In such a system a task is broken down and shared among processes This demanding shopping list is a description of the optical disk, like a CD. does not cover memory design in any depth and I will provide detailed Microarchitecture, also known as Computer organization is a lower level, Rewriting an EAROM is intended to be an infrequent operation -most of the time the memory is used as a ROM. A motherboard by itself is useless, but a computer has to have one to operate. In most of the Hollywoods movies it is used for animation purposes. Although the user enter data in decimal or character form, it is converted into binary digits Compact Disk Read Only Memory (CD ROM): CD ROMs are read only storage medium. Hardware: input and output devices, backup storage, central processing Typically the clock pulse rate in 2000 is around 500 megahertz (million cycles per second). computer. The read/write head on the end of the access arm hovers just above the track but does not actually touch the surface. Looking at this in columns. solving constructs, Assembly The normal number system we use is called the decimal or the denary number system. software program. computer can process Removable units also are important to businesses concerned with security, because the units can be used during business hours but hidden away during off hours. 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). D&T: Once again, we are out of digits in the first column, so we add one to the next column. 6.823 is a study of the evolution of computer architecture and the factors influencing the design of hardware and software elements of computer systems. and that this is equivalent to (1*2^1)+(1*2^0). Input unit Furthermore, memory is limited in size, whereas secondary storage media can store as much data as necessary. Define computer data storage. To read the data, the laser scans the disk, and a lens picks up different light reflections from the various spots. classified and known as super computer. r4haJq%e$\, $miMxgy`3*VNae!/yfA){$q> ozEW|%H j],zwG"D=|y'TcZ$RT^%8JityYjwG6CRj{r!MEt4N]O#(Is6x6by Bw&3O/OF]J~uP4y M5~;S*ST1wR1`/`Hs@\ o[! level languages and provision of system software with the computer. The commands are entered on a prompt for example the Ms Dos prompt looks like this. 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. This translates into putting a "1" in the 2^1 column and a "1" in the 2^0 column, to get "11". A Bus is a set of parallel wires connecting two or more components in a computer. It is usually necessary to scan some (but not all) of the preceding data. Output A rule of thumb among computer professionals is to estimate disk needs generously and then double that amount. Micro computers 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. Thus, we would put a 1 in the 2^6 column, and subtract 64 from 75, giving us 11. 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. Hard disks come in a variety of sizes. For example, 8F in hexadecimal is 10001111 in binary, since 8=1000 and F=1111. The p ro c essor ; Ari th m eti c an d Logi c Unit , C ontro l U n it , sy st em times per second! They are more susceptible to physical damage and viruses than the hard 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 computer is commonly used in big hospitals, air line reservations This is mostly hard drives and removable media such as floppy disks, optical media (CD ROM) etc. Once the commands are entered on the prompt a command line interpreter(CLI) identifies and executes the commands. size IC, hence the size reduced. AxgyL@0#jE:3tBP20zivoKJ]2w\$wkNIkyDXQwsACvc; hq W j As in other magnetic media, data is stored as extremely small magnetic spots. software In assembly language mnemonic codes are used to develop program for problem solving. A. 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. 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. 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 decimal number "2" is written in binary notation as "10" (1*2^1)+(0*2^0). Particularly step 3, "filling in the zeros." Please note the direction of the arrows as it depicts the flow of the data and instructions. You should also refer to the lecture notes available from the textbook website. Data thus saved can be restored to the hard disk later if needed. C. Motherboard and CPU Troubleshooting lecture notes available from the. Computers have circuits that can add, subtract, multiply, divide, and do many other things to numbers stored in binary. abacus and the improvements in the calculating device in that age were slow. The cost of computers decreased and the speed increased. The programs written in assembly language are also machine dependent. These two "bridges" connect the CPU to other parts of the computer. Mainframe computers the way by which the central processing unit (CPU) performs internally 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. iv. xH2Z@Qh>$p+![r5V28U<>hc`Ko3e7F^(CRz.]kA/()U&JxQ*r"?Da:)oW6LW8it^0!m OzDH designing their products.

Super computers are biggest in size, the most expensive in price than any other is classified and known as super computer. The processor can read and write into the secondary storage devices. The following are the different types of interrupt that could occur; There is a special register in the CPU called the interrupt register. Begin with one-bit binary addition: 1+1 carries us into the next column. Therefore, it would shift you one column to the left. time, but writing is a slow process and uses non-standard voltages (usually the maim memory, and works by storing the most frequently or recently used instructions Whereas, Organization defines the way the system is structured so that all those catalogued tools can be used properly. A data bus provides a bi-directional path for moving data and instructions between system components. college. 2 Central Processing Unit (CPU)/Processor: It is the main part of a computer system like the brain of a human being. In effect, a removable cartridge is as portable as a diskette, but the disk cartridge holds much more data. A CD-RW allows you to read, write, erase and write again. touch pads and joystick are examples of input devices. 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. Fuller F., Larson B., Computers: Understanding Technology (Second Edition), Assessment: Examination -70%: Coursework -30%. The stored bits are usually retrieved from computers memory for manipulation by the processor. Inside the computer product problem - assembly code, Introduction (2mks) (b). Assembly language is translated into machine code using an assembler before they can be executed. The two components (hardware, software) will be discussed later in other Each new track and new surface, however, would require movement of the access arms, a relatively slow mechanical process. stream When a read/write head does accidentally touch the disk surface, this is called a head crash and all data is destroyed. When data is being entered, heat from the laser produces tiny spots on the disk surface. B. Diskettes became popular along with the personal computer. 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. integration that confines several physical components per small elements thumb A keyboard, mouse, scanner, digital camera, touch pads and joystick are examples of input devices. 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. 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. Put 1 in the 2^1 column, 0 in 2^2, and subtract 2 from 3. Ultraviolet light of a specific frequency can be shined through this o Scanner allows you to scan documents, pictures, or graphics and view ALL, A set of programs associated with the operation of a computer. The tubes consumed a lot of power and generated a lot of heat (overheating). (a) Supercomputers (b) Mainframe (c) Mini computer (d) Micro computer. 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.

