YES & NO
No - You cannot actually increase the RAM or CPU of one machine by linking it to another.
BUT
Yes - You can simulate this by using methods so that the end result is the same.
The common way of doing this is called "Distributed Processing" where one or more computers are designed (or have software running on them to allow) to work together. They would share tasks or even check each others work.
The how it is done part of the question is dependent on how the solution is designed. By that it is meant that computers can be designed from the ground up for this purpose or normal off the shelf computers can be used this way by networking them together and then using software to control the processing.
Another older method is called "Parallel Processing" where two or more computers split tasks into smaller chuncks and work on each at the same time. This is slightly different in that they don't share hardware but instead share the problem.
What does the old meaning for hardware have to do with computers?
Computer hardware consists of the physical components of a computer; excluding all software and programming.
Computer hardware is your case, hard drive, motherboard, processor, RAM, optical drives, etc., etc..
256 x 8 ... u must of seen that online store or something and it may mean that there r 8 peaces of RAM sticks and have 256 MB (Maga Bytes) in each of them which is not really good RAM at all unless u can plug that much in ur computer which may do desent but u can get up to 16 GB (Gaga bytes) per RAM stick
Can you have three or more displays on one graphics card?
The out-of-the-box answer is No. Unfortunately, all those graphic cards that advertise they can have more then two monitors kinda lie. Unless you use whats called an Active Passive Display Adapter and your graphics card has DisplayPorts, you cannot have more then two monitors per graphics card. Even if you plug it in, it just won't work no matter what and you will only have two at a time displaying anything except a black screen. Once you plug in the adapter, you will be able to have an additional screen on the graphics card however this screen will remain black during BIOS and loading.
What is the meaning of voltage control device and current control device y they call like this?
In vcd, input voltage controls the output current.e.g.jfet
In ccd , input current controls the output current. e.g. bjt
It can probradly be that the headphones are old or not working anymore so i prefer you to buy another one and if it still not working there something from in your computer
What is the command to make the file Myfile.txt a hidden file?
A simple way is to right click on the myfile.txt, select Properties and put a check in the 'Hidden' checkbox.
Another way would be to: in the command window (Start > Run , type "cmd" in the box).
CD to the myfile.txt folder and then use this:
attrib +h myfile.txt
or
attrib +h "path to myfile.txt" (include the quotes)
attrib -h would remove the hidden setting

What works with one source statement at a time translating it to machine level instructions?
Are you asking about an "interpreter"? That's part of a computer language that reads a line of code and breaks it down into machine code.
The Interpreter works with one source statement at a time, reading it, translating itto machine-level instructions, executing the resulting binary instructions, and then moving on to the next source statement.
Almost no real interpreters generate any machine code, they simply interpret the source code and directly do what it says using machine code built into the interpreter when it was originally written.
Machine code is generated by compilers, to permit repeated execution without having to reload the compiler each time (as one must with an interpreter).
What is the color of pci slot?
Most are black, but they can be any color the manufacturer wishes to use. DFI motherboards often use colorful PCI and PCI-E slots.
What is hard format and soft format?
- hard sector formatting - sectors are separated and identified by physical notches or holes in the media that are detected optically, a counter register counts the pulses from the sensor and the number in this hardware register identifies the sector being read or written.
- soft sector formatting - sectors are separated and identified by coded address fields recorded on the media during formatting, as these address fields are created by the formatting software the sectors can be placed in any order (not just sequential as hard sector formatting does) around the tracks or skewed from track to track that might improve access time on a given system.
A system overclocks when the voltage is changed manually by the user. Due to this overclocking, there is a high risk for every component of the system, mostly, the processor.. The processor gets over heated soon and the system resets or throws errors..
In my point of view, its recommended not to change the voltage specification of the system..
What does could not write run key mean?
This refers to running the installation program that is loaded on your computer. You may have to reinstall software if this doesn't auto correct itself.
The HCF4046 integrated circuit is a phased locked loop control IC, typically this would be used in a switched mode power supply, however these are only ever needed where the load is frequency dependent and also drifts. In PC PSUs, a PWM IC is used instead to regulate power very precisely, such as a TL494.
In short, the 4046 would not be used in any computer equipment!
