Mobile Emulator

What does Mobile Emulator mean?

A mobile emulator is a resource for emulating or simulating a mobile device or smartphone environment. It allows developers to test URLs or other technologies on a mobile device’s operating system and display interface.

Part of the utility of a mobile emulator is related to responsive design, the idea that websites, Web projects and software products need to be able to work well on mobile operating systems and interfaces. A mobile emulator typically focuses on one specific mobile platform, for example, Apple iOS or Android.

Some mobile emulators are available online. By inputting a URL and choosing a device, users can get effective simulations over the Web. Other mobile emulators are sold out of the box or otherwise used offline.

Security Architecture

What does Security Architecture mean?

Security architecture is a unified security design that addresses the necessities and potential risks involved in a certain scenario or environment. It also specifies when and where to apply security controls. The design process is generally reproducible.

In security architecture, the design principles are reported clearly, and in-depth security control specifications are generally documented in independent documents. System architecture can be considered a design that includes a structure and addresses the connection between the components of that structure.

The key attributes of security architecture are as follows:

Zeus Trojan

What does Zeus Trojan (Zbot) mean?

The Zeus Trojan is a kind of Trojan that infects Windows-based computers and steals banking and financial information. When it infects a computer, it looks for personal data such as email usernames and passwords as well as online financial and banking records associated with the personal information. The data are then sent to remote servers and then collected by the hacker who can then proceed to commit financial fraud by using the stolen information.

The Zeus Trojan is also known as Zbot.

The Zeus Trojan is used by hackers to steal information relating to online banking. The stolen information is then sent to remote servers controlled by the hackers, who then use it to log on to the victims’ accounts to make unauthorized (however, in this case, the system sees the transaction as authorized because of correct log-in information) money transfers to various hidden accounts and “money mules” to hide the electronic trail and make it hard for authorities to determine exactly where the money went.

Windows Minidump

What does Windows Minidump mean?

A Windows minidump is a small file that is generated every time the Windows operating system unexpectedly encounters an error, such as during “blue screen of death” (BSoD) crashes. The file contains information regarding the nature of the error, such as the state of the system right before and possibly during the crash. This contains information like running services and processes as well as the resources being used by each.

A Windows minidump is a file created to help a user diagnose the circumstances behind a crash, specifically in the Windows operating system. It contains rich information about the system right before and during the crash to help pinpoint the problem. Information like applications and programs running, resource consumption and processor state can be seen in the minidump file. A minidump may not contain as much information as a full crash dump file, but usually suffices to help quickly diagnose a problem. Other applications are also able to create minidumps that contain varying types of information.

Zip Drive

What does Zip Drive mean?

A Zip drive is a medium-capacity and portable magnetic disk storage system launched by Iomega in the mid-1990s. It was popular at the time of launch as cost per storage unit was lower than that of hard disks, and it could store a larger amount of data than a floppy disk. The Zip drive was capable of fast data transfer and was durable and reliable. The rise of other devices that later came to market, such as USB drives, were favored over the Zip drive and Zip disk, and these became obsolete soon afterward.

The Zip drive was available in 100- and 250-MB capacities. The initial versions of the drive could be connected to a computer by means of a parallel, SCSI or IDE port. The later versions had a USB interface and were thus simple to connect, being plug and play. The Zip drive was PC and Mac compatible and came with a manual and related software that provided ease-of-use features. The drive installed itself on a computer and would be assigned a new drive letter to distinguish itself from other drives. It could handle high-capacity Zip disks and had a large drive slot to fit the disks. The Zip drive also contained a retro-reflective spot for identifying the proper disk media in order to prevent damage to the disk and drive.

At the height of its popularity, the Zip drive was considered a larger version of the floppy drive and certain manufacturers included Zip drives internally in their devices. It was favored in the graphic arts vertical market and was also economical for home users at the time of launch for storing large data. Zip drives were reportedly prone to click-of-death failures, which potentially resulted in media and data loss.

Ultra High Definition

What does Ultra High Definition (UHD) mean?

Ultra high definition (UHD or 4K/8K) is a display resolution standard of at least 3840 by 2160 pixels (8.3 megapixels; 4K), which is double that of Full HD’s 1920 by 1080 (2 megapixels). 3840 by 2160 is only the floor value, and resolutions being put on various screens range from this size up to 4096 by 3112 for 4K and up to 7680 by 4320 (33.2 megapixels) for 8K. The Consumer Electronics Association (CEA) clarified in October of 2012 that UHD would refer to any display with a 16:9 aspect ratio and a minimum of 3840-by-2160 pixel resolution.

Ultra high definition is an umbrella term used for display in television and portable electronics such as smart phones and tablets, most commonly referred to as 4K resolution and, subsequently, 8K resolution. This was pioneered and proposed by NHK Science and Technology Research Laboratories and approved and then defined by the International Telecommunications Union (ITU).

UHD results in a very crisp and fine image owing to the high pixel count and allows for manufacturers to make bigger TVs without compromising on image quality. Of course, this also requires that the content be in the same resolution for the quality to be retained. But despite its size, UHD, which is commonly used for television as UHDTV with an aspect ratio of 16:9 or 1.78:1, is still lower than the movie projection industry standard of 4096 by 2160 at 19:10 or 1.9:1 aspect ratio. This means that most movie contents released for UHDTVs are still in a letterbox format.

Cryptocurrency

What does Cryptocurrency mean?

Cryptocurrency is a type of digital currency that uses cryptography for security and anti-counterfeiting measures. Public and private keys are often used to transfer cryptocurrency between individuals.

As a counter-culture movement that is often connected to cypherpunks, cryptocurrency is essentially a fiat currency. This means users must reach a consensus about cryptocurrency’s value and use it as an exchange medium. However, because it is not tied to a particular country, its value is not controlled by a central bank. With bitcoin, the leading functioning example of cryptocurrency, value is determined by market supply and demand, meaning that it behaves much like precious metals, like silver and gold.

Gavin Andresen, bitcoin’s technical lead, told Forbes.com that cryptocurrency is designed to bring back a “decentralized currency of the people,” taking centralized banks out of the equation. Because bitcoins must be cryptographically signed each time they are transferred, each bitcoin user has both public and individual private keys.
