Computer Networking
Computer networks are collections of computers which are connected together in order to communicate and transfer information. Questions about computer networks, networking protocols, and how to set them up belong here.

You can create a hierarchial network using pretty much any type of networking equipment. No special equipment is required or needed, although if you are building a massive network, do consider at least Gbit interfaces and thus CAT6 cables.
Why are you interested in Networking?
I am in love with Ict. An ict person without good networking experience is not too complete. And most of the jobs I do requires networking. I think is good for me to have it.
Are there requirements to have a DHCP?
A DHCP is a dynamic host control protocol. There are no requirements to actually have a DHCP however there are certain guidelines one should follow in order to prevent any potential failures within the system.
1) ACL (Access Control List) policy instructs the router to drop it. This is a "rule" configured intentionally by the router's administrator to control traffic.
2) The packed fails an RPF (Reverse Path Forwarding) check. This is when a packet arrives with a source address that doesn't make sense, and it appears like an attempt at malicious activity.
3) The input queue is full. This is basically a symptom of the router being overloaded.
4) The packet fails a basic sanity check, such as TTL (Time to Live) expiring, or failing a CRC (Cyclic Redundancy Check), although that is actually a Layer 2 function, not IP.
5) The packet has a requirement that the router is unable to accomodate. Examples of this would be a non-UDP encapsulated IPSec packet whos destination address requires translation, or a multicast packet arriving at a router that is not configured for multicast routing.
a passive hub does not regenerate the signal received only let it pass
Can you configure multiple as on single router using eigrp?
Yes; a router might be a border router between two areas of a network - for example, one configured for AS 100, one for AS 200. However, unless you do some additional configuration, no information will automatically be shared between the two areas. The configuration is related to "route redistribution".
Which countries carry the SMC networks?
SMC Networks is an onsite equipment developer. They organize gateways, routers, modems and home security. SMC Networks maintains company operations in the Americas, Europe, Africa, Asia-Pacific and Japan.
What is a best practice for VLAN design?
Local VLANs should not extend beyond the distribution layer.
In the electrical industry, there are a variety of different uses for electrical lugs. Electrical lugs help provide the supply and distribution of electrical current without creating any hindrance between the electrical cables they’re connecting. Electrical lugs are often used when it isn’t possible to permanently connect two wires. Some of their most common uses include connecting two or more electrical cables, as well as connecting fuse sockets, load switches, and electrical appliances. Traditionally, only one end of an electrical lug is used to connect a cable to an electrical device. One end of the lug is soldered, crimped, or welded to ensure it’s installed properly and the other end of the lug is connected to the device.
When it comes to finding high-quality electrical lugs for your application, contact the team from Greaves Corporation online today. You can also call them at 1 (800) 664-4505.
What hardware does a bus topology need?
A bus topology needs a trunk cable, which is a high speed central cable to which all the nodes can be connected. If the trunk cable breaks down, however, the whole network comes to a halt.
When does the lease of your ip address expire?
It depends on the DHCP server, it could be a few days or year or more.
What is meant by multi hop routing?
Routing is the process of deciding where to send signals in a network. Multi-hop routing involves sending signals through multiple stops instead of one long pathway.
Computer with internet access.
Network cables connected to each machine.
Program installed on each computer.
Why do link-state protocols converge faster than most distance vector protocols?
Distance vector protocols compute their routing tables before sending routing updates; link-state protocols do not.
What are the Functions of each ip address class?
In classfull addressing schemes each address class limited the total number of clients per network. Other than that, there are no particular functions for each address class.
Density of air at ntp condition?
NTP (20 degrees, 101.3kPa) 1.205 kg/m3
STP (0 degrees, 101.3kPa) 1.293 kg/m3
