What is computer system upgrading?

There are various things you can do to upgrade (improve) your computer. One of the easiest (and you'll see a difference) is to add more memory (RAM).

What provides internet access and members only faeture?

An internet service provider, or ISP, provides internet. Once you set up a personal internet connection, you can set specific membership requirements.

What is the abacus computer?

Yes, it was an early mechanical computer. It is regarded as the first computer, made over 5000 years ago. An abacus is not like a modern computer. People think of a computer as an electronic, programmable device that can store, retrieve, and process data. There were many computing devices prior to the electronic computer that had processing capabilities. They were mechanical devices and are computers. There are many different kinds of computing devices and an abacus is one of them.

What is hybird computer?

Hybrid computers are computers that comprise features of analog computers and digital computers. The digital component normally serves as the controller and provides logical operations, while the analog component normally serves as a solver of differential equations. In general, analog computers are extraordinarily fast, since they can solve most complex equations at the rate at which a signal traverses the circuit, which is generally an appreciable fraction of the speed of light. On the other hand, the precision of analog computers is not good; they are limited to three, or at most, four digits of precision. Digital computers can be built to take the solution of equations to almost unlimited precision, but quite slowly compared to analog computers. Generally, complex equations are approximated using iterative numerical methods which take huge numbers of iterations, depending on how good the initial "guess" at the final value is and how much precision is desired. (This initial guess is known as the numerical seed for the iterative process.) For many real-time operations, the speed of such digital calculations is too slow to be of much use (e.g., for very high frequency phased array radars or for weather calculations), but the precision of an analogcomputer is insufficient. Hybrid computers can be used to obtain a very good but relatively imprecise 'seed' value, using an analog computer front-end, which is then fed into a digital computer iterative process to achieve the final desired degree of precision. With a three or four digit, highly accurate numerical seed, the total digital computation time necessary to reach the desired precision is dramatically reduced, since many fewer iterations are required. Consider that the nervous system in animals is a form of hybrid computer. Signals pass across the synapses from one nerve cell to the next as discrete (digital) packets of chemicals, which are then summed within the nerve cell in an analog fashion by building an electro-chemical potential until its threshold is reached, whereupon it discharges and sends out a series of digital packets to the next nerve cell. The advantages are at least threefold: noise within the system is minimized (and tends not to be additive), no common grounding system is required, and there is minimal degradation of the signal even if there are substantial differences in activity of the cells along a path (only the signal delays tend to vary). The individual nerve cells are analogous to analog computers; the synapses are analogous to digital computers. Note that hybrid computers should be distinguished from hybrid systems. The latter may be no more than a digital computer equipped with an Analog-to-digital converter at the input and/or a Digital-to-analog converter at the output, to convert analog signals for ordinary digital signal processing, and conversely, e.g., for driving physical control systems, such as servomechanisms.

How does one remove a Trojan virus from one's computer?

There are many ways one can remove a trojan virus from one's computer. One can remove a trojan virus from their computer by downloading a virus removal software such as Sophos.

What are the two modes of the Windows NT 2000 and XP architecture?

The Windows XP Architecture uses both Kernel Mode and User Mode. The kernel mode is the layer of the operating system's code that is responsible for handling such fundamental operating system items as virtual memory and scheduling which applications will run at any given time. User mode is where your actual program runs and is controlled by components of the kernel. For example, the kernel is responsible for allocating the memory that an application uses.

How do you unlock characters in ssf2 demo vo7?

You unlock more characters in ssf2 dem vo7 byhacking it. You can only unlock two characters. Those characters are vegeta and black mage. You can unlock vegeta by palying as goku 100 times. Then it will go on the challenger approaching screen. Beat him and then you will have the saiyan prince Vegeta.

Someone who makes computer games?

It depends what they do to make computer games. There are many different jobs in the game industry. Such as programmers, 3D modelers, texture artists, concept artists, etc. Even writers if the game has a storyline to it. But most of these could simply be called "game developers", if you're not being too specific.

Can a computer be haunted?

