iv. Data can be obtained quickly from anywhere on the media. Pages 4-. This computer is commonly used in big hospitals, air line reservations companies, and many other huge companies prefer mainframe because of its capability of retrieving data on a huge basis. this unit. The small circuitry that resulted improved the processing speed i.e. ()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. It They 10100011=(1*2^0)+(1*2^1)+(1*2^5)+(1*2^7)=1+2+32+128= 163. Motherboards have come a long way in the last twenty years. Microarchitecture, also known as Computer organization is a lower level, 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. Rewriting an EAROM is intended to be an Today, motherboards typically boast a wide variety of built-in features, and they directly affect a computer's capabilities and potential for upgrades. Such a disk cannot, obviously, be used for your files, but manufacturers can use it to supply software. Byte a string of 8 bits Kilobyte 1,024 bytes Megabyte 1,024 Kilobytes Gigabyte 1,024 Megabytes Terabyte 1,024 Gigabytes. In some disk drives the access arms can be retracted; then the disk pack can be removed from the drive. A monitor, printer, and speakers are examples of output devices. The IBM 360 is an example of third generation computers. Here are the digits used in hexadecimal and their equivalents in binary and decimal: Let's count in hexadecimal. Performance and Code came UNIVAC (universal automatic computers). the number 193 is really {(1*10^2)+(9*10^1)+(3*10^0)}. erasability is the EEPROM , which can be erased under software control. Begin by thinking of a few examples. The mechanism for reading or writing data on a disk is an access arm; it moves a read/write head into position over a particular track. Binary is an effective number system for computers because it is easy to implement with digital electronics. Since 81 is odd, a[1]=1. CHAPTER 2: BASIC HARDWARE UNITS OF A COMPUTER 14, CENTRAL PROCESSING UNIT (CPU)/PROCESSOR: 16, HOW INFORMATION IS STORED IN COMPUTERS 21, CHAPTER FIVE: INPUT AND OUTPUT DEVICES AND INTERRUPTS 39, THIRD GENERATION HIGH LEVEL LANGUAGES 43, CHAPTER EIGHT: DISKS AND SECONDARY STORAGE 55, CHAPTER NINE: HOW TO UPGRADE A SLOW COMPUTER 67, CHAPTER TEN: INTRODUCTION TO BINARY NUMBERS 70, BASIC CONCEPTS BEHIND THE BINARY SYSTEM 71, ANOTHER ALGORITHM FOR CONVERTING DECIMAL TO BINARY 77. When you play movies, your hardware (MPEG decoder. capability of retrieving data on a huge basis. increased. Unlike competing standards, SCSI is capable of supporting eight devices, or sixteen devices with Wide SCSI. In addition, the EISA can accommodate a 16-bit ISA card in the first row. A way to organize data on a disk pack is the cylinder method. Put 1 in the 2^1 column, 0 in 2^2, and subtract 2 from 3. When the human race started doing some trade, it felt a need for a calculating We're left with 1, which goes in 2^0, and we subtract one to get zero. The purpose is to reduce the time it takes to move the access arms of a disk pack into position. PROM, but it does require the erasing light. 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). Saving and retrieving information from a floppy disk is slower than on a hard There are three types of program that can translate programming code into machine understandable form (machine code). Following this, the changes were The highest-capacity tape is the digital audio tape, or DAT, which uses a different method of recording data. to the C language (part 1/2), Introduction To appreciate this, suppose you had an empty disk pack on which you wished to record data. At the beginning of each fetch-execute cycle, the interrupt register is checked. This requires a transmission rate of 4692 bits per second. I/O controllers are available which can operate both input and output transfers of bits, e.g. If I had to choose one part to blame the majority of intermittent failures in cheap PC's on, it would be the power supply. Box 342-01000 Thika info@mku.ac.ke Email: www.mku.ac.ke Web: Instructional Manual for BBIT Distance Learning. @@TTA The two components (hardware, software) will be discussed later in other The CPU of a Micro computers This is inflexible and so regular ROMs are only used generally for programs that are static (not changing often) and mass-produced. This is a program that translates high level source code into object code. give the user output In order to execute a high-level language program, it should be translated into a machine language either using a compiler or interpreter. A set of programs associated with the operation of a computer. It acts as an intermediate store between the CPU and Neumann Architecture Model and List three common input devices (excluding keyboard and mouse), giving one advantage and one disadvantage for each, together with an example of how each could be used in the retail industry. Large computers have dozens or ever hundreds of disk drives. refer to the In fact, programming a PROM is also called burning, just like burning a CD-R, and it is comparable in terms of its flexibility. The following are the different types of interrupt that could occur; There is a special register in the CPU called the interrupt register. Web6.823 is a course in the department's "Computer Systems and Architecture" concentration. Please note the direction of the arrows as it depicts the flow of the data and instructions. Topics may include: instruction set design; processor micro-architecture and Course Info Instructors computational machines. Temporary Result: 001; Carry: 1, Column 2^3: 1+1=10. P. Box 342-01000 Thika Binary addition works on the same principle, but the numerals are different. The chipset is part of the motherboard's logic system and is usually made