2. WHAT IS COMPUTER SPECIFICATION?

3. COMPUTER SPECIFICATION The specification or ‘spec’ is a list of the key components that make up the computer. When reviewing a computer specification, the most important components to take are the processor, the size of RAM, and the size of the hard drive as these are central to the overall capability of the system.

4. UNDERSTANDING SPECIFICATION PC SPECIFICATION Intel or AMD Processor Model Number 2 GB SDRAM 160 GB Hard Drive 17” Flat Screen Color Monitor Integrated Graphics/Sound Card Microsoft Windows 11 Pro Processor Information Memory Information Hard Disk Information Monitor Information Video/Sound Card Information Operating System Information

5. PROCESSORS Two companies - Intel Inc. and AMD Inc. – are the manufacturers of most of today’s PC processors and both offer a range that balances price and performance. Processors are generally defined by their speed, in gigahertz (GHz), and this relates to the number of operations they can perform per second.

6. PROCESSORS The higher the value, the faster the PC will perform and the more expensive it is. More recent and more powerful processors use a 64-Bit architecture, rather than the previous 32-Bit models.

7. PROCESSORS ENTRY LEVEL PROCESSORS MID-RANGE PROCESSORS HIGH-END PROCESSORS Office Applications Internet Browsing Basic Graphics Program Home Computing Educational Software Office Applications General Multimedia Applications Internet Browsing Processor Intensive Multimedia Creation Application Office Applications Internet Browsing PROCESSOR TYPE PROCESSOR TYPE PROCESSOR TYPE Intel Celeron AMD Sempron Intel Pentium 4 AMD Athlon (32 Bit) AMD Opteron Xeon AMD Athlon (64 Bit)

8. MEMORY The main working memory in a computer is called random access memory or RAM. The processor uses this memory to run programs. RAM is measured in gigabytes (GB). Most modern computers use DDR 2 RAM

9. THE HARD DRIVE (STORAGE) The hard drive is the computer’s primary storage area. It stores the applications and programs that run on the PC, as well as any work created by users. The capacity of the hard drive, measured in gigabytes (GB.

10. THE HARD DRIVE (STORAGE) A hard drive capacity of at least 80GB is recommended for general-purpose PCs. A hard drive capacity of 200GB or more is recommended if working with multimedia applications where large graphics and digital audio/video files are being created and stored.

11. MONITORS The older Cathode Ray Tube (CRT) has been largely replaced by Liquid Crystal Display (LCD) and Light Emitting Diode (LED) flat-screens. Average entry-level PCs usually come with a 17” flat screen and this is adequate for most general purpose applications.

12. MONITORS Larger 19” flat screens are available and may be appropriate if video editing and advanced graphics work are being carried out. Teachers of students with special needs may want to consider using larger monitors with their students.

13. GRAPHICS/SOUND CARD These cards are installed inside a PC and are responsible for determining the quality of the audio and visuals (graphics and video) output by the computer. They hold their memory (in MB), which is why they add to a computer’s capability.

14. SPEAKERS AND HEADPHONES Most computers come with either built-in or external speakers. Schools may also consider buying headphones to control sound levels within a classroom or computer room. Cheap ‘headphone splitters’ can also be purchased — these enable two sets of headphones to be used per computer.

15. NETWORK INTERFACE CARD It is recommended that all PCs be purchased with a suitable network interface card (NIC). A network card allows a computer to be connected to a network. A 10/100/1000 Mbps (Megabits per second) card is the standard network card today. Few school networks currently operate at speeds higher than 100Mbps.

16. OPERATING SYSTEM (OS) PCs are generally purchased with an operating system pre-installed. It may be possible to choose a particular operating system and, if so, this may help standardize new machines with existing school PCs. At present, Microsoft’s newer OS is Windows 11.

17. ACTIVITY 4.1
