In a bus topology, how many nodes can transmit at one time?
Correct Answer
A. 1
Explanation
In a bus topology, only one node can transmit at a time. This is because all nodes are connected to a single communication line, known as the bus. When a node wants to transmit data, it sends the data onto the bus. Other nodes on the bus receive the data, but only the intended recipient processes it. This prevents multiple nodes from transmitting simultaneously and causing data collisions. Therefore, in a bus topology, only one node can transmit at any given time.
2.
Collision Feee tolopology within the ring topology is called a ______
Correct Answer
Frame
Series
node
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.
3.
In a mesh topology what is one draw back?
Correct Answer
B. 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.
4.
What is at the top of the hierachy of a heirachical tapology?
Correct Answer
C. 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.
5.
What are the main components of a network?(3)
Correct Answer(s)
A. Resource
B. Client
D. 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.
6.
Define server?
7.
A Fat client will mainly use the server for the majority of its resources
Correct Answer
B. False
Explanation
False, the Thin client will use the majority of the resources
8.
A resource is?
9.
In the OSI model, OSI stands for?
Correct Answer
C. 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.
10.
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 ?
Correct Answer
E. 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
12.
Can you describe the presentation layer?
Correct Answer(s)
B. Provides mapping
F. 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
13.
Can you describe the session layer within the OSI model?
14.
Describe the Transport Layer
Correct Answer(s)
A. Prototcol = TCP
E. Controls the flow control between two nodes
F. Manages Pacing of data
Explanation
tcp, = transmission control protocol
udp = user datagram protocol
places the data in the correct order to the session layer managing the pace.
15.
Describe tcp
16.
Describe the network layer within the OSI model
Correct Answer(s)
B. Protocol = IpV
H. Finds routes through different nodes
I. 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.
17.
Describe the physical layer within the OSI model
18.
What does dhcp stand for?
Correct Answer
B. 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.
19.
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.
