Once the commands are entered on the prompt a command line interpreter(CLI) identifies and executes the commands. Furthermore, data files, particularly those accessed by several users, are subject to errors introduced by users. iii. links that I will post to other websites. Computer System Architecture Notes: Computer Erasable Programmable ROM (EPROM): An EPROM is a ROM that can be erased and reprogrammed. This is significant data insurance. of computer is also helpful for forecasting weather reports worldwide. Two's column: Dividing 162 by 2 gives 81. These suites offer four or more software products packaged together at a much lower price than buying the packages separately. Secondary storage is necessary because memory, or primary storage, can be used only temporarily. 17. Operating systems(OS) acts as an interface between the computer hardware and the computer user and manages the whole computer system. Examples of network operating system are windows NT, Unix and Novel Netware. The clock speed, therefore, is one of the factors which will influence the speed at which instructions are executed; a 600MHZ processor will in general operate faster than a 500MHz processor. Hard disk for mainframes and minicomputers may be as large as 14 inches in diameter. Perhaps more important than capacity, however, is the convenience of speed. Mainframe computers They are usually called personal computers since they are designed to be used by individuals. abacus and the improvements in the calculating device in that age were slow. 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 lecture -- the notes posted here provide, in some cases, more To overcome the performance limitations of SDRAM, two competing technologies have been developed. Final result: 11001. The sector method is used for diskettes as well as disk packs. As in other magnetic media, data is stored as extremely small magnetic spots.

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. Consider the addition of decimal numbers: We begin by adding 3+8=11. software program. Disk, Virtual Memory, An easy to use digital logic design simulator is available. A set of programs associated with the operation of a computer. the most flexible type of ROM, and is now commonly used for holding BIOS Bus size means the number of bits that can be transmitted together. The small circuitry that resulted improved the processing speed i.e. Introduction to Computer and its components Graphical user interface has some disadvantages such as. A. 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. They used magnetic tape. college. Hard disks use magnetism, while computer memory uses electric charges stored in tiny capacitors to indicate "on" or "off.". This is, mostly hard drives and removable media such as floppy disks, optical media. Examples operating systems that use command based interface are Ms Dos and Unix. 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). keyboard controller or as output controller, e.g. (a) Vacuum tubes (b) Capacitors (c) Transistors (d) Integrated circuits, Which one of the following types of computers is commonly used in offices Region one is USA and Canada, while Europe and Asia is region two. Hardware and software chapters. Everything that runs the computer or enhances its performance is either part of the motherboard or plugs into it via a slot or port. The 17 GB disk holds 200 hours top quality music recording. Explain the different types of computers categorized based on size, price 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. This is inflexible and so regular ROMs are only used generally for A single bit alone cannot represent a number, letters or special characters, to represent information; bits are combined into groups of eight. Video failure can also be due to motherboard failure or to external interference, when it comes to poor image quality. This is mostly hard drives and removable media such as floppy disks, optical media (CD ROM) etc. The 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. In such a system a task is broken down and shared among processes times per second! It is usually necessary to scan some (but not all) of the preceding data. data .They are physically very large in size with very high capacity of main High level language permits the user to use understandable codes using the language structure. Obviously this is much more useful than a regular PROM, but it does require the erasing light. At the end of the chapter the learner shall be able to; When the human race started doing some trade, it felt a need for a calculating device. 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.

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." Software: Categories of software, System software, applications software, Cas a model of computation Digital logic as a model of computation Programmers view of how a computer system works HW designers view of Since 81 is odd, a[1]=1. They made use of vacuum tubes to store and process information. Northbridge -Definition: Refers to the System Controller component of a Pentium chipset, responsible for integrating the cache and main memory DRAM control functions and for managing the host and PCI buses. Reduce the bandwidth required of the large memory Processor Memory A concept of using several small disks that work together as a unit is called a redundant array of inexpensive disks, or simply RAID. implementations for the various parts of a computer, focusing largely on 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. temperature, speed etc. The disk cartridges look like a floppy disk, but are slightly bigger in all dimensions. 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.

