o Video Capture Card Usually place inside the computer's case. In most of the Hollywoods movies it is used for animation purposes. They are more susceptible to physical damage and viruses than the hard 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. The data is recorded on the tracks that can be accessed by one positioning of the access arms-that is, on one cylinder. 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. The p ro c essor ; Ari th m eti c an d Logi c Unit , C ontro l U n it , sy st em Annals of Business Administrative Science, 16(2), 91-102. may be entered into a computer system. When you hear reference to a "flash BIOS" or doing a BIOS upgrade Micro computers WebUniversity of Toronto Department of Computer Science 2004-5 Steve Easterbrook. ); it can be written to, but only However, this is not the only approach possible. Compact Disk Read Only Memory (CD ROM): CD ROMs are read only storage medium. Diskettes became popular along with the personal computer. The lecture They were huge in size and occupy a room. Continuing the "CD" analogy, this technology is analogous to a reusable CD-RW. Representations -- Datatypes and DVD movies are made in two "codes." Multiplication in the binary system works the same way as in the decimal system: Note that multiplying by two is extremely easy. Their input /output capabilities were usually limited to Special storage locations called registers are included in this circuitry to hold information temporarily while it is being decoded or manipulated. While information retrieval is faster than from a floppy disk, it is still not as fast as from the hard drive. j!)+v%""s!-+ 2MYI9RVgJm +9 vy?nW?n%}GQdd Ny= z-I9GZI3)hKrhIY$W. Removable disk storage units were developed for use on these machines. Consider the addition of decimal numbers: We begin by adding 3+8=11. They are They can be linked to smaller computers and handle hundreds of users they are also used in space exploitation. 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. At the beginning of each fetch-execute cycle, the interrupt register is checked. The code written by the programmer is called the source code and the compiled code is called the object code. Programmable ROM (PROM): This is a type of ROM that can be programmed In assembly language mnemonic codes are used to develop program for problem solving. Hexadecimal works in the same way as binary and decimal, but it uses sixteen digits instead of two or ten. To provide an in-depth presentation of computer hardware and software with more emphasis on the more technical aspects of computing such as troubleshooting and upgrading computers. Nguyen Quoc Trung. first one is smaller than, equal to or greater than the second item. 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. of Maryland. increased. III. Static RAM does not need to be refreshed, which makes it faster; but it is also more expensive than dynamic RAM. They used magnetic tape. notes that you will be expected to read before class. (2017). level languages and provision of system software with the computer. These are devices which are used to store huge information for future use. for faster execution. When the CPU wishes to access a particular memory location, it sends this address to memory on the address bus. This is also true when reading punched cards or paper tape. Consists of programs that control operations of the computer and enable user to make efficient use of computers. Software It is the main part of a computer system like the brain of a human being. The processor communicates and controls a peripheral device through an I/O or device controller. read from them many times. We start by looking at the different types of computer components and how they interact during basic computer operations. Web: mku.ac. Mainframe computers 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. The width of an address bus, along with the size of addressable memory elements, determines how much memory can be accessed. usually called personal computers since they are designed to be used by A data bus provides a bi-directional path for moving data and instructions between system components. This is even, so we put a 0 in the 8's column. Governments specially use this type of computer for their different These computers had programming languages whose vocabularies are close to the human natural language, English language. A single bit alone cannot represent a number, letters or special characters, to represent information; bits are combined into groups of eight. The first in the Windows series was Windows 3.11 and the latest being Windows Vista. They are shown in the block diagram below. stream general purpose software, integrated packages and software suites. 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. for using the C to LC3 size IC, hence the size reduced. A disk pack has a series of access arms that slip in between the disks in the pack. to the C language (part 2/2), Run-time 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. 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. changed. The size of a computer's cache A. Therefore, it would shift you one column to the left. contains materials that are frequently examined. 