Collision Feee tolopology within the ring topology is called a ______

Explanation
In a collision-free topology within a ring topology, the data transmission is organized in a sequential manner, where each node takes turns sending frames without any collisions. This ensures that only one node is transmitting at any given time, preventing any data collisions. Therefore, the correct answer is "Frame, Series, node" as these terms relate to the collision-free transmission process within a ring topology.

In a mesh topology what is one draw back?

Takes a long time to set up
Requires many Physical connections
One node going down means system is broke
Central hub goes down mean they all go down

Correct Answer

A. Requires many Physical connections

Explanation

In a mesh topology, one drawback is that it requires many physical connections. This means that a large number of cables and connections are needed to establish the network, which can be time-consuming and expensive to set up. Additionally, the maintenance and management of these physical connections can also be challenging.

What is at the top of the hierachy of a heirachical tapology?

A node
Bus
Rootnode

Correct Answer

A. Rootnode

Explanation

In a hierarchical topology, the root node is at the top of the hierarchy. It is the central point that connects all other nodes in the network. The root node controls and manages the entire network, making it the highest level in the hierarchy. The other nodes are connected to the root node and are dependent on it for communication and network access. Therefore, the correct answer is rootnode.

What are the main components of a network?(3)

Resource
Client
Hub
Server
Rooter
Nodes

Correct Answer(s)

A. Resource
A. Client
A. Server

Explanation

The main components of a network are resources, clients, and servers. Resources refer to any device or software that can be accessed over the network, such as printers or files. Clients are the devices or software that request and use the resources, such as computers or smartphones. Servers are the devices or software that provide the resources to the clients, such as file servers or web servers.

In the OSI model, OSI stands for?

Operating Systems Interconnect
Outdoor Systems Internet
Open Systems Interconnect
Open Sound Instruments

Correct Answer

A. Open Systems Interconnect

Explanation

The correct answer is "Open Systems Interconnect." The OSI model is a conceptual framework that standardizes the functions of a communication system into seven different layers. These layers help in understanding how different protocols and technologies work together to enable network communication. The term "Open Systems" refers to the ability of different systems to interconnect and communicate with each other, while "Interconnect" emphasizes the interconnected nature of these systems. Therefore, "Open Systems Interconnect" accurately represents the purpose and essence of the OSI model.

Within the OSI model put these layers in order from closest to user as number 1 to the bottom, Presentation Layer Transport Later Session Layer Data Link Layer Physical Layer Network Layer Application Layer

11.

The application layer protocol is ?

Html, ssl.
Tcp, usp
Ssl, mime
Tcp, rtp
Http, dhcp

Correct Answer

A. Http, dhcp

Explanation

html (hyper text markup language) authoring language to create files on the www
dhcp (dual host configuration protocol) defines dynamic ip addresses on a network

Can you describe the presentation layer?

Closest to the user
Provides mapping
Finds routes through different nodes
Controls connections through computers
Protocol = http, dchp
Protocol = ssl, mime
Protocol = tcp, rtp

Correct Answer(s)

A. Provides mapping
A. Protocol = ssl, mime

Explanation

provides mapping
ssl = secure sockets layer - transmits files over the inter net using keys to encriypt data \
mime (multipurpose internet mail extensions) format non ASCII messages to send over internet

Describe the Transport Layer

Prototcol = TCP
Protocol = IpV
Protocol = rtp
Protocol = udp
Controls the flow control between two nodes
Manages Pacing of data
Controls connections between two computers
Finds routes through different nodes

Correct Answer(s)

A. Prototcol = TCP
A. Controls the flow control between two nodes
A. Manages Pacing of data

Explanation

tcp, = transmission control protocol
udp = user datagram protocol

16.

Correct Answer(s)

A. Protocol = IpV
A. Finds routes through different nodes
A. Establishes route from sender to reciever

Explanation

The network layer within the OSI model is responsible for finding routes through different nodes and establishing a route from the sender to the receiver. This is achieved through the use of the Internet Protocol version (IPv) which is designed to handle the addressing and routing of data packets across a network. IPv enables the network layer to determine the most efficient path for data transmission and ensure that it reaches its intended destination.

What does dhcp stand for?

Dual host configuration protocol
Dynamic host configuration protocol
Dynamic host computer protocol
Dynamic host configuration pacing

Correct Answer

A. Dynamic host configuration protocol

Explanation

DHCP stands for Dynamic Host Configuration Protocol. This protocol is used to automatically assign IP addresses and other network configuration settings to devices on a network. It allows for easy management and allocation of IP addresses, making it efficient for network administrators to control and configure network settings. The other options mentioned in the question, such as dual host configuration protocol, dynamic host computer protocol, and dynamic host configuration pacing, are not correct explanations for the acronym DHCP.

The automatic allocation with dhcp addressing has a _ in order to give the client the _ IP address as last last time. The static allocation with dchp has a database of the clients _ and _ gives the same IP address if the _ is in the database

Correct Answer
database, same, LAN, MAC

Explanation
In automatic allocation with DHCP addressing, the DHCP server maintains a database of IP addresses that have been assigned to clients. When a client requests an IP address, the DHCP server checks the database to see if the client's MAC address is already in the database. If it is, the DHCP server assigns the same IP address that was assigned to the client last time. This ensures that the client receives the same IP address as before. On the other hand, in static allocation with DHCP, the DHCP server also maintains a database of clients' MAC addresses. If a client's MAC address is in the database, the DHCP server assigns the same IP address to the client, regardless of whether it was the last address assigned or not.
