HTTP: (Hypertext Transfer Protocol) the client/server protocol that defines how messages are formatted and transmitted on the World Wide Web.

FTP: (File Transfer Protocol) a standard procedure that allows one computer to transfer files to and from another over a network such as the Internet.

Hyper text: Hypertext most often refers to text on a computer that will lead the user to other, related information on demand

Benefit: What would be the positive side of upgrading, i.e. from UNIX terminal to a VPN

Security: techniques for ensuring that data stored in a computer cannot be read or compromised by any individuals without authorization. Most security measures involve data encryption and passwords. Since 10 computers are running on a network, security is priority.

Growth: Upgrade will expand and improve work

Delivery time: Upgrading will reduce waiting period to 2 – 3 hours as data will quicker to providers

Software and hardware: Whilst upgrading software, hardware may need to be upgraded to meet with the system requirements

Support: Giving advice or help to the user often in instructional manual or telephone support. The often be useful in cases of emergency or something has happened.

Configure: To set up a program or computer system for a particular application

Optimise support: Provide assistance that a vendor offers to customers. Support can vary widely

Install: To connect or set in position and prepare for use. In computer terminology, install usually refers to putting software on a computer (install the software), or adding hardware components to your computer (install the hardware).

Uninstall: To remove an application from a computer. Uninstalling removes all files that were added to the computer when the application was initially installed

Upgrade: A new version of a software or hardware product designed to replace an older version of the same product

Compatibility: The ability of one device or program to work with another device or program.

2. Information is the definite knowledge acquired or supplied about something or somebody. It can also be the collected facts and data about a specific subject. E.g.

3. A database is used for to arranged collection of data where it can be managed to create, store and manipulate information efficiently.

4. Paper survey

5. Library books database

6. Field: Information such as characters or numbers can be entered and manipulated. E.g. author, the title, and the subject headings
Record: a collection of related items of information. E.g. An account of an employee
File: a uniquely named collection of program instructions or data stored on a hard drive. E.g. the name of the data searched in a library database

7. The main purpose of a primary key is to implement a relationship between two tables in a relational database
Student name No
Student address No
Student number Yes, because student all have unique numbers and is a quicker way to search a specific data
Student DOB No
Student’s form No

Car model
Car make
Colour
Registration number: Yes, because every car has a unique number registered onto the car
Number of doors

8. The difference between a flat-file database and a relational database is that flat-file presents records in single line and Fields from each record may simply have a fixed width with padding. A relational database is defined as a set of tuples that all have the same attributes. This is usually represented by a table, which is data organized in rows and columns.

9.
Alphanumeric (text): Text and text with numbers combined
Number: Numbers including those with decimal places
Currency: Currency values and numeric data used in mathematical calculations involving data                                Date/Time: Date and time values
Logical/ Boolean/ Yes No: Yes and No values and fields that contain only one of two values
Autonumber: A unique sequential (incremented by 1) number or random number assigned

Give an example for the following datatypes
Alphanumeric (text) Postcode – CV64 3RT
Number Age – 13
Currency Dollars – $50
Date/Time Date borrowed – 20/02/08
Logical/ Boolean/ Yes No Agree or disagree – tick box
Autonumber Student ID

Which would be the most appropriate datatype for the following?
£15.99 Currency
NQTR56N8J Text
15, Pear Tree Avenue Address
14th November 2002 Date/time
Male Female Logical
16 number

10. it is important to have an appropriate length of field because data can be useless or exceed sufficient information

Decide which would be appropriate field lengths for the following fields
Gender (male/female) 6
Forename 20
House number and street name 15
Postcode 4
Telephone number 10

11. Database validation involves checking the database file to ensure that the various data structures retain their integrity and internal consistency

12. rule stating that the quality of the output is a function of the quality of the input; put garbage in and you get garbage out

13. Testing the comfirm that the system, subsystem or components must documented requirements or specification on the design

14.

Think of two advantages of coding data

• To reduce the amount of data input
• Creates shortcuts

Think of a disadvantage of coding data

• The codes could have common data

(B)The advantage of using an attachment in an email allows the you the original file content without pasting on the email

(C) CPU processor, RAM, Hard drive disk

(D) The benefit of indentifying hardware specification allows the company to keep a record of what products they have, what are in use and to work out whats missing.

Finish: 5:00pm

Equipment used:  Screwdriver [the one and only equipment you need to take your computer out..]

Tasks Completed: Take computer system box into separate parts [e.g. Motherboard, RAM, Power supply etc.]. After taking system box into parts, the parts needs to be reconnected to the right fixings.

New Skills learnt: Learn how to put the screws properly using the index finger and also how simple it is to build a computer from zilch

How could i improved? learn components of a motherboard

• Set up recovery actions to take place if a service fails, such as restarting the service automatically or restarting the computer.
• Turn services off if you suspect they may be causing a problem
• Diagnose if a service is currently running or if it has stalled
• Create custom names and descriptions for services so that you can easily identify them

• Systems tools
• Storage
• Service applications

Snap-ins can take the form of monitor controls, tasks, wizards and documentations controls required to manage many of the hardware, software, and networking components of Windows. You can add items to an existing MMC console, or you can create new consoles and configure them to administer specific system components.
