I. 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. At the beginning of each fetch-execute cycle, the interrupt register is checked. Since 0011=3 and 0101=5, the corresponding hexadecimal number is 35. http://www.math.grin.edu/~rebelsky/Courses/152/97F/Readings/student-binary, Answers 1 255 2. a) 3 b) 6 3. a) 110010 4. a) 1011 5 a) 13, c) 10 d) 65 b) 1001011 d) 1000011c) 11111010. Examples: What would the binary number 1011 be in decimal notation? WebComputer hardware components can generally be broken down into three categories: Processing Processing components are responsible for actually carrying out actions in Their input /output capabilities were usually limited to the keyboard and or punched card input and printer and or punched cart output. 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). A little glass window is installed in the top of the 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. read the textbook and, preferably, the posted notes before coming to They are A hard disk is a metal platter coated with magnetic oxide that can be magnetized to represent data. represent and store data in discrete quantities or numbers. Continue counting once again: 20, 21, 22, , 29, 2A, 2B, 2D, 2E, 2F, 30, 31, 32, , 3E, 3F, 40, 41, 42, 99, 9A, 9B, 9C, 9D, 9E, 9F, A0, A1, A2, F9, FA, FB, FC, FD, FE, FF, 100, 101, 102, . Watch the pattern of numbers and try to relate this to the way you count in decimal or binary. Personal computer users have the option of purchasing their own tape backup system, to be used on a regular basis for copying all data from hard disk to a high-capacity tape. Programming: I/O, Traps and Today, motherboards typically boast a wide variety of built-in features, and they directly affect a computer's capabilities and potential for upgrades. Need sound recording What happens when, for example, a key on the keyboard is pressed, thus generating an interrupt? Multiplication in the binary system works the same way as in the decimal system: Note that multiplying by two is extremely easy. These are: An assembler is a program that translates assembly code into machine code. A network operating system is required when a number of computers are connected together to form a network. Motherboard failures usually show up as second level problems, like "I've replaced the video card and the screen is still dead." Some modern Intel Core i3, i5 and i7 processor brands are split into desktop and laptop (or mobile) processors. 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. C. Interrupts; types of interrupt, interrupt priorities, interrupt handler. Output devices The only way a number can be odd is if it has a 1 in the 2^0 column, because all powers of two greater than 0 are even numbers (2, 4, 8, 16). To provide an in-depth presentation of computer hardware and software with contains materials that are frequently examined. programs that are static (not changing often) and mass-produced. Making this algorithm a bit more formal gives us: This algorithm is a bit awkward. In 1998 Macintosh introduced its new computer, the IMAC, without a floppy disk drive. 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.. Disk data is quite reliable, especially within a sealed module. The CPU is connected to the main memory by three separate buses. V. Secondary storage/Backing Storage. Cache memory Diskettes became popular along with the personal computer. The sector method is used for diskettes as well as disk packs. variables, Implementation of functions, Dynamic P. Box 342-01000 Thika Therefore, we should rewrite it such that we ascertain the value of each column individually, putting in 0's and 1's as we go: Now that we have an algorithm, we can use it to convert numbers from decimal to binary relatively painlessly. Rewriting an EAROM is intended to be an A set of programs associated with the operation of a computer. The take-up reel always stays with the magnetic tape unit. While information retrieval is faster than from a floppy disk, it is still not as fast as from the hard drive. This is a technology whereby stored data can be retrieved in only the order in which it is it is physically stored. Thus, the answer is 71. Control lines are used to ensure that access to and use of the data and address buses by the different components of the system does not lead to conflict. The organization in this case is vertical. WebLecture 1 : Evolution of Computer Systems: Download Verified; 2: Lecture 2 : Basic Operation of a Computer: Download Verified; 3: Lecture 3 : Memory Addressing and This bus is bi-directional meaning that signals can be carried in both directions. class. Here is a link to some online notes that I found to be well The first motherboards held very few actual components. To understand binary numbers, begin by recalling elementary school math. The interrupt signal is sent along a control line to the processor, and the currently executing program is suspended while control is passed to an interrupt service routine. To quote many a computer user, "I just couldn't envision how I could use all that disk space. Input Devices The processor and main memory of a PC are commonly held on a single board called a mother board. Motherboards have come a long way in the last twenty years. The program given below shows assembly language program to add two numbers A & B. 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. Begin with one-bit binary addition: 1+1 carries us into the next column. technology is analogous to a reusable CD-RW. lecture notes available from the. Fuller F., Larson B., Computers: Understanding Technology (Second Edition), Assessment: Examination -70%: Coursework -30%. C. Motherboard and CPU Troubleshooting Tracks within a cylinder are numbered according to this vertical perspective: A 20-surface disk pack contains cylinder tracks numbered 0 through 19, top to bottom. In assembly language mnemonic codes are used to develop program for problem solving. Software is simply set of instructions that cause a computer to perform one or more tasks. Hard disks for personal computers are 5-1/4 inch or 3-1/2 inch disks in sealed modules and even gigabytes are not unusual. (a) Vacuum tubes (b) Capacitors (c) Transistors (d) Integrated circuits, Which one of the following types of computers is commonly used in offices 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. consumed a lot of power and generated a lot of heat (overheating). 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.

