How does an inline UPS protect computer equipment against electrical power brownouts and blackouts? An inline UPS protects computer equipment against electrical power brownouts and blackouts are by grounding excess electrical voltage. What is the purpose of LoJack? The purpose of LoJack is that It allows the owner of a device to remotely locate, lock, or delete all files from the device. How should a technician dispose of an empty inkjet printer cartridge? A technician disposes of an empty inkjet printer cartridge by following local regulations for disposal. What is indicated by the contrast ratio of a monitor? The contrast ratio of a monitor is the difference in the intensity of light between the brightest white and darkest black that can be displayed. Which is a BIOS security feature that can prevent data from being read from a hard drive even if the hard drive is moved to another computer? The BIOS security feature that can prevent data from being read from a hard drive even if the hard drive is moved to another computer is a drive encryption. What are two reasons for installing a second hard disk drive inside an existing computer? Two reasons for installing a second hard disk drive inside an existing computer is to increase the CPU speed and to allow access to a secondary display output. What data is stored in the CMOS memory chip? The data that is stored in the CMOS memory the chip is the BIOS settings. Which two components are commonly replaced when a computer system with a newer motherboard is being upgraded? The two components that are commonly replaced when a a computer system with a newer motherboard is being upgraded with CPU and RAM. A technician has just finished assembling a new computer when the computer is powered up for The first time, the POST discovers a problem. Does the POST indicate the error? The POST discovers a problem by the LED on the front of the computer case flashes several times. A technician has assembled a new computer and must now configure the BIOS and at which point must a key be pressed to start the BIOS setup program? The key that needs to be pressed to start the BioS setup program is during the POST. What is one purpose of adjusting the clock speed within the BIOS configuration settings? The purpose of adjusting the clock speed within the BIOS configuration settings is to allow the computer to run slower and cooler. A technician has been asked to configure several computers with RAID but the customer needs protection if two drives fail and want as much drive capacity as possible. Which RAID should the technician install? The RAID needed to have as much drive capacity as possible is RAID 6. What is a function of the BIOS? The function of BIOS is to provide temporary data storage for the CPU. A data analyst has asked a technician to help protect locally stored data by installing a RAID. What is the minimum number of drives the technician has to install if configuring a RAID level 10? The minimum number of drives that has to be installed is four. What type of interface was originally developed for high definition televisions and is also popular to use computers to connect audio and video devices? The type of interface originally developed for high definition televisions which is also popular with computers to connect audio and the video device is HDMI. What two considerations would be of the greatest importance when building a workstation that will run multiple virtual machines? The two considerations that will be used as a greatest importance that will run on multiple virtual machines are the number of CPU cores and the amount of RAM.

Operators in C language

Operators One of the most important features of C is that it has a very rich set of built in operators including arithmetic, relational, logical, and bitwise operators. An operator can be any symbol like + - * / that specifies what operation need to be performed on the data. For ex: + indicates addition operation * indicates multiplication operation Operand VS Operator • An operand can be a constant or a variable. • An expression is a combination of operands and operators that reduces to a single value. For example: Consider the following expression: a+ b Here 'a' and 'b' are operand while 't' is an operator Operators & Expression are 1) Arithmetic Operators and Expressions 2) Assignment and Compound Assignment Operators 3) Increment and Decrement Operators 4) Relational Operators and Expressions 5) Logical Operators and Expressions 6) Bitwise Operators and Expressions Arithmetic Operators An arithmetic operator performs mathematical operators such

3D printers

3D  printers  A 3D printing or additive manufacturing is a process of making three dimensional solid objects from a digital file. The creation of a 3D printed object is achieved using additive processes. In an additive process of an object that is being created by laying down successive layers of material until the object is created. Each of these layers can be seen as a thinly sliced cross-section of the object. 3D printing is the opposite of subtractive manufacturing which is cutting out / hollowing out a piece of metal or plastic with for instance a milling machine. 3D printing enables you to produce complex shapes using less material than traditional manufacturing methods. Slicing: From printable file to 3D Printer Slicing basically means slicing up a 3D model into hundreds or thousands of layers and that is done with slicing software. When your file is sliced, it’s ready for your 3D printer. Feeding the file to your printer can be done via USB, SD or Wi-Fi. Your sliced file is now
