Windows Vista, the operating system is almost identical to windows XP but has better graphics tapilan

Windows 7, is the development of a system for the previous operation that is supported by drivers making it easier for the installation.

Windows 8 operating system, is the latest exodus from windows by presenting a very beautiful interface and better.

Of the many operating systems that microsoft made a lot of advantages and drawbacks, the following are the advantages of the windows operating system:

1. A familiar GUI so users are more comfortable being in front of the monitor screen 
2. The support device of a better driver
3. Many Office applications that are compatible with windows
4. Easy to use, because the user is already familiar with the look of windows

How to Find and replace a Speedy Modem IP Address

To find out the IP Address of the modem Speedy is really quite easy. IP Addressmodem must you know, this is useful if you want to do further configuration of your modem. Or if you want to do the settings on the router. The IP address of the modem is also useful if you want to get into the admin panel of the modem. If you forgot your Speedy modem IP address, you can reset the modem and making rearrangement. Here I exemplifies the modem that I wear is a Speedy modem TP-Link TDW8151N.

To be able to know the IP address of the modem first, make sure your computer's IP is already set to default, sometimes people forget to change the computer's IP to the default so that it can't get into the admin panel of the modem. Here I'm using Windows 7, for Windows, others can customize it, here's how:

1. Click on the network icon at the bottom right of your computer and then click Open Network and Sharing center

2. Click on Local Area Connection

3. In the Local Area Connection Status, click on Properties

4. Double-click on Internet Protocol Version 4 (TCP/IPv4)

5. on the General tab, select Obtain an IP address automatically and Obtain DNS server address automatically, then OK and close

Get here your computer's IP address is set to default. Well now to find out the IP address of your modem for Speedy way is as follows.

1. turn on the modem and connect it with your computer, no doubt using a LAN cable

2. run Command Prompt (open CMD)

3. Type in CMD ipconfig and press enter

4. Note on Default Gateaway, this IP address is the address of your modem

From here I can now tell my Speedy modem IP address is 192.168.1.1

By knowing the IP address of the modem you can now login to the admin panelmodem and then you can change the default modem IP matches what you want, how is

1. open the browser Firefox, Chrome or IE

2. Type in the browser address bar to your modem's IP address above, e.g. his IP 192.168.1.1 and press enter

3. the login window will appear to enter the admin username and password, the default username and password speedy modem TP-Link TD-W8151N is admin

4. you will get into the dashboard modem, to find out or change the IP address of the modem, go to the Interface Setup > > LAN

5. IP address 192.168.1.1 you can change according to taste, e.g. 192.168.2.1 192.168.3.1 or

6. then click SAVE, done. Usually after click SAVE then the browser loading process will continue to be, don't wait until the loading is complete, after click SAVE then otomatisIP address your modem has changed.

Of note, change the IP address of the modem it is not carelessly done. If you Speedy modem users without routers should let the modem IP address by default. Replacement IP address is usually done for people who combine a modem with router, e.g. at the cybercafe. Change IP addressmodem is usually done if someone bought a new modem, that his IP address not the same as the old modem, rather than changing the default router is better simply change the IP address of the modem to the router's public IP matched with.

So the tutorial how to find and replace the IP address of the modem Speedy, particularly Speedy modem TP-Link TD-W8151N. We wish to add a bit of science about Speedy modem.

How to Enable Telnet

Telnet is a Protocol and application that can be used to control remote computers in a Local network or over the Internet. Although including a protocol that was very old and less secure, however telnet remains the still widely used to this day. Not the same as Remote Desktop using graphics as it looks, Telnet has only text mode display, and you must use the CLI (command line interface) in the implementation.

In this tutorial we will discuss how to enable telnet in Windows 8, so that our computers can be remote (control) over the network.
The first thing you should do before you enable the telnet service in Windows 8 is ensure that Telnet Server is already installed on the computer that you want to remote (kompter target) and make sure you have installed the Telnet Client on the computer that will perform remote (client computer).

