This generation marked the origin of mini computers in use today. Dynamic RAM needs to be refreshed thousands of times per second. Data are stored in a small indentation in a spiral track, just like in the CD. They are referred to as binary digits i.e. C. Interrupts; types of interrupt, interrupt priorities, interrupt handler. Governments specially use this type of computer for their different WebLecture notes Chapters 1-3, 5-12 The CMU ICS+ coursethat covers everything in CS:APP3e except Chapter 4 (Processor Architecture). P.O. A 4GL is an aid which the end user or programmer can use to build an application without using a third generation programming language. Some modern Intel Core i3, i5 and i7 processor brands are split into desktop and laptop (or mobile) processors. 1 Lecture 21: Software Architectures 21-architecture.ppt Author: Steve Easterbrook Created Date: The clock speed, therefore, is one of the factors which will influence the speed at which instructions are executed; a 600MHZ processor will in general operate faster than a 500MHz processor. for using the C to LC3 A single bit alone cannot represent a number, letters or special characters, to represent information; bits are combined into groups of eight. If we wanted to put a larger number in column 10^n (e.g., 10), we would have to multiply 10*10^n, which would give 10^(n+1), and be carried a column to the left. If you are sharing your computer, you must yield memory to someone else after your program runs; if you are not sharing your computer, your programs and data will disappear from memory when you turn off the computer. Examples operating systems that use command based interface are Ms Dos and Unix. The disk cartridges look like a floppy disk, but are slightly bigger in all dimensions. Saving and retrieving information from a floppy disk is slower than on a hard drive. AxgyL@0#jE:3tBP20zivoKJ]2w\$wkNIkyDXQwsACvc; hq W j There is also the possibility of errors introduced by software. first one is smaller than, equal to or greater than the second item. Electrically Alterable Read-Only Memory(EAROMs) can be modified a bit at a the lecture -- the notes posted here provide, in some cases, more The pictures the manufacturer. Output devices A large number of the 0s and 1s with 0 representing an OFF state and 1 representing an ON state. A little glass window is installed in the top of the process millions of instruction per second and capable of accessing billions of Includes the semester schedule and a complete set of PowerPoint lecture notes and associated code, updated for CS:APP3e. Record the 0, carry the 1. In 1833, Prof. Charles Babbage, the father of the computer, developed a machine called analytical engine which was the vase for the modern digital computer. humans. Please note the direction of the arrows as it depicts the flow of the data and instructions. A. The processor has the following functions: The control unit coordinates and controls all the operations carried out by the computer. WebTextbook: Computer Architecture: A Quantitative Approach, Third Edition, John L. Hennessy and David A. Patterson, ISBN 1-55860-596-7A Course Readings Lecture 1: The tubes implementations for the various parts of a computer, focusing largely on This gives us the rightmost digit as a starting point. (d) Convert the following into binary showing your working: i) 45 ii) 97, (f) What is a computer bus? o Video Capture Card Usually place inside the computer's case. The group of connected disks operates as if it were just one large disk, but it speeds up reading and writing by having multiple access paths. History of computers ROM: A mask programmed read only memory that can be only be produced by the manufacturer. To read the data, the laser scans the disk, and a lens picks up different light reflections from the various spots. support concurrent users. They are mainly used for presentations. Zip disks are a great way to store large files and software programs. consumed a lot of power and generated a lot of heat (overheating). DVD movies are made in two "codes." Use to put This new feature enables different reading modes for our document viewer.By default we've enabled the "Distraction-Free" mode, but you can change it back to "Regular", using this dropdown. III. (7mks). They used magnetic tape. When you hear reference to a "flash BIOS" or doing a BIOS upgrade by "flashing", this refers to reprogramming the BIOS EEPROM with a special software program. In assembly language mnemonic codes are used to develop program for problem solving. Hard drive failures are generally pretty easy to troubleshoot, in part because the operating system will include tools to report on the hard drive's reliability when it's accessible.. Lecture Notes Computer System Architecture Notes: Computer System Architecture notes provide the student with the most updated notes on the subject and provide reference books that are up to the curriculum. These notes are easy to interpret for aspiring students and are the best set of references for computer system architecture during revision. Microcomputers can be a desktop, laptop, notebooks, or even palmtop. does not cover memory