If your computer starts doing "crazy things," it can either be two things:

A Virus Or Yup, it's haunted. To tell which of these it is, ask yourself this: Do I have a virus protection on my computer? If yes you have one, IT'S HAUNTED!!!!

Example: My computer gets frozen, then the mouse moves all over the place clicking on things, it stops for three seconds then the computer turns OFF!!!

HAUNTED!!! HAUNTED I SAY!!!

When is the use of STP cabling appropriate?

Here is one example. One of my networking students at the Cisco Academy worked at the local Coca-Cola bottling company. He told us that some of the cabling passed near some heavy machinery, and that the interference of the machines would have been too much for UTP to handle, so they used STP instead, at least in some cases.

What are two different ways to upgrade a computer?

People usually upgrade their computers by either buying hardware (new parts) or software (new programs). Different people will tell you different ways to upgrade your computer. If you want to upgrade your computer for office work, you may just need a newer operating system (ex Windows Vista). If you want to upgrade your computer for gaming or running performance programs, then you may need to upgrade your video card, RAM modules, and hardrive space. You can either install these components yourself, or pay to have an official worker from a store come do it for you.

Why use a computer for a databases?

A Word document is specifically text, in an application purposed to the writing, editing and formating of text.

A database can be used to categorize both numbers and text in ways that can then be operated upon to correalte relations and associations.
Searching for similar values, from numbers, to addresses, for example, and producing a report showing just those entries that fit the search parameters.


Also- Databases can be set up to have one input of information modified or acted upon by other information in an automated way.
For example, inputing a price in one field might automatically place the sales tax on that number in an separate field, without your inputing anything but the initial formula when you first created that filed.




Ergo, Word is a word processor for the purpose of composing text.
A Database is specifically for organizing, correlating, and manipulating information.

Is a notebook computer small?

A personal computer is simply a term. A computer for personal use, not industrial/commericial use.

A personal computer does not specifiy any type of computer in general.

The normal and popular specifications for types of computers are as follows:

Notebook (general laptop, most used for word processing on the go)

Netbook (strictly made for internet and social networking)

Desktop (the do it all machine, mostly browsing and gaming)

Net-top (less powerful desktop made for word processing and internet)

All-in-One (PC in which all components form one machine; less cords, and more space)

In order of size: Desktop > Net-top > All-in-One > Notebook > Netbook

A- Explain the difference between data and information?

Data is the knowledge in the raw form.It may be usable or may not.But a data becomes information when it comes to use.

Ex: My knowledege about computer is in data format in my brain.But when I am using these data to help you, it becomes info for you.

Hope I could explain that well.

What are the components that make up the system unit?

A system unit is a case that contains electronic components of the computer used to process data.

The most common components are inside a system unit are:

The processor

The memory

Adapter cards e.g. sound card, modern card, video card, network card.

Ports

Drive bays

Power supply

More Information:

Motherboard: The main circuit board in system unit is called the motherboard, it contains adaptor cards processor and memory chips. The mother can also be called the system board.

Chip: A chip is a small semi-conducting material where intergrated circuits can be etched. Integrated circuits have many microscopic pathways capable of carrying electric current. Chips are packed in a certain way so they can be connected to a circiut board.

Central processing unit (CPU): The CPU carries and interprets basic instructions that can operate a computer. The control unit coordinates operations in a computer. The Arithmetic logic unit (ALU) does arithmetic, comparison and logical operations. This can also be known as the processor.

Machine cycle: The machine cycle is the name of the four operations of the CPU. The first step is to 'fetch' the program instuction/data from the memory. The second step is to 'decode', which means translate the instruction into instructions. Step three is to 'execute', carry out the instruction. Finally step four is to 'store', write the result back to memory.

When something is permanently deleted where does it go?

On Windows based OS's, deleted items go to the Recycle folder (bin). Simply emptying the recycle bin does not rid the file from the hard drive. You may have to defragment the drive to really get rid of the files.

They do not just disappear into thin air ... a new file may simply overwrite the old one ... replacing the zeros with ones, for instance. The data changes.
