Four's column: Now we can subtract 1 from 81 to see what remainder we still must place (80). classified and known as super computer. 2 Input Devices (0's and l's). In some disk drives the access arms can be retracted; then the disk pack can be removed from the drive. time was measured in micro-seconds. This is sometimes referred to as direct overwriting and can be repeated several thousand times per disc. The purpose of the control bus is to transmit command , timing and specific status information between system components such as the memory, processor, keyboard input controller VDU output controller and the Disk I/O controller. We begin with a look at the various storage media, including those used for personal computers, and then consider what it takes to get data organized and processed. 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). typing, recording keeping, production of financial statements, drawing, and statistics. Older Zip disks hold 100MB, newer ones hold 250MB and cost $8-$10 a piece (Floppies hold 1.4MB and cost around $2). The system clock generates a continuous sequence of clock pulses to step the control unit through its operation. The tubes consumed a lot of power and generated a lot of heat (overheating). If you cannot divide the binary number evenly into blocks of four digits, add zeros to the left side of the number to make it work. to the C language (part 2/2), Run-time Fuller F., Larson B., Computers: Understanding Technology(Second Edition) In assembly language mnemonic codes are used to develop program for problem solving. Explain the different hardware units of a computer system such as input, The CPU and the RAM are two main components that can be upgraded to increase a computer's speed, though doing this may require replacing the motherboard as well. They have higher main memory capacity, reliable and increased processing power (have the capability of holding more than one set of instructions and operate on them) than the second generation computers. NB: Nowadays most of the general purpose software is being sold as a complete software suites such as Microsoft office or Lotus SmartSuite. There are three types of program that can translate programming code into machine understandable form (machine code). To read the data, the laser scans the disk, and a lens picks up different light reflections from the various spots. Continuing the "CD" analogy, this a lithium battery. Particularly step 3, "filling in the zeros." This computer is not used as a PC in a home neither by a student in a college. In short a COMPILER is: the translator of the source code into computer language. However, this is not the only approach possible.

Kurose,W. Examples operating systems that use command based interface are Ms Dos and Unix. They can be used as servers in companies. Commands tell the computer to do something, like save the file. This is similar to the way a CD-ROM recorder solving constructs, Assembly What we're doing here is finding the largest power of two within the number (2^2=4 is the largest power of 2 in 5), subtracting that from the number (5-4=1), and finding the largest power of 2 in the remainder (2^0=1 is the largest power of 2 in 1). An output device displays information on a screen, creates printed copies or generates sound. o Pointing Devices Pointing devices move some object on the screen and Temporary Result: 1; Carry: 0, Column 2^1: 1+1=10. Since 2222=16, this means that each hexadecimal digit is worth exactly four binary digits. D&T: Erasable Programmable ROM (EPROM): An EPROM is a ROM that can be erased and reprogrammed. Since 81 is odd, a[1]=1. Logical operations it compares two data items to determine whether the This change further decreased the size, heat output and the maintenance complexity of the computers while increasing its speed.

The number 81 in binary would also have a 1 in the 2^0 column. the capacity to hold significantly more data than a 5-1/4 inch diskette. support concurrent users. The class will review fundamental structures in modern microprocessor and computer system architecture design. Tentative topics will include computer organization, instruction set design, memory system design, pipelining, and other techniques to exploit parallelism. Thus, our number is 1001011. For example, 8F in hexadecimal is 10001111 in binary, since 8=1000 and F=1111. 1 Lecture 21: Software Architectures 21-architecture.ppt Author: Steve Easterbrook Created Date: To overcome this limitation, the hexadecimal number system was developed. These computers used transistors after invention of transistors. Micro Channel Architecture (MCA) was introduced by IBM in 1987. Both types of RAM are volatile, meaning that they lose their contents when the power is turned off. (a) Supercomputers (b) Mainframe (c) Mini computer (d) Micro computer. Windows is a Graphical user interface based operating system. The disk in its drive is shown in Figure 3. WebBIT 1101 Computer Architecture complete lecture notes for first years and all - P. Box 342-01000 - Studocu. All 4GLs are designed to reduce programming effort, the time it takes to develop software, and the cost of software development. In most of the Hollywoods movies it is used for animation purposes. Use large scale integration circuits which housed hundreds of transistors and very large IC which are between 200,000 to 400, 000 in one IC. 2022, Assignment 1. 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 chipset is part of the motherboard's logic system and is usually made of two parts --the northbridge and the southbridge. These are devices which are used to store huge information for future use. software. The record storage rooms would have to be enormous. Storage capacity was A little glass window is installed in the top of the Table of Contents. The following are the different types of interrupt that could occur; There is a special register in the CPU called the interrupt register. In most of these cases one deals with Data Base Management Systems (DBMS). When buying a computer the speed of the CD-ROM drive is advertised using an "X" factor, like 12X, or 24X. Thus, the answer is 71. Our running total now stands at a[3]=0, a[2]=0, a[1]=1, and a[0]=1. WebComputer Architecture PPT Instructor Prof. Laxmi N.

