Pengertian Kabel Sata & ATA ( Understanding Sata & ATA Cables )

ATA

ATA (Advanced Technology Attachment) standard is a standard interface that allows you to connect a storage device to the PC. ATA standard was developed on May 12, 1994 by ANSI. ATA standard was originally intended to connect the hard drive, but an extension called ATAPI (ATA Packet Interface) has been developed to other storage devices (CD-ROM drive, DVD-ROM drives, etc.) to the ATA.
ATA standard storage device can connect directly to the motherboard for ribbon cable, which generally consists of 40 parallel wires and three connectors (usually a blue connector for the motherboard and a black connector and a gray connector for the two storage devices).

SATA

SATA (Serial Advanced Technology Attachment) is a computer designed typically to transfer data between the motherboard and data storage media, such as hard disk and optical drive in the computer. Main advantage of using a SATA hard disk is faster data transfer, can move or add to the device during operation, thinner cables so that the air cooling process can be streamlined, and many other advantages.
SATA transfer data sequentially or via serial cable and also developing their own techniques SATA disk connected to the motherboard without the system master or slave, so that the SATA cables can only be used on a single hard disk.

A striking difference from ATA to the SATA HDD, Namely: 1. Sata cables using wires smaller than PATA (15-pin). Adapter of serial ATA is able to accommodate the transfer of data at higher speeds than with simple ATA. Although using smaller cables, but SATA is faster than PATA. If the speed reaches 133 Mbps ATA, SATA has the speed of a sequel, which is 150 Mbps (SATA I), 300 Mbps (Sata II) and 600 Mbps (SATA- 600 / SATA III), while ATA uses cables max width and a transfer rate of 133Mbps.
2. SATA has many advantages (eg, native command queuing) which causes it to have more speed and the ability to perform work in ling¬kungan multitask compared to ATA. ATA and SATA is the system transfer data to and from disk. ATA was still using the parallel system so now known as PATA. Because parael use of cord lot, which the IDE cable.
3. SATA is developing Serial ATA uses a system that works so efficient multiplex wiring. ATA theoretical maximum data transfer 133mbps while SATA 150Mbps. To SATA2 can reach 300 mbps

Pengerian UPS (Uninteruptible Power Supply)

UPS is an acronym for Uninteruptible Power Supply. UPS has the sense that the computer hardware device that functions to provide power supply when the mains voltage is not functioning (standstill, power outages). So, UPS will only work if a power outage. That is, just as a backup UPS.

UPS is quite a role because it can provide electricity supply for a few minutes. A fairly short time can be used to shut down the computer normally. It's certainly better than dying suddenly due to power outages (will damage the hard disk).

UPS has a function as a backup power source was an emergency. That is, UPS serves to provide the electrical supply during a blackout in order to keep the computer from unwanted things. For instance, when the power goes out and there is UPS, then the computer will be safe from damage to computer equipment or computer data is lost due to not get saved. It will all be resolved if there is a UPS device.

Moreover, in the UPS device also contained stabilizer. This stabilizer has the functionality to stabilize the power flow into the computer. Thus, the CPU can last longer than usual because the electric current flowing to the CPU can be stabilized.

Similarly to the author to convey understanding of UPS and related functions. We hope to provide clarity for those who want to explore computer technology information.

