Difference Between Straight Through, Crossover, And Rollover Cables

Straight-through cables get their name from how they are made. Out of the 8 pins that exist on both ends of an Ethernet cable, each pin connects to the same pin on the opposite side. Review the diagram below for a visual example:

This kind of wiring diagram is part of the T-568A standard.

Straight-through cables are primarily used for connecting unlike devices.
    * 1. Connecting a router to a hub
    * 2. Connecting a computer to a swtich
    * 3. Connecting a LAN port to a switch, hub, or computer

The Purpose of Crossover Cables

Crossover cables have pairs of wires that crisscross. This allows for two devices to communicate at the same time. 

Switch the orange-white and green-white wires, and then the orange and green wires. This will enable like devices to communicate.

Use crossover cables to connect like devices.
    * 1. Connecting a computer to a router(exceptional)
    * 2. Connecting a computer to a computer
    * 3. Connecting a router to a router
    * 4. Connecting a switch to a switch
    * 5. Connecting a hub to a hub

The Purpose of Rollover Cables

Rollover cables essentially have one end of the cable wired exactly opposite from the other.  Rollover cables, also called Yost cables, usually connect a device to a router or switch’s console port. This allows a programmer to make a connection to the router or switch, and program it as needed.

Notice that each wire is simply “rolled over.” These types of cables are generally not used very much, so are usually colored differently from other types of cables.

The Console Cable

Console cable are mainly used to configure CISCO routers or switch using HyperTerminal

Don’t plug it into the Ethernet port!   Remember, it is a Serial Cable.

You need to connect it to the 9 PIN serial port on your PC  and the other end to a router at the console port(not Ethernet port).

Once connection is done you need to use your terminal emulator to communicate with the console port.

Enable virtual Wi-Fi on your PC

Windows 7 includes a little-known new feature called Virtual Wi-Fi, which effectively turns your PC or laptop into a software-based router.

What is Virtual Router?

Virtual Router is an open source software based router for PCs running Windows 7 and its freely available for users.

Through Virtual Router, users can share their internet connection with any Wi-Fi device (Laptop, Smart Phone, iPod Touch, Net book, wireless printer, etc.)

These devices connect to Virtual Router just like any other access point, and the connection is completely secured using WPA2 (the most secure wireless encryption.).

By using Virtual Router you can establish most secure wireless access point without any cost.

Features of Virtual Router Manager :

1.Added Installation Check for Windows 7 / 2008 R2 or later

2.Added ability to customize the icon displayed for a particular device / connected peer. To do this, either "double click" the connected peer, or "right click" and select "properties".http://www.blogger.com/img/blank.gif

3.Added Network Name (SSID) and Password Field Validation. SSID can not be longer than 32 characters, and Password must be at least 8 characters and no more than 64 characters.

4.Persist SSID and Password across executions so that the user doesn't have to type it in every time.

5.The First time Virtual Router Manager is run the Password/Passphrase field is blank. This is to encourage users to enter their own password instead of just using the "default" value in an effort to help increase the overall security. This way there is no "default" password for hackers to try connecting with.

Note : Virtual Wi-Fi can be done without using any software but this is the simplest and secure way to create an Virtual Wi-Fi Router

These 10 tips are simple things you can do to make your laptop run faster.

1.Start with a disk cleanup. There are several ways to access this, but one is to click on the Start Program>All Programs>Accessories>System Tools>Disk Cleanup. This will allow you to delete temporary Internet Files, Offline Files, the recycling bin, and other types of unnecessary files. 

2.Through the Control Panel, go to Internet Tools and delete cookies and history. This can take several minutes if it hasn’t been done in awhile.

3.Disk Defragment. You can access this the same way as a disk 

cleanup, but select disk defragmenter instead. Many programs allow you to schedule a time to do this application, as it can take several minutes or several hours depending on how much work is to be done. 

4.Malware or Spyware are big offenders of slowing down laptops. Installing and running an anti-malware or anti-virus program and running it regularly will often times make a tremendous difference. 

5.Check your power management by accessing the Control Panel. Select power management and then Maximum or Best Performance. If you use your battery pack rather than being plugged in it will drain quickly, but will give you optimal speed. 

6.Check the memory usage of your computer. You may need to add more random access memory (RAM) to store memory, rather than using disk space that is slower in all cases.

7.New computers that use Windows Vista/7/8 can be slowed down by excess animation. It is possible to turn it off by going to the Control Panel>System and Maintenance>Performance Information and Tools>Advanced Tools. Then select Adjust the Appearance and Performance of Windows. The Performance Options box will prompt, and if you select Custom, then uncheck Animate Windows when Maximizing and Minimizing. You can consider other options as well, but this definitely pep it up.

8.Use an external hard drive to store all music, photos and games. It can be unplugged and used with multiple computers, and will save valuable space.

9.Consider using registry software cleaner or repair program. There are many good ones out there such as ccleaner.com or registryfix.com. These will identify and repair problems within the registry.

10.From the Control Panel, go to Add or Remove programs. Remove programs that you know you are not using. This can be a daunting task, since some programs affect others, and therefore you may want to know what’s important before you remove it.

How Google can made your life easy.

All of us have been using Google since like forever. Most of us have been using it for just as a search engine ( not to mention that even more than that, people use it check if they are connected to internet.. ). But what we people haven't realized is that with the growing technology Google has also upgraded itself a lot. Is not just a mere search engine, not any more.

Following are some really cool tricks to perform with Google to make your life easier..
1) Definitions

Find out the definition of any word by typing 'define' (without quotes) followed by the word you want the definition for. For example, typing: define geek would display the definition of the word geek.

2) Local search

Visit Google Local, enter the area you want to search and the keyword of the place you want to find. For example, typing: restaurant at the above link would display local restaurants.

3) Phone number lookup

Enter a full phone number with area code to display the name and address associated with that phone number.

4) Find weather and movies

Type 'movies' or 'weather' followed by the zipcode or city and state would display the current weather conditions or movie theaters in that area. For example, typing weather 84101 gives you the current weather conditions for Salt Lake City, UT and the next four days. Typing movies 84101 would give you a link for show times for movies in that area.

5) Track airline flight and packages

Enter the airline and flight number to display the status of an airline flight and it's arrival time. For example, type: delta 123 to display this flight information if available.

Google can also give a direct link to package tracking information if you enter a UPS, FedEx or USPS tracking number.

6) Translate

Translate text, a full web page, or search by using the Google Language Tools.

7) Pages linked to you

See what other web pages are linking to your website or blog by typing link: followed by your URL. For example, typing link:http://www.example.com/ displays all pages linking to Computer Hope.

8) Find PDF results only

Add fileType: to your search to display results that only match a certain file type. For example, if you wanted to display PDF results only type: "dell xps" fileType:pdf -- this is a great way to find online manuals.

9) Calculator

Use the Google Search engine as a calculator by typing a math problem in the search. For example, typing: 100 + 200 would display results as 300.

10) Stocks

Quickly get to a stock quote price, chart, and related links by typing the stock symbol in Google. For example, typing: msft will display the stock information for Microsoft.
