English abbreviations and slang in chats, instant messengers and SMS. What is TF memory card? What is TF card? Features of the

TF card - what is it? TF cards, or T-Flash cards, are miniature cards known as TransFlash. TF cards were first introduced in 2004 by SanDisk as the world's smallest memory card upgraded by NAND MLC for technology management.

TF cards have been specially designed for mobile phones and small electronic gadgets. Like all memory cards, they have different speeds and storage capacities.

TF-card - what is it? Description

TransFlash has been announced by the SD Card Association as the third form factor memory card in the Secure Digital family after SD and miniSD memory cards. After the adoption of the TransFlash standard, the corporation changed the name of the product solution to microSD. TF card volume - what is it? MicroSD has the same dimensions and specifications as TransFlash and therefore both memory cards are fully compatible with each other.

TransFlash (TF) and microSD cards are almost the same and can usually be used interchangeably, except that microSD has support for SDIO mode, while TF does not. SDIO allows microSD cards to perform memory-free tasks such as Bluetooth, GPS and

TF card size

TF card capacity - what is it? The physical size of the device is 15mm x 11mm x 1mm. The TF card comes in various storage capacities such as 128MB, 256MB, 512MB, 1GB, 2GB, 4GB, 6GB, 8GB, 16GB, 32GB and 64GB.

What's the difference between TF card and Micro SD card?

A TF card or TransFlash is similar in appearance to a Micro SD card, but technologically different. The main difference is as follows:

Transfer rates (read and write speeds).

Memory size availability. The maximum capacity of the TF card is 128GB, the SD card is 2TB.

SD cards have more transistors.

The SD card has a switch on the security segment, whereas TransFlash does not have such a function.

There is a difference in size between TF card and SD card. TF card - 15 mm × 11 mm × 1 mm. SD card - 24 mm × 32 mm × 2.1 mm.

Structural difference

TF card slot - what is it? A small memory card is usually used as a flash drive. A TF card can also be called an electronic storage device that stores digital information. Used in any portable electronic gadgets such as laptops, tablets, computers, MP3 players, PDAs, game consoles, electronic keyboards, synthesizers, mobile phones and digital cameras.

Application

Micro SD card (2GB), also called TF card, is applied with an optional adapter to install directly into the memory card slot of the computer. Trans Flash for mobile phones allows you to:

expand the memory on your mobile phone;

transfer content to a new device and share photos / ringtones / music;

quickly and easily transfer files from your PC to external media.

Each memory card comes with an SD adapter, which allows it to be used as a full-size secure digital card in SD-enabled devices.

Information reading speed

The speed of an SD card is usually judged by its sequential read or write speed. The sequential aspect of performance is most important for storing and retrieving large files (relative to block sizes embedded in flash memory) such as images and multimedia. Small data (such as file names, sizes, and timestamps) fall under a much lower random access speed limit, which can be a limiting factor in some use cases.

TF card efficiency - what is it? New families of SD cards, which include the TF card, improve card performance by increasing the transfer speed. Regardless of the bus speed, the card can signal to the host that it is “busy” until a read or write operation is complete. Observing a higher speed is to ensure that the card limits the use of the busy indicator.

What is TF card? Features of the

TF cards have a number of features. Let's list the main ones:

• Security - Cards can protect their content from erasure or modification, prevent unauthorized users from accessing, and protect content using digital rights management.
• Disable Write Commands - The host device can force the TF card to become read-only in order to reject subsequent commands to write information to it. There are both reversible and irreversible host commands for this.
• Open and Locked Cards - User can assign most full size TF cards in read-only mode with a sliding tab that covers the label on the card.

Change Password - The host device can lock the card using a password up to 16 bytes, usually provided by the user. A locked card usually communicates with the host, except that it rejects commands to read and write data. A blocked card can only be unblocked by providing the same password. After providing the old password, the host device can supply a new password or disable the lock. Without a password (usually in case the user forgets it), the host device can force the card to erase all data on the card for future reuse (except for the data on the DRM card), but there is no way to gain access to the existing data.

