SPECIFIC EXPECTATIONS
By the end of this course, students will:
A1.1 identify basic electronic components and describe their functions (e.g., resistors limit cur- rent; capacitors store charge, pass high frequencies, and block DC; diodes restrict current in one direc- tion; LEDs indicate current flow; transistors act
as amplifiers or switches);
A1.2 use precise terminology to identify various types and features of computer hardware and interfaces (e.g., device name, capacity, speed, bandwidth, connector types);
A1.3 identify the basic components and peripheral devices of a computer system (e.g., mainboard, CPU, power supply, hard drive, monitor, mouse, sound card, printer, scanner), and describe their functions;
A1.4 describe important advances in electronic components (e.g., development of semiconductor technology) and computer components (e.g., clock rates, fabrication techniques, bus types).
By the end of this course, students will:
A2.1 compare various types of networks (e.g., local area network [LAN] versus wide area net- work [WAN], peer-to-peer versus client-server);
A2.2 describe the basic components of a network (e.g., workstations, server, network interface cards, routers, switches, hubs);
A2.3 compare the various types of data transmis- sion media for networks (e.g., fibre-optic cable, copper cable, wireless);
A2.4 describe how individual workstations are identified on a network (e.g., logical and physical addressing, verification utilities).
By the end of this course, students will:
A3.1 describe binary numbers, and convert posi- tive integers between binary and decimal num- ber systems (e.g., convert 24710 to binary, convert
111101112 to decimal);
A3.2 describe how computers represent and process data using the binary number system (e.g., binary counting, binary codes, ASCII code);
A3.3 derive the truth tables of the fundamental logic gates (e.g., AND, OR, NOT, NOR, NAND, XOR);
A3.4 write Boolean equations for the fundamental logic gates (e.g., for AND, the output is Y = A • B; for OR,Y = A + B).
