Which of the following is correct about a peer-to-peer network?
-
Centralised administration
-
Everyone has the same virus definitions
-
There is no centralised data storage
-
The more PC's that are added, the easier they are to manage
Correct Answer
A. There is no centralised data storageExplanation
A peer-to-peer network is a type of network where all devices have equal capabilities and responsibilities. In this type of network, there is no central server or central storage location for data. Instead, each device in the network can act as both a client and a server, allowing for direct communication and file sharing between devices. This decentralized approach to data storage means that each device is responsible for storing and managing its own data, eliminating the need for a central storage location.Rate this question:

The information a DHCP server can assign to hosts is? (Choose 3 )
-
IP address
-
Default gateway
-
HTTP
-
Subnet Mask
-
Reltentext
Correct Answer(s)
A. IP address
A. Default gateway
A. Subnet MaskExplanation
A DHCP server can assign IP addresses, default gateways, and subnet masks to hosts. IP addresses are necessary for devices to communicate with each other over a network. A default gateway is the IP address of the router that connects a local network to other networks. It is used to forward network traffic between different networks. Subnet masks determine the network portion and host portion of an IP address, allowing devices to identify which network they belong to and which hosts are on the same network.Rate this question:

Correct Answer
A. Used by small networksExplanation
A class C IP address is typically used by small networks. Class C addresses have a range of 192.0.0.0 to 223.255.255.255, with the first octet always starting with a number between 192 and 223. These addresses provide a relatively small number of available network addresses, making them suitable for smaller networks such as home networks or small businesses. Large networks typically require more available addresses and therefore use class A or class B IP addresses.Rate this question:

How does CSMA/CD known when to send data on the network?
-
Uses a token system to have its turn to send information
-
Listens for when the network is clear to send information
-
Sends information when it wants, and re-sends if it collides
-
Sends information when it wants, the network can handle it
Correct Answer
A. Listens for when the network is clear to send informationExplanation
CSMA/CD (Carrier Sense Multiple Access with Collision Detection) is a protocol used in Ethernet networks to ensure that multiple devices can share the same network without causing collisions. In order to avoid collisions, CSMA/CD listens for when the network is clear to send information. It first checks if the network is idle, meaning no other device is currently transmitting data. If the network is clear, it sends its own information. However, if it detects another device transmitting at the same time, it aborts its transmission and waits for a random amount of time before attempting to send again. This process helps to minimize collisions and optimize network efficiency.Rate this question:
