(Choose two answers.) a. Used for short-term memory b. Used for long-term memory c. Used to process data d. Connects to the CPU over a bus using a cable e. Is installed onto the motherboard 5. This chapter describes the concepts behind how a CPU reads the contents from RAM.
Provide a comparison table showing the similarities and differences between Desktop and notebook computers Similarities | Differences | Functionality: Both types of computers provide expansion ports, CD/DVD drives, keyboards, mouse, both audio output and visual display | Power Source: The desktop computer extracts power from the wall outlet and may provide hundreds of watts of power whereas a laptop relies upon a rechargeable battery for power | Software: Both types of computers can run on the same operating system and application programs. | Size: The desktop computer sits on a hard surface and is not easily portable. The notebook computer sits on the top of a hard surface or upon your lap and is easily portable. | Power Saving: Both types of computers can hibernate or sleep when not in use. | Components: The internal components of a desktop computer are not designed for low power operation.
Introduction to Programming NT1420 Unit 1 Assignment 1: Homework Short answer questions and answers: 1) Why is the CPU the most important component in a computer? The CPU is the part of the computer that actually runs the program. 2) What number does a bit that is turned on represent? What number does a bit that is turned off represent? A bit that is turned on represents the number 1.
Used for short-term memory; Used to process data 5. This chapter describes the concepts behind how a CPU reads the contents from RAM. Which of the following is true about the process of read data, as described in the chapter? The CPU tells the RAM which address holds the data that the CPU wants to read 6. A user has opened a word processor, typed the numbers 123456789, and stored the document as a file called report1.
POST (or P.O.S.T.) is a series of system checks run by computers, as well as, on other electronic devices when they are powered up. 2. What are the roles of BIOS and the POST procedures? BIOS load the operating system into the computer’s memory and finishes up the boot-up process.
| NT110 | Unit 6 Research Paper 1 Network Attached Storage | | | 7/30/2013 | | Network- attached storage device or NAS is basically a small scale server used for storing data and file sharing. It allows more hard disk storage space to be added to a network that already utilizes servers without shutting them down for maintenance and upgrades. It is often referred to as a computer appliance. They can be purchased or can be built by using an old computer and spare parts. The speed of a NAS varies depending on the unit you have but are typically one gigabit with an Ethernet connection.
Which type of memory is considered volatile?- RAM 10. A(n) ________ is similar to a notebook computer, but the monitor swivels and folds flat.- tablet PC 11. What is the difference between Sleep mode and Hibernate in Windows 7? - Sleep mode saves everything to memory, whereas Hibernate stores your data on your hard drive and your computer is powered off. 12.
One difference between BIOS and CMOS is that CMOS is written in random access memory (RAM). That is why CMOS is not permanent and may be edited by the user. A battery is required to keep the CMOS configuration settings when the PC is powered down. If the battery becomes low the system tray clock will begin to loos time. If it dies completely or is removed you will get a checksum error during boot up and the process will stop.
Daniel Bowden PT1420 Intro to Computer Programming 6/25/14 Unit 1 Research Assignment 1 Exploring Computer Languages A program does nothing more than tell the computer how to accept some type of input, manipulate that input, and spit it back out again in some form that humans find useful. Table 1 lists some common types of programs, the types of input that they accept, and the output that they produce. Machine language is a set of instructions executed directly by a computer's central processing unit (CPU). Each instruction performs a very specific task. Every program directly executed by a CPU is made up of a series of such instructions.
However, switches filter data according to the MAC address. This can reduce congestion and decrease the collision domain (Ciccarelli, et al 2013). Switches support management capabilities and some provide built-in web servers for management over the Internet (Ciccarelli, et al 2013). Switches allow the network to be grouped into segments and can limit the amount of broadcast traffic that is propagated between segments (Ciccarelli, et al 2013). Because of their sophistication, switches can be more expensive, difficult to configure, and can increase the complexity of a network (Ciccarelli, et al 2013).
