How do you make a plus minus sign with the keyboard?

The key should be on the top row of your keyboard on the right hand side on the same key as the = sign.

To get the plus (+) symbol press control and the key with both = and + on it.

Should be ~ to press the "Shift" key and the key with the (+) and (=) sign together or just use the number pad on the right side of the full keyboard with the (+) sign.

Why won't Feral Heart work?

You probably need to download the patch from the homepage.

List out various unethical use of computers?

Putting it simply, people get hurt and computers can be destroyed.

For example, if someone uses the computer to cyberbully, post personal information about someone (including phone numbers), hack accounts or scam, people can get hurt.

If someone spreads a virus on computers, they can at the least harm the computer and can sometimes destroy computers.

What is the best multimedia computer for 2009?

What is Parallel Programming?

when two independent processes take place at the same time. this is either done by virtual threading ( whareby each process or thread is assigned acces to resources for a fraction of the available time, then either volounteers or is forced to relinquish resources to another process for another fraction) or multi core processing, whareby 2 or more compleatly independent processsors handle diffrent processes simutaniously.

Is a super computer a personel computer?

No, "super computers" are so-called because of their capacity to perform enormous amounts of calculations which would exceed by far the demands of a normal computer or user. A fraction of a super computer's power would be more than enough to run any application that a normal user could dream of, so there would be no point in using it for normal purposes. It's kind of like having a car with a 3,000 horsepower jet engine on it- you really can't even use 1,000 horsepower for any normal driving so what would you do with even more?

When only a copy of the argument's value is passed into the paremeter variable?

By default, a copy of the argument's value is passed into the parameter variable. This is "call by value" semantics, and the called function can do whatever it wants with the parameter, but it cannot alter the original copy. Sometimes, in C and C++, you can pass the address of the value instead. This is "call by address" semantics, but the called function must be designed to handle it - in this case, the called function can alter the original value. (Actually, it is always "call by value" - what we call "call by address" is simply passing the value of the address, a subtle distinction which is important to understanding the language.)

How can you find out the path of device drivers?

It depends on the operating system. In Microsoft Windows, Device Manager lists all the hardware. Inspecting the properties of specific hardware will determine where the current drivers reside. Many will reside in the Windows\System32 folder, however they can be registered in any folder on the system. In Linux, however, all the modules can be found in /lib/modules/<kernel>.

The type of input that is a set of instructions that direct the computer?

No - an input device is a device that provides data input to a computer. A keyboard, mouse, microphone, and Web cam are examples of input devices. A monitor and speakers are examples of output devices.

A set of detailed instructions given to a computer is called a program.

What is COBOL grid?

COBOL stands for Common Business Oriented Language. It is the programming language used on computers for the purpose of business.

Who was the first person to actually program a thinking machine?

There is no such thing as a thinking machine. As such, to date, no one has actually programmed one. Thinking machines are the work of pure science fiction.

Artificial intelligence, on the other hand, is purely academic. To date, no one has been able to program a machine that exhibits intelligence of any kind. Artificial intelligence is, by definition, not intelligence, it is merely the illusion of intelligence. In order to be classed intelligent, a machine must be capable of fooling any human into believing there is actual intelligence at work. So far, none have succeeded, but work in this field is still at a very early stage.

IN which Programming language Windows Server 2000 is written?

Windows is not written in a specific programming language. The entire operating system itself is based on a kernel, which is written in Assembler, C, C++, and a few other high-level programming languages. If the Operating system were just a compiled program, people would be able to decompile it, which Microsoft does not want to happen. So, a variety of languages are used, compiled, and those are compiled together to make it. Sometimes, a programmer must use some binary for it to complete a function, and then they run it so it can be decompiled again, hence being closed-source. Linux is an open-source operating system that you can edit to your will. They give out the source code, and the kernel, so you can make your own operating system.

What is the programming language of Windows 7?

The foundation of Windows 7 is mostly written in C and a little bit of Assembly.

This is because a relatively low level language is required for access to processor registry management and connection with other devices (e.g. printer) to be established to the computer.

Most of the other core stuff is written in C++.

Lastly, there is a bit of C# written on the .NET Framework here and there, but the use of it is not that abundant (yet).

What is computer logic gates?

Logic gates are transistor circuits, normally arranged on a silicon base and encapsulated inside an integrated circuit. (chip).

Using several transistors wired together, their inputs can be arranged such that, for given inputs, the output will only change state for certain conditions.

The transistor switches are in either of two states, 'on' and 'off'. These are logic states 1 & 0 (one or zero), hence binary.

The logic uses Boolean algebra.

NOT, means it is 'not on', = OFF. This is abbreviated in the descriptions as the letter 'N'

A simple AND gate, means that the output is at level zero until both inputs have a level 1 voltage on them.

A NAND gate is a 'Not And' gate. The result is reversed. The output is always at logic level 1 until both inputs also have a level 1 also.

Write a program in assembly language to add two 8 bit numbers?

we can do this using two techniques:

here i m assuming that two number which is to be multiplied are given..

say 05H and 04H,

so coz 5*4 = 5+5+5+5 = 20

and 4*5 = 4+4+4+4+4 = 20

use this concept ...

MVI A,05H;

MVI B,04H;

L1:

ADD A;

DCR B;

JNZ : L1;

STA 2004H;

HLTType your answer here...

What is the frequency in Hertz of a signal that repeats 80000 times within one minute What is its period the length of one complete cycle?

Hertz is cycles per second, so 80,000 cycles per minute must be converted to cycles per second. This is accomplished, of course, by dividing 80,000 by 60, which results in 1333-1/3. So, this is a frequency of 1333-1/3 Hertz. As for its period, this is figured out by inverting the quantity. Frequency is expressed in cycles per second, as we already know, but the period is seconds per cycle. So, if the frequency is 1333-1/3 cycles per second, then the period is 1 second per 1333-1/3 cycles. So, divide 1 by 1333-1/3. This results in 0.00075 seconds, or to put it in more common terms, 3/4 of a millisecond.

I hope this helps. If you have any other questions, feel free to let me know.

System design vs system analysis?

System design and system analysis are both important stages in the development of a software system, but they focus on different aspects of the process.

System analysis is the process of studying and understanding the existing system and its requirements, including its functions, inputs, outputs, and user needs. System analysts work closely with stakeholders to gather and document requirements, create use cases, and develop models of the current system.

System design, on the other hand, is the process of creating a new system or modifying an existing system to meet the requirements identified during the analysis stage. System designers use the requirements gathered during the analysis stage to create a detailed design of the new or modified system, including its architecture, components, and interfaces.

In summary, system analysis is focused on understanding the existing system and its requirements, while system design is focused on creating a new system or modifying an existing system to meet those requirements. Both are important stages in the development of a software system, and they often overlap and inform one another. Effective system analysis and design can lead to the development of a high-quality software system that meets the needs of its users.
