VARIOUS KINDS COMPUTER DEVICES
Science Lovers - Because I really
like computer science then In this post we will discuss about some of the components needed to
build a computer device that is ideal. Please enjoy.
Central Processing Unit (CPU)
The CPU is the most important part of a
computer because it is the brain of the computer. CPU or sometimes called
microprocessor or processor is the central data processing and control computer
work. Therefore, the performance of a computer is highly dependent on the
performance of its CPU.
Example CPU:
Memory
Memory is a computer hardware that serves
to store information before or after processed by the processor. Such
information may be in the form of commands and data. For storage, the memory
has storage spaces in which each of the storage space has its own address in
the form of numbers that point to a specific location in memory.
Memory is divided into two parts, the
internal memory is called RAM (Random Access Memory) and external memory called
ROM (Read Only Memory).
Examples of memory:
Media Storage
1. harddisk
Hard drive is a storage medium with the
largest capacity. At present, the hard drive can you store data up to 400
gigabytes and will continue to grow with the rapid advances in computer technology.
Hard disk rotation speed determines the speed of access to any data.
Examples disk:
2. Diskette
Diskette used to store data as well
as the hard drive. The difference floppy only capable of storing data up to 1.4
MB. The surplus, floppy disks used to store and move data from one computer to
another.
Examples diskette:
3. Flash Drive
Flash drives replacing the floppy
position due to its smaller size and have larger capacities such as 128 MB, 256
MB, 512 MB, 1 GB, 2 GB.
Examples of flash drives:
4. CD-R
CD-R (Compact Disc-Recordable) can store
data that is big enough up to 700 MB. However, the speed is still less appeal
to the hard drive.
Examples of CD-R:
5.DVD
DVD (Digital Versatile Disc) has a
storage capacity large enough compared with the CD-ROM are the same size large.
DVD has excellent storage kealitas, therefore DVD is usually used to store
movies.
DVD Example:
Motherboard
The motherboard is a computer device that
serves as the other devices, such as processors, memory, VGA Card, Sound Card,
and LAN Card. Each device has its own slot allowing the device attached to the
motherboard.
Examples motherboard:
VGA Card
VGA Card is functioning computer
equipment to convert the digital signal into an image signal. VGA Card allows
the data in digital form is displayed in the form of an image on the screen.
Examples VGA Card:
Keyboard
The keyboard is a set of buttons that
serve as input for computer media. Each of the keyboard keys have specific
functions.
Example keyboard:
9. Mouse
Mouse is a device used to explore the
program, select a command, and execute a command.
Example mouse:
Monitor
The monitor is a device that gives a
visual display output to the computer user. We can see what is being done by
the programs or the computer screen. Computer displays messages, information,
or ask for input to computer users through the display on the monitor screen.
Examples monitor:
Printer
The printer is an output device that is
used to produce molds from the computer into shape. The mold can include
documents, pictures, and documents are accompanied by drawings.
Printer example:
Speaker
Speaker is the hardware to produce sound.
The other type of speaker is a headset or earphones.
Examples speakers:
UPS
UPS is a hardware device that supplies
power to the computer in the event of termination of electrical current. UPS
storing energy in the battery.
Example UPS:
