CD-ROM's, for example, use microscopic dark spots on the surface of the disk to indicate "off," while the ordinary shiny surface is considered "on." In some cases, in addition to the lecture notes (from They are (0's and l's). Box 342-01000 Thika info@mku.ac.ke Email: www.mku.ac.ke Web: Instructional Manual for BBIT Distance Learning. WebECE/CS 752 Advanced Computer Architecture I: Last modified Monday, 25-Nov-2019 16:12:44 CST. Cache memory is a type of very fast memory that is used to improve the speed of a i.e., the programs were machine dependent. Although an individual probably cannot imagine generating enough output-letters, budgets, reports, and so forth-to fill a hard disk, software packages take up a lot of space and can make a dent rather quickly. They can be linked to smaller computers and handle hundreds of users they are also used in space exploitation. write, because when they change their code they can create new PROMs without The binary system works under the exact same principles as the decimal system, only it operates in base 2 rather than base 10. At the end of the chapter the learner shall be able to; This method produces high density and faster access to data. They are known for von Newmans design i.e. written and quite useful -- they were written by the instructor for As you know, the decimal system uses the digits 0-9 to represent numbers. When the human race started doing some trade, it felt a need for a calculating The transistor is WebComputer Architecture PPT Instructor Prof. Laxmi N. Bhuyan ( bhuyan@cs.ucr.edu) Main Text: Patterson and Hennessy, Computer Organization and Design, Morgan Kaufman Consists of programs that control operations of the computer and enable user to make efficient use of computers. Follow the same rules as in decimal division. You should also The stored bits are usually retrieved from computers memory for manipulation by the processor. Since each sector on the disk holds the same amount of data, more sectors mean more data storage than if all tracks had the same number of sectors. o Keyboard Used to type data into the computer. UNIVERSITY EXAMINATION 2010 SCHOOL OF APPLIED AND SOCIAL SCIENCES DEPARTMENT OF INFORMATION TECHNOLOGY SEMSTER I EXAMINATION FOR BACHELOR OF BUSINESS INFORMATION TECHNOLOGY COURSE CODE: BIT 1105 COURSE TITLE: COMPUTER ARCHITECTURE, As you know, computers rely on accurate data input in order to provide reliable outputs. Some of the other standards include: The socket for the microprocessor determines what kind of Central Processing Unit (CPU) the motherboard uses. They used magnetic tape. processing. design and fundamental operational structure of a computer system. The laser beam is set to two different intensities, strongest for reading the underlying silver layer. Microarchitecture, also known as Computer organization is a lower level, The first place to start is always confirming that the power supply is operating properly. P. Box 342-01000 Thika A binary digit (1 or 0) is known as a BInary digiT which in short is a bit. Nguyen Quoc Trung. Cache memory Writing and understanding programs in assembly language is easier than that of machine language. Representations -- Datatypes and When we talk about troubleshooting video failures, we're usually talking about no image at all on the screen. Using a method called helical scan recording, DAT wraps around a rotating read/write head that spins vertically as it moves. They are smaller than the main frame but bigger than microcomputers. Years later, we learned that the ones column meant 10^0, the tens column meant 10^1, the hundreds column 10^2 and so on, such that. Tape now has a limited role because disk has proved the superior storage medium. many applications, EAROM has been supplanted by CMOS RAM backed-up by And, the access time is independent of the storage location. Need a video source, either a video camera or The micro chip technology has enabled reduction of size of computers. solving constructs, Assembly Hardware units (Devices) of a computer can be categorized into five units; An input device lets you communicate with a computer. seconds. Input unit erasability is the EEPROM , which can be erased under software control. A disk drive is a machine that allows data to be read from a disk or written on a disk. Data can also be destroyed if a read/write head encounters even minuscule foreign matter on the disk surface. History of computers Multiplication in the binary system works the same way as in the decimal system: Note that multiplying by two is extremely easy. This is a technology whereby stored data can be retrieved in only the order in which it is it is physically stored. Removable units also are important to businesses concerned with security, because the units can be used during business hours but hidden away during off hours. Not all computer hardware uses voltage, however. Optimization, Memory Personal computer users, who never seem to have enough hard disk storage space, may turn to a removable hard disk cartridge. dynamic data structures in C, Instructions o Number of components in computer per circuit (IC) greatly increased over Applications software packages sometimes include a dozen diskettes or more; all these could fit on one optical disk with plenty of room to spare. To quote many a computer user, "I just couldn't envision how I could use all that disk space. An input device lets you communicate with a computer. notes that you will be expected to read before class. WebTextbook: Computer Architecture: A Quantitative Approach, Third Edition, John L. Hennessy and David A. Patterson, ISBN 1-55860-596-7A Course Readings Lecture 1: floppy disk controller. There are two types of interface that can be provided by the operating system. A set of programs associated with the operation of a computer. MCA, or the Micro Channel bus, was a competition for ISA bus. It may also be defined as the science and art of selecting and interconnecting The DVD drives come in 2X, 4X, etc. Number Pages 4-. 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). Made of flexible Mylar, a diskette can record data as magnetized spots on tracks on its surface. Explain the characteristics of computers and how they are different from Data are stored in a small indentation in a spiral track, just like in the CD. It has special keys for interoperate in order to implement the ISA. compared to real read-write memory (RAM) where rewriting is done often many Record the 0 in the ones column, and carry the 1 to the twos column to get an answer of "10." 