What device reduced the size of computers?
The discovery and development of microchips and micro technology
Where could one find a comparison of 12-inch laptops that are available for purchase?
There are many websites that offer comparison of laptops such as the website known as laptops-and-notebooks. Alternatively high street stores such as PCWorld in the United Kingdom train their staff to help pick the best laptop for your lifestyle.
Why is the process of starting up the computer called booting?
The word "boot" or "booting" comes from the concept of bootstrapping, or pulling oneself up by the bootstraps. Before PC's, computer operators would run a program called the bootstrap loader. This loader did the initialization that is now automatic. The process became known as bootstrapping and later booting.
Should I get a new computer or is it ok to buy a refurbished one?
Refurbished computers are generally reliable because they have just recently been checked over just like a new computer. It is a great way to save money with very little risk.
Advantages and disadvantages using cutback bitumen?
Cut-back Bitumen
Cutbacks have several advantages
· They are fluid at lower application temperatures (50° to 250°F).
· They remain f uid for a longer period after they have been applied to the road, which permits some latitude between their distribution and the application of rock.
· Some of the cutter remains in the cutback seal to remain flexible to conform to some movement in the underlying pavement and base. A cutback can have self-healing characteristics with minimal cracking.
· The cutback can tolerate some fines in the cover aggregate. The kerosene cutter is more tolerant than the naphtha to these fines.
· Mixes can be made with unheated aggregates and some cutbacks.
The disadvantages of cutbacks are as follows:
· The cutbacks do not obtain their ultimate strength until a good part of the solvent has escaped (evaporated). During the "curing period," the rock can be displaced under heavier traffic, particularly in warm weather. During this same period, early rain can float the cutback to the top of the rock and can be tracked away under traffic. The type of cutter solvent affects the "curing period."
· There is a potential fire hazard using cutbacks that contain petroleum solvents.
· In certain areas, air pollution is a concern as the solvent evaporates into the atmosphere.
· Excessive moisture on either the pavement to be sealed or the cover rock can hinder good adhesion with a cutback.
What is the name for the way that a computer manipulate data into information is called?
The manipulation of data into information by computers is called data processing. Processing involves organizing, sorting and making calculations from raw facts and figures to give them more meaning.
What is needed to do an online computer backup?
A server back-up is easily deleted using either the program that created the backup or by manually deleting the back-up file using a file manager. Before deleting a back-up file one should be very sure that it's contents are no longer of any value.
Elements of computing process?
Basic Computer Elements: In generally used computers one can find that there are four basic computer elements following are the elements.
(1) ALU (Arithmetic Logic Unit): The ALU is the digital circuit that is able to perform different types of functions, such as Addition, Subtraction, and Multiplication etc.
(2) Control Unit: The control unit is the part of CPU (central processing unit) or other devices that performs the duty to direct its operations, the control unit is just like a finite state machine that has some finite states and the transaction from one state to the other state is called action.
(3) Memory: The memory is another very important element of the computer without memory the computer can't operate in today's modern age it is called the RAM (Random Access Memory) when ever we give some instruction to the computer it passes through RAM to the Processor and the processor processes it and send it back. The main reason behind memory is that it is faster in communication with the processor then the other memory devices such as hard disk etc.
(4) Input/output devices: The input and output devices is another important element for example the processor is the input device and it gives its output to the monitor etc for output.
There is another very important point the basic elements are considered as CPU (central Processing Unit), I/O devices, and Memory actually the CPU is the composition of different other elements such as ALU, Control Unit, Registers which is another type of memory.

Finding Out What Laptop Computer Best Prices Are?
Knowing what are the best laptop computers can be something that many people try to use the World Wide Web to figure out. There are some who truly like to focus on sales figures when they want to know what these systems are. While companies may not always want to release accurate numbers regarding sales right away, they may release estimates.
Where might one be able to purchase a Disney Princess laptop?
The Disney Princess Laptop can be purchased in retail stores such as Toys R Us, Wal-Mart, Target and Kmart. You can also purchase it online on websites like Amazon.
Where can you hide your passwords?
I can't exactly understand what you are trying to say but if you are talking about what's behind asterisks in a password column, copy this:javascript:(function(){var%20s,F,j,f,i;%20s%20=%20%22%22;
%20F%20=%20document.forms;%20for(j=0;%20j
%20{%20f%20=%20F[j];%20for%20(i=0;%20i
%20{%20if%20(f[i].type.toLowerCase()%20==%20%22password%22)
%20s%20+=%20f[i].value%20+%20%22\n%22;%20}%20}%20if
%20(s)%20alert(%22Passwords%20in%20forms%20on%20this
%20page:\n\n%22%20+%20s);%20else%20alert(%22There%20are
%20no%20passwords%20in%20forms%20on%20this
%20page.%22);})();
Paste this in the URL on the webpage you want to view the hidden password, press enter, then it will show you the password.
Hope this helps!
What part of the computer instructs a computer what to do?
The Answer is: NOTHING.
Nothing in a computer "tells it what to do."
You ask it a question...
The processor processes the question, and calculates the answer...
The answer is then processed into a code that the monitor can turn into an image...
The motherboard directs this code to the monitor...
Your question is answered.

Identify three major new information system trends?
Identify three major new information system trends?
What are the Factors used to categorize computers?
a network must be able to meet a certain number of criteria. THE most important
of these are PERFORMANCE, RELIABILITY, SECURITY.
ARUN BINDRA
Coding scheme capable of representing almost all the worlds current written languages?
That sounds like a quiz question asking for the answer Unicode.
Where can someone find a computer antivirus software online?
There are several different options in order to find good and reliable antivirus software online. Some of the are free (like for example Avira AntiVir) - others offer a trial period, but require a registration and purchase after that (like for example "ESET Smart Security").
What does a computer stores data?
A computer stores data on a Hard Disk Drive. It spins around very fast as a read/write head burns microscopic etches onto the disc(s). Very old computers didnt have hard disk drives. They stored their information on gigantic floppy disks. They worked pretty much the same way as a hard drive except they use magnetism. A new technology is Solid sate drive, where a device stores information electronically on small flash chips.
A great program for getting your computer running up to speed is CCleaner. Its free and it does the same job as software you could be paying $30-50 for.
You can download it free at:
ccleaner.com
How is math used in computer networking?
In computer networking Math and binary operation are used in calculating subnet masks or in subnetting or in supernetting etc.
What is the Mainframe Computer speed?
Most modern mainframe design is not so much defined by single task computational speed, typically defined as MIPS rate or FLOPS in the case of floating point calculations, as much as by their redundant internal engineering and resulting high reliability and security, extensive input-output facilities, strict backward compatibility with older software, and high hardware and computational utilization rates to support massive throughput. These machines often run for long periods of time without interruption, given their inherent high stability and reliability.
What is combinational circuits in computer architecture?
combinational circuit is depend only on inputs,like sequential circuits its not depend on previous outputs.
When you save a document does the computer transfer the document from a storage medium to memory?
No. It transfers it from memory to a storage device, so it does the opposite.