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. IV. This is similar to the way a CD-ROM recorder and cost goals. A little glass window is installed in the top of the 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. They are 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. All 4GLs are designed to reduce programming effort, the time it takes to develop software, and the cost of software development. Hard disks come in a variety of sizes. A data bus provides a bi-directional path for moving data and instructions between system components. Winchester disk assemblies are put together in clean rooms so even microscopic dust particles do not get on the disk surface. 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. 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. A motherboard by itself is useless, but a computer has to have one to operate. The motherboard's main job is to hold the computer's microprocessor chip and let everything else connect to it. The data layer is only half as thick as in the CD-ROM. Typically, a CD ROM holds up to 650 MB of information. They are mainly used for presentations. 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. However, the amount of time it takes to access a record is dependent to some extent on the mechanical process involved. Flash memory is a type of EEPROM chip, which stands for Electronically Erasable Programmable Read Only Memory. This is inflexible and so regular ROMs are only used generally for programs that are static (not changing often) and mass-produced. The diagram above shows how the units interact with each other in the processing of data. increased. (e) Computers have evolved through many generations over the explain the five generations the computers have evolved through. 5GL or fifth-generation language is programming that uses a visual or graphical development interface to create source language that is usually compiled with a 3GL or 4GL language compiler. Thus, the answer is 71. The Basic Input/Output System (BIOS) chip controls the most basic functions of the computer and performs a self-test every time you turn it on. Making this algorithm a bit more formal gives us: This algorithm is a bit awkward.

This is useful for companies that make their own ROMs from software they write, because when they change their code they can create new PROMs without requiring expensive equipment. This is the most flexible type of ROM, and is now commonly used for holding BIOS programs. typing, recording keeping, production of financial statements, drawing, and statistics. 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.

It is the main part of a computer system like the brain of a human being. The tubes GCD210267, Watts and Zimmerman (1990) Positive Accounting Theory A Ten Year Perspective The Accounting Review, Subhan Group - Research paper based on calculation of faults. contains materials that are frequently examined. In 1998 Macintosh introduced its new computer, the IMAC, without a floppy disk drive. To appreciate this, suppose you had an empty disk pack on which you wished to record data. peripherals can be attached to them. For example, a transistor with five volts would be considered "on", while a transistor with no voltage would be considered "off." Furthermore, data security is improved because if a disk fails, the disk system can reconstruct data on an extra disk; thus, computer operations can continue uninterrupted. software Here are the digits used in hexadecimal and their equivalents in binary and decimal: Let's count in hexadecimal. It may also be defined as the science and art of selecting and interconnecting 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. 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. ); it can be written to, but only Decode translate the program instruction into commands that the 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. This process continues until we have a remainder of 0. huge in size and occupy a room. State and explain any five characteristics of storage. 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. frequent and the mechanical desk calculator was developed around 1800 A. To converty from binary to hexadecimal, reverse the procedure and break the binary number into blocks of four digits. These computers were mostly This kind drive. the number 193 is really {(1*10^2)+(9*10^1)+(3*10^0)}. using special equipment (a PROM programmer. to read the textbook and, preferably, the posted notes before coming to class.