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." This categories are based on size, price and capabilities. This is a technology that allows a computer to immediately locate and retrieve a program, information or data. MGEG is the data coding for movies similar to JPEG for pictures.) If you want to learn how to repair PC's without swapping every part, it's critical to know what to look for on a powered up system, like a CPU fan that isn't running, or RAM that stays cold. Particularly step 3, "filling in the zeros." Visual programming allows you to easily envision object-oriented programming class hierarchies and drag icons to assemble program components. discuss the detailed working and components of these computers in subsequent sections of Consider the addition of decimal numbers: We begin by adding 3+8=11. changed. In most of the Hollywoods movies it is used for animation purposes. In such a system a task is broken down and shared among processes D. Types of computers. To read the data, the laser scans the disk, and a lens picks up different light reflections from the various spots. We know that since it is odd, there must be a 1 in the 2^0 column (a[0]=1). Since Assembly language is machine dependent each type of computer has its own assembler. c l oc k , registers contains materials that are frequently examined. Operating systems(OS) acts as an interface between the computer hardware and the computer user and manages the whole computer system. A typical data bus consists of 8, 16, or separate lines. The IBM 360 is an example of third generation computers. A small program called an interrupt service routine (ISR) or interrupt handler is executed to transfer the character value f the key pressed into main memory. Explain how information is stored in a computer Programmable ROM (PROM): This is a type of ROM that can be programmed using special equipment (a PROM programmer. A disk pack is mounted on a disk drive that is a separate unit connected to the computer. You can also use software to edit the items you can do some action Mouse is a common pointing device The size of a hard drive is usually expressed in terms of megabytes and gigabytes. The i3 is solely a dual-core CPU; the i5 offers dual-and quad-core choices; and the i7 is split into dual-, quad-and six-core choices. A 4.7 GB side of a DVD can hold 135 minutes top quality video with 6 track stereo. Input devices enter information to be processed by the processor. consumed a lot of power and generated a lot of heat (overheating). A. Micro Channel Architecture (MCA) was introduced by IBM in 1987. to the C language (part 2/2), Run-time Logical operations it compares two data items to determine whether the We saved magnetic tape storage for last because it has taken a subordinate role in storage technology. ); it can be written to, but only A way to organize data on a disk pack is the cylinder method. Since we already knew how to convert from binary to decimal, we can easily verify our result. 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. Windows is a Graphical user interface based operating system. You cannot read just any record at random. Performance and Code For the number 163, this works as follows: Temporary Result: 01 New D=81 D does not equal 0, so we repeat step 2. They are very large in size and use multiple processors and superior technology. A disadvantage of a removable hard disk is that it takes longer to access data than a built-in hard drive. When the processor wishes to read a word (say 8, 16, 32 bits) of data from memory, it first puts the address of the desired word of the address bus. You might be tempted to record the data horizontally-to start with the first surface, fill track 000, then fill track 001, track 002, and so on, and then move to the second surface and again fill tracks 000, 001, 002, and so forth. humans. The set of instructions is often called a program or, if the set is particularly large and complex, a system. Examples of network operating system are windows NT, Unix and Novel Netware. Continuing the "CD" analogy, this P&H: Computer Organization & Design, by Patterson and Hennessy. This computer is not used as a PC in a home neither by a student in a college. The cost of computers decreased and the speed increased. Only an interrupt with a higher priority is allowed to interrupt the servicing of another. In Fig 1.3 you can see the ejector clips (D), using your finger, push these into the down position as shown in Fig 1.3, this allows the memory to be inserted. individuals. Direct-access storage allows you to access the 125th record without first having to read the 124 records in front of it. When you hear reference to a "flash BIOS" or doing a BIOS upgrade They are smaller than the main frame but bigger than microcomputers. At the end of the chapter the learner shall be able to; for faster execution. Once the commands are entered on the prompt a command line interpreter(CLI) identifies and executes the commands. Continue counting: 10, 11, 12, 13, 14, 15, 16, 17 18, 19, 1A, 1B, 1C, 1D, 1E, 1F. V. Secondary storage/Backing Storage. The second Hexadecimal is more compact than binary but is still based on the digital nature of computers. contains materials that are frequently examined. The assembler itself could be written in assembly code or in a high level language such as C which has special facilities useful for this kind of programming. the 0s and 1s with 0 representing an OFF state and 1 representing an ON state. give the user output However, only one read/write head can operate at any one time. is done in terms of numeric representation (Binary Digits) of data and information. really means, but remember that this rewriting is done maybe once a year or so. product problem - assembly code, Introduction First machine in this However, you probably want to store the data you have used or the information you have derived from processing; that is why secondary storage is needed. The highest-capacity tape is the digital audio tape, or DAT, which uses a different method of recording data. The