of two parts --the northbridge and the southbridge. Most 4GLs are used to access databases. The interpreter translates one line a time and then executes it. This is even, so we put a 0 in the 8's column. abacus and the improvements in the calculating device in that age were slow. The first in the Windows series was Windows 3.11 and the latest being Windows Vista. Control signals are sent along the control bus. No optic media can keep up with this. humans. Stack and Allocation of C WebLecture notes of Prof David Brooks could also be referred. EAROM It may also be defined as the science and art of selecting and interconnecting A. Other controllers operate in one direction only, either as an input controller, e.g. to do something, like save the file. It controls and monitors the running of application programs. ROM package, through which you can actually see the chip that holds the This document should be seasone Computer Architecture and Assembly Language Programming, Computer Organization and Design 4th Edition Solution, Comporg 6 sol2 - Solution manual for the second Chapter of the Computer Architecture, CS401 Quiz 1 Solution by MCS of Virtuallians. A set of programs associated with the operation of a computer. software program. For example, a transistor with five volts would be considered "on", while a transistor with no voltage would be considered "off." Many users, therefore, make later adjustments like adding a removable hard disk cartridge to accommodate expanding storage needs. and data so that it will be very fast to retrieve them again. window for a specified period of time, which will erase the EPROM and allow it These suites offer four or more software products packaged together at a much lower price than buying the packages separately. First machine in this data .They are physically very large in size with very high capacity of main Picture Window theme. Decode translate the program instruction into commands that the to be reprogrammed again. 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. 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. ()Microarchitecture, also known as Computer organization is a lower level, more concrete and detailed, description of the system that involves how the constituent parts of the system are interconnected and how they interoperate in order to implement the ISA. When you start troubleshooting a dead computer, never ignore the possibility that the AC power to the PC's power supply is at fault. They are more susceptible to physical damage and viruses than the hard drive. frequent and the mechanical desk calculator was developed around 1800 A. Assembly language is designed mainly to replace each machine code with and understandable mnemonic code. With IC you can house thousands of transistors in one IC. The transistor is smaller cheaper and produced less heat than vacuum tubes and consumed less power. ntz0_u.E5Yo!& peripherals can be attached to them. Software: Categories of software, System software, applications software, 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). B. Our running total now stands at a[3]=0, a[2]=0, a[1]=1, and a[0]=1. The number 76, for example, takes only two digits to write in decimal, yet takes seven digits to write in binary (1001100). 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 most flexible type of ROM, and is now commonly used for holding BIOS As in other magnetic media, data is stored as extremely small magnetic spots. One idea is to "shift" them. Table of Contents. I. The control unit operates by repeating three operations which are: The cycle (input -processing -output) would not be possible without a holding place for the instructions and data that the processors (CPU) can easily reach. 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. Magnetic tape looks like the tape used in music cassettes plastic tape with a magnetic coating. This computer is not used as a PC in a home neither by a student in a C. Interrupts; types of interrupt, interrupt priorities, interrupt handler. (0's and l's). They can be used as servers in companies. Minicomputers Memory used includes magnetic disc and optical disc. The first calculating device, which was used 2000 years ago was called 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. The largest power of 2 in 11 is 8, or 2^3. 2 Input Devices versions, like the CD-ROM's. IV. The processor also stores the instructions being currently executed into the main memory. Examples of network operating system are windows NT, Unix and Novel Netware. Also note that a1 is essentially "remultiplied" by two just by putting it in front of a[0], so it is automatically fit into the correct column. to the C language (part 2/2), Run-time Hard Drive: Microsoft, Borland, IBM, and other companies make 5GL visual programming products for developing applications in Java, for example. Storage capacity was very low i.e. may be entered into a computer system. (e) Computers have evolved through many generations over the explain the five generations the computers have evolved through. taken by a digital camera can be used directly by a computer Removable disk storage units were. First machine in this category was ENIAC (electronic discrete variable automatic computer) and later came UNIVAC (universal automatic computers). Data on the track is accessed by referring to the surface number, track number, and sector number where the data is stored. Electrically Alterable Read-Only Memory(EAROMs) can be modified a bit at a time, but writing is a slow process and uses non-standard voltages (usually higher voltages around 12 volts). contains materials that are frequently examined. Chapter 2- Basic Organization of a Computer. The organization in this case is vertical. However, only