of computer is also helpful for forecasting weather reports worldwide. Record the 0, carry the 1. The decimal number "2" is written in binary notation as "10" (1*2^1)+(0*2^0). 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. The transistor is smaller cheaper and produced less heat than vacuum tubes and consumed less power. the manufacturer. 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. 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! Motherboards have come a long way in the last twenty years. As we have already noted, magnetic tape is used primarily for backup purposes. Programming and problem The DVD drives come in 2X, 4X, etc. A program must tell the computer each of a set of tasks to perform, in a framework of logic, such that the computer knows exactly what to do and when to do it. A disk drive is a machine that allows data to be read from a disk or written on a disk. Region one is USA and Canada, while Europe and Asia is region two. many applications, EAROM has been supplanted by CMOS RAM backed-up by Random-access storage media refers to magnetic core, semiconductor, thin film, and bubble storage. (2mks) (b). 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. 6.823 is a study of the evolution of computer architecture and the factors influencing the Windows is a Graphical user interface based operating system. An interrupt is a signal from some device or source seeking the attention of the processor. ROM package, through which you can actually see the chip that holds the The laser beam is set to two different intensities, strongest for reading the underlying silver layer. Put 1 in the 2^3 column, and 0 in 2^4 and 2^5. The following are the different types of interrupt that could occur; There is a special register in the CPU called the interrupt register. The disk in its drive is shown in Figure 3. We learned earlier that there is a 1 in the 2^0 column if the number is odd. % (a) Vacuum tubes (b) Capacitors (c) Transistors (d) Integrated circuits, Which one of the following types of computers is commonly used in offices C. Interrupts; types of interrupt, interrupt priorities, interrupt handler. For many applications, EAROM has been supplanted by CMOS RAM backed-up by a lithium battery. 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. This is Topics may include: instruction set design; processor micro-architecture and Course Info Instructors the required results faster than human beings. MCA, or the Micro Channel bus, was a competition for ISA bus. Begin by thinking of a few examples. 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 ? Need sound recording This indicates the speed at which the CD can transfer data to the CPU -the higher the X factor, the faster the CD. the most flexible type of ROM, and is now commonly used for holding BIOS When buying a computer the speed of the CD-ROM drive is advertised using an "X" factor, like 12X, or 24X. Data thus saved can be restored to the hard disk later if needed. must match the DVD region. 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. Input unit D=0, so we are done, and the decimal number 163 is equivalent to the binary number 10100011. 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. (7mks). RDRAM (Rambus DRAM) involves a new memory design that achieves a higher data transfer speeds but it is expensive to manufacture. Several disks can be assembled into a disk pack. xH2Z@Qh>$p+![r5V28U<>hc`Ko3e7F^(CRz.]kA/()U&JxQ*r"?Da:)oW6LW8it^0!m OzDH When you hear reference to a "flash BIOS" or doing a BIOS upgrade Making this algorithm a bit more formal gives us: This algorithm is a bit awkward. Email: info@mku.ac time, but writing is a slow process and uses non-standard voltages (usually D. Buses; control bus, data bus, Address Bus, SCSI, EISA, MCA, IV. These computers were mostly computational machines. computer. The system unit is often called the Central Processing Unit. The sector method is used for diskettes as well as disk packs. 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. To understand binary numbers, begin by recalling elementary school math. In the sector method each track is divided into sectors that hold a specific number of characters. The disk cartridges look like a floppy disk, but are slightly bigger in all dimensions. This is sometimes referred to as direct overwriting and can be repeated several thousand times per disc. class. 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 Dividing 80 by 2 gives 40. came UNIVAC (universal automatic computers). Now we need to do the remaining digits. more emphasis on the more technical aspects of computing such as Both types of RAM are volatile, meaning that they lose their contents when the power is turned off. A different ISR is provided for each different source of interrupt. 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. Not all computer hardware uses voltage, however. 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. vdu controller. Electrically Erasable Programmable ROM (EEPROM): The next level of A concept of using several small disks that work together as a unit is called a redundant array of inexpensive disks, or simply RAID. They can be linked to smaller Lecture 21 (TBS): Flash memory is used for easy and fast information storage in computers, digital cameras and home video game consoles. Record the 1. the maim memory, and works by storing the most frequently or recently used instructions called a mother board. Fuller F., Larson B., Computers: Understanding Technology (Second Edition), Assessment: Examination -70%: Coursework -30%. The processor contains the control unit and the arithmetic/logic unit(ALU). DDR SDRAM (Double Data Rate SDRAM) can transfer data twice as fast as SDRAM because it reads data twice during each clock cycle. 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. Arithmetic operations these operations are addition, subtraction, The speed of these machines was described in milliseconds (1/1000 of a second). We know that: and so on. Since we divided the number by two, we "took out" one power of two. For example, "3" in binary cannot be put into one column. level languages and provision of system software with the computer. 3. 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. If I had to choose one part to blame the majority of intermittent failures in cheap PC's on, it would be the power supply. In addition, the EISA can accommodate a 16-bit ISA card in the first row. This generation marked the origin of mini computers in use today. Temporary Result: 001; Carry: 1, Column 2^3: 1+1=10. ); it can be written to, but only support concurrent users. implementations for the various parts of a computer, focusing largely on microcomputer is called a microprocessor. A Bus is a set of parallel wires connecting two or more components in a computer. Writing takes place in a single pass of the focused laser beam. Now I can imagine even the extra disk filling up.".

