How do you format computer if the CD rom is not on computer?

go to "computer" then right click on "system c " then right click on it and go to "format" but you will lose your windows you are running your computer on and everything else

You just bought a used Trinitron computer monitor When you hooked it up it says monitor is in power save mode How do you turn that off so you can use it?

It should turn off automatically if you plug it into your computer and turn the computer on. If it doesn't, something is wrong. First thing to check is the plug that plugs into the computer for bent pins. Also check the other end of the cable that plugs into the back of the monitor. If the pins are not bent then you will likely need to take it to a shop for repair or replacement.

What software runs the hardware connected to a system?

The pieces software that runs the hardware in your computer are called Drivers. These either come built in to your Operating System, or they come from another source such as the Internet or an Install CD/DVD.

Screen in computer is an input?

A computer screen is only an input device if it works with Touch Screen Technology else its output only

Do plug and play devices require drivers?

If you are talking about the TV plug and plays, then no.

If you are talking about a microphone or a controller, then yes. Plug and plays are usually USB based, and all USB's require drivers.

How do you use Ethernet port as USB port?

Well, you may know that USB ports can be used for similar and same purposes as Ethernet. Really, the only hardware need is a converter.

Another Answer

The Ethernet ports on a computer system are supported by standard TCP/IP protocol layers, while the USB ports are supported by a serial standard. These are totally different hardware channels. I've never seen such an interface offered, but that certainly doesn't mean it doesn't exist.

Does the CPU supply provide power to a CPU fan or a case fan?

Neither, The CPU is the Central Processing Unit, it only processes information and bits of data the computer sends thru it. The motherboard supplies power to the case fan AND the CPU fan, which is supplied power from the PSU (power supply unit)

What is difference between a tower and a desktop?

A tower is the part of the computer which all the main devices are located. The tower is where you first turn your computer on. A desktop is the same thing, a desktop consists of a Tower, Monitor, Keyboard, Speakers, and a Mouse.

Can you use a brand new laptop hard drive instead of a brand new desktop hard drive when building a computer?

If they are both SATA, then you can. Laptop hard drives usually require less power but in the same time they do not perform as well as desktop counterparts. If you have SSD that is laptop size (2.5') you will even see improvement. 2.5 SSDs are used for both desktops and laptops.

How can you upgrade the integrated graphics on an Acer Aspire E650?

Depending on what the bios has set the memory to be used from the onboard graphics, you can tell it to use more ram, ie change it from 64 - 128mb. But in doing this, your detracting from the physical ram. Eg you have 256mb ram at the moment, using the onboard graphics, (64mb), means you only have 192Mb, which is nothing in todays world of computing. So if you tell it to use 128mb, you will only have 128mb ram. :(

The best thing to do, imo, is to purchase a dedicated graphics card for this machine. With it being a media centre pc, I would opt for the largest graphics card you could afford. Nothing less than a 256mb would be my preferred option.

Hope this helps

be safe

If wireless laptop is not near an access point is a router needed?

If the access point has a wireless interface and if your laptop supports the wireless network type, no you do not need a router.

<><><><><>

If the laptop is not near enough to an access point, it will not be able to connect. The router is immaterial.

Write VPN technologies supported by Windows 2000?

Microsoft Windows 2000-based virtual private networking (VPN) supports Internet-industry standards technology to provide customers with an open interoperable VPN solution. Microsoft is committed to IETF (Internet Engineering Task Force) standards-track-based technology such as Internet Protocol Security (IPSec) and Layer 2 Tunneling Protocol (L2TP) as well as Point-to-Point Tunneling Protocol (PPTP)a proven published informational RFC that is supported in multiple interoperable third-party products.

  • PPTP provides simple-to-use, lower-cost VPN security. Unlike IPSec technology, PPTP is compatible with Network Address Translators (NAT) and supports both multi-protocol and multicast environments. It also combines standard user password authentication with strong encryption without requiring the complexity and expense of public key infrastructure (PKI).

  • IPSec provides advanced security for VPN but was not designed to address critical remote access requirements such as User Authentication and Address Assignment. In addition, it does not support multi-protocol or multicast (including some routing protocols). It is applicable primarily to IP-only, unicast-only situations.

  • L2TP in combination with IPSec is the onlystandards-track technology that addresses these remote access VPN requirements while leveraging IPSec for encryption. L2TP currently retains the same IETF standards-track status as IPSec.

  • Third-party IPSec-only implementations that do not use L2TP with IPSec are using non-standard proprietary technologies that can lock customers into closed solutions.

How can you check the CPU usage on a Windows 98 machine?

go to start>programs>acc.>system tools>system monitor.

There is also a free tool available at www.analogx.com, called netstat I think, that will give you your CPU usage and monitor the traffic in or out of your machine. They also have a great memory manager that keeps your ram from being locked up by Windows, and a bunch of other neat stuff too. I've used a number of their programs for years, and find that they're fun, useful and reliable. Good Luck. Oh..there whois will tell you in about 2 seconds if a domain name is available, and who owns it and where to find them in another few seconds if it's taken. Several useful tools there.

What is the importance of magnitude comparator?

Generally, magnitude comparators are digital circuits (IC's) which have two ports which accept, and latch two 8 or 16 bit binary numbers and have three single bit outputs: "Greater than, less than, and equal."

I have used these personally in several digital control systems.

I guess the "importance" is twofold. First, as you can use a single IC you simplify the hardware, but more importantly, for certain operations, they can be invaluable.

One simple use would be comparing the output of a free running digital counter to some fixed number. This fixed number, if derived from user adjustable binary hex switches, would allow control based on some adjustable terminal count. For instance, if the counter also fed into a D to A converter, and use the magnitude comparator to compare the two numbers, you now have a user adjustable ramp which can further be used with analog comparators to trigger many sorts of analog systems and also acts as a digital divider. One could create a temperature control for example using a sensor as one input but calculated in the digital domain, possibly with some microcomputer to make decisions.

I once used a very similar setup using two daisy-chained magnitude comparators in a telemetry system where the comparators monitored a counter which counted digital telemetry pulses and thus was the "memory of the number of plses and were used as a trigger for a setpoint alarm or maximum allowable user adjusted limit. As mentioned above, they can aslo be used to make a digital divider. For instance, using a free-running counter as one comparator input, and user switches as the other, you will get an "Equal to" signal for every x counts / y user input count. Very simple way to divide counts by any amount.

It's not so much "what's the importance" as that fully depends on the application, but rather the versatility and all the clever things one can use them for. I've designed more complex uses for them but my lack of recall of the details would not add to this answer but I did do some pretty cool, very specialized things which would have been difficult dto do without using the magnitude comparators. Only your imagination limits the cool things you can uyse them for.

Basically, Analog circuits like op-amps compare strictly in the analog domain. Magnitude comparators allow comparing purly in the digital domain. Combining the digital, D-to-A converters, and op-amps allows doing both simultaneously, if needed by the aplication.