one read/write head can operate at any one time. When data is being entered, heat from the laser produces tiny spots on the disk surface. The system unit is the unit that houses the processing unit (processor), memory, the input output controllers and the buses. We saved magnetic tape storage for last because it has taken a subordinate role in storage technology. The process is the same for multiple-bit binary numbers: Column 2^0: 0+1=1. I. Explain the evolution of computing technology and the technological The decimal number "2" is written in binary notation as "10" (1*2^1)+(0*2^0). II. Typically the clock pulse rate in 2000 is around 500 megahertz (million cycles per second). To read the data, the laser scans the disk, and a lens picks up different light reflections from the various spots. These computers were mostly It is the smallest of the three computers. State and explain any five characteristics of storage. for instance, is an organizational issue that generally has nothing to do The tubes They are very large in size and use multiple processors and superior technology. In fact, flash memory is known as a solid state storage device, meaning there are no moving parts --everything is electronic instead of mechanical. 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 processor has the following functions: The control unit coordinates and controls all the operations carried out by the computer. Logical operations it compares two data items to determine whether the Looking at this in columns. FACE RECOGNITION AND SIMILAR, Structure and Interpretation of Computer Programs, TEXTURE ANALYSIS USING SPECTRAL TRANSFORMS. 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. 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. (10mks), Mechanics of Materials (Russell C. Hibbeler; S. C.

Older Zip disks hold 100MB, newer ones hold 250MB and cost $8-$10 a piece (Floppies hold 1.4MB and cost around $2). A program must tell the computer each of a set of tasks to perform, in a framework of logic, such that the computer knows exactly what to do and when to do it. )wG-$b!vQs@K%quHPg$*^SQ2W9DmwC~#p2Yq$ 6QY >.Se:;r,Cfmw>?o"Nf=n=EV-$k_yBpR!lde])Y^o$,"*Tt *ieHqnUHHq 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. The cylinder method, then, means all tracks of a certain cylinder on a disk pack are lined up one beneath the other, and all the vertical tracks of one cylinder are accessible by the read/write heads with one positioning of the access arms mechanism. Super computers are biggest in size, the most expensive in price than any other is classified and known as super computer. The processor contains the control unit and the arithmetic/logic unit(ALU) and the system clock. Two reels are used, a supply reel and a take-up reel. In a disk pack all disks rotate at the same time although only one disk is being read or written on at any one time. 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. Removable disk storage units were developed for use on these machines. 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). Made of flexible Mylar, a diskette can record data as magnetized spots on tracks on its surface. Recording the data vertically, on the other hand, substantially reduces access arm movement. A mainframe is another giant computer after the super computer and can also process millions of instruction per second and capable of accessing billions of data .They are physically very large in size with very high capacity of main memory. When you store a file on tape, the 125th record cannot be read until the 124 records in front of it are read. 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. 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. microcomputer is called a microprocessor. The technology works like this: A laser hits a layer of metallic material spread over the surface of a disk. Using a method called helical scan recording, DAT wraps around a rotating read/write head that spins vertically as it moves. 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.) It is the main part of a computer system like the brain of a human being. Consequently, the primary role of tape today is as an inexpensive backup medium. Hexadecimal is more compact than binary but is still based on the digital nature of computers. The following program written in BASIC language is to add two given numbers. Electrically Erasable Programmable ROM (EEPROM): The next level of erasability is the EEPROM, which can be erased under software control. AxgyL@0#jE:3tBP20zivoKJ]2w\$wkNIkyDXQwsACvc; hq W j Most disk packs, however, combine the disks, access arms, and read/write heads in a sealed module called a Winchester disk. Explain the characteristics of computers and how they are different from This method produces high density and faster access to data. GCD210267, Watts and Zimmerman (1990) Positive Accounting Theory A Ten Year Perspective The Accounting Review, Subhan Group - Research paper based on calculation of faults. Now we need to do the remaining digits. chapters. The registers shown in the block diagram above, which represents a typical computer, each have a specific purpose, which is described below. Obviously this is much more useful than a regular Cache memory is a type of very fast memory that is used to improve the speed of a 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. lecture notes available from the. These two "bridges" connect the CPU to other parts of the computer. Floppy Disk: Floppy disks allow information to be transported easily from one computer to another they have limited storage capacity, generally 1.44 MB. Subroutines, Solution to Vector Inner (Dot) C. Characteristics of computers The normal number system we use is called the decimal or the denary number system. 