A sales team which will be employing a new database is interviewed by a database designer. The designer records relationships and entities as nouns and verbs during the interview.

What is database?
In computing, a database is a structured set of data that is accessible and stored electronically. Large databases are housed on computer clusters or cloud storage, whilst small databases can be stored on a file system. Data modelling, effective data representation & storage, query languages, privacy and security of sensitive data, plus distributed computing challenges, such as providing concurrent access and fault tolerance, are all part of the design of databases.

In order to collect and process data, a database management system (DBMS) communicates with applications, end users, and the database itself. The primary tools offered to manage the database are also included in the DBMS software.

To become a registered nurse (RN), you must first obtain an Associate Degree in Nursing (ADN), followed by passing the NCLEX-RN exam.

Who is a registered nurse?

A registered nurse (RN) is a nurse who has completed a nursing programme and met the requirements for obtaining a nursing licence outlined by a country, state, province, or similar government-authorized licencing body. The scope of practise of a registered nurse is determined by legislation and regulated by a professional body or council. Registered nurses work in a wide range of professional settings and frequently specialise in a field of practise.

Although a BSN typically takes four years to complete, a few nurses with job experience and existing RN certification may be able to finish it faster by enrolling in an accelerated RN-to-BSN programme.

This data replicates such that it is identical everywhere. Engineers find that some replicas are updating slowly.

The practice of replicating data involves storing the same information in many places in order to increase data accessibility and availability as well as system resilience and dependability.

Data replication is frequently used for disaster recovery to guarantee that an accurate backup is always available in the event of an emergency, hardware failure, or system breach where data is compromised.

Data access can be accelerated by having a replica, especially in businesses with numerous locations. When accessing data from North American data centers, users in Asia or Europe could experience latency. Access times can be sped up and the burden on the network balanced system by placing a copy of the data close to the user.

Additionally, replicated data can optimize and enhance server speed.

A computer with a 4 million byte cache, 2 billion byte memory, 4 trillion byte drive.

What is byte?
A byte is a measure of digital information that typically has eight bits. The byte is the smallest addressable unit of memory in various computer systems because it was historically the amount of bits needed to encode a single character or text in a computer. Network protocol specifications like The Internet Protocol refer to the an 8-bit byte as an octet to distinguish them from the general notion of 8-bit bytes. Depending just on bit endianness, an octet's bits are typically counted from 0 to 7 or 7 to 0, respectively. Since the initial bit is a zero, the eighth bit is a seven. In the past, the byte's size was determined by the hardware, and there were no clear standards that prescribed it.

The long-term rate host a sends data to host b is 100 Mbps, Host A's sending rate can be at most 100 Mbps. Still, Host A sends data into the receive buffer faster than Host B can remove the data.

Transmission Control Protocol (TCP) means a standard that describes how to establish and maintain a network conversation by which applications can exchange data. TCP works with the Internet Protocol (IP), which describes how computers send packets of data to each other.

Based on the story above, the receive buffer fills up at a rate of roughly 40 Mbps. If the buffer is full, Host B signals to Host A to stop addressing data by setting RcvWindow = 0; Host A then stops addressing until it receives a TCP segment with RcvWindow > 0. Host A will start sending as a function of the RcvWindow values it receives from Host B and also thus repeatedly stop.

Fast recovery is used in instances where data needs to be recovered quickly from a backup. Fast recovery can be used in instances where data is lost or corrupted, or in instances where the system needs to be restored to a previous state.

What is fast recovery?
Fast Recovery is now TCP's final advancement. Every time network congestion is identified, the congestion window is reduced to 1 by using solely Fast Retransmit. As a result, reaching high link utilisation again takes some time. Fast Recovery, on the other hand, solves this issue by doing away with the slow-start period. Slow-start will specifically only be used at the start of a connection and once an RTO time has expired. The lack of slow-start after receiving three duplicate ACKs is due to the fact that triple ACKs inform the transmitting side of more than just packet loss. The dup ACK informs the sending side that packet has been missed by the network since the receiving side can only generate one if it gets an out-of-order packet.

What is mobile app?
A mobile application, sometimes known as an app, is a computer programme or software application that is meant to run on a mobile device such as a phone, tablet, or watch. Mobile applications are frequently distinguished from desktop programmes, which are intended to operate on desktop computers, and web applications, which are intended to run via mobile web browsers rather than directly on the mobile device. Apps were originally intended for productivity aids such as email, calendar, and contact databases, but public demand for apps resulted in rapid expansion into other areas such as mobile games, factory automation, GPS and location-based services, order-tracking, and ticket purchases, resulting in millions of apps now available. Many apps necessitate Internet access.

The Ping sweep type of scan being used is Network Scan which could result in an alarm being triggered or an attempt being blocked.

What type of scan is ping sweep?

You can use the network scanning technique known as ping sweep, often referred to as ICMP sweep or a ping scan, to discover which IP addresses correspond to active hosts. In contrast to a single ping, a ping sweep communicates with numerous hosts simultaneously using ICMP (Internet Control Message Protocol) ECHO requests.

What is ICMP?

When network issues prohibit the transmission of IP packets, network devices like routers employ ICMP (Internet Control Message Protocol) to emit error messages to the source IP address.

To search for active systems, a ping sweep is used to scan a set of IP addresses. A security system may also be informed by a ping sweep and the type of scan is a Network scan.
