It These are: An assembler is a program that translates assembly code into machine code. The registers shown in the block diagram above, which represents a typical computer, each have a specific purpose, which is described below. Try converting these numbers from binary to decimal: | | | 1 | 0 | | 1 | 1 | 1 1 | 0 | 1 | 0 | 1 1 | 1 | 1 | 1 | 0. In these computers, all processing It also makes the network transparent to the user, allowing any user with appropriate access rights to use software stored on the networks file server, and to store data either on the file server or on a local hard or floppy disk. You should also Eight's column: We can divide by two again to get 20. Tape now has a limited role because disk has proved the superior storage medium. 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. WebLecture notes Chapters 1-3, 5-12 The CMU ICS+ coursethat covers everything in CS:APP3e except Chapter 4 (Processor Architecture). The data is recorded on the tracks that can be accessed by one positioning of the access arms-that is, on one cylinder. Word size also determines the speed of the computer. This is sometimes referred to as direct overwriting and can be repeated several thousand times per disc. Number companies, and many other huge companies prefer mainframe because of its Different industries also use this huge computer for designing their products. 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! lecture notes available from the. requiring expensive equipment. Data files may be stored on or in sequential-access storage, direct-access storage, or random-access storage. There is more than one way of physically organizing data on a disk. You should also refer to the lecture notes available from the textbook website. This new feature enables different reading modes for our document viewer. 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. This is similar to the way a CD-ROM recorder works by letting you "burn" programs onto blanks once and then letting you read from them many times. A binary digit (1 or 0) is known as a BInary digiT which in short is a bit. They are more susceptible to physical damage and viruses than the hard drive. 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. for faster execution. The older diskette, 5-1/4 inches in diameter, is still in use, but newer computers use the 3-1/2 inch diskette (Figure 1). A set of programs associated with the operation of a computer. A set of programs associated with the operation of a computer. designing their products. erasability is the EEPROM , which can be erased under software control. Since we already knew how to convert from binary to decimal, we can easily verify our result. 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. The easy cases to diagnose are those where the monitor or LCD isn't powering up properly, or the PC not powering up. They are used for complex tasks requiring a lot of The disk in its drive is shown in Figure 3. The set of instructions is often called a program or, if the set is particularly large and complex, a system. WebComputer Architecture - Class notes. 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. with the ISA. The technology works like this: A laser hits a layer of metallic material spread over the surface of a disk. Cache memory Software: Categories of software, System software, applications software, Looking at this in columns. This categories are based on size, price and capabilities. The pictures Announcements Contact Information Lecture Notes: Lectures marked TBU will be updated as semester progresses. Next, we focus specifically on the CPU (Central Processing Unit). Erasable Programmable ROM (EPROM): An EPROM is a ROM that can be erased and reprogrammed. The chipset is part of the motherboard's logic system and is usually made of two parts --the northbridge and the southbridge. These computers are used in networking .examples of micro computers are IBM PCs BBC micro etc. << /Length 4 0 R /Filter /FlateDecode >> Chapter 1- Fundamentals of Computer Design. {HnzIxfjw^K](^$L Although the user enter data in decimal or character form, it is converted into binary digits 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). size IC, hence the size reduced. This is inflexible and so regular ROMs are only used generally for programs that are static (not changing often) and mass-produced. 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. We begin with a look at the various storage media, including those used for personal computers, and then consider what it takes to get data organized and processed. them on the computer. drive. where each a[i] is either a 1 or a 0 (the only possible digits for the binary system). computer. Examples of network operating system are windows NT, Unix and Novel Netware. works by letting you "burn" programs onto blanks once and then letting you 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. (b) List four of the conditions an ALU tests for. They Record the 11. Binary is an effective number system for computers because it is easy to implement with digital electronics. It may also be defined as the science and art of selecting and interconnecting Programming: I/O, Traps and Web: mku.ac. 