Individuals may be drawn to VLSI technology for a combination of these reasons, depending on their interests, skills, and career goals. It's a dynamic field that plays a crucial role in shaping the future of electronic devices and systems.

Verilog was created in 1984.

Current date and time

After taking apart the laptop (see instructions at

http://www.takeitapart.net/forum/index.php/topic,5.0.html) I found there is a CMOS battery under the keyboard, but it is soldered to the motherboard. This doesn't make it useful as a reset. I did not find a jumper or any other reset switch internal to the laptop. My research seems to suggest that holding the power button for 30 seconds is supposed to reset the CMOS. Unfortunately, that did not help in my case, but may for yours.

What is this question really asking? If you are asking if you will find a 7400 IC in a phone, the answer is most likely no. If you are asking is there logic gates such as AND, OR, XOR, NOT gates in a mobile phone then the answer is yes, thousands if not millions of them. Where are they used in the phone? Everywhere from the CPU to the display of the screen, power management, you name it, they are there.

BTW: You should know that the CPU is nothing more than a collection of logic gates. A CPU may seem to work by magic, however I can assure you that there is nothing magic going on in a CPU.

CMOS is a small component cluster on a computer motherboard which hold a very small amount of simple information. It has a large button battery which supplies the needed power to preform one of its main functions: Keep date and time. It also holds vital system settings.

Basicly, It is a small memory componant, but users can not store data on it aside from system boot settings.

Its is the button battery that stores the BIOS settings for your computer.

Below code can implement OR gate in VHDL.

The code is written in behavioral model.

Cmos logic family, because it has no resistors attached who consume active power.

I don't have experience with that exact model, but I have disassembled and repaired a few Sony laptops. From my experience the CMOS battery is usually located towards the back (if you were facing the screen in a normal situation) under the keyboard. Before starting you should have a good #0 and #00 Phillips screwdriver with a magnetized tip. To access the keyboard screws, you must first remove the top panel. Usually it's one screw on the side, then slide the panel to the side and lift up. Be careful of the ribbon cables for the speakers and power button. You should be able to see the keyboard screws. You may have to remove some shielding to get to the battery. Usually the "=>" marked screws. If the battery is not a button cell type like the typical CR2032, look for a two wire lead (red/black). Some cooling fan wires look similar to the CMOS battery leads. The pigtail type batteries are usually stuck to the main-board with foam double sided tape or Velcro The next step is trying to find the replacement battery without paying an arm and a leg.

There is no specific disadvantage it is economically unreliable for very small lab trials, research and study purpose.

To know about the advantages of TTL logic family, one should have a basic idea about RTL, DTL etc. Diode logic (DL) uses diodes to implement logical functions like AND and OR. But the disadvantage is that it can not perform NOT operation. As AND and OR are not complete functions by themselves, they can not perform several logic functions without NOT. Hence, there was a need for some device which can perform a NOT function as diodes can not. That device is a transistor. Then came the DTL which uses a transistor along with diodes. As a transistor can act as an inverter, NAND (NOT-AND) & NOR (NOT-OR) operations can be performed. But this logic uses several diodes which will slow down its operation. Due to the delay offered by them, the logic levels may sometimes change i. e. 0 t0 1 or 1 to 0. Then came TTL. This logic uses a multi emitter transistor, a transistor with many emitter terminals. As every emitter is nothing but a diode, this logic eliminates the use of all diodes. This is the major advantage. As transistor becomes ON and OFF much rapidly than a diode, switching time will be faster. TTL, or Transistor-transistor logic replaced resistor-transistor logic, and used much less power. The TTL family is very fast and reliable, and newer faster, less power-consuming, etc. types are always being developed. = In TTL (Transistor-Transistor Logic), think that the device using this technology is made from several transistors. Another advantage is that many more chips employ this technology.

VLSI is Very Large System Integration

Today, instead of using vacuum tubes (which were used in electronic products a few decades ago), transistors are used. the biggest (but not the only) advantage of the transistors is the size - instead of having a vacuum tube that id 1-2 cm, a single transistor is around 40 nm (nano meter) - 25000000 times smaller!!!!

it means that one can create a very complex system, with tens of thousands of transistor, on a single chip that is in the size of 1x1 cm. In other words, one can integrate many complex modules in his system.

The problem is that when a human being is designing such a complicated system, there are many mistakes because of the system's complexity. Therefore, it takes a very careful process of checks and verifications when designing such a system

Standard TTL (which stands for Transistor-Transistor Logic) circuits operate on a 5V power supply. The typical level for a logical "0" is between 0V and 0.8V, and the typical level for a logal "1" is somewhere between 2.2V and 5V. Typically, a value little lower than Vcc (power source voltage) is used; in case of a 5V supply, this is usually around 4.5V, but TTL devices are built to withstand full Vcc as input, just in case.

Logic gates are transistor circuits, normally arranged on a silicon base and encapsulated inside an integrated circuit. (chip).

Using several transistors wired together, their inputs can be arranged such that, for given inputs, the output will only change state for certain conditions.

The transistor switches are in either of two states, 'on' and 'off'. These are logic states 1 & 0 (one or zero), hence binary.

The logic uses Boolean algebra.

NOT, means it is 'not on', = OFF. This is abbreviated in the descriptions as the letter 'N'

A simple AND gate, means that the output is at level zero until both inputs have a level 1 voltage on them.

A NAND gate is a 'Not And' gate. The result is reversed. The output is always at logic level 1 until both inputs also have a level 1 also.

A slot on the motherboard intended to hold the CMOS battery.

A logical family is a person who is logical to want you say or other word it is a family want consider your choice and think of it for you if it will destroy any future plans

A logical family also reason and give life guiders responses

to draw a conclusion

a logical family is a family that consider future chices so it can be good it future plans

a ogical family is a resonable group of people living other one roof in love inspite of all the battles the face.

Yes. While the computer is booting up, keep pressing the escape key until it appears.
