The pollute of your laptop

The tech industry has a dirty little secret: it has toxic waste of its own. Phones and computers contain dangerous metals like lead, cadmium and mercury, which can contaminate the air and water when those products are dumped.

It’s called electronic waste, or e-waste, and the world produces a lot of it: 20 to 50 million tons a year, according to the UN — enough to load a train that would stretch around the world. The U.S. is by far the world’s top producer of e-waste, but much of it ends up elsewhere — specifically, in developing nations like China, India and Nigeria, to which rich countries have been shipping garbage for years. There the poor, often including children, dismantle dumped PCs and phones, stripping the components for the valuable — and toxic — metals contained inside. In the cities like the southern Chinese town of Guiyu, they work with little protection, melting down components and breathing in poisonous fumes. What can’t be recycled is simply dumped, turning already poisoned rivers into toxic sludge. It’s all done in the hope of earning a few dollars from the detritus of the clean digital economy.

What is Hard Disk

What is Hard Disk – Boot Disk – External Hard Drive – Hard Drives – Hard Drive- Hard Disk – Network Storage – Platter

Today, hard disk is most commonly used storage device in personal computers and laptop computers. Most application programs and operating systems require hard disk for installation and operation. A hard disk, also called a hard disk drive. It contains one or more metal platters mounted on a central spindle, like a stack of rigid diskettes. A hard disk is actually, a stack of platters. Each platter is coated on both sides with magnetic material. Both surfaces of each disk or platter are used to store information except for the top and bottom platters.

Optical Storage Devices

Optical Storage Devices – CD DVD Burner -Computer Hard Drive – Data Recovery – Storage Devices – CD Rom – DVD CD – DVD Storage – CD Rewritable – CD R – CD RW

Today, the most widely used and reliable storage devices are the optical storage devices. These devices use laser technology to store and read data to and from the disk. The most popular optical storage devices are: CD-ROM drive, DVD-ROM drive, CD-Recordable drive, CD- Rewritable drive etc. Today, all PCs also contain one CD-ROM drive. These devices use laser light to write/read data to and from the optical storage media such as CDs (compact disks). A large amount oil data, software, movies and songs etc. can be stored on a single CD. Some optical storage media is read-only while others are read and write.

How recursive DNS queries work.

The basic concept of DNS name resolution is fairly simple. Every Web site is assigned a unique IP address. In order to access a website, a client needs to know what the site’s IP address is. Of course users don’t usually enter an IP address into their Web browser, but rather enter the site’s domain name instead. In order to access the requested website, the Web browser must be able to convert the site’s domain name into the corresponding IP address. This is where DNS comes into play. The client computer is configured with the address of a preferred DNS server. The requested URL is forwarded to the DNS server, and the DNS server returns the IP address for the requested website. The client is then able to access the requested site.

As you can see, the name resolution process is pretty cut and dry. However, there are countless websites in the world, and new sites are being created every day. It is impossible for your DNS server to know the IP address of every single website. When a DNS server does not know the address for a requested site, it uses one of two methods to determine the site’s IP address.

The preferred name resolution method is called recursion. Generally speaking, recursion refers to the process of having the DNS server itself to make queries to other DNS servers on behalf of the client who made the original request. In essence, the DNS server becomes a DNS client. Some administrators prefer to disable recursion for performance reasons. If recursion is disabled, then the DNS server uses a process called iteration to resolve the name request.

Bad Credit And The Term Issue

People with bad credit usually have difficulties in obtaining the funding they desire. It is not that they can not obtain funds at all. It is just that the conditions of the loans, lines of credit and other financial products available are not sufficiently advantageous to provide the results that someone seeking financing wants. The term issue is usually a particular problem that affects most applicants with bad credit.

When we talk about the term issue we refer to the fact that the repayment programs or schedules of most financial products available for those with a bad credit score or history are usually not as long as they would desire. The consequence of this fact on the other variables of the loan such as interest rate, amount of the monthly payments and loan amount are usually also disadvantageous for bad credit applicants.