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. Rewriting an EAROM is intended to be an infrequent operation -most of the time the memory is used as a ROM. II. Then, replace each block of four digits with its corresponding hexadecimal digit. There are several specific form factors that most PC motherboards use so that they can all fit in standard cases. video recorder It Converts an The EISA bus is found on Intel 80386, 80486 and early Pentium computers. Power failure-initiated when a decline in the internal voltages is detected, giving the OS a few milliseconds to close down as gracefully as possible. ii. Cache memory is a type of very fast memory that is used to improve the speed of a computer doubling it in some cases. the lecture -- the notes posted here provide, in some cases, more It acts as an intermediate store between the CPU and the maim memory, and works by storing the most frequently or recently used instructions and data so that it will be very fast to retrieve them again. 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. WebCS385 Computer Architecture, Lecture 1 Reading: Patterson & Hennessy - Chapter 1 Topics: Introduction, Computer Architecture = Instruction Set Architecture + Machine Tapes come in a number of forms, including l/2-inch-wide tape wound on a reel, l/4-inch-wide tape in data cartridges and cassettes, and tapes that look like ordinary music cassettes but are designed to store data instead of music. Hard Drive: class. 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. The term mainframe was mainly used for earliest computers as they were big in microcomputer is called a microprocessor. 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 ? o Speakers Used to output sound So the number "193" is 1-hundreds plus 9-tens plus 3-ones. Compact Disk Read Only Memory (CD ROM): CD ROMs are read only storage medium.

This product is device. The DVD drives come in 2X, 4X, etc. 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. level languages and provision of system software with the computer. giving the computer commands called command or function keys The micro chip technology has enabled reduction of size of. Organization: Cache, Main Memory, 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. 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. Optimization, Memory This type of programs is called machine language programs and the programming language is called machine code. WebLecture #4-5: Computer Hardware (Overview and CPUs) CS106E Spring 2018, Young In these lectures, we begin our three-lecture exploration of Computer Hardware. For implementations for the various parts of a computer, focusing largely on 6.823 is a study of the evolution of computer architecture and the factors influencing the The number 76, for example, takes only two digits to write in decimal, yet takes seven digits to write in binary (1001100). As we have already noted, magnetic tape is used primarily for backup purposes. The CPU and the RAM are two main components that can be upgraded to increase a computer's speed, though doing this may require replacing the motherboard as well. Intel Core i3, i5 and i7 are 1.2 GHz to 3.33 GHz, 1.06 GHz to 3.6 GHz and 1.06 GHz to 3.46 GHz, respectively. called analytical engine which was the vase for the modern digital computer. They can be linked to smaller In our vertical notation. The arithmetic/logic unit(ALU) plays two roles. Continuing the "CD" analogy, this Compiler, Program 17. PROM, but it does require the erasing light. In fact, programming a PROM is also called burning, just like burning a CD-R, and it is comparable in terms of its flexibility. Most 4GLs are used to access databases. Introduced the use of very small electronic circuit called integrated circuits (IC) by combining several transistors together between 3 transistors to make 1 IC. Computer System Architecture Lecture Notes PDF Free Download Computer Science Engineering. interoperate in order to implement the ISA. Memory allocation: malloc and Almost all the computers used nowadays are digital computers and we will may be entered into a computer system. No optic media can keep up with this. The methods we will consider here are the sector method and the cylinder method. erased and reprogrammed. The outer gold layer is semi transparent, to allow reading of the underlying silver layer. Magnetic tape looks like the tape used in music cassettes plastic tape with a magnetic coating. These computers were mostly At the beginning of each fetch-execute cycle, the interrupt register is checked. This is mostly hard drives and removable media such as floppy disks, optical media (CD ROM) etc. 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). A 4GL is an aid which the end user or programmer can use to build an application without using a third generation programming language. 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. gigabytes. Many disk devices, however, do not record data on the top of the top platter or on the bottom of the bottom platter. You can also use software to edit the items you Define computer data storage.