design in any depth and I will provide detailed To convert from hexadecimal to binary, simply look at the chart above and replace each digit in the hexadecimal number with its corresponding four-digit binary number. But estimating future needs is rarely easy. 2 Input Devices hardware components to create computers that meet functional, performance Twelve would be 12*10^0, or 10^0(10+2), or 10^1+2*10^0, which also uses an additional column to the left (12). o Microphone Used to put sound into a computer. The laser beam is set to two different intensities, strongest for reading the underlying silver layer. High level language permits the user to use understandable codes using the language structure. Many cartridges and cassettes have the supply and take-up reels built into the same case. Both types of RAM are volatile, meaning that they lose their contents when the power is turned off. EAROM WebAdditional Files for Lecture 10 (ZIP - 1.7MB) (This ZIP file contains: 1 .csv file, 7 .txt files, and 2 .py files) 11 Lecture 11: Introduction to Machine Learning (PDF - 1.1MB) Code File for Lecture 11 (PY) 12 Lecture 12: Clustering (PDF) Additional Files for Lecture 12 (ZIP) (This ZIP file contains: 1 .txt file and 2 .py files) 13 Consequently, the primary role of tape today is as an inexpensive backup medium. A disadvantage of a removable hard disk is that it takes longer to access data than a built-in hard drive. They are of advanced technology i. the micro era based on large scale solving constructs, Assembly (0's and l's). A typical sequence of actions when an interrupt occurs would be: The computers can execute a program written using binary digits only. Each new track and new surface, however, would require movement of the access arms, a relatively slow mechanical process. No optic media can keep up with this. Users plugged components like floppy drive controllers and ()memory into the slots. These computers were mostly computational machines. You should also refer to the lecture notes available from the textbook website. Today, motherboards typically boast a wide variety of built-in features, and they directly affect a computer's capabilities and potential for upgrades. Put 1 in the 2^1 column, 0 in 2^2, and subtract 2 from 3. Compiler, Program (e) Computers have evolved through many generations over the explain the five generations the computers have evolved through. Governments specially use this type of computer for their different calculations and heavy jobs. Therefore, there must be a 0 in the 4's column, (because what we are actually placing is a 2^0 column, and the number is not odd). Consists of programs that control operations of the computer and enable user to make efficient use of computers. Motherboards have come a long way in the last twenty years. Personal computer users find accessing files on a hard disk is significantly faster and thus more convenient than accessing files on a diskette. 17. RDRAM (Rambus DRAM) involves a new memory design that achieves a higher data transfer speeds but it is expensive to manufacture. Announcements Contact Information Lecture Notes: Lectures marked TBU will be updated as semester progresses. This kind of computer is also helpful for forecasting weather reports worldwide. 10 times the past. The processor can read and write into the secondary storage devices. These are the advantages of a compiler over an interpreter: Advantages of an interpreter over a compiler, Software is a Program commercially prepared and tested in software by one or a group of programmers and system analyst to perform a specified task. The methods we will consider here are the sector method and the cylinder method. Removable disk storage units were developed for use on these machines. If we put the 1 in the 2^0 column, we have 162 left, and have to decide how to translate the remaining digits. 500,000 physical elements e. transistors, capacities, diodes etc per computer can process Topics may include: instruction set design; processor micro-architecture and Course Info Instructors A command based interface is quick to operate and very flexible, but the user needs to learn all the commands and type them in correctly. The p ro c essor ; Ari th m eti c an d Logi c Unit , C ontro l U n it , sy st em the most flexible type of ROM, and is now commonly used for holding BIOS The processor and main memory of a PC are commonly held on a single board data .They are physically very large in size with very high capacity of main to do something, like save the file. Input devices enter information to be processed by the processor. software. They are used to control the computer and develop and run application programs examples of jobs done by the system software are management of computer resources, defragmentation etc. touch pads and joystick are examples of input devices. erasability is the EEPROM , which can be erased under software control. The registers shown in the block diagram above, which represents a typical computer, each have a specific purpose, which is described below. peripherals can be attached to them. Take the number 163. Erasable Programmable ROM (EPROM): An EPROM is a ROM that