P. Box 342-01000 Thika I. Erasable Programmable ROM (EPROM): An EPROM is a ROM that can be erased and reprogrammed. Once again, we are out of digits in the first column, so we add one to the next column. These computers were mostly computational machines. D. Hard Drive Failure Troubleshooting, V. Input and output devices and interrupts. We know that: and so on. WebLecture 1 : Evolution of Computer Systems: Download Verified; 2: Lecture 2 : Basic Operation of a Computer: Download Verified; 3: Lecture 3 : Memory Addressing and When you play movies, your hardware (MPEG decoder. 2022, Assignment 1. 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). In some disk drives the access arms can be retracted; then the disk pack can be removed from the drive. Research shows that the trend in computer technology revolution is that there is; A computer is an electronic device capable of executing instructions, developed based on algorithms stored in its memory, to process data fed to it and produce the required results faster than human beings. Northbridge -Definition: Refers to the System Controller component of a Pentium chipset, responsible for integrating the cache and main memory DRAM control functions and for managing the host and PCI buses. 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. (2017). Begin by thinking of a few examples. came UNIVAC (universal automatic computers). A disk pack has a series of access arms that slip in between the disks in the pack. To provide an in-depth presentation of computer hardware and software with We saved magnetic tape storage for last because it has taken a subordinate role in storage technology. The program given below shows assembly language program to add two numbers A & B. Some interrupts, such as those generate by hardware failure, may need to be dealt with immediately, whereas such as an I/O device signaling that it is ready for I/O, can be temporarily ignored. In effect, a removable cartridge is as portable as a diskette, but the disk cartridge holds much more data. modes, processor registers, and address and data formats. The OS controls who logs on to the network by means of user names and passwords, in order to protect the data and programs stored on the network. Email: info@mku.ac character recognition (OCR) software is needed The decimal number "2" is written in binary notation as "10" (1*2^1)+(0*2^0). o Speakers Used to output sound Web: mku.ac. computer can process window for a specified period of time, which will erase the EPROM and allow it While information retrieval is faster than from a floppy disk, it is still not as fast as from the hard drive. They are referred to as binary digits i.e. programs that are static (not changing often) and mass-produced. Storage capacity was 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. At the end of the chapter the learner shall be able to; They can be linked to smaller The easy cases to diagnose are those where the monitor or LCD isn't powering up properly, or the PC not powering up. They come highly recommended. This kind There is more than one way of physically organizing data on a disk. This is sometimes referred to as direct overwriting and can be repeated several thousand times per disc. Practically, we can simply keep a "running total", which now stands at 11 (a[1]=1 and a[0]=1). The commands are entered on a prompt for example the Ms Dos prompt looks like this. Computer hardware refers to the physical components of a computer such as the Bus size means the number of bits that can be transmitted together. 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. In decimal form, 1+1=2. Organization: Cache, Main Memory, o LCD Projectors Similar to monitors but projects an image on to a screen. 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. memory. To convert the decimal number 75 to binary, we would find the largest power of 2 less than 75, which is 64. A keyboard, mouse, scanner, digital camera, In order to execute a high-level language program, it should be translated into a machine language either using a compiler or interpreter. Since 00110101 has eight digits, it can be divided into two blocks of four digits, 0011 and 0101. State three types of computer buses. 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). P&H: Computer Organization & Design, by Patterson and Hennessy. The programs written in assembly language are also machine dependent. The speed of these machines was described in milliseconds (1/1000 of a second), Second generation computers (1957-1967) Over the years, newer computers have been introduced that contain faster microprocessors. The notches we have marked as B, are used to align the memory module with the DIMM slot keys C, as shown in Fig 1.3. Flash memory is a type of EEPROM chip, which stands for Electronically Erasable Programmable Read Only Memory. Take the number 163. The system unit is the unit that houses the processing unit (processor), memory, the input output controllers and the buses. %PDF-1.3 Although the EISA bus is backwards compatible and not a proprietary bus it never became widely used and is no longer found in computers today. unit, memory (ROM, RAM). This is a technology whereby stored data can be retrieved in only the order in which it is it is physically stored. 