2.1 What exactly is a computer, and what are its four main functions?
2.2 What is the difference between data and information?
2.3 What are bits and bytes, and how are they measured?
- Know abbreviation and approximate number of bytes for each of the following
- kilobyte, megabyte, gigabyte, terabyte
- Given size in one unit, be able to convert to another. For example, given KB, be able to convert to MB.
- 1 KB = 1,000 B = 0.001 MB
- 1 GB = 1,000 MB = 1,000,000 KB = 1,000,000,000 B
2.4 What devices do you use to get data into the computer?
- QWERTY vs. Dvorak keyboard
- Different types of mice
- Items from textbook plus those discussed in class (touchpad, pointing stick, digital pen, Surface, OCR, OMR, barcode reader, RFID)
2.5 What devices do you use to get information out of the computer?
- Printers: inkjet, laser, multifunction
2.6 What's on the front of your system unit?
2.7 What's on the back of your system unit?
2.8 What's inside your system unit?
- Key terms (see p. 84): binary digit (bit), binary language, byte, central processing unit (CPU, or processor), connectivity port, data, drive bay, Dvorak keyboard, ergonomics, Ethernet port, expansion card (adapter card), expansion slot, gigabyte (GB), hard disk drive, information, inkjet printer, input device, kilobyte, laser printer, megabyte, modem port, nonimpact printer, nonvolatile storage, parallel port, port, QWERTY keyboard, random access memory (RAM), serial port, system unit, toggle key, touchpad, trackball mouse, video card, volatile storage,
5.1 What software is included in system software?
5.2 What are the different kinds of operating system?
5.4 How does the operating system provide a means for users to interact with the computer?
5.6 How does the operating system manage memory and storage?
5.7 How does the operating system manage hardware and peripheral devices?
5.11 How does the operating system help me keep my computer organized?
5.12 What utility programs are included in system software, and what do they do?
- Key terms (see p. 246): command-driven interface, device driver, Disk Cleanup, disk defragmenter, file compression utility, file management, file path, graphical user interface (GUI), menu-driven interface, multitasking, multiuser operating system, operating system, Plug and Play (PnP), real-time operating system, single-user multitask operating system, single-user single-task operating system, spooler, swap file, system software, Task Manager utility, Task Scheduler utility, thrashing, user interface, utility program, virtual memory
This chapter contains a lot more detailed information on topics from chapter 2. Concentrate on understanding the key terms below.
6.1 How can I determine whether I should upgrade my existing computer or buy a new one?
6.2 What does the CPU do, and how can I evaluate its performance?
6.3 How does memory work in my computer, and how can I evaluate how much memory I need?
6.4 What are the computer's main storage devices, and how can I evaluate whether they match my needs?
6.7 What are the ports available on desktop computers, and how can I determine what ports I need?
- Key terms: arithmetic logic unit (ALU), cache memory, control unit, front side bus (FSB), gigahertz (GHz), megahertz (MHz), L1 cache, L2 cache, Moore's Law, motherboard
Excel will be covered on the Final Exam since you'll have more time. However, other skills discussed in class will be evaluated using Word:
- Be able to identify ports for a given computer (similar to the hardware lab)
- Creating screen shots: Use Print Screen and ALT+Print Screen. Save to Word document
- My Computer: Change Views between detail, list, icon
- Save a file in Rich Text Format
- Create a zip file
- New Word skills used in Hardware Project (http://delicious.com/npnapier/itec1001_hardware_lab)
- Creating a cover page
- Creating a table of contents
- Creating a table of figures
- Inserting a chart
