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. The cost of computers decreased and the speed increased. This process continues until we have a remainder of 0. them on the computer. The width of an address bus, along with the size of addressable memory elements, determines how much memory can be accessed. B. blueprint and functional description of requirements and design In these computers, all processing Intro to LC3, Low-level 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. A set of programs associated with the operation of a computer. This gives us the rightmost digit as a starting point. This document should be seasone Computer Architecture and Assembly Language Programming, Computer Organization and Design 4th Edition Solution, Comporg 6 sol2 - Solution manual for the second Chapter of the Computer Architecture, CS401 Quiz 1 Solution by MCS of Virtuallians. 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. You cannot read just any record at random. (a) Vacuum tubes (b) Capacitors (c) Transistors (d) Integrated circuits, The third generation of computers used 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. 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. Only an interrupt with a higher priority is allowed to interrupt the servicing of another. I. Software is simply set of instructions that cause a computer to perform one or more tasks. A group of eight bits is called a byte. more detail than the book and you are expected to read them and read Number Many cartridges and cassettes have the supply and take-up reels built into the same case. Hybrid Computers: Hybrid computers incorporate the technology of both analog and chip(IC). Central Processing Unit is implemented in a single piece of silicon device known as a computer chip. It is used more like a ()hard drive than as ()RAM. Our running total now stands at a[3]=0, a[2]=0, a[1]=1, and a[0]=1. Temporary Result: 01; Carry: 1, Column 2^2: 1+0=1 Add 1 from carry: 1+1=10. Computer architecture comprises at least three main subcategories: Instruction set architecture, or ISA, is the abstract image of a computing MGEG is the data coding for movies similar to JPEG for pictures.) chapters. This translates into putting a "1" in the 2^1 column and a "1" in the 2^0 column, to get "11". software. (a) Vacuum tubes (b) Capacitors (c) Transistors (d) Integrated circuits, Which one of the following types of computers is commonly used in offices The registers shown in the block diagram above, which represents a typical computer, each have a specific purpose, which is described below. Brooks, Planning a Computer System, Project Stretch, 1962 What does this design consist of? Logical operations it compares two data items to determine whether the They coordinate computer activities and optimize use of computers. and data so that it will be very fast to retrieve them again. Micro computers character recognition (OCR) software is needed A disk drive is a machine that allows data to be read from a disk or written on a disk. 17. Almost as intuitive is the number 5: it is obviously 4+1, which is the same as saying [(2*2) +1], or 2^2+1. You will see that it is the same procedure, but with sixteen digits instead of 10 or 2. The CPU of a the micro era based on large scale integration that confines several physical components per small elements thumb size IC, hence the size reduced. Once again, we are out of digits in the first column, so we add one to the next column. Windows is a Graphical user interface based operating system. storage To multiply by two, just add a 0 on the end. Chapter 1- Fundamentals of Computer Design. Each peripheral device operates in a different way and hence these devices cannot be connected directly to the processor. typing, recording keeping, production of financial statements, drawing, and statistics. Commands tell the computer to do something, like save the file. Thus, our number is 1001011. The two components (hardware, software) will be discussed later in other A hard disk is a metal platter coated with magnetic oxide that can be magnetized to represent data. refer to the Made of flexible Mylar, a diskette can record data as magnetized spots on tracks on its surface. Memory parity error, Arithmetic overflow Division by zero Attempt to execute an illegal machine instruction Reference outside a users allowed memory space, Generated by internal clock within the processor, I/O device signals normal completion or the occurrence of an error condition. Put 1 in the 2^1 column, 0 in 2^2, and subtract 2 from 3. But this is not practical for a system with many files or many users. Computers have continued to decrease in size but the processing power has links that I will post to other websites. The processor also stores the instructions being currently executed into the main memory. It The first place to start is always confirming that the power supply is operating properly. Because of their digital nature, a computer's electronics can easily manipulate numbers stored in binary by treating 1 as "on" and 0 as "off." A set of programs associated with the operation of a computer. The next change came after about 1600 years. consumed a lot of power and generated a lot of heat (overheating). erased and reprogrammed. Fourth GL Programming languages are closer to human languages than typical high-level programming languages.

Perhaps more important than capacity, however, is the convenience of speed. (e) Computers have evolved through many generations over the explain the five generations the computers have evolved through. 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. P.O. The following are the different types of interrupt that could occur; There is a special register in the CPU called the interrupt register. ROM package, through which you can actually see the chip that holds the information and issue commands to the computer. dynamic data structures in C, Instructions The take-up reel always stays with the magnetic tape unit. Cache memory is a type of very fast memory that is used to improve the speed of a computer doubling it in some cases.

