What is difference between DSL and ADSL?

Question Asked : What is difference between DSL and ADSL? What type of connection is commonly used in India? (Question asked on my Youtube Page) 

Asymmetric digital subscriber line (ADSL) is a type of digital subscriber line (DSL) technology, a data communications technology that enables faster data transmission over copper telephone lines than a conventional voiceband modem can provide. ADSL differs from symmetric digital subscriber line (SDSL).

ADSL works by utilizing frequencies that are not used by a voice telephone call. A splitter or DSL filter allows a single telephone connection to be used for both ADSL service and voice calls at the same time. ADSL can generally only be distributed over short distances from the telephone exchange typically less than 4 kilometres, but has been known to exceed 8 kilometres if the originally laid wire gauge allows for further distribution.

At the telephone exchange the line generally terminates at a digital subscriber line access multiplexer (DSLAM) where another frequency splitter separates the voice band signal for conventional phone network. Data carried by the ADSL are typically routed over telephone company's data network and eventually reach a conventional Internet Protocol network.

Thus the upload signal is weakest at the noisiest part of the local loop, while the download signal is strongest at the noisiest part of the local loop.

ADSL is a type of DSL where the upstream and downstream speeds differ (hence the "asymmetric" part). There are many variations of DSL technology for different types of application (HDSL, SDSL, etc). 

ADSL

ADSL is a broadband connection technology which utilizes existing copper wired telephone networks. ADSL uses a wide range of frequencies over an existing telephone line to deliver much higher speeds than standard 56k modem (between 10 and 140 times faster). It is also possible to use your phone while online. 

DSL

DSL stands for Digital Subscriber Line. Generally if you have a DSL connection, you are getting it right from the phone company. DSL is more like the older 'modems' in that they do use the standard copper phone lines that are in your house. DSL requires that there be a special switch installed at your local phone company's main routing station. DSL also has a limitation of a 4 mile radius. One of the cool features of DSL is that you do not need to have a 'special' line installed - you can be surfing the internet and talking to someone on the phone all on the same line. This is because DSL uses a high frequency that does not affect the normal use of your phone. 

There are two commonly type of DSL, DSL (also known as SDSL) and ADSL. DSL or SDSL is the more expensive, but offers the most bandwidth. The S in SDSL stands for Symmetric or synchronous, which means that the bandwidth of both upstream (sending data) and downstream (receiving data) are the same speed. The actual speed you get depending upon the package you sign up for, and how far away from the switch you are. The most common speeds are 256k (256kilobits)/second and 1Mb (1megabit)/second. ADSL (Asynchronous Digital Subscriber Line) is the same as SDSL, but the upstream bandwidth is smaller than the downstream. This version of DSL is generally more affordable than SDSL. Common ADSL speeds are 256kb downstream - 96kb upstream, 1mb downstream - 256kb upstream.

DSL was developed and patented in 1988 by Bell Communications Research, Inc. The main advantages of DSL at the time were the speed it offered and the fact that, for the first time, it allowed people to use Internet and phone service at the same time. The main disadvantage was that the digital signal's strength decreased as distance from the provider's central office increased.

Although it uses the same wiring as previous technologies, DSL sends information digitally. This greatly increases the amount of information that can be sent at once. ADSL is the most common type of DSL connection. 

Note :

• The opposite of ADSL is SDSL, which stands for symmetrical digital subscriber line. 
• SDSL provides a high-speed data connection that gives equal priority to upload and download speed. 
• Other types of DSL include Internet protocol subscriber line, rate-adaptive digital subscriber line, Uni-DSL and Etherloop.

• Display : 15.6 inch
• Graphics : Intel HD Graphics 3000
• RAM : 4GB DDR3
• Storage : 500GB hard disk drive
• Battery : 6-cell

Lenovo G570 can be equipped with a Blu-ray drive instead of a DVD reader/writer.

