Computer Hardware Components And Accessories

Computers are made of different components or parts, collectively known as PC hardware. Some of the main hardware PC units include CPU, mouse, display screen monitor, hard disk, keyboard, CD drive, etc. You can buy a computer from a branded company or purchase an assembled model through a professional computer software person. Many a times, when some parts of a computer get corrupted, you can also buy separate components from any online or offline computer dealers.

Likewise computer hardware parts also do include novel items such as scanners, sound cards, internet modems and even digital cameras. But, every computer has individual properties like RAM memory, CPU model details, etc which may vary from other computers.

Let us study about some of the most important computer hardware parts:

* CPU- This part is the brain of the computer. It is known as Central Processing Unit and works as a processor. The most popular processors are manufactured by Intel popular as the Pentium Chip model. Intel processors are widely used all over the world by most of the computer manufacturing companies.

* Mouse- This hardware is essential for desktop models as navigational object, to click on varied options, selecting different objects and accessing necessary information on the computer screen. There are two main buttons in the mouse, to be used to access info. Nowadays, you can find interesting types of mouse in the market such as laser mouse or ball mouse. But, they all serve the same purpose to help access computerised info from the CPU.

* Hard Disk- This is a device that helps in storing data. The all-round performance of any computer actually depends on the speed of its hard disk. Higher rotational speed of the hard disk enables fast and high speed performance by that particular computer.

* RAM- It is also known as Random Access Memory, which aids in storing of temporary information in the CPU. When you switch off the computer, such temporary info files are erased. The optimum performance of the computer also depends on the size of its RAM.

* Keyboard- This is one of the most important part in computer hardware. Keyboard helps users to enter specific commands by punching of alphabets, numbers or signs. There are other function keys like Control, Alter, delete, F keys, Page up, Page down, etc in the keyboard. There are a total of 101 keys in any standard keyboard, and designed in such a way so as to make typing faster and easier.

Other additional computer hardware includes scanner, joystick, external drive, printer and servers. Buying individual computer hardware parts can be a tedious task as there are variety of selection models, styles and designs to choose from. It is best to gather some basic first hand info about the specific computer hardware part that you intend to buy.

You can choose to buy from online computer hardware retail shops and other hardware dealers. Online directories can help you sort a list of potential manufacturers or retailers who are genuine and trustworthy.



Computer Forensics Chain Of Custody

As the trend for high-specification mobile phones and computers continues at a rapid pace so too does the potential for electronic media misuse and abuse. This kind of fraudulent activity is becoming more commonly seen in legal cases, particularly with employment tribunals. Legal firms are beginning to employ the services of computer forensics experts more widely in documenting electronic evidence and providing litigation support, as this can be crucial in the outcome of cases.

Computer forensics can be used to track and provide evidence in cases of intellectual property theft, money laundering, hacking, moonlighting and the accessing of illegal or inappropriate websites. Digital forensics can also help to secure concrete evidence of illegal activity not usually associated with electronic devices including blackmail, drug dealings and abusive behaviour.

Regardless of whether digital forensics is being used in a criminal case or a civil matter (even as part of an E-discovery exercise), maintaining chain of custody is vital. This is the fully documented tracking of evidence for the period of time that the forensics team has possession of an electronic device. It ensures that each member of the team can be held accountable for any action that they take with the media.

The purpose of this chain is to log the movements of the data, how it has been stored and subsequently analysed. It is essential that this documentation presents an accurate description of any copying, transportation and storage that has occurred, to prevent any potential legal challenge.

It is worth pointing out the differences between e-discovery and computer forensics. E-discovery is the method of processing and manipulating electronically stored information to be used in legal cases. This can take the form of emails, word processed documents, images and any other type of file, which can be filtered, viewed, analysed and categorised effectively via this system. E-discovery using a forensically acquired data set is crucial in maintaining the integrity of any information present, while potentially recovering any deleted material that may be appropriate for the legal proceedings.

Computer forensics is a highly complex industry that requires the latest in product knowledge and technical expertise. Specialists will have years of experience in the on-site capturing of data from computers, servers and other forms of electronic media. This data is then analysed by their forensic analysis specialists, and used to track how a particular device has been used. All areas of the chain of custody documentation will be completed to the highest standard to ensure peace of mind for the client.