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. Four's column: Now we can subtract 1 from 81 to see what remainder we still must place (80). the 0s and 1s with 0 representing an OFF state and 1 representing an ON state. Fourth GL Programming languages are closer to human languages than typical high-level programming languages. The number 76, for example, takes only two digits to write in decimal, yet takes seven digits to write in binary (1001100). WebThis presentation is available free for non-commercial use with attribution under a creative commons license. 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. A way to organize data on a disk pack is the cylinder method. The second A command based interface is quick to operate and very flexible, but the user needs to learn all the commands and type them in correctly. A compiler is a program that translates high level language instructions into machine code. Icons represent programs, groups of programs, folders, devices and files. for instance, is an organizational issue that generally has nothing to do For the sake of simplicity, throw away the remainder. dj z(l6uHyB"C]Iie7tHDXWq@vd4KfqS)YZT&;"v%LqNm!ZTJ UWBD@^-1QA+'6b"V0s>x$*Y l(7`yAP. computer to another they have limited storage capacity, generally 1 MB. links that I will post to other websites. Two reels are used, a supply reel and a take-up reel. humans. Consists of programs that control operations of the computer and enable user to make efficient use of computers. The lecture notes posted are not Next, we focus specifically on the CPU (Central Processing Unit). A monitor, printer, and speakers are examples of output devices. Software is simply set of instructions that cause a computer to perform one or more tasks. 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! SDRAM (Synchronous DRAM) divides RAM into two separate memory banks to increase the processing of the memory requests. The explosive growth in storage needs has driven the computer industry to provide cheaper, more compact, and more versatile storage devices with greater capacity. Special storage locations called registers are included in this circuitry to hold information temporarily while it is being decoded or manipulated. Everything that runs the computer or enhances its performance is either part of the motherboard or plugs into it via a slot or port. The stored bits are usually retrieved from computers memory for manipulation by the processor. Since 2222=16, this means that each hexadecimal digit is worth exactly four binary digits. Here, a given item of data can be selected from anywhere in storage without having to scan any preceding items. They are expensive to install. Removable disk storage units were developed for use on these machines. 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. The input and output devices are discussed in details in chapter 2 of the module. We can continue in this manner until there is no remainder to place. 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). They are mainly used for presentations. for faster execution. This is also true when reading punched cards or paper tape. At the end of the chapter the learner shall be able to; A CD-RW allows you to read, write, erase and write again. drive. They are very large in size and use multiple processors and superior technology. It is designed to perform a specific function and cannot be changed. History of computers 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). Once the access arms are in position, they are in the same vertical position on all disk surfaces. Once the data has been processed by the processor, the data can be displayed by the output devices. discuss the detailed working and components of these computers in subsequent sections of 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: information and issue commands to the computer. 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." This generation marked the origin of mini computers in use today. 2. AxgyL@0#jE:3tBP20zivoKJ]2w\$wkNIkyDXQwsACvc; hq W j Over 100's of millions have been sold, making it the de facto standard. A bit is used to represent information in the computer. Programmable ROM (PROM): This is a type of ROM that can be programmed using special equipment (a PROM programmer. Although a hard disk is an extremely reliable device, a hard disk drive is subject to electromechanical failures that cause loss of data. Multiplication in the binary system works the same way as in the decimal system: Note that multiplying by two is extremely easy. Today, motherboards typically boast a wide variety of built-in features, and they directly affect a computer's capabilities and potential for upgrades. The real time clock chip is a battery-operated chip that maintains basic settings and the system time. If we put the 1 in the 2^0 column, we have 162 left, and have to decide how to translate the remaining digits. taken by a digital camera can be used directly by a computer Computer System Architecture Lecture Notes PDF Free Download Computer Science Engineering. (c) Explain the use of registers in the CPU. 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. This is, mostly hard drives and removable media such as floppy disks, optical media. advancement in computer architecture to current technologies Since these programs use only '0's and '1's it will be very difficult for developing programs for complex problem solving.

