Homework – Identifying computer related terms and critical thinking questions. 1. Identify and/or describe each of the following computers related terms. Bit: Comes from the phrase “Binary DigIT.” A bit is a single digit number in base-2 (a zero or a one) and is the smallest unit of computer data. A full page of text is composed of about 16,000 bits. Byte: A byte is a unit of measurement used to measure data. One byte contains eight binary bits, or a series of eight zeros and ones. Therefore, each byte can be used to represent 2^8 or 256 different values. Computer: A programmable machine. This means it can execute a programmed list of instructions and respond to new instructions that it is given. Input: Whenever you enter data into your computer, it is referred to as input. This can be text typed in a word processing document, keywords entered in a search engine’s search box, or data entered into a spreadsheet. Output: Data generated by a computer is referred to as output. This includes data produced at a software level, such as the result of a calculation, or at a physical level, such as a printed document. Processing: A process is a program that is running on your computer. This can be anything from a small background task, such as a spell-checker or system events handler to a full-blown application like Internet Explorer or Microsoft Word. All processes are composed of one or more threads. Storage: A computer storage device is any type of hardware that stores data. The most common type of storage device, which nearly all computers have, is a hard drive. The computer’s primary hard drive stores the operating system, applications, and files and folders for users of the computer. 2. Critical Thinking Skills
