What is the use of a USB HUB?

Before seeing the use of the USB hub, let us know what a USB hub is. Older computers have very low number of USB ports, say around two. It might be necessary to plug in more devices in to the computer than the number of the USB ports available. Hence we need a device or an external method by which we can increase the number of USB ports. Here is where the USB hub comes in to play.
A USB hub is nothing but, like an extension plug, for the USB port ion the computer. The USB hub consists of multiple ports. The USB hub is connected to the USB port of the computer and then the other end of the hub can be used to connect other external devices. The other end of the USB hub may contain more then one socket for increasing the number of devices that can be plugged in to the computer.
Thus the use of the USB hub is simple. It provides multiple sockets to connect multiple devices in to a single USB port. It is just like a multi pin socket. 
USB hubs may be of USB 1.1 version or USB 2.0 version. The…

What is meant by cache Memory ?

Cache memory is also called temporary memory. This kind of temporary memory is used in all forms of computing to increase the speed of processing.
Why does Cache increase the processing speed?
Say a CPU is processing information. It would be better to have the information it requires to process it with it to increase the speed of processing, than to retrieve it from the hard-disk every time it is needed as retrieving it from the hard disk take more time (This increases the time of processing).
Caching may be Memory caching or disk caching.
Memory caching is similar to the one explained earlier. It is the cache memory which resides in the CPU, which stores the information temporarily for processing. This increases the speed of processing.
In memory caching, the cache that is built into the CPU itself is called Level 1 caching. It is also called L1 caching. Some CPU’s have another chip installed near it to increase cache. This is called Level2 caching. It is also called L2 caching. Some CPU’…

USB drive not copying or reading - Troubleshooting tips

When a USB drive is recognized, but if you are not able to read from it or write to it, there might be some hardware problems. Here is the to do list for tackling the problem
1. If your USB device is not recognized, remove it and put it back. If it is still not recognized, either there is a fault with the USB or the Computer or you do not have such permissions for inserting removable media. Or the drivers are not working properly. Try installing the USB drivers.
2. If the USB drive (pen drive or any memory card) is detected, but if you are not able to read from it or write to it, then you will have to remove any extending wires and try inserting the pen drive in to the USB port directly.
3. If it still does not work, there might be some hardware problems, so you have to contact your vendor.

What is Firmware ?

Firmware is also called as Read –Only- Memory. Firmware usually comes as ROM chips .Firmware is 
Non–volatile. By non-volatility it means that the chip does not need any power source to retain its contents. This is opposing to RAM (Random Access Memory) which loses its contents once the power source is cut-off.
Firmwares are also writable. A very famous writable firmware is the BIOS (Binary Input/output System).
The BIOS stores information pertaining to how the Computer boots. It does not loose its settings when you switch off a computer.
Firmwares are currently used in almost all the High-tech gadgets like Cell phones, PDA, Computers, GPS systems and so on.

What is a live CD ?

A live CD is a normal, but bootable CD, which you can use to boot a new Operating system, without installing it in your computer.A live CD is also called LiveDistros.
Many Linux operating systems come in live CD’s. Many of these Operating systems are quite useful since they come packed with a lot of good utilities like word-processing, Powerful browsers. Hence through Live CD’s these operating systems can be booted without installing them in the hard-disk in the first place. This kind of booting does not affect the operating system present in the hard-disk. This feature helps in the easy use of live CD’s in any computer without installing it.
When the system Boots it normally processes the instructions in the BIOS [Binary input/output system].
The BIOS by default boots the operating system from the hard disk and hence .it’s settings have to be changed to boot from the CD or removable disc such as pen drives and memory card.

How to free a lot of RAM in a computer

A simple trick to save a lot of RAM [Random Access Memory]
Say open an application say your web browser. Say you have opened Internet explorer. Have it maximized.
Then open task manager and then look at the Memory usage field of the Internet explorer process (iexplore.exe).
Now just minimize [don’t minimize using the win + m keyword] internet explorer and then you will be able to see that, in the task manager the memory usage value has gone down by a huge value from 34000 to around 2000.
So if you are going to use multiple applications, minimizing the applications which are not in use will help save a lot of RAM.
This occurs because, windows is a multitasking operating system. When the user minimizes an application, the operating system thinks that the application which is minimized, will not be used by the user for a while and hence it frees the RAM used by the application to a considerable extent. This trick will also work in almost all multitasking operating systems. So, do not hesitate…
