Local Area Network

The default subnet mask for this address - a class A address - is 255.0.0.0 (same as /8).

Devices on a linear bus network are connected to each other via a wire, usually through a T-connector device. In effect, the devices are "daisy chained" together without any other device connecting them.

A simple explanation is that the cloud or cloud computing means storing or accessing data and programs over the Internet instead of your computer's hard drive. The Cloud just means Internet. The purpose of the Cloud is to share. Cloud computing is a concept, more than a technology - which is to say it is a new way of approaching the use of existing technology. Rather than owning the software involved in that technology yourself (which, as a business user, can often require large expenditures in terms of annual licenses and the upfront costs of the packages themselves), you lease it from cloud computing service providers. That is, the service providers that run cloud computing stations for your industry own all the latest software and tools, and you pay them a monthly or as you go fee for their use. The advantages of this kind of scheme are immediately obvious. You might not be able to afford the latest and best versions of all the commonly used software in your industry. You probably can't justify the expense of a piece of software that is only used very occasionally in your industry. But when your cloud computing service providers own it all already and you just have to pay to hire it - well, then you can afford to use the best of everything whenever you need it.

The common topology in use today is the STAR. Hubs or switches are used to connect computers together like a "HUB". Switches are faster and better than a hub. Hubs, switches or servers are connected between each other by a "uplink" port that is specifically used to connect these devices together. There are 4,12,24,48,or 96 port hubs that can be purchased. Two hubs connected together with 96 ports would be able to serve 192 computers together. The possibilities are endless.

Yes, Ethernet is very common on LANs and is a baseband transmission type.

Only 1 packet at a time can use the network resources at a time; the other packets will cause a collision in an Ethernet network. For Token Ring, only 1 packet at a time is on the network (via the token).

In short, yes you can, but some devices require more power than others to function properly so you may see a drop in performance or range but yes, the device SHOULD function to a reasonable extent using a usb hub.

no, A LAN is a network between a small amount of computers through a router , hub or switch

Each component in a network connected by wires is called a terminal. Components in a network that are not connected by wires, such as in a shared Wi-Fi connection are also called terminals.

Without a default gateway you will not be able to route packets out of your LAN; in other words, you will not have Internet access, or access to any other network in the enterprise.

Not all systems use the same amount of bytes for a ping packet, although typically a ping packet is small. Windows uses 32 data bytes, some Linux systems use 56, and other Unix systems vary widely.

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)

No it's not illegal, but is is not allowed and you can get into serious trouble for it.

Apart from the silly mathematical answer, 802.3 - 802.11 = 0.19, the key difference between IEEE standards 802.3 and 802.11 is that 802.3 governs wired Ethernet communications, while 802.11 governs wireless LAN communications.

You would need to reserve an IP address range of 1,000 IP's. If you're making a private home network, I would use 10.X.X.X or the 172.16.X.X private networks. Those would give you plenty of room for host addresses, and you could even subnet it if you wanted too.

Local apps are programs that are used by individual computers while network apps are used by several (like the internet).

Like a switch, a router places nodes that are connected to it in separate collision domains.

OSI was made by ISO (international standards organization) in 1970s while, DoD was used by only the US govt.'s Department of Defense thus DoD model. DoD was primitive and had problems with it and was not in too much detail, so when it was available to public market, the ISO revised it and add more details and layers. Due to that it made it more specified.

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.

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).

Cat5, Cat5e, Cat6, and Cat6e can be used, u can always use a better cable than required, but not the other way around

No - in order to use ARP it would have to send a broadcast for information with a return address of itself. Since it doesn't have an IP address it cannot do that. Furthermore, without an IP address it couldn't participate on the network.
