They are of advanced technology i. the micro era based on large scale This is significant data insurance. I/O controllers are available which can operate both input and output transfers of bits, e.g. Most 4GLs are used to access databases. (20 minutes presentation + 5 minutes for 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. 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. Thus, we would put a 1 in the 2^6 column, and subtract 64 from 75, giving us 11. Writing and understanding programs in assembly language is easier than that of machine language. A Bus is a set of parallel wires connecting two or more components in a computer. implemented in a single piece of silicon device known as a computer chip. Neumann Architecture Model and The purpose is to reduce the time it takes to move the access arms of a disk pack into position. Bus size means the number of bits that can be transmitted together. with the ISA. P. Box 342-01000 Thika Here we are blurring the line a bit between what "read-only" In such a system a task is broken down and shared among processes for faster execution. A typical sequence of actions when an interrupt occurs would be: The computers can execute a program written using binary digits only. %PDF-1.3 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. Although the user enter data in decimal or character form, it is converted into binary digits Invention of IC revolutionalised electronics and started the error of micro-electronics. 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.

Typically, a CD ROM holds up to 650 MB of information. 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. This places the data in diagonal bands that run across the tape rather than down its length. 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. class. 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. 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). 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). and data so that it will be very fast to retrieve them again. When you store a file on tape, the 125th record cannot be read until the 124 records in front of it are read. This is the most flexible type of ROM, and is now commonly used for holding BIOS programs. 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. 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. AxgyL@0#jE:3tBP20zivoKJ]2w\$wkNIkyDXQwsACvc; hq W j The only way a number can be odd is if it has a 1 in the 2^0 column, because all powers of two greater than 0 are even numbers (2, 4, 8, 16). 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. D=0, so we are done, and the decimal number 163 is equivalent to the binary number 10100011. The disk cartridges look like a floppy disk, but are slightly bigger in all dimensions. Since we already knew how to convert from binary to decimal, we can easily verify our result. is done in terms of numeric representation (Binary Digits) of data and information. It has special keys for Obviously this is much more useful than a regular 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. Central Processing Unit is implemented in a single piece of silicon device known as a computer chip. Commands tell the computer to do something, like save the file. The motherboard's main job is to hold the computer's microprocessor chip and let everything else connect to it. Introduction to Computer and its components Email: [email protected] versions, like the CD-ROM's. To accommodate the increased speed, chip manufacturers have designed and built faster RAM chips. D&T: They are slower and less costly compared to mainframe computers but more powerful, reliable and expensive than micro computers. does not cover memory design in any depth and I will provide detailed Each bit of the register represents a different type of interrupt, and if a bit is set, the state of the current process is saved and the operating system routes control to the appropriate interrupt handler. higher voltages around 12 volts). 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.

I. very low i. (d) Convert the following into binary showing your working: i) 45 ii) 97, (f) What is a computer bus? We can easily see that the number 3= 2+1. WebComputer Organization and Architecture Tutorial provides in-depth knowledge of internal working, structuring, and implementation of a computer system. The process is the same for multiple-bit binary numbers: Column 2^0: 0+1=1. Put 1 in the 2^3 column, and 0 in 2^4 and 2^5. 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. 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. This is sometimes referred to as direct overwriting and can be repeated several thousand times per disc. Let's take a look at how it works. The tubes consumed a lot of power and generated a lot of heat (overheating). The arithmetic/logic unit(ALU) plays two roles. Disk data is quite reliable, especially within a sealed module. Made of flexible Mylar, a diskette can record data as magnetized spots on tracks on its surface. many applications, EAROM has been supplanted by CMOS RAM backed-up by Hard disk capacity for personal computers has soared in recent years; capacities of hundreds of megabytes are common and gigabytes are not unusual. erasability is the EEPROM , which can be erased under software control. These computers used transistors after invention of transistors. The high level languages commonly used are FORTRAN (FORmula TRANslation), BASIC (Beginner's All-purpose Symbolic Instruction Code), COBOL (COmmon Business Oriented Language). Examples operating systems that use command based interface are Ms Dos and Unix. Several disks can be assembled into a disk pack. times per second!

Memory allocation: malloc and Whereas, Organization defines the way the system is structured so that all those catalogued tools can be used properly. analogous to a commercial software CD-ROM that you purchase in a store. Programming and problem SDRAM (Synchronous DRAM) divides RAM into two separate memory banks to increase the processing of the memory requests. If you cannot divide the binary number evenly into blocks of four digits, add zeros to the left side of the number to make it work. DDR SDRAM (Double Data Rate SDRAM) can transfer data twice as fast as SDRAM because it reads data twice during each clock cycle.
