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.

Can users share a public ip address?
Yes, this is done routinely, in part because of the scarcity of public IP (version 4) addresses.
To achieve this, the users within a network use private IP addresses, in one of the ranges recommended by RFC 1918 - for example, any address that has "10" in the first byte.
A NAT device will do the address translation on the border between the internal and the external network. The result is that equipment on the outside of our company's network will only see the single public IP address.

What happens to frame when corrupted on bus topology?
When a frame is corrupted on a bus topology, it never reaches its destination. The bus topology has a method called ACK. ACK for acknowledgment sent on the back of each request. So if the destined computer gets the packet it sends back an acknowledgment signal. Therefore it the first computer sent a corrupted frame if the time-out occurs meaning it did not receive an ACK back then the ARQ(automatic repeat request) is called and the original re-sends its message until it receives its ACK.
How do you connect your PC laptop to your att uverse box?
The router is wirelss so that is how I connected. There is also a plug for an Ethernet connection on the back you can use.
What is the primary motivation for the development of IPv6?
Q: What is the primary reason for development of IPv6?
A: expanded addressing capabilities
Domain networking is a network infrastructure/setup which is usually used within a business. It can span across one location or across many locations. Domain networking using Microsoft Windows Server allows the network to be configured with user accounts stored on one location (On Microsoft Networks it would be the Domain Controller).
Domain networks allow users to logon to any computer using one set of credentials. The users documents are automatically transmitted from the network servers to the users computers.
Domain networking allows network administrators to manage computers and users from one location making it the best option for medium -> large sized organisations.
Compared to Domain networking, workgroup networks only use local user accounts and this solution would be better for home users and (very small businesses e.g. 1 man band businesses)
You already have a BT Vision Box and all you need is the account how do you get one?
Contact BT and the people there will talk you through what an account is, why you need an account, and the range of options you have.
What layer correct errors in osi model?
The Transport Layer and Data Layer can provide error detection and correction at the different levels of data transmission. Network layer can also correct errors if it detects them.
What does the network specialist Ciena specialize in?
The network specialist Ciena is a business network optimization company. They specialize in optical, Ethernet, and network automation to help your business reach its highest potential.
Major limitations of twisted pair cable?
The length of the cable is typically limited to 100 meters. The cable should not pass too close to sources of electromagnetic interferences (for example, motors). This type of cable has a limited bandwidth; typically much less than that of fiber optic cables. The bandwidth of twisted pair cables is typically 100 Mbps or 1 Gbps.
Ethernet hardware addresses are 48 bits, expressed as 12 hexadecimal
digits (0-9, plus A-F, capitalized). These 12 hex digits consist of
the first/left 6 digits (which should match the vendor of the Ethernet
interface) and the last/right 6 digits which specify the interface serial number for that interface vendor.
These high-order 3 octets (6 hex digits) are also known as the
Organizationally Unique Identifier or OUI.

What is true about local and network applications?
Local apps are programs that are used by individual computers while network apps are used by several (like the internet).
Utp straight color coding in switch to switch?
Switch to Switch with UTP requires a crossover cable. Straight-through cables generally will not work unless one of the switch ports is specifically designed to operate in DTE mode.
Which Linux distribution was recently acquired by the networking software company Novell?
SUSE. Although you have a really funny definition of "recent." The acquisition happened back in 2004.
Each computer on the Internet has a unique address called an IP address which stands for?
Internet Protocol I believe
How do you add a wired computer to a wireless network and be able to acces files over the network?
Connect a wireless network adaptor to the computer and configure the adaptor to connect to the wireless network that has the files you want to access.
Acceleration involves a change in what two components?
Acceleration refers to the change in velocity, which is a vector quantity, therefore, it means that acceleration can mean the change in speed or the direction of motion or both.

What is broad band remote access server?
The BRAS sits at the core of an ISP's network, and aggregates user sessions from the access network. It is at the BRAS that an ISP can inject policy management and IP Quality of Service (QoS).

Show a diagram or sketch of a cross-over cable in computer networking?
You can search for this diagram on an internet search engine, for example:

A signal which has frequencies from 0 to some band-limited value B.
OR
we can sy that baseband signal is a signal that can include frequencies that are very near zero, by comparison with its highest frequency
(e.g: a sound waveform can be considered as a baseband signal, whereas a radio signal or any other modulated signal is not baseband.)
What is the name for the computer network architecture standards developed by the IEEE for wireless?
Project 802
How do you get your weheartit account back if its deleted?
How can I make new account in weheartit ?!
Lost network key for my router?
The router will have an administration page, normally accessible with a browser, where you can reset the network key. I assume the key is for a wireless network, so you can access the router without a key by hooking up with cable.
If you have lost the password for the administration page as well, the router can be reset to default settings with a tiny button somewhere on the box. (The reset button is normally so small that you need a pen or similar to push it.)
To find the administration page and the default password, check the router documentation. You can normally find the details on internet when you have the router make and model, or you can contact support department of a computer store.
What is normal latency on cable modem in millisec What does TTL stand for on ping test?
Normal Latency of a cable modem is ideally between 5 and 40 ms. For a DSL modem this is normally 10 to 70ms. For a dial-up modem, this is normally anywhere from 100 to 220ms. For a cellular link, this can be from 200 to 600 ms. For a T1, this is normally 0 to 10 ms.
Whereas,
TTL or Time to Live refers to how many routers your packet can go through before it expires. Usually a packet finds its home in less than 32 hops, but 64-128 is a good default