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. This means that the tracks on the outside are not storing data as efficiently. The supply reel, which has the tape with data on it or on which data will be recorded, is the reel that is changed. Follow the same rules as in decimal division. can do some action Mouse is a common pointing device The processor and main memory of a PC are commonly held on a single board o Speakers Used to output sound 9 The DVD is a flat disk, the size of a CD -4.7 inches diameter and .05 inches thick. The disk in its drive is shown in Figure 3. i. They can be linked to smaller computers and handle hundreds of users they are also used in space exploitation. It is designed to perform a specific function and cannot be Box 342-01000 Thika info@mku.ac.ke Email: www.mku.ac.ke Web: Instructional Manual for BBIT Distance Learning. Hard disks use magnetism, while computer memory uses electric charges stored in tiny capacitors to indicate "on" or "off.". WebLecture notes Chapters 1-3, 5-12 The CMU ICS+ coursethat covers everything in CS:APP3e except Chapter 4 (Processor Architecture). When the processor wishes to read a word (say 8, 16, 32 bits) of data from memory, it first puts the address of the desired word of the address bus. The number 81 in binary would also have a 1 in the 2^0 column. C. Motherboard and CPU Troubleshooting ()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. ); it can be written to, but only once. They A rule of thumb among computer professionals is to estimate disk needs generously and then double that amount. temperature, speed etc. Used to put printed pictures and text into a computer. A graphical user interface (GUI) allows the user to interact with the system using Windows, Icons, Menus, and Pointers to control the operating system. modes, processor registers, and address and data formats. generation saw the introduction of more complex ALU and CPU, the use of high Converting from decimal to binary notation is slightly more difficult conceptually, but can easily be done once you know how through the use of algorithms. A CD-RW allows you to read, write, erase and write again. They support concurrent users. They are smaller than the main frame but bigger than microcomputers. This indicates the speed at which the CD can transfer data to the CPU -the higher the X factor, the faster the CD. III. 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. The truth is, of all the four subsystems represented in this table, hard drives are probably the most reliable. erasability is the EEPROM , which can be erased under software control. The pictures We know that: and so on. EAROM may be used to store critical system setup information in a non-volatile way. and that this is equivalent to (1*2^1)+(1*2^0). and cost goals. o Microphone Used to put sound into a computer. 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! DVD disks are read by a laser beam of shorter wave-length than used by the CD ROM drives. contains materials that are frequently examined. The most prominent optical technology is the CD-ROM, for compact disk read-only memory. Hardware 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. the capacity to hold significantly more data than a 5-1/4 inch diskette. 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. 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. Record the 1. 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. Annals of Business Administrative Science, 16(2), 91-102. Their input /output capabilities were usually limited to The purpose of the control bus is to transmit command , timing and specific status information between system components such as the memory, processor, keyboard input controller VDU output controller and the Disk I/O controller. When you start troubleshooting a dead computer, never ignore the possibility that the AC power to the PC's power supply is at fault. The size of a hard drive is usually expressed in terms of megabytes and No optic media can keep up with this.

The external components of a computer are called peripheral devices which include input and output. Computers, in contrast, permit storage on tape or disk in extremely compressed form. II. The highest-capacity tape is the digital audio tape, or DAT, which uses a different method of recording data. Software: Categories of software, System software, applications software, memory. Operating systems(OS) acts as an interface between the computer hardware and the computer user and manages the whole computer system. 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. During interpretation no object code is produced, and so the program has to be interpreted each time it is to be run. Students who are still learning the basics of computer repair, like what components are involved in what operation, will frequently assume that all boot issues are due to a hard drive failure. They can be linked to smaller Hexadecimal works in the same way as binary and decimal, but it uses sixteen digits instead of two or ten. Please note the direction of the arrows as it depicts the flow of the data and instructions. slower and less costly compared to mainframe computers but more powerful, WebComputer hardware components can generally be broken down into three categories: Processing Processing components are responsible for actually carrying out actions in Organization: Cache, Main Memory, When you play movies, your hardware (MPEG decoder. This document The speed of these machines was described in milliseconds (1/1000 of a second). They are more susceptible to physical damage and viruses than the hard drive. the required results faster than human beings. Temporary Result: 001; Carry: 1, Column 2^3: 1+1=10. 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. 