IT Basics
The missing function of a computer system from this list of functions: Input, Data Processing, Storage and _______________ .
What is Output?
This is a group of computer systems that are interconnected to share information with each other.
What is a network?\
This is a type of input device: Speakers, Monitor, Touchscreen, or Hard drive
What is a Touchscreen?
This is a computer program that allows people, hardware, and software to interface with each other.
What is an operating system (OS). Operating systems are software that can communicate with a computer's hardware, provide a user interface to accept commands, allow applications to run, maintain a filing system, and have built in security features.
This refers to the digital content that is delivered over the Internet, usually through a browser.
What is the Web?
This numbering system uses sixteen digits. It uses the numerals 0 through 9 and the letters A through F, where A=10, B=11, C=12, D=13, E=14, and F=15.
What is the hexadecimal number system. There are two numbering systems used to express numbers that are used by computers: binary and hexadecimal. Binary represents physical signals inside the computer and hex is an easy way for humans to represent binary numbers.
This is a combination of technology, people, and procedures used to organize, analyze, and store data.
What is an information system? A system is a set of connected parts or procedures that lead to something being accomplished. For example, a car uses a steering system, an electrical system, and a braking system to travel to its destination. Similarly, an information system is a combination of technology, people, and procedures used to organize, analyze, and store data. These different parts of the system are used together to improve processes and increase an organization's value.
This is a place where data can be temporarily stored on: Printed page, Keyboard, Memory chips, or Hard drive.
What is a hard drive?
Message boards, conferencing software, email, and calendaring are all examples of this type of software.
What is Collaboration Software?
They manage an access point to the Internet.
What are Internet Service Providers, or ISPs? They don't manage the entire Internet. If you think of the Internet as a big freeway, then ISPs manage the on-ramp to the freeway. They're responsible for building the on-ramp and keeping it maintained and open, but they're not responsible for the Internet itself.
8 of these are equivalent to one byte.
What are bits. A bit is the smallest unit of digital information. Each individual one and zero in a binary sequence is a bit. Computers work by translating physical signals, such as electrical charges, into digital information. They do this by encoding each signal as either a 1 or a 0.
Because computers can't understand and accept instructions from regular human speech they rely on these line-by-line instructions about what it should do, such as C, C++, C#, Python, Java, and JavaScript.
What are Programming Languages?
This provides a computer system with the ability to retrieve and manipulate data at a future time: Storage, Microchip, Transistor, or Processing.
What is storage?
This software helps an operating system communicate with hardware devices, such as printers, video cards, scanners, and cameras.
What is device driver software? The driver translates signals from the operating system into instructions the hardware can understand.
Every computing device that accesses the Internet is assigned a unique one of these.
What is an IP Address? Every computing device that accesses the Internet is assigned a unique Internet Protocol (IP) address.
This is a general term refers to everything that involves computers
Information Technology (IT).
This is the process of turning data points into useful information, in which the first step of the process is to collect raw data.
What is data analytics?
This is the most important part of any modern computer system and is considered the "brain" of the computer.
What is the CPU? The CPU controls the other parts of the computer by getting information from them, then telling them what to do.
This is read-only software preinstalled on a device that tells the device how to work, which is often released by manufacturers to update.
What is Firmware? Firmware can be found in televisions, remote controls, game consoles, printers, cameras, music players, and even automobiles. Sometimes, manufacturers release firmware updates that fix bugs and add new features.
This is a protocol that associates domain names (such as web servers) with unique IP addresses.
What is DNS, short for Domain Name System? DNS servers translate URLs into machine-readable IP addresses.
This is the NEXT step in the computing process after a user has entered a search string into an application and clicked on the search icon.
Which is processing?
These are electronic repositories of organized information.
What are Databases?
This is used to connect computers to the internet and can sometimes be built in the motherboard.
What is the Network Interface Card, or NIC.
This software is contained on a memory chip on the computer's motherboard. It is the first software that's run whenever a computer is started. .
What is Basic Input/Output System (BIOS) software. The BIOS runs the computer until the operating system takes over. It's non-volatile, which means its settings are saved and can be recovered after the device has been powered off.
This is a suite of protocols or rules that facilitate Internet communication.
What is TCP/IP (Transmission Control Protocol/Internet Protocol)?
This provides a computer system with the ability to retrieve and manipulate data at a future time.
What is storage?
This is a network of connected devices localized in a single physical location, such as in a single office building, private residence, or other business. But, can range in size from a few devices in someone's home to thousands of users in a large company under the same roof.
What is LAN or local area network?
A computer stores information in this location. It is where where the computer loads the instructions into, the processor gets the first line of instructions from here, executes the instruction, and writes the result back into here to use later. It is extremely fast, but it’s also volatile.
What is RAM, or random-access memory?
This type of software is used to perform common tasks in a business or home office and includes software applications to make it easy to write a report, perform a budget analysis, prepare a business presentation, and conduct online research.
What is Productivity software?
This refers to the network of physical devices that are connected to the Internet and capable of communicating and sharing data through sensors, network connectivity, and other technologies.
What is the Internet of Things?
