computer networks classified into point to point and broadcast network
What are two advantages of using a router?
When using host, you need to turn on the host PC in order to connect via the internet or to other PC that's connected on the network unlike usin the router, you can turn on whichever PC you want. When the host PC hangs or have some technical problems, it affects the whole network is affected unlike using a router, when one PC had a problem the network will not suffer from it and still works accordingly.
What are the advantages of gateway?
a gateway can translate information between different networks data formats or network architecture. most gateways operate at the application layer. it can also be operated on network or session layer. by: talha jamal and farhan moin (kinpoe)
How many VLANs can be configured on a Cisco 2960 Switch?
The command "show vtp status" will show you how many vlans are supported by the switch. The Cisco 2950 switch supports up to 64 VLANs.
What type of tools are available for network management?
A network manager would like to have network management
capabilities when
(a) a component of the network fails,
(b) a component of the network is about to fail, and is acting "flaky"
(c) a component of the network has been compromised from a
security standpoint and is attacking the network, e.g., by
launching a DOS attack by flooding the network with packets,
(d) traffic levels exceed a certain threshold on a link, causing packets
to be dropped,
(e) everything is running smoothly (in order to know that everything is
running smoothly and there are no problems).
There are many additional reasons as well.
The concept of a network topology and the different types of topology?
A network topology refers to the geometric arrangement of the actual physical organization of the computers (and other network devices) in a network. Network Topologies: Bus All devices connected to a central cable, called the bus or backbone. Bus networks are relatively inexpensive and easy to install for small networks. Star All devices are connected to a central device, called a hub. Star networks are relatively easy to install and manage, but bottlenecks can occur because all data must pass through the hub. Ring All devices are connected to one another in the shape of a closed loop, so that each device is connected directly to two other devices, one on either side of it. Ring topologies are relatively expensive and difficult to install, but they offer high bandwidth and span large distance. Hybrid Group of star-configured workstations are connected to a linear bus backbone cable, combining the characteristics of the bus and star topologies. Wireless Devices are connected by a receiver/transmitter to a special network interface card that transmits signals between a computer and a server, all within an acceptable transmission range.

What's the difference between a switch and a router?
brief: A router essentially determines which way is the shortest or fastest in a network, and routes packets accordingly. It works at layer 3 of the OSI model, moving packets from one port to another based on L3 addresses - ie. IP addresses, IPX addresses, etc. A bridge connects one point to another in a network permanently. It works at layer 1 and 2 of the OSI model.
Collection of computers and devices connected together?
This is the definition of a computer network. Devices such as routers and bridges create logical network subnets and network domains that computers, printers, and other devices can connect with to join the network.
What are the projected trends from emerging developments in data communications?
Today's computers seem to be getting smaller and smaller. It is now possible to answer your phone through a watch device. It is also possible for many more people to work from home using their computers. Networking from home is part of everyday life for some people. Everything they need to know is right at their fingertips.
What is the default subnet mask for IPv4?
The submask indicates the division between the network id and the host information in an ipV4 address. The default subnet mask indicates the presence of a class A, B, or C based network (the default) without subnetting.
What are two ways an IP address can be assigned to a PC?
you don't assign one yourself, persay... They are more or less assigned for you. With dialup connections, each time you connect to your ISP they give you a temporary IP to use while you are connected. When you disconnect, that IP is thrown back into a pool of other IP's and ready for the next person who connects.
Broadband and higher connections use static IP's quite often because of their "always on" capabilities. Since they never disconnect they are going to be the only ones using it and are often assigned an IP by their provider/ISP. Once that IP is assigned they can use it to directly link websites, ftps, telnets, etc to a specific computer. In order to get it changed, you would have to contact the provider and talk with them.
[Or, if you have been granted control of your own public network, you may do this directly by choosing and assigning an IP address within your "owned" public subnet to the machine(s) you choose. Beware that this means you need to handle your own "routing, switching and security (usually your own firewall)". JMH]
We can assign ip address to the windows based computer using these steps .
Click Start, click Control Panel, click '''Network and Internet Connections, and then click Network Connections.'''
- Right-click the network connection that is connected to the private ICS network, and then click Properties.
- On the General tab, click Internet Protocol (TCP/IP) in the '''This connection uses the following items list, and then click Properties.'''
- On the General tab, click '''Use the following IP address. Configure the entries as follows: #* IP Address: The IP address you chose for this client (for example, 192.168.0.100). #* Subnet Mask: 255.255.255.0 #* Default Gateway: 192.168.0.1 #* Click '''Use the following DNS server addresses, and then type 192.168.0.1 in the '''Preferred DNS server box.'''''' '''
- Click Advanced, and then click the DNS tab.
- In the '''DNS suffix for this connection box, type MSHOME.NET.'''
- Click OK.
- Click OK.

Any IP (Internet Protocol) address can be assigned to a Linux machine with a single step using the 'ifconfig' command. You must be 'root' user to issue this command. As is clearly illustrated by the lengthy, over complicated sequence of steps in the answer above, assigning two Internet Protocol addresses to a single Ethernet interface on a Linux host is refreshingly simple and elegant...
ifconfig eth0 192.168.2.2 netmask 255.255.255.0
To bring the interface up or down, in the example above, it is interface eth0,
issue the command:
ifconfig eth0 up
or
ifconfig eth0 down
No wonder Linux and it's BSD (Berkeley Software Distribution) counterparts are
running the vast majority of the web servers on the Internet, besides the fact
Linux and friends are faster, more user friendly (IMHO anyway) and of course,
far more reliable (not to mention more powerful).
How the use of computer networks can improve communication for the individual?
My caterpillar kidnapped the man who had murdered Mr. Carrot who (believe it or not) was going to be the caterpillars tea so the caterpillar cried so much that his tears drowned the monkey so the gorilla squashed the caterpillar.
P.S. I'm flying evil rainbow firebreathing pineapples
What application protocol dynamically allocates IP addresses to hosts?
DHCP - Automatically provides client computers and
other TCP/IP-based network devices with IP
addresses
How do you set up a home office wireless?
You need to get a good wireless router (use google to find out which one will suit your purposes). Also you need existing internet connection (DSL, RoadRunner and so on). After that you need to connect your router to the modem using the lan cable included with the router. Use WAN port to connect the wire between the router and the modem. After that set wireless security (read the manual for your router).
Some ISP use MAC of your computer to grant access to internet, you might have use the option "Clone your PC MAC" for your router if you want to connect to internet.
What are the four basic procces of network layers?
1. packet ia addresed to proper destination.
2. packet is encapsulated with necessary data to deliver.
3. packet is routed through web of networks that can deliver it.
4. finally destination decapsulates it.
What is benefit of the computer network?
The benefits of being a computer networker include being able to work on your own network, work in advanced environments, and earn a respectable living. Those who are knowledgeable of networking often work for large companies which require constant network maintenance.
Most wireless routers also allow you to plug in 4 to 8 other Ethernet cables. It would not be a router otherwise, it would simply be a wireless access point. The cable connections are also faster than the wireless (at this point).
What is the purpose of network attached storage raid?
Network Attached Storage is short for NAS, which is computer storage connect to a network. RAID is a hard drive or storage container, which provide access to the file network.
