3. Digital cameras. Digital cameras record and store images or video in digital form.

2. Printers and plotters. Plotters are a type of hard-copy output device used for general design work.

Bus is a communication system that transfers data between components inside a computer, or between computers. The purpose of buses is to reduce the number of "pathways" needed for communication between the components.

Port serves as an interface between the computer and other computers or peripheral devices.

There are two main types of computer ports: physical and virtual.

13. Types of printers.

· 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.

· Laser printers work through electronically charging a piece of paper with the digital images selected for printing. They use a type of powdered ink called toner, which sticks to the paper where it has an electronic charge and is permanently melted to the paper.

· Ink-jet printer. An ink-jet printer works through spraying minute dots of ink onto paper to create an image. The dots use a combination of different colours to create photo-realistic images.

· 3D printers

Color printers use 4 basic colors: CMYK (Cyan, Magenta, Yellow, BlacK)

14. Types of monitors.

15. How to increase speed of computer?

Very philosophic questionJ

16. Classification of software.

Software is the computer programs that govern the operations of the computer.

We can indicate 2 types of software. They are System software and Application software

Systems software is the set of programs designed to coordinate the activities and functions of the hardware and various programs throughout the computer system.

System software includes:

· operating system

· drivers

· codecs

· utilities

· shells.

Application software consists of programs that help users solve particular computing problems.

17. Classification and main functions of operating systems (OS).

An operating system, or (OS) is a set of computer programs that control the computer hardware and act as an interface with application programs.

Common desktop operating systems include Windows, Mac OS X, and Linux. While each OS is different, they all provide a graphical user interface that includes a desktop and the ability to manage files and folders. They also allow you to install and run programs written for the operating system.

Common mobile OSes include Android, iOS, and Windows Phone.

The collection of programs that make up the operating system performs a variety of activities, including the following:

• Performing common computer hardware functions

• Providing a user interface and input/output management

• Providing a degree of hardware independence

• Managing system memory

• Managing processing tasks

• Providing networking capability

• Controlling access to system resources

• Managing files

18. Main features of OS Windows.

Microsoft's line of Windows operating systems is the most used in the world. Windows 2.0 was the first to feature Control Panel, a tool that allowed the user to navigate a graphical interface to adjust settings on the computer.Software became "plug and play," which allowed users to insert diskettes (and eventually CD-ROM discs) into their computer and install software more easily, something that was still at the time difficult on other operating systems. Windows 7 features full 64-bit support, remote media streaming, and touchscreen functionality. Taking a cue from Apple's OS X operating system, Windows 7 features "Sleep" and "Resume" functionality. The search system has been made quicker and easier to navigate. Memory usage has also been optimized to ensure faster and more reliable performance. Windows 7 has also been redesigned for better power management through the reduction of background activities, less power-hungry media drives.

19. File systems of Windows.

A file system is a method of organizing files on physical media, such as hard disks, CD's, and flash drives. Windows makes use of the FAT, NTFS, exFAT file systems.
