About USB 3.0

usb 3You’d have to know if USB 2.0 will be replaced by USB 3.0 started in 2010.

I also cannot wait to be there in Indonesia …. follows the explanation

USB 3.0 Specification:

Transfer Rate
USB 3.0 data transfer speeds of about 3200 Mbits/s (3.2 GBits/s or 400 Mbytes/s), and in theory can achieve 4.8 Gbit/s. This speed is 6 to 10 times faster than USB 2.0 maximum speed.

Data Transfer
USB 3.0 data transfer technology introduces two-way (full duplex), so it can read and write data simultaneously (simultaneously). USB 2.0 and earlier do not support this bi-directional technology.

Power
Electric voltage is derived from 4.4 V to 4V, then the flow also improved (to 150mA), so in addition to more energy efficient, a USB 3.0 port can be used 4-6 and increase the recharging device.

Power Management
Power management is better than USB 2.0, thus supporting the idle, sleep and suspend.

Physical Forms
Edge USB 3.0 will be the same as USB 2.0 (standard), but the cable therein will be more, there are an additional four USB 2.0 channels compared to cable (a total of nine cable channels).

Compatibility
USB 3.0 compatible with USB 2.0, so USB 2.0 devices will still be used in USB 3.0 port and will work with USB 2.0 standard speed. But not vice versa, a USB 3.0 device cannot be installed on a USB 2.0 port.

Operating System Support
Windows Vista, Windows 7 and Linux already support USB 3.0, and Mac will soon follow. But for Windows XP until now there is no certainty whether there will be an update to this new interface.

LACK of USB 3.0

Cable Length
Maximum length of a USB 3.0 cable will be reduced to 3 feet (USB 2.0 up to 5 meters). While this can be overcome by adding a USB Hub.

Speed Limit
Not all devices can use a USB 3.0 full speed, such as magnetic hard disk is limited to the speed of rotation of the disk copies.

A little about CMD Command Prompt

The windows operating system user may be very familiar with the name CMD command prompt, which is a windows tool to run commands on windows OS in the text base, because there are times when the GUI version of the program is not as rich as a command line functions requires us to access the command prompt.

History of The First Computer Virus

First time computer viruses are created simultaneously with a computer. In 1949, one of the creators of computer, John von Newman, who created the Electronic Discrete Variable Automatic Computer (EDVAC), presented a paper entitled “Theory and Organization of Complicated Automata.” In his paper discussed the possibility of a program that can spread by it. Development of a computer virus subsequently occurred at AT & T Bell Laboratory, one computer laboratory in the world which has resulted in many things, such as language C and C + + . In this lab, circa 1960s, each time off the researchers to make a game with a program that can destroy the ability to fix itself and behind the opponent’s attacking position. In addition, the game program can reproduce itself automatically.

War of the program is called Core War, namely the winner is the owner of the program remains highest in a particular time interval. Well aware of the dangers of the program, especially if it is leaking out of the laboratory, each finished the game, the program has always been destroyed. Around the 1970s, Xerox introduced a program used to assist the smooth working. Program structure resembling a virus, but this program is to utilize as much time as possible and at the same time two tasks can be performed. In the 1980s, the war began with the virus in the world open up the exposure Fred Cohen, a researcher and assistant professor at the University of Cincinnati, Ohio. In his presentation, Fred also demonstrates a program of his creation, which is a virus that can spread quickly in a number of computers. While developing the virus, Indonesia has also started to hit the virus outbreak. This is the first computer virus to spread in Indonesia is also on 1988. Viruses are so appalling all computer users in Indonesia, then, are © Brain virus known as viral Pakistan.

Understanding Computer Viruses

The term computer virus is not foreign to the current computer user. In fact, about 12 years ago, this term has been recognized by the computer user community.

Virus found on a computer is just a regular program, as appropriate on other programs. But there are very fundamental differences on computer viruses and other programs.

  2. Placed outside track2 virus program that created the DOS (e.g. track 41)
  3. The size of the virus was made as small as possible so as not to attract suspicion.

The ability to conduct manipulations
Actually not too important routine manipulation. But this is often distracting. Normally this routine is made for:

  1. Create a display or a disturbing message on the screen
  2. Replacing the diskette volume label
  3. Damaging the structure of the disk, delete files
  4. Disrupt the working tools of I/O, such as keyboards and printers

The ability to obtain information
Namely the ability to obtain information about the structure of storage media such as the location of the original boot record, partition table layout, layout FAT3, the position of a file, and so forth.

The ability to check his existence
Prior to infiltrate a file, the virus checks for himself in that file with the search for an ID (identification) himself in that file. Files that have not been infected with a virus must not contain the ID of the virus concerned. This ability to prevent the infiltration of many times on a same file.