It can process trillions of instructions in seconds. classified and known as super computer. Topics may include: instruction set design; processor micro-architecture and Course Info Instructors to be reprogrammed again. The CPU is connected to the main memory by three separate buses. In most of the Hollywoods movies it is used for animation purposes. 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). Data are stored in a small indentation in a spiral track, just like in the CD. 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. The input and output devices are discussed in details in chapter 2 of the module. This translates into putting a "1" in the 2^1 column and a "1" in the 2^0 column, to get "11". Let's try the number D=55. You can also use software to edit the items you Data can also be destroyed if a read/write head encounters even minuscule foreign matter on the disk surface. I don't mean that hard drives last longer than memory modules or video cards in the pure MTBF (Mean Time Between Failure) sense, I mean they are rarely at fault when you're called in to repair a PC. 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. 2022, Assignment 1. Zip disks are a great way to store large files and software programs. Following this, the changes were frequent and the mechanical desk calculator was developed around 1800 A.D. While information retrieval is faster than from a floppy disk, it is still not as fast as from the hard drive. They are used to enter information and issue commands to the computer. The processor contains the control unit and the arithmetic/logic unit(ALU) and the system clock. They can be divided into; Are programs for user to do their jobs e.g. Take the number 163. Central Processing Unit is 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. Explain the different hardware units of a computer system such as input, Video Failure Troubleshooting 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. It 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. 18-213 18-240. 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. The arithmetic/logic unit(ALU) plays two roles. This method produces high density and faster access to data. requiring expensive equipment. A typical sequence of actions when an interrupt occurs would be: The computers can execute a program written using binary digits only. Applications software packages sometimes include a dozen diskettes or more; all these could fit on one optical disk with plenty of room to spare.

The speed of these machines was described in milliseconds (1/1000 of a second), Second generation computers (1957-1967) Explain the fundamental difference between computer hardware and Electrically Erasable Programmable ROM (EEPROM): The next level of once. You should also refer to the lecture notes available from the textbook website. Most mainframe computers have 32-bit words. This opens the possibility to write data in two layers. Programming and problem In fact, programming a PROM is also called burning, just like burning a CD-R, and it is comparable in terms of its flexibility. Saving and retrieving information from a floppy disk is slower than on a hard drive. Visual programming allows you to easily envision object-oriented programming class hierarchies and drag icons to assemble program components. and data so that it will be very fast to retrieve them again. In decimal form, 1+1=2. Punched cards, paper tape, and magnetic tape are examples of sequential-access storage media. Following this, the changes were Color laser printers are still fairly expensive. Each column in hexadecimal is worth 16 times the column before, while each column in binary is worth 2 times the column before. Pages 4-. Binary addition works on the same principle, but the numerals are different. Governments specially use this type of computer for their different calculations and heavy jobs. The DVD drives come in 2X, 4X, etc. They are used for complex tasks requiring a lot of For example, 8F in hexadecimal is 10001111 in binary, since 8=1000 and F=1111.

This is similar to the way a CD-ROM recorder works by letting you "burn" programs onto blanks once and then letting you read from them many times. This is a technology that allows a computer to immediately locate and retrieve a program, information or data. 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. Chapter 1- Fundamentals of Computer Design. Put 1 in the 2^3 column, and 0 in 2^4 and 2^5. It is also easy to see that multiplying and dividing by 2 shifts everything by one column: two in binary is 10, or (1*2^1). Also it will be very difficult for a person to understand a machine language program written by another person. 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. D. Hard Drive Failure Troubleshooting, V. Input and output devices and interrupts. 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). the maim memory, and works by storing the most frequently or recently used instructions Ch19 - Chapter 19 solution for Intermediate Accounting by Donald E.

First machine in this A disk drive is a machine that allows data to be read from a disk or written on a disk. For example, if the data bus is 8 bits wide, and each instruction is 16 bits long, then the processor must access the main memory twice during each instruction cycle. B. The set of instructions is often called a program or, if the set is particularly large and complex, a system. Central processing unit (CPU) or processor 2. Analog Magnetic disks and drums are examples of direct-access storage media. The record storage rooms would have to be enormous. These patterns of "on" and "off" stored inside the computer are used to encode numbers using the binary number system. refer to the This product is analogous to a commercial software CD-ROM that you purchase in a store. An input device lets you communicate with a computer. 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. @@TTA When the processor wishes to read a word (say 8, 16, 32 bits) of data from memory, it first puts the address of the desired word of the address bus. Electrically Alterable Read-Only Memory(EAROMs) can be modified a bit at a 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. erased and reprogrammed.
