Assignment assigned by Mr. Tri Djoko Wahjono (A)True/False Mark T for True and F for False. 1. The system unit is a case that contains electronic components of the computer used to process data. (210) (T) 2. The processor holds data waiting to be processed and instructions waiting to be executed. (213) (F) 3. The speed of the system clock is just one factor that influences a
computer’s performance. (216) (T) 4. Replacing a motherboard is a fairly complicated process, whereas replacing a processor is much simpler. (218) (T) 5. A byte is the smallest unit of data the computer can process. (221) (F) 6. When the computer’s power is turned off, volatile memory loses its contents. (223) (T) 7. Current processors include advanced transfer cache (ATC), a type of L2 cache built directly on the processor chip. (227) (T) 8. Read-only memory refers to memory chips storing permanent data and instructions. (228) (T) 9. Hi-Speed USB is a more advanced and faster USB, with speeds 100 times higher than that of its predecessor. (234) 10. USB 3.0 is more than 10 times faster than USB 2.0. (234) (T) 11. Both USB 2.0 and USB 3.0 are backward compatible, which means they do not support older USB devices. (234) (F) 12. SAS (serial-attached SCSI) is a newer type of SCSI that transmits more reliably, but at slower speeds, than parallel SCSI. (235) (F) (B)Multiple Choice Select the best answer.
(C) Matching Match the terms with their definitions.
(D)Short Answer Write a brief answer to each of the following questions. 1.a. Slate Tablet PC , which typically does not include a keyboard, the system unit is behind the display. b. Convertible Tablet PC, by contrast, the system unit is positioned below a keyboard, providing functionality similar to a traditional notebook computer The difference is the display attaches to the system unit with a swivel-type hinge, which enables a user to rotate the display and fold it down over the keyboard to look like a slate Tablet PC or netbook. 2. The motherboard, sometimes called a system board, is the main circuit board of the system unit. The motherboard contains many electronic components including a processor chip, memory chips, expansion slots, and adapter cards. A computer chip is a small piece of semiconducting material 3. The machine cycleis a set of four basic operations — fetching, decoding, executing, and storing — that the processor repeatsfor every instruction Register functions include storing the location from where an instruction was fetched, storing an instruction while the control unit decodes it, storing data while the ALU computes it, and storing the results of a calculation 4. Many computers, peripherals, smart phones, PDAs, cars, and other consumer electronics are Bluetooth enabled, 3 ways of making Bluetooth enabled computer:
5. Compressed air can be used to blow dust away from any unreachable by normal cleaning. For cleaning computer we should turn it off, and if necessary, unplug it from the electrical outlet, remove the battery, and disconnect all cables from the ports. What is the most common type of volatile memory?Flash memory is the most common type of volatile memory, which loses its contents when you turn off the power to the computer. 3. A memory chip is the most important hardware component in a computer.
Which of the following is a case that contains electronic components of the computer used to process data?System Unit is a case that contains electronic components of the computer used to process data.
Is the amount of time it takes the processor to read from memory?With computer memory, access time is the amount of time it takes the computer processor to read data from the memory. When looking at the access time of memory it may be represented in either ns (nanoseconds), MHz, or GHz.
What technology provides high speeds and consumes little power?CMOS complimentary metal-oxide semiconductor technology because it provides high speeds and consumes little power.