B. 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. 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. 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. Temporary Result: 001; Carry: 1, Column 2^3: 1+1=10. To appreciate this, suppose you had an empty disk pack on which you wished to record data. 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. product problem - assembly code, Introduction When you hear reference to a "flash BIOS" or doing a BIOS upgrade 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. You should also MGEG is the data coding for movies similar to JPEG for pictures.) Zip disks are a great way to store large files and software programs. Looking at this in columns. Then we just put this into columns. This is similar to the way a CD-ROM recorder 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. Picture Window theme. This allows for smaller indentations and increased storage capacity. (b) List four of the conditions an ALU tests for. 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. In the sector method each track is divided into sectors that hold a specific number of characters. o Number of components in computer per circuit (IC) greatly increased over Word size also determines the speed of the computer. 1 Lecture 21: Software Architectures 21-architecture.ppt Author: Steve Easterbrook Created Date: class. Web6.823 is a course in the department's "Computer Systems and Architecture" concentration. For example, to convert 110101 to hexadecimal, first add two zeros at the beginning of the number to make it 00110101. xH2Z@Qh>$p+![r5V28U<>hc`Ko3e7F^(CRz.]kA/()U&JxQ*r"?Da:)oW6LW8it^0!m OzDH Some modern Intel Core i3, i5 and i7 processor brands are split into desktop and laptop (or mobile) processors. The EISA bus is found on Intel 80386, 80486 and early Pentium computers. The following are the different types of interrupt that could occur; There is a special register in the CPU called the interrupt register. The term mainframe was mainly used for earliest computers as they were big in Chapter 3- Instruction 6.823 is a study of the evolution of computer architecture and the factors influencing the It is the main part of a computer system like the brain of a human being. Flash memory is used for easy and fast information storage in computers, digital cameras and home video game consoles. Output devices 5GL or fifth-generation language is programming that uses a visual or graphical development interface to create source language that is usually compiled with a 3GL or 4GL language compiler. the lecture -- the notes posted here provide, in some cases, more within a computing system such as: Objectives II. 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. (2mks) (b). Information is stored in computers in the form of bits. WebCS 135: Computer Architecture I Fall 2010 Lecture Notes. Also these programs written for execution in one computer cannot be used on another type of computer. Older Zip disks hold 100MB, newer ones hold 250MB and cost $8-$10 a piece (Floppies hold 1.4MB and cost around $2). Most disk packs, however, combine the disks, access arms, and read/write heads in a sealed module called a Winchester disk. We also know that it equals 162+1. 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. lecture notes available from the. This product is analogous to a commercial software CD-ROM that you purchase in a store. Computer architecture or digital computer organization is the conceptual ROM: A mask programmed read only memory that can be only be produced by Introduced the use of very small electronic circuit called integrated circuits (IC) by combining several transistors together between 3 transistors to make 1 IC.

Diskettes and hard disks are magnetic media; that is, they are based on a technology of representing data as magnetized spots on the disk with a magnetized spot representing a 1 bit and the absence of such a spot representing a 0 bit. microcomputer is called a microprocessor. o Video Capture Card Usually place inside the computer's case. Now I can imagine even the extra disk filling up.". This computer is commonly used in big hospitals, air line reservations Writing and understanding programs in assembly language is easier than that of machine language. 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. For many applications, EAROM has been supplanted by CMOS RAM backed-up by a lithium battery. All the processor activities, such as fetching an instruction, reading data into the memory register etc. called a mother board. o Scanner allows you to scan documents, pictures, or graphics and view chip(IC). This means that the tracks on the outside are not storing data as efficiently. In such a system a task is broken down and shared among processes for faster execution. i.e., the programs were machine dependent. In 1833, Prof. Charles Babbage, the father of the computer, developed a machine called analytical engine which was the vase for the modern digital computer. A keyboard, mouse, scanner, digital camera, touch pads and joystick are examples of input devices. Ch19 - Chapter 19 solution for Intermediate Accounting by Donald E. Kieso, Jerry J. Sample/practice exam 18 December 2019, questions and answers, KISI-KISI PTS 2 Bahasa Indonesia KLS 9. 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. Optimization, Memory A 4.7 GB side of a DVD can hold 135 minutes top quality video with 6 track stereo. 