Transfer your system files or Data on new SSD or hybrid hard disk

Use cloning software that comes with the SSD to copy of your original hard drive onto the SSD. You can copy your software, settings and documents to new SSD. Steps as follow : 

• Step 1) Turn off your computer and connect the transfer cable to the SSD.
• Step 2) Plug the other end of the cable into a USB port of your computer. Start your computer and insert the disk with cloning software included with your SSD.
• Step 3) Boot from the CD. To do this, right from the start, press the F1, F2, F12 or Del depending on your computer. A message is typically displayed on the screen. In the menu that appears, select your CD with the arrow keys and press Enter. The computer boots from the CD. Click on Accept.
• Step 4) Click the Let’s Get Started. Initially select the source disk, that is to say, the internal hard drive to your laptop and click Next.
• Step 5) Then select the destination disk, that is to say the SSD and click Next.

Now that you have copied your entire system and your files on the SSD, you are ready to replace your hard drive with SSD in your laptop. 

How to install Hard Drive in Lenovo G570 :

On the bottom of your Lenovo G570 laptop, find the hard drive door to access the hard drive.

• Step 1) Loosen four screws securing the cover on the bottom. Lift up and remove the cover.
• Step 2) Remove two screws securing hard drive caddy to the laptop chassis. Slide the hard drive assembly in the direction opposite to the SATA connector and then carefully lift it up in order to remove it from drive bay.
• Step 3) To separate the hard drive from the caddy you will need to remove four screws that fix these two parts together.
• Step 4) There could be an Aluminium adhesive tape between both parts making their disassembly more difficult so be careful. You will have to transfer the mounting bracket and Aluminium hard drive shield to the new SSD.

After replacing the HDD you will have to reinstall the operating system and transfer important data from older Hard Drive to new one.

There is second way to install other hard drive in Laptop :

You can use HDD Caddy to replace the DVD-Drive from the Lenovo G570 series for a second hard drive (or SSD). Add a second hard drive to your laptop using your laptop's optical drive. This device can fit in a "standard" optical drive bay found in laptop computers. Simply pull out your DVD drive and replace it with our optical bay hard drive caddy. 

You have to remove DVD Drive and plug the adapter (plus hard drive) in slot.

How to install RAM memory in Lenovo G570 :

Both memory modules can be accessed on the bottom of the laptop.

To remove any currently installed memory module just spread the latches in the direction opposite to the memory slot. The memory module will pop up at about 45 degree angle and can be safely removed from the slot. (As shown in Video)

Lenovo G570 can take up to 8GB RAM. You can install up to 4GB RAM module into each slot.

Lenovo G570 use RAM of PC3-10600 DDR3 SDRAM SODIMM 204 pin.

Note : Lenovo G570 has to run a 64-bit OS to be able to use all 8GB RAM.

Note : Before you begin any procedures, turn off the laptop, unplug the power adapter and remove the battery. Laptop parts are very sensitive to static electricity so ground yourself before touching anything inside you laptop by using grounding strap or touch a metal pipe.

You can use SATA2 or SATA 3 SSD, as both will work at the same rate, as your interface is SATA2, but the advantage of the SATA3 is that you can use this drive in the future in another laptop that does have the SATA3 interface, thus it will give greater speed in that laptop. SATA2 interface has speed of 3Gbps while SATA 3 uses 6Gbps.

Why my computer is not booting up?

Question : Computer is well connected and has power supply. But still computer is not booting up? Why?

Solution :

There are many reasons for not booting of your computer. It can be due to following common reasons.

1) RAM : RAM is not properly installed on your computer’s motherboard. And it make beep sound twice from motherboard’s speaker.

2) Processor : The processor is not properly installed on motherboard.

3) Harddisk Connection : The hard disk with operating system is not properly connected to motherboard, or hard disk does not get enough power from power source of computer i.e. SMPS. (This is most reason when your computer do not boot on starting.)

4) Operating System : The operating system of computer (example Microsoft Window or Mac etc) is corrupted or need to reinstall or repair by operating system’s DVD. 

5) BIOS Setting : Lastly, your booting option is selected incorrect in BIOS of your motherboard of computer. That means, in BIOS, computer is having option to boot from other source of booting rather than of hard disk, example like DVD ROM or floppy or USP device etc.

Our Experience : The main reason of computer is not booting due to RAM error or Hard disk connection. 

