Study Notes
Binary Values
- A binary value has two states, represented as 0 or 1, exemplified by a simple light switch.
NFC Technology
- Near Field Communications (NFC) allows data exchange between devices in close proximity, commonly used in smartphones.
Shared Peripherals
- Scanner and printer are classified as shared peripherals that connect to a host device, allowing network sharing.
Communication Configuration Components
- Essential components for host communication on remote networks include IP address, subnet mask, and default gateway.
Factors for Choosing Network Media
- Considerations include the installation environment, desired data transfer rate, and distance between connecting hosts.
Server Classification
- A host is classified as a server primarily based on having server software installed, rather than hardware specifications.
Interference in UTP Cables
- Unshielded twisted-pair (UTP) cables may experience data throughput issues due to electromagnetic interference (EMI) and crosstalk.
Data Communication Protocols
- A data communications protocol establishes rules that govern the communication process between network devices.
MAC Address Definition
- A Media Access Control (MAC) address, assigned by manufacturers to Ethernet NICs, is a 48-bit physical address used locally.
Ethernet Switch Functionality
- An Ethernet switch builds its address table by examining the source MAC address of incoming frames.
Bandwidth vs Throughput
- Bandwidth defines the maximum capacity of data transfer in a network, while throughput is the actual rate of data transfer achieved.
Private IP Addresses
- Valid private IP addresses fall within specified ranges, including 10.x.x.x, 172.16.x.x to 172.31.x.x, and 192.168.x.x.
Unicast Address in Subnet
- Under a default subnet mask, 192.16.43.67 is classified as a unicast address, while other addresses may represent network or broadcast addresses.
IPv6 Address Representation
- The full uncompressed representation of the IPv6 address 2001:DB8:0:0:AA::200 is 2001:0DB8:0000:0000:00AA:0000:0000:0200.
Domain Name Resolution
- The Domain Name System (DNS) resolves domain names to their corresponding IP addresses before resource requests are processed.
TCP/IP Protocol Sessions
- Port numbers are used by the TCP/IP stack to track specific application sessions, allowing multiple service requests.
Destination Port in Messages
- In client-server communications, the destination port number indicates which specific service is being requested from a server.
Ethernet Frame Size
- A standard Ethernet frame can encapsulate between 46 and 1500 bytes of user data, with specific fields added during encapsulation.
Transport Layer Protocols
- The User Datagram Protocol (UDP) offers best-effort delivery without guaranteed packet arrival, contrasting with TCP's reliability features.
Peer-to-Peer Networks
- In a peer-to-peer network, users can share resources, like printers, directly between their devices without a central server.
Intermediate Devices
- Routers, switches, and wireless access points are categorized as intermediate devices that facilitate data packet transfers in a network.
Packet Destination Determination
- A host checks the subnet mask to compare source and destination IP addresses, determining if the destination is local or remote.
Configuration Tasks
- Proper IP configuration for a device includes assigning a valid host IP address, appropriate subnet mask, default gateway, and DNS settings.
