![]() ![]() Therefore, we determine the speed of computer in terms of microsecond (10-6 part of a second) or nanosecond (10 to the power -9 part of a second). From this you can imagine how fast your computer performs work. Accuracy: - The degree of accuracy of computer is very high and every calculation is performed with the same accuracy. The accuracy level is 7. Determined on the basis of design of computer. The errors in computer are due to human and inaccurate data. Diligence: - A computer is free from tiredness, lack of concentration, fatigue, etc. It can work for hours without creating any error. If millions of calculations are to be performed, a computer will perform every calculation with the same accuracy. Due to this capability it overpowers human being in routine type of work. Versatility: - It means the capacity to perform completely different type of work. You may use your computer to prepare payroll slips. Next moment you may use it for inventory management or to prepare electric bills. Characteristics of Computers A computer is an intelligent amplifier that performs the above-mentioned. The characteristics possessed by computers can be listed as. Data in computer terminology means raw facts such as name of a person, name of a city, amount of a thing etc. For eg: Sachin, 1947, A, -160.5 are data. A processed data is called information. That is, data are aggregated and summarized in various meaningful ways to form information. Characteristics of Computers 1. ADVERTISEMENTS: Let us make in-depth study of the characteristics and limitations of computer system. Characteristics of Computer System: A computer system is better. History Of Computers PdfPower of Remembering: - Computer has the power of storing any amount of or data. Any information can be stored and recalled as long as you require it, for any numbers of years. It depends entirely upon you how much data you want to store in a computer and when to lose or retrieve these data. No IQ: - Computer is a and it cannot do any work without instruction from the user. It performs the instructions at tremendous speed and with accuracy. It is you to decide what you want to do and in what sequence. So a computer cannot take its own decision as you can. No Feeling: - It does not have feelings or emotion, taste, knowledge and experience. Thus it does not get tired even after long hours of work. It does not distinguish between users. Storage: - The Computer has an in-built memory where it can store a large amount of data. List Of Characteristics PdfYou can also store data in secondary such as floppies, which can be kept outside your computer and can be carried to other computers. Introduction To Computers PdfADVERTISEMENTS: Let us make in-depth study of the characteristics and limitations of computer system. Characteristics of Computer System: A computer system is better than human beings in a way that it possesses the following capabilities: (i) Speed: Speed is the amount of time taken by the computer in accomplishing a task of an operation. The time taken by a computer to perform a particular task is far less than that taken by than a human being. Different computers are classified on the basis of their speed by comparing their MIPS (Million Instructions Per Second). (ii) Accuracy. ADVERTISEMENTS: Accuracy refers to the degree of correctness and exactness of operations performed by a computer. In the absence of bad programming, computers do not commit errors and are capable of handling complex instructions accurately. If the data fed into a computer is not error free, it is likely to produce inaccurate results. (iii) Reliability: Computer systems are non-respondent to human factors like fatigue, tiredness or boredom. Therefore, they are more likely to work repeatedly and efficiently. In case of any failure in a computer system, there are provisions for immediate backup of information and programs. (iv) Versatility: Computers are capable of performing all levels of tasks- simple or complex. Therefore, they can be used in any area-science, technology, business, finance, accounts, communications and so on. (v) Storage: It refers to the capacity of a computer to store data and programs. Storage is done in storage media such as CDs, Floppies, DVDs, RAM (Random Access Memory), ROM (Read Only Memory). Limitations of a Computer System: Although a computer is far better in performance than a human being, it fails in certain ways as follows: (i) Computers can’t Think. ADVERTISEMENTS: Computers cannot think and they can’t do any job unless they are first programmed with specific instructions for same. They work as per stored instructions. Algorithms are designed by humans to make a computer perform a special task. This is also called artificial intelligence. (ii) Computers can’t Decide: Computers are incapable of decision making as they do not possess the essential elements necessary to take a decision i.e.
