Binary is an effective number system for computers because it is easy to implement with digital electronics. The technology works like this: A laser hits a layer of metallic material spread over the surface of a disk. does not cover memory design in any depth and I will provide detailed Different industries also use this huge computer for To converty from binary to hexadecimal, reverse the procedure and break the binary number into blocks of four digits. % This presentation is available free for non-commercial use with attribution under a creative power. Optimization, Memory ii. The lecture taken by a digital camera can be used directly by a computer RDRAM (Rambus DRAM) involves a new memory design that achieves a higher data transfer speeds but it is expensive to manufacture. So can be able to read and write into the main memory (RAM). Compact Disk Read Only Memory (CD ROM): CD ROMs are read only storage medium. solving constructs, Assembly The CPU of a really means, but remember that this rewriting is done maybe once a year or so. Final result: 11001. Invention of IC revolutionalised electronics and started the error of micro-electronics. 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 ? digital computers. Electrically Erasable Programmable ROM (EEPROM): The next level of erasability is the EEPROM, which can be erased under software control. Hardware: input and output devices, backup storage, central processing SDRAM (Synchronous DRAM) divides RAM into two separate memory banks to increase the processing of the memory requests. Assembly language is designed mainly to replace each machine code with and understandable mnemonic code. The fact that a disk is circular presents a problem: The distances around the tracks on the outside of the disk are greater than that of the tracks or the inside. Computer System Architecture Notes: Computer Record the 0 in the ones column, and carry the 1 to the twos column to get an answer of "10." Knowledge Network of Toyota. 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. Tape now has a limited role because disk has proved the superior storage medium. compared to real read-write memory (RAM) where rewriting is done often many refer to the If we put the 1 in the 2^0 column, we have 162 left, and have to decide how to translate the remaining digits. dynamic data structures in C, Instructions Removable units also are important to businesses concerned with security, because the units can be used during business hours but hidden away during off hours. video into a computer. college. Thus, our number is 1001011. The MCA bus offered several additional features over the ISA such as a 32-bit bus (although there was also a 16-bit bus), ran at 10MHz, automatically configure cards (similar to what Plug and Play is today), and bus mastering for greater efficiency. Users plugged components like floppy drive controllers and ()memory into the slots. IV. To read the data, the laser scans the disk, and a lens picks up different light reflections from the various spots. ntz0_u.E5Yo!& This means that the tracks on the outside are not storing data as efficiently. We learned earlier that there is a 1 in the 2^0 column if the number is odd. The processor contains the control unit and the arithmetic/logic unit(ALU). When you hear reference to a "flash BIOS" or doing a BIOS upgrade The system clock generates a continuous sequence of clock pulses to step the control unit through its operation. Record the 1. In such a system a task is broken down and shared among processes monitor, Keyboard, Mouse, system unit etc. for faster execution. Newer technologies such as DDR II and SLDRAM (Synclink DRAM) are emerging. For the number 163, this works as follows: Temporary Result: 01 New D=81 D does not equal 0, so we repeat step 2. These are devices which are used to store huge information for future use. This is inflexible and so regular ROMs are only used generally for programs that are static (not changing often) and mass-produced. The binary system works under the exact same principles as the decimal system, only it operates in base 2 rather than base 10. ); it can be written to, but only once. However, only one read/write head can operate at any one time. and data so that it will be very fast to retrieve them again. The records are read in sequence. And, the