Different industries also use this huge computer for designing their products. 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. A bit is used to represent information in the computer. read the textbook and, preferably, the posted notes before coming to Web6.823 is a course in the department's "Computer Systems and Architecture" concentration. 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. Assembly language is translated into machine code using an assembler before they can be executed. When the CPU wishes to access a particular memory location, it sends this address to memory on the address bus. 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.

At the end of the chapter the learner shall be able to; the micro computers are usually described as PCs or stand alone or desktop computers because they were designed primarily to serve single person at a time. A little glass window is installed in the top of the ROM package, through which you can actually see the chip that holds the memory. Super computers are biggest in size, the most expensive in price than any other is 2kb and speed of processing was also very low. 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. A. consumed a lot of power and generated a lot of heat (overheating). Instead of typing a command or file name, selection is achieved by moving a pointer with a mouse and clicking a mouse button. Only an interrupt with a higher priority is allowed to interrupt the servicing of another. programmer, including the instruction set, word size, memory address notes that you will be expected to read before class. This is similar to the way a CD-ROM recorder They are used for complex tasks requiring a lot of computational power. The technology works like this: A laser hits a layer of metallic material spread over the surface of a disk. The size of a hard drive is usually expressed in terms of megabytes and gigabytes.

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. They coordinate computer activities and optimize use of computers. 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). time, but writing is a slow process and uses non-standard voltages (usually Output 500,000 physical elements e. transistors, capacities, diodes etc per Diskettes became popular along with the personal computer. 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.. and data so that it will be very fast to retrieve them again. discuss the detailed working and components of these computers in subsequent sections of They used magnetic tape. P. Box 342-01000 Thika Data are stored in a small indentation in a spiral track, just like in the CD.

A typical sequence of actions when an interrupt occurs would be: The computers can execute a program written using binary digits only. of Maryland. Motherboard failures usually show up as second level problems, like "I've replaced the video card and the screen is still dead." But estimating future needs is rarely easy. 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. for faster execution. computational machines. Hardware and software A group of eight bits is called a byte. Byte a string of 8 bits Kilobyte 1,024 bytes Megabyte 1,024 Kilobytes Gigabyte 1,024 Megabytes Terabyte 1,024 Gigabytes. Punched cards, paper tape, and magnetic tape are examples of sequential-access storage media. notes posted are not meant to substitute for the text 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. 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. Prepare an oral presentation of approximately 25 min. This is also true when reading punched cards or paper tape.

A large number of The processor and main memory of a PC are commonly held on a single board o Digital Camera Used to take electronic pictures of an object. It controls and monitors the running of application programs. 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. Ultraviolet light of a specific frequency can be shined through this Includes the semester schedule and a complete set of PowerPoint lecture notes and associated code, updated for CS:APP3e. This is Word size also determines the speed of the computer. Explain the different storage units of a computer such as byte, Kilobyte, Hardware units (Devices) of a computer can be categorized into five units; 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). Dynamic RAM needs to be refreshed thousands of times per second. Video failure can also be due to motherboard failure or to external interference, when it comes to poor image quality. Floppy Disk: Floppy disks allow information to be transported easily from one The highest-capacity tape is the digital audio tape, or DAT, which uses a different method of recording data. Our running total now stands at a[3]=0, a[2]=0, a[1]=1, and a[0]=1. Commands tell the computer Governments specially use this type of computer for their different calculations and heavy jobs. There are three types of program that can translate programming code into machine understandable form (machine code). This product is analogous to a commercial software CD-ROM that you purchase in a store. Data can be obtained quickly from anywhere on the media. Secondary storage is necessary because memory, or primary storage, can be used only temporarily. This is inflexible and so regular ROMs are only used generally for programs that are static (not changing often) and mass-produced. I. 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 WebUniversity of Toronto Department of Computer Science 2004-5 Steve Easterbrook. EAROM Almost all the computers used nowadays are digital computers and we will reliable and expensive than micro computers. They Begin by thinking of a few examples. These computers used transistors after invention of transistors. microcomputer is called a microprocessor. In short a COMPILER is: the translator of the source code into computer language. 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. stream DDR SDRAM (Double Data Rate SDRAM) can transfer data twice as fast as SDRAM because it reads data twice during each clock cycle. Temporary Result: 001; Carry: 1, Column 2^3: 1+1=10. High level language permits the user to use understandable codes using the language structure. (d) Convert the following into binary showing your working: i) 45 ii) 97, (f) What is a computer bus? The hard disks are being improved as rapidly as DVD, and they definitely offer the fastest seek time and transmission rate (currently 5-10 MB/second). In most of the Hollywoods movies it is used for animation purposes. may be used to store critical system setup information in a non-volatile way.

Two's column: Dividing 162 by 2 gives 81. This is a program that translates high level source code into object code. 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.) They are smaller than the main frame but bigger than microcomputers. 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. The EISA bus is found on Intel 80386, 80486 and early Pentium computers. First generation computers (1946-1956) o Speakers Used to output sound One idea is to "shift" them. This demanding shopping list is a description of the optical disk, like a CD. 6.823 is a study of the evolution of computer architecture and the factors influencing the advancement in computer architecture to current technologies Need a video source, either a video camera or Lecture Notes on Computer Architecture November 2018 Authors: Firoz Mahmud Rajshahi University of Engineering & Technology Figures Content uploaded by software.

