What does processing refer to?

Processing refers to a computer system handling a task. When you click something on the screen or go to open/run a program it processes your action by opening said program(s).

What can computer users do to reduce the likelihood of their personal privacy being violated?

  • 1. Use a password manager 2. Disable GPS and Wi-Fi on your mobile device until you need them3. Read the access privileges for apps carefully, and make good choices 4. Guard your date of birth and telephone number 5. Make yourself more difficult to find on social media 6. Keep your work and personal presences separate 7. Encrypt your connection
  • 8. Collective action 9. Clean browsers before and after browsing from any one of these software Privazer or Soft Cleaner. Always detach internet connection when it is not needed,even it broadband or WiFi.
  • 10. Always visit on SSL encrypted (HTTPS) Website.

What is the average size of a WAV song file?

Answer: The WAV audio file format is limited to files that do not exceed 4 GB in size. This is due of its use of a 32-bit unsigned integer to record the file size header. This is still equivalent to about 6 hours of CD-quality stereo audio.

Where can one find a barebone laptop online?

There are many online technology websites that provide reviews on a wide variety of laptops. Some websites one can visit to find reviews on a barebones laptop include Toms Hardware, RJ Tech and Notebook Check.

Why don't some songs burn onto CD?

Probably because they are in the wrong format. If you are using iTunes, to burn a CD the song must be in MP3 or an MP4 format, or else it won't work. Or sometimes, the song has a glitch and is just like that. If you downloaded the song off the internet, then that happens a lot with those files. You could try and use another program to burn them, such as Windows Media Player.

What are the 3 internal components of a computer?

Many things are inside the case of a computer, and some will just depend on your computer, but the hardware all computers have are:

The CPU, or central processing unit: This is often called the "brain" of your computer, for it is what makes all the other pieces of the computer do whatever you want it to do. It is one of the most expensive and important parts of a computer.

The CPU cooler: This piece cools down your CPU, since it gets very hot from the work it is given.

The motherboard: this is where all of the components of a computer are connected to. It transfers what the CPU wants something to do to that certain piece to execute the task. It would probably be something like the body in general or the nervous system in a human.

The RAM, or random access memory: This is where all your processes are stored. It is like the short term memory in humans, while you are using it, you remember it, but once you delete it, it is gone from your memory.

The power supply: To put it simply, it is what supplies the power for your computer. All it does is convert the unusable electricity from your home wall socket into a usable form of electricity and spreads it throughout your computer.

The next pieces are not necessary, but are in most computers:

The hard drive: This is the long term memory, where your files are saved onto, unless you delete it. All of your downloads, programs, files, documents, etc. are saved onto here.

The graphics card: Commonly mistaken as the GPU, or graphics processing unit, is what creates the images that you see on your monitor. It converts the code given to it from the CPU into the pictures that you see on your screen today. The GPU, is simply a part of the graphics card, the part that does most of the converting.

The optical drive: This is the cd/dvd/blu-ray player in your computer.

Now, for the optional items:

A sound card: Most motherboards these days have integrated sound built in to them, but if you are an audiophile or need very high quality music for some other reason, you will need a sound card. Most computers do not usually come with one, however.

Fans: To cool down your system and increase air flow.

What features do multimedia computers offer?

Multimedia computers are so named because they are designed to offer optimal experience using many different medias. Most computers today are considered multimedia, even smartphones in some cases. As long as the device has the ability and functionality to play games, watch video, take pictures, listen to audio, and store and process files for these medias they can be considered multimedia.

How did networking start?

I retrieve this from http://www.tech-faq.com/who-invented-the-internet.html I hope this answers your question.

Despite what he may have said, Al Gore did not invent the Internet. The Internet was invented in the United States during the late 1950s to the 1970s by a group of researchers and scientists at the newly formed Advanced Research Projects Agency (ARPA) after the former Soviet Union launched Sputnik. Realizing that the United States had suffered a great technological blow by allowing the USSR to hold the first successful satellite launch, ARPA set out to create a brand new technology unlike anything that had ever been done before; and the Internet was the result of their hard work.

Although there were many people working for ARPA on the Internet project, there are five individuals who can really be credited with actually creating the Internet. Among them was J. C. R. Licklider, the head of the Information Processing Technology Office at ARPA. In his position, he thought up the idea of the Internet itself as a way of potentially unifying humans from around the United States (and the world) through a universal network.

Because Licklider's previous experience was not in actual computer programming, however, he had to recruit others in order to help create the Internet for ARPA. The obvious choice was Lawrence Roberts. Roberts went on to lead the team which would eventually develop ARPANET (the early precursor to the Internet) in 1967. He was the scientist to finally utilize the proposed method of packet switching first created by Leonard Kleinrock. The Internet still uses packet switching as its primary way of transferring data.

After several years of work, a computer at the University of California, Los Angeles, became the first computer to connect to the Internet. In time, three more computers would be connected to the Internet in 1969, leading to the start of the Internet revolution.