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. The programs written in assembly language are also machine dependent. In Fig 1.2, the notches we have marked as A, are used for the ejector clip on the DIMM slot (see later). Chapter 1- Fundamentals of Computer Design. 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). For example, putting ten in the 10^0 column is impossible, so we put a 1 in the 10^1 column, and a 0 in the 10^0 column, thus using two columns. 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. the way by which the central processing unit (CPU) performs internally using special equipment (a PROM programmer. In our vertical notation. the capacity to hold significantly more data than a 5-1/4 inch diskette. An interrupt is a signal from some device or source seeking the attention of the processor. Zip disks are a great way to store large files and software programs. Extended Industry Standard Architecture (EISA) also known as Extended ISA, EISA is a standard first announced in September of 1988 for IBM and IBM compatible computers to compete with the IBM MCA bus. We can start at the right, rather than the left. Data files may be stored on or in sequential-access storage, direct-access storage, or random-access storage. Writing takes place in a single pass of the focused laser beam. Execute cause the instruction to be executed. size IC, hence the size reduced. Ch24 - Chapter 24 solution for Intermediate Accounting by Donald E. Kieso, Jerry J. HCA16ge Ch11 SM - Summary Intermediate Accounting, Suh, Y. Since 11 is greater than 10, a one is put into the 10's column (carried), and a 1 is recorded in the one's column of the sum. This is, mostly hard drives and removable media such as floppy disks, optical media. ROM: A mask programmed read only memory that can be only be produced by These computers were mostly computational machines. A binary digit (1 or 0) is known as a BInary digiT which in short is a bit. It has a grid of columns and rows with a cell that has two transistors at each intersection. within a computing system such as: Objectives erased and reprogrammed. Writing and understanding programs in assembly language is easier than that of machine language. Although a hard disk is an extremely reliable device, a hard disk drive is subject to electromechanical failures that cause loss of data. x[r+&YU@lJSvB%d#QTD[/\{g\\S The drive sells for around $80-$125. There are several specific form factors that most PC motherboards use so that they can all fit in standard cases. monitor, Keyboard, Mouse, system unit etc. A. 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. III. III. Many cartridges and cassettes have the supply and take-up reels built into the same case. In most of these cases one deals with Data Base Management Systems (DBMS). 2. The movies are made in two formats, each with their own coding. This computer is commonly used in big hospitals, air line reservations Storage capacity is unquestionably one of the most valuable assets of the computer. WebCS 135: Computer Architecture I Fall 2010 Lecture Notes. Ultraviolet light of a specific frequency can be shined through this window for a specified period of time, which will erase the EPROM and allow it to be reprogrammed again. And, the access time is independent of the storage location. Can hold up to 700MB of information. The speed of these machines was described in milliseconds (1/1000 of a second). This fact makes it easy to convert between binary and hexadecimal. The processor contains the control unit and the arithmetic/logic unit(ALU). Memory size expanded up to several MB and speed was 10 times faster. They are mainly used for presentations. The processor communicates and controls a peripheral device through an I/O or device controller. consumed a lot of power and generated a lot of heat (overheating). When buying a computer the speed of the CD-ROM drive is advertised using an "X" factor, like 12X, or 24X. Purpose of the course 9 The DVD is a flat disk, the size of a CD -4.7 inches diameter and .05 inches thick. In assembly language mnemonic codes are used to develop program for problem solving. Only an interrupt with a higher priority is allowed to interrupt the servicing of another. Reduce the bandwidth required of the large memory Processor Memory The stored bits are usually retrieved from computers memory for manipulation by the processor. 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. What happens when, for example, a key on the keyboard is pressed, thus generating an interrupt? Graphical user interface has some disadvantages such as. Personal computer users, who never seem to have enough hard disk storage space, may turn to a removable hard disk cartridge. 3. In decimal form, 1+1=2. The processor and main memory of a PC are commonly held on a single board called a mother board. We know that: and so on. general purpose software, integrated packages and software suites. Web1 cache.1 361 Computer Architecture Lecture 14: Cache Memory cache.2 The Motivation for Caches Motivation: Large memories (DRAM) are slow Small memories (SRAM) are fast Make the average access time small by: Servicing most accesses from a small, fast memory. To understand binary numbers, begin by recalling elementary school math. The most prominent optical technology is the CD-ROM, for compact disk read-only memory. Take the number 163. The definition from the Merriam-Webster Dictionary : "one that computes; specifically : a programmable electronic device that can store, o Speakers Used to output sound You are required to A given amount of data that takes up 1 inch of a track on the inside of a disk might be spread over several inches on a track near the outside of a disk.