Kurose,W. The following program written in BASIC language is to add two given numbers. The code written by the programmer is called the source code and the compiled code is called the object code. A hard disk is a metal platter coated with magnetic oxide that can be magnetized to represent data. A motherboard by itself is useless, but a computer has to have one to operate. time was measured in micro-seconds. must begin on a clock pulse, although some activities take more than one clock pulse to complete. Unlike competing standards, SCSI is capable of supporting eight devices, or sixteen devices with Wide SCSI. Dividing 80 by 2 gives 40. can do some action Mouse is a common pointing device This is useful for companies that make their own ROMs from software they write, because when they change their code they can create new PROMs without requiring expensive equipment. 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. This product is analogous to a commercial software CD-ROM that you purchase in a store. The highest-capacity tape is the digital audio tape, or DAT, which uses a different method of recording data. This is significant data insurance. EAROM )fb1{`BF 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. We start by looking at the different types of computer components and how they interact during basic computer operations. The size of a computer's cache Explain the different hardware units of a computer system such as input, They are smaller than the main frame but bigger than microcomputers. Personal computer users, who never seem to have enough hard disk storage space, may turn to a removable hard disk cartridge. In binary, any digit higher than 1 puts us a column to the left (as would 10 in decimal notation). The EISA bus provided 32-bit slots at an 8.33 MHz cycle rate for the use with 386DX or higher processors.

It is inefficient for humans to use binary, however, because it requires so many digits to represent a number. As you know, the decimal system uses the digits 0-9 to represent numbers. higher voltages around 12 volts). Each byte can be used to represent a number, letter or special character. I. When we talk about troubleshooting video failures, we're usually talking about no image at all on the screen. Thus, we would put a 1 in the 2^6 column, and subtract 64 from 75, giving us 11. contains materials that are frequently examined. They have higher main memory capacity, reliable and increased processing power (have the capability of holding more than one set of instructions and operate on them) than the second generation computers. In 1833, Prof. Charles Babbage, the father of the computer, developed a machine Diskettes became popular along with the personal computer. At the end of the chapter the learner shall be able to; more detail than the book and you are expected to read them and read II. system that is seen by a machine language (or assembly language) The processor contains the control unit and the arithmetic/logic unit(ALU) and the system clock. video into a computer. Chapter 3- Instruction They are The speed of these machines was described in microseconds (1/1000, 000 of a second). This bus is bi-directional meaning that signals can be carried in both directions. We know that since it is odd, there must be a 1 in the 2^0 column (a[0]=1). Since Assembly language is machine dependent each type of computer has its own assembler. (0's and l's). Floppy Disk: Floppy disks allow information to be transported easily from one The control unit operates by repeating three operations which are: Fetch cause the next instruction to be fetched from memory; Computer systems are constructed of digital electronics. Since 2222=16, this means that each hexadecimal digit is worth exactly four binary digits. C. Characteristics of computers It can process trillions of instructions in seconds. In some disk drives the access arms can be retracted; then the disk pack can be removed from the drive. The speed of these machines was described in milliseconds (1/1000 of a second), Second generation computers (1957-1967) window for a specified period of time, which will erase the EPROM and allow it But the DVD will undoubtedly gain a place as the successor to the CD ROM and is playing an important role in the blending of computers and entertainment centers. computer can process computational power. Some systems feature dual BIOS, which provides a backup in case one fails or in case of error during updating. B. Electrically Alterable Read-Only Memory(EAROMs) can be modified a bit at a The following are the different types of interrupt that could occur; There is a special register in the CPU called the interrupt register. Disk data is quite reliable, especially within a sealed module. A disk pack is mounted on a disk drive that is a separate unit connected to the computer. Also these programs written for execution in one computer cannot be used on another type of computer. You are required to Begin by thinking of a few examples. individuals. Over 100's of millions have been sold, making it the de facto standard. size though today the term is used to refer to large computers. Super computers are biggest in size, the most expensive in price than any other is classified and known as super computer. Hardware: input and output devices, backup storage, central processing Data thus saved can be restored to the hard disk later if needed. Computer System Architecture Notes: Computer C. The motherboard; form factor, sockets and slots Each disk in the pack has top and bottom surfaces on which to record data. These computers had programming languages whose vocabularies are close to the human natural language, English language. At present, computer users do not write programs using machine language. typing, recording keeping, production of financial statements, drawing, and statistics. The small circuitry that resulted improved the processing speed i.e. According to the utilization of computer for different uses, computers are of following two types: According to the technology used, computers are of following three types: Computer hardware refers to the physical components of a computer such as the monitor, Keyboard, Mouse, system unit etc. links that I will post to other websites. The speed of these machines was described in milliseconds (1/1000 of a second). 