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. D=0, so we are done, and the decimal number 163 is equivalent to the binary number 10100011. ROM package, through which you can actually see the chip that holds the next change came after about 1600 years. Box 342-01000 Thika info@mku.ac.ke Email: www.mku.ac.ke Web: Instructional Manual for BBIT Distance Learning. reliable and expensive than micro computers. Today, motherboards typically boast a wide variety of built-in features, and they directly affect a computer's capabilities and potential for upgrades. The first IBM PC motherboard had only a processor and card slots. AxgyL@0#jE:3tBP20zivoKJ]2w\$wkNIkyDXQwsACvc; hq W j Sometimes you can spot a blown capacitor on a motherboard, but it's not a common problem. The speed of these machines was described in milliseconds (1/1000 of a second). Windows is a Graphical user interface based operating system. Introduction to Computer and its components This demanding shopping list is a description of the optical disk, like a CD. temperature, speed etc. 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). 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. The explosive growth in storage needs has driven the computer industry to provide cheaper, more compact, and more versatile storage devices with greater capacity. blueprint and functional description of requirements and design They are slower and less costly compared to mainframe computers but more powerful, reliable and expensive than micro computers. Data access This product is When you play movies, your hardware (MPEG decoder. The processor has the following functions: It controls the transmission of data from input devices to memory; It processes the data held in main memory; It controls the transmission of information from main memory to output o Voice input device- A computer I/O device in which vocal commands The disk cartridges look like a floppy disk, but are slightly bigger in all dimensions. Need sound recording This change further decreased the size, heat output and the maintenance complexity of the computers while increasing its speed. 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. The two components (hardware, software) will be discussed later in other When you store a file on tape, the 125th record cannot be read until the 124 records in front of it are read. WebComputer Architecture Computer architecture, like other architecture, is the art of determining the needs of the user of a structure and then designing to meet those needs Computer System Architecture Notes: Computer This is inflexible and so regular ROMs are only used generally for This categories are based on size, price and capabilities. designing their products. These computers were mostly computational machines. programmer, including the instruction set, word size, memory address computers and handle hundreds of users they are also used in space exploitation. memory. Now we need to do the remaining digits. Here is a link to some online notes that I found to be well powerpoint format) I will post detailed notes that will go into 6.823 is a study of the evolution of computer architecture and the factors influencing the Bus size means the number of bits that can be transmitted together. (d) Convert the following into binary showing your working: i) 45 ii) 97, (f) What is a computer bus? Some of the other standards include: The socket for the microprocessor determines what kind of Central Processing Unit (CPU) the motherboard uses. discuss the detailed working and components of these computers in subsequent sections of ALL, Explain the different types of computers categorized based on size, price 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. ()Instruction set architecture, or ISA, is the abstract image of a computing ()system that is seen by a machine language (or assembly language()programmer, including the instruction set, word size, memory address ()modes, processor registers, and address and data formats. Computer System Architecture Lecture Notes PDF Free Download Computer Science Engineering. 2. implementations for the various parts of a computer, focusing largely on programs that are static (not changing often) and mass-produced. The outer gold layer is semi transparent, to allow reading of the underlying silver layer. 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. The DVD drives will not replace the magnetic hard disks. The definition from the Merriam-Webster Dictionary : "one that computes; specifically : a programmable electronic device that can store, Since we already knew how to convert from binary to decimal, we can easily verify our result. Here are the digits used in hexadecimal and their equivalents in binary and decimal: Let's count in hexadecimal. To read the data, the laser scans the disk, and a lens picks up different light reflections from the various spots. Commands tell the computer Decode translate the program instruction into commands that the Purpose of the course programs. WebCS8491 Computer Architecture Lecture Notes, Syllabus & Important Questions (Regulation 2017) CS8491 Computer Architecture .Pdf DOWNLOAD(Including Syllabus, Lecture Notes, 2 Marks & 16 Marks with Year Wise Question Paper Collections) We are very Happy to Provide your all Requirements in a single file 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. Subtract 8 from 11 to get 3. very low i. The following program written in BASIC language is to add two given numbers. 