I’m not sure if this means I am a bad person, but the first thing I thought of in

regards to disposing of old computers, was making sure all of your personal data was wiped, not

about recycling. I think one of the most important things you can do when getting ready to

dispose of a computer is to make sure you properly delete all personal information that may be

left over on your hard drive. People have computers that “die” or are not able to work anymore,

so they might think just throwing them away is safe. But someone who has even a little

knowledge about computers can easily open up your laptop or desktop and take out your hard

drive. Hooked up to another computer, it would be very easy for them to scan it for personal

information. t’s odd to think about replacing a motherboard, because I have actually considered

this on personal computers I have owned in the past. But when I talk with some friends who are

not as comfortable with changing out hardware, they often times feel so lost because they are not

really sure what to look for when purchasing components, such as a motherboard. I think the first

thing you need to decide on when shopping for a motherboard, is what is it going to be used for?

Are you using your computer for just checking emails and Facebook? Or will you be doing some

heavy processing, such as gaming or video editing? I would assume that someone who is

actually shopping for a motherboard is doing so because they want to upgrade their computer. So

it’s probably a safe bet to assume they will want one capable of supporting heaving processing. I

think one of the most important things you can look at when shopping for a new motherboard, is

to ensure you are looking at a motherboard that is going to be able to support your chipset.

Something as simple as that would put a huge…...

The Basics of Computer Hardware

...Basics of computer hardware The Basics of Computer Hardware By: Stephen Lomangino Dr. Fahey ITT-Technical Institute: College of Information Technology Abstract This paper identifies the many different parts a computer needs to operate and perform basic tasks. Among these are the motherboard, central processing unit (CPU), and random access memory (RAM). While these components are somewhat mandatory for computer performance this paper will also cover optional pieces of hardware that can improve quality and speed of the computer. These can include graphics processing units (GPU) and additional RAM. All parts of the computer can be upgraded but one must take into consideration the size and airflow capabilities of the computer case to be sure that all upgrades will fit without getting too hot or crowded. If the case were to get too hot the CPU could overheat and shut down the computer. Due to this possible situation this paper will go over the special precautions that must be made to accommodate the size and heat generation of upgraded hardware. The Basics of Computer Hardware Building a computer is similar to building a house, first you build the foundation then everything gets built on top of it. Instead of building on concrete, the foundation for a computer is the case and the motherboard. The case is equivalent to the walls and ceiling of the house, once you have those you can put any other amenities into the house as needed.......

Computer Hardware and Software

...Identify hardware and software needed to secure your choice of networks against all electronic threats. Networking hardware is hardware that is used to help work stations connect to a server. Although there are many different kinds of hardware like bridges, network cards the networking hardware that I have chosen to use in within my company’s network are routers, firewalls and switches. Using both routers and firewalls will help protect not only wireless networks but also those networks that use Ethernet cabling. I chose this hardware because I felt that it’s the best hardware to use when keeping my company’s network safe. The software that I have chosen to use is McAfee Anti-virus security software. This software along with the firewall will keep my company’s network safe and secure. Routers along with firewalls are the top network security hardware needed when it comes to keeping a network almost if not all totally secure. The firewall blocks out any unwanted activity as well block hackers from possibly hacking into our networks and stealing important information that pertains to our company and its customers. Along with the router and firewall networking software also plays a major part. The software is what the firewall uses to create its security barrier over the network. McAfee is one of the top manufacturers when it comes to network security. This software enables the use of not only the internet’s firewall but also the ability to detect viruses, anti-spyware......

Hardware Low End Computer

...Hardware 12/27/12 Scenario 1 Scenario 1 Low End Workstation Have you ever built a low end workstation for a business? Have you ever wanted to know how to build a computer? Have you ever wondered how to make a computer on your own with step by step directions? To build a low end workstation for a business or server you would have to have the proper motherboard, computer case, RAM, power supply, hard drive, CPU, and a DVD disk drive. When you are looking to build a computer you need to make sure that all of the parts are compatible and will fit in your tower. I would first look for a motherboard and computer case. I went with a biostar G41D3 motherboard. It is a micro ATX so you will have to make all of your components will fit onto it. You will have to pick a tower that will fit the micro ATX motherboard. I chose the cooler master elite mid tower case. I chose this case because it will have more air flow since it will be a server so it will probably be running more frequently than a regular computer. I then chose a hard drive. To choose a hard drive you have to know what kind it is. Usually the motherboard will come with a list of compatible hardware. The motherboard I chose is compatible with a SATA hard drive.I chose an intel dual processor because it does not need to perform a lot of tasks at once and it goes with the motherboard. You can find out that the motherboard and the CPU fit together by looking at the specifications of the motherboard. I chose a Toshiba 1......