Wireless Broadband Internet

Wireless Internet refers to a network that enables you to access the internet without necessary using any cables. The medium used in wireless internet is airwaves or radio waves, through which data is transmitted from one device to another. Most people prefer wireless internet to cabled internet connections due to its advantages. Manufacturers too are always producing electronic and communication devices that can access wireless internet.

There are various ways of accessing wireless internet. The first is via satellite. This type of wireless internet communication is mostly by governments organizations such as the military, and other big cooperations. For you to access wireless internet via satellite, you need a dish/receiver which will be fixed permanently on the ground or a structure such as a mast or tall building. This receiver is then positioned at an angle corresponding with the international satellite station which orbits the earth. This wireless internet connection is faster in speed and more convenient, especially where remote areas are involved. However, it is a bit costly for small businesses and individuals to set up and run. It is also affected by rain and the connection signal can be lost if there is obstruction between the two devices.

The other is through wireless broadband. In this case, an office or a home can be connected to the internet through a wireless broadband modem. The antenna/receiver is mounted on a raised services, say a roof top. The antenna then picks the internet signal from the internet service provider (ISP), and relays it to a modem. The modem then connects to a router which distributes the internet to various available devices. There are a also portable modems in the market which can be used to deliver wireless internet. This type of wireless internet is relatively cheaper than satellite to set up and run. It can also allow a number of devices to be connected to the internet at the same, hence making it cost effective. Connection speeds here are fast enough. However, setup costs for this wireless internet may be incurred.

Broadband wireless internet can also be offered by mobile telephone companies. These companies use their existing network of base stations to give wireless internet connections to their customers alongside other telecommunications services. Cellular internet uses a set of rules called WAP (Wireless Application Protocol), which enables mobile phones to connect to the normal internet and allow access to various online services. Therefore for you access such services, your cellphone must be internet enabled. Extra charges other than the normal cellphone calling rates may apply, depending on the company offering the wireless internet service.

Compared to other types of internet access, wireless internet is more convenient due to its mobility. You can have wireless internet on your cellphone, laptop, pocket PC or tablet and still move around without worrying about jacking away any connected cables. Wireless internet is therefore recommended for people who are always on the move.

The one concern about wireless internet has been its connection speeds, which have been slower than those of cable internet. Previously, wireless internet has been offered on technologies such as GPRS and EDGE. They are now being replaced by better and faster wireless internet technologies such as 3G, 4G and WiMAX. This guarantees connection speeds which much those of cable, while still using wireless internet.

3. Create and enforce a password policy – try password managers or start by using hard-to-guess passwords with alpha numerals and special characters.

4. Don’t take chances – to avoid being compromised, change the network whenever an employee is retrenched or voluntarily quits. This way a disgruntled employee can’t mess you up.

5. Educate your staff – ensure that they don’t click or install suspicious links and attachments. Make them run all downloaded programs through an antivirus program.

Simple Web Design Techniques to Help Create Websites for Businesses

Websites are more than just a platform to stuff loads of information on. They can also be a presentation and a direct image of your business. A clean and precise website represents a professional and efficient company. Web design is important and must be approached carefully to ensure your website does not only just display all the necessary information; but also looks and feels great to use. Here are some simple methods to help you design and develop a great looking website.

1. Create a logo that represents you Every business or brand needs a logo that represents them. There is nowhere better than to display that logo on your website where everyone can see it. Whether you already have a logo or need to create one; implement it into your website design and have it link to your homepage. The most common and probably the best position to place the logo would be at the top left of you website. This helps to improve brand awareness and helps users to navigate the website more easily.

2. Easy to use and simple Navigation One of the most important features of any website is the way users will navigate it. What is the point in creating all these web pages that are rich in information and have the users not able to display them. The main thing to think about when designing a navigation system for your website is to keep it simple. Aunique and complicated navigation bar can be fun and exciting, however, if the users are required to learn how to use it then most likely they will leave your website. Try to stick with the standard horizontal navigation bars that most websites use. This will provide a navigation system that almost all users will instinctively be able to use. Try to keep the amount of headings to about 5 – 8. You don’t want too many different pages but you also don’t want to clutter your content.