A hard disk is a metal platter coated with magnetic oxide that can be magnetized to represent data. Most 4GLs are used to access databases. Personal computer users have the option of purchasing their own tape backup system, to be used on a regular basis for copying all data from hard disk to a high-capacity tape. You should also refer to the lecture notes available from the textbook website. 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) of Maryland. Users plugged components like floppy drive controllers and ()memory into the slots. P.O. Four's column: Now we can subtract 1 from 81 to see what remainder we still must place (80). You can also use software to edit the items you Micro Channel Architecture (MCA) was introduced by IBM in 1987. For example, a transistor with five volts would be considered "on", while a transistor with no voltage would be considered "off." We saved magnetic tape storage for last because it has taken a subordinate role in storage technology. 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 i3 is solely a dual-core CPU; the i5 offers dual-and quad-core choices; and the i7 is split into dual-, quad-and six-core choices. A disk pack is mounted on a disk drive that is a separate unit connected to the computer. Assembly language is translated into machine code using an assembler before they can be executed. The external components of a computer are called peripheral devices which include input and output. Once the access arms are in position, they are in the same vertical position on all disk surfaces. Super computers are biggest in size, the most expensive in price than any other is Explain the evolution of computing technology and the technological WebBIT 1101 Computer Architecture complete lecture notes for first years and all - P. Box 342-01000 - Studocu. Erasable Programmable ROM (EPROM): An EPROM is a ROM that can be Next, add {(2+4) +1} (the one is from the carry)=7, which is put in the 10's column of the sum. The binary system works under the exact same principles as the decimal system, only it operates in base 2 rather than base 10. Optical storage technology is categorized according to its read/write capability. Let's look at how this can help us convert from decimal to binary. Computer architecture or digital computer organization is the conceptual design and fundamental operational structure of a computer system. A key advantage of a tape backup system is that it can copy the entire hard disk in minutes, saving you the trouble of swapping diskettes in and out of the machine. Color laser printers are still fairly expensive. A 4GL is an aid which the end user or programmer can use to build an application without using a third generation programming language. by "flashing", this refers to reprogramming the BIOS EEPROM with a special digital computers. Obviously this is much more useful than a regular PROM, but it does require the erasing light. Obviously this is much more useful than a regular 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. The first calculating device, which was used 2000 years ago was called %PDF-1.3 A mainframe is another giant computer after the super computer and can also The benefits of secondary storage can be summarized as follows: These benefits apply to all the various secondary storage devices but, as you will see, some devices are better than others. Mainframe computers They are smaller than the main frame but bigger than microcomputers. ); it can be written to, but only once. Iomega The most popular removable disk media is the Zip drive from ()(Figure 3). to the C language (part 2/2), Run-time This is significant data insurance. The arithmetic/logic unit(ALU) plays two roles. Data on the track is accessed by referring to the surface number, track number, and sector number where the data is stored. The code written by the programmer is called the source code and the compiled code is called the object code. Electrically Alterable Read-Only Memory(EAROMs) can be modified a bit at a Instead of using the digits 0-9, we only use 0-1 (again, if we used anything larger it would be like multiplying 2*2^n and getting 2^n+1, which would not fit in the 2^n column. Web6.823 is a course in the department's "Computer Systems and Architecture" concentration. requiring expensive equipment. The shape and layout of a motherboard is called the form factor. The chipset is part of the motherboard's logic system and is usually made of two parts --the northbridge and the southbridge. Furthermore, graphics images and audio and video files require large file capacities. They are used for complex tasks requiring a lot of computational power. This product is analogous to a commercial software CD-ROM that you purchase in a store. Our running total now stands at a[3]=0, a[2]=0, a[1]=1, and a[0]=1. A little glass window is installed in the top of the The second generation saw the introduction of more complex ALU and CPU, the use of high level languages and provision of system software with the computer. Hexadecimal is more compact than binary but is still based on the digital nature of computers. The first IBM PC motherboard had only a processor and card slots. We can continue in this manner until there is no remainder to place. Then we just put this into columns. Typically, a CD ROM holds up to 650 MB of information. Governments specially use this type of computer for their different The EISA bus is found on Intel 80386, 80486 and early Pentium computers. )wG-$b!vQs@K%quHPg$*^SQ2W9DmwC~#p2Yq$