In this article we will assume the target computer (which you wish the remote) has IP Address 10.2.2.2 and computers who want meremote is 10.1.1.1, make sure that you have menyetting IP Address correctly.

To install the Telnet Client and Telnet Server, you can perform through the Control Panel Program > > Program and Feature. And then click Turn Windows features on or off, and then tick check on Telnet Clientatau Telnet Server as in the picture. Then click OK to perform the installation. (sometimes have to restart the computer)

After the installation is complete, move the following things you need to do is run the telnet service on the target computer, from the Run dialog box (Windows + R), type services.msc, who will open the Services MMC.

Then in Service MMC, locate the telnet service, double-click the service, and then change the startup type from Automatic to be Disable, click Apply, and then click Start, and then click OK. Make sure the result as in the picture below.

The next step is to determine which User on the target computer are allowed to Login via Telnet service. For that you need to log in to the Local User and Group, here's how from the Run dialog box (Windows + R) type LUSRMGR. msc, to open the Local Users and Groups MMC.

On Local and Group MMC, click Groups, and then double-click the Telnet Clients group to membukaTelnet Clients Properties, and then click Add, as shown in the image below.

Then type the name of the user who you want to give access to telnet (in Figure assumed at the target computer is the name of a user named admin), and then click Check Names to verify that you're not incorrect typing user name, and then click OK, and click OK again to close the Telnet Clients Properties.

Up here you have finished the configuration on the target computer (the computer that you want to remote). Next to do the testing you could try it from another computer (client computer) and enter the command telnet < target ip address > in command prompt. As in the picture below (assuming the target computer's IP address 10.2.2.2)

So the tutorial how to enable the Telnet service in Windows 8. Good luck and happy learning ... you!!

Division Of IP Address Classes

For this time I will discuss about the IP address class divisions. The basic consideration of the Division of IP address into classes is to simplify the distribution of IP address registration

Version 4 IP address consists of 4 octets, and the value 1 octet is 255. Since there are 4 octet then the number of available IP address is 255 x 255 x 255 x 255. The IP address should be doled out as much as throughout the internet network users around the world. To ease the process of Division, the IP address should be grouped in classes.

IP address are grouped in five classes, namely class A, B, C, D, and e. the difference is in the size and number of. Class A network IP address. Class B IP address used for large and medium network. Class C IP address for the network Division of a lot, but each network has a few members. IP address Classes D and E are also defined, but is not used in normal usage, a class D multicast network intended for, and E for experimental.

Division of IP address classes are based on two things, namely the Network ID and Host ID of an IP address Any IP address is always a partner network ID (Network Id) and the Host ID (such as a host in a network). Each computer/router on a network host his ID must be unique (must be different with other PC/labtop yg).

Division Of IP Address Classes

Class A

Format 0nnnnnnn hhhhhhhh.. hhhhhhhh hhhhhhhh. (n = Net ID, h = Host ID)

The first bit is 0

Net ID length 8 bits (1 octet)

The length of the Host ID 24 bits (3 octets)

The first octets 0-127

The IP address range 1. xxx.xxx. xxx. up to 126. xxx.xxx. xxx (0 and 127 are reserved)

Network number 126

Number of IP address 16.777.214

Class A IP network for a bit with the host very much. How to read the class A IP address for example 113.46.5.6 is the Network ID Host ID: 113, = 46.5.6

Class B

The format nnnnnnnn hhhhhhhh.. 10nnnnnn. hhhhhhhh (n = Net ID, h = Host ID)
2 the first 10 bits
Net ID length 16 bits (2 octets)
Host ID length 16 bits (2 octets)
The first octets 128-191
The IP address range 128.0.0. xxx.xxx 191.255 until xxx.
The number of Network 16.384
Number of IP address 65.534

Commonly used for medium and large networks. the first two bits are always set to 10. the next 16 bits, class B IP network can accommodate approximately 65000 host.

