Often when we connect to the internet were browsing indexed pages through some well-known search engine, usually Google. But beneath the so-called normal internet lurks deep and dark web. You might have heard of the deep web and dark web if you have some geeky friends and we are here to explain what exactly is the deep and dark web. The first thing to know is that the deep and dark web is not the same thing and they coexist separately from one another, you could say that beneath the deep web lies the dark web, yet another layer of the internet. So let us explore first the deep web. What is exactly a deep web?

Deep web, hidden web, or invisible web

as sometimes referenced are part of worldwide web not indexed by search engines, meaning that engines do not basically see and index content of deep web sites. The content of the deep web is hidden behind HTTP forms and includes many very common uses such as webmail, online banking, private or otherwise restricted access social-media pages and profiles, some web forums that require registration for viewing content, and services that users must pay for, and which are protected by paywalls, such as video on demand and some online magazines and newspapers. The content of the deep web can be located and accessed by a direct URL or IP address but may require a password or other security access to get past public website pages. While it is not always possible to directly discover a specific web server's content so that it may be indexed, a site potentially can be accessed indirectly (due to computer vulnerabilities). To discover content on the web, search engines use web crawlers that follow hyperlinks through known protocol virtual port numbers. This technique is ideal for discovering content on the surface web but is often ineffective at finding deep web content. For example, these crawlers do not attempt to find dynamic pages that are the result of database queries due to the indeterminate number of queries that are possible. It has been noted that this can be (partially) overcome by providing links to query results, but this could unintentionally inflate the popularity of a member of the deep web.

Dark WEB

The dark web is the World Wide Web content that exists on darknets: overlay networks that use the Internet but require specific software, configurations, or authorization to access. Through the dark web, private computer networks can communicate and conduct business anonymously without divulging identifying information, such as a user's location. The dark web forms a small part of the deep web, the part of the Web not indexed by web search engines, although sometimes the term deep web is mistakenly used to refer specifically to the dark web. The darknets which constitute the dark web include small, friend-to-friend peer-to-peer networks, as well as large, popular networks such as Tor, Freenet, I2P, and Riffle operated by public organizations and individuals. Users of the dark web refer to the regular web as Clearnet due to its unencrypted nature. The Tor dark web or Onionland uses the traffic anonymization technique of onion routing under the network's top-level domain suffix .onion.

Dark & Deep WEB difference

The dark web has often been conflated with the deep web, the parts of the web not indexed (searchable) by search engines. The dark web forms a small part of the deep web but requires custom software in order to access its content. This confusion dates back to at least 2009. Since then, especially in reporting on Silk Road, the two terms have often been conflated, despite recommendations that they should be distinguished. Darknet websites are accessible only through networks such as Tor ("The Onion Routing" project) and I2P ("Invisible Internet Project"). Tor browser and Tor-accessible sites are widely used among darknet users and can be identified by the domain ".onion". While Tor focuses on providing anonymous access to the Internet, I2P specializes in allowing anonymous hosting of websites. Identities and locations of darknet users stay anonymous and cannot be tracked due to the layered encryption system. The darknet encryption technology routes users' data through a large number of intermediate servers, which protects the users' identity and guarantees anonymity. The transmitted information can be decrypted only by a subsequent node in the scheme, which leads to the exit node. The complicated system makes it almost impossible to reproduce the node path and decrypt the information layer by layer. Due to the high level of encryption, websites are not able to track the geolocation and IP of their users, and users are not able to get this information about the host. Thus, communication between darknet users is highly encrypted allowing users to talk, blog, and share files confidentially.

Darknet

The darknet is also used for illegal activity such as illegal trade, forums, and media exchange for pedophiles and terrorists. At the same time, traditional websites have created alternative accessibility for the Tor browser in an effort to connect with their users. ProPublica, for example, launched a new version of its website available exclusively to Tor users.

Cyclic Redundancy Check Error - What is it?

To begin with, Cyclic Redundancy Check is basically an error checking technique. This technique is used for data verification. It detects accidental changes in the data. It is used by computers to specifically check the data stored in the hard drive or optical disks (DVD’s and CD’s). The Cyclic Redundancy Check error occurs when the data being verified on the hard drive or optical disks is corrupt. Symptoms for this error code include program lock-ups, slow PC performance, inability to run and execute the desired program, system freeze and shutdown and startup issues.

Error Causes

The Cyclic Redundancy Check error code occurs due to the following reasons:

• Cluttered hard disk
• Registry corruption
• Misconfigured files
• Unsuccessful program installation

All these causes points towards registry issues and poor PC maintenance. The registry is the main database of the computer. This part of the PC saves practically every activity you perform on it including activities like application installation and deletion and web browsing to name a few. With time and frequent PC usage, the files generated from every activity you execute on your system begin to load the registry. These include even the unnecessary files like junk files, internet files and files of applications that you’ve uninstalled. All these files overload the registry and acquire a lot of hard disk space. And when you don’t remove these files on your system, eventually it leads to file misconfiguration, cluttered disk, and registry corruption. New program versions that you want to install and run on your system also don’t function because the files of the old program version still saved in the registry.

Further Information and Manual Repair

As the Cyclic Redundancy Check Error causes data corruption on the hard disk, it is advisable to fix this error right away. The reason is that it can have serious consequences. It can lead to data loss, fatal crashes, and system failures. When it comes to resolving Cyclic Redundancy Check Error, there are two ways to fix it:
