Nurgali Diana Laboratory work 4. Peripheral devices and storage devices and media. Question 1. Researching a Computer System Visit the site of a computer vendor. Assume that you have a budget of $1,200 and put together the specification for a computer that is appropriate for a college student studying Computer Science. Диагональ 16,1″ - 40,64 см Процессор Intel® Core™ i5 Операционная система Linux Объем оперативной памяти 8 GB Тип жесткого диска SSD Объем накопителя 256 GB Серия видеокарты Intel Iris Xe Graphics Чипсет видеоадаптера Iris Xe Объем памяти видеоадаптера SMA (выделяется  Assume you're buying a notebook computer for a businessperson who is a frequent airline traveler and is concerned about weight and battery life. What can you get for $2,500? А  ккумулятор •аккумулятор 70Вт/ч •накопитель 1ТБ PCle 4.0 •память 16Гб • металическая прочная коронка •водонепроницаемый корпус •18,9мм/ 1,8кг тонкий и легкий форм-фактор Question 2. I/O a) Define I/O device. b) Consider that a computer requires I/O devices to be able to interact with its environment. Explain why it is necessary for computers to have these devices. c) Give four examples of I/O devices. d) For each I/O device in your answer to part c, explain the device's function from the perspective of a user. Question 3. RAM Define RAM. RAM (Random Access Memory) RAM is the main memory in a computer. It is much faster to read from and write to than other kinds of storage, such as a hard disk drive (HDD), solid-state drive (SSD) or optical drive. What is the unit of measurement typically used for the speed of RAM? On a practical scale, memory is measured in kilobytes (KB) or megabytes (MB). A kilobyte is not, as one might at first expect, 1000 bytes. c) With regard to RAM, what is volatility? Question 4. Benchmarks Fresh Diagnose is a utility designed to analyze and benchmark your computer system. It can analyze and benchmark many kinds of hardware, such as CPU performance, hard disk performance, video system information, mainboard / motherboard information, and a lot more besides. System Information: Scan your system and get a complete report about your computer's hardware and software, for example: motherboard information, video system information, PCI / AGP buses information, peripheral (keyboard, mouse, printer, etc.) information, network information. With regard to computing, define the term benchmark. A benchmark computer is a computer used to provide a specific calculation of how fast a certain computing task can be accomplished with specific hardware. b) What tasks does benchmarking software perform in order to measure the system being tested? c) How can consumers use benchmarks to help them purchase a computer system? d) How do benchmarks help identify slow points (bottlenecks) in the system? Question 5. Port Identification Consider the following devices: Mouse Printer Keyboard Modem Speaker Digital camera Ethernet jack Monitor For the following questions, indicate which device(s) should be plugged in which port(s) A-H shown in the diagram below.  a. What device(s) can be plugged into port A? i. What is the name of this port? Клавиатура и мышь Порт PS/2Компьютерный порт, применяемый для подключения клавиатуры и мыши, использующий 6-контактный разъём mini-DIN. ii. Is this a serial port or parallel port? Parallel port b. What device(s) can be plugged into port B? i. What is the name of this port? Display Port ii. Is this a serial port or parallel port? Parallel port c. What device(s) can be plugged into port C? i. What is the name of this port? Разъём VGA ii. Is this a serial port or parallel port? d. What device(s) can be plugged into port D? i. What is the name of this port? DB-25 ii. Is this a serial port or parallel port? Serial ports e. What device(s) can be plugged into port E? Аудио разъём mini-jack разъем для колонок окрашен в зеленый цвет, для наушников в красный, а синим цветом окрашен разъем для линейного входа. f. What device(s) can be plugged into port F? VGA Это аналоговое соединение приводит к искажению сигнала на более длинных кабелях g. What device(s) can be plugged into port G? DisplayPort DisplayPort сегодня является наиболее передовым стандартом соединения мониторов с компьютером h. What device(s) can be plugged into port H? Сетевой порт Ethernet (RJ-45) Этот порт позволяет напрямую подключаться к проводным сетям. Порт для соединения роутера с компьютером для выхода в интернет по средствам сетевого кабеля |
