It uses voice communications and then gets sent back to the base station. Data technology is also used on smartphones which allow the user to browse the internet and download files. Landline Phones – Landline phones typically only use voice communications. Some newer landline phones can use what is called a NCID (Network Caller ID) which uses data sent over a TCP connection. SMS/Text Messaging – The SMS (Short Message Service) can be used in a variety of ways.
(1.0 points) Computer graphics that unlike raster graphics, are represented as geometric shapes by mathematical equations. Vector graphics are generated by illustration software such as adobe illustrator. 4. Which type of computer graphic can be resized without affecting image quality or getting distorted? (1.0 points) A vector graphic Lesson 3 (5.0 points) 1.
Approximately 20 drops of a .04% Bromothymol blue solution was then added to the beaker of the phosphate buffer. Using a clean 5 mL serological pipette, transfer 5 mL of the phosphate buffer and Bromothymol blue solution to each of three clean 150 mL beakers. Next, using the buret for HCl, add 1 mL of HCl to one of the three beakers, then label this beaker “Yellow”. Next use the buret for NaOH and add 1 mL of NaOH to another of the three beakers, and label this beaker “Blue”. Lastly add 1 mL of water using the buret for water to the last beaker, and label this beaker “Green”.
Purpose The purpose of this experiment is to see the effect that paper chromatography has on ink. Materials • Four different markers (including one black permanent marker) • Rubbing alcohol or isopropyl alcohol • Coffee filters (2) • Tall glasses or plastic cups (2) • Pencil • Ruler • Tape • Table salt • Water • Measuring cups/spoons • Clean pitcher or 2-liter bottle Procedure 1. Coffee filters usually are round, but it's easier to compare your results if the paper is rectangle. So, your first task is to cut the coffee filter into a rectangle measuring three cm by nine cm. You will need two of these strips to complete the lab.
Take a screen shot of the Network Map window by pressing Alt+ Prt Scr, and then paste the resulting image into the Lab03_worksheet file in the page provided by pressing Ctrl + V. * Exercise 3.3 | Manually Configuring TCP/IP | Overview | Because the lab network you are constructing for Contoso, Ltd. must be isolated from the production network, you do not want lab computers to obtain their TCP/IP settings from the DHCP servers on the production network. Therefore in Exercise 3.3 you manually configure the TCP/IP client to use static IP addresses. | Completion time | 15 minutes | 3. Using the information in the IPconfig.exe
Which of the following determines, in part, what bits the computer stores in RAM to represent the number 123456789? B 8. Which of the following is not a feature of a file system that might be used with a hard disk drive? A 9. A student writes a report using a word processor, saving the report in a file called my_report.
Capturing emission spectra from discharge tubes is discussed in the experiment guide. Create a procedure of no more than 5 steps that you can use to identify the wavelength values for the emission lines of the helium spectrum. 1. Connect the Spectro Vis Plus spectrometer to the USB port of a computer. The white cable is the USB cable.
4.4.3 Noise SMF Crosstalk Coaxial Interference Coaxial Op en (Open Circuit) UTP Short (Short Circuit) MMF Break UTP 4.4.4 I first start with my anti-virus to run any scans, after that I go into my device manager and click the network adapter. I then will go into my general tab and click trouble shoot. 4.4.5 Some of the common strategies for trouble shooting from top down starts with are you able to view a web page in your browser, can you se nd or receive email and/or are your username and password correct, and are your Interne t Explorer connection settings correct. If none of those are an issue you take it a little further. Is there a firewall configured on your computer, is your firewall block ing ports, if you turn off the firewall does it resolve your problem?
Unit 7 Assignment 1: Video Summary 5 Explain BIOS: Basic Input/ Output System * BIOS tells the hardware how to operate with the computer’s Operating System * BIOS is built into the motherboard and is standard on all computers * BIOS can be used to tune the computer’s hardware * A specialized key stroke is used to enter into BIOS before the system fully boots up * BIOS can only be navigated using key strokes (mouse will not work) * The first Tab shows the different types of internal hardware connections your computer has, IDE and SATA, along with what is connected to them (i.e. DVD Rom drive, hard disk) * Under Advanced Tab, CPU configurations can be changed if options are available (i.e. overclocking) * Under Power Tab, outputs are shown for power outputs of hardware devices (i.e. voltages used and cooling fan speeds, and temperatures of hardware * Under Boot Tab, you are allowed to set up the sequence in which the computer will boot up from (i.e. hard drive, CDROM, or Removable) * Under Exit Tab, You are given the option on how to exit from BIOS with or without saving changes Explain POST: Power On Self Test * POST is a test to determine a computer’s hardware is not faulty before it boots * When a problem occurs BIOS will register an error * A sound messaging speaking is located on the motherboard that will issue a series of beeps when a problem is found.
h. The following additional special guidelines apply to possession and use of cell phones: (1) Your Primary TAC will collect and store your and your class members’ cell phones: when your class receives phone privileges, your phone will be returned to you. (2) Provide your Administrative Officer your cell phone number to include the area code; the Administrative Officer will consolidate information for your class and provide it to the Primary TAC. (3) Once your cell phone is returned, you must keep it turned off and secured in your personal security area (PSA) except during authorized use times or when you remove it for charging. Unsecured cell phones and cell phone chargers will be treated as violations of physical security. (4) You may text message, but only during authorized phone use times.
