Study Notes
Transmission Media
- Optical fiber provides the highest transmission speed in a network.
Data Link Layer
- The data link layer does not handle channel coding.
- The media access control sublayer manages medium-specific data link functions.
CRC
- CRC stands for cyclic redundancy check.
Network Layer
- The network layer deals with data packets.
- A 4-byte IP address consists of a network address and a host address.
- The internet protocol is the network layer protocol for the internet.
Transport Layer
- TCP and UDP are transport layer protocols.
Network Topologies
- Bus topology uses a multipoint connection.
- A Local Area Network (LAN) covers a building or campus.
Multiplexing
- Multiplexing is the sharing of a medium and its link by multiple devices.
RIP Routing Protocol
- RIPv1 routers broadcast their routing tables every 30 seconds by default.
- The command
Debug IP ripdisplays RIP routing updates. - RIP protocol provides a full route table update every 30 seconds.
- The default administrative distance of RIP is 120.
Classless Routing Protocols
- Classless routing protocols allow variable length subnet masks.
- RIPv2 supports classless routing.
Routing Protocols
- RIPv2 and IP EIGRP can be redistributed into OSPF.
Routing Protocol Selection
- RIPv2 should be selected for networks with diameters exceeding 17 hops.
URL
- URL stands for uniform resource locator.
IP Protocol
- IP is connectionless and unreliable; it does not offer error reporting, reliable service but does offer error reporting.
IP Address Classes
- Class F is not a class of IP address.
IPv6
- IPv6 uses a 128-bit address.
- IPv6 does not use broadcast addresses.
- IPv6 features include anycast addresses but not fragmentation or header checksum.
Subnetting
- A subnet mask of 255.255.255.224 can be used for subnets with at least 16 hosts each.
- For example, the subnet ID for 172.16.66.0/21 is 172.16.64.0.
/19 Subnet
- The /19 subnet (172.16.0.0) provides 8 subnets and 8,190 hosts each.
ICMP
- The Internet Control Message Protocol (ICMP) handles error reporting and host/management queries.
- ICMP error messages are sent to the source of a datagram.
- ICMP error messages are not generated for datagrams with special addresses like 127.0.0.0.