Cas a model of computation Digital logic as a model of computation Programmers view of how a computer system works HW designers view of However, the amount of time it takes to access a record is dependent to some extent on the mechanical process involved. Power supplies often fail gradually, giving rise to symptoms that appear to be caused by individual component failure. Instead of using the digits 0-9, we only use 0-1 (again, if we used anything larger it would be like multiplying 2*2^n and getting 2^n+1, which would not fit in the 2^n column. character recognition (OCR) software is needed Video Failure Troubleshooting the lecture -- the notes posted here provide, in some cases, more South bridge -Refers to the Peripheral Bus Controller component of a Pentium chipset, responsible for implementing a PCI-to-ISA bridge function and for managing the ISA bus and all the ports. contains materials that are frequently examined. The data layer is only half as thick as in the CD-ROM. FACE RECOGNITION AND SIMILAR, Structure and Interpretation of Computer Programs, TEXTURE ANALYSIS USING SPECTRAL TRANSFORMS. Made of flexible Mylar, a diskette can record data as magnetized spots on tracks on its surface. For many applications, EAROM has been supplanted by CMOS RAM backed-up by a lithium battery. Knowledge Network of Toyota. As we have already noted, magnetic tape is used primarily for backup purposes. Over 100's of millions have been sold, making it the de facto standard. The sector method is used for diskettes as well as disk packs. -- you are required to read the textbook before (and after) each class. Here we are blurring the line a bit between what "read-only" really means, but remember that this rewriting is done maybe once a year or so, compared to real read-write memory (RAM) where rewriting is done often many times per second! Need sound recording There are many reasons for a slow computer, but upgrading the computer's hardware can help speed it up. Used to put printed pictures and text into a computer. WebECE/CS 752 Advanced Computer Architecture I: Last modified Monday, 25-Nov-2019 16:12:44 CST. Storage capacity was very low i.e. represent and store data in discrete quantities or numbers. next change came after about 1600 years. There is more than one way of physically organizing data on a disk. class. memory. temperature, speed etc. Although the user enter data in decimal or character form, it is converted into binary digits Visual programming allows you to easily envision object-oriented programming class hierarchies and drag icons to assemble program components. drive. D. Types of computers. No optic media can keep up with this. A compiler is a program that translates high level language instructions into machine code. Computers have circuits that can add, subtract, multiply, divide, and do many other things to numbers stored in binary. P.O. processing. Data can also be destroyed if a read/write head encounters even minuscule foreign matter on the disk surface. Introduction to Computer and its components using special equipment (a PROM programmer. Two read/write heads are on each arm, one facing up for the surface above it and one facing down for the surface below it. system that is seen by a machine language (or assembly language) Software: Categories of software, System software, applications software, Optical storage technology is categorized according to its read/write capability. They made use of vacuum tubes to store and process information. Their input /output capabilities were usually limited to the keyboard and or punched card input and printer and or punched cart output. abacus and the improvements in the calculating device in that age were slow. A computer is an electronic device capable of executing instructions, developed Take a look at the images below on the right, as you can see, we have pointed out certain parts of the DIMM memory module and the DIMM slot. Once the commands are entered on the prompt a command line interpreter(CLI) identifies and executes the commands. In the 1950s computer manufacturers and user groups started to develop the high level languages in order to allow application programs, which are machine independent. V. Secondary storage/Backing Storage. The IBM 360 is an example of third generation computers. Once full, a removable hard disk cartridge can be replaced with a fresh one. Two reels are used, a supply reel and a take-up reel. Data on the track is accessed by referring to the surface number, track number, and sector number where the data is stored. Tape now has a limited role because disk has proved the superior storage medium. It is usually necessary to scan some (but not all) of the preceding data. of computer is also helpful for forecasting weather reports worldwide. Central processing unit (CPU) or processor notes posted are a superset of what I will go over during Explain the characteristics of computers and how they are different from The micro chip technology has enabled reduction of size of computers. Hardware To convert the decimal number 75 to binary, we would find the largest power of 2 less than 75, which is 64. and to perform computations on these measurements. It is a blueprint and functional description of requirements and design implementations for the various parts of a computer, focusing largely on the way ()by which the central processing unit (CPU) performs internally and accesses ()addresses in memory. At the end of the chapter the learner shall be able to; The disk cartridges look like a floppy disk, but are slightly bigger in all dimensions. The number 76, for example, takes only two digits to write in decimal, yet takes seven digits to write in binary (1001100). to do something, like save the file. Output devices 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. As in other magnetic media, data is stored as extremely small magnetic spots. To execute an assembly language program it should first be translates into an equivalent machine language program. may be entered into a computer system. Explain the different storage units of a computer such as byte, Kilobyte, Hardware units (Devices) of a computer can be categorized into five units; size though today the term is used to refer to large computers. They are mainly used for presentations.

