The four main categories of communication are
- Verbal – It is a method that uses speech in the form of speaking to convey a message or information. It is the most popular and effective mode of communication, usually practised during video conferences, phone calls, presentations, one-on-one conversations, and meetings. It supports both nonverbal and written communication.
- Nonverbal – It is basically a practice of gestures, facial expressions, and body language to send information. It can be implemented intentionally and unintentionally when communicating. For instance, a person can smile unintentionally when they hear an interesting piece of information or a pleasant idea.
- Written – It is all about typing, printing symbols, numbers, letters, and writing to send a piece of information. Sometimes used to record information for evidence or reference purpose. In general, the written style of communication is used in books, blogs, pamphlets, memos, and letters to share and spread information. In the workplace, e-mail is a common example of written communication.
- Visual – It uses art, photographs, sketches, graphs, charts, and drawings, to pass on the information. It is used especially during presentations to present to give a visual effect and support written or verbal communication.

A wearable computer is any small technological device capable of storing and processing data that can be worn on the body. Wearable computers are designed for accessibility and convenience, as well as improvements to workplaces by making information quickly and readily available to the wearer.
Common examples of how wearables are worn include on wrists as watches or jewelry, around necks similarly to a lanyard or necklace, on the user's head, in the user's shoe or carried in a bag. Wearable devices continue to evolve and become more efficient, manageable and adaptive to the everyday needs of users.

True
Dot-Matrix Printers
The dot-matrix printer uses print heads containing from 9 to 24 pins. These pins produce patterns of dots on the paper to form the individual characters. The 24 pin dot-matrix printer produces more dots that a 9 pin dot-matrix printer, which results in much better quality and clearer characters. The general rule is: the more pins, the clearer the letters on the paper. The pins strike the ribbon individually as the print mechanism moves across the entire print line in both directions, i-e, from left to right, then right to left, and so on. The user can produce a color output with a dot-matrix printer (the user will change the black ribbon with a ribbon that has color stripes). Dot-matrix printers are inexpensive and typically print at speeds of 100-600 characters per second.
Drum Printer
A drum printer consists of a solid, cylindrical drum that has raised characters in bands on its surface. The number of print positions across the drum equals the number available on the page. This number typically ranges from 80-132 print positions. The drum rotates at a rapid speed. For each possible print position there is a print hammer located behind the paper. These hammers strike the paper, along the ink ribbon, against the proper character on the drum as it passes. One revolution of the drum is required to print each line. This means that all characters on the line are not printed at exactly the same time, but the time required to print the entire line is fast enough to call them line printers. Typical speeds of drum printers are in the range of 300 to 2000 lines per minute.
Chain Printers
A chain printer uses a chain of print characters wrapped around two pulleys. Like the drum printer, there is one hammer for each print position. Circuitry inside the printer detects when the correct character appears at the desired print location on the page. The hammer then strikes the page, pressing the paper against a ribbon and the character located at the desired print position. An impression of the character is left on the page. The chain keeps rotating until all the required print positions on the line have filled. Then the page moves up to print the next line. Speeds of chain printers range from 400 to 2500 characters per minute.

"Scanner"a device that optically scans images, printed text, handwriting or an object and converts it to a digital image. Commonly used in offices are variations of the desktop flatbed scanner where the document is placed on a glass window for scanning. Hand-held scanners, where the device is moved by hand, have evolved from text .Mechanically driven scanners that move the document are typically used for large-format documents, where a flatbed design would be impractical.

File Transfer Protocol (FTP) is a standard Internet protocol for transmitting files between computers on the Internet over TCP/IP connections. FTP is a client-server protocol where a client will ask for a file, and a local or remote server will provide it.
The end-users machine is typically called the local host machine, which is connected via the internet to the remote host—which is the second machine running the FTP software.
