An email virus consists of malicious code distributed in email messages to infect one or more devices. This malicious code can be activated in numerous ways: when the email recipient clicks on an infected link within the message, opens an infected attachment or interacts with the message in some other way.
Spam Emails
Another famous method to spread email viruses is spam mails. Spam mail is designed in such a way that the users could not resist themselves for clicking on them. The subject line is made catchy and attractive, for example - 70% Off on your Favorite Product. Users are presented with fake offers that would get activated only if they click the given link. That link is unsurprisingly malicious and can trigger the malware installation.
Interesting Facts:
1. The malicious programs or codes spread through emails are widely known as 'email viruses.'
2. Avoid opening the email attachments sent from unknown sources. The file extensions .dll, .exe, .com, .pif, .js, .scr, .dot, .xls, .xlt, etc., can be virus carrier. Always be careful while downloading such files from emails.

Startup is a location that stores programs to load each time a computer starts. Windows can run one or more of your applications automatically each time it starts by placing a shortcut to the application in the Startup folder.
At startup, Windows looks in various locations for programs to run; however, the Startup folder is the simplest way to add your own application. To add an application to the Startup folder, do the following:
1. Launch Explorer.
2. Right click program icon.
3. Select Create Shortcut option.
4. Drag shortcut into appropriate folder below:
Windows 7
c:\Users\[username]
\AppData\Roaming
\Microsoft\Windows\Start Menu
\Programs\Startup
Windows 10
1. Press Windows Key+R for Run command
2. Type shell:startup.
(Startup folder appears)
Interesting Facts:
For any Windows user who wants to have a program startup each time their computer starts, a shortcut can be placed in the Windows Startup folder.

laplet (LAPtoptabLET) is a Windows laptop computer that can be switched to a tablet style. Also called a "2-in-1," the screen folds back all the way around, turning the machine into a rectangular slate. Convertibles are heavier and thicker than regular tablets without keyboards.
Convertible vs. Hybrid
The convertible's screen remains on the unit, whereas the screen on a hybrid laptop (a "detachable") is removed to become the tablet. However, the terms "convertible" and "hybrid" are used interchangeably for both kinds of these double-duty machines.
Interesting Facts:
Yoga Laptop Lenovo features its Yoga brand of convertibles. The screen folds back entirely to become a tablet-style computer.

(What You See Is What You Get) Pronounced "wiz-ee-wig." WYSIWYG refers to displaying text and graphics on screen the same as they print on paper. The term was popular in the days before graphical user interfaces (GUIs) were the norm and everything on screen was character based. As systems changed from text to graphics, WYSIWYG became the norm. However, there may always be discrepancies between what appears on screen and what is printed because monitors typically have much lower resolution than printers.
Live Preview
A view of the final version of a document is called Live Preview. Most applications automatically provide a live preview. As you make changes to the data on the page with regard to fonts, colors, placement etc., the changes occur in real time. However, some applications offer a live preview mode that lets users quickly see how the changes would look before applying them.
Interesting Facts:
WYSIWYG (pronounced wiz-ee-wig) is a type of editing software that allows users to see and edit content in a form that appears as it would when displayed on an interface, webpage, slide presentation or printed document. WYSIWYG is an acronym for "what you see is what you get."

AirDrop is a proprietary wireless ad hoc service in Apple Inc.'s iOS and macOS operating systems, introduced in Mac OS X Lion and iOS 7, which can transfer files among supported Macintosh computers and iOS devices by means of close-range wireless communication.
With AirDrop, you can wirelessly send your photos, videos, websites, locations, and more to other nearby devices and Mac computers (iOS 7, iPadOS 13, OS X 10.10). AirDrop transfers information using Wi-Fi and Bluetooth—both must be turned on.
When someone attempts to send you a file using AirDrop, you see an alert and a preview on your Mac or iOS device. You must tap Accept or Decline on your device to receive the file or refuse the transfer. This prevents nearby users from sending files directly to your device without your permission.
Interesting Facts:
AirDrop doesn't keep the history of files being sent or received, so you cannot see what you have sent to other devices, be it an iPhone or Macbook.

Cache memory, also called cache, is a supplementary memory system that temporarily stores frequently used instructions and data for quicker processing by the central processing unit (CPU) of a computer. The cache augments, and is an extension of, a computer’s main memory. Both main memory and cache are internal random-access memories (RAMs) that use semiconductor-based transistor circuits. Cache holds a copy of only the most frequently used information or program codes stored in the main memory. The smaller capacity of the cache reduces the time required to locate data within it and provide it to the CPU for processing.
When a computer’s CPU accesses its internal memory, it first checks to see if the information it needs is stored in the cache. If it is, the cache returns the data to the CPU. If the information is not in the cache, the CPU retrieves it from the main memory. Disk cache memory operates similarly, but the cache is used to hold data that have recently been written on, or retrieved from, a magnetic disk or other external storage device.
Interesting Facts:
Cache is the fastest and smallest component of memory in a computer system. The registers are fast storage elements present in a very small amount in the computer processor.

Skimming is a method used by identity thieves to capture payment and personal information from a credit card holder. Several approaches can be used by fraudsters to procure card information, with the most advanced approach involving a small device called a skimmer that reads the information stored in a card's magnetic strip or microchip.
How Skimming Works?
Skimming can occur anytime a cardholder uses an electronic payment card at a brick-and-mortar (a traditional street-side business) location. Fraudsters can obtain information in various ways, and the technology that they use is becoming more sophisticated and challenging to detect.
Skimming allows identity thieves to capture information from a cardholder that can be used to make fraudulent transactions. Some fraudsters may simply photocopy or take digital photos of information that can be used fraudulently.
Thieves can also build skimming devices that can be used at automated teller machines (ATMs) and other point-of-sale locations such as gas stations. Skimming devices can be installed on an ATM with cameras and overlay touchpads can be added to capture individual personal identification numbers. Gas stations are another target where skimming devices can be easily installed since card readers are often outside at the gas pump and separate from a checkout.
Interesting Facts:
1. Skimming is an illegal practice used by identity thieves to capture credit card information from a cardholder surreptitiously.
2. Fraudsters often use a device called a skimmer that can be installed at gas pumps or ATM machines to collect card data.
3. Some machines act like point-of-sale technology. An acquired card is swiped, and a touchpad allows the user to enter a security code.
4. Card users are warned to keep their cards in their sight at all times and to cover the pin pad when inputting security codes at ATMs.

(chat roBOT) software that provides a text or verbal interaction with the user in their native language in order to provide help on a website. Also called a "chatterbot" and "virtual consultant", the chatbot is designed to emulate normal human responses. Chatbots are often extremely limited in scope. However, with use, the software may be designed to improve over time.
Chatbots vs. Virtual Assistants
The terms "chatbot" and "virtual assistant" are increasingly used synonymously; however, chatbots preceded virtual assistants and generally provide suggestions or answers to questions about a specific topic or product. Chatbots are generally embedded within an app or Web page, whereas virtual assistants such as Alexa, Siri and Cortana are stand-alone, ask-anything programs.
Chatbot First, Human Second
A chatbot often functions as the first attempt at solving a problem before the user is permitted to activate a chat or phone call with a human representative.
Interesting Facts:
1. Most Chatbot Conversations Start With “Hi”.
2. Chatbots use two important security processes – Authentication, with which chatbots verify the user identity and authorisation, which grants the user access to information or function. These processes ensure that the person using the device is legitimate and not fraudulent.