Microsoft, Borland, IBM, and other companies make 5GL visual programming products for developing applications in Java, for example. Performance and Code State three types of computer buses. Organization: Cache, Main Memory, Printout is permanent Intro to LC3, Low-level The easy cases to diagnose are those where the monitor or LCD isn't powering up properly, or the PC not powering up. Computer Organization and Architecture lecture notes include computer organization and architecture handwritten notes, computer organization and architecture book, computer organization and architecture courses, computer organization and architecture syllabus, computer organization and architecture 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). Neumann Architecture Model and D. Types of computers. does not cover memory design in any depth and I will provide detailed write, because when they change their code they can create new PROMs without seconds. really means, but remember that this rewriting is done maybe once a year or so. Instruction set architecture System organization (processor, memory, I/O) Micro-architecture Learn methods of evaluating performance Metrics Benchmarks Learn how to make systems go fast Pipelining, caching Parallelism Learn how to make systems less power hungry (maybe) Video card failure isn't uncommon, and video cards can lose their contact with the motherboard, especially early AGP adapters which frequently popped out of their slot. Web6.823 is a course in the department's "Computer Systems and Architecture" concentration. Chapter 3- Instruction EAROM Bus size means the number of bits that can be transmitted together. In fact, flash memory is known as a solid state storage device, meaning there are no moving parts --everything is electronic instead of mechanical. chapters. Software: Categories of software, System software, applications software, WebTextbook: Computer Architecture: A Quantitative Approach, Third Edition, John L. Hennessy and David A. Patterson, ISBN 1-55860-596-7A Course Readings Lecture 1: iv. Erasable Programmable ROM (EPROM): An EPROM is a ROM that can be erased and reprogrammed. D. Buses; control bus, data bus, Address Bus, SCSI, EISA, MCA, IV. Video Failure Troubleshooting When buying a computer the speed of the CD-ROM drive is advertised using an "X" factor, like 12X, or 24X. In a command based interface the user enters commands through an interactive terminal. RDRAM (Rambus DRAM) involves a new memory design that achieves a higher data transfer speeds but it is expensive to manufacture. 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. (b) List four of the conditions an ALU tests for. powerpoint format) I will post detailed notes that will go into blueprint and functional description of requirements and design Fuller F., Larson B., Computers: Understanding Technology(Second Edition) 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. It is the smallest of the three computers. Similarly, multiplying by 2 shifts in the other direction: {a[n]*2^n + a[n-1]*2^(n-1) + + a[1]*2^1 + a[0]*2^0}/2. can do some action Mouse is a common pointing device They can be linked to smaller o Voice input device- A computer I/O device in which vocal commands software program.

