computer fundamentals notes
4. A typical hard disk is built right into your, What is SDRAM (synchronous DRAM)? It is a kind of RAM that can store the data even when there is no power. Computer Fundamentals class 11 Notes Computer Science.CBSE quick revision note for class-11 Mathematics, Physics, Chemistry, Biology and other subject are very helpful to revise the whole syllabus during exam days. [Read more…] about What is VRAM (video ram)? Android is unique because Google is actively developing the platform but giving it away for free to hardware manufacturers and phone carriers who want to use Android on their devices. Memory: It facilitates the remembrance power to computer system. 0 or 1. e) Workstations A terminal or desktop computer in a network. SDRAM introduced in 1969-70. What do you mean by term firmware? From Small scale integrated circuits which had 10 transistors per chip, technology developed to MSI circuits with 100 transistors per chip. It is where programs and data kept for long-term storage or when not in immediate use. Most modern semiconductor volatile memory is either Static RAM or dynamic RAM. 3. SDRAM introduced in 1969-70. Where do you find analog computers in daily life? It is characterized by its slowness and cheapness, relative to the RAM, and by its permanent appearance. Fatal error!? – Definition. It consisted of thousands of tiny rings called cores, made from a magnetic FERRITE material and each threaded onto three fine copper wires: the whole formed a two-dimensional mesh much like a knitted textile. ROMs, PROMs and EPROMs that have data or programs recorded on them are Firmware. For Octal three digit binary & for Hexadecimal four digit binary. Eg. Fifth generation of computer is a symbol of intelligence. Example: DOS. JavaTpoint offers too many high quality services. Dear Aspirant, Today we are covering the study material on Computer Fundamentals, that will help you succeed in the upcoming exam.. Computer: A computer is a truly amazing machine that performs a specified sequence of operations as per the set of instructions (known as programs) given on a set of data (input) to generate desired information (output). That’s why we use it in the variety of electronic types of equipment which require a stable and efficient power supply. Operating system Operating system is a platform between hardware and user which is responsible for the management and coordination of activities and the sharing of the resources of a computer. Definition: A laser printer (also known as Page Printers as they prints the whole page at once) represent a real technological revolution. Types of Application Software. [Read more…] about What is Cycle Time? For example, weather forecasting requires a supercomputer. Intel 80386 processor, Intel 80486 64 bit Microprocessor: It indicates the width of the registers; a special high-speed storage area within the CPU. • USER = Person, who operates computer. It means it can perform a programmed list of instructions and react to new instructions that it is given. about What is Auxiliary memory (secondary storage)? EPIC (Explicitly Parallel Instruction Computing): It is a 64-bit microprocessor instruction set, jointly defined and designed by Hewlett Packard and Intel, that provides up to 128 general and floating point unit registers and uses speculative loading, predication, and explicit parallelism to accomplish its computing tasks. Two types of memory are used by the computer, one for storing data permanently and second for operating. Using these symbols as digits we can express any quantity. 6. [Read more…] about What is Auxiliary memory (secondary storage)? Mapping is important to computer performance, both locally (how long it takes to execute an instruction) and globally (how long it takes to run a set of programs). But if you’re running out of memory-if certain programs won’t run or you can’t create large files-you need some background knowledge before you march down and buy more memory. There are many query language like SQL, Search Engine Query Language (Google, Bing), DMX (Data Mining Language), etc. Booting The process of loading the system files of the operating system from the disk into the computer memory to complete the circuitry requirement of the computer system is called booting. NUMBER SYSTEM: A. Decimal Number System: Decimal Number system composed of 10 numerals or symbols. d) Micro Computer i. USB is host based, mean device must connect to computer while Firewire is peer-to-peer. Bare use of hardware is not easy, so to make it easy software is created. Through EEPROM, an individual byte of data can erase and reprogrammed entirety, not selectively by the electrical voltage. – Definition, Primary memory is also known as main memory or may also refer to “Internal memory.” and primary storage. Types of Application Software. The UV light clears the data on the chip so that it can reprogram. used to work with information or compute. Included features : Explained all the basic details and relevant images with all computer fundamental topics. we can not take control of CPU in between until the current process completes its execution. Another term for multi-user is time sharing. – Definition, about What is Secondary Memory? Nowadays it is also used in other systems. Our Computer fundamentals is designed for beginners and professionals.

As the bulk of data increases with the complexity of systems and multiple process running head to head it leads to most feared complication called Deadlock. SRAM retains its contents as long as the power is connected and is easy to interface to but uses six transistors per bit.