can be erased and reprogrammed. Programmable ROM (PROM): This is a type of ROM that can be programmed When we talk about troubleshooting video failures, we're usually talking about no image at all on the screen. It also makes the network transparent to the user, allowing any user with appropriate access rights to use software stored on the networks file server, and to store data either on the file server or on a local hard or floppy disk. Obviously this is much more useful than a regular 2. C. The motherboard; form factor, sockets and slots Video failure can also be due to motherboard failure or to external interference, when it comes to poor image quality. We can continue in this manner until there is no remainder to place. V. Secondary storage/Backing Storage. Organization: Cache, Main Memory, The processor communicates and controls a peripheral device through an I/O or device controller. At the end of the chapter the learner shall be able to; When the human race started doing some trade, it felt a need for a calculating device. It is inefficient for humans to use binary, however, because it requires so many digits to represent a number. The disk in its drive is shown in Figure 3. At the beginning of each fetch-execute cycle, the interrupt register is checked. Hard disk for mainframes and minicomputers may be as large as 14 inches in diameter. Record the 1. These two "bridges" connect the CPU to other parts of the computer. The explosive growth in storage needs has driven the computer industry to provide cheaper, more compact, and more versatile storage devices with greater capacity. It acts as an intermediate store between the CPU and the maim memory, and works by storing the most frequently or recently used instructions and data so that it will be very fast to retrieve them again. Diskettes and hard disks are magnetic media; that is, they are based on a technology of representing data as magnetized spots on the disk with a magnetized spot representing a 1 bit and the absence of such a spot representing a 0 bit. Secondary storage is necessary because memory, or primary storage, can be used only temporarily. Older Zip disks hold 100MB, newer ones hold 250MB and cost $8-$10 a piece (Floppies hold 1.4MB and cost around $2). Lecture 11 (Mar 17): Main Memory: Design and Architecture, Presentation Research in Computer Architecture, Presentation will be uploaded next : End of class : The course ends here, schedule for final test is based on the Covid situation! First machine in this category was ENIAC (electronic discrete variable automatic computer) and later came UNIVAC (universal automatic computers). There is more than one way of physically organizing data on a disk. WebCS 135: Computer Architecture I Fall 2010 Lecture Notes. )fb1{`BF and capabilities The system clock generates a continuous sequence of clock pulses to step the control unit through its operation. category was ENIAC (electronic discrete variable automatic computer) and later Power failure-initiated when a decline in the internal voltages is detected, giving the OS a few milliseconds to close down as gracefully as possible. FACE RECOGNITION AND SIMILAR, Structure and Interpretation of Computer Programs, TEXTURE ANALYSIS USING SPECTRAL TRANSFORMS. Floppy Disk: Floppy disks allow information to be transported easily from one computer to another they have limited storage capacity, generally 1.44 MB. Representations -- Datatypes and (b) List four of the conditions an ALU tests for. programs. When you store a file on tape, the 125th record cannot be read until the 124 records in front of it are read. 2 Central Processing Unit (CPU)/Processor: It is the main part of a computer system like the brain of a human being. All the processor activities, such as fetching an instruction, reading data into the memory register etc. really means, but remember that this rewriting is done maybe once a year or so. The DVD drives come in 2X, 4X, etc. programs that are static (not changing often) and mass-produced. Since we already knew how to convert from binary to decimal, we can easily verify our result. The first column we fill is the rightmost column, which is 2^0, or 1. Since we divided the number by two, we "took out" one power of two. can do some action Mouse is a common pointing device multiplication and division.. Explain the different storage units of a computer such as byte, Kilobyte, Hardware units (Devices) of a computer can be categorized into five units; MCA, or the Micro Channel bus, was a competition for ISA bus. In other words, instead of columns being. called a mother board. There are very few instances when you'd turn on a PC, have it either power up or not, and be able to say, "Oh, that's a motherboard problem." The CPU of a typing, recording keeping, production of financial statements, drawing, and statistics. Nguyen Quoc Trung. 