Computer Hardware

...Computing hardware evolved from machines that needed separate manual action to perform each arithmetic operation, to punched card machines, and then to stored-program computers. The history of stored-program computers relates first to computer architecture, that is, the organization of the units to perform input and output, to store data and to operate as an integrated mechanism. Before the development of the general-purpose computer, most calculations were done by humans. Mechanical tools to help humans with digital calculations were then called "calculating machines", by proprietary names, or even as they are now, calculators. It was those humans who used the machines who were then called computers. Aside from written numerals, the first aids to computation were purely mechanical devices which required the operator to set up the initial values of an elementary arithmetic operation, then manipulate the device to obtain the result. A sophisticated (and comparatively recent) example is the slide rule, in which numbers are represented as lengths on a logarithmic scale and computation is performed by setting a cursor and aligning sliding scales, thus adding those lengths. Numbers could be represented in a continuous "analog" form, for instance a voltage or some other physical property was set to be proportional to the number. Analog computers, like those designed and built by Vannevar Bush before World War II were of this type. Numbers could be represented in the form of digits...

There are so many options to choose from brand, size and performance. This paper will discuss and compare some of today’s best bargain laptops and computers that will also offer some of today’s most updated software and features. I will also discuss two of the most popular smartphones comparing and contrasting each devices features. While shopping on the internet for the best computer system I had hundreds of choices. I decided to narrow my choices down by picking a device that had all the features I needed in a computer system, but had a reasonable price tag for a full time worker and a part time student budget. The best option for me is the Dell Inspiron 660, and the Canon PIXMA MG2220 all-n-one printer it has all the features and needs that I would need in a personal home desktop system.

...verdict. Sincerely yours, (Syed Shohan Shah) On the behalf of the group EXECUTIVE SUMMARY In this modern age computer is a very essential in our everyday life. It helps our every work. Without computer we can not live without a single day. It has many parts like hardware which are touchable and software which are untouchable. Computer users may use a scoring system of evaluation when there are several competing proposals for a hardware or software acquisition. They give each evaluation factor a certain number of maximum possible points. Then they assign each competing proposal points for each factor, depending on how well it meets the specifications of the computer user. Scoring each evaluation factor for several proposals helps organize and document the evaluation process. It also spotlights the strengths and weaknesses of each proposal. Computer Hardware 1.0 Monitor Multiple technologies have been used for computer monitors. Until the 21st century most used cathode ray tubes but they have largely been superseded by LCD monitors. Cathode Ray Tube The first computer monitors used cathode ray tubes (CRT). Until the early 1980s, they were known as video display terminals and were physically attached to the computer and keyboard. The monitors were monochrome, flickered and the image quality was poor. In 1981, IBM introduced the Colour Graphics Adapter, which......

Note that column names and table names do not have spaces...they must be typed as one word; and that the statement ends with a semicolon (;). The general form for a SELECT statement, retrieving all of the rows in the table is: SELECT ColumnName, ColumnName, ... FROM TableName; To get all columns of a table without typing all column names, use: SELECT * FROM TableName; Each database management system (DBMS) and database software has different methods for logging in to the database and entering SQL commands; see the local computer "guru" to help you get onto the system, so that you can use SQL.

Computer Hardware Components

...Discussion: Computer Hardware Components There where several different articles that I found that talked extensively about different computer hardware components. The one component that I found that was interesting and that I never know how many different computer components go into it is graphics cards. Graphics cards use every part of a computer to function correctly and they are built right into the card its self. They have their own RAM, some have their own power supply and they even have their own type of CPU that is called a graphics processing unit or GPU. The author, Jeff Tyson, went into detail on how the graphics card takes information from the CPU and makes it into a picture on your monitor. Tyson (2001) brock it down into lemans terms by saying: Think of a computer as a company with its own art department. When people in the company want a piece of artwork, they send a request to the art department. The art department decides how to create the image and then puts it on paper. The end result is that someone's idea becomes an actual, viewable picture. (P.1) I think it is just amazing on how the simple little card can take information and know how to put it on the monitor as a picture. What is even more amazing is how it works with gaming and is able to make these calculations that fast without any issues, that’s if you have the card that can handle the game. Most standard motherboards come with some type of graphics card but if you want to do more then......

Fundamentals of Hardware and Software

...SECTION 1 FUNDAMENTALS OF HARDWARE AND SOFTWARE A computer is an electronic device, operating under the control of instructions stored in its memory.  Input – accept data  Processing – manipulate data  Output – produce results from the processing  Storage – store the data and results for future use HARDWARE Hardware is the physical parts of the computer. There are five main components: 1. Central Processing Unit 2. Primary Storage devices 3. Secondary Storage devices 4. Input Devices 5. Output Devices 1. The Central Processing Unit (CPU) is also known as the processor. It is the brain of the computer and converts data into information. CPU speed is measured in Hertz. 1 hertz = 1 clock cycle/machine instruction per second 1 Kilohertz (KHz) = 1000 Hz 1 Megahertz (MHz) = 1000 KHz = 1 000 000 Hz (1 million) 1 Gigahertz (GHz) = 1000 MHz = 1 000 000 000 Hz (1 billion) A CPU with speed of 1 GHz can execute 1 billion machine instructions per second. There are two main parts of the CPU: A: Control unit – This controls the sequencing of operations of the CPU by fetching and decoding instructions and coordinating the input and output devices. B: Arithmetic Logic Unit (ALU) – This manipulates the data. It performs arithmetic operations (including addition, subtraction, division and multiplication and logical operations (including reasoning and performing the comparisons necessary to make decisions). 2.