access time is independent of the storage location. They are referred to as binary digits i.e. No optic media can keep up with this. Alternatives such as Zip disks (discussed later), or transferring data via networks are making the low-capacity diskette become obsolete. Fuller F., Larson B., Computers: Understanding Technology (Second Edition), Assessment: Examination -70%: Coursework -30%. For example, "3" in binary cannot be put into one column. Pages 4-. A typical data bus consists of 8, 16, or separate lines. If we wanted to put a larger number in column 10^n (e.g., 10), we would have to multiply 10*10^n, which would give 10^(n+1), and be carried a column to the left. Over 100's of millions have been sold, making it the de facto standard. programmer, including the instruction set, word size, memory address Dividing (1*2^1) by 2 gives us (1*2^0), or just a 1 in binary. 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. analogous to a commercial software CD-ROM that you purchase in a store. A small program called an interrupt service routine (ISR) or interrupt handler is executed to transfer the character value f the key pressed into main memory. temperature, speed etc. In these computers, all processing Only an interrupt with a higher priority is allowed to interrupt the servicing of another. P.O. The programs written in assembly language are also machine dependent. Central Processing Unit is implementations for the various parts of a computer, focusing largely on (d) Convert the following into binary showing your working: i) 45 ii) 97, (f) What is a computer bus? All the tracks thus encountered, in the same position on each disk surface, comprise a cylinder. Digital Computers: Digital computers are mainly general purpose computers that Since each sector on the disk holds the same amount of data, more sectors mean more data storage than if all tracks had the same number of sectors. C. Interrupts; types of interrupt, interrupt priorities, interrupt handler. drive. A. Explain how information is stored in a computer Unlike competing standards, SCSI is capable of supporting eight devices, or sixteen devices with Wide SCSI. They are very large in size and use multiple processors and superior technology. Annals of Business Administrative Science, 16(2), 91-102. Saving and retrieving information from a floppy disk is slower than on a hard drive. many applications, EAROM has been supplanted by CMOS RAM backed-up by Picture, if you can, how many filing-cabinet drawers would be required to hold the millions of files of, say, tax records kept by the Internal Revenue Service or historical employee records kept by General Motors. This kind of computer is also helpful for forecasting weather reports worldwide. (a) Vacuum tubes (b) Capacitors (c) Transistors (d) Integrated circuits, Which one of the following types of computers is commonly used in offices This is inflexible and so regular ROMs are only used generally for Flash memory is used for easy and fast information storage in computers, digital cameras and home video game consoles. When data is being entered, heat from the laser produces tiny spots on the disk surface. unit, memory (ROM, RAM). But this is not practical for a system with many files or many users. You should also In 1998 Macintosh introduced its new computer, the IMAC, without a floppy disk drive. Hard Drive: There are several specific form factors that most PC motherboards use so that they can all fit in standard cases. gigabytes. @@TTA This type of programs is called machine language programs and the programming language is called machine code. o Digital Camera Used to take electronic pictures of an object. Many cartridges and cassettes have the supply and take-up reels built into the same case. Graphical user interface has some disadvantages such as. 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. Since 00110101 has eight digits, it can be divided into two blocks of four digits, 0011 and 0101. Since we divided the number by two, we "took out" one power of two. Erasable Programmable ROM (EPROM): An EPROM is a ROM that can be erased and reprogrammed. The address bus is used for communicating the physical addresses of computer memory elements/locations that the requesting unit wants to access (read/write). contains materials that are frequently examined.

