.**********************************************************************Common logic levelsLogic level: TTL, CMOS, LVTTL, ECL, PECL, gtl;rs232, RS422, LVDS, etc.The logic level of TTL and CMOS can be divided into four categories according to typical voltage: 5V series (5V TTL and 5V CMOS), 3.3V series, 2.5V series and 1.8V series.The 5V TTL and 5V

What is TTL level, what is CMOS level, their difference(1) TTL High Level 3.6 ~ 5 V, low 0 V ~ 2.4 VCMOS-level VCC can reach 12 VThe output height of the CMOS circuit is about 0.9vcc, while that of the output low is about0.1vcc.The input that is not used by the CMOS circuit cannot be left blank, which may cause logical confusion.The input end not used by the TTL

1 IntroductionImage sensor is a device that converts optical signals into electrical signals, which is widely used in digital TV and visual communication market. The new concept of solid State imaging and a one-dimensional CCD (charge-coupled device charge-coupled device) model were proposed in the late 60, when the charge was found to be transferred through a semiconductor potential well in the American Bell face room. By the early 90, CCD technology has been relatively hot, and has been widely

　　A Understanding CMOS Settings How do you get into the CMOS settings? When you turn on the screen, there is always a hint that says "press Del to enter the CMOS settings" We press the DEL key on the keyboard at this time. Now you see the interface of the CMOS settings. Different computers may have different int

Difference between bios and CMOSDuring daily operations and maintenance of the computer, you can often hear about BIOS settings and CMOS settings. Many people often confuse bios and CMOS settings. This article mainly describes how to distinguish BIOS settings from CMOS settings in terms of basic concepts. What is bios? The so-called BIOS is actually the basic inp

Many netizens have asked about the main difference between CCD and CMOS. For the time being, let's take a look at the two different types of image photosensitive elements with the same function through a simple comparison.Both CCD and CMOS basically convert light to electricity using the silicon photodiode. The principle of this conversion is similar to the "Solar Cell" effect of the "Solar Energy" electron

Magic CMOS helps you easily manipulate CMOS content Do you think CMOS is a very magical place! You are not the engine room in the configuration of each machine's CMOS and worry about, you have not been blocked by the network lock CD-ROM, so you can not copy the pain of the content, so many, have you ever thought about

and restore the image. Finally, let's talk about CMOS: CMOS (Complementary Metal-oxide semiconductor) is a complementary metal oxide semiconductor, which is a semiconductor in microprocessor, flash memory, and specific purpose integrated circuits (ASIC ).TechnologyIs absolutely important. Both CMOS and CCD are semiconductors that can be used to feel light change

Text/SuperVirusI wonder if you have written some prank or little "virus" experiences? I used to play this thing before and never thought about how to contribute and earn living expenses. However, after reading several articles, I feel that no one has discussed this in detail. In this issue, I am going to make an ugly look, hey. The pen name of the original "web technical expert" is too exaggerated. The experts want to laugh at me, so we should keep a low profile and call it the name on the blog.

CMOS is a special type of RAM (it loses its stored content when power is lost)BIOS is software, is the program!CMOS is the chip, is the hardware!In fact we are through the BIOS of this program, to set the parameters of the COMs.COMs is a chip, inherited on the motherboard, which holds important switch machine parameters, and the preservation of the need for electricity to maintain the amount,So each motherb

first, the system can be started, you can enter the CMOS, and did not set the power-on password, you can soft erase the CMOS, and restore to the default settings. (1) Enter the CMOS settings, and transfer to the original default settings Boot Press del, enter CMOS settings, in the

BIOS (Basic input/output System) is the primary input/output systems. It is actually a set of programs that are solidified into computers, for computers Provides the lowest level, the most direct hardware control. To be precise, the BIOS is a "translator" or interface (though it is only a program) between the hardware and the software program. , responsible for the immediate requirements of the hardware, and the implementation of hardware requirements according to the software. Programmers can

Introduction to CMOS password cracking"CMOS Password" is generally referred to as "BIOS password" or "boot password", mainly to prevent others from using their own computers, set a barrier, (this document is used only when the password is forgotten and cannot be used to intrude into others' systems or other malicious purposes)There are many methods to crack the "CMOS