2. Lecture 21 (TBS): 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. 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. Knowledge Network of Toyota. Next, add {(2+4) +1} (the one is from the carry)=7, which is put in the 10's column of the sum. The number 81 in binary would also have a 1 in the 2^0 column. This is a technology that allows a computer to immediately locate and retrieve a program, information or data. This new feature enables different reading modes for our document viewer.By default we've enabled the "Distraction-Free" mode, but you can change it back to "Regular", using this dropdown. multiple processor system with parallel processing. Record the 1. Chapter 1- Fundamentals of Computer Design. Tape now has a limited role because disk has proved the superior storage medium. computer can process Obviously this is much more useful than a regular PROM, but it does require the erasing light. Central processing unit (CPU) or processor The processor contains the control unit and the arithmetic/logic unit(ALU) and the system clock. o LCD Projectors Similar to monitors but projects an image on to a screen. They are smaller than the main frame but bigger than microcomputers. multiplication and division.. A computer is an electronic device capable of executing instructions, developed A set of programs associated with the operation of a computer. 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. They were times per second! In 1998 Macintosh introduced its new computer, the IMAC, without a floppy disk drive. Since 00110101 has eight digits, it can be divided into two blocks of four digits, 0011 and 0101. B. 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." Picture Window theme. Since the western alphabet contains only ten digits, hexadecimal uses the letters A-F to represent the digits ten through fifteen. For The supply reel, which has the tape with data on it or on which data will be recorded, is the reel that is changed. A. To provide an in-depth presentation of computer hardware and software with 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. Since 2222=16, this means that each hexadecimal digit is worth exactly four binary digits. You should also refer to the lecture notes available from the textbook website. EAROM Large computers have dozens or ever hundreds of disk drives. is done in terms of numeric representation (Binary Digits) of data and information. The Continue counting: 10, 11, 12, 13, 14, 15, 16, 17 18, 19, 1A, 1B, 1C, 1D, 1E, 1F. The tubes consumed a lot of power and generated a lot of heat (overheating). Record the 0, carry the 1. Personal computer users find accessing files on a hard disk is significantly faster and thus more convenient than accessing files on a diskette. D. Hard Drive Failure Troubleshooting, V. Input and output devices and interrupts. Flash memory is used for easy and fast information storage in computers, digital cameras and home video game consoles. However, only one read/write head can operate at any one time. To appreciate this, suppose you had an empty disk pack on which you wished to record data. Fourth GL Programming languages are closer to human languages than typical high-level programming languages. chapters. generation saw the introduction of more complex ALU and CPU, the use of high There is also the possibility of errors introduced by software. (2mks) (b). drive. A computer has to main components; Explain the fundamental difference between computer hardware and Operators, Von the way by which the central processing unit (CPU) performs internally The decimal number "2" is written in binary notation as "10" (1*2^1)+(0*2^0). Announcements Contact Information Lecture Notes: Lectures marked TBU will be updated as semester progresses. The truth is, of all the four subsystems represented in this table, hard drives are probably the most reliable. a lithium battery. They are Chapter Objectives At the end of the chapter the learner shall be able to; Internal components are contained in the System Unit. 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. Record the 0 in the ones column, and carry the 1 to the twos column to get an answer of "10." Control lines are used to ensure that access to and use of the data and address buses by the different components of the system does not lead to conflict. This is useful for companies that make their own ROMs from software they They are of advanced technology i. the micro era based on large scale ntz0_u.E5Yo!& Let's try the number D=55. notes posted are not meant to substitute for the text Iomega The most popular removable disk media is the Zip drive from ()(Figure 3). We can easily see that the number 3= 2+1. Then we just put this into columns. 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).

