Readers certainly already know not what it is a computer network? Yes, generally refers to a network of computers with two or more computers are connected and form a network with the goal to be able to cooperate, whether it's in terms of communication, data management, file sharing, and so on.

What the heck will we can from the system computer network? Computer network made of course not without purpose, benefits from computer networks, among others:
◾ Share resources
◾ Data exchange
◾ Communications
◾ Information access, and much more



Well, this time we will learn together is about the types of computer networks we encounter most frequently.


Based on the distance of the scope, the type of computer networks can be divided into:
Local Area Network (LAN)

A type of computer network that has the most narrow coverage than others. In general the type of LAN network we often find in various places which is certainly familiar to us, such as an Internet café, library, computer lab, school and so on.
Maetropolitan Area Network (MAN)
True to its name, this type of network range is a relatively broad area, for example between regions or between cities in the province. An example of this is the network can the occurrence in different branch of the communications bank centers in various cities.
Wide Area Network (WAN)

This type of network is a network that has the most extensive range. This network can connect the user network in various provinces. For example is the telephone network on the whole territory of Telkomsel Indonesia.
Internet
Yes, with this one surely we are familiar. The Internet is a network that allows the occurrence of communication between users around the world.
Types of computer network based on its function

Client-Server

is a network that uses a computer to be used as servers serving client computer, i.e. the party that meneripa services from the server computer.


Peer-to-Peer
Is a computer network that hosts him can be a server or a client simultaneously.

Types of computer networks based on topology

◾ Bus Topology
◾ Ring Topology
◾ Topology Tree
◾ Mesh Topology
◾ Linear Topology
Types of computer network based on the transmission media
 
◾ Wired Network (Wired Network)
◾ Wireless Network (Wireless Network)

How a fella? Already more familiar right about the type of network computer? A computer network that has been unraveling in the discourse above are the most common computer network we find in our daily lives. So thank you, and may be useful.

A BASIC INTRODUCTION TO COMPUTERS

Often hear the word "computer", perhaps readers already understand fundamentally about what is a computer. Computer is a device comprising several elekronik components that support each other. How to work a computer basically just take orders from the user and then process it and displays it in the form of visual and audio.

Modern times like this now of course we will not be easy to control the device with your computer. Almost all the activities that we do each day is always associated with a computer. Whether it's activity for students who are looking for subject matter with computers and the internet, or even for Office workers as a major mainstay for running the task.

The computer like a robot that is very easy to us control. The work of modern humans have been successfully implemented by either using the computer. Thus, it is of course when we are grateful for the presence of advanced technology such as computer so that all the activities that we ought to do can be properly processed by the computer.

Well, until here of course you already know not, about computers? Next movie let us know the one at a computer parts. Components or parts of the computer is divided into 2 parts, namely the internal components and external components.

We advance the external component language consisting of four components, namely CPU, Monitor, Mouse, Keyboard. The CPU is the central control computer that some components such as the processor, motherboard, hard disk, power supply and many more. The monitor, that is used to display data in visual form (pictures, video).

Then the mouse called a mouse, because its shape resembles a rat. This device serves to show the cursor in the screen of the monitor so that it can clearly if users want to operate a computer. Then next is the keyboard, which functions to include a specific command by pressing special keys.
Other ekternal components include: a functioning Printer to print the pages to paper media; DVD-Room function read disk CD/DVD; Modem serves to connect the devices with the internet. And many more external components of a computer, however the reviews felt quite as a basic introduction about computer.


Perhaps here the author lays out all the relevant information about the computer. Hopefully can provide benefits to you. Thank you

ALL KINDS OF COMPUTER MONITORS AND EXPLANATION

Computer monitor expanded rapidly from year to year. These developments certainly accompanied with the development of modern technology. The monitor itself is experiencing some of the evolution which then produce goods of high quality and modern technology.

In this paper, the author will analyze four different types of computer monitors and their explanation. Following his review:

Chatode Ray Tube (CRT)

The first type for a computer monitor is a CRT. This type of monitor is designed of vacuum tube as its screen media by using the cathode ray tube. People refer to it as a monitor screen that stands out because of the tube forward (convex). CRT monitor size is quite large so takes up a place. Typically, computers that are still standard (OS Windows XP down) use CRT type monitor screen. Now it has abandoned many of the computer manufacturers because of its size the less effective.

Liquid Cristal Display (LCD)
 
Unlike the CRT monitor screen, this time i.e. screen LCD monitor has used the technology a little further. Its shape is flat because it impressed using technology called flat panel display (monitor sailed flat). LCD monitor screen resolutions higher than CRT. However, the ukurang screen LCD monitor has a sleek shape and flattened. No wonder when many manufacturers use this as a type of monitor screen display monitor devices laptops, netbooks, and so on.


Light Emitting Diode (LED)
 
Next up is the screen monitor named LED or light emitting diode. LED display screens have a size and shape that are slimmer than the LCD. This type of monitor screen has been adopting LED backlight technology that more efficiently when issuing a light. Thus, energy power LED monitor screen is smaller so it will be more saving power consumption. But it is also not in spite of weaknesses, LED monitor screen dibanderol prices quite expensive.


Plasma
 
The technology used in the Plasma-screen monitor is much more modern than the previous 3. This monitor uses neon gas/xenon, placed between two layers of glass plates. On the electrified gas layer so that it will react with bring up the pixels. Of course, the quality of visualization of Plasma screens is highly seeded. However, for memperbagus quality, Plasma screen monitor adopted a joint technology between CRT and LCD.


That's a brief reviews about the types of computer monitors and their functions. Hopefully can provide clarity for You Dear reader.