3. No clutter please When it comes to writing content for your website, it is easy to get distracted from what’s important and to just overload with unnecessary text and images. Users want to be able to access the information they need quickly and precisely so avoid creating long paragraphs and try to simplify it; use bullet points or tables. A principle that a lot of web designers use is the Pareto principle. The Pareto principle states that “roughly 80% of the effects come from 20% of the causes”. Now to translate that into website design, this means that 20% of the content on the page should display 80% of the overall information and result. Try to keep the important stuff above ‘the fold’. The fold is the area of the site that users can see without scrolling. The fold is important as this is the first part of the website the users will see on any page.

4. Choose the right colour scheme and font Try to select appropriate colours and fonts, and stick to it! It is easy to pick a load of different colours and implement them everywhere on your site, but a simple design will take you a long way. Try to create a colour palette of about 2-3 different colours. This will help to create a clean and consistent appearance. Picking colours is easy; the difficult part is how to use them. A useful way to use colours is to highlight what’s important. Choose a font that is easy to read, you have to take consideration of the different sizes of screens or even platform. Users will access your website from a desktop pc or a mobile device. The font should accommodate the two platforms to create a website that is easy to read and looks great.

5. Choosing the right graphics Images are a great way to represent information or make a site look good. Make sure the graphics you use are related to the information on the page and are high quality. Always use high resolution pictures. This will ensure the images do not appear pixelated. Using original photos are a great way to show authenticity of a business. Invest in professional photography to catch user’s attention.

6. Use space effectively Using the space available can affect the overall experience. Create space between paragraphs and images to give the user ‘breathing space’. The ‘white space’ can help to control the flow of the website and helps to guide users from one bit of information to the next. When it comes to creating a website, always think about the users and how you want them to perceive you as a business. Keeping a site simple and clean will help to create an easy to use site but also helps keep it future proof. Simple is the new web design standard of the future and more and more companies are designing simply. Think about the important stuff and get rid of what is unnecessary.

Some Ideas About Development And Design Of Websites

There’s two ways to get a website developed – pay, or design it yourself. If you’ve chosen the latter, you’ll need several things. First, you’ll need web hosting. Web hosting can range from $2 to $200 per month, depending on your needs. Consult a web hosting review site for more information. Next, you’ll have to have some background in computing or internet programming. You’ll need to know at least HTML. Thirdly, you’ll have to have a way to upload your files. Some hosts have online uploads, others require FTP.

Today’s web design encompasses many different technologies that must blend seamlessly to allow for the best combination of form and function in a site. If you’ve decided to design your first website, it can be a daunting task. Rather, most professionals suggest finding a low-cost alternative. Many web developers have a forte – either design or programming. Finding a well-rounded website design firm or individual is difficult, but the business’ portfolio is the best indication.

In order to be certain of the firm’s abilities, further scrutinizing is imperative. The firm has a nice looking site that flows well and has an aesthetic appeal, a great testament to their abilities. But does this eye for the creative flow through its clients’ sites, too? It’s importance to be certain of this question. Browsing through the portfolio alone often isn’t enough. Get feedback from the clients if possible (with the firm’s approval). Are they satisfied? Do they feel that the firm was easy to work with? And moreover, is there site an adequate representation of what they wanted?

Once you’ve found a firm that you feel is worthwhile, it’s time to ask for a quote. Hopefully, the firm has a questionnaire that you can easily fill out. These surveys will ask questions about how many pages your site will have, whether writing is necessary, and if there is any extra functionality. You probably already have a budget in mind, but it’s better for a company to tell you what they think the work is worth. They know how many hours of work are involved, and will (hopefully) break down the price for you to let you know exactly what you’re paying for. Web design can range from $5 to $100 per hour, and many web designers have a forte that they will charge more for. Sometimes, it’s even necessary to work with multiple firms to get the best deal.

Today’s trend is outsourcing. Many Indian and other overseas programmers and designers are willing to work for exponentially less than American web designers. This trend has its pros and cons. While the money saved is beneficial, the overseas designers rarely speak fluent English. Communication is an imperative part of web design, and often projects can go awry without it.

Obviously, you have a difficult design ahead of you. With all the great web design firms out there, sometimes cost does equal quality. Make a decision, get a second opinion, and always be thorough in your explanation of what you’re looking for.
