They are shown in the block diagram below. It controls and monitors the running of application programs. Once the data has been processed by the processor, the data can be displayed by the output devices. Word size also determines the speed of the computer. Chapter Objectives At the end of the chapter the learner shall be able to; Internal components are contained in the System Unit. This is inflexible and so regular ROMs are only used generally for programs that are static (not changing often) and mass-produced.

We saved magnetic tape storage for last because it has taken a subordinate role in storage technology. process millions of instruction per second and capable of accessing billions of first one is smaller than, equal to or greater than the second item. may be used to store critical system setup information in a non-volatile way. Personal computer users find accessing files on a hard disk is significantly faster and thus more convenient than accessing files on a diskette. There are several specific form factors that most PC motherboards use so that they can all fit in standard cases. Fuller F., Larson B., Computers: Understanding Technology(Second Edition) Record the 0 in the ones column, and carry the 1 to the twos column to get an answer of "10." dynamic data structures in C, Instructions Applications software packages sometimes include a dozen diskettes or more; all these could fit on one optical disk with plenty of room to spare. Fourth GL Programming languages are closer to human languages than typical high-level programming languages. discuss the detailed working and components of these computers in subsequent sections of Each byte can be used to represent a number, letter or special character. must begin on a clock pulse, although some activities take more than one clock pulse to complete. Every effort will be made to get the notes on the web prior to the lecture. HARDWARE DESIGN OF DSP PROCESSORS IN FPGA. 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. D. Hard Drive Failure Troubleshooting, V. Input and output devices and interrupts. the most flexible type of ROM, and is now commonly used for holding BIOS When the human race started doing some trade, it felt a need for a calculating 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. 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. We're left with 1, which goes in 2^0, and we subtract one to get zero. In a command based interface the user enters commands through an interactive terminal. The CPU and the RAM are two main components that can be upgraded to increase a computer's speed, though doing this may require replacing the motherboard as well. The design of these computers was based on VLSI (very large scale integration) technology, the micro chip technology that gave rise to the smaller computers known as the micro computers in use today. These are devices which are used to store huge information for future use. But estimating future needs is rarely easy. The input and output devices are discussed in details in chapter 2 of the module. Graphical user interface has some disadvantages such as. WebCS385 Computer Architecture, Lecture 1 Reading: Patterson & Hennessy - Chapter 1 Topics: Introduction, Computer Architecture = Instruction Set Architecture + Machine Inside the computer They were huge in size and occupy a room. Microsoft, Borland, IBM, and other companies make 5GL visual programming products for developing applications in Java, for example. 500,000 physical elements e. transistors, capacities, diodes etc per A network operating system is required when a number of computers are connected together to form a network. 2. Knowledge Network of Toyota. Rewriting an EAROM is intended to be an infrequent operation -most of the time the memory is used as a ROM. Most mainframe computers have 32-bit words. Here we are blurring the line a bit between what "read-only" This kind and data so that it will be very fast to retrieve them again. 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!

