An output device is a computer device which receives the signal from the Micro Processors & gives the result to computer user. Computer Printer, Monitor and Speaker are examples of output device.

Depends on how the phone is being used. If you are using the phone to get internet from (tethering) it would be an input device. However, if you are putting pictures or music on the phone it would be an output device.

A computer functions by integrating several systems together. First it needs a CPU or central processing unit. This is the brain of the computer. It also needs memory chips so it can retain information and external storage media to store information for later retrieval. Of course, it also needs a power supply because a computer won't function without electricity!

CCleaner is good for a Windows PC because it removes cookies, trackers and temporary files that may be harmful to your computer and slow it down. It allows your computer to run faster and more efficiently.

A display device is anything that will put images on a screen to see what input and actions a user would ultimately need visual confirmation. The most common display is the default monitor. By its term means that by default any monitor should work if installed on a CPU prior to turning the power on. The screen has dials that can make the display seem blank and sometimes adjustments must be made to the display itself. A television can be used on most modern systems. The way to determine what display you may use is to simply find the VGA or similar type of connection on the back of the tower. The different styles are easily defined by the number of pins.

Computer viruses, or malicious sections of code intended to damage a computer system, spread in several ways. True viruses are self-replicating, meaning that there is a piece of code causing them to copy and distribute themselves. By:

Posing as something useful (known as a Trojan horse) ie a download, a gift from a friend, etc. Current scam is a 'gift card' or an 'ecard' email that tries to run a malicious script when opened. Because you gave the computer the command to open the file, the virus has an easy path in. By:

Emailing itself - will search for anything fitting an email address xyz.com and then send itself there. By:

Infecting a 'clean' file without the owner's knowledge - lots of viruses can be spread this way, by people downloading files from safe sources that have been hacked by people intent on spreading viruses. By:

Using networks - if one computer on a Local Area network or wireless network is infected, this type of virus will infect every computer on that network if not blocked by a suitable firewall. By:

Using removable media - usually, disks, USB drives, external hard drives, floppies, CDs etc. are not checked by the virus scanner when they are inserted, so a virus hiding on one can get onto the computer unquestioned. Most viruses are spread by 'freaks' or people who hack computers and write viruses because they are essentially twisted people who enjoy causing damage. Some are more targeted, ie stealing information or money, or destroying particular programs. All of them have the potential to do great damage, and there are more ways to spread them than mentioned above.;

Control Unit is an hardware eye of computer.

Well, as you might already know that CPU(Central Processor Unit) is termed as brain of computer.

CPU consists of three parts as follows

1. ALU(Arithmetic and Logic Unit)

2. Memory

3. CU(Control Unit)

Job of control unit is to monitor all activities and make sure that everybody is doing what they are supposed to do.

Add RAM!

Up to the limit that your motherboard can support.

Open the case, remove the old, smaller memory card, plug in a larger memory card that is compatible with the OLD memory card.

You add more RAM.

The motherboard on your computer has sockets to take RAM. There are different types of RAM so you need to get the right version. There is a limit to the size of the RAM that your Motherboard can support, and that varies from machine to machine.

If you don't know the details take it to a computer shop and get them to upgrade it for you. They'll be able to tell you what type it takes and how much you can put in.
