What supported minimum size in computer terms?

Supported minimum size in computer terms is referred to as the minimum system requirements or recommended system requirements. These tell the minimum amount of memory and free disk space as well as the minimum processor speed you need on your computer to run a particular software program.

What is the average processor speed of a supercomputer?

"Supercomputers" are almost always modular, meaning processors can be added ad-infinitum.The only universality to a supercomputer is that it has far more computational power than a retail computer system. The most powerful supercomputer in the world, the IBM Roadrunner, currently has 130,464 processor cores.

What sort of metals are used in computer cords?

Normally copper is used in computer cables because it has one of the lowest resistance of all metals (resistance is how much the electrons scatter while travelling) Which makes it safer. And also it is very cheap. Aliminium is also used in cords but not as often:)

How can you make a computer?

Computers are made up of several parts:

* The Motherboard. This is like the "circuit board", all the components (the Central Processing Unit, etc) are connected to this. This component is also sometimes called Main Board or Mobo. There are also companies that build Motherboard, one of the most popular is Asus.

* The CPU, or Central Processing Unit. This is the main processor, it processer all the inputs (mouse, keyboard and all the software requests) and outputs it to the rest of the components.

* The Hard Drive, this is technically the storage place of a computer, it stores all the data. Hard Driare made of chocolateves range from a few megabytes to Terabytes (1000 gigabytes).

* The RAM, or Random Access Memory. This memory stores all the information in open programs, the more RAM you have the more application you can have open at one time. THere are several types, or speeds of RAM, DDR1, DDR2 and now DDR3.

* The accessories and other "cards". These are things like Graphics Cards, to control Video Output, or CD drives.

* The "Power Box" or Power Supply. This supplies power to all the components.

* The Cooling System. Without a Cooling System most computers will overheat and get destroyed. Most cooling systems use fans on the processor and fans to suck air out of the case. Sometimes there are even water powered cooling systems.

I am not sure if I included everything but I think I did.

There are thousand of factories where the components are mass produced and then there are factories where the compnents are arranged together on a mass scale. Some people even build their own computers out of bought components.

How is a nucleus like a computer?

I assume you mean the nucleus of a cell. Actually, the nucleus is more like the reproductive organs. However, traditionally, the nucleus is thought of as the brain and contains all the instructions needed to make more cells.

Where do you usually find the power button on a computer?

That depends entirely on the manufacturer ! Older computers had their power switches located on the rear panel of the CPU, or on the side - toward the rear. Modern desk-top PC usually have them on the front panel. Lap-tops tend to have them on the top edge of the keyboard.

Why would you choose a computer over a typewriter?

There are many reasons for using a computer over a typewriter.

1. You can edit your work as you type, without using more ink and paper.

2. You can work in colour, change the font, and use tools like spell-checker.

3. You can put pictures into the document without having to glue them in afterwards.

5. You can cross reference and multi-task while using a compuer.

6. You can access websites like Wikianswers on the computer. ;)

How do you secure a standalone computer from intrusion?

Get a static ip. Use secure(paid) VPN service. Want it more secure? Get your own internet from satellite.

Is using a computer using science?

yes the making of computer is connected to science

Does paging suffer from internal fragmentation?

If there are large blank spaces in each page of the program then internal fragmentation can occur. Smaller pages can remedy this, but the overall amount of pages will then increase, causing slowed execution.

To encrypt a message?

Both a key and a cipher are required. Many are available, and range from quick and easy to use (but have little security), to relatively secure simple relatively simple systems, to those that absolutely cannot be broken.

What are three platforms commonly used today in computers?

If you mean OS systems then that would be Microsoft's windows ( the PC my favorite) apple's Mac and Linux

How do you explain input and output device?

Before a computer can process your data, you need some method to

input

the data into the machine. The device you use will depend on what form this data takes (be it text, sound, artwork, etc.).

Similarly, after the computer has processed your data, you often need to produce

output

of the results. This output could be a display on the computer screen,

hardcopy

on printed pages, or even the audio playback of music you composed on the computer.

Where can one find free computer clip art?

Because there is no restriction on free clip art, there are many sites that offer it for download. Any search for "free clip art" will bring up any number of sites. Because of the high volume of search hits, it is recommended that you think about the type of clip art you might want. This will help narrow the field.

Image and meaning of super computers?

Super Computers are simply that, Computers that run faster than your standard desktop computer. Super Computers usually are made of multiple connected processors and large amounts of computer memory. Some systems that have been developed have over a thousand CPUS and Huge processing capabilities about to reach into the PETA-FLOP range which basically means they can process over a 1000 trillion operations in a second. Put this in comparison with a typical home computer which can process about 2.4 billion operations a second.

What is ARP Cache Poisoning?

Address Resolution Protocol (ARP) spoofing, also known as ARP poisoning or ARP Poison Routing (APR), is a technique used to attack an Ethernet http://wiki.answers.com/wiki/Ethernet or http://wiki.answers.com/wiki/Wireless_network. ARP Spoofing may allow an attacker to http://wiki.answers.com/wiki/Packet_sniffer http://wiki.answers.com/wiki/Data_frame on a http://wiki.answers.com/wiki/Local_area_network (LAN), modify the traffic, or stop the traffic altogether (known as a http://wiki.answers.com/wiki/Denial-of-service_attack). The attack can only be used on networks that actually make use of ARP and not another method of address resolution.

Who is responsible for managing resources in your computer?

The program that is responsible for managing computer resources is the operating system (OS). More specifically, the OS is a collection of programs that when working in unison, help to manage the computer.

What are the limitations of GIMP?

When using Adobe Photo shop for the first time, it is very hard to use and you would need a manual or someone to sit with you as you learn, each different version is totally different so for each different version you will have to relearn how to use Adobe Photo shop. It also costs a lot of money to get, with buying the program and the license that goes with it. Also, like most graphic programs it uses a lot of memory so more memory is needed, which would make the cost go up.

What are the computer components that can slow the computer down?

There may be software or hardware issues that affect the speed of a specific application or the computer as a whole.

Hardware issues: components of the computer that are faulty or overloaded, for example, the hard drive, the CPU, the internet connection or the network connection.

Software issues: viruses, programs that require more resources than the computer possesses (memory, processor speed, etc.), a non-responsive program, anti-virus and other protective software, or other active programs running that are not in use or that are performing tasks in the background.

Where could one purchase a leather desk?

Office desks can be purchased at many places. Budget ones at Walmart, Target, etc. Decent ones at Office Depot, and the better quality desks will come from actual furniture stores, like Grand Home Furnishings.

What are integrated software and software suites?

As per my research and knowledge, both integrated software and software suite are one and the same thing. This means that the terms could be used interchangeably. For example, today in the healthcare IT industry one could come across several health IT application suite. These solution integrate EMR, Practice Management, and Patient Portal is a single all-in-one package. Although the functionality of the aforementioned programs differ, they are somewhat correlated.