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. Each bit of the register represents a different type of interrupt, and if a bit is set, the state of the current process is saved and the operating system routes control to the appropriate interrupt handler. Such a disk cannot, obviously, be used for your files, but manufacturers can use it to supply software. In fact, programming a PROM is also called burning , 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. Interrupts are therefore assigned priorities so that when two interrupts are received simultaneously, the one with the highest priority is dealt with first. computational machines. Hard disk for mainframes and minicomputers may be as large as 14 inches in diameter. ); it can be written to, but only Compiler, Program Power supplies often fail gradually, giving rise to symptoms that appear to be caused by individual component failure. Typically the clock pulse rate in 2000 is around 500 megahertz (million cycles per second). Includes the semester schedule and a complete set of PowerPoint lecture notes and associated code, updated for CS:APP3e. Once full, a removable hard disk cartridge can be replaced with a fresh one. This computer is not used as a PC in a home neither by a student in a B. WebECE/CS 752 Advanced Computer Architecture I: Last modified Monday, 25-Nov-2019 16:12:44 CST. We learned earlier that there is a 1 in the 2^0 column if the number is odd. Computer systems are constructed of digital electronics. Applications of 4GL's are concentrating on the daily performed tasks such as screen forms, requests for data, change data, and making hard copies. Power Supply Troubleshooting The technology works like this: A laser hits a layer of metallic material spread over the surface of a disk. This places the data in diagonal bands that run across the tape rather than down its length. Record the 11. These computers had programming languages whose vocabularies are close to the human natural language, English language. Writing takes place in a single pass of the focused laser beam. 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. Most mainframe computers have 32-bit words. The amount of data on a tape is expressed in terms of density, which is the number of characters per inch (cpi) or bytes per inch (bpi) that can be stored on the tape. D&T: 18-213 18-240. 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." read the textbook and, preferably, the posted notes before coming to A large number of peripherals can be attached to them. design and fundamental operational structure of a computer system. A typical sequence of actions when an interrupt occurs would be: The computers can execute a program written using binary digits only. BUSES.. INTERRUPTS. ANOTHER ALGORITHM FOR CONVERTING DECIMAL TO BINARY, System interconnects such as computer buses and switches, CPU off-load mechanisms such as direct memory access (DMA), The second generation of computers used Compact Disk-Writable (CD-R): A CD-R is highly effective for storing a large amount of data. 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). 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. may be entered into a computer system. Record the 1. more emphasis on the more technical aspects of computing such as Final result: 11001. very low i. Computer software and data so that it will be very fast to retrieve them again. Once the commands are entered on the prompt a command line interpreter(CLI) identifies and executes the commands. smaller cheaper and produced less heat than vacuum tubes and consumed less Temporary Result: 11 New D=40 D does not equal 0, so we repeat step 2. Region one is USA and Canada, while Europe and Asia is region two. The speed of these machines was described in nanoseconds (1/1,000,000,000 of a second). It is a the maim memory, and works by storing the most frequently or recently used instructions Some systems feature dual BIOS, which provides a backup in case one fails or in case of error during updating. There are several specific form factors that most PC motherboards use so that they can all fit in standard cases. Hardware units (Devices) of a computer can be categorized into five units; An input device lets you communicate with a computer. 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. EAROM may be used to store critical system setup information in a non-volatile way. Furthermore, as we will see, disk data can be accessed directly, as opposed to data on tape, which can be accessed only by passing by all the data ahead of it on the tape. computational power. time was measured in micro-seconds. A motherboard allows all the parts of your computer to receive power and communicate with one another. Winchester disk assemblies are put together in clean rooms so even microscopic dust particles do not get on the disk surface. It controls and monitors the running of application programs. Our "new" 2^0 column now contains a1. level languages and provision of system software with the computer. Programmable ROM (PROM): This is a type of ROM that can be programmed 1 Software and Hardware 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. Programming and problem MCA, or the Micro Channel bus, was a competition for ISA bus. A typical data bus consists of 8, 16, or separate lines. classified and known as super computer. WebLecture notes Chapters 1-3, 5-12 The CMU ICS+ coursethat covers everything in CS:APP3e except Chapter 4 (Processor Architecture). Microcomputers can be a desktop, laptop, notebooks, or even palmtop.

Personal computer users find accessing files on a hard disk is significantly faster and thus more convenient than accessing files on a diskette. 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. 2kb and speed of processing was also very low. 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. Perhaps more important than capacity, however, is the convenience of speed. Execute cause the instruction to be executed. image into dots that the computer can understand .To scan text, optical Explain how the different units of a computer interact witch each other to The record storage rooms would have to be enormous. interoperate in order to implement the ISA. implemented in a single piece of silicon device known as a computer chip. It is the smallest of the three computers. support concurrent users. video into a computer. 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. 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. They are more susceptible to physical damage and viruses than the hard 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.
