• Vacuum Tubes where used for circuitry and magnetic drums for memory. They

often malfunctioned because of the excessive heat they generated. Punched cards were used for input, and the computers printed out the outputs.

• Transistors were more reliable and economical. The smaller electronic

components in the second generation could maintain two states, "Off" and "On," represented by the binary digits 0 and 1, respectively. Second-generation computers still relied on punched cards for input and printouts for output. Tapes and disks were used for storage purposes.

• integrated circuits enabled the development of computer systems that were

cheaper, faster, smaller, and more reliable. Users interacted with third-generation computers using keyboards and monitors that communicated with the other components of the hardware and operating systems.

• Microprocessors include thousands of integrated circuits on a single silicon

chip. This generation of computers is characterized by a significant reduction in processor size and, at the same time, a significant increase in capabilities.

• The fifth generation will rely on A.I., Quantum computing, or nanotechnology.

Which low-level language corresponds one-to-one with assembly?1)Translator language 2) Machine language 3) Compiler language 4) Programming language 2) Machine language Machine language is what the Computer reads A compiler translates source code into machine language. A compiler checks source code for errors before translating it into object code.Compiled languages are also known as programming languages. A compiler takes all instructions written in the program and translates it all at once into machine code.Interpreters translate and execute source code into machine language one line at a time. If the interpreter finds an error, the process is terminated at the statement containing the error and displays an error message.What is a cloud model that delivers third-party software such as email or games through the internet?1) IaaS 2) SaaS

3) RFID

4) PaaS 2) SaaS There are Three Service types 1) Infrastructure as a service (IaaS) The IaaS model provides access in a virtualized environment and the computing resources are composed of virtualized hardware.2) Platform as a service (PaaS) In the PaaS model, customers have access to a platform that supports the development and management of web applications.3) Software as a service (SaaS) With the SaaS model, the software is licensed to customers with subscriptions and central hosting. Some examples include Gmail, Google Docs, and Microsoft Office 365.What is one of IT's roles in globalization?1) It provides support for JIT manufacturing.

2) It allows companies to achieve ISO 9001:2008

certification.3)It provides tax havens for companies.4) It allows companies to reach a wider customer base.4) It allows companies to reach a wider customer base.Advancements in computer hardware, software, and networking have increased people's ability to access information and reach economic potential.Which category of computer has an external flat screen monitor, optical disk drive, and a large capacity hard drive?1) Handheld 2) Laptop 3) Desktop 4) Mainframe 3) Desktop Computers are categorized based on their size and processing speed.Supercomputers are the biggest and fastest computers, designed to process huge amounts of data.Mainframe computers are designed to support hundreds or thousands of users simultaneously.A workstation is a single-user computer designed for technical or scientific applications.A microcomputer is more commonly known as a personal computer. It is a general-purpose computer for individual use. Desktops, laptops, and handheld or mobile devices are all microcomputers.

Which two software application packages would be classified as productivity software? Choose 2 answers 1) E-mail 2)Word processor 3) Spreadsheet program 4) FTP client 2)Word processor 3) Spreadsheet program There are three software classifications Productivity Software Software that people use to complete daily tasks is called productivity software.Productivity software is used to complete tasks such as writing documents, managing personal information, giving presentations, and storing data.Collaboration Software Collaboration software helps people communicate and work with one another, and helps computers share information.Specialized Software Specialized software performs tasks for specific purposes. Professions such as computer-aided design, medicine, science, finance, games, and entertaining use specialized software.Which two computer peripherals are connected to the computer through a port?Choose 2 answers

1) DVD

2) PC card 3) External microphone 4) Camera card 5) USB flash drive 3) External microphone 5) USB flash drive Various units that support the input and output functions are collectively called peripheral devices and comprise the I/O unit. Input devices, such as keyboards, mouses, and sensors, are used to move data into computers. Output devices, such as printers and monitors, are used to move information out of computers.Which term is defined as a collection of information used to support management of an organization?1) Information Technology 2) Information Security 3) Information System 4) Information Archiving 3) Information System There are five disciplines in IT Computer engineering (CE) focuses on the design of hardware systems and the software that makes them work.Computer science (CS) addresses the design and implementation of software with an emphasis on developing effective ways to solve computing problems and creating new ways to use computers.Software engineering (SE) focuses on the development and maintenance of reliable and efficient software systems.The focus of information systems (IS) is to integrate IT solutions meant to meet organizational business goals.Information technology (IT) focuses more on the technology supporting information systems in an organization rather than the information residing on the systems or being communicated with them.

A website logs the timestamp, location, and browser of every visitor. It then aggregates this content into peak traffic times and days, minimum and maximum hits for each country and region, and popularity of certain browsers among visitors.What is the timestamp considered in this scenario?1) Data 2) Information 3) Knowledge 4) Wisdom 1) Data Information is a collection of processed data from a variety of sources.Data is continually aggregating and is not useful until it has been processed and is presented in a usable form. Data includes raw facts or observations.Information can be structured or unstructured, and the key term associated with it is meaning.Knowledge is a dynamic combination of experience, values, contextual information, expert insight, and grounded intuition that provides an environment and framework for evaluating and incorporating new experiences and information.Wisdom is knowing the right thing to do with the knowledge.A departmental manager is creating a budget estimate for the upcoming year.
