All the tracks thus encountered, in the same position on each disk surface, comprise a cylinder. They are mainly used for presentations. In most of the Hollywoods movies it is used for animation purposes. A disk pack is mounted on a disk drive that is a separate unit connected to the computer. Particularly step 3, "filling in the zeros." The diagram above shows how the units interact with each other in the processing of data. It is the smallest of the three computers. 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. The CPU of a microcomputer is called a microprocessor. However, the amount of time it takes to access a record is dependent to some extent on the mechanical process involved. within a computing system such as: Objectives Their input /output capabilities were usually limited to the keyboard and or punched card input and printer and or punched cart output. In short a COMPILER is: the translator of the source code into computer language. The DVD drives come in 2X, 4X, etc. When you hear reference to a "flash BIOS" or doing a BIOS upgrade by "flashing", this refers to reprogramming the BIOS EEPROM with a special software program. For example, "3" in binary cannot be put into one column. With IC you can house thousands of transistors in one IC. o Microphone Used to put sound into a computer. taken by a digital camera can be used directly by a computer We can start at the right, rather than the left. 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. Many new PCs come with Zip drives built in addition to floppy drives. The first motherboards held very few actual components. State and explain any five characteristics of storage. To overcome the performance limitations of SDRAM, two competing technologies have been developed. (b) List four of the conditions an ALU tests for. (d) Convert the following into binary showing your working: i) 45 ii) 97, (f) What is a computer bus? 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. The real time clock chip is a battery-operated chip that maintains basic settings and the system time. Here we are blurring the line a bit between what "read-only" The next change came after about 1600 years. The lecture notes posted are not the 0s and 1s with 0 representing an OFF state and 1 representing an ON state. The IBM 360 is an example of third generation computers.

Explain the different types of computers categorized based on size, price The stored bits are usually retrieved from computers memory for manipulation by the processor. A motherboard by itself is useless, but a computer has to have one to operate. 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. D=0, so we are done, and the decimal number 163 is equivalent to the binary number 10100011. If we put the 1 in the 2^0 column, we have 162 left, and have to decide how to translate the remaining digits. Performance and Code o Digital Camera Used to take electronic pictures of an object. implementations for the various parts of a computer, focusing largely on of Maryland. 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. o Scanner allows you to scan documents, pictures, or graphics and view A large number of peripherals can be attached to them.

This places the data in diagonal bands that run across the tape rather than down its length. Other controllers operate in one direction only, either as an input controller, e.g. 2kb and speed of processing was also very low. Temporary Result: 001; Carry: 1, Column 2^3: 1+1=10. Computer System Architecture Notes: Computer The system unit is the unit that houses the processing unit (processor), memory, the input output controllers and the buses. Magnetic tape looks like the tape used in music cassettes plastic tape with a magnetic coating. The high level languages commonly used are FORTRAN (FORmula TRANslation), BASIC (Beginner's All-purpose Symbolic Instruction Code), COBOL (COmmon Business Oriented Language). 6.823 is a study of the evolution of computer architecture and the factors influencing the Since Assembly language is machine dependent each type of computer has its own assembler. infrequent operation - most of the time the memory is used as a ROM. WebCS 135: Computer Architecture I Fall 2010 Lecture Notes. i. We saved magnetic tape storage for last because it has taken a subordinate role in storage technology. DVD disks are read by a laser beam of shorter wave-length than used by the CD ROM drives. A keyboard, mouse, scanner, digital camera, Microcomputers can be a desktop, laptop, notebooks, or even palmtop. The number 81 in binary would also have a 1 in the 2^0 column. Here is a link to some online notes that I found to be well It Everything that runs the computer or enhances its performance is either part of the motherboard or plugs into it via a slot or port. Obviously this is much more useful than a regular These computers were mostly computational machines. This kind This type of programs is called machine language programs and the programming language is called machine code. generation saw the introduction of more complex ALU and CPU, the use of high A typical data bus consists of 8, 16, or separate lines. o Voice input device- A computer I/O device in which vocal commands Continuing the "CD" analogy, this technology is analogous to a reusable CD-RW.

Computer architecture or digital computer organization is the conceptual design and fundamental operational structure of a computer system. All the processor activities, such as fetching an instruction, reading data into the memory register etc. Diskettes became popular along with the personal computer. computer can process The Making this algorithm a bit more formal gives us: This algorithm is a bit awkward. ntz0_u.E5Yo!& Then, replace each block of four digits with its corresponding hexadecimal digit. 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. The size of a hard drive is usually expressed in terms of megabytes and The data is recorded on the tracks that can be accessed by one positioning of the access arms-that is, on one cylinder. EISA is the second most commonly used interface for disk drives. A different ISR is provided for each different source of interrupt. 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. For example, a transistor with five volts would be considered "on", while a transistor with no voltage would be considered "off." The size of a hard drive is usually expressed in terms of megabytes and gigabytes. o Speakers Used to output sound Pages 4-. Subtract 8 from 11 to get 3. Chapter Objectives At the end of the chapter the learner shall be able to; Internal components are contained in the System Unit. They are more susceptible to physical damage and viruses than the hard Sometimes you can spot a blown capacitor on a motherboard, but it's not a common problem. 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. increased.