And Type Definition Computer Monitor

 1. CRT (Cathode Ray Tube)
CRT (Cathode Ray Tube) or in the Indonesian language is a type of cathode ray tube display the oldest and most widely used by the public. CRT originally discovered by German physicist Ferdinand Braun in 1897 and became known as the "Braun Tube".
CRT is a vacuum tube containing an electron gun (Electron guns) and a heating element (heater), which serves to accelerate and deflect the electron beam (electron beams). This is because in a vacuum hot, the electron beam is easy to move from the cathode to the anode.
CRT monitor is a monitor second generation of computer monitors is the first generation of computer monitors in the modern era.
Currently the interest in CRT monitors are becoming obsolete though CRT monitors are still produced. The reason why users start leaving the CRT monitor is due to its large and heavy that it requires extra space to put this monitor. Definition CRT monitors in general is the monitors 'convex' or 'monitor tubes'.
Advantages of CRT Monitors:
- Prices are relatively cheaper
- More accurate and vivid colors
- Flexible monitor resolution
- Easy maintenance
- Free of dead pixels, ghosting and viewing angle
Disadvantages CRT Monitor:
- Consumption of electricity greater
- Damaging eye
- Ray radiation that result in less good for the people, the brain, eyes and hair cells
- Depending on refreshrate
- Vulnerable distortion, glare and flicker
- The dimensions are large and heavy that it takes up less space
      2. LCD (Liquid Crystal Display)
Monitor LCD (Liquid Crystal Display) monitor that is collated by using "liquid crystal". LCD is a digital display technology that produces an image on a flat surface (flat) with a ray in the liquid crystal and colored filters, which have a polar molecular structure, sandwiched between two transparent electrodes.
Technology found since 1888, is the processing of liquid crystals contain a chemical liquid, in which the molecules can be arranged if given the electric field as the molecules of metal when given magnetic field. When set correctly, light can pass through the liquid crystal.
The workings of the liquid crystal LCD monitor is structured like a sandwich between pieces of polarized glass. Neon lights behind the panel emits light that passes through the first substrate. The electrical charge to make the cells crystal aligning different tones allow light to pass through the second substrate. The result is a stunning colors displayed on the screen, so no cathode tubes, no radiation, no more head or eye pain.
Excess consumption of LCD monitors is the lack of energy used also have a sharper image contrast compared to CRT. Definition LCD monitor refers to the use of variants of pixels (dots of color of light) that does not emit its own light as well as CRT monitors. In LCD technology light source comes from white fluorescent lamps are arranged evenly on the rear of the arrangement of pixels (liquid crystal) earlier numbering in the millions of pixels to form an image. Polar liquid crystals through which the electrical current will change due to the influence of magnetic field polarization arising and therefore will only let a few colors forwarded while other colors are filtered.
Excess LCD Monitor:
- The image quality is crisp and clear
- Produce more realistic colors
- Rays emitted by the LCD does not tire the eyes
- The consumption of electricity more efficient
- Frendly user display settings (easy)
- Dimensions are thin and light so it saves space
- Anti-glare technology (no shadow)
- There is no radiation emitted
Disadvantages LCD Monitor:
- The LCD screen tends to be more sensitive
- Viewing angle is limited, unlimited color depth and gradation of color less
- Display pictures in resolution only good nativenya
- Response time and ghosting
- Prices are more expensive, need extra care and caution dead pixels
      3. LED
Monitor LED (Light Emitting Diode) has the same technology as the LCD with the further development of LCD display which has the effect of enhancing the color displayed is more variation in color.
Differences physically on the computer LEDs generally lies in a leaner shape / thinner. In some types of LED functions and features that are more complete than LCDs, such as digital touch screen capability, Digital TV internet, digital TV tuner. While in general the difference between LED and LCD lies only in the lighting system which uses LED backlight technology. In contrast to LCD using CCFL Backlight (Cold Cathode Fluorescent Lamp) in the Indonesian language "manifold fluorescent neon light", the LED monitor can save electricity consumption up to 50-70% compared to the LCD with the ability to produce extremely sharp images.
Advantages of LED Monitor:
- The image contrast very sharply to millions of pixels
- Consumption of electricity is more efficient than LCD
- Minimum use of LEDs are longer
- The size of a more slim lighter than LCD
- The lighting is better than LCD
- More environmentally friendly
Disadvantages LED Monitor:
- Prices are more expensive than LCD

      4. Plasma
Plasma Display Panel (PDP) or in Indonesia known as the Plasma TV or Plasma Monitor is a type of monitor that combines CRT with LCD technology. With the resulting technology, capable of making LCD screens with thinness resemble and can be as wide viewing angles CRT.
The term and concept of Plasma TV technology introduced in 1936 by an expert of Physics. Monitor plasma using a full color flat panel phosphor to display images, so the combination and the resulting color reproduction is excellent and interactive. PDP itself is derived from the use of plasma cells, which are Fluorescent lamp, as the basic lighting of the television screen. A Plasma TV utilizing millions Plasma cells are placed between two panes of glass screen. Each cell contains a combination of noble gas and a small amount of mercury to be evaporated and given an electrical charge and form a plasma to fluoresce. Colors produced from phosphorus contained in the cell, where in each cell would contain phosphorus three main color types, namely: Red, Green, and Blue, or commonly known as RGB. The difference voltage given to each cell also produce color combinations that exist.
Excess Plasma Monitor:
- Produce black better than LCD TV
- Contrast ratio is high (1: 2,000,000)
- The viewing angle is wider
- Refresh Rate and Response Time is fast, minimizing the blurring image display
- Sleek
Disadvantages Plasma Monitor:
- The still image is displayed for a long time will cause burning and ghosting
- The image quality will continue to decrease with the duration of use
- Prices are relatively expensive
- Having a large pixel pitch size
- Has a very large weight
- Power consumption and high operating temperatures
- Cell plasma for representatives of each pixel of the image only has an on / off so that the color reproduction is much more restricted than the type of CRT or LCD

Understanding Power Suply

Power Supply in Indonesian power supply is the hardware which is useful for supply / provide direct electrical voltage to components that require a voltage. For example, motherboard, hard drive, fan, etc.

Power supply can obtain energy from various types of energy sources, including electricity transmission systems, energy storage devices such as batteries and fuel cells, electromechanical systems such as generators and alternators and solar power converters.

The power input power supply in the form of alternating current (AC) power supply, the need to change the AC voltage so DC (current line), because the computer devices will only operate with a DC current. Power supply in the form of a box which mostly placed above the rear of the casing.

In addition, the power supply has kenektor cables each cable connector that has a different function and is needed by the computer. At the end of this post you will find some of the cable connector Power Supply.

How it Works Power Supply

When we press the power button on the chassis, which will happen is Power supply will perform checks and tests before letting the system run. If testing is successful, Power Supply sends a special signal on the motherboard called with good power.

Function Power Supply

Power Supply function on the computer is to provide or supply electric currents previously changed from the opposite form of electrical current or AC, into an electric current that is in line or commonly called the DC current.

Power supply supplying DC electric current required by the hardware in the computer. As for some of the hardware that requires a DC electrical current that is the hard drive, fan, motherboard and others.

This function is similar to a UPS (Uninterruptible power supply), but its difference is batrai UPS can be used for backup, and will be very useful when the power suddenly dies. To better understand what a UPS ??.

Function Power Supply By Type Connector

Power supply has many connectors and each of the connector has a different function. Although most cable has the same power supply voltage, but each of the connectors are grouped by function.

To know more about different types of connectors Power Supply, then below are some pictures of the connectors that you can learn.
