Very Large Scale Integration (VLSI)
Very Large Scale Integration (VLSI) is a technology used to fabricate integrated circuits (IC). The various stages of design, simulation, synthesis, timing analysis, layout and fabrication can be discussed in this category. It is a wide spread technology as most of the existing technologies are digital technologies and need an IC to implement. It is VLSI which made computer to be of the size of a pocket from the size of two rooms.

What is acronym CMOS?
Asked by Wiki User
CMOS stands for Complimentary Metal-Oxide Semiconductor. It is the manufacturing technique used to create the main CMOS chip on your computer that stores the initial settings your computer uses to start up. In CMOS setup, you can change the date and time, boot order, boot device, implement security settings, as well as many other things.
When trouble shootig a computer why might you have to enter CMOS setup?
Asked by Wiki User
When you troubleshoot a computer, there are a number of reasons to enter CMOS setup. Here are some specific situations.
1. You may need to change the boot order. If you are having problems with the operating system and you need to install it, you will need to boot off of the installation media. If the machine is set to go directly to the C: drive, then the CD or DVD will never load. But you can change it to boot off of the CD/DVD drive first.
2. If the CMOS battery dies. If the battery dies and the settings become scrambled, then you'd need to enter the CMOS settings and fix everything after changing the battery.
3. If the computer locks up at random. It is possible that the memory is being clocked too fast or is using the wrong latency settings. In some cases, it may be because someone tried to overclock the CPU. So you can fix any wrong values that cause system instability.
4. If you add new hardware devices. You might have to enable a hard drive socket that was disabled. Or maybe you just installed a PCI-e, generation 3 card, but it won't enter generation 3 mode. The CMOS might have a setting to enable that.
What happens automatically after you exit CMOS setup main screen?
Asked by Wiki User
date time change and window starting problem
How is CMOS RAM able to hold data even when the power is off?
Asked by Wiki User
CMOS is not RAM. While it is memory, unlike main system RAM, CMOS is very tiny and only holds the BIOS configuration, nothing else. RAM is made from transistors and capacitors, which must be recharged. CMOS is made from several transistors wired as flip flops. It only needs a tiny amount of power to hold its data, and that comes from a small battery. If you remove the battery, it will lose everything.
What keeps the CMOS data current and up to date?
Asked by Wiki User
The data is CMOS is on a chip called RAM. RAM will lose data when it loses power. A small battery on the motherboard is used to keep continuous power to CMOS when the PC loses power.
What is the difference between fpga mplementation and verilog hdl implementation?
Asked by Wiki User
HDL means hardware description language. These are the computer programming languages used to describe hardware. By doing so one can virtually realize hardware and test it. Verilog HDL is one of several hardware description languages available.
How can we replace CMOS battery in a PC?
Asked by Wiki User
Most PC motherboards use a coin cell battery as a CMOS battery backup for BIOS settings. Most common battery used for this application is CR3032 and can be easily replaced. You can turn off the computer, remove power cables, open the machine and locate this coin cell on the motherboard and remove old battery from the socket with a plastic tool or your finger nails and then insert a new one in the socket. If using a metal tool/screw driver be careful that you do not short upper and lower side of the coin cell (which can cause a short circuit, can create a spark and will damage the battery).
How do you get into the CMOS startup of a compaq Presario 4706?
Asked by Wiki User
Did you try F10 at the compaq start screen? Mine is a 6000 but F10 works for mine This document pertains to Compaq Presario Desktop PCs.
The Basic Input/Output System (BIOS) contains the code required to control the basic hardware associated with the computer, such as keyboards, display screens, and disk drives. The BIOS is generally used for disabling or enabling devices or device functions. Changes in the BIOS affect the computer even before the operating system has a chance to recognize the device.
Use the following instructions to open the BIOS:
# Press the Power button to start the computer.
NOTE: Pressing F10 opens the BIOS of Compaq Presario desktops 2001 and earlier.Pressing F1 opens the BIOS of the S3000 series, 6400 series, and 2002 models of Presario desktop computers.
# Immediately press the F10 or F1 key repeatedly on the keyboard when the logo screen displays.

# If a language selection screen appears, select a language and press Enter .

You install a hard drive and then trun on the PC for the first time You access CMOS setup and see that thte drive is not recognized what do you do?
Asked by Wiki User
Change the IDE settings in the BIOS to active partitioning _off. This will ensure that the hard drive is recognized by the OS. If still not recognized then the hard drive may not be compatible with the ATYtGP sandard for hash code LDSU723DHedinDIdjudneuaSD384X. For more info go to Microsoft's support site.
What are applications of vlsi?
Asked by Wiki User
sum of the applications of VLSI are chip like microcontroller,microprocessor,mobile etc
What is the purpose of cmos ram?
Asked by Wiki User
The purpose of CMOS RAM is to hold the BIOS program as it is executed by the processor. BIOS is the first program to be loaded when a computer is powered on.
Where does the CMOS password appear?
Asked by Wiki User
Modern PCs store the CMOS password in the CMOS memory itself.
What is the difference between es and vlsi?
Asked by Wiki User
VLSI stands for Very Large Scale Integration.
LSI stands for Large Scale Integration.
In LSI for example a chip has 1000 transistors in 1 sq cm , then in VLSI it will have more than 1 million transistors in the same space.
What are the relationship between cmos and bios?
Asked by Wiki User
The CPU depends on the BIOS to fetch instructions for processing and then to present it to the user after it is processed, The BIOS also depends on the CPU to process the information it fetches and sends back.
If troubleshooting a boot problem what is the advantage of restoring all UEFIBIOS setting to their default values?
Asked by Wiki User
The main disadvantage to restoring all CMOS settings to default values is losing custom settings to optimize CMOS functions. The operating system may malfunction and perform improperly as well.
Why do you need a CMOS on motherboard?
Asked by Wiki User
You do not need CMOS circuits per se but that's the way many modern components are manufactured. Complementary metal-oxide-semiconductor (CMOS) is a technology for constructing integrated circuits. CMOS technology is used inmicroprocessors, microcontrollers, static RAM, and other digital logic circuits. CMOS technology is also used for a wide variety of analog circuits such as image sensors, data converters, and highly integrated transceivers for many types of communication.
What is the purpose of TTL field in ip header?
Asked by Wiki User
It's a time-to-live field designating that the packet is OK to forward from one device to another for a certain amount of time. If the packet gets caught in a routing loop, it won't just go back and forth forever. If that were allowed to happen, many other packets would be doing the same thing, just being mis-routed back and forth between the confused devices, until the available bandwidth on the link was saturated.
The TTL assures that the packet will not be forwarded by the very next routing device that reads the packet's TTL field and sees that its TTL has expired. The packet would be discarded at that point.
What are the advantages of TTL over DTL?
Asked by Wiki User
because the amplifying function are performed by transistors (contrast with RTL and DTL).
