Computers

30minutes for a child 1 hour for adults if your doing homework or work as long as you need to with 10 minute breaks every half hour.

It depends on the kind of computer you have. In desktop PCs, you would need to open up the protective box (while the computer was off, of course) and access the RAM straight on the motherboard. There it can just be snapped off and replaced with RAM of the same settings for that motherboard (i.e., SDR or DDR, appropriate clocking speed range for the motherboard). In laptops the concept is similar, but gaining access to the RAM is very brand-specific. Often times easy access is only available for additional RAM. I would recommend looking at the instructions that came with your laptop.

The computer's Random Access Memory (RAM) temporarily stores data and programs while your computer is on.

Obviously having the best hardware is going to make your computer faster but there are somethings you can do to help speed up start up.

First Go to the RUN menu (you can do this by hitting Windows Key + R)

Type in - MSCONFIG - and hit enter

Go To Start Up tab and hit the button that says DISABLE ALL

Next if you have more than one core CPU go to BOOT and select to poot from 2 cpus or as many as you have.

This will speed your boot time.

I have found that most players play the file extensions MPEG2 and DVD, although there is still the problem with some home players not playing either ( I still haven't figured out why ) while still other home players play them with no problem.

Fragmentation is when files are stored in small pieces scattered all over the storage medium. In spinning disk technology the read head has to move around to find and read each piece. This fragmentation makes the reading of files take longer. When the data is defragmented it is stored all in a row and the read head can find the data much faster.

Note that flash memory technology has no moving parts and doesn't suffer from fragmentation slow down. In most cases the data is actually purposefully fragmented for wear leveling, increasing the durability of each read/write element.

The IMB personal computer was invented in november 21 1984

They might, it depends on the creators of those computers and what they will make them do next. Computers are already doing a lot of things now that if the world didn't have any power people would be in trouble.

An IP address is the unique identifier assigned to any personal computer connected to the internet.

If the computer is stuck in a situation where it no longer accepts commands and doesn't shut down as requested, you should give it amble time so that any potential pending operation can complete or fail gracefully. If the situation doesn't change, you should consider forcefully removing power.

In a desktop PC, this is easily accomplished by unplugging the mains cable from the wall socket. In a laptop or other portable device, you may also need to remove the battery.

Note this is an emergency measure. Forcefully removing power in this manner can cause data loss or even damage to hardware. Modern systems are designed to cope with unexpected power outages, however. You'll need to allow extra time when re-starting, as the operating system will (hopefully) scan the hard drive or flash memory drives for errors caused by the sudden power outage, and attempt repair.

Amazon.com always has some great prices. Wal-Mart is usually cheap as well. The best time to buy cheap is right before Christmas. You can get some great sales then!

The case, motherboard, and power supply must all be the same form factor. Obviously the motherboard and the case would have to be the same or the motherboard would never fit in the case. Then the power supply must not only fit in the case, but have the same connectors as the motherboard. Otherwise it won't work.

To do very complex math problems that would have taken months for a person to calculate. Computers basically all work by math - binary code is 1 and 0 - and everything we have done with computers since then is based on mathematical programming!

The company Lenovo sells products related to personal technology. They mainly sell PC's, or personal computers. However, they also sell tablets, servers, and workstations.

First you have to save the photo. Depending on the email program, this means right click on the image and chose "save as" or using the menu option "copy attachment". Now you have the image on your computer, for example in my documents and ca resize it as you do with any regular image file (see the linked article for an answer to that).

A: it is not actually a tool but a ground wire connected to the earth ground which is connected to the chassis

The best way to protect your system against ESD is to use a ground bracelet together with a ground mat. Consider a ground bracelet essential equipment when working on a computer.

It is a method of doing some particular thing.

in Psychology, it describes solving problem in a step by step procedure that guarantees a result. The opposite of algorithym is heuristic.

TCP (Transmission Control Protocol) is considered to be a 'reliable' protocol for the transport of data. This is because it uses a applies a conversation mechanism that involves establishing a connection (a process known as 'hand-shaking') before sending the data and waiting for the receiving computer to reply.

If the receiving computer didn't get the complete data (e.g. it didn't arrive or it was corrupted) then it will request that the sending computer retransmits the data.

UDP (User Datagram Protocol) is considered to be an 'unreliable' protocol because it does not bother with the hand-shaking or the error checking. Data is transmitted and is assumed to arrive at the other end. It's up to the Application Layer (not the Transport Layer) on the receiving computer to sort out the datagrams that arrive and check that they're not corrupted.

IF the receiving computer is going to request missing or damaged UDP packets then it's up to the application to do so, not the Transport layer.
