A computer is not capable enough to make any decision on its own. A computer, at the lowest level, stores data in binary, a numeral system in which there are just two digits, 0 and 1. Through this article, learn about the basic fundamentals of computers, their applications in various domains, advantages, and disadvantages, followed by generations and types of computers. which we pass as input again to the say block: We can try to make Scratch (the name of the cat) say meow: But when we click the green flag, we hear the meow sound over and over immediately. A computer performs (if instructed to do so) the steps shown in the diagram below, using information that a user . The syllabus is the framework for the teacher to follow while this text book is a resource for the student. Over 2,500 courses & materials Freely sharing knowledge with learners and educators . Memory is a very important characteristic of computers. The set of instructions or programs that make the computer function using these hardware parts are called software. Lecture Notes | Computer System Architecture | Electrical Engineering and Computer Science | MIT OpenCourseWare Lecture Notes The course material is divided into five modules, each covering a set of related topics. 2020/2021 None. However, modern computers can do a lot more than calculate. language, An elementary operation in a programming language, The complete collection of instructions that are understood by a CPU, The set of operations that the computer can perform, RISC (Reduced Instruction Set Computer) e. ARM, MIPS, CISC (Complex Instruction Set Computer) e. X. E. if data bus is 16 bits wide & each instruction is 32 bits long A Textbook for Year 11 - Computer Studies. Output Unit Devices like printer and visual display unit that are used to provide information to the user in desired format are called output unit. If a system is already running but needs to be restarted, it is called rebooting. Therefore departure to other resource materials for more information will be acceptable. Each instruction has to be given to the computer. Our final solution, is like the green line: logarithmic, since our time to solve rises more and more slowly as the size of the problem increases. Using the notes provided by this article will help students better prepare for the subject by giving them in-depth knowledge and help in scoring better grades. Electrical Engineering and Computer Science; As Taught In Fall 2006 Level Graduate. Computer Fundamentals MODULE 1 Basic Computing Notes Computer Science 3 z Central Processing Unit (CPU) : This is known as the Brain of the Computer as it controls the complete working of the computer. My Library. Integration of the memory: the TLB and cache, 3.4.1. <> Well start calling these, We also have branches that lead to different paths, like forks in the road, which well call, And the questions that decide where we go are called, Finally, we have words that lead to cycles, where we can repeat parts of our program, called. memory, A number of wires indicate the address of data to be accessed, Bus width determines maximum memory capacity of system (the number of memory assignment_turned_in Programming Assignments with Examples. Computers can do the same task repetitively with same accuracy. thousands of connected users simultaneously, A supercomputer is the fastest, most powerful computer, Capable of processing trillion instructions in a single second. 277 If we wanted to represent 8, we would need another digit: And binary makes sense for computers because we power them with electricity, which can be either on or off, so each bit only needs to be on or off. It can store any type of data such as images, videos, text, audio, etc. UNIT IICentral Processing Unit: The 8086 Processor Architecture, Register organization, Physical memoryorganization, General Bus Operation, I/O Addressing Capability, Special Processor Activities, Minimumand Maximum mode system and timings.8086 Instruction Set and Assembler Directives-Machine language instruction formats, Addressingmodes, Instruction set of 8086, Assembler directives and operators.

Input primarily is the raw data for which the system gives a meaningful outcome. Computer hardware is the collection of physical elements that constitutes a computer system. A computer is an electronic device that accepts data/inputs from its user and processes it into useful information as per the processing instructions to generate the output. Which holds the following characteristics: Using vacuum tubes; dedicated to code breaking, The third generation: Integrated circuit (IC), Lots of devices on one bus leads to Propagation delays, Long data paths mean that co-ordination of bus use can adversely affect Some of these lines start with verbs, or actions. With 1024 pages to start, we would only need 10 steps of dividing in half before we have just one page remaining to check. File Permissions: access control, umask, chmod, chown, chgrp, Set-UID. Lecture 4 : Software and Architecture Types. Contact Us Basic Computer Notes Simple language that you can understand in one reading Notes in Different Category We could also flip two pages at a time, but if we go too far, well have to know to go back a page. We start by looking at the different types of computer components and how they interact during basic computer operations. We cannot see or touch software. It is a new text book and the first of its kind to be written locally.

Operation of virtual memory: paging, segmentation, paged segments, 3.3.2. Regular electric supply is necessary to make computers work, which could prove difficult everywhere especially in developing nations. It can perform the calculation of a very huge amount of data. Sorry, preview is currently unavailable. endobj For example, we might want to have Scratch cough three times by repeating some blocks: While this is correct, we can avoid repeating blocks with a loop: The next step is abstracting away some of our code into a function, or making it reusable in different ways. Raw facts and figures which can be processed using arithmetic and logical operations to obtain information are called data. double approximately every two years, The growth of processing power in terms of MIPS seems to have a tendency What a computer system architecture entails is the design of the computer system and how it functions with the various categories that are microarchitecture, instruction set architecture and system design, all these categories are what constitute the basic CPUs architecture, and it is the key in the function of the computer as a whole. 9-N!? Students can download all these notes easily from the internet for free. Next, we focus specifically on the CPU (Central Processing Unit). It is not smart enough to make a judgment based on experience, feeling, taste, and knowledge just like humans. Macintosh Technology in the Common Hardware Reference Platform by Apple Computer Inc. PowerPC Microprocessor Common Hardware Reference Platform by Apple Computer Inc., International Business Machines, Inc., and Motorola Inc. All of these languages, including Scratch, has more powerful features like: the ability to store values and change them, the ability for our program to do multiple things at once, the ability to respond to changes in our program or inputs. Servers, Mainframes and Supercomputers: A server controls access to the hardware, software, and other resources on a network, A mainframe is a large, expensive, powerful computer that can handle hundreds or It works according to the users instruction, thus it is entirely dependent on humans. In binary, with just two digits, we have powers of two for each place value: Now if we change the binary value to, say. 3 0 obj This whole process is completed with the help of input unit, output unit, storage unit, arithmetic logic unit, control unit. General Purpose computer; Special purpose computer; Four Components in a Computer System: Hardware . The basic parts of a computer are as follows Input Unit Devices like keyboard and mouse that are used to input data and instructions to the computer are called input unit. 2 0 obj 1943-46: ENIAC (Mauchly, Eckert, University of Pennsylvania).