This requires a transmission rate of 4692 bits per second. (a) Vacuum tubes (b) Capacitors (c) Transistors (d) Integrated circuits, The third generation of computers used 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. Particularly step 3, "filling in the zeros." They support concurrent users. Tape now has a limited role because disk has proved the superior storage medium. The EISA bus is found on Intel 80386, 80486 and early Pentium computers. Instead of typing a command or file name, selection is achieved by moving a pointer with a mouse and clicking a mouse button. 18-213 18-240. They can be linked to smaller computers and handle hundreds of users they are also used in space exploitation. The width of the data bus is a key factor in determining overall system performance. Graphical user interface has some disadvantages such as. They can be used as servers in companies. solving constructs, Assembly 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. 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. There is more than one way of physically organizing data on a disk. The lecture Explain the evolution of computing technology and the technological general purpose software, integrated packages and software suites. Over 100's of millions have been sold, making it the de facto standard. Put 1 in the 2^1 column, 0 in 2^2, and subtract 2 from 3. Chapter 2- Basic Organization of a Computer. The largest power of 2 in 11 is 8, or 2^3. based on algorithms stored in its memory, to process data fed to it and produce Take the number 163. 500,000 physical elements e. transistors, capacities, diodes etc per Each peripheral device operates in a different way and hence these devices cannot be connected directly to the processor. 10 INPUT A,B 20 LET C=A+B 30 PRINT C 40 END, To read the value of A&B A&B are added and result is stored in C Print the value of C Stop execution. ii. 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. We saved magnetic tape storage for last because it has taken a subordinate role in storage technology. A single bit alone cannot represent a number, letters or special characters, to represent information; bits are combined into groups of eight. 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). Read-only media are recorded on by the manufacturer and can be read from but not written to by the user. The definition from the Merriam-Webster Dictionary : "one that computes; specifically : a programmable electronic device that can store, The fact that a disk is circular presents a problem: The distances around the tracks on the outside of the disk are greater than that of the tracks or the inside. 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. 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). category was ENIAC (electronic discrete variable automatic computer) and later within a computing system such as: Objectives 2kb and speed of processing was also very low. The transistor is smaller cheaper and produced less heat than vacuum tubes and consumed less power. the required results faster than human beings. time was measured in micro-seconds. They are of advanced technology i.e. Explain the different hardware units of a computer system such as input, They are very large in size and use multiple processors and superior technology.

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 diagram above shows how the units interact with each other in the processing of data. (2mks) (b). The first calculating device, which was used 2000 years ago was called abacus and the improvements in the calculating device in that age were slow. Explain how information is stored in a computer by "flashing", this refers to reprogramming the BIOS EEPROM with a special 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. The system clock generates a continuous sequence of clock pulses to step the control unit through its operation. The width of an address bus, along with the size of addressable memory elements, determines how much memory can be accessed. the most flexible type of ROM, and is now commonly used for holding BIOS The MCA bus offered several additional features over the ISA such as a 32-bit bus (although there was also a 16-bit bus), ran at 10MHz, automatically configure cards (similar to what Plug and Play is today), and bus mastering for greater efficiency. The disk cartridges look like a floppy disk, but are slightly bigger in all dimensions. The data layer is only half as thick as in the CD-ROM. c l oc k , registers (e) Computers have evolved through many generations over the explain the five generations the computers have evolved through. C. Characteristics of computers Record the 0 in the ones column, and carry the 1 to the twos column to get an answer of "10." Super computers are biggest in size, the most expensive in price than any other is classified and known as super computer. This process continues until we have a remainder of 0. They are expensive to install. to the C language (part 2/2), Run-time vdu controller. Software At present, computer users do not write programs using machine language.

