RJ45 connector is a standardized physical interface for connecting Ethernet cables to network devices.
RJ45 connector has 8 pins and is commonly used for Ethernet connections.
It is used to connect computers, routers, switches, and other network devices.
RJ45 connectors are typically used with Cat5, Cat5e, Cat6, or Cat6a Ethernet cables.
There are various colors available for Cat 6 cables, including blue, green, red, yellow, black, and white.
Blue
Green
Red
Yellow
Black
White
Colour code straight is a standard method of connecting network cables in a consistent manner.
Colour code straight is used for Ethernet cables to ensure proper connectivity.
It follows a specific pattern of matching colours on both ends of the cable.
For example, in T568A standard, the colour code for straight cable is white-green, green, white-orange, blue, white-blue, orange, white-brown, brown.
Fiber optic is a technology that uses glass or plastic threads to transmit data as pulses of light.
Fiber optic cables are made up of thin strands of glass or plastic called fibers.
Data is transmitted through these fibers in the form of light pulses.
Fiber optic technology is known for its high bandwidth and fast data transmission speeds.
Examples of fiber optic applications include internet connections, telecommunication
LAN network stands for Local Area Network, which is a network that connects computers and devices within a limited area such as a home, office, or building.
LAN networks are typically used for sharing resources like printers, files, and internet access within a small area.
LAN networks are usually faster and more secure than wide area networks (WANs) because they are confined to a smaller geographic area.
Examples of LAN ...
I applied via Superset and was interviewed in Apr 2022. There were 3 interview rounds.
A network is a group of interconnected devices that communicate with each other. OSI layers are a model for understanding network communication.
OSI layers are a conceptual model for understanding how data is transmitted over a network.
There are seven layers in the OSI model, each with a specific function.
The layers are: Physical, Data Link, Network, Transport, Session, Presentation, and Application.
Each layer communica...
TCP is a protocol used for reliable transmission of data over networks.
TCP stands for Transmission Control Protocol.
It is a connection-oriented protocol that ensures reliable delivery of data packets.
TCP uses a three-way handshake to establish a connection between two devices.
It provides flow control, congestion control, and error detection and correction mechanisms.
TCP is used for applications that require reliable da...
IPv4 uses 32-bit addresses while IPv6 uses 128-bit addresses.
IPv4 allows for approximately 4.3 billion unique addresses while IPv6 allows for approximately 340 undecillion unique addresses.
IPv6 includes built-in security features such as IPsec while IPv4 requires additional security protocols.
IPv6 also includes features such as stateless address autoconfiguration and multicast addressing.
IPv4 headers are 20 bytes long ...
There are several types of networks, including LAN, WAN, MAN, WLAN, and VPN.
LAN (Local Area Network) - a network that connects devices within a small area, such as a home or office.
WAN (Wide Area Network) - a network that connects devices across a large geographical area, such as the internet.
MAN (Metropolitan Area Network) - a network that connects devices within a city or metropolitan area.
WLAN (Wireless Local Area N...

I applied via Walk-in and was interviewed before May 2022. There were 3 interview rounds.
OSI (Open Systems Interconnection) layer is a conceptual model that describes the communication functions of a telecommunication or computing system.
OSI model has 7 layers, each with a specific function
Each layer communicates with the layer above and below it
Layers are numbered from 1 to 7, with 1 being the physical layer and 7 being the application layer
Examples of layers include physical layer, data link layer, netwo...

Border Gateway Protocol
BGP stands for Border Gateway Protocol
It is a standardized exterior gateway protocol used to exchange routing information between different autonomous systems on the internet
BGP helps in determining the best path for data to travel between networks
It is commonly used by Internet Service Providers (ISPs) and large organizations to connect to multiple networks
BGP operates on TCP port 179
Routers are networking devices that forward data packets between computer networks.
Routers operate at the network layer of the OSI model
They use routing tables to determine the best path for data packets
Routers can connect different types of networks, such as LANs and WANs
Expected CTC (Cost to Company) for the position
ECTC stands for Expected Cost to Company
It includes salary, bonuses, benefits, and any other compensation offered by the employer
Candidates should provide their expected salary range based on their experience and skills
I applied via Job Portal and was interviewed in Nov 2024. There were 2 interview rounds.
I would like simple test
Normal communication check
A loop is a sequence of instructions that is continually repeated until a certain condition is met. An IP (Internet Protocol) address is a unique numerical label assigned to each device connected to a computer network.
A loop is used in programming to execute a block of code repeatedly until a specific condition is met.
There are different types of loops such as for loop, while loop, and do-while loop.
An IP address is us...
BGP, OSPF, and VPN are all protocols used in networking to facilitate communication and secure data transmission.
BGP (Border Gateway Protocol) is used to exchange routing information between different autonomous systems on the internet.
OSPF (Open Shortest Path First) is an interior gateway protocol used to find the best path for routing within a single autonomous system.
VPN (Virtual Private Network) is a technology tha...