Data access time was measured in micro-seconds. Removable disk storage units were developed for use on these machines. This is inflexible and so regular ROMs are only used generally for programs that are static (not changing often) and mass-produced. 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. At the beginning of each fetch-execute cycle, the interrupt register is checked. Fuller F., Larson B., Computers: Understanding Technology(Second Edition) It interprets the instructions in the program and executes one by one. They can be used as servers in companies. In most of these cases one deals with Data Base Management Systems (DBMS). This type of programs is called machine language programs and the programming language is called machine code. Invention of IC revolutionalised electronics and started the error of micro-electronics. A set of programs associated with the operation of a computer. This computer is commonly used in big hospitals, air line reservations companies, and many other huge companies prefer mainframe because of its capability of retrieving data on a huge basis. C. The motherboard; form factor, sockets and slots It is inefficient for humans to use binary, however, because it requires so many digits to represent a number. The commands are entered on a prompt for example the Ms Dos prompt looks like this. compared to real read-write memory (RAM) where rewriting is done often many A typical data bus consists of 8, 16, or separate lines. NB: Nowadays most of the general purpose software is being sold as a complete software suites such as Microsoft office or Lotus SmartSuite. Operators, Von To convert the decimal number 75 to binary, we would find the largest power of 2 less than 75, which is 64. (a) Supercomputers (b) Mainframe (c) Mini computer (d) Micro computer. advancement in computer architecture to current technologies Hardware: input and output devices, backup storage, central processing Hard disk for mainframes and minicomputers may be as large as 14 inches in diameter. Zip disks are a great way to store large files and software programs. Computers have continued to decrease in size but the processing power has Winchester disk assemblies are put together in clean rooms so even microscopic dust particles do not get on the disk surface. product problem - assembly code, Introduction 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. In such a system a task is broken down and shared among processes for faster execution. Micro computers Many disk devices, however, do not record data on the top of the top platter or on the bottom of the bottom platter. During interpretation no object code is produced, and so the program has to be interpreted each time it is to be run. very low i. Direct-access storage allows you to access the 125th record without first having to read the 124 records in front of it. 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. Since Assembly language is machine dependent each type of computer has its own assembler. Two's column: Dividing 162 by 2 gives 81. Floppy Disk: Floppy disks allow information to be transported easily from one computer to another they have limited storage capacity, generally 1.44 MB. Intro to LC3, Low-level Output devices This new feature enables different reading modes for our document viewer. Newer technologies such as DDR II and SLDRAM (Synclink DRAM) are emerging. It Organization: Cache, Main Memory, It Converts an Electrically Erasable Programmable ROM (EEPROM): The next level of erasability is the EEPROM, which can be erased under software control. We start by looking at the different types of computer components and how they interact during basic computer operations. For example, the textbook Super computers are biggest in size, the most expensive in price than any other is classified and known as super computer. There are two types of interface that can be provided by the operating system. Looking at this in columns. A compiler is a program that translates high level language instructions into machine code. The processor also stores the instructions being currently executed into the main memory. Flash memory is a type of EEPROM chip, which stands for Electronically Erasable Programmable Read Only Memory. consumed a lot of power and generated a lot of heat (overheating). Number To overcome this limitation, the hexadecimal number system was developed. Our "new" 2^0 column now contains a1. They are slower and less costly compared to mainframe computers but more powerful, The pictures The p ro c essor ; Ari th m eti c an d Logi c Unit , C ontro l U n it , sy st em 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. Computer systems are constructed of digital electronics. The first motherboards held very few actual components. Instead of typing a command or file name, selection is achieved by moving a pointer with a mouse and clicking a mouse button. 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." o Scanner allows you to scan documents, pictures, or graphics and view Some of the other standards include: The socket for the microprocessor determines what kind of Central Processing Unit (CPU) the motherboard uses. The cost of computers decreased and the speed increased. Explain the fundamental difference between computer hardware and The stored bits are usually retrieved from computers memory for manipulation by the processor. Each new track and new surface, however, would require movement of the access arms, a relatively slow mechanical process. It controls and monitors the running of application programs. B. Printout is permanent window for a specified period of time, which will erase the EPROM and allow it A 4.7 GB side of a DVD can hold 135 minutes top quality video with 6 track stereo. The data is recorded on the tracks that can be accessed by one positioning of the access arms-that is, on one cylinder. For Every effort will be made to get the notes on the web prior to the lecture. Video failure can also be due to motherboard failure or to external interference, when it comes to poor image quality. may be entered into a computer system. 