What is a system clock function of a computer?

the system clock determines how fast the computer can process information. it is measured in operations per second. i believe 1GHz is equal to 10,000 processes per second? but im not sure. however, each thing you do on a computer may take multiple lines of code. for example, clicking the mouse may take 2 lines or so to execute.

Overclocking is the process of increasing the clock to a higher level so it can perform more operations per second

Differences between a computer and human brain?

Some differences between human beings and computers are:

  1. Brains are analogue; computers are digital
  2. Computers access information in memory by polling a memory address, brains search memories using cues
  3. The brain is a massively parallel machine; computers are modular and serial
  4. Processing speed is not fixed in the brain; there is no system clock
  5. Short-term memory is not like RAM
  6. Computers are hardware that runs software, there is no "mind software" running on brains
  7. Synapses are far more complex (electrochemical) than computer logic gates (electrical)
  8. Computers use processors and memory for different functions, there is no such distinction in the brain
  9. Computers are designed, built and are of fixed architecture, the brain is a self-organizing system
  10. Computers have no body, brains do

Why is a computer more efficient than a human being?

Who said that a computer is more efficient than a human being ? Can a computer reason, think, consider. These are some of the human qualities that a computer will never be able to achieve regardless of future technologies. This is in my humble opinion of course.

What is boot in a computer?

Booting is defined as: "The time when a computer's motherboard, Hard Drive, RAM, and other peripherals receive power from the distributor." During this time the computer's OS (Operating System [instructions for the computer]) are loaded into the RAM and several small diagnostics are run (mouse, keyboard, USB, monitor). Depending on your computer's available memory, Operating system, and number of boot files, this can take anywhere from 30 seconds to about two and a half seconds. An example is the Windows XP screen with the small, green scrolling bar at the bottom.

What should be used to indent and align text?

Indents

The distance between the text and the left and right edges of the pages defined left and right margins and indentation. Field, as you learn from the lesson, 13 are usually applied to an entire document or a greater part of it. For small fragments of text, such as lines and paragraphs, use indentation.

The easiest way to indent - use a horizontal line and a mouse. In order to derive the line (or hide it), click View -> Ruler. The numbers on the ruler indicate the distance from the left margin in inches. Fig. 10. 1 shows the range and variety of its labels, which are needed to determine the indentation, as well as various types of padding.

Indentations are used to separate paragraphs. To indent a paragraph, place the cursor anywhere within the selected paragraph. If you set the padding for a few paragraphs - select them (otherwise, the new padding will be installed for new paragraphs that you type, starting from the point of entry). Then drag the indent on the ruler to the desired position. As you drag the marker vertical dashed line passing through the document will show the new position of the indentation.

• To change the indent the first line of a paragraph, drag the First Line Indent to the desired position.

• To change the indentation of all lines of a paragraph except the first, drag the ledge to the desired position (and thus to a paragraph can apply the effect of "Orphans").

• To change the indentation of all lines of a paragraph, drag the Left Indent to the desired position.

• To change the indentation of the right edge of the paragraph, drag the Right Indent marker to the desired position.

You can quickly increase or decrease (1 / 2 inch) left margin of the current paragraph by clicking the Increase Indent Decrease Indent on the Formatting toolbar. The fastest to indent the first line of the paragraph - put the cursor at the beginning of the line and press the Tab key.

Setting indents using the Paragraph dialog box

Word allows you to set indents using the Paragraph dialog box. To do this, follow these steps.

1. Click Format -> Paragraph to open the Paragraph dialog box, then click on the counterfoil Indents and Spacing tab (Figure 10. 2).

2. In the Indents click on the arrow next to the text boxes on the left and the right to increase or decrease the indentation. To highlight the first line of a paragraph with an indent or to create a dangling line, click on the arrow text box, first line, then specify the indentation in the text box on. Area sample page shows how to look in the document the current settings.

3. Click OK. New installations will be applied to all the selected paragraphs, or to the new text.

Alignment - the formatting is a means in which the left and right edges of text lines are located along the relatively vertical lines. Word offers four types of alignment.