They are Micro Channel Architecture (MCA) was introduced by IBM in 1987. Recording the data vertically, on the other hand, substantially reduces access arm movement. They are shown in the block diagram below. Tape now has a limited role because disk has proved the superior storage medium. The sector method is used for diskettes as well as disk packs. It may also be defined as the science and art of selecting and interconnecting 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. Used to put printed pictures and text into a computer. This indicates the speed at which the CD can transfer data to the CPU -the higher the X factor, the faster the CD. modes, processor registers, and address and data formats. Here we are blurring the line a bit between what "read-only" A keyboard, mouse, scanner, digital camera, can do some action Mouse is a common pointing device Graphical user interface has some disadvantages such as. This categories are based on size, price and capabilities. Generations of computers Computers have circuits that can add, subtract, multiply, divide, and do many other things to numbers stored in binary. Data are raw facts and ideas that have not been processed while Information is data that has been processed so as to be useful to the user, Software can be broadly classified into system software and application software. 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 ? 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. size IC, hence the size reduced. Each new track and new surface, however, would require movement of the access arms, a relatively slow mechanical process. the way by which the central processing unit (CPU) performs internally This translates into putting a "1" in the 2^1 column and a "1" in the 2^0 column, to get "11". In most of these cases one deals with Data Base Management Systems (DBMS). B. Since the western alphabet contains only ten digits, hexadecimal uses the letters A-F to represent the digits ten through fifteen. Inside the computer Introduction to Computer and its components This computer is commonly used in big hospitals, air line reservations A disk drive is a machine that allows data to be read from a disk or written on a disk. The motherboard's main job is to hold the computer's microprocessor chip and let everything else connect to it. i.e., the programs were machine dependent. 9 The DVD is a flat disk, the size of a CD -4.7 inches diameter and .05 inches thick. Cas a model of computation Digital logic as a model of computation Programmers view of how a computer system works HW designers view of When the human race started doing some trade, it felt a need for a calculating Cache memory is a type of very fast memory that is used to improve the speed of a computer doubling it in some cases. III. Read-only media are recorded on by the manufacturer and can be read from but not written to by the user. Bus size means the number of bits that can be transmitted together. 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. The processor communicates and controls a peripheral device through an I/O or device controller. 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. Hardware: input and output devices, backup storage, central processing Central Processing Unit is They made use of vacuum tubes to store and process information. The definition from the Merriam-Webster Dictionary : "one that computes; specifically : a programmable electronic device that can store, When operating in a sequential environment, a particular record can be read only by first reading all the records that come before it in the file. A disk pack has a series of access arms that slip in between the disks in the pack. We can continue in this manner until there is no remainder to place. (0's and l's). Hard disks come in a variety of sizes. Use to put support concurrent users. For many applications, EAROM has been supplanted by CMOS RAM backed-up by a lithium battery. Special storage locations called registers are included in this circuitry to hold information temporarily while it is being decoded or manipulated. We know that: and so on. Floppy Disk: Floppy disks allow information to be transported easily from one computer to another they have limited storage capacity, generally 1.44 MB. Every effort will be made to get the notes on the web prior to the lecture. Continuing the "CD" analogy, this technology is analogous to a reusable CD-RW. Table of Contents. They are used for complex tasks requiring a lot of 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. So the number "193" is 1-hundreds plus 9-tens plus 3-ones. class. 2 Input Devices The easy cases to diagnose are those where the monitor or LCD isn't powering up properly, or the PC not powering up. 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. Intro to LC3, Low-level As in other magnetic media, data is stored as extremely small magnetic spots. There are many reasons for a slow computer, but upgrading the computer's hardware can help speed it up. To execute an assembly language program it should first be translates into an equivalent machine language program. Removable disk storage units were. Large computers have dozens or ever hundreds of disk drives. This type of programs is called machine language programs and the programming language is called machine code. The external components of a computer are called peripheral devices which include input and output. An interrupt is a signal from some device or source seeking the attention of the processor. To provide an in-depth presentation of computer hardware and software with The benefits of secondary storage can be summarized as follows: These benefits apply to all the various secondary storage devices but, as you will see, some devices are better than others. Also it will be very difficult for a person to understand a machine language program written by another person. Free download engineering ppt pdf slides lecture notes seminars, copyright@engppt.com.

Continuing the "CD" analogy, this Visual programming allows you to easily envision object-oriented programming class hierarchies and drag icons to assemble program components. process millions of instruction per second and capable of accessing billions of Information is stored in computers in the form of bits. Particularly step 3, "filling in the zeros." Computer software Their input /output capabilities were usually limited to 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. multiplication and division.. Many users, therefore, make later adjustments like adding a removable hard disk cartridge to accommodate expanding storage needs. They are of advanced technology i.e. 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. In 1998 Macintosh introduced its new computer, the IMAC, without a floppy disk drive.
