What would happen if the computer did not developed?
Computers are labor saving devices; everything that they do can be done by human beings, it just involves more work. Instead of email we would use regular mail, delivered by human mail carriers. So the economy would be less efficient, but then, there would also be less unemployment. Exactly what the overall consequences would be for society is difficult to say for sure, but my guess is that the world would have entered into a very serious global depression decades ago, if not for the economic stimulus resulting from the computer industry.
What is the pin number for this computer?
Try checking your system settings, the box that it came in, or take it to an electronics store.
What is the problem when you hear one long and two short beeps from computer?
Your computer usually beeps when it starts up, because it is indicating that it has passed the POST (Power On Self Test)tests. This is usually a good sign at start up. However, if you receive an odd beep pattern then there may be something wrong with your computer. The beeps are basically your computer trying to communicate hardware errors to you if there are any.

A Binary number is a number system to the base of two.
Answer--The binary numeral system, or base-2 number system represents numeric values using two symbols, usually 0 and 1. More specifically, the usual base-2 system is a positional notation with a radix of 2. Owing to its straightforward implementation in digital electronic circuitry using logic gates, the binary system is used internally by all modern computers.Eg:0-0
1-1
2-10
3-11
4-100
5-101
6-110
7-111
8-1000
There is no "the" binary number, although there is "a" binary number.
Binary is a system of numbers whch uses only 0 and 1 (or off and on), such as 010101010101101110. This is mainly used by computers. Another meaning of binary numbers is the possible numbers using binary with a certain number of digits. These numbers are 2 to the power of X where X is the numberof digits. There is no "the" binary number, although there is "a" binary number.

What are the three components of a dynamic system?
The three components of a dynamic system are state variables, inputs, and outputs. State variables represent the current status or condition of the system, inputs are external factors or influences that affect the system, and outputs are the results or responses produced by the system based on its state and inputs. These components interact continuously, leading to changes over time and influencing the system's behavior.
What function does the female port do on the computer?
The port of a computer is an interface between the computer and other computers or devices. The function of ports is to connect a monitor, webcam, speakers or other device through a specialized outlet.
Is the theft of a computer is considered cyber crime?
It is a property crime and can result in jail time. Cybercrime is crime using a computer, such as child porn, hacking, phishing, email scams, or fraud.
What are the factors that stop children from using computers?
Computer criminals and most of the time Internet predators.
Why do the military uses the computer?
Computers yes, can help the military. I know they help them organiaze missile launches, air strikes etc. They also help to create new generation weaponary for WW3 and other wars, and to orginiaze platoons of soldiers, and design vehicles of War, like Tanks etc.
Where can the input voltage selection be changed from 110 volts to 220 volts on a computer system?
The voltage can be changed for a computer in a few ways. The advanced way is through the BIOS. However this is not recommended for an everyday user! You can find a few programs online that will allow you to safely change the voltage and some that is still for advanced users but easier to do.
WARNING! Changing the voltage can permanently damage your PC. Most likely cause overheating. You should never change the voltage on a PC unless the goal is to overclock! Overclocking will void computer manufacture's warranties!
What are disadvantages of computer based information systems?
the start-up costs are high
peoples knowledge and skills are reduced due to lacl of practice
unemployment is created because computers have taken over humans jobs
when there is no electricity the computer cant operate
backups need to be created to prevent data being lost through viruses, ect.
the constant staring at the computer is bad for the operator
you need to get a storage device for the memory depending on how much memory is needed
A systems analyst is responsible for researching, planning, coordinating and recommending software and system choices to meet an organization's business requirements. The systems analyst plays a vital role in the systems development process. A successful systems analyst must acquire four skills: analytical, technical, managerial, and interpersonal. Analytical skills enable systems analysts to understand the organization and its functions, which helps him/her to identify opportunities and to analyze and solve problems. Technical skills help systems analysts understand the potential and the limitations of information technology. The systems analyst must be able to work with various programming languages, operating systems, and computer hardware platforms. Management skills help systems analysts manage projects, resources, risk, and change. Interpersonal skills help systems analysts work with end users as well as with analysts, programmers, and other systems professionals.
Systems analysts may act as liaisons between vendors and the organization they represent. They may be responsible for developing cost analyses, design considerations, and implementation time-lines. They may also be responsible for feasibility studies of a computer system before making recommendations to senior management.
Basically a systems analyst performs the following tasks:
* Interact with the customers to know their requirements
* Interact with designers to convey the possible interface of the software
* Interact/guide the coders/developers to keep track of system development
* Perform system testing with sample/live data with the help of testers
* Implement the new system
* Prepare High quality Documentation
What is the CPU and its importance to a computer system?
The CPU (Central Processing Unit) is the 'brain' of the computer so to speak. It handles all the arithmetic and calculations of the computer. Everytime the computer executes an action, it runs through the CPU before writing any results to storage. Without a CPU a computer can not function. This is a very simple explanation however, there is more detailed information out there that covers the ALU circuit and other things.

When was the first computer invented for everyday people to buy?
Remington Rand was the first company to sell computers - it sold the UNIVAC in 1951, eventually selling 46 machines at $1M each. To put this price into context, the average salery in the 1950s was around $3000.
Remington Rand was lucky to sell that many:
- Even though Remington Rand had bought EMCC, the makers of UNIVAC, they did not understand it or like it. They considered data processing could only be done on punched cards where a human could examine the card and see what was on it, not this mysterious new magnetic tape.
- Initially they did not train their salesmen to sell the machine. The salesmen also got no incentives or bonuses for selling a UNIVAC, like they were used to getting for every other Remington Rand product they sold. At this point if a customer wanted a UNIVAC he had to seek out a salesman himself and for all practical purposes "bribe" the salesman to order one for him.
- When they did decide to train the salesmen they assigned a man that wrote all the training and marketing materials for UNIVAC without talking to any of the EMCC designers or programmers of UNIVAC. If they tried to help him, he felt they were meddling and told them he didn't need them and get back to their work.
- When it became obvious to EMCC that Remington Rand was effectively sabotaging UNIVAC sales (through benign neglect), they sought permission and got it to assign a programmer to each sales office to assist in sales presentations. Since virtually all of EMCC's programmers were women, they got assigned first spot in the presentation and when they finished were hurried away so the "real" salesmen could come in and pitch "real" equipment like typewriters, desks, chairs, punchcard processing equipment, etc. To most Remington Rand salesmen the woman was "just for show" and was a good attention getter before the real sales pitch.
- Remington Rand lost one major multimillion dollar UNIVAC sale (that was practically already in the bag) because the programmer assigned to that office had become pregnant and could not travel to the customer's site or even work full days, and they wouldn't allow EMCC to find a replacement for her. Eventually the customer gave up in frustration and decided to wait another year for the IBM 701 to come out and they got one of those instead of UNIVAC.