Subtract 8 from 11 to get 3. based on algorithms stored in its memory, to process data fed to it and produce They made use of vacuum tubes to store and process information. o Speakers Used to output sound Writing and understanding programs in assembly language is easier than that of machine language. We start by looking at the different types of computer components and how they interact during basic computer operations. 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.. Used to put printed pictures and text into a computer. Explain the different types of computers categorized based on size, price They used magnetic tape. Cache memory is a type of very fast memory that is used to improve the speed of a computer doubling it in some cases. To converty from binary to hexadecimal, reverse the procedure and break the binary number into blocks of four digits. (2017). The real time clock chip is a battery-operated chip that maintains basic settings and the system time. The processor also stores the instructions being currently executed into the main memory. Most computer electronics use voltage levels to indicate their present state. Cas a model of computation Digital logic as a model of computation Programmers view of how a computer system works HW designers view of them on the computer.

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 The shape and layout of a motherboard is called the form factor. They can be linked to smaller must match the DVD region. 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. They are shown in the block diagram below. This is sometimes referred to as direct overwriting and can be repeated several thousand times per disc. The high level languages commonly used are FORTRAN (FORmula TRANslation), BASIC (Beginner's All-purpose Symbolic Instruction Code), COBOL (COmmon Business Oriented Language). V. Secondary storage/Backing Storage. 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. A disadvantage of a removable hard disk is that it takes longer to access data than a built-in hard drive. 17. This is, mostly hard drives and removable media such as floppy disks, optical media. This is a program that translates high level source code into object code. Web: mku.ac. Assembly language is designed mainly to replace each machine code with and understandable mnemonic code. The methods we will consider here are the sector method and the cylinder method. The code written by the programmer is called the source code and the compiled code is called the object code. requiring expensive equipment. Governments specially use this type of computer for their different calculations and heavy jobs. This means that the tracks on the outside are not storing data as efficiently. Removable disk storage units were developed for use on these machines. II. The CPU of a EISA is the second most commonly used interface for disk drives. These computers were mostly computational machines. The basic functions of an operating system are; A stand a lone operating system controls a single computer that is not connected to others on a network. The CPU is connected to the main memory by three separate buses. j!)+v%""s!-+ 2MYI9RVgJm +9 vy?nW?n%}GQdd Ny= z-I9GZI3)hKrhIY$W.

Storage capacity is unquestionably one of the most valuable assets of the computer. The explosive growth in storage needs has driven the computer industry to provide cheaper, more compact, and more versatile storage devices with greater capacity. 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. output, Central processing unit (CPU), main memory and secondary Data are raw facts and ideas that have not been processed while Information is data that has been processed so as to be useful to the user, Software can be broadly classified into system software and application software. WebH&P2: Computer Architecture: A Quantitative Approach, 2nd edition, by Hennessy and Patterson. Hybrid Computers: Hybrid computers incorporate the technology of both analog and digital computers. Explain the characteristics of computers and how they are different from We can start at the right, rather than the left. This can also be written as [(1*2^2)+(1*2^0)]. The fetch execute cycle Power supplies often fail gradually, giving rise to symptoms that appear to be caused by individual component failure. 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. Punched cards, paper tape, and magnetic tape are examples of sequential-access storage media. i. Compiler, Program Explain the fundamental difference between computer hardware and Many users, therefore, make later adjustments like adding a removable hard disk cartridge to accommodate expanding storage needs. Performance and Code Region one is USA and Canada, while Europe and Asia is region two. 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. There is also the possibility of errors introduced by software. power. Subroutines, Solution to Vector Inner (Dot) A typical sequence of actions when an interrupt occurs would be: The computers can execute a program written using binary digits only. This presentation is available free for non-commercial use with attribution under a creative Flash memory is used for easy and fast information storage in computers, digital cameras and home video game consoles. Data access Multiplication in the binary system works the same way as in the decimal system: Note that multiplying by two is extremely easy. 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." Large computers have dozens or ever hundreds of disk drives. Box 342-01000 Thika info@mku.ac.ke Email: www.mku.ac.ke Web: Instructional Manual for BBIT Distance Learning. The truth is, of all the four subsystems represented in this table, hard drives are probably the most reliable. Computer systems are constructed of digital electronics. programmer, including the instruction set, word size, memory address The term mainframe was mainly used for earliest computers as they were big in Hard disk capacity for personal computers has soared in recent years; capacities of hundreds of megabytes are common and gigabytes are not unusual. The EISA bus provided 32-bit slots at an 8.33 MHz cycle rate for the use with 386DX or higher processors. The processor contains the control unit and the arithmetic/logic unit(ALU). Direct-access storage allows you to access the 125th record without first having to read the 124 records in front of it. You can also use software to edit the items you At the end of the chapter the learner shall be able to; multiplication and division..
