Computer Hardware

Generally, powering up isn't as much of a problem, although certain peripheral equipment may not be identified during startup if they aren't already on when the computer tries to find them. Just put everything on a single shut-off switch and that problem should be solved. As for the shutdown process, certain operating systems leave files in strange "states" during operation and if the computer does not go through an orderly shut down the files will not be updated properly and will be corrupted next time your computer attempts to read them.

For removable media the above answer is true. If the hardware is a peripheral accessory device (scanner, printer, etc) the only risk is corrupting the operating system (typically & unfortunately Windows) drivers which could (but unlikely) have adverse and unpredictable results. The damage or dysfunction which could occur to the actual hardware are always described in the documentation which came with the device.

there are many types of processors. if you have double 2.1 it's quite good for usual work and normal gaming. middle Vista computer is Duo 2.0 GHz

• Defragging fixes the spaces left behind on your hard drive and makes it run smoother. For example, every time you save something to your hard drive it is put at a certain address so your computer can find it later. If you then delete that data, it leaves an empty space on the hard drive where the data used to be. What defragging does is to close all the spaces and move all the data together, so that your computer can find it better. You should defrag about once a month.
• No, that's defragging the whole hard disk and even then that's not what basic defragging does. Defragging the REGISTRY does not involve the entire hard drive, but just the system registry. It essentially consolidates it when keys are deleted or altered. As far as a noticeable difference, you will not see one.

  Defragging the HARD DISK on the other hand involves consolidating fragments. When data is saved to a hard disk, it will saved scattered sometimes. The data from one file could be in fragments all over the hard disk. Imagine reading a book where the paragraphs that would be on one page are scattered at random intervals. This would take a lot longer to read with all the jumping around. When you defrag the HARD DRIVE, those fragments are brought together to decrease read time. Hence the term, "defragment". So basically, you can have all the spaces you want between the data and still have a minuscule percentage of fragmentation. Fragmentation is caused from writing, not deleting.

  What the original contributor described above is file consolidation or a "space" defrag which is not standard and is usually found as a supplemental option with third-party defrag applications such as O & O. It too can have benefits, but it is not what defragging means and certainly not the REGISTRY as you were inquiring about.

Sound Card

A sound card is an expansion card which is used to send and recieve the sound signals and installed in a PCI slot of the motherboard.

Graphics Card

Graphics cards are the video cards which are used to produce the images you see on a monitor screen and it is installed on the motherboard as an extra component and used to graphical data with a high quality colour display and clear appearance.

Input, output, PROCESS, and Storage

A keyboard is an input-output unit that is supported by the operating system. The functions supported depend on the design and usefulness of the keyboard.

Typically, a keyboard supports alpha-numeric keystrokes. In addition, some keyboards also include a numeric keypad with special keys indicating addition and subtraction.

Most keyboards also contain up to 12 function keys, each with a special purpose, depending on the operating system and other software application that is in use by the keyboard operator.

Some keyboards also include a mouse-like feature, sometimes called a 'pencil eraser'.

Depending on software, keystroke combinations can also invoke special actions.

Output to a keyboard may be limited to feedback sounds or lights.

All operating systems interact with hardware.

They act as symbols to allow the visitor an easier and smoother browsing experience.

gigahertz is the processing speed of your CPU(eg. 1.8GHz,2.8Ghz etc).It's the speed at which your processor runs. Gigabytes is the unit in which data(any data)in your RAM,HardDisk,Memory card or any other storage device can be stored is measured.simply,Its the unit to measure the data storage capacity.Eg- 2GB RAM,160GB hard disk etc..

The MICR (Magnetic Ink Character Recognition) code has 9 digits and are also used to identify the bank-branch for cheque clearing and online transaction processes.

You can find MICR or IFSC codes of all branches across Indian at www.indiancodes.org

Its quite faster too.

Most computers have several ports, which may or may not be enabled. There are two serial, or 'com' ports, which transfer data to and from the Central Processor Unit a single bit at a time, and one parallel, or printer port, which transfers data eight bits at a time. Most modern computers have at least two Universal Serial Bus ports, which are a high speed port for operating modern peripheral devices, such as scanners, printers, external drives, and such.

There are several options to finding affordable, replacement laptop batteries. Online sites like eBay or Amazon offer a wide variety at low prices. Also, brick and mortar stores like Batteries Plus or Radio Shack will probably have what need as well.

without the CPU a computer would not be able to process any data. a CPU is the logical part of the computer which actually performs the calculation which is actually done in the ALU (arithmetic logic unit) part of the processor.

A jumper is closed (on) if the cover is in place, connecting the two pins that make up the jumper; a jumper is open (off) if the cover is not in place.

Yes.

There is no definitive answer to this question, but there is research to draw upon.

The safest way to shut down a computer is to use the operating system to properly shut it down. If you use Windows OS then you would go to your start button, click it, and go into <Shut Down>. For there you can choose Shut Down, Restart, Etc. These methods will save any data that you have not saved yet, close programs that are open, and properly shut the computer down.

Click on the icon of the USB drive.

Press Command I

A window will open. You can see the present name of the drive.

Select the name and change it to what you want. There may be a requirement for a simple name, so try to keep it short and with no special characters. Spaces are allowed.

You can also paste an image to be used as the icon in this pane.

Find an image for the icon. Click on it and press Command I. You will see a little image in the upper left corner. Click it until there is a blue edge around the little image. Press Command C. Click the little image in the USB drive pane. Press Command V. Some images do not have a preview image that can be copied. If a standard JPEG image is shown, select a different image to copy.

Typically changes in the BIOS are not stored on any file, but on the BIOS chip itself. This is why it is expressly important to back it up ( if supported ) when changing or flashing ( updating ) your BIOS

The main purpose of input devices is to allow users to input data, commands, and instructions into a computer system.

Input devices are used to interact with and control computer systems. They allow users to provide input in various forms, such as text, images, sound, and motion, among others. The input devices translate the user's input into a digital format that the computer can process and interpret.

Examples of common input devices include:

Keyboard: used to input text and commands

Mouse: used to navigate and select items on the screen

Touchpad: used as an alternative to a mouse on laptops and other mobile devices

Touchscreen: used to interact with graphical user interfaces (GUIs) through touch

Scanner: used to input images and text into digital format

Microphone: used to input sound and voice commands

Camera: used to input images and video

Joystick: used to control games and simulations

Gamepad: used to control games on consoles and PCs

Motion sensor: used to input motion-based commands and gestures

Overall, input devices are essential for enabling users to interact with and control computer systems, and they are critical for a wide range of applications, including communication, entertainment, education, and business.

Technically it's neither as it's just a shell that houses the devices. However, if you just mean the computer as a whole, then it is of course both because it's made up of input and output devices.

In the grand scheme of things it could be called an output device. Also in the same train of thought it could also be called an input device depending on how you look at the overall picture of how it is going to be used.
