the largest capacity hard drive | hardisk

harddisk

The NSA is building an indoor area of ​​92,903 m2 as a storage hard drive and costs about 2 billion dollars. The plan of this place will be able to store data at 1 Yottabytes predicted will be realized in 2015.
Well, certainly in question Yottabytes right? How much does a Yottabytes it?

- 1,000 Gigabytes (GB) = 1 terabytes (TB)
- 1,000 terabytes (TB) = 1 petabytes (PB)
- 1,000 petabytes (PB) = 1 exabytes
- 1000 Exabytes = 1 Zettabyte
- 1,000 Zettabytes = 1 Yottabytes
How, they already know now how does one Yottabytes? That certainly might be able to store all data that exist in this world.
Hard drive of that size would also be making us hard to imagine how much it takes to reach that capacity if they use the hard drive capacity of 1 TB per piece. If calculated they would use about 1,000 billion hard drives. (Gile really ...!)
But from what we read, most likely the NSA uses a much larger hard drive since the NSA always use the most advanced technology that is usually not in the market like they could use a hard drive with a capacity of 25 -100 TB per piece.

Motherboard

Motherboard

Function of Motherboard
Central controller that regulates the work of all the components attached to it.
Manage the electrical power on every component of a PC.
Data traffic are all governed by the motherboard, ranging from storage devices (hard disks, CD-ROM), data input devices (keyboard, mouse, scanner), or a printer to print.

TERMS OF MOTHERBOARD
1. BIOS

2. Bus

3. Clock Speed

4. FSB

5. Heatsink

6. Overclocking


Components MotherBoard

-Chipset

-AGP

Memory-Connector

Processor-socket


-CMOS


External Devices-Port (serial, parallel, audio, USB)

Power Supply-Connector (power supply, fan)

Casing-Connector

IDE & Floppy-connector

Determining the motherboard is recognizing its size:
There are several types of motherboard size, ranging from AT, Micro ATX and ATX. These measures are called form factor. In general, the motherboard, motherboard ATX now using the technology. Motherboardmotherboard standard class is a type of micro ATX, motherboard, while mid-end or high end of most uses ATX form factor. Although his form factor is different, every innards motherboard has the same standards, so this measure only affects the choice of casing to be used.

Bios and ROM

Bios and ROM

Bios and rom
The BIOS is closely related to the ROM, because most of the BIOS contained in the computer hardware is stored in the ROM, both PROM, EPROM, EEPROM, Flash ROM, or other types of ROM. However, after 1995, EEPROM and Flash Memory is more widely used than other types because the BIOS ROM contained in the two types of ROM is easily erased and inscribed again so that it opens the possibility of updating the BIOS. BIOS updates are often required by computer users for several reasons, among others:

1. To support the newer processors, for new computer users just replace the old processor with a new type of processor to get better performance.
2. To support the new devices are paired because the old BIOS not provide support for new types of devices.
3. The existence of an annoying bug in the old BIOS.
4. Or various other reasons.
The motherboard manufacturers often provide a new BIOS version to improve their products or to get rid of annoying bugs. The existence of the bugs in the BIOS usually only known after the BIOS was released. Therefore BIOS that had the bug needs to be updated with a newer BIOS version that is the issue of improvement from the old BIOS.
BIOS update process must be done carefully and cautiously. The update process is not right can lead to malfunction of the motherboard (motherboard died), because the firmware is used to aid the boot process (BIOS) does not work. The damage is not physical damage motherboard components, but the damage to the BIOS software (firmware) which is in EEPROM or Flash Memory.
Most BIOS at the moment, has a region (locations) in the EEPROM or Flash Memory Boot Block termed a deliberate 'protected' and can not be upgraded. When the computer is turned on, the Boot Block is always executed first. Code from the Boot Block will verify the BIOS to see if the BIOS in a normal condition or damaged. If the BIOS in the normal condition (not broken), the computer immediately execute the BIOS itself. Conversely, if the BIOS was damaged, the boot block will display a message on the screen for computer users to do programming (charging) the BIOS again by using the same BIOS version or the BIOS is updated with a better version. BIOS program that is used to update normally stored in the floppy disk, flash memory is stored inside the programmer and the BIOS image.

Function Prosesor , (CPU) | Type Prosesor | They form Prosesor

Prosesor (CPU)

Function Processor (CPU)
Processor is a function for processing data received from the input (input). He also described as the "brains" to the computer where each data going through the processor to produce output (output), which is fitting. Without the processor, the computer can not function, in accordance with another name namely Central Processing Unit or CPU summary.
For example, when you taip this blog address, then the processor will receive feedback and dealing with computer components such as RAM, hard disks, motherboards, and other components to produce the output / results you want. If the processor does not work, then the computer components are also not able to function.
They form Prosesor
In the first, installed in accordance rekabentuk processor slot. But now, all in accordance rekabentuk processor installed in socket. Generally, there are now two expenditures namely Intel and AMD processors. Rekabentuk luarannya almost the same, namely a square-shaped and have a lot of pins as connectors to the motherboard. There rekabentuk namely Intel's latest LGA775 socket that has no pins, otherwise the motherboard that has a pin-pin connector to be connected to the processor.
Processor Selection
If the impact of re-election to the tips motherboard, processor and socket type processors are the first things that need to be sure before buying the motherboard. In short, the processor is the most important components of a computer perkakasan before buying computer components to another. Need to be reminded, too, his habit perkakasan processor is the most expensive computer.
