NAS means Network-attached storage

Network-attached storage (NAS) is a file-level computer data storage server connected to a computer network providing data access to a heterogeneous group of clients

NAS is specialized for serving files either by its hardware, software, or configuration. It is often manufactured as a computer appliance – a purpose-built specialized computer. NAS systems are networked appliances which contain one or more storage drives, often arranged into logical, redundant storage containers or RAID.

Network-attached storage removes the responsibility of file serving from other servers on the network. They typically provide access to files using network file sharing protocols such as NFS, SMB/CIFS, or AFP. From the mid-1990s, NAS devices began gaining popularity as a convenient method of sharing files among multiple computers. Potential benefits of dedicated network-attached storage, compared to general-purpose servers also serving files, include faster data access, easier administration, and simple configuration.

The hard disk drives with NAS in their name are functionally similar to other drives but may have different firmware, vibration tolerance, or power dissipation to make them more suitable for use in RAID arrays, which are sometimes used in NAS implementations. For example, some NAS versions of drives support a command extension to allow extended error recovery to be disabled. In a non-RAID application, it may be important for a disk drive to go to great lengths to successfully read a problematic storage block, even if it takes several seconds. In an appropriately configured RAID array, a single bad block on a single drive can be recovered completely via the redundancy encoded across the RAID set. If a drive spends several seconds executing extensive retries it might cause the RAID controller to flag the drive as down whereas if it simply replied promptly that the block of data had a checksum error, the RAID controller would use the redundant data on the other drives to correct the error and continue without any problem. Such a NAS SATA hard disk drive can be used as an internal PC hard drive, without any problems or adjustments needed, as it simply supports additional options and may possibly be built to a higher quality standard (particularly if accompanied by a higher quoted MTBF figure and higher price) than a regular consumer drive.

The Cloud is Cloud Computing

Cloud computing is the most common name, often colloquially called the cloud. The Cloud has been brought to the attention of most people by the new works. The Cloud makes it possible for several people to work at home or on the go, no matter where a person is physically located.

HTTP means Hypertext Transfer Protocol

The HTTP protocol is designed for transporting HTML files. It is used to get a page on the Internet from the Web server to the user (above you see if it is good also stand: http://www.wat-betekent.nl/wat-betekent-http/). Today's browsers take this for granted, and want http://to automatically filter out. The protocol determines which queries a client can make to the server, and which answers can be returned. In 1997, the HTTP standard jacked up to version 1.1. Read More

What does DDoS mean?

DDoS means distributed Denial of Service

With a DDoS attack, a lot of computers (often from different places around the world) make a lot of connection requests to a server. Because that server then receives as many requests in one time, the server (and therefore website) is often slow, or no longer reachable at all. To achieve this, botnets are often used. Read More

Failwhale is the Twitter error page

Twitter was regularly offline in the past by a too large amount of users who would like to use the service at the same time. The page you saw then was a whale that was lifted by birds from the water: This is the Failwhale. Meanwhile, many improvements have been made to the platform, but it still occurs that the servers are out (especially during upgrades or major events). The Failwhale has become a household name and is also often used if another site doesn't do it anymore. Failwhale images from Flickr
