What is the best router tech support in US?
The best router technical support for each brand of router is the support team of each manufacturer. They provide their support services for free and know their products inside and out, so they are able to resolve any problems that arise.
In my professional experience, I have found TP-Link to be the most helpful and most willing to assist with any problems that have arisen, even going so far as to create a custom firmware version to resolve a unique configuration issue for one of my clients.
As far as brands of routers to avoid, in my experience Asus and Belkin routers have been the worst in terms of longevity and reliability. While other brands (even off-brands such as Buffalo) have their issues and are not as user-friendly or as stable as the top-tier brands (TP-Link, Cisco/Linksys, Trendnet, D-Link, Netgear), they at least tend to remain fully functional for years. Asus and Belkin routers, as I have found in various client environments--both business and residential, tend to start having problems in as little as six months, sometimes making it to a year or so and all have needed to be replaced within no more than three years due to complete failure (no power, no lights, dead as a doornail).
I hope this helps. If you have any other questions, feel free to drop me a line. If you happen to be in the northeast Kansas area, let me know and I will be glad to have my company give you professional assistance if you wish.
Do frames encapsulate packets?
Frames encapsulate packets. When a packet arrives at the data link layer, the entire thing, header, data, and all, is used as the data field of a frame. The entire packet is put in an envelope (the frame) so to speak (assuming it fits).

When files containing large amounts of information are compressed or zipped, they are moved and forced into a smaller space to conserve memory and protect the file(s).
What Are The Disadvantages of repeater?
It can't filter network traffic. Data, sometimes referredto as bits, arriving at one port of a repeater gets senout to other port
Data gets passed along by a repeater to all other LANsegments of a network regardless of whether it needs to go there or not
This is just an educated guest but i think ethernet is called ethernet as:
In the late 19th century, luminiferous aether or ether, meaning light-bearing aether, was the term used to describe a medium for the propagation of light.[1]
(Due to the negative outcome of aether-drift experiments like the Michelson-Morley experiment, the aether as a mechanical medium having a state of motion, is not used anymore in modern physics, and is replaced by the theory of relativity and quantum theory.) (wikipedia)
and well a ethernet cable is used to send information in the form of light to a net of computers to produce a LAN etc so this is why i think it derives form Einsteins hypothesis.

In wired systems the transmitter-receiver pair is commonly referred to as a modem (modulator/demodulator); in wireless systems the terms transmitter and receiver continue to be used; and for fiber-optic cable systems the terms electrical-to-optical (E/O) and optical-to-electrical (O/E) interfaces are used to describe the transmitter-receiver pair
Why do you need computer networks?
you dont "need" a computer network. you also dont "need" the internet (which is basically a giant network)
Protocols in what layer coordinate and maintain communications between two nodes on the network?
Session Layer
A client server is better because you can set limitations such as blocking access to system files, and etc. Also it is easier to make internet filters for that one type of client they are set as so they are not doing anything they shouldn't be doing.
What can be enabled on a wireless network by turning on WEP or WPA?
WEP, WPA, WPA2, etc, are just encryption protocols.
WEP is by far the easiest for hackers to break literally in seconds to minutes. WPA is much better but is slowly getting easier to crack, WPA2 Personal is the best you can use now for the consumer. Some fairly older wireless devices may not support WPA2 tho. At the very least use WPA with a long random password if you can't use WPA2.
What are the advantages of using an ISA server?
The advantages of using an internet security and accelerator or ISA server is that your e-mail and network will be protected. It ensures authentication measures are taken.
How many network cards are between 0020afcd5223 through 0020afcd522e?
Using Hexadecimal system from 0123456789ABCDEF we can see that the last digit on both cards are changed. So there would be 10 cards in between the 2 initial ones and 12 including them.
Why is it important to isolate the power source before you begin installing new hardware?
For one thing you are protecting the hardware form static electricity. Then there is the shocking reminder computers do give to those who do not treat electricity with respect

What does IP address 150.0.0.0 resembles?
I would say it resembles a network ID because no individual computer can have an IP address that ends with 0 because that's reserved for the...network ID.
What computer network layout does an education institute use?
It depends, but most grammar level schools will use a LAN, bigger education institutes use WAN to communicate and exchange data over long distances e.g. campuses with multiple buildings.
LAN usually refers to a network within the same building.
Formula to get logical to physical address in paging?
(frame no * page size) + offset value = physical add
where
frame value is the value present in the corresponding page number
offset value is the last n bits of the logical address
page no is the first m-n bits of logical address
2^m is the logical address
2^n is the page size
How do you block a website with Beetel router?
