The Different Types of Memory Devices This technical report will look at various different memory devices and how they are implemented in a standard computer system. Internal memory devices such as ROM, PROM, RAM, SRAM, DRAM, SIMM and DIMM will be looked at in order to give a clear idea of how each one operates, and external devices such as memory sticks will also be touched upon. Each of these devices uses different types of memory in different ways. Over the course of this report, each
microprocessor is one of the main essentials to review before selecting your computer. The faster the microprocessor, the faster your data will process, when navigating through the software. Memory There are four types of memory. These are the RAM, ROM, EEPROM and the Bootstrap loader. The RAM, also known as Random Access Memory, is the temporary space where the processor places the data while it is being used. This allows the computer to find the information that is being requested quickly without having
Q:1What is the difference between cache memory and RAM?(5 lines only) Ans: RAM is abreviated as Random Access Memory, is the main memory of computer in which the running programe is stored temporarily , it losts its memory when computer is turned off. While Cache memory is a special memory used to decrease the average time taken by RAM to access the programe. Cache memory is smaller memory as compared to RAM but it is much faster then RAM. Q:2There are three types of printers what are they? Give
Visual impairment and blindness caused by various diseases has been hugely reduced, but there are many people who are at risk of age-related visual impairment. Visual information is most important for any navigational tasks, so visually impaired people are at disadvantage because necessary information about the surrounding environment is not available. With the wide development in inclusive technology it is possible to extend the support given to people with visual impairment during their mobility
Microcontrollers Microcontroller can be considered as a small size of computer on a chip. Because it consists of processor, random access memory (RAM), read-only memory (ROM) and input/output peripherals. Microcontroller is also named as embedded controllers, since it is part of an embedded system. According to Blacharski (2003) microcontroller defines as “an integrated chip that is often part of an embedded system”. The purpose of develop microcontroller is to evolve the performance and efficiency
Planned obsolescence, according to the Collins English Dictionary, is “the policy of deliberately limiting the life of a product in order to encourage the purchaser to replace it.” Planned obsolescence is the idea that a product is designed to fail, or fall out of style, rather than being designed for longevity and durability (Hindle; Landes). Planned obsolescence has occurred in many industries such as the textile and automobile industries (Hindle; Landes). Items such as dresswear and cars become
PIC microcontroller Brief History The first microprocessor was developed by a small company called Intel (Integrated Electronics) in the early 1970s. But it faced no consumer market so they decided to market the chipset as “general purpose” microprocessing system where digital logic chips would have been used. This idea was a success and the Intel team developed 4 bit microprocessor called the 4004. In 1974, the second generation microprocessor (the 8080) was fabricated as a single chip operated
The ARM1176JZF-S (which I will refer to just as ARM) microprocessor belongs to the ARM11 family and uses ARMv6 32-bit RISC architecture. The AVR has a 2 stage single level pipeline, which is a simple pre-fetch and execute system. The ARM however has a much more complex pipeline system. It uses a 8-stage dual level pipeline; fetch1, fetch2, decode, register, shift, data1, data2 and write-back. This has many advantages over a basic 2 stage pipeline. Parallelism within an instruction allows continued
Inter IC Communication:- Inter IC Communication bus, often abbreviated as I2C bus, is a multi-master bi directional 2 wire serial bus for Inter IC communication, developed by Philips Semiconductor. The I2C bus consists of only two lines; one is called SDA (Serial Data line) carries the data bits and the other is called SCL (Serial Clock Line) is used as a clock signal. The messages sent over the I2C bus contain addresses to define which device should reply to them. All I2C-bus compatible devices
Writing a "Private 3M Script" First it is important to define the term "3M." The term "3M" simply refers to a script's ability to unlock all of the channels, based on the saying "All for one, and One for all!" from the "3 Musketeers," (which came from the old days of hacking cable boxes where all channels were viewable through one channel). Anyway, "3M" now is just a generic term for a card that has all channels open and no stealth or write protection. In stealth scripts, the "3M" code refers to
minimize power consumption and gain processing speed. ATmega 16L consists of 40-pin IC and belongs to the mega of AVR family. Features and architecture of ATmega 16: Features of Atmega16 include: • 16KB of Flash memory • 1KB of SRAM • 512 Bytes of EEPROM • Available in 40-Pin DIP • 8-Channel 10-bit ADC • Two 8-bit Timers/Counters • One 16-bit Timer/Counter • 4 PWM Channels • In System Programmer (ISP) • Serial USART • SPI Interface • Digital to Analog Comparator. • Watchdog timer

1. What types of printers are most common today? What is the cost of a color printer versus a black-and-white one? Compare and contrast laser and inkjet printers in terms of speed, cost, and quality output. What kind of printer would you buy or have you bought? Ans: Most Common types of PRINTERS Inkjet printers Inkjet printers squirt little dabs of ink onto the page to imitate content and pictures. Inkjets are famous on the grounds that they're generally modest. There are additionally numerous models
Computer Architecture 1. There have been a lot of developments in microprocessors since the 286 chip. The 286 CPU are no longer sold and are very rarely found in commercial use today because of its running speed, which is between 10MHz to 20MHz. This processor has a 24-bit address bus, and is able to address up to 16 million different address locations. It also has two operating modes, which are real mode and protected mode. The real mode is basically for normal DOS operations and it uses only
