10+ Sohan Healthcare Interview Questions and Answers

WAN is a network that covers a large geographical area while LAN is a network that covers a small area.

• WAN stands for Wide Area Network while LAN stands for Local Area Network

• WAN covers a large geographical area such as a city, country or even the world while LAN covers a small area such as a building or a campus

• WAN is usually slower and more expensive than LAN

• Examples of WAN include the internet while examples of LAN include home or office networks

TCP/IP is a set of protocols used for communication over the internet. OSI layer is a model for network communication.

• TCP/IP is a suite of communication protocols used for transmitting data over the internet.

• It consists of two main protocols: Transmission Control Protocol (TCP) and Internet Protocol (IP).

• TCP ensures reliable transmission of data while IP is responsible for routing packets to their destination.

• OSI layer is a conceptual model for network communication that defi...read more

A network is a group of interconnected devices that can communicate and share resources.

• A network can be wired or wireless

• Devices on a network can share files, printers, and internet access

• Networks can be local (LAN) or wide area (WAN)

• Examples of networks include the internet, home networks, and corporate networks

TCP and SSL headers are used in network communication to provide reliable and secure data transmission.

• TCP header contains source and destination port numbers, sequence and acknowledgment numbers, and control flags.

• SSL header contains information about the SSL version, cipher suite, and other parameters for secure communication.

• TCP header is 20 bytes long, while SSL header size varies depending on the SSL version and cipher suite.

• TCP header flags include SYN, ACK, FIN, RST, a...read more

OSPF routing in broadcast is a method of routing in which OSPF packets are sent to all devices on a network segment.

• OSPF packets are sent to all devices on a network segment, regardless of whether they need the information or not.

• This method is used in networks where there are multiple routers on a single segment.

• Broadcast OSPF packets are sent using multicast addresses.

• This method can be less efficient than other OSPF routing methods, such as point-to-point or non-broadcast....read more

Types of ARP include ARP request, ARP reply, ARP probe, and ARP announcement.

• ARP request is used to find the MAC address of a device on the network.

• ARP reply is the response to an ARP request, providing the MAC address of the target device.

• ARP probe is used to check if an IP address is already in use on the network.

• ARP announcement is used to inform other devices on the network about a change in MAC address.

RSTP is a protocol used to prevent loops in a network by dynamically disabling ports.

• RSTP stands for Rapid Spanning Tree Protocol

• It is an improvement over STP (Spanning Tree Protocol)

• RSTP uses port roles (root, designated, alternate, backup) to determine which ports should be active

• It also uses port states (discarding, learning, forwarding) to prevent loops

• RSTP can detect and respond to topology changes faster than STP

Bangalore is a bustling city in southern India known for its IT industry, parks, and nightlife.

• Bangalore is the capital city of the Indian state of Karnataka.

• It is also known as the Silicon Valley of India due to its thriving IT industry.

• To spell the name, it's B-A-N-G-A-L-O-R-E. Contact number varies depending on the person or b...read more

IPv4 addresses are 32-bit numerical labels used to identify devices on a network, while IPv6 addresses are 128-bit numerical labels.

• IPv4 addresses are written in decimal format separated by periods (e.g. 192.168.1.1), while IPv6 addresses are written in hexadecimal format separated by colons (e.g. 2001:0db8:85a3:0000:0000:8a2e:0370:7334).

• IPv4 addresses have a limited address space, allowing for approximately 4.3 billion unique addresses, while IPv6 addresses have a significan...read more

Types of testing include functional, non-functional, regression, performance, and security testing. STLC includes planning, design, execution, and reporting.

• Functional testing ensures that the software meets the specified requirements.

• Non-functional testing checks the software's performance, usability, and security.

• Regression testing ensures that changes to the software do not affect existing functionality.

• Performance testing checks the software's speed, scalability, and stab...read more