Despite the massive success that Lawrence Roberts had received while working at ARPA, he promptly quit his position in 1973 in order to form the world's first commercial network, known at that time as Telenet. However, in his place, he assigned Robert Kahn and Vinton Cerf to continue working on the Internet at ARPA. Together, Robert Kahn and Vinton Cerf worked to modify the original method of packet switching pioneered by Roberts and Kleinrock and eventually created what is now known as the protocols. It was at this point when ARPANET was finally changed to the more easily pronounced Internet.

What are different types of CPU organizations?

thay are ...1.One bus org

2.two bus org

3. 3 bus org

What is computer binary numbering system?

We use a sytem that uses a base or 10, that is the numbers, 0 to 9, then we add a 1 to make 10 and start again 11,12,13 etc. The binary system uses a base of 2, like a switch on or off. so we get ;

Binary Decimal

0 0

1 1 now we have run out of numbers so we add another 1 to the left;

10 2

11 3 which is made up of a 2 and a 3; next we add another 1 to the left

and so on.

100 4

101 5

110 6

111 7 which is made up of a 4, a 2 and a 1

Thats it just keep going, every time we add a new 1 to hte left, its worth twice the value of the 1 to its right, its just like us using units, tens, hundreds thousands.

What size of a space would a small computer fit in?

It typically depends on the brand, but with the advances in technology now you could fit a laptop or iPad in a 2' x 2' space easily and still have plenty of room left over.

Which devices are used to capture data?

Automatic Data Capture means capturing data at source where it happens in machine readable form for example a point-of-sale terminal (POS) with a bar code reader.

The most common automatic data capture devices are given below:

1) Bar Code Reader (BCR):A bar code is made up of a sequence of bars of different widths printed on products. Bar codes are read into the computer using a wand or a fixed scanner at POS terminals. 2) Optical Mark Recognition (OMR):An optical mark reader reads marks made by pencil on a printed form into the computer. OMR systems are used by examination boards to collect the answers to multiple choice examinations and to purchase lottery tickets. 3) Magnetic INK Character Recognition (MICR)At the bottoms of cheques, account number and cheque numbers are printed in spcial kind of ink called magnetic inck. The MICR are used to read these characters. 4) Sensors:Sensors can be used to measure physical quantities such as temperature, light and pressure. The measurements can then be stored for later use (data logging) or used to control devices such as heaters or fans (computer control).

Why do computers have both immediate access store and backing store?

Computers work with immediate storage called RAM (Random Access Memory) and longer term storage called ROM.

When a Computer runs an Application, the Computer needs to remember stuff to run the application, such as what the program looks like. This is Graphics Memory, and one example of RAM.

I encourage you to look at the Wikipedia page for RAM (included in related links), this may provide more insight.

Is the toshiba computer the best in the world?

This question requires more of a personal opinion. The benefits of getting a Toshiba laptop is that there are more programs tailored especially for windows. But Mac computers are also well known for not having any viruses and their great quality and customer service. I hope this answers your question.

What is the process of data retrieval?

Data retrieval is made many times easier if you have a backup of your information stored on a different hard drive. If not, a hard drive can be detached and placed in a different machine to be scanned for any remaining code and data on it.

What do you need to be a computer literate?

An extensive knowledge of computers, including maintenance, operating systems (particularly Linux) programming languages, computer hardware and ofcourse emoticons I am not very computer literate so i am sure others can extend this answer indefinitely...

Apparently the computer language OXML is still ahead of its time.... hope this helps ;)

The primary function of a parity bit in a programming a programmable controller or computer is to?

A parity bit is a primitive checksum-like tool, used to verify the integrity of a group of data bits. For example, some memories support a parity bit to cover an 8-, 16- or 32-bit bus, and on serial data lines, parity bits (typically covering 8 data bits) are sometimes used to help detect transmission errors.

A parity bit is, as the name suggests, a single bit, and is only effective with a number of simple errors, while a great number of other possible errors will slip through a parity-based integrity check undetected.

Stronger integrity checks use a cyclic redundancy check (CRC) or more sophisticated methods, such as SHA-2 and others. Priority bits still have their place where those more sophisticated methods are unsuitable or unappealing due to their cost or processing requirements; priority bits are very cheap to implement and validate in hardware, and can at least provide some level of integrity where the alternative might have been no integrity checks at all.

Are computers good for us?

Computers has many points which are bad and good, depends on how you look at them.

For one- computers have made the world so much easyer, communication has improved to the point where your cell phone has the power of a computer running windows 2000.

Without computers, your life would be very boring, infact you would not even have read this.

No fancy cars

no ipods

and for all you south African users no mxit.

The world would be a place you could not imagin

What are some major advantages of using an online brokerage rather than a stockbroker?

Buying stock online will typically be cheaper than buying through a broker. Also in some cases online purchasing is closer to real time in the market compared to calling your broker and having them process a transaction.