The pictures next change came after about 1600 years. B. We saved magnetic tape storage for last because it has taken a subordinate role in storage technology. Electrically Alterable Read-Only Memory(EAROMs) can be modified a bit at a Box 342-01000 Thika info@mku.ac.ke Email: www.mku.ac.ke Web: Instructional Manual for BBIT Distance Learning. D. Types of computers. A little glass window is installed in the top of the They support concurrent users. Continuing the "CD" analogy, this Representations -- Datatypes and To visualize cylinder organization, pretend a cylindrically shaped item, such as a tin can, were figuratively dropped straight down through all the disks in the disk pack. Following this, the changes were frequent and the mechanical desk calculator was developed around 1800 A.D. Input Devices The EISA bus is found on Intel 80386, 80486 and early Pentium computers. Large computers have dozens or ever hundreds of disk drives. This process continues until we have a remainder of 0. A. give the user output High level language permits the user to use understandable codes using the language structure. to the C language (part 2/2), Run-time Diskettes became popular along with the personal computer. The supply reel, which has the tape with data on it or on which data will be recorded, is the reel that is changed. They can be linked to smaller to the C language (part 1/2), Introduction Microarchitecture, also known as Computer organization is a lower level, notes posted are not meant to substitute for the text Many cheaper PC's ship with power supplies I would basically describe as "disposable." Each disk in the pack has top and bottom surfaces on which to record data. Storage technologies at all levels of the storage hierarchy can be differentiated by evaluating certain core characteristics as well as measuring characteristics specific to a particular implementation. 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. D=0, so we are done, and the decimal number 163 is equivalent to the binary number 10100011. Thus, the answer is 71. Temporary Result: 01; Carry: 1, Column 2^2: 1+0=1 Add 1 from carry: 1+1=10. memory. Take the number 163. The registers shown in the block diagram above, which represents a typical computer, each have a specific purpose, which is described below. WebLecture notes of Prof David Brooks could also be referred. They are shown in the block diagram below. {HnzIxfjw^K](^$L These computers had programming languages whose vocabularies are close to the human natural language, English language. Flash memory is a type of EEPROM chip, which stands for Electronically Erasable Programmable Read Only Memory. The first in the Windows series was Windows 3.11 and the latest being Windows Vista. Cache memory is a type of very fast memory that is used to improve the speed of a Floppy Disk: Floppy disks allow information to be transported easily from one typing, recording keeping, production of financial statements, drawing, and statistics. 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. 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. consumed a lot of power and generated a lot of heat (overheating). The disk in its drive is shown in Figure 3. Video Failure Troubleshooting computational machines. 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. Zip disks are a great way to store large files and software programs. The high level languages commonly used are FORTRAN (FORmula TRANslation), BASIC (Beginner's All-purpose Symbolic Instruction Code), COBOL (COmmon Business Oriented Language). 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. Rewriting an EAROM is intended to be an This translates into putting a "1" in the 2^1 column and a "1" in the 2^0 column, to get "11". The next change came after about 1600 years. called analytical engine which was the vase for the modern digital computer. You should also refer to the lecture notes available from the textbook website. Use to put 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. The organization in this case is vertical. The commands are entered on a prompt for example the Ms Dos prompt looks like this. 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. You will see that it is the same procedure, but with sixteen digits instead of 10 or 2. System Design which includes all of the other hardware components During interpretation no object code is produced, and so the program has to be interpreted each time it is to be run. the constituent parts of the system are interconnected and how they 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. The speed of these machines was described in microseconds (1/1000, 000 of a second). -- you are required to read the textbook before (and after) each class. In most of the Hollywoods movies it is used for animation purposes. A keyboard, mouse, scanner, digital camera, variables, Implementation of functions, Dynamic 500,000 physical elements e. transistors, capacities, diodes etc per dj z(l6uHyB"C]Iie7tHDXWq@vd4KfqS)YZT&;"v%LqNm!ZTJ UWBD@^-1QA+'6b"V0s>x$*Y l(7`yAP. Performance and Code In short a COMPILER is: the translator of the source code into computer language. Since 3>1, we need to use an extra column to the left, and indicate it as "11" in binary (1*2^1) + (1*2^0). Most 4GLs are used to access databases. EAROM may be used to store critical system setup information in a non-volatile way. Brooks, Planning a Computer System, Project Stretch, 1962 What does this design consist of? A mainframe is another giant computer after the super computer and can also In binary, any digit higher than 1 puts us a column to the left (as would 10 in decimal notation). We're left with 1, which goes in 2^0, and we subtract one to get zero. Compact Disk-Writable (CD-R): A CD-R is highly effective for storing a large amount of data. retrieve, and process data", What different types of computers are there? 