The designers of a database typically begin by developing a​ Data model to construct a logical representation of the database before it is implemented.

What is a data model?

A data model  in database is a type of data model that determines the logical structure of a database. It fundamentally determines in which manner data can be stored, organized and manipulated. They are three primary data models namely: relational, dimensional, and entity-relationship (E-R).

Which is true of ASCII and Unicode?
allochka39001 [22]

Answer:

The correct options is;

Every character written in A S C I I can be represented using Unicode

Explanation:

All characters found in A S C I I can be found in Unicode such that A S C I I is a subset of Unicode whereby the meaning of the numbers from 0 to 127 are the same in both A S C I I and Unicode

The size of the A S C I I character in 8-bit A S C I I encoding is 8 bits while a Unicode U T F - 8 encoding has between 8 bits (1 byte) and 32 bits (4-bytes)

A S C I I assigns only 127 of the 255 possible numbers that can be stored in an 8-bits character, where the spare characters are then used by P C s for accented characters, therefore, it A S C I I does not define accented characters

8.10 Code Practice Question 3
Alchen [17]

terms = ["Bandwidth", "Hierarchy", "IPv6", "Software", "Firewall", "Cybersecurity", "Lists", "Program", "Logic",

        "Reliability"]

def swap(arr, in1, in2):

   w = arr[in1]

   arr[in1] = arr[in2]

   arr[in2] = w

print(terms)

swap(terms, 5, 1)

swap(terms, 2, 4)

swap(terms, 3, 5)

swap(terms, 5, 6)

swap(terms, 6, 8)

swap(terms, 8, 9)

print(terms)

This is how I interpreted the question. If I need to make any changes, I'll do my best. Hope this helps though.

Different types of connections are..

-A network is two or more devices connected through links.

-There are two possible types of connections: point-to-point and multipoint.

-A point-to-point connection provides a dedicated link between two devices.

Explain the different types of topologies

-Star network…
In star topology each device in the network is connected to a central device called hub. Unlike Mesh topology, star topology doesn't allow direct communication.

-Ring network…
A number of repeaters are used for Ring topology with large number of nodes, because if someone wants to send some data to the last node in the ring topology

-Bus network…
In bus topology there is a main cable and all the devices are connected to this main cable through drop lines. There is a device called tap that connects the drop 

-tree topology…
Tree topologies have a root node, and all other nodes are connected which form a hierarchy. So it is also known as hierarchical topology. This topology integrates 

-Computer network…
Ring Topology; Star Topology; Mesh Topology; Tree Topology; Hybrid Topology; How to select a Network Topology? Types of Networking Topologies.

-Mesh networking…
Ring Topology; Star Topology; Mesh Topology; Tree Topology; Hybrid Topology; How to select a Network Topology? Types of Networking Topologies.

Different type of networks

-Computer network…
Virtual Private Network (VPN). By extending a private network across the Internet, a VPN lets its users send and receive data.

-LAN…
Using routers, LANs can connect to wide area networks (WANs, explained below) to rapidly and safely transfer data. 3. Wireless Local Area Network (WLAN).

-Wide area network…
Wide area network, or WAN. In terms of purpose, many networks can be considered general purpose, which means they are used for everything from sending files etc.

-Metropolitan area network…
MAN or Metropolitan area Network covers a larger area than that of a LAN and smaller area as compared to WAN. It connects two or more computers that are apart.

-Wireless LAN…
WLAN (Wireless Local Area Network) helps you to link single or multiple devices using wireless communication within a limited area like home, school, or office 

-Wireless network…
A Wireless Local Area Network or WLAN is a network that is used to connect different devices without using wires etc.

-Storage area network…
Storage Area Network is a type of network which allows consolidated, block-level data storage. It is mainly used to make storage last longer etc.

-Personal area network…
PAN can be used for establishing communication among these personal devices for connecting to a digital network and the internet.

-Campus area network…
A Metropolitan Area Network or MAN is consisting of a computer network across an entire city, college campus, or a small region. This type of network is large.

Explain your own understand about protocol and standards

A protocol defines a set of rules used by two or more parties to interact between themselves. A standard is a formalized protocol accepted by most of the parties that implement it.

explain layers in OSI model

Physical, Data Link, Network, Transport, Session, Presentation, and Application.

Explain layers in tcp/ip model

Four layers of TCP/IP model are 1) Application Layer 2) Transport Layer 3) Internet Layer 4) Network Interface. ... It is also known as a network layer. Transport layer builds on the network layer in order to provide data transport from a process on a source system machine to a process on a destination system.

what are the peer to peer processing

In peer-to-peer (P2P) networking, a group of computers are linked together with equal permissions and responsibilities for processing data. Unlike traditional client-server networking, no devices in a P2P network are designated solely to serve or to receive data