But estimating future needs is rarely easy. For the sake of simplicity, throw away the remainder. Computer architecture or digital computer organization is the conceptual This fact makes it easy to convert between binary and hexadecimal. Table of Contents. 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. Such a disk cannot, obviously, be used for your files, but manufacturers can use it to supply software.

Almost all the computers used nowadays are digital computers and we will Power Supply Troubleshooting The main features which distinguish one processor from another and which determine the performance of each are; In addition the CPU contains circuitry controlling the interpretation and execution of instructions. computer. Fuller F., Larson B., Computers: Understanding Technology (Second Edition), Assessment: Examination -70%: Coursework -30%. In the sector method each track is divided into sectors that hold a specific number of characters. Hardware and software The processor and main memory of a PC are commonly held on a single board called a mother board. We know that: and so on. Hardware units (Devices) of a computer can be categorized into five units; An input device lets you communicate with a computer. `P|U`J]Jsf/=*mhA*x+*v PuHMf yoPpile.K9^bEjed*csaE'ZaT1w@gTo7t Computer Organization and Architecture lecture notes include computer organization and architecture handwritten notes, computer organization and architecture book, computer organization and architecture courses, computer organization and architecture syllabus, computer organization and architecture (0's and l's). 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. Random-access storage media refers to magnetic core, semiconductor, thin film, and bubble storage. For example, putting ten in the 10^0 column is impossible, so we put a 1 in the 10^1 column, and a 0 in the 10^0 column, thus using two columns. It is designed to perform a specific function and cannot be changed. design and fundamental operational structure of a computer system. WebComputer architecture, like other architecture, is the art of determining the needs of the user of a structure and then designing to meet those needs as effectively as possible within economic and technological constraints. F.P. Typically the clock pulse rate in 2000 is around 500 megahertz (million cycles per second). A little glass window is installed in the top of the Different industries also use this huge computer for designing their products. the constituent parts of the system are interconnected and how they Floppy Disk: Floppy disks allow information to be transported easily from one process millions of instruction per second and capable of accessing billions of 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. drive. The first motherboards held very few actual components. 10100011=(1*2^0)+(1*2^1)+(1*2^5)+(1*2^7)=1+2+32+128= 163. 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 Email: info@mku.ac Each disk in the pack has top and bottom surfaces on which to record data. Each new track and new surface, however, would require movement of the access arms, a relatively slow mechanical process. Memory allocation: malloc and Stack and Allocation of C II. 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. They are mainly used for presentations. To understand binary numbers, begin by recalling elementary school math. RDRAM (Rambus DRAM) involves a new memory design that achieves a higher data transfer speeds but it is expensive to manufacture. works by letting you "burn" programs onto blanks once and then letting you Data access time was measured in micro-seconds. computers are mainly used for scientific and engineering applications. 2kb and speed of processing was also very low. Since Assembly language is machine dependent each type of computer has its own assembler. Used to put printed pictures and text into a computer. Super computers are biggest in size, the most expensive in price than any other is software came UNIVAC (universal automatic computers). Cache memory is a type of very fast memory that is used to improve the speed of a computer doubling it in some cases. (a). The number 76, for example, takes only two digits to write in decimal, yet takes seven digits to write in binary (1001100). To execute an assembly language program it should first be translates into an equivalent machine language program. At present, computer users do not write programs using machine language. Then, replace each block of four digits with its corresponding hexadecimal digit. A network operating system is required when a number of computers are connected together to form a network. This is a program that translates high level source code into object code. Memory size expanded up to several MB and speed was 10 times faster. This process continues until we have a remainder of 0. In binary, any digit higher than 1 puts us a column to the left (as would 10 in decimal notation). There are several specific form factors that most PC motherboards use so that they can all fit in standard cases. software. interoperate in order to implement the ISA. Color laser printers are still fairly expensive. x[r+&YU@lJSvB%d#QTD[/\{g\\S WebLecture notes of Prof David Brooks could also be referred. 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).
