CGS2060 Mid-Term ExamStudy Guide Chapter 1 Topics: - What can you use computers for- - combines hardware and software to accept the input of data, process and store the data, and produce some useful output- When you talk about something digital it references things that can be represented by numbers- Bit- represents data using 1’s and 0’s- Digitization is the process of transforming information into 1’s and 0’s- A group of 8 bits is called a byte- Things that can be stored on a digital device include numbers, characters, sounds, images, movies,etc. - Know what a special purpose computer is- A kiosk is a computer station that provides the public with specific and useful information and services.- Know the general definition of a computer network- A telecommunications network that connects two or more computers for data communications.- Telecommunications are communications that take place electronically over a distance- Know that Wi-Fi (short of wireless fidelity) is a popular wireless networking standard- Wireless networks use radio signals rather than cables to connect users.- VOIP (Voice-over-Internet-Protocol) is a popular technology that allows phones to use internetconnections. - The speed of a human brain has been estimated at 100 trillion operations per secondChapter 1 Outline/Summary- Computer- A digital electronics device that combines hardware and software to accept the input ofdata, process and store the data, and produce some useful output.- Technology refers to tools, materials, and processes that help solve human problems. - Digital electronics devices store and process bits electronically.- General-purpose computers can run any number of software applications- Special-purpose computers are designed primarily for one particular function- Data: items stored on a digital electronics device: numbers, characters, & sounds- Information: data organized and presented in a manner that provides value to the user: documents, graphs, music, photos- Microprocessor- Sometimes called a chip or just a processor, combines microscopic electroniccomponents on a single integrated circuit that processes bits according to software instructions.- computing platform A computer’s type, processor, and operating system define its.- Mobile Media- Movies, television shows, and other video clips can be downloaded from the Web or transferred from DVD to the devices and displayed on the 3.8-inch screen.- Internet is the world's largest public computer network, a network of networks, that provides a vast array of services.- The Web is an Internet service that provides convenient access to information through hyperlinks- Wireless networks use radio signals rather than cables to connect users.- Wi-fi is a popular wireless standard- Computers were invented to compute – calculate solutions to mathematical problems.Automation involves utilizing computers to control otherwise human actions and activities- A Computer-based Information System (CBIS) uses these components to manage and distribute information.- Information Technology- IT can be defined as issues related to the components of a computer-based information system.- Information security refers to the protection of information systems and the information they manage against unauthorized access, use, manipulation, or destruction, and against the denial of service to authorized users.Chapter 2 Topics: - Know that data is stored as bits (binary)- Bits are the 1’s and 0’s that allow us to represent, store, and manipulate data- They are the smallest unit of data in a digital electronics device- Know basic counting with binary numbers- Information can be assigned to the two states of the bit: On OR Off- Know what an Arithmetic Logic Unit (ALU) is- contains the circuitry to carry out the instructions in the processors instruction set- Know that the Front Side Bus consists of electronic pathways between the CUP and RAM- The system bus connects the CPU to the chip set, and through it to RAM and other components on the motherboard.- Know that clock speeds are measured today in Gigahertz and Megahertz- Know the different storage (RAM, ROM, CMOS) and know which one is the largest- Secondary storage is used to store data more permanently without the need for electricity- Random Access Memory (RAM) is temporary, or volatile, memory that stores bytes of data and program instructions for the processor to access.- ROM- Read-only memory. A class of7storage7media used in7computers7and other electronic devices. Data stored in ROM cannot be modified. LARGEST- CMOS- Complementary metal-oxide-semiconductor7(a technology for constructing integrated circuits.)- Know that RAM consists of chips grouped on a board called SIMM- Look up the capabilities and properties of Magnetic Tape- High-capacity Disks & Floppy Disks (outdated)/Microdrives - Know that Flash Memory - is a form of Solid State storage- Know that notebook computers - integrate the mouse as touch-sensitive pad called the touch padChapter 2 Outline/Summary- Bits are the 1’s and 0’s that allow us to represent, store, and manipulate data- They are the smallest unit of data in a digital electronics device- A bit can be a capacitor that is electronically charged or not charged.- A bit can be an area of metal particles on the surface of a disk that are either magnetically charged or not. A bit can be a microscopic spot on a highly reflective disk surface that either has a pit burned into it or not.- Anything that can be expressed through words, numbers, sounds, pictures, and even scents can be digitized.- Digital information is easy to manipulate.- Digital information is easy to copy and transfer.- Digital information is long lasting.- Digital convergence is the trend to merge multiple digital services into one device.transistor is an electronics component, composed typically of silicon, that opens or closes a circuit to alter the flow of electricity to store and manipulate bits.Integrated Circuit (chip) combines transistors and capacitors in a tiny module to store and process bits and bytes in today’s digital electronic devices- Central Processing Unit (CPU) is a group of integrated circuits that work together to perform the processing in a computer system.motherboard is the primary circuit board of a computing device that houses the digital device’s circuitry including the microprocessor and memory.- The microprocessor accesses instructions stored in memory over the system bus.-