If your computer is showing BIOS menu on your LED screen, that mean, it’s processor or RAM is well connected on motherboard.

If it show Boot Error on your LED’s screen, it means, it is not connected your Hard disk or not allowed to access your hard disk in motherboard’s BIOS.

Only computer expert can guess actual reason for error in your computer for not booting up.

Easy Steps for Installing DDR2 RAM (Hindi) (1020p HD)

RAM is sensitive to static charges and should be handled carefully. Never touch the metal conductors and only handle RAM by their edges. 

Depending on its architecture, there will always be at least one notch in a RAM, but never more than two.

RAM modules are keyed with little notches that fit over corresponding tabs in the RAM slots. Before inserting the RAM module, make sure that the notches and tabs are correctly lined up.

Installing RAM is easy to do and probably the easiest task in building a computer.

There will be one or two indentations on your RAM (depending on type of RAM). These indentations need to face the notches on the RAM slots. Now take the RAM carefully and push them into RAM slot, the little RAM clicks should snap into place.

If the BIOS screen comes up on your monitor and there is not a series of beepings then your RAM is successfully installed. To check if all your RAM is recognized by your computer, then you need to go to the BIOS setup, which will display the amount of RAM that is recognized.

This video can be useful for a new user who wants to change their DDR2 RAM in their Pentium computers. Same steps are applicable for installing other type of RAM (DDR1 or DDR3) in their respective Motherboards. (Voice : Hindi)

Intel Core i5-2450M

The Intel Core i5-2450M is a second generation dual core processor for laptops. The Intel Core i5-2450M is based on the Sandy Bridge architecture and features HypertTreading technology to handle 4 threads at once that increases the processor performance by 20%.

The Intel Core i5-2450M offers a smaller level 3 cache of 3 MB, 512 kB level 2 cache and 128 kB level 1 cache. This Intel Core i5-2450M dual-core processor has a base clock speed of 2.5 GHz but because of TurboBoost technology it can speed up to 2.8 GHz when 2 cores are active and 3.1 GHz when only 1 core is active, TurboBoost can be achieved when the thermal and electrical aspects are met. The clock speed of Intel Core i5-2450M is just higher by 100MHz compared to Core i5-2430M.

The Sandy Bridge architecture is the successor of the Arrandale architecture and the most remarkable improvements of this architecture is the improved Turbo Boost 2.0 and the integration of the graphics and memory controller into the 32nm CPU core. This is the equivalent of the APU technology introduced by the AMD.

The i5-2450M offers an integrated graphics card (Intel HD Graphics 3000) which is clearly faster then the older Intel HD Graphics in the Arrandale CPUs. As the new GPU is included in the CPU, it is also manufactured in 32nm and shares the fast level 3 cache with the CPU cores (using a new ring bus).  The Intel Core i5-2450M’s integrated GPU is clocked at 650 to 1300MHz because of the GPU TurboBoost. The Intel Core i5-2450M dual core processor has 35 Watt TDP; this includes the integrated GPU and memory controller.

Due to the improved architecture and the new Turbo Boost 2.0, the average performance of the Core i5-2450M is higher than a similar clocked Arrandale Core i5.

Intel HD Graphics 3000

Intel’s HD Graphics 3000 is the integrated graphics in most of the Sandy Bridge notebook processors (HD Graphics 2000 is featured in some of the desktop Sandy Bridge processors).

The HD Graphics 3000, improves upon the earlier Intel HD Graphics (Intel HD Graphics Media Accelerator).  While it is still short of ability to play most of the modern fast moving games at full resolution, Intel is approaching gradually towards it.

The HD Graphics 3000 still lack the DirectX. It also trails in performance when compared to the integrated graphics in Llano APUs from Intel.

The HD Graphics 3000 has 12 Execution Units while the HD Graphics 2000 has 6 Execution unit. This results in substantially faster performance for HD 3000.

Intel HD Graphics 3000 is significantly better than the HD Graphics (the integrated graphics in the 1st generation core i processors) with a much improved architecture.

The Radeon HD 6520G from AMD, is better than the Intel HD 3000 graphics as it support DirectX11.
