Study Notes
Cisco Certifications
- CCA: Cisco Certified Architect, highest level of Cisco certification.
- CCIE: Cisco Certified Internetwork Expert, advanced certification focusing on network engineering.
- CCNP: Cisco Certified Network Professional, validates skills in planning, implementing, and troubleshooting networks.
- CCNA: Cisco Certified Network Associate, foundational certification for networking.
- CCENT: Cisco Certified Entry Networking Technician, entry-level certification for basic networking knowledge.
Networking Concepts
- WAN: Wide Area Network, connects networks over large distances.
- IOS: Internetwork Operating System, the software used on Cisco devices.
- NAT: Network Address Translation, allows multiple devices on a local network to share a single public IP address.
Networking Protocols
- TCP: Transmission Control Protocol, ensures reliable communication through error-checking.
- UDP: User Datagram Protocol, provides faster communication without guaranteeing reliability.
- IP: Internet Protocol, responsible for addressing and routing packets across networks.
- ICMP: Internet Control Message Protocol, used for network diagnostics and error reporting.
- ARP: Address Resolution Protocol, maps an IP address to a physical MAC address.
- RARP: Reverse Address Resolution Protocol, maps a physical address to an IP address.
Subnetting Methods
- VLSM: Variable Length Subnet Mask, allows subnets of different sizes.
- CIDR: Classless Interdomain Routing, improves allocation and routing of IP addresses.
- FLSM: Fixed Length Subnet Mask, utilizes identical subnet sizes.
Subnet Calculations
- Total number of subnetworks: number of subnets created based on borrowed bits; determined by CIDR notation.
- Total number of subnetted hosts: derived from the remaining bits after subnetting.
- Total number of usable subnetted hosts: subtract 2 from the total subnetted hosts for network and broadcast addresses.
- Total number of hosts: calculated from remaining unused addresses per network, minus reserved addresses.
Networking Devices
- PVC: Permanent Virtual Circuits, a permanent connection in a network.
- SVC: Switched Virtual Circuits, temporary connections established on demand.
- CSU/DSU: Channel Service Unit/Data Service Unit, devices used to connect end-user equipment to a digital circuit.
Memory Types in Networking
- ROM: Read-Only Memory, non-volatile storage for firmware.
- RAM: Random Access Memory, temporary storage for data and running applications.
- NVRAM: Non-Volatile Random Access Memory, retains configuration information after power loss.
- TFTP Server: Trivial File Transfer Protocol Server, used to upload and download configuration files.
Equipment Terminology
- DCE: Data Circuit-Terminating Equipment, connects to the communication line from the service provider.
- DTE: Data Terminal Equipment, connects to the DCE and sends data over the network.
Networking Protocols Continued
- IPX: Internetwork Packet Exchange, a network layer protocol used primarily on early Novell networks.
