Answer:
A modem modulates and demodulates electrical signals sent through phone lines, coaxial cables, or other types of wiring.
Answer:
When Patricia checks her email use:
POP3
TCP
IP
When Patricia brows a website and log in to post a comment use:
HTTP
TCP
IP
LDAP
Explanation:
Email protocol
Patricia starts to check her email, the email application uses the protocol POP3.
The protocol TCP makes a connection with the server and transport the data.
Patricia receives her emails with the protocol IP on her computer.
Website protocol
Patricia started to surf and the protocol HTTP makes a connection with the internet.
The protocol TCP makes a connection with the server and transport the data.
With the protocol IP, she receives the website data.
With the protocol LDAP, Patricia makes a login to post the comment.
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

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
