Computer Networking

Network+ is officially a "vendor neutral" certification. However, a candidate for the designation is expected to have knowledge about Windows Server 2003 and Unix/Linux servers.

Reverse name resolution

Advantages of network are:

it help the users to communicate to each others

it facilate the communications because people can communicate efficiently and easily via e-mail instant messaging and chatroom.

it has no need pf charging the buttery.

it is more difficult to be theft than a laptop.

it is cheaper than a laptop.

It uses something called a checksum to verify datagram integrity

TCP Communications
TCP is a connection-oriented protocol, which means that before two systems
can exchange application layer data, they must first establish a connection. This
connection ensures that both computers are present, operating properly, and
ready to receive data. The systems also exchange information about their capabilities,
which determines how subsequent communications will proceed. The TCP
connection remains active during the entire exchange of data, after which the
systems close it in an orderly manner.
In most cases a TCP connection exists for the duration of a single file transmission.
For example, when a Web browser connects to a server on the Internet, it
first establishes a connection with the server, then it transmits a Hypertext Transfer
Protocol (HTTP) request message specifying the file it wants to download, and
finally it receives the file from the server. After the file is transferred, the systems
terminate the connection. As the browser processes the downloaded file, it might
detect links to graphic images, audio clips, or other files needed to display the
Web page. The browser then establishes a separate connection to the server for each
of the linked files, retrieves them, and displays them as part of the downloaded page.
Thus, downloading a single Web page might require the browser to create many separate
TCP connections to the server to download the individual files.

the Internet was never something else the government and big businesses had it to check prises for better profit even in the mid 80's it just wasn't out for the public use till about 1992

Wirelessly.

http needs a reliable mechanism to provide connectivity between the Host i.e. the web browser and the Server i.e the web server.

Now TCP is the transport layer protocol that provides it reliable communication with three-way handshake mechanism it uses to connect between a client and a server. We also have UDP at transport layer but it is not reliable way of communicating.

So http uses TCP at transport layer of OSI Model.

In the OSI reference model, that would be layer 3 (network).

In computer networks, failover support is a method for protecting availability of a computer resource. For failover support to work, a component must have a redundant or alternate and there must be an ability to detect the failure of the primary component and switch to the alternate. As an example, a company web site may be hosted at one location but have an alternate hosted at a different location. If the primary site goes down, traffic directed to the primary site is redirected to the alternate site in a manner that is transparent to the outside user.

If your business has an IT section then that is first party. Third party servers are the IT equivilant of storage that you rent space on when you want to run your business

WAN = Wide Area Network

The internet could also be considered as being a WAN.

Structured cabling is used for telecommunications withing a building or campus. The reason it is called structured is because it is made up of many different subsystems.

you can't. There's no way to know from an IP address wha the subnet mask is.

However, there are some likely guesses. Since 195.0.8.0 ends with a zero, the subnet is probably a 24-bit mask: 255.255.255.0

But it doesnt have to be. The network administrator knows for sure.

Unfortunately not. RJ45 Straight cables, are for use with hubs / switches and routers.

If you want to network 2 pc's together without a hub, you need a cross over RJ45 cable.

Hope this helps

Modbus is an industrial communications protocol. If you are referring to the word Modbus, I have not read it but suppose it comes from (MOD)icon (BUS).
