Speed Internet Access Technics

When you are browsing or opening a website on the internet either from home or from Internet cafes, you may complain to the slow access to display the website. Though the internet access in Indonesia is still counted expensive now. Actually there are easy ways to improve the speed of your dorm access without having to pay more expensive. Some of them are with our set its browser, use OpenDNS, and use Google Web Accelerator.

To apply the tricks are very easy. The first mode is set its browser can be done by the users of Internet Explorer and Mozilla Firefox. Internet Explorer users click the menu [Tools] [Internet Options], click the tab [General]. In option "Temperory Internet files", click [Settings] and his slider Slide. It was to create a cache (temporary storage location) for your web open, otherwise provided approximately 5% of Hard disk.


For users of Mozilla Firefox you can type "about: config" in address bar. After that, change "network.http.pipelining" and "network.http.proxy pipelining" to "true", and the contents "network.http.pipelining.maxrequests" between 30 -100 (the greater the faster). The last right-click anywhere and select New -> Integer, write "nglayout.initialpaint.delay" then fill in with 0.

For the second trick, you must first register at http://www.openDNS.com. Then go to Control Panel from the Start menu, select Network Connections and select your connection and click properties. On the Internet you can select the protocol TCP / IP and click properties. Enter 208.67.222.222 and 208.67.220.220 in the DNS option and restart your computer.

After doing two tips above you'll now get faster access speed. For those still not satisfied with the access speed can now use a trick to three of Google's Web Accelerator. Google Web Accelerator is specifically designed to speed up your internet access, especially those of you who use a broadband connection (broadband) such as Cable and DSL. For those of you who use other connections such as Dial-up (Telkomnet Instant or Speedy) and satellite or wave, Google Web Accelerator can speed up access.

To use Google Web Accelerator you must meet criteria such as your Operating System must be Windows XP or Windows 2000 and your browser must be Internet Explorer 5.5 + or Mozilla Firefox 1.0 +. If for any other browser actually can, but you have to configure the proxy settings of your browser by adding 127.0.0.1:9100 on HTTP. After you do the installation, Google Web Accelerator will display a small icon on the browser and the icon tray at the lower corner of the computer screen. You can download the Google Web Accelerator in http://webaccelerator.google.com

