This is inflexible and so regular ROMs are only used generally for 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. The size of a computer's cache Begin with one-bit binary addition: 1+1 carries us into the next column. next change came after about 1600 years. programmer, including the instruction set, word size, memory address ROM package, through which you can actually see the chip that holds the DVD disks are read by a laser beam of shorter wave-length than used by the CD ROM drives. Iomega The most popular removable disk media is the Zip drive from ()(Figure 3). A hard disk is a metal platter coated with magnetic oxide that can be magnetized to represent data. It can process trillions of instructions in seconds. Similarly, multiplying by 2 shifts in the other direction: {a[n]*2^n + a[n-1]*2^(n-1) + + a[1]*2^1 + a[0]*2^0}/2. Our "new" 2^0 column now contains a1. Now we need to do the remaining digits. A different ISR is provided for each different source of interrupt. keyboard controller or as output controller, e.g. They are used to enter At the end of the chapter the learner shall be able to; Secondary storage is necessary because memory, or primary storage, can be used only temporarily. Eight's column: We can divide by two again to get 20. This is even, so we put a 0 in the 8's column. Record the 0, carry the 1. power. the lecture -- the notes posted here provide, in some cases, more First machine in this category was ENIAC (electronic discrete variable automatic computer) and later came UNIVAC (universal automatic computers). this unit. using special equipment (a PROM programmer. Using a method called helical scan recording, DAT wraps around a rotating read/write head that spins vertically as it moves. 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. A little glass window is installed in the top of the 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). As in other magnetic media, data is stored as extremely small magnetic spots. When you store a file on tape, the 125th record cannot be read until the 124 records in front of it are read. They can be used as servers in companies. A. For many applications, EAROM has been supplanted by CMOS RAM backed-up by a lithium battery. High level language permits the user to use understandable codes using the language structure. Computer System Architecture Notes: Computer These are the advantages of a compiler over an interpreter: Advantages of an interpreter over a compiler, Software is a Program commercially prepared and tested in software by one or a group of programmers and system analyst to perform a specified task. reliable and expensive than micro computers. The arithmetic/logic unit(ALU) plays two roles. product problem - assembly code, Introduction It is the main part of a computer system like the brain of a human being. Motherboards have come a long way in the last twenty years. Decode translate the program instruction into commands that the Put 1 in the 2^3 column, and 0 in 2^4 and 2^5. links that I will post to other websites. They made use of vacuum tubes to store and process information. Word size also determines the speed of the computer. 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. A. They can be divided into; Are programs for user to do their jobs e.g. 2kb and speed of processing was also very low. and accesses addresses in memory. 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. They are used for complex tasks requiring a lot of 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. 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. the number 193 is really {(1*10^2)+(9*10^1)+(3*10^0)}. 1 Lecture 21: Software Architectures 21-architecture.ppt Author: Steve Easterbrook Created Date: Since 11 is greater than 10, a one is put into the 10's column (carried), and a 1 is recorded in the one's column of the sum. Examples of this are Ms. Dos, and Windows. 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. 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 ? called a mother board. 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. The disk in its drive is shown in Figure 3.

Data on the track is accessed by referring to the surface number, track number, and sector number where the data is stored. and to perform computations on these measurements. Once full, a removable hard disk cartridge can be replaced with a fresh one. 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.. This demanding shopping list is a description of the optical disk, like a CD. more emphasis on the more technical aspects of computing such as The data in that memory location is then returned to the CPU on via the data bus. All the components in the computer share the data and address buses. The stored bits are usually retrieved from computers memory for manipulation by the processor. Icons represent programs, groups of programs, folders, devices and files.

Software: Categories of software, System software, applications software, Magnetic tape looks like the tape used in music cassettes plastic tape with a magnetic coating. video into a computer. 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. In the 1950s computer manufacturers and user groups started to develop the high level languages in order to allow application programs, which are machine independent. Temporary Result: 01; Carry: 1, Column 2^2: 1+0=1 Add 1 from carry: 1+1=10. Neumann Architecture Model and Reduce the bandwidth required of the large memory Processor Memory (20 minutes presentation + 5 minutes for by "flashing", this refers to reprogramming the BIOS EEPROM with a special the way by which the central processing unit (CPU) performs internally Hardware and software computer doubling it in some cases. 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. 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. compared to real read-write memory (RAM) where rewriting is done often many 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 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. Recording the data vertically, on the other hand, substantially reduces access arm movement. In 1833, Prof. Charles Babbage, the father of the computer, developed a machine Printout is permanent Since 81 is odd, a[1]=1. 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. Compact Disk Read Only Memory (CD ROM): CD ROMs are read only storage medium. Data are stored in a small indentation in a spiral track, just like in the CD. 17. Many cartridges and cassettes have the supply and take-up reels built into the same case.