The format nnnnnnnn hhhhhhhh.. 10nnnnnn. hhhhhhhh (n = Net ID, h = Host ID)
2 the first 10 bits
Net ID length 16 bits (2 octets)
Host ID length 16 bits (2 octets)
The first octets 128-191
The IP address range 128.0.0. xxx.xxx 191.255 until xxx.
The number of Network 16.384
The number of 65.534 class C IP address

The format nnnnnnnn nnnnnnnn.. 110nnnnn. hhhhhhhh (n = Net ID, h = Host ID)
the first 3 bits are 110
The length of the Net ID 24 bits (3 octets)
Host ID length 8 bits (1 octet)
The first octet of 192-223
The IP address range of 192.0.0 to 255.255.255. xxx. xxx
The number of Network 2.097.152
Number of IP address 254

The host ID is 8 bits terakhi, with class C IP, can be formed about 2 million network each have 256 IP address the first Three bit class C IP address always contains 111 21 bits with the next. The host ID is the last 8 bits.


Class D

Format 1110mmmm. mmmmmmmm. mmmmmmmm. mmmmmmmm
4 the first Bits 1110
28-bit multicast bit
The initials of the 224-247 bytes
Description of the Class D multicast address space is

This class is used for Multicasting purposes. 1110 first bit, 4 bit-the next bit is set according to the purposes of multicast group that uses this IP address. Unknown network multicasting in a bit and host bits.


Class E

Format 1111rrr. rrrrrrrr. rrrrrrrr. rrrrrrrr
the first 4 bit 1111
Spare bit 28 bit
The initials 248-255 bytes
Description of the Class E address space that is reserved for experimental purposes


Commonly used for medium and large networks. the first two bits are always set to 10. the next 16 bits, class B IP network can accommodate approximately 65000 host.

How to limit the time main labtop

Sometimes, on a PC/labtop we have more than one user account, a user for our use, and another for the user used another person in our family. It is also often used in small offices that are not using the Domain Controller, in which a computer/labtop to sharing to some employees.

In Windows 8, there are features of Family Safety. This feature allows us to provide restricted access on another user's computer/labtop us, an example is to restrict the time a user login. Actually in Windows 7, there is such a feature, that is, Parental Control, but in Windows 8, it was renamed to Family Safety, of course with some excess which is not owned by
Parental Control.

We can access Family Safety from your Control Panel, or by pressing the Windows key + W (the windows key and the letter w on the keyboard), and then type settings result in family, Family Safety, click as shown below;

Family Safety Control Panel can be seen in the example image below;

In the picture above there are three user accounts, namely JamalNst (administrator), brutal (standard user) and rafiqa (administrator). Further information about the user account you can read in the create user accounts and change the account type.

We will try to enable Family Safety on user puspita (standard user), for that you need to log in using another user account (administrator). Click on the user account that you want to set, for example in the image above we click user puspita.

Then you need to enable Family Safety on the brutal user, click On, enforce the curent settings. Then click Time limits. You can see in the image below.

Here there are two options, namely the Set time allowance and Set curfew. You can make settings on one or both of these options.

On the first Time allowance options you can set how long a user can use a maximum of brutal killings in accessing the computer/labtop, clicking on the caret for more detail.

Maybe you want to restrict your child should only be using a labtop computer/4.5 hours a day. In the example picture below I restrict users puspita could only use computers 4 hours 30 minutes on Monday to Friday, but gave him the freedom to access the computer on Saturday and Sunday.

In the second option IE the Curfew, we could limit the hours, how many other people can access your computer. For example, in a small office you do not allow employees to access the computer outside of work hours.
In the example image below, I will limit the user shouldn't be using computers puspita from 8 am to 8 pm (08.00 to 20.00). You can simply click on the box and highlight the Curfew.
The blue color indicates Blocked (no access to computers) and white marks Allowed (allowed to access the computers).

To do the test you can try to login using the user puspita.

In addition to the limitation of time, Family Safety can also be used for restrictions on websites, games, and application. We will discuss that on another occasion.

Congratulations and good luck with learning ... you!!