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 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. This is mostly hard drives and removable media such as floppy disks, optical media (CD ROM) etc. This is similar to the way a CD-ROM recorder A way to organize data on a disk pack is the cylinder method. abacus and the improvements in the calculating device in that age were slow. computational machines. 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. These are devices which are used to store huge information for future use. Programmable ROM (PROM): This is a type of ROM that can be programmed using special equipment (a PROM programmer. and that this is equivalent to (1*2^1)+(1*2^0). WebH&P2: Computer Architecture: A Quantitative Approach, 2nd edition, by Hennessy and Patterson. Different industries also use this huge computer for designing their products. Memory size expanded up to several MB and speed was 10 times faster. Central Processing Unit is chip(IC). In Fig 1.2, the notches we have marked as A, are used for the ejector clip on the DIMM slot (see later). These patterns of "on" and "off" stored inside the computer are used to encode numbers using the binary number system. Cache memory When you hear reference to a "flash BIOS" or doing a BIOS upgrade by "flashing", this refers to reprogramming the BIOS EEPROM with a special software program. It is the main part of a computer system like the brain of a human being. designing their products. C. Motherboard and CPU Troubleshooting They are known for von Newmans design i.e. II. The processor and main memory of a PC are commonly held on a single board 2 0 obj Announcements Contact Information Lecture Notes: Lectures marked TBU will be updated as semester progresses.

The set of instructions is often called a program or, if the set is particularly large and complex, a system. Table of Contents. 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. Hard drive failures are generally pretty easy to troubleshoot, in part because the operating system will include tools to report on the hard drive's reliability when it's accessible.. Video Failure Troubleshooting Special storage locations called registers are included in this circuitry to hold information temporarily while it is being decoded or manipulated. The CPU of a 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. o Voice input device- A computer I/O device in which vocal commands 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. Eight's column: We can divide by two again to get 20. A bit is used to represent information in the computer. So the number "193" is 1-hundreds plus 9-tens plus 3-ones. A given amount of data that takes up 1 inch of a track on the inside of a disk might be spread over several inches on a track near the outside of a disk. 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. However, only one read/write head can operate at any one time. memory. Some systems feature dual BIOS, which provides a backup in case one fails or in case of error during updating. When the human race started doing some trade, it felt a need for a calculating 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. Continuing the "CD" analogy, this Then, replace each block of four digits with its corresponding hexadecimal digit. The micro chip technology has enabled reduction of size of. The movies are made in two formats, each with their own coding. The following program written in BASIC language is to add two given numbers. In 1833, Prof. Charles Babbage, the father of the computer, developed a machine called analytical engine which was the vase for the modern digital computer. to the C language (part 1/2), Introduction Cache memory is a type of very fast memory that is used to improve the speed of a The fifth generation is still a state of the art technology that relies on predictions and further technological refinements. implemented in a single piece of silicon device known as a computer chip. The read/write head on the end of the access arm hovers just above the track but does not actually touch the surface. EAROM may be used to store critical system setup information in a non-volatile way. Dividing (1*2^1) by 2 gives us (1*2^0), or just a 1 in binary. To provide an in-depth presentation of computer hardware and software with A graphical user interface (GUI) allows the user to interact with the system using Windows, Icons, Menus, and Pointers to control the operating system. 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. The 3-1/2 inch diskette has the protection of a hard plastic jacket, a size to fit conveniently in a shirt pocket or purse, and. The CPU is connected to the main memory by three separate buses. Older Zip disks hold 100MB, newer ones hold 250MB and cost $8-$10 a piece (Floppies hold 1.4MB and cost around $2). To appreciate this, suppose you had an empty disk pack on which you wished to record data.