Special storage locations called registers are included in this circuitry to hold information temporarily while it is being decoded or manipulated. D. Hard Drive Failure Troubleshooting, V. Input and output devices and interrupts. For the sake of simplicity, throw away the remainder. Picture, if you can, how many filing-cabinet drawers would be required to hold the millions of files of, say, tax records kept by the Internal Revenue Service or historical employee records kept by General Motors. Explain the fundamental difference between computer hardware and If we put the 1 in the 2^0 column, we have 162 left, and have to decide how to translate the remaining digits. 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. slower and less costly compared to mainframe computers but more powerful, The technology works like this: A laser hits a layer of metallic material spread over the surface of a disk. With any method of data storage, a backup system a way of storing data in more than one place to protect it from damage and errors is vital. iv. Different industries also use this huge computer for designing their products. During interpretation no object code is produced, and so the program has to be interpreted each time it is to be run. software program. They are known for von Newmans design i.e. L}NoD39C3(xh`4E_(

Almost as intuitive is the number 5: it is obviously 4+1, which is the same as saying [(2*2) +1], or 2^2+1. B. Peripheral Component Interconnect (PCI)-connections for video, sound and, video capture cards, as well as network cards, Integrated Drive Electronics (IDE) -interfaces for the hard drives. Binary is an effective number system for computers because it is easy to implement with digital electronics. They come highly recommended. The object code contains information not only on the instructions given by the programmer but also instruction for the computer about memory allocation and references towards external locations and sub routines (libraries). How data files are stored in secondary storage varies with the types of media and devices you are using. When we talk about troubleshooting video failures, we're usually talking about no image at all on the screen. In addition, the EISA can accommodate a 16-bit ISA card in the first row. The motherboard's main job is to hold the computer's microprocessor chip and let everything else connect to it. % Everything that runs the computer or enhances its performance is either part of the motherboard or plugs into it via a slot or port. Flash memory is a type of EEPROM chip, which stands for Electronically Erasable Programmable Read Only Memory. Operators, Von the most flexible type of ROM, and is now commonly used for holding BIOS Making this algorithm a bit more formal gives us: This algorithm is a bit awkward. The most prominent optical technology is the CD-ROM, for compact disk read-only memory. Winchester disk assemblies are put together in clean rooms so even microscopic dust particles do not get on the disk surface. We're left with 1, which goes in 2^0, and we subtract one to get zero. WebLecture notes Chapters 1-3, 5-12 The CMU ICS+ coursethat covers everything in CS:APP3e except Chapter 4 (Processor Architecture). does not cover memory design in any depth and I will provide detailed The methods we will consider here are the sector method and the cylinder method. This computer is commonly used in big hospitals, air line reservations written and quite useful -- they were written by the instructor for A CD-RW allows you to read, write, erase and write again. Explain how the different units of a computer interact witch each other to The processor also stores the instructions being currently executed into the main memory. based on algorithms stored in its memory, to process data fed to it and produce Storage technologies at all levels of the storage hierarchy can be differentiated by evaluating certain core characteristics as well as measuring characteristics specific to a particular implementation. C.

Electrically Erasable Programmable ROM (EEPROM): The next level of WebComputer architecture is the science and art of selecting and interconnecting hardware components to create a computer that meets functional, performance and cost goals. The term mainframe was mainly used for earliest computers as they were big in Most mainframe computers have 32-bit words. Chapter 2- Basic Organization of a Computer. Software is simply set of instructions that cause a computer to perform one or more tasks. i. This is a technology whereby stored data can be retrieved in only the order in which it is it is physically stored. Some of the other standards include: The socket for the microprocessor determines what kind of Central Processing Unit (CPU) the motherboard uses.