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. Our "new" 2^0 column now contains a1. The disk cartridges look like a floppy disk, but are slightly bigger in all dimensions. (a) Supercomputers (b) Mainframe (c) Mini computer (d) Micro 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." Governments specially use this type of computer for their different calculations and heavy jobs. Analog They are Removable disk storage units were developed for use on these machines. WebCS 135: Computer Architecture I Fall 2010 Lecture Notes. GCD210267, Watts and Zimmerman (1990) Positive Accounting Theory A Ten Year Perspective The Accounting Review, Subhan Group - Research paper based on calculation of faults. (2mks) (b). Data are stored in a small indentation in a spiral track, just like in the CD. To quote many a computer user, "I just couldn't envision how I could use all that disk space. The speed of these machines was described in nanoseconds (1/1,000,000,000 of a second). A motherboard by itself is useless, but a computer has to have one to operate. 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. Then, replace each block of four digits with its corresponding hexadecimal digit. C. Motherboard and CPU Troubleshooting Define computer data storage. Some modern Intel Core i3, i5 and i7 processor brands are split into desktop and laptop (or mobile) processors. more concrete and detailed, description of the system that involves how 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." For example, the textbook It Converts an and to perform computations on these measurements. 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. For many applications, EAROM has been supplanted by CMOS RAM backed-up by a lithium battery. P. Box 342-01000 Thika and capabilities The chipset is part of the motherboard's logic system and is usually made of two parts --the northbridge and the southbridge. This product is Personal computer users, who never seem to have enough hard disk storage space, may turn to a removable hard disk cartridge. i.e., the programs were machine dependent. Begin with one-bit binary addition: 1+1 carries us into the next column. The stored bits are usually retrieved from computers memory for manipulation by the processor. Secondary storage, sometimes called auxiliary storage, is storage separate from the computer itself, where you can store software and data on a semi permanent basis. 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. 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. The purpose is to reduce the time it takes to move the access arms of a disk pack into position. Almost all the computers used nowadays are digital computers and we will To overcome this limitation, the hexadecimal number system was developed. WebH&P2: Computer Architecture: A Quantitative Approach, 2nd edition, by Hennessy and Patterson. Also these programs written for execution in one computer cannot be used on another type of computer. The small circuitry that resulted improved the processing speed i.e. The size of a computer's cache for instance, is an organizational issue that generally has nothing to do with the ISA. Over the years, newer computers have been introduced that contain faster microprocessors. Instruction set architecture System organization (processor, memory, I/O) Micro-architecture Learn methods of evaluating performance Metrics Benchmarks Learn how to make systems go fast Pipelining, caching Parallelism Learn how to make systems less power hungry (maybe) must match the DVD region. write, because when they change their code they can create new PROMs without o Voice input device- A computer I/O device in which vocal commands 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. iv. 2 Central Processing Unit (CPU)/Processor: It is the main part of a computer system like the brain of a human being. (a) Name the two major components of the Central Processing Unit and briefly describe what each does. This places the data in diagonal bands that run across the tape rather than down its length. Storage capacity was Examples: What would the binary number 1011 be in decimal notation? vdu controller. Explain the different types of computers categorized based on size, price Their input /output capabilities were usually limited to the keyboard and or punched card input and printer and or punched cart output. x[r+&YU@lJSvB%d#QTD[/\{g\\S Ch24 - Chapter 24 solution for Intermediate Accounting by Donald E.

Lecture 11 (Mar 17): Main Memory: Design and Architecture, Presentation Research in Computer Architecture, Presentation will be uploaded next : End of class : The course ends here, schedule for final test is based on the Covid situation! While information retrieval is faster than from a floppy disk, it is still not as fast as from the hard drive. Compiler, Program 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. 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. Introduction to Computer and its components The form factor affects where individual components go and the shape of the computer's case. It is used more like a ()hard drive than as ()RAM. links that I will post to other websites. What happens when, for example, a key on the keyboard is pressed, thus generating an interrupt? D. Buses; control bus, data bus, Address Bus, SCSI, EISA, MCA, IV. keyboard controller or as output controller, e.g. The first place to start is always confirming that the power supply is operating properly. In most of the Hollywoods movies it is used for animation purposes. may be entered into a computer system. Lecture 21 (TBS): 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.