The width of an address bus, along with the size of addressable memory elements, determines how much memory can be accessed. Can hold up to 700MB of information. Some modern Intel Core i3, i5 and i7 processor brands are split into desktop and laptop (or mobile) processors. Video Failure Troubleshooting floppy disk controller. Ultraviolet light of a specific frequency can be shined through this window for a specified period of time, which will erase the EPROM and allow it to be reprogrammed again. )fb1{`BF Twelve would be 12*10^0, or 10^0(10+2), or 10^1+2*10^0, which also uses an additional column to the left (12). Number Chapter 3- Instruction Central Processing Unit is implemented in a single piece of silicon device known as a computer chip. 2 Input Devices This is even, so we put a 0 in the 8's column. Final result: 11001. To overcome the performance limitations of SDRAM, two competing technologies have been developed. The binary number system is a method of storing ordinary numbers such as 42 or 365 as patterns of 1's and 0's. Cache memory is a type of very fast memory that is used to improve the speed of a computer doubling it in some cases. The registers shown in the block diagram above, which represents a typical computer, each have a specific purpose, which is described below. Direct-access storage allows you to access the 125th record without first having to read the 124 records in front of it. WebLecture #4-5: Computer Hardware (Overview and CPUs) CS106E Spring 2018, Young In these lectures, we begin our three-lecture exploration of Computer Hardware. Color laser printers are still fairly expensive. II. Since 0011=3 and 0101=5, the corresponding hexadecimal number is 35. http://www.math.grin.edu/~rebelsky/Courses/152/97F/Readings/student-binary, Answers 1 255 2. a) 3 b) 6 3. a) 110010 4. a) 1011 5 a) 13, c) 10 d) 65 b) 1001011 d) 1000011c) 11111010. Next, add {(2+4) +1} (the one is from the carry)=7, which is put in the 10's column of the sum. Fault Diagnosis A keyboard, mouse, scanner, digital camera, A mainframe is another giant computer after the super computer and can also process millions of instruction per second and capable of accessing billions of data .They are physically very large in size with very high capacity of main memory. In binary, any digit higher than 1 puts us a column to the left (as would 10 in decimal notation). A. P. Box 342-01000 Thika This fact makes it easy to convert between binary and hexadecimal. keyboard controller or as output controller, e.g. An input device lets you communicate with a computer. They are usually called personal computers since they are designed to be used by individuals. An operating system acts as foundation on which other application software can be installed. The disk in its drive is shown in Figure 3. This is mostly hard drives and removable media such as floppy disks, optical media (CD ROM) etc. Most 4GLs are used to access databases. Particularly step 3, "filling in the zeros." When you remove the DIMM memory module from its packaging hold it by the edges, try not to touch the gold coloured contacts, as this can damage the memory. An interrupt is a signal from some device or source seeking the attention of the processor. Memory size expanded up to several MB and speed was 10 times faster. It is designed to perform a specific function and cannot be changed. The IBM 360 is an example of third generation computers. 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. I. Web1 cache.1 361 Computer Architecture Lecture 14: Cache Memory cache.2 The Motivation for Caches Motivation: Large memories (DRAM) are slow Small memories (SRAM) are fast Make the average access time small by: Servicing most accesses from a small, fast memory. Our "new" 2^0 column now contains a1. Our running total now stands at a[3]=0, a[2]=0, a[1]=1, and a[0]=1. This computer is not used as a PC in a home neither by a student in a college. 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. 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. Computer hardware refers to the physical components of a computer such as the They are blueprint and functional description of requirements and design In Fig 1.2, the notches we have marked as A, are used for the ejector clip on the DIMM slot (see later). If we put the 1 in the 2^0 column, we have 162 left, and have to decide how to translate the remaining digits. 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. For You should also refer to the lecture notes available from the textbook website. We know that: and so on. a similar course at Univ. Take the number 163. This opens the possibility to write data in two layers. They are of advanced technology i.e. Introduced the use of very small electronic circuit called integrated circuits (IC) by combining several transistors together between 3 transistors to make 1 IC. Then, replace each block of four digits with its corresponding hexadecimal digit. chip(IC). The external components of a computer are called peripheral devices which include input and output. Many disk devices, however, do not record data on the top of the top platter or on the bottom of the bottom platter. o Scanner allows you to scan documents, pictures, or graphics and view 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. Computers cannot do any useful work without instructions from software; thus a combination of software and hardware (the computer) is necessary to do any computerized work. There are many reasons for a slow computer, but upgrading the computer's hardware can help speed it up. To convert from hexadecimal to binary, simply look at the chart above and replace each digit in the hexadecimal number with its corresponding four-digit binary number. 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. The purpose is to reduce the time it takes to move the access arms of a disk pack into position. The easy cases to diagnose are those where the monitor or LCD isn't powering up properly, or the PC not powering up. This is the most flexible type of ROM, and is now commonly used for holding BIOS programs. It is the smallest of the three computers. Governments specially use this type of computer for their different Operating systems(OS) acts as an interface between the computer hardware and the computer user and manages the whole computer system. Record the 11. The high level languages commonly used are FORTRAN (FORmula TRANslation), BASIC (Beginner's All-purpose Symbolic Instruction Code), COBOL (COmmon Business Oriented Language). came UNIVAC (universal automatic computers). C. Interrupts; types of interrupt, interrupt priorities, interrupt handler. Removable disk storage units were developed for use on these machines. In most of these cases one deals with Data Base Management Systems (DBMS). consumed a lot of power and generated a lot of heat (overheating). As we have already noted, magnetic tape is used primarily for backup purposes. Many cheaper PC's ship with power supplies I would basically describe as "disposable." Lecture 21 (TBS): computers and handle hundreds of users they are also used in space exploitation.

The term mainframe was mainly used for earliest computers as they were big in A CD-RW allows you to read, write, erase and write again. Put 1 in the 2^3 column, and 0 in 2^4 and 2^5. 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). 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. This product is analogous to a commercial software CD-ROM that you purchase in a store. Computer System Architecture Notes: Computer does not cover memory design in any depth and I will provide detailed A data bus provides a bi-directional path for moving data and instructions between system components. Computer systems are constructed of digital electronics. PROM, but it does require the erasing light. once. category was ENIAC (electronic discrete variable automatic computer) and later 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. In Fig 1.3 you can see the ejector clips (D), using your finger, push these into the down position as shown in Fig 1.3, this allows the memory to be inserted. 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 we divided the number by two, we "took out" one power of two. The notches we have marked as B, are used to align the memory module with the DIMM slot keys C, as shown in Fig 1.3. What happens when, for example, a key on the keyboard is pressed, thus generating an interrupt? Although the user enter data in decimal or character form, it is converted into binary digits and accesses addresses in memory. Explain the characteristics of computers and how they are different from Input unit B. x[r+&YU@lJSvB%d#QTD[/\{g\\S In fact, flash memory is known as a solid state storage device, meaning there are no moving parts --everything is electronic instead of mechanical. character recognition (OCR) software is needed Fuller F., Larson B., Computers: Understanding Technology (Second Edition), Assessment: Examination -70%: Coursework -30%. read the textbook and, preferably, the posted notes before coming to (a) Name the two major components of the Central Processing Unit and briefly describe what each does. But the DVD will undoubtedly gain a place as the successor to the CD ROM and is playing an important role in the blending of computers and entertainment centers. A little glass window is installed in the top of the ROM package, through which you can actually see the chip that holds the memory. 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. Newer technologies such as DDR II and SLDRAM (Synclink DRAM) are emerging. Most computer electronics use voltage levels to indicate their present state. Static RAM does not need to be refreshed, which makes it faster; but it is also more expensive than dynamic RAM. Subtract 8 from 11 to get 3. (a) Vacuum tubes (b) Capacitors (c) Transistors (d) Integrated circuits, Which one of the following types of computers is commonly used in offices A. While information retrieval is faster than from a floppy disk, it is still not as fast as from the hard drive. A disk drive is a machine that allows data to be read from a disk or written on a disk. In addition, the EISA can accommodate a 16-bit ISA card in the first row. 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. The CPU is connected to the main memory by three separate buses. many applications, EAROM has been supplanted by CMOS RAM backed-up by Explain how information is stored in a computer c l oc k , registers Rewriting an EAROM is intended to be an general purpose software, integrated packages and software suites. 10 INPUT A,B 20 LET C=A+B 30 PRINT C 40 END, To read the value of A&B A&B are added and result is stored in C Print the value of C Stop execution.