Type Of Cabling

There are several types of wiring used and can be used for deploying Windows, namely:
1. Thin Ethernet (thinnet)
Thin Ethernet or thinnet has advantages in terms of cost is relatively cheaper compared with other types of cabling and the installation of components easier. Cable length anorectic coaxial/RG-58 between 0.5 - 185 m and a maximum of 30 computers connected.
2. Thick Ethernet (Thicknet)
With an Ethernet or thicknet fat, the number of computers that can be connected in a network would be more distance between your computer and can be enlarged, but the cost of procurement is more expensive wiring and installation is relatively more difficult compared with thinnet. In Thicknet transceiver used to connect each computer with network systems and connectors used are type DIX connector. Maximum transceiver cable length 50 m, Thick Ethernet cable maximum length 500 m with maximum of 100 transceiver connected.
3. Twisted Pair Ethernet
Twisted Pair cable is divided into two types: shielded and unshielded. Shielded cable is the type that has a sheath wrapping while unshielded sheath has no wrapper. For this type of cable connection using RJ-11 or RJ-45. In coiled unify (10 BaseT) network, a computer arranged to form a star pattern. Every PC has a coiled cable centralized unify the HUB. Twisted unify generally more robust (reliable) than with anorectic line karenaHUB nonachievement rebuke accumulation ability and increase the transmission speed. While there are several grades, or categories of coiled cable pair. Category five is a sure fencing and has a high compatibility, and that fencing is recommended. Running well at 10Mbps and Fast Ethernet (100Mbps). Category 5 cable can be made straight-through or crossed. Straightforward finished cable used to connect the computer to the HUB. Decussate cable used to connect the HUB to HUB. Maximum Cable Length Twisted-Pair cable is 100 m.
4. Fiber Optic
Fiber Optic network using (FOR) are usually large companies, because prices and more difficult installation process. However, networks that use FOR in terms of reliability and speed are not in doubt. Accumulation with a transmission speed of more than 100Mbps FO media and free of environmental influence.
TCP / IP protocol
Because an important role in the Windows operating system and also because prescript protocol is a protocol options (default) from Windows. Protocol Transport layer protocols are in help OSI (Open Systems Interconnection), while the IP is in fashion OSI Network layer
IP Address
Come is the IP address provided on computer networks and network equipment that uses TCP / IP. IP come taste consists of 32 binary digits that can be written as four decimal digit groups separated by a dot, such as 192.168.0.1.
Examples of IP come:
Network ID Host ID
192 168 0 1
IP come in two parts namely meshwork ID and patron ID, where the meshwork ID to determine the network address of the computer, while the patron patron ID to determine the address (computers, routers, switches). IP therefore come to give the full address of a patron and patron network address where it is located.
IP Address classes
For ease of use, depending on the needs of users, IP come is divided into three classes as shown in table 1.2.
Class IP Address:
Class Network ID Host ID Default Subnet Mask
A xxx.0.0.1 xxx.255.255.254 255.0.0.0
B xxx.xxx.0.1 xxx.xxx.255.254 255.255.0.0
C xxx.xxx.xxx.1 xxx.xxx.xxx.254 255.255.255.0
IP come is given to class A network with a very large number of patrons. IP Range 1.xxx.xxx.xxx. - 126.xxx.xxx.xxx, there were 16,777,214 (16 million) come to each class of IP A. IP come is given to class A network with a very large number of patrons. In the IP addresskelas A meshwork ID is eight first taste, while the patron ID is 24 next taste.
Thus, how to read the IP come of class A, for example 113.46.5.6 is:
Network ID = 113
Host ID = 46.5.6
So that means the IP come on patron numbers meshwork 46.5.6 on 113 numbers.
Class B IP come is usually allocated for medium and large sized networks. In class B IP come, meshwork ID was 16 the first taste, while the patron ID is 16 next taste. Thus, how to read a class B IP come, for example 132.92.121.1
Network ID = 132.92
Host ID = 121.1
So come on top of IP means that the patron numbers on the meshwork 121.1 132.92 number. length
16-bit host ID, IP meshwork come with class B can accommodate about 65 000 hosts. IP Range
128.0.xxx.xxx - 191.155.xxx.xxx
Class C IP come originally used for small networks (LANs). Host ID is 8 bits
last. With this configuration, can be formed about 2 million with each of the meshwork
network has 256 IP addresses. IP Range 192.0.0.xxx - 223.255.255.x.
IP Allocation come basically is the process of selecting meshwork Id and patron ID is right for a network. Whether or not this configuration is appropriate depends on the goals to be achieved, which allocates IP come as efficiently as possible.

LAN

TCP / IP (Transmission Control Protocol / Internet Protocol) is a group communication protocol governing the accumulation computers on the Internet. The computers are connected to the internet to communicate with TCP / IP protocol, because it uses the same language differences in the type of computer and operating system is not a problem. PC computer with Windows operating systems can communicate with a Macintosh computer or with a Sun SPARC running Solaris. So, if a computer using a protocol prescript and connected directly to the Internet, the computer can connect with computers in the world where paronomasia which is also connected to the internet.
The characteristics of computer networks:
1. share hardware (hardware)
2. sharing software (software)
3. sharing of communication channels (Internet)
4. easily share accumulation
5. facilitate communication between network users
Local Area Network (LAN) is the number of computers linked together in one particular area that is not so broad, as in one office or building. Broadly speaking there are two types of networks or LANs, namely Peer to Peer network and Client-Server networks.

