Identify the Following Address Formats
Traceroute – A command-line troubleshooting tool that enables you to view the route to a specified host. This will show how many hops the packets have to travel and how long it takes. In Windows operating systems, the command used is “tracert”.
Common Networking Protocols
Here are the steps for troubleshooting a network
One of the most ever-present and ancient uses of the Internet and networking has been to provide remote access to networks or network resources.

SNMP: It (SNMP) is a mainstream convention for system administration. It is utilized for gathering data from, and designing, system gadgets, for example, servers, printers, centers, switches, and switches on an Internet Protocol (IP) system.
Data access controls are established to control how subjects can access data, what they can access with it, and what they can do with it once accessed. Three primary types of access control are discussed in this section. Mandatory Access Control (MAC)
The two law systems that form the basis of legal systems in most countries are:
Kerberos is a network authentication protocol created by the Massachusetts Institute of Technology (MIT) that uses secret-key cryptography. Kerberos has three parts: a client, server, and trusted third party (KDC) to mediate between them.
Types of Attacks Denial of Service (DoS) Smurf Fraggle SYN Flood Teardrop Distributed Denial of Service (DDoS) Ping Sweep Port Scan Salami attack Man-in-the-Middle Session or TCP Hijacking Replay Buffer Overflow Scareware and Ransomeware Password attack Covert channels Web Attacks SQL Injection – An injection of SQL query through input data from client to application (database)….

Follow @ASM_Educational In this lab we are trying to make our Cisco Router Act as a DHCP server , that is R1 will give ip address 10.10.10.0/24 to left side Pc and it will give the IP address 18.104.22.168/24 to right side of PC. The Goal is Prepare you for your Cisco CCNA Certification exam.
Authentication : The verification of a person’s identity – Helps protect against unauthorized access.
Optical disc drives use removable media to store and retrieve data, typically 5.25”.
No network connectivity?
Hard Disk Drives are nonvolatile (meaning they don’t lose data when power off) devices that store data, generally 3.5”. Types of HDD include:
RAID stands for Redundant Array of Inexpensive Disks. RAID 0 is striping, RAID 1 is mirroring , RAID 5 is striping with parity, RAID 10 is mirrored sets in a striped set. RAID 0 is not fault-tolerant. If RAID 1 uses two disk controllers, it is disk duplexing. Short… Read more »
Sound cards connect as x1 PCIe or PCI cards and normally have PC 99 color-coded 1/8” mini-jacks for I/O and speakers, and optical I/Os known as S/PDIF (example: TOSLINK). Alternatively referred to as an audio output device, sound board, or audio card. A sound card is an expansion card or IC for producing sound… Read more »
Video cards connect to motherboards by way of x16 PCIe (most common, typically black), AGP (brown), or PCI (white) expansion slots.
Random Access Memory (RAM) types include SDRAM, DDR, DDR2, DDR3, RDRAM and SODIMMs.
The Central Processing Unit (CPU) or processor takes care of all calculations.
Motherboards – Connect everything together. Typical form factors include ATX (most common), microATX, ITX, and BTX.