• Left - aligns the left edges of lines.

• Align Right - aligns the right edges of the rows.

• width - align both left and right edges of lines.

• Center - sets the center of each line between the left and right margins.

If you are using to change the alignment of the dialog box, select the paragraph, and then do the following.

1. Click Format -> Paragraph to open the Paragraph dialog box, and, if necessary, click on the counterfoil Indents and Spacing tab.

2. From the drop-down list, select the desired alignment.

3. Click OK.

Tool wrap automatically breaks each line of a paragraph, when it reaches the right margin. Word offers several ways to transfer control of lines. You can prevent a line break between the two words, so that these words will always be together in one line. These methods are particularly useful when changing the indentation or alignment, as this often changes the position of the transfer line.

By default, Word breaks the string into place a space or a hyphen. To prevent a line break, insert non-breaking space or a non-breaking hyphen instead of the usual. To insert non-breaking hyphen, press <Ctrl Shift - (hyphen)>. To insert non-breaking space, press <Ctrl Shift npo6en>.

You can use a possible transfer to specify where it is possible to divide the word if necessary. This is useful for long words, which are at the end of the line, because if the long word will be rescheduled for the following line at the end of the previous line will remain many gaps. Possible transfer will not be visible until until some words will not pass on the right margin. Then the transfer, and the next line goes only part of the word, which is beyond the hyphen. To insert a possible transfer, press <Ctrl - (port)>.

Finally, you can start a new line in the same paragraph, press <Shift Enter>.

What fundamental set of programs control the internal operations of computer hard ware?

The programs that controls and manages the basic operations of a computer's hardware are generally referred to as system software.

How can Defragmenter affect my computer?

The disk defragmenter puts fragmented files back together in an orderly manner to speed up data access, leading to faster opening of files and programs. So defragging is an important drive maintenance task. You can defrag manually with the Windows defragger or just get an automatic defragmemter like Diskeeper09.

What are the disadvantages of radioimmunoassay?

the health and safety risks posed by the use of radiation and the time and expense associated with maintaining a licensed radiation safety and disposal program.

What are millions of computers around the world connected by a network of networks?

The Internet, or the World Wide Web as it's called also, originally was used by academic researchers at universities across the country to more easily share data on studies or common areas of interest. DARPA (now ARPA, the US military's Advanced Research Project Agency) liked the idea of a web-like network that was self-healing if part of it was compromised. Data was re-routed if it couldn't make it from its point of origin to its destination in the most efficient manner.

So the answer is to the question is a WAN, a Wide Area Network (as opposed to a household router with three computers relying on it, a (Local)AN. The World Wide Web rides on the Internet, but generally a mechanism takes human-friendly domain names and converts them to a series of digits that for some reason computers like more when sending and receiving packets of data.

How can the use of the computers cause public safety problems?

This is a broad question, since it would include computer-related risks and the role of computers in improving or managing public safety. Here are some examples including both of these areas:

  • Using computers and related devices while driving is a safety hazard.
  • Computer devices are not to be used during the take-off or landing of aircraft, since that could affect the instruments.
  • Excessive use of computers can cause personal injury, including carpal-tunnel syndrome, carpal-dorsal syndrome, and increase the risk of developing myopia (particularly in children).
  • Computer navigation devices can increase automobile accidents if they are not updated. Drivers may rely on them too much and drive off of cliffs.
  • Vehicle engine computers can malfunction, cause acceleration problems, and may increase accidents.
  • Police officers may rely on computer equipment too much and not rely on their skills and training. For instance, what if they only watch for weapons when their dash console computer says someone is armed and dangerous?
  • Computer-operated traffic controls don't work without electricity.
  • Computer-operated traffic controls can malfunction. That could put cars in the path of other cars if all lights are green, or it could cause drivers to run lights because the light is stuck.
  • Personal computers can make stalking and some criminal activities easier.

How do I email a picture to a computer?
