understanding and internet history

Internet comes from the Latin inter, meaning "between". The word Internet can be defined between or connective tissue. Internet link the various networks that are not mutually dependent on each other so that they can communicate. What system is used on each network is not a problem, whether DOS or LINUX system.

While local jaringa usually consists of a type of computer (eg DOS or LINUX) INTERNET overcome differences in a variety of operating systems by using the "language "of the same by all networks in pengirman data. basically this is what causes the large dimensions of INTERNET.

Thus, the definition of the Internet is a network of inter-network by creating the possibility of a worldwide network without depending on the type of computer.

ARPANet

In 1969 ARPA a part of the ministry of defense the United States began a project, which on one hand creating communication channels that can not be destroyed and on the other hand facilitate the cooperation between research bodies across the country, as well as the arms industry. Is formed ARPANet.

INTERNET Project

develop the results achieved by ARPANet, for this new communication media can also be used by various computer systems are connected. Then vendors meramikan computer network traffic for various needs thus create INTERNET.

HITACHI HT545050 KTA (500 GB.)

HARDDISK 2.5-inch hard drive is the drive launched by the factory with the name Hitachi Hitachi 500GB HTS545050KTA. This hard drive is included in Hitachi Travelstar series with a capacity of 500 GB. A capacity large enough to drive this small. Once formatted, this hard drive has a capacity of 465.8 GB, still quite large. The most notable special feature is Bulk Data Encryption, which serves to secure the existing data in the hard disk.

The resulting overall performance is pretty good. In some benchmark tests, this hard drive to obtain satisfactory results. But there are some tests that get less good results, for example accesa time that requires a long time and a significant increase in temperature at full time, up to 39 celcius labeling.

With large capacity and compact size, this hard drive should be considered for those of you who are looking for an additional hard drive.

UNDERSTANDING THE COMPUTER NETWORK

By definition, is a computer network is an interconnected set of kompter autonomous. In popular language that can be explained that the computer network is a collection of several computers that are connected to each other through the media intermediary. Media intermediaries can be either wired media or wireless media. The information in the form of data will flow from one computer to another or from one computer to another device, so that each computer connected can exchange data or different hardware.

For ease of understanding the network of computers, the experts then divide the computer network based on several classifications, including :

1. based on the area or scale

2. based on conductive media

3. by function

But there is also a classified computer network into four namely:

1. based on the area or scale

2. based on conductive media

3. by function

4. based access control methods

By Area computer network is divided into four namely :

1. LAN (Local Area Network): is a local network which is made in a closed area.

2. MAN (Metropolitan Area Network): using the same method with a LAN but a wider coverage area.

3. WAN (Wide Area Network): scope broader than the MAN.

4. Internet: is the interconnection of computer networks in the world.

Based on Media Conductor

1. Wire Network: a computer network using cable as a medium of Conductor.

2. Wireless Network: wireless network that uses radio waves Conductor media or infrared light.

Based Function

1. Client Server is a computer network in which one (may be more), the computer functioned as a server or host for another computer.

2. Peer to peer: a network of computers where each computer can be a server while the client.