Youth slang is a subject of discussion in any country, it is often criticized, or even simply scolded. But let's look at it from a different angle and try to understand that language begins with communication, and if slang helps someone communicate, then it is worth paying attention to.

Have you ever found yourself in an English chat or read SMS sent by young native speakers? Those who first encountered this phenomenon may receive a slight shock. Even if you still thought you knew English well, you may find yourself in a very unpleasant position. Is it any wonder this, if even English-speaking parents do not always understand what their children are writing (and sometimes saying). Abbreviations and slang words in English are radically different from their Russian counterparts. If in Russian correspondence you can often find shortened versions of the spelling of familiar words (such as bush - you will; vyhi - days off; dviglo - engine), then in English several peculiar types of abbreviations can be distinguished:

1. Conventional abbreviations, they are abbreviations, for example IDK - I don "t know. There are a lot of such abbreviations, it is quite difficult to remember everything - there are thousands of them. Often the native speakers themselves guess about the meaning of this or that abbreviation only from the meaning of correspondence in a chat or forum.

2. Words and phrases using numbers. It can be difficult for people who have just started to learn the English language right off the bat to read and understand such phrases in online communication: c u l8r (see you later)... At the initial stage, you should not dwell on these numbers and letters, just perceive the sounds - and you will hear already familiar words and phrases. 2day - - today (today); m8 - [m] - mate (buddy, partner, partner).

3. Another type of letter from the lazy inhabitants of the English-speaking part of the Internet is words shortened in the process of colloquial speech: kinda (kind of), wanna (want to), lemme (let me). The specificity and importance of these abbreviations is that we constantly hear them in the oral speech of Americans and British, so they should be paid special attention to.

By the way, American slang differs significantly from British, and then there is Canadian and Australian. How many more local words and expressions? Probably no one knows this. We made a pitiful attempt to put together a small, but perhaps the most popular part of slang abbreviations into a table for acquaintance and perhaps even for memorization.

The table can be sorted by English and Russian alphabets in both directions.

In the era of development of computer technology, a person can no longer do without a smartphone or tablet. The demand for various mobile carriers is constantly growing, everyone wants to get the most capacious and high-speed one.

Today we will talk about memory cards - the most common accessories for mobile devices. Each gadget now has a special slot for them. We are interested in TF memory card, what it is and what parameters it has.

Memory card format and its features

There are many formats, as electronics companies have previously sought to develop their own type of device. Now they are trying to unite them.

The oldest format is SD Card, developed at the end of the last century, which is distinguished by its large size. Later, it was repeatedly refined and now there are three form factors:

• standard SD card
• mini SD
• micro SD

What is TF?

The standards are gradually becoming obsolete, although they were previously commonly used in cameras. Micro SD was created by SanDisk in 2004 under the name TransFlash. The abbreviation TF, which you periodically observe on the Internet, has gone precisely from those times. Such cards are small in size, but they are inserted not only into smartphones with small slots, but also into larger equipment using special adapters.

Increase in size

A few years later, the format underwent changes, it was modified and increased in volume, renaming it SDHC. Even later, SDXCs appeared, with the largest storage capacity.

There are several more formats - Smart Media, Microdrive and others. They are gradually losing their position in the market, and are most often used in specialized devices.

Speed ​​classes

Another important aspect that affects the quality of the device is speed. It is measured in megabytes that the card is able to receive in one second. When there were too many formats, a special classification was introduced.

Grades from 2 to 16 are now common. The higher - the faster the device works. More importantly, each gadget has its own requirements for the speed of the card. In the case of mobile phones, purchasing a Micro SD slower than the fourth class is pointless, and for expensive SLR cameras you need at least a tenth. Requirements for this parameter continue to grow every year, and sluggish models become obsolete and give way to more technologically advanced counterparts on the market.
