Answer:
COAP is a web transfer protocol designed for use with constrained nodes and networks in the IoT. COaP is intended to allow simple, constrained devices to connect to the IoT even on the constrained networks with low bandwidth and availability. Its commonly used in M2M applications like smart energy and building automation.
Answer:
Answer:
PAT is a NAT extension that allows multiple devices on a LAN to be mapped to a single public IP address in order to conserve IP addresses. The edge device is given a single IP address by the internet service provider.
Answer:
The process by which a router assigns a public address to a computer group of computers within a private network is known as NAT. Multiple devices can now share a single public IP address. The term can also refer to various types of IP addresses and port translations.

A NIDS is a monitor network for malicious traffic. In order to analyze all traffic, including unicast traffic. NIDS usually require promiscuous network access. NIDS are noninterfering devices that monitor traffic. NIDS sniffs the firewall internal interface and sends alerts to a NIDS management server via the different network interfaces.

Answer:
HIDS is a network-based intrusion detection system that is similar to a traditional intrusion detection system. It can monitor and evaluate the computing system's internals as well as network packets on its network interfaces.

Security tools such as intrusion detection systems and intrusion prevention systems are examples of such defenses. IPS and IDS solutions use similar technology, but each performs a different function, occupies a different location in the network, and defends against different types of attacks. To better understand this relationship. So now let us check the difference between IDS vs IPS to better understand this topic.
IDS analyzes and monitors network traffic for signs that an attacker is attempting to infiltrate or steal data from your network by employing a known cyber threat. To detect the various type of behaviors such as security policy violations, malware, and port scanners. IDS systems compare current network activity to a known threat database.
An IPS is an active security system. It like the IDS attempts to identify potential threats by monitoring features of a protected host or network and can employ signature, anomaly, or hybrid detection methods.
Answer:
The firewall is the version specified by the router. All data packets entering or leaving the network are routed through the firewall, which determines whether they should be allowed or denied. All traffic must pass through the firewall, and only authorized traffic should be permitted. A powerful firewall is required.
A proxy server is a server that acts as a middleman or gateway between any device and the rest of the internet. A proxy receives and forwards connection requests before returning data for those requests. It uses the anonymous network id instead of the client's actual IP address so that the client's actual IP address cannot be revealed.

Answer:
IDS scan network traffic for signature that corresponds to known cyber attacks. IDS analyses it for signature matching known attacks and alerts you when something suspicious occurs.

SDN manages networks by decoupling the control and forwarding planes. Architects and administrators use software to configure and manage network functions from a centralized control point. This approach creates dynamic, agile, and scalable networks that use modern data center virtualized infrastructure to respond quickly to changing business requirements.
NFV decouples network function from proprietary hardware appliances and provides equivalent network functionality without requiring specialized hardware. These virtual network functions, which run on high-performance x86 servers, have the distinct advantage of being deployable on demand.
Answer:
NFV is a network architecture that aims to speed up service deployment and reduce costs for network operators by separating functions such as firewall and encryption from dedicated hardware and moving them to virtual servers, collapsing various functions into a physical server, and ultimately lowering overall costs. NFV enables various network operators to implement network policies without having to worry about where the function should be placed in the network or how traffic should be routed through these functions.

What is ZigBee?
What is Firewall?
The router-specified version is the firewall. All data packets entering or leaving the network are routed through the firewall, which determines whether or not to allow them. All traffic must pass through the firewall, and only authorized traffic should be allowed to pass. A strong firewall is required.
What is antivirus?
An antivirus is a program or application that protects users from malicious software downloaded from the internet, A Antivirus protects against both external and internal threats. It is only implemented in software and not in hardware.
4G stands for the fourth generation, and it refers to long-term evolution. Its primary goal is to provide more reliable mobile broadband internet for devices such as smartphones, tablets, computers, and laptops. Speed is much faster than 3G, so 4G is incredible in terms of speed and efficiency, and it has taken the mobile market by storm.
LTE stands for long-term evolution, & it is a high-performance air interface for mobile phone systems. It is the final step toward the fourth generation of radio technologies, which are intended to increase the capacity and speed of mobile telephone networks. While the previous generation of mobile telecommunication networks is referred to as 2G or 3G. LTE is marketed as 4G technology.
Cache memory and RAM both bring data closer to the processor, reducing response time latency. Learn why one can be faster, as well as another important factor in cache Vs RAM
What is RAM?
RAM is an abbreviation for random access memory. It enables users to perform data read and write operations. It is referred to as transferred memory because the data stored in it is only valid while the power supply is turned on.

What is Cache?
The cache is a small, fast memory component in a computer that sits between the CPU and the main memory. To make this argument work. The cache must be significantly faster than the main memory. This method is less expensive than using fast memory devices to implement the entire main memory.
Answer:
To transmit data over short distances, MMF uses multiple rays of light running at different refection angles at the same time. When compared to SMF multimode optical fiber has larger cores. Multimode fiber can transmit multiple light signal modes at the same time.