In Person to peer network, every computer connected to the network can act either as a workstation or server. While in Client-Server networks, only one yangbertugas computer as a server and other computers acting as workstations.
Between these two types of networks each have advantages and disadvantages, in which each would be explained.
LAN is composed of several basic elements that include components and software elements, namely
1. Physical Component
Personal Computer (PC), Network Interface Card (NIC), cable, network topologies.
2. Component Software
Network Operating Systems, Network Adapter Drivers, Network Protocols.
Personal Computer (PC)
Individualized type of computers used in the network will greatly determine the performance of the network. Computers with high performance will be able to send and access the fast accumulation in tissue. In the client-server type network, a computer that functioned as the computer is absolutely necessary to have a higher performance compared to the other computers as his workstation, because the computer would be on duty to provide facilities and manage the network operational.
Network Interface Card (NIC)
Based on the type of bus, there are several types of meshwork bill Programme (nic) or meshwork cards, namely ISA and PCI.
We have kind of meshwork bill that is widely used, namely PCI
Ethernet

In a network with access prescript CSMA / CD or Carrier Sense Multiple Access with Collision Detection, a convexity (A) that will send checks the first condition of accumulation of data points. If there is no flow of data / blank it will send its data convexity and convexity when the other (B) that are currently using accumulation point then the convexity (A) will wait and try to check back. In prescript access is possible at any moment occurred several convexity transmit data simultaneously impinging or causing a collision. In this condition, these nodes will be void send accumulation and will try it again when the line is not busy

Setting Virtual host for XAMPP

In the afternoon I will be comfortable enough to discuss a bit about virtual hosts and how to set vhost (virtual host) in the XAMPP web server. okay .. before we do the setting vhostnya we should first know the concept and understanding of the virtual host .. is a trivial virtual host is to make a few servers in a server .. which of course with a domain that berbeda2 .. eg-teladan.com www.sma .. or www.tokoku.com and so forth .. This vhost very helpful in the management of the local server, because we can freely create at will our domain but not with the same record with a domain that is already on the internet if the server is connected to the internet ..

we just discussed how virtual settings .. hostnya Here the web server I use is XAMPP .. many types of web servers available, please you use your liking ... there are some simple steps you need to do ..

The first step is that we first define the server name (domain) that we will use. files we have to change are in C: \ windows \ system32 \ drivers \ etc> hosts the following code should be changed / added

# For example:

#

# # Source server 102.54.94.97 rhino.acme.com

# 38.25.63.10 x.acme.com # x client host

127.0.0.1 localhost

127.0.0.1 sma1jogja.com

192.168.10.1 www.webku.com

the top of this you can add the domain name you'll use, also include IPnya address .. if you use a static IP, then it can be written as well.

The next step you need to modify the httpd.conf file located in C: \ xampp \ apache \ conf open the above files using Notepad or WordPad .. then locate the directory and change its configuration to be as follows:



Options Indexes FollowSymLinks Includes ExecCGI

AllowOverride All

Order allow, deny

Allow from all



If you've finished editing do not forget to save back the file.

okay .. Puspa now in the editing of the configuration steps are added to configuration in httpd-vhost.conf file located in C: \ xampp \ apache \ conf \ extra. Open the file with Notepad or WordPad and then tambai file with the following code:



DocumentRoot C: / www/sma1jogja.com # This is a directory rootnya ..

ServerName sma1jogja.com this # domain that has been made earlier





DocumentRoot C: / xampp / htdocs

ServerName localhost



okay dah .. konigurasi finally completed all the editing is not finished yet ... nka next step is to create a root directory. It serves as a place of our web files. The trick is to create a folder in C: \ with the name of the www and then enter a web that has been your files into folders for TSB. Do not forget to name the folders therein shall be equal to the root directory that you've defined.

If all the above configuration is complete, run the restart atao XAMPPnya XAMMP if that was the road.

Testing with the browser, and in the address bar enter the domain where we have made