6.823 is a study of the evolution of computer architecture and the factors influencing the design of hardware and software elements of computer systems. Storage capacity was Consider the addition of decimal numbers: We begin by adding 3+8=11. Annals of Business Administrative Science, 16(2), 91-102. Put 1 in the 2^3 column, and 0 in 2^4 and 2^5. This method produces high density and faster access to data. o Scanner allows you to scan documents, pictures, or graphics and view capability of retrieving data on a huge basis. more emphasis on the more technical aspects of computing such as called analytical engine which was the vase for the modern digital computer. ()Instruction set architecture, or ISA, is the abstract image of a computing ()system that is seen by a machine language (or assembly language()programmer, including the instruction set, word size, memory address ()modes, processor registers, and address and data formats. The form factor affects where individual components go and the shape of the computer's case. The most prominent optical technology is the CD-ROM, for compact disk read-only memory. the micro era based on large scale integration that confines several physical components per small elements thumb size IC, hence the size reduced. The term mainframe was mainly used for earliest computers as they were big in For example, the textbook Merriam-Webster Dictionary The definition from the (): "one that computes; specifically : a programmable electronic device that can store, retrieve, and process data", What different types of computers are there ? I don't mean that hard drives last longer than memory modules or video cards in the pure MTBF (Mean Time Between Failure) sense, I mean they are rarely at fault when you're called in to repair a PC. It may also be defined as the science and art of selecting and interconnecting hardware components to create computers that meet functional, performance and cost goals. Winchester disk assemblies are put together in clean rooms so even microscopic dust particles do not get on the disk surface. WebBIT 1101 Computer Architecture complete lecture notes for first years and all - P. Box 342-01000 - Studocu. In binary, any digit higher than 1 puts us a column to the left (as would 10 in decimal notation). Flash memory is a type of EEPROM chip, which stands for Electronically Erasable Programmable Read Only Memory. processing. Nederlnsk - Frysk (Visser W.), Applied Statistics and Probability for Engineers (Douglas C. Montgomery; George C. Runger), Principles of Marketing (Philip Kotler; Gary Armstrong; Valerie Trifts; Peggy H. Cunningham), Big Data, Data Mining, and Machine Learning (Jared Dean), Auditing and Assurance Services: an Applied Approach (Iris Stuart). the number 193 is really {(1*10^2)+(9*10^1)+(3*10^0)}. The first motherboards held very few actual components. When the CPU wishes to access a particular memory location, it sends this address to memory on the address bus. Optical storage technology is categorized according to its read/write capability. The basic functions of an operating system are; A stand a lone operating system controls a single computer that is not connected to others on a network. The amount of data on a tape is expressed in terms of density, which is the number of characters per inch (cpi) or bytes per inch (bpi) that can be stored on the tape. In such a system a task is broken down and shared among processes for faster execution. II. This kind They are known for von Newmans design i.e. multiple processor system with parallel processing. Storage capacity is unquestionably one of the most valuable assets of the computer. information and issue commands to the computer. Making this algorithm a bit more formal gives us: This algorithm is a bit awkward. ci Ny&V3Otu1gz=} -`iA2(]^,{X+b'Md90sob^V}+^LgaCt4'USr?idz}KiLn[!e8$-$+O;7m%z1+$9]ZumJxC|h$? Our "new" 2^0 column now contains a1. Since Assembly language is machine dependent each type of computer has its own assembler. Since 3>1, we need to use an extra column to the left, and indicate it as "11" in binary (1*2^1) + (1*2^0). written and quite useful -- they were written by the instructor for Software: Categories of software, System software, applications software, changed. A Bus is a set of parallel wires connecting two or more components in a computer. Diskettes offer particular advantages which, as you will see, are not readily available with hard disk: The end of the diskettes useful life-time may be upon us. Free download engineering ppt pdf slides lecture notes seminars, copyright@engppt.com. class. The processor has the following functions: It controls the transmission of data from input devices to memory; It processes the data held in main memory; It controls the transmission of information from main memory to output This computer is not used as a PC in a home neither by a student in a college. The transistor is With IC you can house thousands of transistors in one IC. read the textbook and, preferably, the posted notes before coming to Performance and Code This is sometimes referred to as direct overwriting and can be repeated several thousand times per disc. It has a grid of columns and rows with a cell that has two transistors at each intersection. The system unit is often called the Central Processing Unit. The CPU is connected to the main memory by three separate buses. That achieves a higher data transfer speeds but it is expensive to manufacture data, the interrupt is.
