When does the Token Shop restock on Subeta?
I believe that i read somewhere that it only restocks when Keith wants it to.
So its totally random. Sorry!
Why do you need to ensure the cables are not twisted or plaited?
Because it would affect the Cross sectional area of the conductor therefore altering the resistance.
Which type of cabling is easiest to install?
In computer networking, the type of cabling that is easiest to install is coaxial cable. It is a light, inexpensive and flexible cable.
A B-to-B network is known as a extranet. It connects one business to another via a direct line. This allows a confidential network to be established for internal communication.
Where on computer is the proxy server address?
If using Internet Explorer: Select Tools, Internet Options, Connections, Lan Settings. If using another broswer, it can usually be found in that browser's network setup options.

Can you name 5 important ports of the world?
The most 5 important ports of the world: 1) HTTP 2) FTP 3) SMTP 4) TelNet 5) TCP
at the physical layer ,hub can support little in the way of sophisticated networking. hubs do not read any data passing through them and are not aware of there source and destination.
What are two primary responsibilities of the Ethernet MAC sublayer?
MAC provides physical addressing. The BIA (Burn In Address) which is stored in RAM when the computer boots up is added to each frame that is created as the source mac address.
But to answer your question, the MAC layer does the following: Data Encapsulation and Media Access Control.
Network Layer
Explain X25 protocols in the concept of network layer?
The X.25 protocol, adopted as a standard by the Consultative Committee for International Telegraph and Telephone (CCITT), is a commonly-used network protocol. The X.25 protocol allows computers on different public networks (such as CompuServe, Tymnet, or a TCP/IP network) to communicate through an intermediary computer at the network layer level. X.25's protocols correspond closely to the data-link …
How do you show the mac address table on an extreme Network Summit 300 24 switch?
Try show fdb.
if you want to show the ARP table use:
show iparp
Broad Area Network is also called WAN. A wide area network (WAN) is a telecommunications network, usually used for connecting computers, that spans a wide geographical area. WANs can by used to connect cities, states, or even countries. WANs are often used by larger corporations or organizations to facilitate the exchange of data, and in a wide variety of industries, corporations with facilities at multiple locations have embraced WANs. Increasingly, however, even small businesses are utilizing WANs as a way of increasing their communications capabilities. Although WANs serve a purpose similar to that of local area networks (LANs), WANs are structured and operated quite differently. The user of a WAN usually does not own the communications lines that connect the remote computer systems; instead, the user subscribes to a service through a telecommunications provider. Unlike LANs, WANs typically do not link individual computers, but rather are used to link LANs. WANs also transmit data at slower speeds than LANs. WANs are also structurally similar to metropolitan area networks (MANs), but provide communications links for distances greater than 50 http://www.answers.com/topic/kilometre. WANs have existed for decades, but new technologies, services, and applications have developed over the years to dramatically increase their http://www.answers.com/topic/efficacy for business. WANs were originally developed for digital leased-line services carrying only voice, rather than data. As such, they connected the private branch exchanges (PBXs) of remote offices of the same company. WANs are still used for voice services, but today they are used more frequently for data and image transmission (such as http://www.answers.com/topic/videoconferencing). These added applications have spurred significant growth in WAN usage, primarily because of the surge in LAN connections to the wider networks. How Wans Work WANs are either point-to-point, involving a direct connection between two sites, or operate across packet-switched networks, in which data is transmitted in packets over shared circuits. Point-to-point WAN service may involve either analog dial-up lines, in which a http://www.answers.com/topic/integrated-services-digital-network is used to connect the computer to the telephone line, or dedicated leased digital telephone lines, also known as "private lines." Analog lines, which may be either part of a public-switched telephone network or leased lines, are suitable for batch data transmissions, such as nonurgent order entry and point-of-sale transactions. Dedicated digital phone lines permit http://www.answers.com/topic/uninterrupted, secure data transmission at fixed costs. Point-to-point WAN service providers include both local telephone companies and long distance carriers. Packet-switched network services are typically chosen by organizations which have low volumes of data or numerous sites, for which multiple dedicated lines would be too expensive. Depending on the service, WANs can be used for almost any data sharing purpose for which LANs can be used. Slower transmission speeds, however, may make some applications less practical for WANs. The most basic uses of WANs are for electronic mail and file transfer, but WANs can also permit users at remote sites to access and enter data on a central site's database, such as instantaneously updating accounting records. New types of network-based software that facilitate productivity and production tracking, such as http://www.answers.com/topic/groupware and work-flow automation software, can also be used over WANs. Using groupware, workers at http://www.answers.com/topic/disperse locations can more easily collaborate on projects. WANs also give remote offices access to a central office's other data communications services, including the Internet.

What is specialized network interface card?
A specialized network interface card that performs additional functions in addition to creating the interface that goes in between cables. For example, WAN has these cards and it not only creates its own connections but also allows connection to a much larger network.
What is file signature verification?
A file verification signature is a program the helps when installing new software on a computer, system files and device driver files are sometimes overwritten By not signing or having incompatible versions, may cause system instability.
Not really. Depending on what your definition of "universal" is, there is a good chance you can install one in any given computer and network it, but there are (as with any devices) situations where it may not work in a given situation.
No. A network interface card could be connected through many different buses on a computer, such as PCI, ISA, PCI-E, PCI-X, or USB. If a computer does not have one of these interfaces, a card designed to fit that interface will not work.
No, although this is not really much of an issue, since routers and switches generally support multiple speeds. Just don't expect any improvements in your network if you upgrade your network card but negelect your router.
No. Wireless cards don't use any cabling at all! Still, this is again mostly a non-issue. The most common Ethernet cards and routers these days use a standard twisted-pair cable that is backwards-compatible with slower speeds (10BASE-T, 100BASE-TX, and 1000BASE-T). However, you may need to upgrade your cabling for faster devices, since they are more picky about cable length/ quality than the slower ones.
You'd have to either have megabucks or go out of your way to find them these days, but there are alternative networking cablings, such as fiber-optic (expensive), token ring (obsolete and slow), or coaxial (usually either expensive or ancient).