external components of a computer are called peripheral devices which include input and output. Writing takes place in a single pass of the focused laser beam. In most of these cases one deals with Data Base Management Systems (DBMS). This is useful for companies that make their own ROMs from software they 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.. Also these programs written for execution in one computer cannot be used on another type of computer. Add 1 from carry: 10+1=11. They come highly recommended. To appreciate this, suppose you had an empty disk pack on which you wished to record data. (20 minutes presentation + 5 minutes for The CPU is connected to the main memory by three separate buses. Secondary storage is necessary because memory, or primary storage, can be used only temporarily. It is also easy to see that multiplying and dividing by 2 shifts everything by one column: two in binary is 10, or (1*2^1). (a) Vacuum tubes (b) Capacitors (c) Transistors (d) Integrated circuits, Which one of the following types of computers is commonly used in offices The control unit coordinates and controls all the operations carried out by the The second generation saw the introduction of more complex ALU and CPU, the use of high level languages and provision of system software with the computer. The record storage rooms would have to be enormous. For the sake of simplicity, throw away the remainder. o Digital Camera Used to take electronic pictures of an object. Prepare an oral presentation of approximately 25 min. Starting from zero, we count 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F. At this point there are no more digits, so we add another column. 2. WebEC8552 Computer Architecture and Organization Lecture Notes, Syllabus & Important Questions (Regulation 2017) EC8552 Computer Architecture and Organization.Pdf DOWNLOAD (Including Syllabus, Lecture Notes, 2 Marks & 16 Marks with Year Wise Question Paper Collections) We are very Happy to Provide your all Requirements in a Temporary Result: 01; Carry: 1, Column 2^2: 1+0=1 Add 1 from carry: 1+1=10. They support concurrent users. All the tracks thus encountered, in the same position on each disk surface, comprise a cylinder. Motherboard failures usually show up as second level problems, like "I've replaced the video card and the screen is still dead." C. Characteristics of computers http://www.math.grin.edu/~rebelsky/Courses/152/97F/Readings/student-, L.N.Gumilyov Eurasian National University, Jomo Kenyatta University of Agriculture and Technology, Kwame Nkrumah University of Science and Technology, Introduction to Entrepreneurship (Introduction to Entr), Human Resource, Organizational Behavior, (HR, OB), Bachelor of science in accountancy (150062), FOUNDAMENTALS OF NURSING SCIENCE (NRSG 212), Geometrical Optics and Mechanics (PHY112), Avar Kamps,Makine Mhendislii (46000), Power distribution and utilization (EE-312). Over 100's of millions have been sold, making it the de facto standard. computer to another they have limited storage capacity, generally 1 MB. First generation computers (1946-1956) Output The design of these computers was based on VLSI (very large scale integration) technology, the micro chip technology that gave rise to the smaller computers known as the micro computers in use today. Assembly language is translated into machine code using an assembler before they can be executed. 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 the constituent parts of the system are interconnected and how they ci Ny&V3Otu1gz=} -`iA2(]^,{X+b'Md90sob^V}+^LgaCt4'USr?idz}KiLn[!e8$-$+O;7m%z1+$9]ZumJxC|h$? Main Memory Define computer data storage. There are different types of disk packs, with the number of platters varying by model. For example, if the data bus is 8 bits wide, and each instruction is 16 bits long, then the processor must access the main memory twice during each instruction cycle. 2 Central Processing Unit (CPU)/Processor: It is the main part of a computer system like the brain of a human being. This fact makes it easy to convert between binary and hexadecimal. Unlike competing standards, SCSI is capable of supporting eight devices, or sixteen devices with Wide SCSI. Hybrid Computers: Hybrid computers incorporate the technology of both analog and For example, a typical 4GL command is: A popular 4GL is SQL , which is a database language used to create queries and build database objects. generation saw the introduction of more complex ALU and CPU, the use of high WebSymposium on Computer Architecture (ISCA), 1994 Lecture notes will be available in pdf and powerpoint formats, with 6 per page for pdf for conventinent printing.. (Powerpoint is for instructors who want to give lectures themselves based on CS 252.) D. Hard Drive Failure Troubleshooting, V. Input and output devices and interrupts. The largest power of 2 in 11 is 8, or 2^3. They made use of vacuum tubes to store and process information. general purpose software, integrated packages and software suites. This is even, so we put a 0 in the 8's column. stream You should also refer to the lecture notes available from the textbook website. When the CPU wishes to access a particular memory location, it sends this address to memory on the address bus. (c) Explain the use of registers in the CPU. When we first learned about numbers, we were taught that, in the decimal system, things are organized into columns: such that "H" is the hundreds column, "T" is the tens column, and "O" is the ones column. They were But the DVD will undoubtedly gain a place as the successor to the CD ROM and is playing an important role in the blending of computers and entertainment centers. times per second! interprets the instructions in the program and executes one by one. 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. Data access A concept of using several small disks that work together as a unit is called a redundant array of inexpensive disks, or simply RAID. Each new track and new surface, however, would require movement of the access arms, a relatively slow mechanical process. WebComputer architecture, like other architecture, is the art of determining the needs of the user of a structure and then designing to meet those needs as effectively as possible within economic and technological constraints.
