
|| || || || || || || || || || || || || || || || || || ||
assigned by IEEE and is used to identify the manufacturer of the NIC. This is referred to as
|| || || || || || || || || || || || || || || || || ||
the Organizationally Unique Identifier (OUI).
|| || || ||
The right-most group of 3 byte (in hex) is assigned by the manufacturer to identify a
|| || || || || || || || || || || || || || || ||
particular NIC. ||
What is an internetwork or internet? - ✔✔An interwork or internet consists of two or more
|| || || || || || || || || || || || || || || ||
networks connected to one another by using a computer device called a router.
|| || || || || || || || || || || ||
What is the network protocol stack used on most internets? - ✔✔TCP/IP
|| || || || || || || || || || ||
How are computers identified on a computer that uses the TCP/IP protocol stack? - ✔✔By
|| || || || || || || || || || || || || || ||
using their IP address
