Xin có vài lời với các bạn gần xa,mình đang học diploma về IT(information of technology) ở Auckland, mình chỉ mới bắt đầu tìm hiểu về máy tính trong 1,2 năm gần đây,trong các môn mình học có môn IT concept tạm dịch là khái niệm về IT, sau đây là một số câu hỏi trong assignment đầu tiên,vì mình vừa đi học vừa đi làm thêm partime job nên không đủ thòi gian làm rất mong các bạn yêu thích tin hoc ở việt nam hoặc đang ở các nơi trên quả địa cầu giúp đỡ, vô cùng cảm tạ...............
sau đây là một số câu hỏi mang tính khái niệm.....
07 What is the process of turning analogue video or audio into digital data form called?
08 A TV remote control transmits an ID plus a byte of data to the Infra Red receiver on the television. How many different command sequences can be transmitted with a byte of data?
09 If we add one more bit to the command word in ten, above; how much does it increase the number of commands by?
10 What is the general rule relating the number of discrete states that can be represented, to the number of bits being used? (2 marks)
11 What is the purpose of Unicode? (2 marks)
12 On a video card , the output to drive a monitor is an analogue signal ( although that will change soon , too) .What device on the video card converts the data into an analogue signal for the monitor? (2marks)
13 In general what is the process called that converts digital data into a real world, analogue signal? (2 marks)
14 What is the difference between Standard ASCII and Extended ASCII ? (2 marks)
15 Who developed EBCDIC? Where is it used today? (2 marks)
16 What is the difference between a digital computer and an analogue computer? (2 marks)
17 Find and list one place where an analogue computer is used today. (2marks)
18 Briefly describe the process that allows music to be converted into a form suitable for storage on digital media. (6 marks)
Section C The CPU Environment (34 marks)
21 Describe the function of the following CPU sub assemblies, based on a generic model of a CPU. (18 marks)
· Addressing Unit
· Execution Unit.
· Control Unit.
· L2 Cache
· General Purpose Registers
· Decoding Pipeline(s)
22 There are three broad categories describing approaches to CPU architecture. CISC, RISC and VLIW. Describe each of these, and list at least one CPU type that uses each. (9 marks)
23 DRDRAM Rambus is expensive , but appears to offer very high performance .It does, however, have one significant design fault that makes it’s specification appear better than it really is. Find out what the problem with Rambus performance is, and describe it here. (7 marks)
Section D. The data communications environment (34 marks)
24 Define the term ‘modem’. (2 marks)
25 Describe three differences between ADSL modems and V.90 modems.
(6 marks)
26 What two definitions of the word ‘bandwidth’ are used? (4 marks)
27 Satellites communications may have difficulty and provide poor quality service under some circumstances. List and describe three potential difficulties with satellite based data communications. (6 marks)
28 Describe the difference between a switch and a hub in a LAN (8marks)
29 Draw and label the following common network topologies: ( 4 marks)
Bus
Ring
Star
Mesh
