CD read / write disks support the creation of CD-R and CD-RW discs, and feature the CD-ROM drive. These
drives use a low power laser "burning" of data in the active layer of the disc.
CD-R (write CD) discs are 'write once - they are writing data can not be erased or altered. However,
multisessions can be created and additional data can be added.
CD-RW (rewritable CD) discs can be written or delete several times. This two-pass process, so they
typically take twice as many CD-R disc production.
CD-RW discs, as a rule, three speed ratings - one for reading the disc, one for writing CD-R discs, and
the second for writing CD-RW discs. Speed ratings range from 1 to 52x, which means that 1x CD read /
write in "real time" - 52 minutes audio CD takes about 52 minutes to create 1x speed and speed about 1
minute 52x.
Data can be written to disk in various formats to create a CD, data, CD, CD or video file from the
CD-ROM. Audio CD, to play in most standard CD audio equipment, video and photo discs will play on many
players in the consumer DVD.
Many writers CD (also known as "vodka"), is directed to function as a combination DVD-ROM drive.
Most DVD-RW discs and CD-RW capabilities.

Memory.
Memory - Memory can be very confusing, but as a rule, one of the most simple piece of equipment in
addition to your computer. It is common to confuse the memory chip ROM. For example, the difference
between memory and storage is the difference between the table where the actual work (memory), a closet,
where the final product is stored (disk). Can be used to add a little more confusion, the hard disk and
memory, when the program needs more chips can provide.
Memory or RAM memory, which is used for temporary storage of information, which is also considered.
Processing more detailed information on more RAM in your computer needs.
Use one of the first home computers 64 kilobytes of RAM (Commodore 64). Today, modern computers should
be at least 64 MB (recommended 128 MB or more) to run the operating system or Windows 10 with modern
programs.
RAM chips have different size and speed, and can usually be expanded. For computers with 512 kilobytes
of memory, which can be expanded to a maximum of 640 KB. But perhaps the most modern computers the
memory can be expanded by adding or replacing memory chips depending on the CPU you have and the type of
memory device uses your computer. Memory chips, ranging in size from 1 MB to 4 GB. As computer
technology changes such as changes in memory, as well as making old memory chips obsolete. Check your
computer manual to find out what type of memory on your computer before buying the new memory chips.

Scanner.
Scanners, Scanners allow you to transfer pictures and photos on your computer. scans 'Scanner' icon from
the top down, on one line time and passes on the computer as a series of bits or a bitmap file. You can
take images and use them in the paint, and send it by fax or print it. With optional Optical Character
Recognition (OCR) software that can convert printed documents such as newspaper articles, and text that
can be used in a text editor. Most scanners use TWAIN software that makes the scanner accessible to
other software applications.
Digital cameras allow you to capture digital photos. Images are stored on a memory card or disk that can
be transferred to your computer. Some cameras can also capture audio and video.
Issue - the issue of houses chips and circuits that are running on your computer. Desktop models usually
sits under the control and tower models beside. They come in many sizes, including desktop, mini, midi,
and full tower. There is usually room to expand or add components at a later date. Removing the cover to
this issue can be found covered with leaves, the empty slots for adding cards. There are different types
of slots including IDE, ASI, USB, FireWire and PCI slots.
Depending on the laptop may be the type of room for expansion. Most notebook computers, as well as
connections or ports that allow expansion or connection of external and peripheral devices, such as
monitoring and portable hard drives or other devices.

Modem
Modem - a modem is used to translate information transferred through telephone lines, cable or line of
site wireless connection.
Shelf stands for modulate and demodulate the signal from analog to digital change, using computers, in
which use of phones and then back. Digital modem direct transfer of digital information, without
changing the analog.
Modems are measured by the speed that information is transferred. This tool is called the Baud rate
dimensions. Initially work quickly under the 2400 Baud modem speed but are analogous to today's
standards 56.000. Cable, wireless or digital subscriber line can transfer more information faster to
300000 Baud rates and above.
Modems use error correction, which corrects for transmission errors by constantly check whether the
information was received correctly or not, and compression, which allows faster data transfer speed.
Information is transferred in packets. Each package is checked for errors and re-sent if there is an
error.
Anyone who has used the Internet have noticed that sometimes the information travels at different
speeds. Depending on the amount of information that is transferred, the information will arrive at the
destination in time is different. The amount of information that can travel through the line is limited.
This restriction is called traffic.
There are many other variables associated with communication technology using computers, much of which
is covered on the Internet.

Mointor and Printer
Monitor - shows the monitoring information on the screen when writing. This is called the output
information. When the computer needs more information to display a message on the screen, usually
through a dialog box. Monitors come in many types and sizes. Solution sets a unit of the monitor
display. Resolution can be adjusted to control the screen ..
Most desktop computers use a device with a cathode ray tube or LCD screen. Most of the use of laptop
computers with liquid crystal display monitor.
To take full advantage of the programs today with full-color graphics and animation, computers need a
monitor with a color screen or video card.
Printer - a printer receives information on the screen, and transferred to paper or hard copy. There are
many different types of printers with various levels of quality. Three basic types of the printer; dot
matrix, inkjet and laser.
Dot matrix printers work like a typewriter ink transfer from the tape to the paper with string or
'Matrix' of small nails.
Printers, ink jet printers work like a bitmap, but unleash a torrent of ink from the cartridge directly
on paper.
Laser printers use the same technology to a photocopier using heat to transfer ink on paper.

Types of Computer Hardware.
Computer hardware is a physical piece of hardware inside a computer program. This is in contrast to
computer programs or data that change frequently, modified or removed in a computer. Computer hardware
is not changed and is stored in devices such as read only memory (ROM) where it does not change easily.
Most computer hardware is embedded and so is not visible to ordinary users. Here are the different types
of hardware in a computer.
- Motherboard: This is the central or primary circuit board making a complex electronic system such as a
computer. A motherboard is also known as a key board, logic board or system board.
- Central processing unit, a CPU is the main component of a digital computer that interprets
instructions and process data in computer programs.
- Random Access Memory: a memory stored data can be found in any way. RAM is considered the main memory
of the computer where the work area to display and manipulation of data is used.
- Basic Input Output System: BIOS, software programs to download, execute and control the computer.
- Power supply: Power supply electricity to provide an output load or group of taxes.
- Video Display Controller: It converts the logical representation of visual information in a signal
that can serve as input for a secondary display is used.
- Business Computer: It is used for data or power between computer components to transfer to a computer
or between computers.
- CD-ROM drive: It contains data available from computer
- Floppy Disk: This is a data storage device
- Zip Drive, "This is a medium-capacity removable disk storage system.
- Hard Disk: This is a non-volatile data storage system that stores data on a magnetic surface layer on
the hard disk clean.