Similarly, the statement a[n-1]*2^(n-1) + a[n-2]*2^(n-2) + + a[1]*2^0 has a power of two removed. @@TTA drive. Subtract 8 from 11 to get 3. first one is smaller than, equal to or greater than the second item. Explain the characteristics of computers and how they are different from to be reprogrammed again. Computers cannot do any useful work without instructions from software; thus a combination of software and hardware (the computer) is necessary to do any computerized work. They made use of vacuum tubes to store and process information. Temporary Result: 01; Carry: 1, Column 2^2: 1+0=1 Add 1 from carry: 1+1=10. Four's column: Now we can subtract 1 from 81 to see what remainder we still must place (80). This is a technology that allows a computer to immediately locate and retrieve a program, information or data. The record storage rooms would have to be enormous. This presentation is available free for non-commercial use with attribution under a creative Once full, a removable hard disk cartridge can be replaced with a fresh one. At the end of the chapter the learner shall be able to; classified and known as super computer. Email: info@mku.ac If we put the 1 in the 2^0 column, we have 162 left, and have to decide how to translate the remaining digits. Temporary Result: 001; Carry: 1, Column 2^3: 1+1=10. It interprets the instructions in the program and executes one by one. Since these programs use only '0's and '1's it will be very difficult for developing programs for complex problem solving. This gives us the rightmost digit as a starting point. this unit. High level language permits the user to use understandable codes using the language structure. This places the data in diagonal bands that run across the tape rather than down its length. abacus and the improvements in the calculating device in that age were slow. Such a disk cannot, obviously, be used for your files, but manufacturers can use it to supply software. This generation marked the origin of mini computers in use today. ALL, The processor can read and write into the secondary storage devices. This is significant data insurance. In most of the Hollywoods movies it is used for animation purposes. Visual programming allows you to easily envision object-oriented programming class hierarchies and drag icons to assemble program components. They are smaller than the main frame but bigger than microcomputers. A monitor, printer, and speakers are examples of output devices. may be entered into a computer system. They are usually called personal computers since they are designed to be used by individuals. 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. NB: Nowadays most of the general purpose software is being sold as a complete software suites such as Microsoft office or Lotus SmartSuite. (a) Name the two major components of the Central Processing Unit and briefly describe what each does. support concurrent users. The data in that memory location is then returned to the CPU on via the data bus. In most of these cases one deals with Data Base Management Systems (DBMS). A disk drive is a machine that allows data to be read from a disk or written on a disk. ()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. The stored bits are usually retrieved from computers memory for manipulation by the processor. I. Direct-access storage allows you to access the 125th record without first having to read the 124 records in front of it. Zone recording involves dividing a disk into zones to take advantage of the storage available on all tracks, by assigning more sectors to tracks in outer zones than to those in inner zones. 2. The chipset is part of the motherboard's logic system and is usually made of two parts --the northbridge and the southbridge. Interrupts are therefore assigned priorities so that when two interrupts are received simultaneously, the one with the highest priority is dealt with first. them on the computer. next change came after about 1600 years. You will see that it is the same procedure, but with sixteen digits instead of 10 or 2. increased. This opens the possibility to write data in two layers. (20 minutes presentation + 5 minutes for To provide an in-depth presentation of computer hardware and software with more emphasis on the more technical aspects of computing such as troubleshooting and upgrading computers. xH2Z@Qh>$p+![r5V28U<>hc`Ko3e7F^(CRz.]kA/()U&JxQ*r"?Da:)oW6LW8it^0!m OzDH Hard disks come in a variety of sizes.

The outer gold layer is semi transparent, to allow reading of the underlying silver layer. discuss the detailed working and components of these computers in subsequent sections of They are used to enter WebUniversity of Toronto Department of Computer Science 2004-5 Steve Easterbrook. Temporary Result: 1; Carry: 0, Column 2^1: 1+1=10. They can be used as servers in companies. 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. They are of advanced technology i. the micro era based on large scale implemented in a single piece of silicon device known as a computer chip. the lecture -- the notes posted here provide, in some cases, more A CD-R is a one time recordable compact disc. In order to synchronise the various steps carried out during the fetch-execute cycle, all the processors have an internal clock which generates regularly timed pulses. Temporary Result: 11 New D=40 D does not equal 0, so we repeat step 2. The term mainframe was mainly used for earliest computers as they were big in size though today the term is used to refer to large computers. A key advantage of a tape backup system is that it can copy the entire hard disk in minutes, saving you the trouble of swapping diskettes in and out of the machine. This document 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. image into dots that the computer can understand .To scan text, optical stream software Number Word size also determines the speed of the computer. You are required to Following this, the changes were I/O controllers are available which can operate both input and output transfers of bits, e.g. Web: mku.ac. software. Data files may be stored on or in sequential-access storage, direct-access storage, or random-access storage. refer to the floppy disk controller. Microcomputers can be a desktop, laptop, notebooks, or even palmtop. Hard disks use magnetism, while computer memory uses electric charges stored in tiny capacitors to indicate "on" or "off.". Assembly language is designed mainly to replace each machine code with and understandable mnemonic code. Explain the different storage units of a computer such as byte, Kilobyte, Hardware units (Devices) of a computer can be categorized into five units; Microarchitecture, also known as Computer organization is a lower level, Static RAM does not need to be refreshed, which makes it faster; but it is also more expensive than dynamic RAM. For the sake of simplicity, throw away the remainder. For personal computer users, an easy and inexpensive way to back up a hard disk file is to simply copy it to a diskette whenever it is updated.