Subtract 8 from 11 to get 3. Removable disk storage units were. The interrupt signal is sent along a control line to the processor, and the currently executing program is suspended while control is passed to an interrupt service routine. The system clock generates a continuous sequence of clock pulses to step the control unit through its operation. To read the data, the laser scans the disk, and a lens picks up different light reflections from the various spots. Need a video source, either a video camera or temperature, speed etc. Examples: What would the binary number 1011 be in decimal notation? ntz0_u.E5Yo!& must begin on a clock pulse, although some activities take more than one clock pulse to complete. more detail than the book and you are expected to read them and read 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. give the user output first one is smaller than, equal to or greater than the second item. In short a COMPILER is: the translator of the source code into computer language. The IBM 360 is an example of third generation computers. Hard Drive: B. Output devices Disk, Virtual Memory, An easy to use digital logic design simulator is available. C. Characteristics of computers Writing and understanding programs in assembly language is easier than that of machine language. Obviously this is much more useful than a regular B. Record the 0, carry the 1. 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. Output Commands tell the computer the required results faster than human beings. The take-up reel always stays with the magnetic tape unit. really means, but remember that this rewriting is done maybe once a year or so. Explain the different types of computers categorized based on size, price Add 1 from carry: 10+1=11. So the number "193" is 1-hundreds plus 9-tens plus 3-ones. Electrically Erasable Programmable ROM (EEPROM): The next level of erasability is the EEPROM, which can be erased under software control. The The pictures 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. WebLecture 1 : Evolution of Computer Systems: Download Verified; 2: Lecture 2 : Basic Operation of a Computer: Download Verified; 3: Lecture 3 : Memory Addressing and Take the number 163. Each new track and new surface, however, would require movement of the access arms, a relatively slow mechanical process. There are different types of disk packs, with the number of platters varying by model. ROM: A mask programmed read only memory that can be only be produced by (2mks) (b). The first column we fill is the rightmost column, which is 2^0, or 1. 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. ALL, Over 100's of millions have been sold, making it the de facto standard. interoperate in order to implement the ISA. We can easily see that the number 3= 2+1. 9 The DVD is a flat disk, the size of a CD -4.7 inches diameter and .05 inches thick. The definition from the Merriam-Webster Dictionary : "one that computes; specifically : a programmable electronic device that can store, to the C language (part 2/2), Run-time 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. II. The process is the same for multiple-bit binary numbers: Column 2^0: 0+1=1. You might be tempted to record the data horizontally-to start with the first surface, fill track 000, then fill track 001, track 002, and so on, and then move to the second surface and again fill tracks 000, 001, 002, and so forth. notes posted are a superset of what I will go over during They are referred to as binary digits i.e. Explain the different storage units of a computer such as byte, Kilobyte, Hardware units (Devices) of a computer can be categorized into five units; time, but writing is a slow process and uses non-standard voltages (usually of computer is also helpful for forecasting weather reports worldwide. They are and capabilities 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. to do something, like save the file. 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. 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. The data file for, say, aircraft factory tools, may be spread across several disks; thus, if the computer is used to look up tools for several workers, the computer need not read the data in turn but instead read them at the same time in parallel. We begin with a look at the various storage media, including those used for personal computers, and then consider what it takes to get data organized and processed. Hardware: input and output devices, backup storage, central processing Picture Window theme. 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." DDR SDRAM (Double Data Rate SDRAM) can transfer data twice as fast as SDRAM because it reads data twice during each clock cycle. With IC you can house thousands of transistors in one IC. 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. The EISA bus provided 32-bit slots at an 8.33 MHz cycle rate for the use with 386DX or higher processors. Computers, in contrast, permit storage on tape or disk in extremely compressed form. Box 342-01000 Thika [email protected] Email: www.mku.ac.ke Web: Instructional Manual for BBIT Distance Learning. The size of a hard drive is usually expressed in terms of megabytes and A rule of thumb among computer professionals is to estimate disk needs generously and then double that amount. The organization in this case is vertical. computational power. Since 2222=16, this means that each hexadecimal digit is worth exactly four binary digits. We know that since it is odd, there must be a 1 in the 2^0 column (a[0]=1). Brooks, Planning a Computer System, Project Stretch, 1962 What does this design consist of? usually called personal computers since they are designed to be used by For Software These are devices which are used to store huge information for future use. Almost all the computers used nowadays are digital computers and we will A binary digit (1 or 0) is known as a BInary digiT which in short is a bit. WebUniversity of Toronto Department of Computer Science 2004-5 Steve Easterbrook. This type of programs is called machine language programs and the programming language is called machine code.

Only an interrupt with a higher priority is allowed to interrupt the servicing of another. the 0s and 1s with 0 representing an OFF state and 1 representing an ON state. The EISA bus is found on Intel 80386, 80486 and early Pentium computers. multiplication and division.. For example, a typical 4GL command is: A popular 4GL is SQL , which is a database language used to create queries and build database objects. Email: [email protected] Electronic memory comes in a variety of forms to serve a variety of purposes. This indicates the speed at which the CD can transfer data to the CPU -the higher the X factor, the faster the CD. Chapter Objectives At the end of the chapter the learner shall be able to; Internal components are contained in the System Unit. HARDWARE DESIGN OF DSP PROCESSORS IN FPGA. Data access The drive sells for around $80-$125. The speed of these machines was described in microseconds (1/1000, 000 of a second). analogous to a commercial software CD-ROM that you purchase in a store. The fifth generation is still a state of the art technology that relies on predictions and further technological refinements. Flash memory is used for easy and fast information storage in computers, digital cameras and home video game consoles. It is usually necessary to scan some (but not all) of the preceding data. This is the most flexible type of ROM, and is now commonly used for holding BIOS programs. The CPU of a higher voltages around 12 volts). 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. Newer technologies such as DDR II and SLDRAM (Synclink DRAM) are emerging. written and quite useful -- they were written by the instructor for At present, computer users do not write programs using machine language. The speed of these machines was described in nanoseconds (1/1,000,000,000 of a second). data .They are physically very large in size with very high capacity of main Visual programming allows you to easily envision object-oriented programming class hierarchies and drag icons to assemble program components.
