What is the protocol design of BGP?

Border Gateway Protocol (BGP) is designed as an exterior gateway protocol used to exchange routing information between different autonomous systems (ASes) on the Internet. BGP operates based on a path vector routing algorithm, where routers exchange network reachability information along with a list of AS numbers that the route traverses. This design allows BGP to … Read more

What is the default gateway and default route?

The default gateway, also known as the default route, is a critical network configuration setting that specifies the router or gateway device used by a networked device to access destinations outside its own subnet or local network segment. When a device needs to communicate with a destination IP address that is not within its own … Read more

What is the role of TCP IP in the Internet?

TCP/IP (Transmission Control Protocol/Internet Protocol) serves as the foundational suite of protocols that enables communication and data exchange across the Internet. Here’s its role and contributions: TCP/IP plays a crucial role in facilitating reliable and orderly communication between devices connected to the Internet. TCP (Transmission Control Protocol) is responsible for ensuring reliable data delivery by … Read more

What is the subnet mask option?

The subnet mask option in networking refers to a configuration setting that defines the boundaries (or subnet) of a network segment. It is a 32-bit number typically expressed in dotted-decimal notation (e.g., 255.255.255.0) that accompanies an IP address. The subnet mask determines which portion of an IP address identifies the network and which portion identifies … Read more

How does SCP work?

SCP, or Secure Copy Protocol, is a network protocol used for securely transferring files between a local host and a remote host or between two remote hosts. SCP operates over SSH (Secure Shell) protocol, utilizing encryption to ensure data confidentiality and integrity during file transfers. It combines the capabilities of remote login and file transfer … Read more

What are the methods of subnet masking?

Subnet masking methods primarily revolve around different techniques for configuring subnet masks to divide IP address space into smaller, manageable subnets within a network. The main methods include: Classful Subnetting: Based on the original class-based IP addressing scheme (Class A, B, and C), where subnet masks are predetermined depending on the class of the IP … Read more

What is the difference between NTP 3 and NTP 4?

NTPv3 (Network Time Protocol version 3) and NTPv4 (Network Time Protocol version 4) differ primarily in their features, improvements, and capabilities: NTPv3 was an earlier version of the Network Time Protocol, standardized in RFC 1305. It introduced the foundational concepts of time synchronization over networks, defining basic operations such as how clients query time servers … Read more

What is 255.255 255.0 subnet notation?

The subnet notation 255.255.255.0 represents a subnet mask in dotted-decimal format, commonly used in IPv4 networking to define the size and boundaries of a subnet. Each octet (segment separated by dots) in the subnet mask specifies eight bits, totaling 32 bits for IPv4 addresses. In this notation: The first three octets (255.255.255) are all set … Read more

What is the file system in network security?

File system in network security refers to the structure and organization of files and directories within a network environment, managed to ensure confidentiality, integrity, and availability of data. It involves implementing access controls, encryption, auditing, and monitoring mechanisms to protect against unauthorized access and data breaches. File system refers to the method used by an … Read more

How does SNTP work?

SNTP, or Simple Network Time Protocol, is a simplified version of the Network Time Protocol (NTP) designed to provide time synchronization for networked systems with reduced complexity and resource requirements. Here’s how SNTP works: SNTP operates on the client-server model, where client devices (such as computers or network devices) synchronize their clocks with a designated … Read more
