(Bit is the abbreviation for BINARY DIGIT). They have a word-size of 4 bytes and use a large memory unit, say, of size 16MB. It is made up of 3 main sections, namely: The ALU is to perform the Arithmetic and Logical operations. Android is a Best Mobile O/S and its Latest Android Version, The sequential computing is traditional architecture. The total number of locations in any memory unit will be in the order of 2n where n is an integer and will be equal to the number of lines or bits in what is known as ADDRESS BUS. The computer for processing Business data should be able to handle a number of files simul­taneously and each of these files may contain a large number of records. Your email address will not be published. Their ability of parallel processing and their well-designed memory hierarchy give the supercomputers, large transaction processing powers. The most prevalent type of digital computers is micro systems. Replies. IBM 360 and 370 are examples of large computers. Replies. Federal Board | Past Papers | Notes | A-Level. The highly calculation-intensive tasks can be effectively performed by means of supercomputers. The supercomputers have many processors operating in parallel. Computer is electronic is device so it contains the different hardware components such as circuits, transistors and wires etc. Digital computers store data in a numerical format. Reply Delete. Most of the present-day digital computers are versatile computers. In this model all instructions are performed one by one so speed of this computing is slow compare to parallel computing. Following are some types of Digital Computers on the basis of power, speed ,size and memory: 1. Using successive multi­plications, Exponentiation (raising a number to some power) can also be performed in a Digital Computer. Privacy Policy 8. Very bad. Disclaimer 9. They do not occupy space as much as mainframes do. Mainframe Computers Unknown November 29, 2019 at 7:11 PM. A supercomputer is architectural and operational totally depend on parallel and grid processing, because with the help of thousand of processor all processes are executed simultaneously. Unknown February 13, 2019 at 8:16 PM. This type of computer typically includes some sort of device to store information, some method for input and output of data, and components that allow mathematical operations to be performed on stored data. Whenever an expression like log(x) or sin(y) are used in the user’s program, the processor will execute the corresponding Library Function and compute the result. It may be noted here that the present-day Digital Computer can take in and process alphameric or string data also. Depending on the performance and size, the digital computers can be classified as: The Desk Top Computers or the Personal Computers (PC’s) fall under the category of micro­computers. Microcomputers Reply. (iv) It is very fast. 3. A mainframe computer was designed to be used process large amounts of data in pet bytes. Content Filtrations 6. It is not that a computer can use only one input device and one output device at a time. The MEMORY or the Storage device is composed of a number of locations, (e.g.,) A MEMORY of size 8 K (8 kilo) will have 8192 locations which will be referred to or addressed as 0000 to 8191. The digital computer is essentially a counting machine. These are called Library Functions. Pls oh I wanna get somtin right; If those are types of digital computers, then what are the five types of computers? As such, it cannot evaluate logarithms and trigonometric functions like sin 9. The storage unit is also called the MEMORY. Copyright 10. Quantum physics, mechanics, weather forecasting, molecular theory are best studied by means of supercomputers. So sub-programs, known as FUNCTIONS, are prepared by the manufacturer to evaluate such functions using some numerical methods and they are permanently stored in the memory. These 8 bits are used to store any character in the Binary form. It able controls thousands of users at one time. Characteristics. These computers use a Micro-Processor for the CPU. The sequential computing is traditional architecture. (iv) To store the partial or intermediate results. A File contains the records of same type or transaction. The present-day Digital Computer is an electronic device. Content Guidelines 2. Analog computer uses some physical fact’s continuously variable for solving problems such as mechanical, hydraulic and electrical quantities. In the Digital Computer, all calculations and other operations are represented in the form of digits such as binary system “0” and “1”. Prohibited Content 3. The Screen and the Printer are the mostly used output devices. The input-output devices are often referred as I.O. The Logical Operations that can be performed in a Digital Computer are, checking whether a variable, say, A is equal to or greater than or less than another variable, say, B or a constant. Hybrid Computers are combination both analog and digital computers, because these computers are able to execute both data such as analog and digital. Minicomputers Mainframe computer uses the primary memory such as (RAM) and multiple processors. A computer with a microprocessor and its central processing unit is known as a microcomputer. These computers take input in the form of analog signals, convert them into digital, and produce the output in digital form. Digit computer basically knows how to count the digits. Computers used for business and scientific application are digital computers. A group of such 8 bits is referred as a BYTE. To take out data or send data to either the memory or the I.O. In which had been used the different technologies such as transistors and core memory. (c) Versatile computers, depending upon their applications. These computers can fit on desks or tables and prove to be the best choice for single-user tasks. Anything that is variable concerning time and ceaseless can be asserted as simple clock measures through the separation fixed to the clock spokes through time, much the same as simple clock measures. After reading this article you will learn about:- 1. For example, the set of marks-cards of the students of the same class will constitute a file. In which had been used the different technologies such as transistors and core memory. Desktop and laptop computers typically have the … It can be termed as a Counting device which takes in a numeric data, processes it and gives out a result which is also numeric.
