NIC/Media
What is a Network Interface Card
A circuit board or chip that enables a device to connect to a network.
What is IPv4?
Internet Protocol version 4
It is an older version if IP address that uses a 32-bit address to identify nodes on a network.
Describe three functions of the router.
A router assigns an IP address to a device when it is connected to it.
It transmits data packets to the correct destination/computer on a network
It connects local network to the internet
A set of rules that determine how data should be transmitted over a network.
What is the name of the identifier to is assigned to the NIC?
Media Access Control
How many bits IPv6 uses to create a single unique address
128 binary bits
Give three differences between a MAC address and an IP address.
A MAC identifies a device network interface card whereas an IP address identifies the location of the device on the network
A MAC address never changes while the IP address changes
A MAC address is 48 bit number but the IP address is 32 bit or 128 bit
A hardware or software that is monitors the traffic on your network and filter unwanted websites.
A firewall
What is MAC (Media Access Control) addressing format?
MM:MM:MM:SS:SS:SS A 48-bit address written in hexadecimal notation.
What does DHCP stand for?
Dynamic Host Configuration Protocol
IPv4 uses decimal notation while IPv6 uses hexadecimal notation
IPv4 uses 32 bits while IPv6 uses 128 bits
IPv4 supports manual configuration but IPv6 does not support manual configuration. Instead it uses autoconfiguration.
Which IPv4 class of IP address is most suitable to connect 500 computers on a local network?
Class B
What is the common wired LAN technology?
Ethernet
What is the version of the ip address 253.123.98.12?
Give three differences between dynamic ip address and static ip address.
Dynamic ip address changes periodically while static ip address remains unchanged until the user request a change.
Dynamic ip address is assigned automatically by the DHCP server while static is assigned manually by someone.
Dynamic is more secure than static
Give one reason why someone would set up a network.
To gain access to the internet
To share a printer
To share information easily
Identify 1 form of transmission media.
Wired (Ethernet cables) or Wireless (Radiowaves)
A small network in a home.
Local Area Network
Give one difference between a router and a switch
A switch has more ports than a router
A switch is only used in a wired network but router can be used in a wired/wireless network
How many devices can be included in a class C network