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. Consists of programs that control operations of the computer and enable user to make efficient use of computers. A computer is an electronic device capable of executing instructions, developed This generation marked the origin of mini computers in use today. Magnetic tape looks like the tape used in music cassettes plastic tape with a magnetic coating. Data can also be destroyed if a read/write head encounters even minuscule foreign matter on the disk surface. taken by a digital camera can be used directly by a computer 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. When the CPU wishes to access a particular memory location, it sends this address to memory on the address bus. of Maryland. The first column we fill is the rightmost column, which is 2^0, or 1. Super computers are biggest in size, the most expensive in price than any other is smaller cheaper and produced less heat than vacuum tubes and consumed less These computers used transistors after invention of transistors. It is the smallest of the three computers. floppy disk controller. Most mainframe computers have 32-bit words. They were They are smaller than the main frame but bigger than microcomputers. In 1833, Prof. Charles Babbage, the father of the computer, developed a machine 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). A. retrieve, and process data", What different types of computers are there? product problem - assembly code, Introduction They used magnetic tape. In assembly language mnemonic codes are used to develop program for problem solving. multiple processor system with parallel processing. of computer is also helpful for forecasting weather reports worldwide. `P|U`J]Jsf/=*mhA*x+*v PuHMf yoPpile.K9^bEjed*csaE'ZaT1w@gTo7t Binary addition works on the same principle, but the numerals are different. 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. Data access A different ISR is provided for each different source of interrupt. Governments specially use this type of computer for their different This is the most flexible type of ROM, and is now commonly used for holding BIOS programs. 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. size though today the term is used to refer to large computers. However, you probably want to store the data you have used or the information you have derived from processing; that is why secondary storage is needed. Users plugged components like floppy drive controllers and ()memory into the slots. These are: An assembler is a program that translates assembly code into machine code. Topics may include: instruction set design; processor micro-architecture and Internal hardware of a computer. (Photo openphoto.net. Used with permission.) They are mainly used for presentations. << /Length 4 0 R /Filter /FlateDecode >> Information is stored in computers in the form of bits. We know that since it is odd, there must be a 1 in the 2^0 column (a[0]=1). Flash memory is a type of EEPROM chip, which stands for Electronically Erasable Programmable Read Only Memory. We also know that it equals 162+1. This holding place is known as memory also called main storage and is internal to the computer consisting of RAM and possibly ROM. The tubes consumed a lot of power and generated a lot of heat (overheating). EAROM Memory used includes magnetic disc and optical disc. 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). Lecture 21 (TBS): At the end of the chapter the learner shall be able to; However, this is not the only approach possible. -- you are required to read the textbook before (and after) each class. The size of a hard drive is usually expressed in terms of megabytes and gigabytes. design and fundamental operational structure of a computer system. 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. An interrupt is a signal from some device or source seeking the attention of the processor. Define computer data storage. You can also use software to edit the items you In some disk drives the access arms can be retracted; then the disk pack can be removed from the drive. level languages and provision of system software with the computer. The second The easy cases to diagnose are those where the monitor or LCD isn't powering up properly, or the PC not powering up. I. 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. III. A data bus provides a bi-directional path for moving data and instructions between system components. Electrically Erasable Programmable ROM (EEPROM): The next level of Optical storage technology is categorized according to its read/write capability. Other controllers operate in one direction only, either as an input controller, e.g. Computer software The micro chip technology has enabled reduction of size of. These computers used transistors after invention of transistors. They were huge in size and occupy a room. Diskettes became popular along with the personal computer. Hexadecimal is more compact than binary but is still based on the digital nature of computers. Software many applications, EAROM has been supplanted by CMOS RAM backed-up by technology is analogous to a reusable CD-RW. Fault Diagnosis I. 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. )wG-$b!vQs@K%quHPg$*^SQ2W9DmwC~#p2Yq$ 6QY >.Se:;r,Cfmw>?o"Nf=n=EV-$k_yBpR!lde])Y^o$,"*Tt *ieHqnUHHq 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. 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. 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. Icons represent programs, groups of programs, folders, devices and files. notes posted are not meant to substitute for the text Decode translate the program instruction into commands that the q .ZVPDo0)J+dlCIR^oQj"423IEuc &({-#s4JbfzXEF **HoZoO"*Ep_\C##Y$n1X qK%s[VJNh )$W~!P`0,v 2=i)|2#KmVdHofC contains materials that are frequently examined. This method produces high density and faster access to data. 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. Most 4GLs are used to access databases. next change came after about 1600 years. Now we need to do the remaining digits. Floppy Disk: Floppy disks allow information to be transported easily from one computer to another they have limited storage capacity, generally 1.44 MB. It may also be defined as the science and art of selecting and interconnecting To appreciate this, suppose you had an empty disk pack on which you wished to record data. general purpose software, integrated packages and software suites. NB: Nowadays most of the general purpose software is being sold as a complete software suites such as Microsoft office or Lotus SmartSuite. classified and known as super computer. Here, a given item of data can be selected from anywhere in storage without having to scan any preceding items. read from them many times. Since the western alphabet contains only ten digits, hexadecimal uses the letters A-F to represent the digits ten through fifteen. Power Supply Troubleshooting 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. o Voice input device- A computer I/O device in which vocal commands c l oc k , registers CHAPTER 2: BASIC HARDWARE UNITS OF A COMPUTER 14, CENTRAL PROCESSING UNIT (CPU)/PROCESSOR: 16, HOW INFORMATION IS STORED IN COMPUTERS 21, CHAPTER FIVE: INPUT AND OUTPUT DEVICES AND INTERRUPTS 39, THIRD GENERATION HIGH LEVEL LANGUAGES 43, CHAPTER EIGHT: DISKS AND SECONDARY STORAGE 55, CHAPTER NINE: HOW TO UPGRADE A SLOW COMPUTER 67, CHAPTER TEN: INTRODUCTION TO BINARY NUMBERS 70, BASIC CONCEPTS BEHIND THE BINARY SYSTEM 71, ANOTHER ALGORITHM FOR CONVERTING DECIMAL TO BINARY 77. o LCD Projectors Similar to monitors but projects an image on to a screen.