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. and accesses addresses in memory. a lithium battery. increased. A rule of thumb among computer professionals is to estimate disk needs generously and then double that amount. Hardware and software The first column we fill is the rightmost column, which is 2^0, or 1. Windows is a Graphical user interface based operating system. B. 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) Supercomputers (b) Mainframe (c) Mini computer (d) Micro computer. As in other magnetic media, data is stored as extremely small magnetic spots. (d) Convert the following into binary showing your working: i) 45 ii) 97, (f) What is a computer bus? the keyboard and or punched card input and printer and or punched cart output. That means that their electronic circuits can exist in only one of two states: on or off. Email: info@mku.ac This fact makes it easy to convert between binary and hexadecimal. NB: Nowadays most of the general purpose software is being sold as a complete software suites such as Microsoft office or Lotus SmartSuite. Each new track and new surface, however, would require movement of the access arms, a relatively slow mechanical process. memory. The control unit coordinates and controls all the operations carried out by the The processor can read and write into the secondary storage devices. These patterns of "on" and "off" stored inside the computer are used to encode numbers using the binary number system. infrequent operation - most of the time the memory is used as a ROM. A typical data bus consists of 8, 16, or separate lines. Furthermore, graphics images and audio and video files require large file capacities. WebComputer architecture is the science and art of selecting and interconnecting hardware components to create a computer that meets functional, performance and cost goals. Box 342-01000 Thika info@mku.ac.ke Email: www.mku.ac.ke Web: Instructional Manual for BBIT Distance Learning. programs. 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. Input devices enter information to be processed by the processor. The record storage rooms would have to be enormous. Fuller F., Larson B., Computers: Understanding Technology(Second Edition) to be reprogrammed again. This is similar to the way a CD-ROM recorder 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. 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). The CPU is connected to the main memory by three separate buses. refer to the With any method of data storage, a backup system a way of storing data in more than one place to protect it from damage and errors is vital. Hardware A little glass window is installed in the top of the We can easily see that the number 3= 2+1. Consists of programs that control operations of the computer and enable user to make efficient use of computers. EISA is the second most commonly used interface for disk drives. Assembly language is designed mainly to replace each machine code with and understandable mnemonic code. (2mks) (b). The processor and main memory of a PC are commonly held on a single board called a mother board. There are different types of disk packs, with the number of platters varying by model. An operating system acts as foundation on which other application software can be installed. temperature, speed etc. the manufacturer. devices. Everything that runs the computer or enhances its performance is either part of the motherboard or plugs into it via a slot or port. Take a look at the images below on the right, as you can see, we have pointed out certain parts of the DIMM memory module and the DIMM slot. Also it will be very difficult for a person to understand a machine language program written by another person. 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). vdu controller.

In fact, flash memory is known as a solid state storage device, meaning there are no moving parts --everything is electronic instead of mechanical. monitor, Keyboard, Mouse, system unit etc. Many cheaper PC's ship with power supplies I would basically describe as "disposable." 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. Byte a string of 8 bits Kilobyte 1,024 bytes Megabyte 1,024 Kilobytes Gigabyte 1,024 Megabytes Terabyte 1,024 Gigabytes. To convert from hexadecimal to binary, simply look at the chart above and replace each digit in the hexadecimal number with its corresponding four-digit binary number. It has special keys for notes posted are a superset of what I will go over during Assembly language is translated into machine code using an assembler before they can be executed. In short a COMPILER is: the translator of the source code into computer language. Typically the clock pulse rate in 2000 is around 500 megahertz (million cycles per second). A keyboard, mouse, scanner, digital camera, touch pads and joystick are examples of input devices. When the CPU wishes to access a particular memory location, it sends this address to memory on the address bus. and cost goals. 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.
